Abstract:
Devices, apparatus, systems and methods of installing one-piece sleeve assemblies corrugated decks in floors that are used for plumbing, mechanical, electrical and miscellaneous pipe applications, against water, fire and smoke. A one-piece sleeve assembly combines a resilient sealing member with perimeter extending side walls extending from a central opening that gets poured in place during the concrete pour on the corrugated deck that forms a water, fire and smoke sealed opening about the resilient sealing member and also allows for expansion and contraction of the concrete that surrounds the resilient member, a deck base having outwardly extending wings about a central opening that is aligned with the central opening of the resilient member, and clipped fire stop material that encircles a portion of the central opening of the deck base. The one piece sleeve assembly is installed in a cut out opening the corrugated deck floor so that concrete can then be poured onto the deck about the one-piece assembly. A pipe positioned through the one piece sleeve assembly is sealed in place, by that positioning, so that an outer perimeter of the pipe is sealed against allowing water, smoke and fire to pass around the pipe through the floor and allowing for expansion and contraction of the pipe that passes through the device, and fire and smoke is further prevented from passing about the outer perimeter by the fire stop material which expands from heat.

Description:
This invention relates to sleeving systems for openings in floors and walls, in particular to cast in place devices, apparatus, systems and methods of installation for sealing concrete floors poured over corrugated metal decks that are used for plumbing, mechanical, electrical and miscellaneous pipe applications, that seal against water, fire and smoke within the device after the pipe is passed through the device. 
     BACKGROUND AND PRIOR ART 
     Concrete floors overlaying corrugated metal decking are increasingly popular in multi-story commercial buildings and condominium buildings. In the past it has been known to extend piping systems through concrete floors by knocking out holes in the floor and boring such holes after the floor has been formed, and then extending pipes through the floors. After the pipes have been inserted into the holes, workman have had to pour additional material such as more concrete or other caulking material to seal up the spaces between the voids and the pipes extending through the voids. However, such attempts to use concrete or caulk to seal up the spaces has not been effective to future problems down the road such as from water leaks and fires and smoke that travel through any void spaces between the floors. 
     Any water leaks caused by overflowing waterlines, leaks, broken water lines, etc., flow downward around any openings through the flooring that is around pipes. Such water leaks are known to cause damages to the ceiling and rooms beneath the floor where the openings are around the pipes. This problem becomes compounded in high rises having multiple penetrations on each floor, where large amounts of damage often results in costly repairs and exasperation, and downtime for the occupants. Furthermore, constant leaks have been known to cause health hazards since undesirable and dangerous mold and bacteria will form around the leak areas. 
     Still furthermore, the crevices and cracks about the piping systems in the floors are also a conduit for fires and smoke traveling upward through a multi-floor building. Again, current sealing techniques that have included concrete and/caulk do not effectively seal these void spaces. In fact, over time natural drying effects and typical pipe movement (thermal expansion and contraction) may shrink any caulk seals which results in opening of the crevices and voids about the plumbing systems causing a pathway for fires and smoke to travel through the floors of the buildings about the plumbing systems. 
     Over the years various types of systems and devices have been attempted for trying to fix these sealing issues. See for example, U.S. Pat. Nos. 2,985,091 to Hatcher; 5,293,724 to Cornwall; 6,314,692 to Munzenberger et al.; 6,405,502 to Cornwall; 6,643,985 to Munzenberger; 6,694,684 and 7,080,486 to Radke et al., and devices sold by 3M and Hilti Corporation. 
     Specifically, the 3M devices entitled: 3M Fire Barrier Cast-In Devices and Hilti Corporation devices entitled: Cast-In Firestop devices have been sold for use over metal decks. However, these devices and the others have many problems of their own. For example, the 3M devices and Hilti Corp. devices require many installation steps that are both time consuming and costly in labor to install their devices, as well as many accessory items. In high rises having thousands of openings, the costs for these multiple installation steps can add extra labor costs and time delays that seriously affect these large building projects. 
     Furthermore, these devices require extra setup and finish time that include extra steps for cleaning and cutting that add additional labor and time delay costs. The multitude of installation steps increases the chances for mistakes in the installation process. Again, buildings having thousands of openings that need to be sealed with devices that require a multiple amount of installation and assembly steps increases the chances for mistakes in installing these devices in many of the floor openings. Many of these devices also when installed do not fully waterproof the entire floor openings on the inside and outside. 
     In addition to all of these extra steps, the individual products that are needed come in separate packages and the contractor must carry them all over the project and figure out where they all go. 
     Still furthermore, the 3M and Hilti devices require large amounts of materials to be used since the devices come in many parts that must be assembled together and installed. The costs multiply with multi-story buildings and condominiums having thousands or more of floor openings that need to be sealed. 
     Still furthermore, none of these devices is an effective complete seal against water leaks, fire and smoke passage in concrete floors having corrugated decks since the concrete shrinks, over time leaving a path for water and smoke at the intersection of the sleeve and the concrete. None of these techniques and devices described above solves all the problems addressed above. 
     Thus, the need exists for solutions to the above problems with the prior art.

Small through-holes  415  are used for securing the wings  410 ,  420  to the surface  12  of the corrugated deck  410  with screws. 
     The strengthening ribs  412 ,  418 ,  422 ,  428  make the wings sturdy so that the wings  410 ,  420  will not bend up or down more than a few degrees, and will allow the one-piece sleeve assembly  1  to be secure and to effectively seal in place when the concrete  40  is poured on the corrugated deck  10  around the device. 
     Deck wing base can include a small diameter upper cylinder ring  430  with top edge  432  protruding upwardly from the wings  410 ,  420 , and a large diameter lower cylinder ring  440  with lower bottom edge  448 . A series of slot openings  450  allows for the upper ends  512  of the upwardly protruding prongs  510  of the fire ring clip  500  to pass therethrough and be bent back to hold the fire stop material  600  as is described below. 
     Referring to  FIGS. 1-3 ,  7  and  7 A, the wings  410 ,  420  of the deck wing base  400  overlays the raised surfaces  12  of the corrugated deck  10  on both sides of the deck wing base  400  when the one-piece assembly is positioned over the opening  20  in the corrugated deck  10  so that the large diameter cylindrical ring  440  extends below the corrugated deck  10 . The wings  410 ,  420  have a long enough length to overlay the length of the lower surface valleys  14  of the corrugated deck  10 . Each deck wing  410 ,  420  has a length (approximately 14″ end to end) longer than the width of the lower surface valleys  14 . The sturdiness of the deck wing base  400  allows for an effective seal with the corrugated deck  10  when the concrete  40  is poured in place.

Through-holes  535  are in the bottom base of the fire ring  530 , the latter of which can support and hold the fire stop material  600  in place. 
     Referring to  FIGS. 1-3 ,  7 ,  7 A,  8  and  8 A, the fire stop material  600  is positioned to rest on the bottom base of fire ring  530  between the inner tabs  520  and the outer prongs  510 . Next, the upper ends  512  of the outer prongs  510  are inserted through the slot openings  450  of in the deck base  400 . The upper ends  512  of the prongs  510  are than bent outward as shown in  FIG. 1  to attach the fire ring clip  500  to the deck base  400  and hold the fire stop material/wrap in a cylindrical orientation about the pass through pipe  50 . As previously described, heat causes the fire stop material/wrap  600  to expand which will further cause a seal between the outer walls of pipe  50  and also help collapse the nonmetallic pipe when it starts to melt from the fire and heat, and fill the void around metallic pipe and the upper ring  430  of deck base  400  forming another seal against smoke and fire that could pass between the pipe  50  and the opening  20  in the corrugated deck floor  10 . 
       FIG. 9  is a flowchart  900  of the three basic assembly steps for installing the novel one-piece sleeve into a corrugated floor deck. The steps can include determining the slab thickness of the concrete floor, Step  1 ( 910 ), cutting an opening in the corrugated deck, Step  2 ( 920 ), and the final step of installing the one-piece sleeve assembly  1 , Step  3 ( 930 ). 
       FIG. 10A  is an upper left perspective view of another corrugated deck wing base  460 .  FIG. 10B  is an upper right perspective view of the corrugated deck wing base  460  of  FIG. 10A .  FIG. 10C  is a top view of the corrugated deck wing base  460  of  FIGS. 10A-10B .  FIG. 10D  is an end cross-sectional view of the corrugated deck wing base  460  of  FIG. 10C  along arrow  10 D.  FIG. 10E  is a side cross-sectional view of the corrugated deck wing base  460  of  FIG. 10C  along arrow  10 E. 
     Referring to  FIGS. 1-10E , another version of the corrugated deck wing base  460  can be substituted for the deck wing base  400  previously described. Both deck wing bases  400 ,  460  have the similar components with the exception that deck wing base  460  includes extra strengthening ridges/ribs  470  running about the perimeter of the wings, and the crossed parallel raised ridges./ribs  480 ,  490  define rectangular sections that also can aid in further strengthening of the wings. Deck wing base  460  can be used with the installation method steps and assembled one-piece device  1  that was previously described.

     This comparison shows that it takes four steps to install our device and 17 to install the Hilti device. If each step costs one dollar, figuring a $60 per hour labor rate, (many steps cost more, such as cleaning the opening and cutting the device, which could require as much as five minutes) the Hilti device cost $23 and Presealed Systems, Hydroflame deck device cost $17. The Hilti device is still not water proof on the outside. In addition to all of these steps, the contractor must carry them all over the project and figure out where they go. 
     This also compares favorably to core drilling a hole in the finished floor for $50 and firestopping the opening for $15, after the installation of the pipe. After the installation of the caulk, the W-Rating does not become effective until a full 28 day cure. This comparison is true for all pipe sizes up to 1½″. 80% of all piping sold is 2″ and below. So it figures that the above system is used a lot. If watertight is required by the specifications or by the owner it is an issue. If the contractor wants to provide water tight it is an issue. If everyone is trying to do everything as cheap as possible and as little as possible they will avoid providing a water seal.

     Referring to Table 2, this comparison shows that it takes four steps to install our device and 16 to install the 3M device. If each step costs one dollar, figuring a $60 per hour labor rate, (many steps cost more, such as cleaning the opening and cutting the device, which could require as much as five minutes) the 3M device cost $27 and Presealed Systems, Hydroflame deck device cost $17. The 3M device is still not water proof on the outside. In addition to all of these steps, the contractor must carry them all over the project and figure out where they go. This also compares favorably to core drilling a hole in the finished floor for $50 and fire stopping the opening for $15, after the installation of the pipe. 
     After the installation of the caulk, the W-Rating does not become effective until a full 28 day cure. This comparison is true for all pipe sizes up to 1½″. 80% of all piping sold is 2″ and below. So it figures that the above system is used a lot. 
     Tables 3 and 4 shows comparisons of the labor costs between the invention (Presealed Systems) and a Prior Art system (Hilti system and 3M systems described in the background of the subject invention
