Abstract

Claims (30)

1 . A modular building system comprising:

a plurality of rods comprising a corner rod and an edge rod, the corner rod comprising a prong, the plurality of rods configured to connect to each other to form a frame; and

a panel that attaches to the frame to form a side, the panel comprising corrugated metal with folded portions, with insulation disposed into one or more empty spaces between the folded portions,

wherein the insulation comprising a first layer of thermal insulation material disposed within the folded portions and a second layer of sound insulation material layered on top of the first layer.

2 . The modular building system of claim 1 , wherein the panel is attached to the frame by a pair of u-shaped channel pieces positioned parallel to one another with open portions facing one another.

3 . The modular building system of claim 2 , wherein the open portions of the u-shaped channel pieces are configured to secure movement of the panel.

4 . The modular building system of claim 1 , wherein the frame forms a first box frame comprising twelve edges; and

wherein the twelve edges of the first box frame enclose six separate sides.

5 . The modular building system of claim 4 , further comprising a second box frame comprising twelve edges and six sides;

wherein at least one edge of the second box frame is configured to be connected to the first box frame.

6 . The Modular building system of claim 5 , wherein additional box frames are connected to the first box frame and the second box frame to form a habitable structure, the habitable structure comprising:

one or more floors;

one or more windows;

one or more walls; and

one or more ceilings.

7 . A method for constructing a modular building, the method comprising:

connecting a plurality of rods to form a frame, the plurality of rods comprising a corner rod and an edge rod, the corner rod comprising a prong; and

attaching a panel to the frame to form a side, the panel comprising corrugated metal with folded portions, with insulation disposed into one or more empty spaces between the folded portions,

wherein the insulation comprising a first layer of thermal insulation material disposed within the folded portions and a second layer of sound insulation material layered on top of the first layer.

8 . The method of claim 7 , wherein the panel is attached to the frame by a pair of u-shaped channel pieces positioned parallel to one another with open portions facing one another.

9 . The method of claim 8 , wherein the open portions of the u-shaped channel pieces are configured to secure movement of the panel.

10 . The method of claim 7 , further comprising: forming the frame into a first box frame; and

connecting a second box frame to the first box frame.

11 . The method of claim 10 , further comprising connecting additional box frames onto the first box frame and the second box frame to form a habitable structure, the habitable structure comprising:

one or more floors;

one or more windows;

one or more walls; and

one or more ceilings.

12 . The method of claim 8 , wherein the insulation is sprayed onto the corrugated metal before the panel is inserted within the pair of u-shaped channel pieces.

13 . The modular building system of claim 1 , wherein the insulation is disposed on one side or a portion of one or both sides of the corrugated metal.
