DETAILED DESCRIPTION

The present disclosure can be understood more readily by reference to the following detailed description, examples, drawings, and claims, and the previous and following description. However, before the present devices, systems, and/or methods are disclosed and described, it is to be understood that this disclosure is not limited to the specific devices, systems, and/or methods disclosed unless otherwise specified, and, as such, can, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular aspects only and is not intended to be limiting.

The following description is provided as an enabling teaching of the present devices, systems, and/or methods in its best, currently known aspect. To this end, those skilled in the relevant art will recognize and appreciate that many changes can be made to the various aspects of the present devices, systems, and/or methods described herein while still obtaining the beneficial results of the present disclosure. It will also be apparent that some of the desired benefits of the present disclosure can be obtained by selecting some of the features of the present disclosure without utilizing other features. Accordingly, those who work in the art will recognize that many modifications and adaptations to the present disclosure are possible and can even be desirable in certain circumstances and are a part of the present disclosure. Thus, the following description is provided as illustrative of the principles of the present disclosure and not in limitation thereof.

As used throughout, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “an element” can include two or more such elements unless the context indicates otherwise.

Ranges can be expressed herein as from “about” one particular value, and/or to “about” another particular value. When such a range is expressed, another aspect includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another aspect. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint and independently of the other endpoint.

For purposes of the current disclosure, a material property or dimension measuring about X or substantially X on a particular measurement scale measures within a range between X plus an industry-standard upper tolerance for the specified measurement and X minus an industry-standard lower tolerance for the specified measurement. Because tolerances can vary between different materials, processes, and between different models, the tolerance for a particular measurement of a particular component can fall within a range of tolerances.

As used herein, the terms “optional” or “optionally” mean that the subsequently described event or circumstance can or cannot occur and that the description includes instances where said event or circumstance occurs and instances where it does not.

The word “or” as used herein means any one member of a particular list and also includes any combination of members of that list. Further, one should note that conditional language, such as, among others, “can,” “could,” “might,” or “may,” unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain aspects include, while other aspects do not include, certain features, elements and/or steps. Thus, such conditional language is not generally intended to imply that features, elements, and/or steps are in any way required for one or more particular aspects or that one or more particular aspects necessarily include logic for deciding, with or without user input or prompting, whether these features, elements and/or steps are included or are to be performed in any particular aspect.

Disclosed are components that can be used to perform the disclosed methods and systems. These and other components are disclosed herein, and it is understood that when combinations, subsets, interactions, groups, etc. of these components are disclosed that while specific reference of each various individual and collective combinations and permutations of these may not be explicitly disclosed, each is specifically contemplated and described herein, for all methods and systems. This applies to all aspects of this application, including, but not limited to, steps in disclosed methods. Thus, if there are a variety of additional steps that can be performed, it is understood that each of these additional steps can be performed with any specific aspect or combination of aspects of the disclosed methods.

Disclosed is a sway brace fitting for a suspended pipe and associated methods, systems, devices, and various apparatus. Example aspects of the sway brace fitting can comprise a first jaw, a second jaw, and a clamp fastener. It would be understood by one of skill in the art that the sway brace fitting is described in but a few exemplary embodiments among many. No particular terminology or description should be considered limiting on the disclosure or the scope of any claims issuing therefrom.

FIG.1is a perspective view of a sway brace fitting assembly100, in accordance with one aspect of the present disclosure. According to example aspects, the sway brace fitting assembly100can be configured to support a suspended pipe, shown as piping820(shown inFIG.8). For example, the piping820may be suspended from a wall or ceiling of a building structure. Example aspects of the sway brace fitting assembly100can comprise a pipe strap110and one or more brace clamps130mounted to the pipe strap110. As shown, in the present aspect, the brace clamps130can comprise a first brace clamp130aand a second brace clamp130b. Other aspects can comprise more or fewer brace clamps130. In the present view, the first brace clamp130ais oriented in an engaged configured (i.e., a closed configuration), and the second brace clamp130bis oriented in a disengaged configuration (i.e., an open configuration), which are described in further detail below.

Example aspects of the pipe strap110can comprise a substantially U-shaped strap body115configured to cradle a portion of the suspended piping820. The U-shaped strap body115can define a terminal first strap end116generally at a first side112of the pipe strap110and a terminal second strap end118opposite the first strap end116and generally at a second side114of the pipe strap110. Each of the first strap end116and the second strap end118can generally be oriented at a top side120of the U-shaped strap body115, relative to the orientation shown, wherein the top side120can be substantially opposite a bottom side122. The pipe strap110can further comprise a strap mount124extending laterally outwards from each of the first and second strap ends116,118of the U-shaped strap body115. As shown, the first brace clamp130acan be mounted to a first strap mount124a(shown inFIG.2) of the strap mounts124and the second brace clamp130bcan be mounted to a second strap mount124bof the strap mounts124. One or more mounting fasteners126can be provided for coupling each brace clamp130to the corresponding strap mounts124.

According to example aspects, each brace clamp130can comprise a first jaw132, a second jaw134, and a clamp fastener136. In the present aspect, the first jaw132can be an upper jaw132, and the second jaw134can be a lower jaw134. Any of the upper jaws132described in the present disclosure could also or alternatively be formed as the lower jaw134, and any of the lower jaws134described in the present disclosure could also or alternatively be formed as the upper jaw132. Each of the lower jaws134can be coupled to the corresponding strap mount124by the mounting fasteners126. A clamp channel142can be defined between the upper jaw132and the lower jaw134of each brace clamp130. Furthermore, the upper jaw132can be pivotably coupled to the lower jaw134by a hinge145. Example aspect of the hinge145can comprise a hinge pin146, as shown. In the present aspect, the hinge145can be disposed proximate to a rear clamp end148of the brace clamp130, and the clamp fastener136can be disposed proximate to a front clamp end150of the brace clamp130. In the disengaged configuration, as illustrated by the first brace clamp130a, the upper jaw132can be pivoted away from the lower jaw134about a lateral hinge axis147to widen the clamp channel142therebetween. The brace clamp130can be unattached to the sway brace pipe830in the disengaged configuration, such that the sway brace pipe830can be movable relative to the brace clamp130. A sway brace pipe830(shown inFIG.8) can be inserted through the clamp channel142in the disengaged position, and the hinged connection between the upper jaw132and the lower jaw134can allow the clamp channel142to be widened as needed to accommodate sway brace pipes830of varying diameters.

In example aspects, the upper jaw132and the lower jaw134of each brace clamp130can be formed from a metal material, and in some aspects, the brace clamps130can be formed from a cast metal, such as cast ductile iron, or formed from sheet metal. In other aspects, such as the aspect shown inFIG.15, the brace clamps130can be formed from sheet metal. In other aspects, the metal material can be, for example, iron, aluminum, or the like. For example, each of the upper jaw132and the lower jaw134can be cast monolithically (i.e., formed as a singular component that constitutes a single material without joints or seams). In other aspects, the brace clamps130can comprise any other suitable material or combination of materials, including, but not limited to, other metals, plastics, composites, and the like, and the brace clamps130can be formed by any suitable manufacturing technique including being formed from sheet metal. In some aspects, the configuration, material, and manufacturing method of the upper jaw132and the lower jaw134can be determined based on performance requirements.

In example aspects, in the disengaged configuration, the clamp channels142of each brace clamp130can be open to define an open channel end144at the front clamp end150, as shown. The sway brace pipe830can be inserted rearwardly into the clamp channels142of the brace clamps130(i.e., in a direction towards the rear clamp end148) through the open channel ends144thereof, or the sway brace pipe830can be inserted laterally through the clamp channels142of the brace clamps130(i.e., in a direction from the first side112of the pipe strap110to the second side114of the pipe strap110or from the second side114to the first side112). Moreover, in the present aspect, both the first and second brace clamps130a,bcan be forward-facing (i.e., the open channel end144of the clamp channel142can be disposed at the front clamp end150). In other aspects, both of the first and second brace clamps130a,bcan be rearward-facing (i.e., the open channel end144of the clamp channel142can be disposed at the rear clamp end148.) In other aspects, the first brace clamp130acan be forward-facing, and the second brace clamp130bcan be rearward-facing, or vice versa.

In the engaged configuration, the upper jaw132can be pivoted towards the lower jaw134to clamp the sway brace pipe830between the upper jaw132and the lower jaw134. The brace clamp130can be secured in the engaged configuration by the clamp fastener136. According to example aspects, each of the clamp fasteners136can comprise a threaded clamp bolt138and a clamp nut140. The threaded clamp bolt138can be a hex bolt139, for example. In other aspects, the clamp fasteners136can comprise any other suitable mechanical fasteners known in the art. The threaded clamp bolt138can extend through the upper jaw132, as shown. In the disengaged configuration, the threaded clamp bolt138can be disengaged from the lower jaw134. In the engaged configuration, the threaded clamp bolt138can engage the lower jaw134, and the clamp nut140can be tightened on the threaded clamp bolt138to draw the upper jaw132towards the lower jaw134, clamping the sway brace pipe830(shown inFIG.8) therebetween. In example aspects, the clamp nut140can be a torque-off nut1510(shown inFIG.15), for example and without limitations. The brace clamp130can be attached to the sway brace pipe830in the engaged configuration, such that the sway brace pipe830can be retained in a secured position relative to the brace clamp130.

FIG.2illustrates the pipe strap110in accordance with an example aspect of the present disclosure. As shown, the pipe strap110can comprise the substantially U-shaped strap body115. The U-shaped strap body115can define the terminal first strap end116at the first side112of the pipe strap110and the terminal second strap end118at the second side114of the pipe strap110. Each of the first strap end116and the second strap end118can be disposed at the top side120of the U-shaped strap body115, and a curved pipe connection portion212can be disposed at the opposite bottom side122of the U-shaped strap body115. The first strap mount124acan extend laterally outwards from the first strap end116, and the second strap mount124bcan extend laterally outward from the second strap end118. In example aspects, a substantially perpendicular angle θ can be defined between each of the first and second strap mounts124a,band the U-shaped strap body115. In the present aspect, the pipe strap110can further comprise two of the mounting fasteners126extending through each of the first and second strap mounts124a,bfor coupling the first and second brace clamps130a,b(shown inFIG.1) thereto. In other aspects, the pipe strap110can comprise more or fewer of the mounting fasteners126.

As shown, each of the mounting fasteners126can be a hex head set screw228comprising a hexagonal screw head230and a threaded screw shaft232extending from the hexagonal screw head230. In other aspects, the brace clamps130can be coupled to the pipe strap110by any other suitable fastener or fastening technique known in the art, including rivets, welds, and the like. Each of the first and second strap mounts124a,bcan define a pair of a strap mounting holes234formed therethrough, and the threaded screw shaft232of a corresponding one of the set screws can extend through each of the strap mounting holes234. Each hexagonal screw head230can abut a lower mount surface236of the corresponding strap mount124, and the corresponding brace clamp130(shown inFIG.1) can be supported on an upper mount surface238of the strap mount124. In some aspects, the strap mounting holes234and/or clamp130mounting holes can be threaded, while in other aspects, the strap mounting holes234and/or clamp mounting holes130may not be threaded.

FIG.3illustrates the lower jaw134of one of the brace clamps130, according to an example aspect. The lower jaw134can define a first jaw side310, a second jaw side312opposite the first jaw side310, a front jaw end314, and a rear jaw end316opposite the front jaw end314. Furthermore, the lower jaw134can comprise a base320and a pair of jaw sidewalls334extending upward from the base320relative to the orientation shown. A first one of the jaw sidewalls334can extend from the base320at the first jaw side310, and a second one of the jaw sidewalls334can extend from the base320at the second jaw side312. Each of the jaw sidewalls334can define a lower hinge opening336extending laterally therethrough, proximate to the rear jaw end316. In example aspects, either or both of the lower hinge openings336can be threaded, though in other aspects, either or both the lower hinge openings336can be unthreaded. The lower hinge openings336can be laterally aligned and can be configured to receive the hinge pin146(shown inFIG.1) therethrough. Furthermore, an upper wall end338of each of the jaw sidewalls334can be curved or angled to define a lower notch340extending downward into the jaw sidewalls334towards the base320. Each of the lower notches340can be configured to receive a portion of the sway pipe830(shown inFIG.8) therein. In other aspects, however, the jaw sidewalls334may not define the lower notches340, and the upper wall end228of each jaw sidewall334can define a substantially flat pipe engagement portion2510(shown inFIG.25). This configuration can allow sway brace pipes830of varying sizes to sit at about the same distance from the suspended piping820when assembled with the sway brace fitting assembly100.

The base320of the lower jaw134can be configured to rest on the upper mount surface238(shown inFIG.2) of the corresponding strap mount124(shown inFIG.1). A pair of clamp mounting holes322can be formed longitudinally through the base320, relative to the orientation shown. The clamp mounting holes322can be disposed between the jaw sidewalls334in example aspects. The clamp mounting holes322can be aligned with the corresponding pair of strap mounting holes234, and each of the clamp mounting holes322can be configured to receive the threaded screw shaft232(shown inFIG.2) of a corresponding one of the set screws (shown inFIG.2) therethrough. In the present aspect, each clamp mounting hole322can be threaded. However, in other aspects, either or both of the clamp mounting holes322may not be threaded.

According to example aspects, a fastener aperture323can be formed through the base320. For example, the fastener aperture323can be a fastener slot324or a threaded fastener hole1810(shown inFIG.18). The fastener slot324formed longitudinally through the base320can be configured to receive the clamp fastener136(shown inFIG.1) therethrough in the engaged configuration. The fastener slot324can extend rearwardly into the base320at the front jaw end314. In the present aspect, the fastener slot324can be elongated and define a closed slot end326distal to the front jaw end314. The closed slot end326can be substantially curved in the present aspect. In other aspects, the fastener slot324may not be elongated, and/or the closed slot end326may not be curved. The fastener slot324can further define an open slot end328opposite the closed slot end326at the front jaw end314of the lower jaw134. In the engaged configuration, a threaded bolt shaft512(shown inFIG.5) of the threaded clamp bolt138(shown inFIG.1) of the clamp fastener136can extend through the fastener slot324, and the clamp nut140(shown inFIG.1) can be tightened against a lower base surface330of the base320. The clamp nut140may be torque sensitive break away nut type or a standard nut type. In other aspects, the brace clamp130may not comprise the clamp nut140, and the fastener slot324of the lower jaw134can be replaced with a threaded opening configured to receive the threaded bolt shaft512therethrough.

Furthermore, in some aspects, the base320can define a pair of positioner tabs332extending downward at the front jaw end314adjacent to (i.e., next to) the fastener slot324. Each positioner tab can be disposed on an opposing side of the fastener slot324. The positioner tabs332can be substantially rounded in the present aspect; for example, the positioner tabs332can be substantially semispherical, as shown. In other aspects, however, the positioner tabs332may not be rounded. According to example aspects, the positioner tabs332can be configured to engage the clamp nut140to prevent the threaded clamp bolt138from sliding out of the fastener slot324through the open slot end328. Other aspects may not comprise the positioner tabs332.

FIG.4illustrates the upper jaw132of one of the brace clamps130(shown inFIG.1), according to an example aspect. The upper jaw132can define a first jaw side410, a second jaw side412opposite the first jaw side410, a front jaw end414, and a rear jaw end416opposite the front jaw end414. In the present aspect, a fastener opening418can be defined longitudinally through the upper jaw132at the front jaw end414. The fastener opening418can be configured to receive the threaded bolt shaft512(shown inFIG.5) of the threaded clamp bolt138(shown inFIG.1) of the clamp fastener136(shown inFIG.1) therethrough. In example aspects, the fastener opening418can define a curved front end419and a curved rear end421, as shown. The curved front and rear ends419,421can allow the threaded clamp bolt138to swing more freely therein and can aid in properly seating the threaded clamp bolt138when it is tightened in the engaged configuration over sway brace pipes830(shown inFIG.8) of varying sizes. In example aspects, a fastener notch420can extend into an upper jaw surface424of the upper jaw132adjacent to (i.e., next to) the fastener opening418at both sides of the fastener opening418. A first one of the fastener notches420can be formed at or near the first jaw side410, and a second one of the fastener notches420can be formed at or near the second jaw side412. According to example aspects, a bolt head510(shown inFIG.5) of the threaded clamp bolt138can engage the fastener notches420, and the fastener notches420can prohibit the threaded clamp bolt138from rotating as the clamp nut140(shown inFIG.1) is being tightened, as well as after the clamp nut140has been tightened.

An upper hinge opening422can be formed laterally through the upper jaw132, proximate to the rear jaw end416. In example aspects, the upper hinge opening422can be threaded, though, in other aspects, the upper hinge opening422can be unthreaded. The upper hinge opening422can be laterally aligned between the lower hinge openings336(shown inFIG.3) of the lower jaw134(shown inFIG.1) and can be configured to receive the hinge pin146(shown inFIG.1) therethrough. Furthermore, in example aspects, the upper jaw132can define a curve(s) or angle(s) between the front jaw end414, and the rear jaw end416, such that a lower jaw surface426of the upper jaw132can define an upper notch440. For example, the upper jaw132can define a first portion442extending substantially upward generally from the front jaw end414or from the fastener opening418to an intermediate point444of the upper jaw132. The upper jaw132can further define a second portion446extending substantially downward generally from the intermediate point444to the lower jaw134end. The upper notch440can generally be defined between the first portion442and the second portion446and can be configured to receive a portion of the sway brace pipe830therein, as described in further detail below.

FIG.5illustrates an example aspect of the brace clamp130in the disengaged configuration. The brace clamp130can comprise the upper jaw132and the lower jaw134. The lower notches340of the lower jaw134can face the upper jaw132, and the upper notch440of the upper jaw132can face the lower jaw134. As shown, the clamp channel142of the brace clamp130can be defined between the lower notches340and the upper notch440. As described above, in the disengaged configuration, the clamp fastener136can be disengaged from the lower jaw134, and the upper jaw132can be pivoted upward and away from the lower jaw134to widen the clamp channel142. The hinge pin146can pivotably couple the upper jaw132to the lower jaw134, such that the upper jaw132can pivot relative to the lower jaw134to adjust the size of the clamp channel142to accommodate sway brace pipes830(shown inFIG.8) of varying sizes and to easily insert the sway brace pipe830therethrough during installation. The hinged connection provided by the hinge145can further allow the brace clamp130to clamp tightly around the sway brace pipe830in the engaged configuration, as shown and described in further detail below with respect toFIG.7.

In example aspects, the hinge pin146can be another one of the hex head set screws228, as shown and described in further detail with respect toFIG.6. In other aspects, the hinge145can comprise a clevis pin, removable rivet, a cast-in hook style hinge, or the like. In the present aspect, the hex head set screw228can threadedly engage the threaded upper hinge opening422(shown inFIG.4) of the upper jaw132and the threaded lower hinge openings336(shown inFIG.3) of the lower jaw134to secure the upper jaw132to the lower jaw134. The threaded connection can provide friction between the hinge pin146and the upper and lower jaws132,134to allow the upper jaw132to remain stationary relative to the lower jaw134in a desired position until a suitable force is applied. For example, for ease of installing the sway brace fitting assembly100(shown inFIG.1) on the sway brace pipe830(shown inFIG.8), it may be desired to temporarily hold the upper jaw132open relative to the lower jaw134(i.e., in the disengaged configuration) to prevent the upper jaw132from rotating towards or away from the lower jaw134.

According to example aspects, the threaded bolt shaft512of the threaded clamp bolt138can extend through the fastener opening418of the upper jaw132. With the upper jaw132pivoted away from the lower jaw134in the disengaged configuration, the threaded bolt shaft512can be disengaged from the fastener slot324of the lower jaw134. The bolt head510of the threaded clamp bolt138can be configured to engage the fastener notches420formed in the upper jaw132. However, in the disengaged configuration, the threaded clamp bolt138can be free to move within the fastener opening418. Thus, the bolt head510may be disengaged from the fastener notches420, as shown, to provide sufficient clearance at the open channel end144for inserting a pre-installed sway brace pipe830(shown inFIG.8) into the clamp channel142through the open channel end144. The clamp nut140can be mounted on the threaded bolt shaft512at or near a distal shaft end514thereof. The distal shaft end514can be oriented opposite a proximal shaft end516of the threaded bolt shaft512. The proximal shaft end516can be connected to the bolt head510.

FIG.6illustrates an example aspect of the hinge pin146, which can be one of the hex head set screws228in the present aspect. In the present aspect, the hex head set screw228of the hinge pin146can be substantially the same as the hex head set screws228of the mounting fasteners126(shown inFIG.2) that are configured to mount the brace clamp130(shown inFIG.1) to the pipe strap110(shown inFIG.1). For example, the hex head set screws228used for both the hinge pin146and the mounting fasteners126can comprise the hexagonal screw head230and the threaded screw shaft232extending from the hexagonal screw head230. As noted above, in other aspects, either or both of the hinge pin146and the mounting fasteners126

FIG.7illustrates the brace clamp130in the engaged configuration. As shown, in the engaged configuration, the upper jaw132can be pivoted at the hinge145downward towards the lower jaw134to narrow the clamp channel142and to engage the threaded bolt shaft512of the clamp bolt138with the fastener slot324of the lower jaw134. As shown, an intermediate portion712of the threaded bolt shaft512between the distal shaft end514and the bolt head510can engage the fastener slot324. As described above, the clamp nut140can be mounted on the threaded bolt shaft512at or near the distal shaft end514, such that the clamp nut140does not interfere with the initial engagement of the threaded bolt shaft512with the fastener slot324. For example, the intermediate portion712of the threaded bolt shaft512can be swung into the fastener slot324through the open slot end328, with the clamp nut140disposed below the open slot end328, relative to the orientation shown. The clamp nut140can then be tightened on the threaded bolt shaft512to abut the lower base surface330of the base320, and the positioner tabs332can engage the clamp nut140to prevent the threaded clamp bolt138from sliding out of the fastener slot324through the open slot end328. In other aspects, the clamp nut140may not be pre-installed on the clamp bolt138, and can be installed thereon after the threaded bolt shaft512has been engaged with the fastener slot324.

FIG.8illustrates the sway brace fitting assembly100partially installed on the sway brace pipe830and coupled to the suspended piping820, in accordance with an example aspect of the present disclosure. As shown, the sway brace fitting assembly100can comprise the pipe strap110and the first and second brace clamps130a,b. The first and second brace clamps130a,bcan be mounted on the corresponding first and second strap mounts124a,b(124ashown inFIG.2) of the pipe strap110. The lower jaw134of each of brace clamp130can be coupled to the corresponding strap mount124by the one or more mounting fasteners126. Each of the mounting fasteners126can engage the corresponding strap mounting hole234(shown inFIG.3) of the pipe strap110and the corresponding clamp mounting hole322(shown inFIG.3) of the brace clamp130. Each brace clamp130can comprise the lower jaw134and the upper jaw132pivotably coupled at the hinge145. The brace clamps130of the present aspect can be substantially the same as the brace clamps130previously shown and described, except the hinge145of the present brace clamps130can be a multi-position hinge810, as shown and described in further detail with respect toFIG.9.

The first brace clamp130ais illustrated in the disengaged configuration, wherein the first brace clamp130ais not coupled to the sway brace pipe830, and as such, the sway brace pipe830is not secured to the sway brace fitting assembly100at the location of the first brace clamp130a. The second brace clamp130bis illustrated in the engaged configured, wherein the second brace clamp130bis coupled to the sway brace pipe830to secure the sway brace pipe830to the sway brace fitting assembly100. In example aspects, the sway brace pipe830can extend beyond either side of the illustrated portion and can be configured to attach to a building structure at a distal end thereof. For example, the sway brace pipe830can be attached to a support beam, a wall, a ceiling, or other suitable support component of the building structure. According to example aspects, a distal end of the sway brace pipe830can be attached to the support component by an I-beam clamp, a wall-mounted bracket, or any other suitable mounting device known in the art. As shown, the sway brace pipe830can be configured to extend across the top side120of the U-shaped strap body115. According to example aspects, the sway brace pipe830can define a substantially tubular shape and can define a substantially cylindrical outer surface832and a substantially cylindrical inner surface834. The brace clamps130can clamp around the outer surface832of the sway brace pipe830in the engaged configuration to secure the sway brace pipe830to the sway brace fitting assembly100. Moreover, the suspended piping820can comprise a system pipe825, which can be held in position by the U-shaped strap body115below the sway brace pipe830, relative to the orientation shown. In example aspects, the suspended pipe825can be oriented about perpendicular to the sway brace pipe830. The suspended pipe825can be part of a piping system (e.g., a water piping system) of the building mechanical system.

Referring to the first brace clamp130ain the disengaged configuration, the upper jaw132can be pivoted away from the lower jaw134at the hinge145to widen the clamp channel142, and the sway brace pipe830can be received through the clamp channel142. Specifically, the sway brace pipe830can be disposed between the upper notch440of the upper jaw132and the lower notches340of the lower jaw134. In the present aspect, the sway brace pipe830can define a relatively small diameter. A clearance can be provided around at least a portion of the sway brace pipe830, such as between the sway brace pipe830and the upper jaw132, as shown, such that the clamp channel142can be configured to accommodate a sway brace pipe830of a larger diameter. The brace clamps130could also accommodate sway brace pipes830of even smaller diameters. According to example aspects, the sway brace pipe830can be inserted laterally through the clamp channel142. In other aspects, such as aspects wherein the sway brace pipe830is pre-installed with the building structure, the sway brace fitting assembly100can be mounted on the pre-installed sway brace pipe830by inserting the sway brace pipe830into the clamp channel142through the open channel end144thereof at the front clamp end150. As shown, in the present aspect, the clamp fastener136can be drawn upward through the fastener opening418of the upper jaw132, away from the lower jaw134, to provide unobstructed access to the clamp channel142through the open channel end144.

Referring to the second brace clamp130bin the engaged configuration, once the sway brace pipe830has been received through the clamp channel142, the upper jaw132can be pivoted towards the lower jaw134at the hinge145to sandwich the sway brace pipe830between the upper jaw132and the lower jaw134, and more specifically, between the upper notch440and the lower notches340. The intermediate portion712of the threaded bolt shaft512can be received through the fastener slot324of the lower jaw134. The clamp nut140disposed on the distal shaft end514of the threaded bolt shaft512can be tightened on the threaded bolt shaft512to abut the lower base surface330of the lower jaw134, and the positioner tabs332can engage the clamp nut140to retain the clamp nut140in position and prevent or limit inadvertent loosening or tightening on the clamp nut140, which can occur due to vibrations. The bolt head510of the threaded bolt shaft512can nest within the corresponding fastener notches420(shown inFIG.4) to prevent rotation of the threaded bolt shaft512as the clamp nut140is tightened thereon. In the present aspect, the fastener notches420can be formed as part of a circumferential fastener recess910(shown inFIG.9) set into the upper jaw surface424. The upper jaw132can be drawn towards the lower jaw134as the clamp nut140is tightened, and the sway brace pipe830can be clamped therebetween. The clamp nut140can be tightened to a suitable torque to properly grip the sway brace pipe830between the upper jaw132and the lower jaw134.

As such, once the sway brace pipe830has been positioned within the clamp channel142, the method for coupling the each of the brace clamps130to the sway brace pipe830can be a quick and easy process comprising just three steps—pivoting the upper jaw132towards the lower jaw134(or vice versa) and coupling the clamp fastener136to the lower jaw134to retain the brace clamp130in the engaged configuration. For example, in the present aspect, coupling the clamp fastener136to the lower jaw134can comprise receiving the clamp fastener136through the fastener slot324and tightening the clamp nut140on the threaded clamp bolt138. To disengage the brace clamp130from the sway brace pipe830, the method can be completed in reverse. That is, the clamp nut140can be loosened, the clamp fastener136can be swung out of the fastener slot324, and the upper jaw132can be pivoted away from the lower jaw134(or vice versa) to widen the clamp channel142. In other aspects, the fastener aperture323can be formed as the threaded fastener hole1810(shown inFIG.18), and coupling the clamp fastener136to the lower jaw134can comprise rotatably engaging the threaded clamp bolt138with the threaded fastener hole1810. An additional benefit, as described above, is that the brace clamps130can be configured to accommodate varying sizes of sway brace pipes830. Furthermore, aspects of the brace clamps130comprising the multi-position hinge810can accommodate an even larger variety of sway brace pipes830.

FIG.9illustrates the sway brace fitting assembly100comprising the multi-position hinge810. As shown, the lower jaw134of each of the brace clamps130can comprise the lower hinge openings336, as described above. In the present aspect, the lower hinge openings336can be a first pair336aof the lower hinge openings336, and the lower jaw134can further comprise a second pair336bof the lower hinge openings336. Like the first pair336aof lower hinge openings336described above, each lower hinge opening336of the second pair336bof lower hinge openings336can be formed through a corresponding one of the jaw sidewalls334. The second pair336bof lower hinge openings336can be disposed above the first pair336aof lower hinge openings336, relative to the orientation shown.

In a first position, the hinge pin146can be received through either the first pair336aof the lower hinge openings336, and in a second position, the hinge pin146can be received through the second pair336bof the lower hinge openings336. The first or second position can be selected based on the size of the sway brace pipe830(shown inFIG.8). For example, the size of the clamp channel142can be reduced when the hinge pin146is received through the first pair336aof the lower hinge openings336. Thus, the brace clamp130can be configured to better accommodate sway brace pipes830of smaller diameters in this configuration. Conversely, the size of the clamp channel142can be increased when the hinge pin146is received through the second pair336bof the lower hinge openings336, and thus, the brace clamp130can be configured to better accommodate sway brace pipes830of larger diameters in this configuration. In other aspects, the lower jaw134can comprise more or fewer pairs of the lower hinge openings336to allow for further adjustability. In other aspects, the upper jaw132can also or alternatively comprise multiple upper hinge openings422(shown inFIG.4) to allow for further adjustability.

FIG.10illustrates one of the brace clamps130according to another example aspect of the present disclosure. As shown, the brace clamp130can comprise the upper jaw132and the lower jaw134. The upper jaw132can be substantially similar to the upper jaw132previously described. For example, the upper jaw132can define the fastener opening418through which the clamp fastener136can be received, the upper hinge opening422(shown inFIG.4) through which the hinge pin146can be received, and the upper notch440partially defining the clamp channel142. The clamp fastener136can be the hex bolt139. The upper jaw132may or may not define the fastener notches420(shown inFIG.4) or the fastener recess910(shown inFIG.9). Moreover, the upper jaw132can be substantially V-shaped in the present aspect. As shown, the upper jaw132can comprise the first portion442and the second portion446disposed at an angle relative to the first portion442to define the upper notch440therebetween. The fastener opening418can be defined through the first portion442proximate to the front jaw end414, and the upper hinge opening422can be defined through the second portion446proximate to the rear jaw end416.

Example aspects of the lower jaw134can also be substantially V-shaped. The lower jaw134can define the base320, which can be considered a first portion1010, and the base320can define the fastener slot324at the front jaw end314. Instead of the jaw sidewalls334(shown inFIG.3), the lower jaw134can define a second portion1012extending substantially rearward and upward from the base320, relative to the orientation shown. The lower notch340can be defined between the base320and the second portion1012of the lower jaw134. A single one of the lower hinge openings336(shown inFIG.11) can be formed through the second portion1012proximate to the rear jaw end316(shown inFIG.11). In some aspects, one or more relief openings1014can be formed through the lower jaw134and/or the upper jaw132to facilitate the lower jaw134and/or the upper jaw132flexing slightly around the sway brace pipe830(shown inFIG.8) in the engaged configuration. For example, a first relief opening1014acan be defined through the lower jaw134at the junction between the base320and the second portion1012, and a second relief opening1014b(shown inFIG.11) can be defined through the lower jaw134between the first relief opening1014aand the fastener slot324.

FIGS.11and12illustrate the lower jaw134and the upper jaw132, respectively. Referring toFIG.11, in example aspects, the lower jaw134can define a nut recess1110set into the lower base surface330and at least partially surrounding the fastener slot324. The nut recess1110can be configured to receive the clamp nut140(shown inFIG.10) therein in the engaged configuration. The nut recess1110can prevent or limit the clamp nut140from rotating on the threaded bolt shaft512(shown inFIG.10) in the engaged configuration and thereby can prevent inadvertent loosening or tightening on the clamp nut140, which can occur due to vibrations.FIG.11also illustrates the first and second relief openings1014a,bformed through the lower jaw134. Referring toFIG.12, in some aspects, the upper jaw132can comprise a pair of fastener positioners1210extending from the lower jaw surface426of the upper jaw132at either side of the fastener opening418. For example, a first one of the fastener positioners1210can be formed at or near the first jaw side410thereof, and a second one of the fastener positioners1210can be formed at or near the second jaw side412thereof.

FIG.13illustrates the brace clamp130comprising the upper jaw132and the lower jaw134, and further comprising the clamp fastener136, wherein the clamp fastener136can be an eye bolt1310. In other aspects, the clamp fastener136can be any other suitable fastener known in the art. The eye bolt1310can comprise a substantially annular eye1312defining a bolt opening1314therethrough and can further comprise the threaded bolt shaft512extending from the annular eye1312. The annular eye1312of the eye bolt1310can be looped through the fastener opening418(shown inFIG.14) of the upper jaw132, such that the front jaw end414can extend through the bolt opening1314. The eye bolt1310can be configured to rotate relative to the upper jaw132about a substantially lateral eye axis1316, which can facilitate swinging the threaded bolt shaft512into the fastener slot324of the lower jaw134through the open slot end328. The fastener positioners1210of the upper jaw132can engage the annular eye1312at either side of the fastener opening418to maintain the alignment of the threaded bolt shaft512with the fastener slot324to further facilitate the engagement of the threaded bolt shaft512therewith. In some aspects, the fastener opening418can be formed as an open-ended upper fastener slot, like the fastener slot324of the lower jaw134, to allow for easy insertion of the annular eye1312therein. In such aspects, a removable upper fastener1318can extend laterally through, or at least partially through, the upper jaw132and across the upper fastener slot, such that the upper fastener1318can be received laterally through the bolt opening1314of the annular eye1312to retain the annular eye1312within the open-ended upper fastener slot. For example, the upper fastener1318can extend through a pair of opposing lateral upper openings1320formed through the upper jaw132and across the upper fastener slot formed therebetween.

FIG.14illustrates the sway brace fitting assembly100in accordance with another aspect of the present disclosure. The sway brace fitting assembly100comprises the first brace clamp130a, the second brace clamp130b, and the pipe strap110. The U-shaped strap body115of the pipe strap110can be configured to restrain the suspended pipe825, and the first brace clamp130aand second brace clamp130bcan be configured to engage the sway brace pipe830. In the present aspect, the first brace clamp130acan be the brace clamp130ofFIG.13comprising the eye bolt1310, and the second brace clamp130bcan be the brace clamp130ofFIG.10comprising the hex bolt139. The first brace clamp130ais illustrated in the disengaged configuration, and the second brace clamp130bis illustrated in the engaged configuration. In other aspects, both of the first and second brace clamps130a,bcan be the brace clamp130ofFIG.10, and in other aspects, both of the first and second brace clamps130a,bcan be the brace clamp130ofFIG.13.

FIG.15illustrates a perspective view of the sway brace fitting assembly100according to another example aspect. The sway brace fitting assembly100can comprise the pipe strap110, the first brace clamp130a, and the second brace clamp130b. In the present view, the first brace clamp130ais oriented in the disengaged configuration (i.e., the open configuration), and the second brace clamp130bis oriented in the engaged configured (i.e., the closed configuration). Each of the first and second brace clamps130a,bcan comprise the upper jaw132, the lower jaw134, and the clamp fastener136. In the present aspect, the clamp nut140mounted on the clamp fastener136can be a flanged torque-off nut1510comprising a flange nut portion1512and a break-off nut portion1514. The break-off nut portion1514can be in the form of a hex nut1516in some aspects, as shown. The break-off nut portion1514can be engaged by a tool, such as a wrench, when tightening the flanged torque-off nut1510on the distal shaft end514of the clamp fastener136, and the break-off nut portion1514can break away from the flange nut portion1512when tightened to a suitable torque. Additionally, in some aspects, a washer1518can be disposed on the threaded bolt shaft512, which can be sandwiched between the clamp nut140and the lower jaw134in the engaged configuration.

Both the upper jaw132and the lower jaw134can be formed from sheet metal in the present aspect. As described above, other aspects of the brace clamps130can comprise any other suitable material. The upper jaw132can be pivotably coupled to the lower jaw134by the hinge145. In the present aspect, the hinge145can be the multi-position hinge810. The lower hinge openings336can comprise the first pair336aand the second pair336bof the lower hinge openings336, and the upper hinge openings422can comprise a first pair422aand a second pair422bof the upper hinge openings422.

Example aspects of the hinge145can comprise the hinge pin146. In the present aspect, the hinge pin146can comprise a clevis pin1520, which can be secured in position by a cotter pin1530. The clevis pin1520can extend through a corresponding pair of the lower hinge openings336and a corresponding pair of the upper hinge openings422. A pin head1522of the clevis pin1520can be sized to prohibit the pin head1522from passing through the lower hinge openings336and the upper hinge openings422in a first direction. The cotter pin1530can be coupled to the clevis pin1520at a distal pin end1524thereof, opposite the pin head1522, and the cotter pin1530can prevent the distal pin end1524of the clevis pin1520from passing through the lower hinge openings336and the upper hinge openings422in an opposite second direction. The clevis pin1520can thereby be secured to the corresponding brace clamp130. In some aspects, the clevis pin1520can engage the cotter pin1530at a middle bump (generally at1530) thereof.

FIG.16illustrates an example aspect of the lower jaw134. The lower jaw134can comprise the base320and the pair of jaw sidewalls334extending upward from the base320relative to the orientation shown. The base320can define the fastener aperture323, which can be the fastener slot324in the present aspect. A first one of the jaw sidewalls334can extend from the base320at the first jaw side310, and a second one of the jaw sidewalls334can extend from the base320at the second jaw side312. The jaw sidewalls334can define the first pair336aand the second pair336bthe lower hinge openings336. The upper wall end338of each jaw sidewall334can define an inner wall edge1610and an outer wall edge1612. In the present aspect, each of the jaw sidewalls344can be angled slightly outward and away from one another. Thus, each of the jaw sidewalls can define an angle R relative to the base320that can be greater than 90° (i.e., obtuse). In other aspects, however, the angle R can be about 90°.

FIG.17illustrates the sway brace fitting assembly100being installed on the sway brace pipe830and suspended pipe825. As shown, the sway brace pipe830can be clamped between the upper jaw132and the lower jaw134of each brace clamp130. The lower jaw134can engage the sway brace pipe830at the upper wall end338of the jaw sidewalls344. Due to the outward angle R of each jaw sidewall334relative to the corresponding base320, the inner wall edge1610of each jaw sidewall334can contact and bite into the sway brace pipe830for an improved grip on the sway brace pipe830. Additionally, the outward angle R of each jaw sidewall334can allow for a portion of the lateral load of the sway brace pipe830to be re-directed against the jaw sidewalls334.

FIG.18illustrates one of the brace clamps130in accordance with another aspect of the present disclosure. The brace clamp130can comprise the upper jaw132, the lower jaw134, and the clamp fastener136. In the present aspect, the fastener aperture323formed in the base320of the lower jaw134can be the threaded fastener hole1810. The clamp fastener136can be coupled to the lower jaw134by engaging the distal shaft end514of the threaded bolt shaft512with the threaded fastener hole1810and rotating the threaded bolt shaft512therein to tighten the clamp fastener136in the engaged configuration.

FIG.19illustrates one of the brace clamps130in accordance with another aspect of the present disclosure. The brace clamp130can comprise the upper jaw132, the lower jaw134, and the clamp fastener136. The fastener aperture323formed in the base320of the lower jaw134can be the fastener slot324. In the present aspect, the fastener opening418of the upper jaw132can be a threaded fastener opening1910. The clamp fastener136can be a flanged torque-off bolt1920. Similar to the threaded clamp bolt138(shown inFIG.1) previously described, the flanged torque-off bolt1920can comprise the threaded bolt shaft512and the bolt head510coupled to the threaded bolt shaft512at the proximal shaft end516. However, in the present aspect, the bolt head510can comprise a flange head portion1922and a break-off head portion1924. The break-off head portion1924can be in the form of a hex head1926in some aspects, as shown.

The distal shaft end514of the threaded bolt shaft512can be pre-engaged with the threaded fastener opening1910of the upper jaw132, as shown. The flanged torque-off bolt1920can be coupled to the lower jaw134by swinging the proximal shaft end512into the fastener slot324through the open slot end328and then rotating the threaded bolt shaft512within the threaded fastener opening1910to tighten the flanged torque-off bolt1920in the engaged configuration. To rotate the threaded bolt shaft512within the threaded fastener opening1910, the break-off head portion1924of the bolt head510can be engaged and rotated by a tool, such as a wrench. Once the flanged torque-off bolt1920has been tightened to a suitable torque for properly clamping the brace clamp130around the sway brace pipe830(shown inFIG.8), the break-off head portion1924of the bolt head510can break away from the flange head portion1922of the bolt head510.

FIG.20illustrates the upper jaw132and/or the lower jaw134, in accordance with another example aspect of the present disclosure. That is, the jaw style shown inFIG.20can serve as the upper jaw132, the lower jaw134, or both the upper and lower jaws132,134. In some aspects, the upper jaw132and the lower jaw134can be cast or otherwise manufactured as identical parts. For the sake of simplicity, the jaw shown inFIG.20is described as the upper jaw132, but the same description could alternatively or also apply to the lower jaw134.

The upper jaw132can define the fastener opening418, which can be defined longitudinally through the upper jaw132proximate to the front jaw end414. The circumferential fastener recess910can be set into the upper jaw surface424and can surround the fastener opening418. In example aspects, the fastener recess910can define a first recess shoulder2010proximate to the first jaw side410and a second recess shoulder2212(shown inFIG.22) proximate to the second jaw side412. Each of the first recess shoulder2010and the second recess shoulder2212can be substantially concave in the present aspect. That is, each of the first recess shoulder2010and the second recess shoulder2212can arc downward towards the lower jaw surface426of the upper jaw132. The first and second recess shoulders2010,2212are shown and described in further detail with respect toFIGS.21and22.

In some aspects, the upper jaw132can define a pair of jaw tabs2014extending upward from the upper jaw surface424at the front jaw end414. A first one of the jaw tabs2014can be disposed generally at or adjacent to the first jaw side410, and a second one of the jaw tabs2014can be disposed generally at or adjacent to the second jaw side412. In aspects wherein the orientation of the clamp fastener136is reversed or wherein the present jaw style serves as the lower jaw134, the jaw tabs2014can function as the positioner tabs332to engage the clamp nut140(shown inFIG.1).

The upper jaw132can further define a plurality of the upper hinge openings422proximate to the rear jaw end416. In the present aspect, the plurality of upper hinge openings422can be interconnected in series to define one large hinge aperture2020having a plurality of hinge sections2022, wherein each of the hinge sections2022can correspond to one of the upper hinge openings422. Internal ridges2024can extend into the hinge aperture2020between each of the upper hinge openings422to define the distinct hinge sections2022and to retain the hinge pin146(shown inFIG.1) in the desired upper hinge opening422.

FIG.21illustrates a perspective view of the upper jaw132and/or the lower jaw134in accordance with another example aspect of the present disclosure, andFIG.22is a cross-sectional view of the upper jaw132and/or the lower jaw134taken along line22-22inFIG.21. That is, the jaw style shown inFIGS.21and22can serve as the upper jaw132, the lower jaw134, or both the upper and lower jaws132,134. In some aspects, the upper jaw132and the lower jaw134can be cast or otherwise manufactured as identical parts. For the sake of simplicity, the jaw shown inFIGS.21and22is described as the upper jaw132, but the same description could alternatively or also apply to the lower jaw134.

The upper jaw132of the present aspect can define the substantially concave first recess shoulder2010and the substantially concave second recess shoulder2212(shown inFIG.22). According to example aspects, the first and second recess shoulders2010,2212can be configured to engage the bolt head510(shown inFIG.5) of the threaded clamp bolt138(shown inFIG.1) in the engaged configuration, and the concavity of the first and second recess shoulders2010,2212can help center the bolt head510within fastener recess910and prevent sliding or movement of the bolt head510therein.

FIGS.23and24illustrate top and bottom perspective views, respectively, of the lower jaw134according to another example aspect. Specifically, the lower jaw134of the second brace clamp130b(shown inFIG.1) is illustrated, which can be attached to the second strap mount124bat the second side114of the pipe strap110(110,114, and124bshown inFIG.1). The lower jaw134can comprise the base320and the pair of jaw sidewalls334extending upward from the base320relative to the orientation shown. The base320can define the fastener aperture323at the front jaw end314, which can be the fastener slot324in the present aspect. The jaw sidewalls334can define the first pair336aand the second pair336bthe lower hinge openings336. In the present aspect, the upper wall end338of each jaw sidewall334define a rear notch portion2310of each lower notch340and an upper base surface2314of the base320can define a front notch portion2312of each lower notch340.

Additionally, referring toFIG.24, the lower base surface330of the base320can define a mount positioning groove2410formed therein. The mount positioning groove2410can extend from an inward-facing side2412of the lower jaw134towards an opposite outward-facing side2414of the lower jaw134. The mount positioning groove2410can terminate at a groove stop surface2416proximate to the outward-facing side2414. As shown, the inward-facing side2412can be the first jaw side310, and the outward-facing side2414can be the second jaw side312on the lower jaw134of the second brace clamp130b. However, on the lower jaw134of the first brace clamp130a(shown inFIG.1), the inward-facing side2412can be the second jaw side312and the outward-facing side2414can be the first jaw side310. According to example aspects, the mount positioning groove2410of the lower jaw134can be configured to receive the corresponding strap mount124(shown inFIG.1) therein. An outward end1540(shown inFIG.15) of the strap mount124can confront (and may abut) the groove stop surface2416. The mount positioning groove2410can correctly position the brace clamp130on the corresponding strap mount124to locate the clamp mounting holes322of the lower jaw134in alignment with the strap mounting holes234(shown inFIG.2) of the strap mount124.

FIG.25illustrates the lower jaw134according to another aspect of the present disclosure. In the present aspect, instead of defining the lower notch340(shown inFIG.3), the upper wall end338of each jaw sidewall334can define the substantially flat pipe engagement portion2510configured to engage the sway brace pipe830(shown inFIG.8) in the engaged configuration. This substantially flap pipe engagement portions2510can allow sway brace pipes830of varying sizes (e.g., varying diameters) to sit at about the same distance from the suspended piping820(shown inFIG.8). For example, a sway brace pipe830having a 1″ diameter can sit at about the same distance from the suspended piping820as a sway brace pipe830having a 2″ diameter.
