DETAILED DESCRIPTION

A floor to wall connector is provided that simplifies the mechanism to connect a wall panel to a floor panel and simplifies the method of connecting a wall panel to a floor panel. The connector can be installed off-site or on-site prior to lifting the wall panel thereby saving time and costs.
FIG. 1 is an exploded view of a floor to wall connector 100. The floor to wall connector 100 is configured to connect a wall panel to a floor panel. The floor to wall connector may be made of metal. More specifically, the floor to wall connector may be made of forged or welded steel. The floor to wall connector 100 includes a wall bracket 200 and a floor bracket 300.
The wall bracket 200 is configured to attach to a wall panel. The wall bracket 200 may be comprised of an L bracket with a first leg 210 and a second leg 220 attached at an approximately 90 degree angle. The first leg 210 is configured to abut the interior side of a wall panel. The first leg 210 may include a plurality of openings 212. The openings 212 receive fasteners, such as screws, to attach the wall bracket 200 to a wall panel. The second leg 220 is configured to extend into the wall panel. The second leg 220 transfers load from the wall bracket 200 and fasteners to the wall panel. The wall bracket 200 includes a floor receiver 230. The floor receiver 230 may be comprised of an L bracket attached to the first leg 210. The wall bracket 200 may also include a bracket stiffener 232. The bracket stiffener 232 is positioned to support the floor receiver 230 and strengthen the joint between the floor receiver 230 and the first leg 210. The floor receiver 230 and the bracket stiffener 232 may be welded to the first leg 210. The floor receiver 230 may include a threaded hole 234 to receive a lifting hook 240. The lifting hook 240 may be an eye bolt. The lifting hook 240 is configured to receive a hoist which allows a crane to lift, place, and hold the wall bracket 200 attached to a wall panel. The lifting hook 240 may screw into the threaded hole 234. The threads allow the lifting hook 240 to be removed after the wall panel attached to the wall bracket 200 is installed and connected to a floor panel. The floor receiver 230 may also include threaded holes 236 to receive height adjustment screws 242. The height adjustment screws 242 may be screwed into and unscrewed in the threaded holes 236 to adjust the wall bracket 200 vertically. The adjustment screws 242 may include lock nuts 244 to lock the adjustment screws 242.
The floor to wall connector 100 also includes a floor bracket 300 configured to connect to a floor panel. The floor bracket 300 may be comprised of an L bracket with a first leg 310 and a second leg 320 attached at an approximately 90 degree angle. The first leg 310 is configured to abut the end of the floor panel that abuts the wall panel. The second leg 320 is configured to abut the top side of a floor panel. The second leg 320 may include a plurality of openings 322. The openings 322 receive fasteners, such as screws, to attach the floor bracket 300 to a floor panel. The second leg 320 may also include slotted holes 324 that receive fasteners, such as screws, to attach the floor bracket 300 to a floor panel. The slotted holes 324 allow the floor bracket 300 to be loosely attached to the floor panel while being adjusted along the length of the slotted holes 324. The second leg also includes an opening 326 configured to receive the floor receiver 230. The opening 326 has a corresponding size and shape to the floor receiver 230, but the opening 326 may be slightly larger than the floor receiver 230 to allow the wall bracket 200 to be adjusted while the floor receiver 230 is inserted in the opening 326 in the floor bracket 300. After the floor receiver 230 is inserted into the opening 326 and the wall panel is set in place, the wall bracket 200 may be locked in place via locking screws 334. The locking screws 334 screw into threaded sleeves 330 attached to the second leg 320 of the floor bracket 300. The threaded sleeves 330 may be attached to the second leg 320 via a spacer 332. The spacer 332 may be welded to the second leg 320 and the threaded sleeve 330. The spacer 332 puts distance between the second leg 320 and the threaded sleeves 330 so that the locking screws 334 can be screwed into the threaded sleeves 330. After the locking screws 334 are screwed into the threaded sleeves 330, set screws 336 may be screwed into threaded holes 338 in the top of the threaded sleeves 330.
FIGS. 2-7 show a floor to wall connector 100 wherein the wall bracket 200 and the floor bracket 300 are connected. The floor receiver 230 of the wall bracket 200 inserts through the opening 326 in the second leg 320 of the floor bracket 300 to connect the wall bracket 200 to the floor bracket 300. Once inserted through the opening 326, the floor receiver 230 may be adjusted horizontally or left and right within the slightly oversized opening 326. The height adjustment screws 242 are screwed through threaded holes 236 in the floor receiver 230 until the end of the height adjustment screws 242 rest on the top of the second leg 320 of the floor bracket 300. The wall bracket 200 may be adjusted vertically by screwing the height adjustment screws 242 in and out of the threaded holes 236 to change the distance between the second leg 320 of the floor bracket 300 and the floor receiver 230 of the wall bracket 200. Once the floor receiver 230 is positioned in the opening 326 so that the wall panel attached to the wall bracket 200 is properly placed, the locking screws 334 lock the wall bracket 200 in its position by screwing through the threaded sleeves 330 until the ends of the locking screws 334 are tight against the floor receiver 230. The locking screws 334 lock the wall bracket 200 in place by clamping the floor receiver 230 against the side of the opening 326 in the second leg 320 of the floor bracket 300. The set screws 336 are then threaded in the holes 338 in the threaded sleeves 330 to further lock the locking screws 334 in place.
The floor to wall connector 100 can be attached to wall panels and floor panels prior to lifting and placing the wall panel. The floor to wall connector 100 also provides a holding point for lifting the wall panel with a crane thereby eliminating the need for an additional lifting mechanism. The connector 100 also includes features which provide options for adjusting the floor bracket 300 in and out and adjusting the wall bracket 200 left and right and up and down relative to the building. These options for adjustment account for site tolerances. The connector 100 also has a slim profile which reduces the effort required to cover the connector 100. The connector also provides fire protection, withstands seismic events, and uses a minimum number of mechanical fasteners.
FIG. 8 shows a plurality of floor brackets 300 connected to a floor panel 400 and a plurality of wall brackets 200 connected to a wall panel 500. FIG. 8 shows a floor panel 400.
