     DETAILED DESCRIPTION 
     Disclosed herein are embodiments of a floor panel seating assembly and brackets and/or guides for seating (e.g., guiding/positioning) a floor panel during construction of a building. The floor panel seating assembly can make it easier, faster, and safer to land floor panels in their desired positions. The guides can be removable and reusable within a single job and over the course of multiple jobs. The floor panel seating assembly can advantageously accommodate different support structure configurations (including different sized top plates of walls) and different sized floor panels due to the adjustability of the guides. The guides can allow for more consistent alignment of floor panels and can allow for installation of the floor panels to be carried out from the interior of the structure, which makes the process of installing floor panels safer. The floor panel seating assembly, hoisted by a crane, can desirably support loads of at least 1,000 lbs, or 2,500 lbs, or 3,000 lbs. The floor panel seating assembly can be moved at a speed of least 2 ft/s, or 3 ft/s, or 4 ft/s. The resulting load can be between 4 kN-8 kN. 
     Also disclosed herein are embodiments of a method of positioning and seating a floor panel during construction. Desirably, the method incorporates using a bracket/guide, or a combination of brackets/guides, to guide and seat a floor panel during construction of a building. The method of using the bracket(s)/guide(s) to guide and seat a floor panel during construction of a building described herein desirably can increase the degree of accuracy/precision in positioning the floor panel and reduce the likelihood of error in positioning the bracket(s)/guide(s) and/or seating the floor panel. 
     The placement of the bracket(s) desirably can be easily modified. The bracket(s) desirably can be removable and/or are not fixed relative to other brackets/guides. The bracket(s) desirably can be reusable. For example, the bracket(s) desirably can be used to guide a particular floor panel into position, removed, then reused to guide another floor panel into position. 
     The structure of the bracket(s) desirably can make bracket installation easier and faster. For example, a driver adjuster desirably can make bracket installation faster than tightening/adjusting brackets by hand. 
     The method desirably can make it easier and faster to position a floor panel. The method desirably can be a “drop and go” approach to seating floor panels. Without using the bracket(s) described herein to guide a floor panel into place, it can take 15 minutes on average (e.g., between 10-20 minutes) to place a floor panel using a single crane, a signal worker, and a team of six installers manually guiding the floor panels. Using the bracket(s) described herein to guide a floor panel into place, it can take 4 minutes on average to place a floor panel (e.g., between 3-9 minutes). The floor panel seating assembly makes it possible to lay at least 3,000-4,500 ft 2  of floor panels in a given day using a single crane, a signal worker, and a team of two installers guiding the floor panels. 
     Installation of the brackets and installation of the floor panels is often safer when using the bracket(s) and method described herein rather than guiding floor panels into position solely by hand (without hardware). For example, desirably the user can maintain his or her center of gravity on the center of a ladder during installation of the brackets. Floor panel installation can also be safer because the brackets desirably secure the floor panels in place and prevent shifting of the floor panels during mounting. 
     The method desirably can include the following steps, in no particular order: 
     Provide an assembled floor panel ( FIG. 21 ) 
     Locate the desired position on the support structure for the floor panel 
     Mount bracket(s) in desired position(s) to the support structure ( FIGS. 17-19 ) 
     (Optionally) Mount bracket(s) in desired position(s) on a second end of the support structure ( FIG. 25 ) 
     (Optionally) Mount bracket(s) in desired position(s) on a third end of the support structure 
     The method desirably can include providing a removable bracket, adjusting the bracket to accommodate different joist/wall/rim sizes, mounting the bracket in position, and lowering an assembled floor panel such that the outer perimeter of the floor panel aligns with the bracket (e.g., aligns with an inner surface of the bracket). 
       FIG. 1  illustrates a floor panel seating assembly  100  mounted on a support structure  250 . In some embodiments, the floor panel seating assembly  100  includes the support structure  250 . As illustrated, a portion of the support structure  250  may include an outer wall  230 , including vertically extending studs  210  and a top plate  200 , such as the double top plate shown ( FIG. 1 ). The top plate  200  can be the top horizontal member(s) of external and internal bearing walls. The top plate  200  can define an upper surface  202 , a bottom surface  203 , and an outer surface  204  ( FIG. 1 ). 
       FIG. 2A  illustrates a floor panel  300  seated on top of a pair of top plates  200 ,  200  of walls of a support structure  250 . The floor panel  300  can include a plurality of cross-members  302 , a plurality of joists  304  extending between the cross-members  302 , and an upper sheet  301  extending over the cross-members  302  and joists  304  (only a portion of the upper sheet  301  being shown in  FIG. 2A  for purposes of illustrating other features beneath the upper sheet  301 ). As illustrated, in some embodiments, a portion of the cross-member  302  can extend beyond the outermost joist  304  on at least one side of the floor panel  300 . As indicated in  FIG. 2A , depending on what is compatible with the relevant portion of the support structure  250 , the outermost support member of the floor panel  300  can be a cross-member  302  or a joist  304 . Generally speaking a rim is supported along its entire length whereas a portion, often substantially the entire length (i.e., at least  90 % of the length), of a joist is unsupported from beneath, spanning between supported portions of the floor panel. In some embodiments, the floor panels could have other configurations and those of skill in the art will appreciate that aspects of the disclosed apparatus and methods could still provide some advantages. 
     The floor panel seating assembly  100  can include a variety of brackets and guides. For example, the floor panel seating assembly  100  can include a combination of one or more rim guide assemblies  400  ( FIG. 29 ), joist guides  500  ( FIG. 19 ), and/or ledger guides  800  ( FIG. 39 ), each of which will be described in greater detail below.  FIG. 2B  illustrates a top view of an example floor plan, which shows possible positions for mounting one or more rim guide assemblies  400 , joist guides  500 , and/or ledger guides  800  to a support structure  250 . As shown in  FIG. 2A  and in the lower left-hand corner of the floor plan of  FIG. 2B , in some instances, a rim guide assembly  400  and a joist guide  500  are mounted adjacent to one another along the length of the same top plate  200 . As shown in  FIG. 2A  and in the lower right-hand corner of the floor plan of  FIG. 2B , in some instances, a rim guide assembly  400  and a joist guide  500  are mounted to different, spaced apart top plates  200  of walls. 
     The rim guide assembly  400  can be configured to attach to a top plate  200  of a wall and to guide a cross-member of a floor panel into place. Portions of the rim guide assembly  400  can be adjustable to accommodate different wall plates (e.g., different wall plate widths) and/or floor cross-member (e.g., different floor cross-member widths). For example, a portion of the rim guide assembly  400  can be configured to slide to accommodate different widths of wood, such as floor panel  300 , on top of a support structure  250 . The joist guide  500  can be configured to attach to a top plate  200  of a wall and to guide a joist of a floor panel into place. Portions of the joist guide  500  can be adjustable to accomodate different floor joist sizes. The adjustability of the rim guide assembly  400  and/or joist guide  500  allows the guides to accommodate various support structure configurations and various floor panel configurations. 
     The bracket(s) desirably can include an angled segment (e.g., a portion bent at an angle with respect to a vertical portion) such that when the floor panel is lowered, a wider aperture is available to guide the floor panel into place. The floor panel desirably can be lowered along an outer face of the angled segment of the bracket. This desirably can allow for increased visibility of the floor panel as it is being positioned.

The macro adjustment can be applied in increments of less than 4″, or 2″, or 1.5″. The macro adjustment may be selected to correspond to a distance that is slightly larger than the expected width of the wall  230 . 
     The fine adjustment can be at least 1/10″, or ⅛″, or ¼″. The fine adjustment can be less than 2.5″, or 1″, or ½″. The fine adjustment can be applied in increments of at least 1/10″, or ⅛″, or ¼″. The fine adjustment may be selected to more precisely correspond to the width of the wall  230 . 
     The distance between the arm  412  and the support  424  can be adjusted (e.g., the distance can be at least 3″, or 4″, or 5″, or the distance can be less than 10″, or 8″, or 6″). As illustrated in  FIG. 7 , the support  424  can move along paths A and/or B. The support  424  can be movable along a track  420 , towards and/or away from the arm  412  along path A. The main body  402  can include fasteners  421  to secure the relative positions of the arm  412  and the support  424  along path A. As illustrated in  FIG. 6 , the fasteners  421  can be pins that can slide into spaced apart apertures in the horizontal section  410  of the main body  402 , where the apertures define distances at which the support  424  can be secured relative to the arm  412  along path A. The positions of the apertures may correspond to distances that are slightly larger than common widths of walls to allow for convenient macro adjustments of the rim guide assembly  400 . 
     The position of the support  424  can be adjusted along path B by rotating a fastener, such as a bolt  422 , that is coupled to the support  424 . In some embodiments, use of the fasteners  421  prevents movement of the support  424  along path A but does not inhibit movement of the support  424  along path B. 
     The lower portion of the arm  412  can define a first support structure clamping surface  416 . The first support structure clamping surface  416  can abut (e.g., grip) the outer surface  204  of the top plate  200 . The upper portion of the arm  412  can define a first guide surface  414  and an angled surface  418 . The first guide surface  414  can help guide a cross-member of a floor panel into position. The angled surface  418  can advantageously reduce the risk that the arm  412  will interfere with or block the cross-member of the floor panel, or otherwise make it more difficult to lower the floor panel into place. 
     A portion of the main body  402  can be compatible with, and configured to coupled to, a portion of the mount body  404 . For example, the support  424  can include a projection configured to be received in a portion of the mount body  404  (e.g., a slot or channel), or the support  424  can include an opening configured to receive a projection on the mount body  404 . The support  424  can include a safety  426  that prevents inadvertent disassembling of the mount body  404  from the main body  402  when loosening the bolt  422  and/or prevents unnecessary wear to components of the rim guide assembly  400  when tightening the bolt  422 . In some embodiments, tightening the bolt  422  of the main body  402  tightens the mount body  404  to the main body  402  when the mount body  404  is coupled to the main body  402 . 
     Mount Body 
     As shown in  FIGS. 9-12 , the second portion or mount body  404  can include a vertical segment and an angled segment. As shown in  FIGS. 9-12 , the mount body  404  can include a horizontal section  440 , an upwardly extending section or arm  442 , and/or a downwardly extending section or arm  450 . The mount body  404  can be adjusted to accommodate different configurations of floor panels (e.g., floor panels of different heights and widths). For example, as illustrated by the arrow H shown in  FIG. 5 , the height of the rim guide assembly  400  can be adjusted. The relative positions of the main body  402  and mount body  404  can be adjustable. For example, the mount body  404  can be moved up and down relative to the base of the main body  402  along a vertical axis and/or the main body  402  can be moved up and down relative to the mount body  404  along the vertical axis. 
     The mount body  404  can be adjusted to accommodate different sized floor panel cross-member widths, such as floor panel cross-member widths of at least 1.5″, or 2″, or 3″. The mount body  404  can accommodate floor panel cross-member widths of less than 7″, or 5″, or 4″. The upwardly extending arm  442  can move transverse to the downwardly extending arm  450 . For example, as illustrated in  FIGS. 10-11 , the upwardly extending arm  442  and the downwardly extending arm  450  can be aligned along the same vertical plane. As illustrated in  FIGS. 9 and 12 , the upwardly extending arm  442  and the downwardly extending arm  450  can be offset. For example, as shown in  FIG. 9 , the upwardly extending arm  442  can extend transversely beyond the downwardly extending arm  450  (toward the arm  412  when the main body  402  and the mount body  404  are coupled or integral,  FIG. 3 ). 
     Loosening the fastener  456  can allow the horizontal section  440  of the mount body  404  to slide towards and away from the arm  412  of the main body  402 . For example, loosening the fastener  456  can enable the upwardly extending arm  442  to slide transverse to the downwardly extending arm  450  along the longitudinal axis of the mount body  404  (e.g., toward or away from the arm  412  when the first portion or main body  402  and the second portion or mount body  404  are coupled or integral). Tightening the fastener  456  can fix the relative positions of the upwardly extending arm  442  and the downwardly extending arm  450 . The horizontal section  440  and/or the upwardly extending arm  442  can be movable along the longitudinal axis of the mount body  404  by at least 0.01″, or 0.5″, or 1″, or 2″, or 3″ or 4″. The horizontal section  440  and/or the upwardly extending arm  442  can be movable along the longitudinal axis by less than 10″, or 8″, or 5″. 
     As illustrated in  FIGS. 9-12 , the downwardly extending arm  450  can define a second support structure clamping surface  452 . The second support structure clamping surface  452  can abut (e.g., grip) a lateral surface of the top plate  200  (such as the lateral surface of the top plate  200  opposite the outer surface  204 ). The first support structure clamping surface  416  does not need to be located on the first portion or main body  402  and the second support structure clamping surface  452  does not need to be located on the second portion or mount body  404 . For example, in some embodiments, both the first and second support structure clamping surfaces  416 ,  452  can be defined by the main body  402 . 
     As illustrated in  FIG. 9 , the upwardly extending arm  442  can define a second guide surface  444  and an angled surface  446 . In some embodiments, as illustrated in  FIG. 12 , the upwardly extending arm  442  can define a second guide surface  444  and multiple angled surfaces  446 ,  448 . The second guide surface  444  can help guide a cross-member of a floor panel into position. The angled surface(s)  446 ,  448  can reduce the risk that the upwardly extending arm  442  will interfere with or block the cross-member of the floor panel, or otherwise make it more difficult to lower the floor panel into place. 
     A portion of the mount body  404  can be compatible with, and configured to couple to, a portion of the main body  402 . For example, the downwardly extending arm  450  can include a mating feature, such as a slot  454  (as shown in  FIG. 9 ) or a protrusion that can couple to a corresponding mating feature on the main body  402 , such as a protrusion or a slot, respectively. 
     Joist Guide 
       FIGS. 13-16  illustrate embodiments of a joist guide  500 ,  500 ′. The features of the joist guide  500 ′ shown in  FIGS. 15-16  are the same as those described with respect to the joist guide  500  shown in  FIGS. 13-14 , except that the features of the joist guide  500 ′ face in the opposite direction from the features of the joist guide  500 . 
     The joist guide  500  can include a first segment  502 , a second segment  504 , a mounting flange  506 , and/or a bottom alignment guide  508 . The space between the first segment  502  and the second segment  504  can define an opening  520  configured to receive a joist of a floor panel. The joist guide  500  can be adjusted to accommodate floor panel joists of different widths, such as joist widths of at least 1″, or 2″, or 3″, or 4″, or 5″, or 6″ or 8″. The joist guide  500  can be adjusted to accommodate joist widths of less than 5″, or 4″, or 3.5″. For example, as illustrated in  FIG. 14 , the second segment  504  can be moved relative to the first segment  502  (e.g., the second segment  504  can be moved towards and/or away from the first segment  502 ). The second segment  504  can be spaced a distance C (as shown in  FIG. 14 ) from the first segment  502  of at least 0.5″, or 1″, or 1.5″. The second segment  504  can be spaced a distance C from the first segment  502  of less than 6″, or 5″, or 4″. 
     The first segment  502  of the joist guide  500  can define a first guide surface  522  and an angled surface  524 . The first guide surface  522  can help guide a joist of a floor panel into position. The angled surface  524  can reduce the risk that the first segment  502  will interfere with or block the joist of the floor panel, or otherwise make it more difficult to lower the joist into place. 
     The second segment  504  of the joist guide  500  can define a second guide surface  526  and angled surface(s)  528 ,  529 . The second guide surface  526  can help guide a joist of a floor panel into position. The angled surface(s)  528 ,  529  can reduce the risk that the second segment  504  will interfere with or block the joist of the floor panel, or otherwise make it more difficult to lower the joist into place. 
     The first segment  502  can extend higher (e.g., vertically) than the second segment  504 . That is, the top of the first segment  502  can be a greater vertical distance from the bottom alignment guide than the second segment  504 . The taller of the two segments  502 ,  504  can be disposed on the outer side of the joist guide  500  and the shorter of the two segments  502 ,  504  can be disposed on the inner side of the joist guide  500 . The joist guide  500  can include a reinforcement  510  along the outer side of the joist guide  500  (e.g., along the external-facing side of the first segment  502  as shown in  FIG. 13 ). The taller segment, the first segment  502 , can help direct the joist of the floor panel, and the reinforcement  510  can provide additional support (e.g., to prevent damage to the joist guide  500 ). The shorter segment, the second segment  504 , can help position the joist of the floor panel while maintaining a low enough profile so as to reduce the risk of blocking, or otherwise interfering with, the joist. 
     The mounting flange  506  can be used to mount the joist guide  500  to a support structure  250 . For example, fasteners, such as lags, bolts, and/or screws, can be inserted through apertures in the mounting flange  506  and into a lateral side of a top plate  200 . The mounting flange  506  can extend below the upper surface  202  of the top plate  200 . 
     The bottom alignment guide  508  can be configured to receive a joist of a floor panel. In some embodiments, the bottom alignment guide can include at least three points which define an upper plane against which to position the bottom surface of a joist. The joist guide  500  can be mounted on the support structure  250  such that the upper surface of the bottom alignment guide  508  is aligned with (e.g., positioned along the same horizontal plane as) the upper surface  202  of the top plate  200  of the wall. This can advantageously allow for a bottom surface of a joist to lay flat on the upper surface  202  of the top plate  200  of the wall and the upper surface of the bottom alignment guide  508  of the joist guide  500 . 
     Loosening the fastener  512  can enable the second segment  504  to slide relative to the first segment  502 . For example, loosening the fastener  512  can permit surface  522  to move toward or away from surface  526 . Tightening the fastener  512  can fix the relative positions of the first segment  502  and the second segment  504 . 
     Method of Using Rim Guide Assembly and/or Joist Guide to Seat a Floor Panel 
     The method of using one or more rim guide assembly  400  and one or more joist guide  500  to seat a floor panel can include any of the steps outlined below, in any order. 
     The method can include determining a position for a first rim guide assembly  400 . The method can include positioning and clamping a main body  402  of a first rim guide assembly  400  to a first top plate  200  of a support structure  250 , with a first clamping surface  416  flush with an outer surface  204  of the top plate  200 . The method can include making macro adjustments of the rim guide assembly  400  before and/or after clamping the rim guide assembly  400  to the first top plate  200 . The method can include making fine adjustments of the first rim guide assembly  400  to securely clamp the first rim guide assembly  400  to the first top plate  200 . The method can include coupling the mount body  404  to the main body  402  ( FIG. 18 ). The method can include adjusting the spacing between the first guide surface  414  and the second guide surface  444  to correspond to the expected thickness of the cross-member  302  of the floor panel  300 . The method can include determining a position for a second rim guide assembly  400 . The method can include positioning and clamping the second rim guide assembly  400  to the first top plate  200  ( FIGS. 2A, 29 ). The method can include making adjustments to the second rim guide assembly  400  as outlined above with respect to the first rim guide assembly  400 . The method can include determining a position for a first joist guide  500 . The method can include positioning and mounting a first joist guide  500  to a lateral surface of the first top plate  200  ( FIG. 17 ). The method can include adjusting the distance between the first guide surface  522  and the second guide surface  526  of the first joist guide  500  to correspond to the expected thickness of the joist  304  of the floor panel ( FIG. 15 ). The method can include determining a position for a second joist guide. The method can include positioning and mounting the second joist guide  500  to a lateral surface of a second top plate  200  ( FIG. 25 ). The method can include adjusting the distance between the first guide surface  522  and the second guide surface  526  of the second joist guide  500  to correspond to the expected thickness of the joist  304 . 
     The method can include lowering a first floor panel  300  over a support structure ( FIG. 21 ) and dropping the first floor panel  300  into the desired position on the support structure  250  using the first and second rim guide assemblies  400  to guide the cross-member  302  of the floor panel and using the first and second joist guides  500  to guide the joist  304  of the floor panel ( FIG. 2A ,  FIGS. 22-25 ). The joist  304  can desirably be an outermost joist along one side of the floor panel. 
     The method can include positioning the first floor panel  300  such that a portion of the cross-member  302  of the first floor panel  300  extends beyond the outermost joist  304  of the first floor panel. The method can include positioning a second floor panel  300  next to the first floor panel  300  such that the cross-member  302  of the second floor panel  300  abuts the cross-member  302  of the first floor panel. The method can include installing a floor strip in the gap formed between the outermost joists  302  of the first and second floor panels  300 . 
     The method can include removing the first rim guide assembly  400 , second rim guide assembly  400 , first joist guide  500 , and second joist guide  500  from the support structure. 
     A floor plan, such as the one shown in  FIG. 2B , can be generated to map out the desired position (and/or relative positions) of one or more rim guide assembly  400 , joist guide  500 , and/or any other guide/bracket described herein (e.g., L-bracket  600 , elongate bracket  700 , ledger guide  800 ).  FIGS. 1, 17-20, and 22-29  illustrate examples of rim guide assemblies  400  and joist guides  500  positioned on support structures  250 . In some embodiments, as illustrated in  FIG. 17 , the desired position for a rim guide assembly  400  can be adjacent to (but spaced apart from) a joist guide  500 ,  500 ′ along the length of a top plate  200 . As illustrated in  FIG. 18 , the desired position for a rim guide assembly  400  can be a location that is spaced further from (e.g., more isolated from) other guides. As illustrated in  FIG. 19 , the desired position for a joist guide  500  can be adjacent to (but spaced apart from) a joist guide  500 ′ along the length of a top plate  200 . The desired position for a joist guide  500  can be a location that is spaced further from (e.g., more isolated from) other guides ( FIGS. 2A, 25 ). As shown, more than one rim guide assembly  400  can be positioned along the length of the same top plate  200  ( FIG. 29 ), more than one joist guide  500  can be positioned along the length of the same top plate  200  ( FIG. 19 ), a rim guide assembly  400  and/or a joist guide  500  can be positioned along the length of the same top plate  200  ( FIGS. 2A, 17 ). As illustrated in  FIGS. 2A and 24-25 , a rim guide assembly  400  and joist guide  500  can be positioned on different sides of a support structure  250  (such as on top plates  200  that are on opposite portions of a support structure  250  facing one another). 
     In some embodiments, as shown in  FIG. 19 , a first joist guide  500 ′ facing in a first direction and a second joist guide  500  facing in a second direction opposite the first direction can be mounted adjacent, but spaced apart from, one another along the length of a top plate  200 . In the illustrated embodiment, the first joist guide  500 ′ is configured to capture a joist  304  of a first floor panel  300  and the second joist guide  500  is configured to capture a joist  304  of a second floor panel  300 . When the first and second floor panels  300  are installed in their desired positions, a gap can exist between the outermost joists  304  of each floor panel  300  (e.g., the joists  304  captured by the joist guides  500 ′,  500 ). A wood panel can be installed to fill said gap. The gap can advantageously provide tolerance to accommodate for errors that can occur during the installation of floor panels. 
     In some embodiments, as illustrated in  FIG. 20 , a cross-member  302  of a first floor panel  300  can extend laterally beyond the outermost joist  304  of said first floor panel. Although a second floor panel can be positioned next to the first floor panel  300  such that the cross-member  302  of the first floor panel comes close to, or abuts, a cross-member of the second floor panel, a gap can exist between the outermost joists  304  of each floor panel. A wood panel can be installed to fill said gap. The gap can advantageously provide tolerance to accommodate for errors that can occur during the installation of floor panels. 
     Rim guide assemblies  400  and joist guides  500  can be mounted adjacent to one another and/or on opposite sides of a frame structure from one another to provide points of contact to help guide the floor panel  300  into position. Desirably, the floor panel seating assembly  100  can provide more than one (e.g., two, three, four, etc.) point of contact for guiding the floor panel  300 , such as two points of contact for one corner of the floor panel  300  and another point of contact on the side of the floor panel  300  opposite that corner. As shown in  FIGS. 26-28 , the rim guide assemblies  400  can be used to guide (e.g., catch, direct, etc.) the cross-member(s)  302  of a floor panel  300  and the joist guides  500  can be used to guide (e.g., catch, direct, etc.) the joist(s)  304  of the floor panel  300 . 
     As previously described, the rim guide assembly  400  can be adjusted to accommodate different top plate  200  widths and floor panel cross-member  302  widths, and/or the joist guide  500  can be adjusted to accommodate different floor panel joist  304  widths. In some embodiments, the rim guide assembly  400  and/or joist guide  500  can be adjusted to accommodate the size of a given top plate  200  or floor panel  300  before being mounted to the support structure  250 . In some embodiments, the rim guide assembly  400  and/or joist guide  500  can be adjusted to accommodate the size of a given top plate  200  or floor panel  300  after being mounted to the support structure  250 . In some embodiments, some amount of adjustment of the guide(s)  400 ,  500  can occur before mounting the guide(s) to the top plate  200  and some amount of adjustment of the guide(s) can occur after mounting the guide(s) to the top plate  200 . 
     As illustrated in  FIG. 21 , an assembled floor panel  300  can be provided. The floor panel  300  can include cross-member(s)  302  and joist(s)  304 . The floor panel  300  can weigh 500-5,000 lbs, or 2,000-3,000 lbs, or 1,000-3,500 lbs. The floor panel  300  can weigh at least 500 lbs, or 2,000 lbs, or 3,500 lbs. The floor panel  300  can be lowered to a position above a support structure  250  using a crane  900 . As shown in  FIGS. 22-25 , the floor panel  300  can be aligned with one or more rim guide assembly  400  and/or joist guide  500 . Once aligned above the guide(s), the floor panel  300  can be lowered onto the guide(s) and dropped into the desired position. The guide(s) can help direct the floor panel  300  into the desired position, with the rim guide assembly  400  directing a cross-member  302  of the floor panel  300  and the joist guide  500  directing a joist  304  of the floor panel  300 . The cross-member  302  can slide into the opening  460  in the rim guide assembly  400 , the bottom surface of the cross-member  302  contacting the upper surface  202  of the top plate  200  and the outer surface of the cross-member  302  aligning with the outer surface  204  of the top plate  200 . The joist  304  can slide into the opening  520  in the joist guide  500 , the lower surface  305  of the joist  304  contacting the upper surface  202  of the top plate  200  and the upper surface of the bottom alignment guide  508 . The support structure  250  can provide the majority of the support provided to the floor panel  300  once the floor panel  300  is seated on the top plate  200 . 
       FIGS. 22-24  show an example of a floor panel being guided into position by brackets/guides that are mounted on the support structure  250 . Optionally, as illustrated in  FIG. 25 , a bracket(s)/guide(s) may also be mounted on a second end of the support structure  250  (e.g., such that brackets can help guide the floor panel at opposing ends of the floor panel). Desirably, a combination of one or more rim guide assemblies  400  and one or more joist guides  500  can be used in conjunction to seat the floor panel  300 . As shown in  FIGS. 22-25 , a rim guide assembly  400  and a first joist guide  500  can be mounted adjacent to one another along the length of a top plate  200 , and a second joist guide  500  can be mounted to a top plate  200  on the opposite end of the support structure  250  (e.g., parallel to and facing the top plate  200  to which the rim guide assembly  400  and first joist guide  500  are mounted). As shown, the rim guide assembly  400  can catch a cross-member  302  of the floor panel, the first joist guide  500  can catch a joist  304  at a first end of the joist  304  (e.g., the end of the joist  304  closest to said cross-member  302 ), and the second joist guide  500  can catch the joist  304  at a second end of the joist  304  opposite the first end. This arrangement can advantageously increase the speed and accuracy with which the floor panel  300  is seated. 
     The rim guide assembly  400  and/or the joist guide  500  can be removable and reusable. For example, after a given floor panel  300  is seated, the rim guide assemblies  400  and joist guides  500  can be removed from the top plates  200  and mounted to different top plates  200  or support structure(s)  250  for use in positioning another floor panel  300 . 
     L-Bracket 
       FIG. 30  illustrates an embodiment of an L-bracket  600 . The L-bracket  600  can be used by itself or in combination with other guides discussed herein. The L-bracket  600  can desirably be used when there is a solid top plate and there is not space to attach a rim guide assembly  400  to the top plate  200 . For example, the L-bracket  600  can be used on party walls. The L-bracket  600  can be generally L-shaped. The L-bracket  600  can include a first segment  602  and a second segment  604 . The first segment  602  can be perpendicular to the second segment  604 . 
     The first segment  602  can define a guide surface  606  and angled surfaces  608 ,  610 . The angled surfaces  608 ,  610  can be disposed on either end of the first segment  602 . The angled surfaces  608 ,  610  can be angled at  45  degrees relative the guide surface  606 . The second segment  604  can define a first side  612  and a second side  614 . 
       FIGS. 31-34B  illustrate a method of using the L-bracket  600  to guide cross-members  302  of floor panels  300  into the desired positions on a support structure  250 . As shown in  FIG. 32 , the L-bracket  600  can be mounted to (e.g., screwed onto) the upper surface  202  of the top plate  200  with the first side  612  of the second segment  604  in contact with the upper surface  202  of the top plate  200 . A first floor panel  300  can be lowered into the desired position, using the angled surface  608  and/or guide surface  606  of the first segment  602  to guide the cross-member  302  of the first floor panel  300 . As shown in  FIGS. 31 and 34A , once the first floor panel  300  is positioned, the L-bracket  600  can be detached from the upper surface  202  of the top plate  200 , reoriented (e.g., flipped), and secured to the top surface of the cross-member  302 . The L-bracket  600  can be mounted to the cross-member  302 , with the second side  614  of the second segment  604  in contact with the top surface of the cross-member  302  and the interior surface  605  of the first segment  602  in contact with an outer surface of the cross-member  302 . A second floor panel  300  can be lowered into the desired position, using the angled surface  610  and/or guide surface  606  of the first segment  602  to guide the cross-member  302  of the second floor panel  300  ( FIG. 34B ). Once the floor panels  300  are positioned, the L-bracket  600  can be removed. As shown in  FIG. 34B , the L-bracket  600  can preserve a gap  650  between first and second seated floor panels  300 . The gap  650  can be at least 1″, or 2″, or 3″. The gap  650  can be less than 5″, or 4″, or 3″. The gap  650  formed between the first and second seated floor panels  300  can advantageously allow for appropriate sound attenuation for the building being constructed. 
     Elongate Bracket 
       FIG. 35  illustrates an embodiment of an elongate bracket  700 . The elongate bracket  700  can include a guide portion  702  and an angled portion  704 . The angled portion  704  can be angled relative to the guide portion  702 . The elongate bracket  700  can be used by itself or in combination with other guides discussed herein. For example, the elongate bracket  700  can be used in conjunction with a rim guide assembly  400  or a main body  402  of the rim guide assembly  400 . The elongate bracket  700  and the main body  402  can be mounted along the length of the same top plate  200  and/or can be mounted on separate top plates  200  opposite one another. The elongate bracket  700  can desirably be used when there is a solid top plate and wall studs interfere with the use of certain other guide configurations. For example, the elongate bracket  700  can be used to position floor panels  300  near corridors and plumbing walls. 
       FIG. 36  illustrates the elongate bracket  700  mounted on a wall  230 . A lower portion of the guide portion  702  can be mounted to an outer surface of the wall  230 . For example, as shown in  FIG. 36 , the lower portion of the guide portion  702  can be mounted to an outer surface of a wall stud  210  and/or an outer surface of a top plate  200 . The angled portion  704  and the upper portion of the guide portion  702  (e.g., the portion extending above the top plate  200  when the elongate bracket  700  is mounted to the wall  230 ) can guide a cross-member  302  of a floor panel  300  into position such that the outer surface of the cross-member  302  of the floor panel  300  aligns with the outer surface  204  of the top plate  200 . Ledger Guide 
       FIGS. 37-40  illustrate an embodiment of a ledger guide  800  that can be used to guide a ledger  306  of a floor panel  300  into a desired position abutting a beam  240 . As illustrated in  FIG. 38 , the ledger guide  800  can include a horizontal segment  802  and a guide portion  804 . The horizontal segment  802  can define an upwardly facing alignment surface  810  and an upwardly facing mounting surface  812 . The guide portion  804  can define a guide surface  806  and angled surfaces  808 ,  809 . The angled surfaces  808 ,  809  can be angled relative to the guide surface  806  and relative to one another. 
     As shown in  FIG. 39 , one or more ledger guides  800  (or one or more pairs of ledger guides  800 ) can be coupled to the beam  240 . Two or more ledger guides  800  can be coupled to the lower surface  242  of the same beam  240 . The two or more ledger guides  800  can be spaced apart laterally along the length of the beam  240  and/or can be spaced apart by the width of the beam  240 . 
     The ledger guide  800  can be configured to slide under and couple to a lower surface  242  of the beam  240 . The ledger guide  800  can be secured to the beam  240  such that the upwardly facing mounting surface  812  abuts the lower surface  242  of the beam  240  and the upwardly facing alignment surface  810  extends outward from beneath the beam  240 . The gap formed between the outer surface of the beam  240  and the guide portion  804  of the ledger guide  800  can define an opening  820  for receiving a ledger  306  of a floor panel  300 . The ledger guide  800  can accommodate beam  240  of different sizes (such as beams having widths of at least 3.5″, 4″, or 5.5″ and beams having widths less than 15″, or 10″, or 7″). The ledger guide  800  can extend at least 1″, or 1.5″, or 3″ beneath the beam  240 . The ledger guide  800  can extend less than 12″, or 10″, or 6″ beneath the beam  240 . The ledger guide  800  can extend beneath at least half of the width of the beam  240 . 
     The ledger  306  of the floor panel  300  can be lowered into the opening  820 . The angled surfaces  808 ,  809  and the guide surface  806  of the guide portion  804  can direct the ledger  306  into the desired position. The ledger guide  800  can hold the ledger  306  flush against the outer surface of the beam  240  so that the ledger  306  can be fastened to the beam  240 . 
     Ledger Support 
       FIGS. 41-42  illustrate an embodiment of a ledger support  900 . The ledger support  900  can include a first segment  902  and a second segment  904 . The second segment  904  can be perpendicular to the first segment  902 . The first segment  902  can define apertures  910 . The apertures  910  can be configured to receive fasteners. 
       FIGS. 43-44  illustrate a method of mounting ledger supports  900  to a side surface of a top plate  200  of a wall  230 . The first segment  902  can be mounted to the side surface of the top plate  200  by inserting fasteners through the apertures  910  in the first segment  902  and into the top plate  200 . The second segment  904  can extend laterally away from the side surface of the top plate  200  to which the first segment  902  is mounted. A floor panel  300  can be lowered on top of the ledger supports  900  such that the ledger  306  of the floor panel rests on the upper surface of the second segment  904 . The ledger support  900  can provide temporary support for the floor panel  300  before the floor panel  300  is permanently fixed to the support structure  250 . The ledger support  900  can be removed once the floor panel  300  is fixed to the support structure  250 . 
     From the foregoing description, it will be appreciated that inventive floor panel seating assemblies and methods of seating a floor panel are disclosed.

     Certain features that are described in this disclosure in the context of separate implementations can also be implemented in combination in a single implementation. Conversely, various features that are described in the context of a single implementation can also be implemented in multiple implementations separately or in any suitable subcombination. Moreover, although features may be described above as acting in certain combinations, one or more features from a claimed combination can, in some cases, be excised from the combination, and the combination may be claimed as any subcombination or variation of any subcombination. 
     Moreover, while methods may be depicted in the drawings or described in the specification in a particular order, such methods need not be performed in the particular order shown or in sequential order, and that all methods need not be performed, to achieve desirable results. Other methods that are not depicted or described can be incorporated in the example methods and processes. For example, one or more additional methods can be performed before, after, simultaneously, or between any of the described methods. Further, the methods may be rearranged or reordered in other implementations. Also, the separation of various system components in the implementations described above should not be understood as requiring such separation in all implementations, and it should be understood that the described components and systems can generally be integrated together in a single product or packaged into multiple products. Additionally, other implementations are within the scope of this disclosure. 
     Conditional language, such as “can,” “could,” “might,” or “may,” unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain embodiments include or 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 embodiments. 
     Conjunctive language such as the phrase “at least one of X, Y, and Z,” unless specifically stated otherwise, is otherwise understood with the context as used in general to convey that an item, term, etc. may be either X, Y, or Z.
