Assembly system for modular building units
An assembly system for modular building units having a floor and a plurality of walls is provided. The assembly system includes a floor platform, a plurality of wall platforms, and a plurality of hinge assemblies. Each of the plurality of hinge assemblies may be rotatable to at least a first position and a second position when attached to the floor and the one of the plurality of walls. In the first position, the walls and the floor are generally parallel while in the second position the wall and the floor are generally perpendicular. Methods of use are also provided, in which, during use, the hinge assembly of the system may be rotated from the first position to the second position at least in part by moving the walls in an upwards direction relative to the floor.
1. An assembly system for modular building units having a floor and a plurality of walls, said assembly system comprising:
a floor platform, capable of supporting the floor and distinct from the floor;
a plurality of wall platforms, each capable of supporting one of the plurality of walls, and located distal to the floor platform; and
a plurality of hinge assemblies, each having a first end and a second end, each of said ends rotatable around a hinge spaced apart from and external to said floor and said plurality of walls, said first end having a floor plate, said second end having a wall plate, said floor plate being releasably attached to the floor platform, and said wall plate being releasably attached to one of the plurality of walls, said hinge assemblies rotatable about said hinge to at least a first position and a second position when attached to said floor platform and said one of the plurality of walls,
wherein, in said first position, the wall and the floor are generally parallel, and in said second position, the wall and the floor are generally perpendicular;
wherein, in use, the hinge assemblies can be rotated about said hinge from the first position to the second position by moving the walls in an upwards direction relative to the floor, such that when the wall is rotated onto the floor, the wall rests on the floor.
2. The assembly system of claim 1 further comprising a plurality of floor leveling apparatus capable of raising and lowering the floor platform relative to a surface on which the floor platform is situated.
3. The assembly system of claim 1 further comprising a plurality of pistons each driving a rod capable of displacing the floor relative to the floor platform when the floor is positioned on the floor platform.
4. The assembly system of claim 3 wherein the floor platform comprises a plurality of leveling tables having top surfaces.
5. The assembly system of claim 4 wherein said plurality of leveling tables contain a plurality of said pistons and said rods, and said rods extend through apertures in said top surfaces.
6. The assembly system of claim 1 further comprising wheels on said wall platforms.
7. The assembly system of claim 1 further comprising a plurality of hinge assemblies for each of said plurality of walls.
8. The assembly system of claim 1 wherein said hinge assemblies can be removed from the walls and the floor after assembly without affecting the integrity of the pre-fabricated modular building unit, and are reusable.
