(/4445; 4% arrfz bmw m A TTORNEY TRANSPOR'IABLE PREFABRICATED BUILDING STRUCTURE WITH CANTILEVERED ROOF TRUSSES BACKGROUND OF THE INVENTION greatly hampered by the problems of transporting the finished building to the final location without the costly procedures of handling the buildings without stress and strain. Thus, a great deal of finishing work had to be finallydone on the job location because of the stress and strains to which the building was subjected during moving, resulting in high costs and the defeat of real complete factory production of the building.

SUMMARY OF THE INVENTION One of the objects of this invention is-to provide a structurally sound house of conventional size and appearance at a minimum of cost.

Another object is to provide the combined permanent structure of the building and the structural requirements of transporting the building through itsrnanufactun'ng stages, transportation, and the placement of the building on its permanent support piers as one and the same wherein considerable time and expense is saved.

It is a further object to accomplish the combined structural requirements with a minimum weight, material and expense and to do this in keeping with acceptable architectural design.

FIG. 8 is an enlarged fragmentary sectional view on the line 8-8 of FIG. 7.

DESCRIPTION OF THE PREFERRED EMBODIMENT As an example of one embodiment of this invention, there is shown a building structure comprising two longitudinally extending parallel structural trusses 10 and 11 having their outer ends extending beyond the front end 12 and the rear end 13 of the house proper, these projecting ends providing room for installing conveyor'wheels or other devices for the transportation of the building..The structural trusses 10 and 11 may be bowstring laminated beams or any other type of truss of suitable design to carry the required load.

The structural trusses are provided with upwardly extending studs where required to support the laterally extending roof trusses 15 and are securely fastened to the structural trusses l0 and 11, and are of sufficient size and design to carry the roof load of the roof 16, the front wall 12, the rear wall 13, the sidewalls 17 and 18, and the floor l9. The outer wall sections 12, l3, l7, and 18 are securely fastened to and suspended from the roof trusses l5, placing the outside wall studs 20 in tension. These tension wall studsmay be incorporated with suitable tension rods or other suitable apparatus to insure adequate strength. The floor joists 21 are hung in places between the lower portions of the outer walls and the structural trusses and securely fastened. The floor joists may be hung in three sections as shown in FIG. 6, or may be a continuous joist spanning the total width between the sides 17 and 18 of the building or any combination of the same.

The structural trusses l0 and I1 as shown in FIGS. 5 and 7 as extending beyond the front and rear of the building proper can be used to support porches at the front and rear after the building is transported and placed on its footings or piers, or the truss ends may be cut off as desired. The structural trusses l0 and 11 may be supported on four or more piers 22 located so as to distribute loads and in so doing eliminate the necessity for continuous footings and foundations.

The structural trusses l0 and 11 are provided with a plurality of lifting eyes 23, FIG. 8, or similar devices suitably attached as by nuts 24 on the rods 25 which can run through the roof trusses 15, the wall sections 26, and through the structural trusses l0 and 11. The purpose of this lifting device is to provide the means to lift and move the'building with a crane during manufacturing and to place the building on the piers 22 at the permanent location. This method is of particular advantage in uneven terrain and in areas where movement of the building on its moving dollies in wet and inclement weather is impractical. With this system the complete building can be easily and safely moved without damage from the street to the foundation piers with a crane or other suitable lifting and carrying equipment.

I claim:

l. A prefabricated building structure comprising in combination:

A. a plurality of longitudinally extending horizontal struc tural trusses, said trusses being of sufficient strength to support the structure during transportation, handling and placing on piers;

B. a plurality of laterally extending roof trusses;

' C. vertical studs fixed at their lower ends to the structural trusses and connected at their upper ends to the roof trusses so that the roof trusses are supported on the structural trusses;

D. outside walls for the building suspended from the roof trusses;

E. floor joists hung between theouter walls and the structural trusses; and

F. lifting means extending through roof trusses, said vertical studs and said structural trusses at the junction point of said vertical studs with said roof trusses, and means connected to said lifting means outside of said structural trusses to tightly secure said structure together, some of said liftin'g means being provided with lifting eyes at said junction point for lifting said structure as a unit.

2. A building structure as in claim 1 wherein the ends of the structural trusses extend beyond the outside walls of the buildmg.

3. A building structure as in claim I wherein lifting means compresses a rod extending through the roof trusses at the junction point of the vertical studs with the roof trusses and through said horizontal trusses, and a nut threadably connected to said rod outside of said structural trusses to tightly secure said structure together.

4. A building structure as in claim 1 wherein the outside walls are suspended at their upper edges on the outer portions of the roof trusses and the floor joists are hung from the lower edges of the outside walls and the structural trusses.

Claims (4)

1. A prefabricated building structure comprising in combination: A. a plurality of longitudinally extending horizontal structural trusses, said trusses being of sufficient strength to support the structure during transportation, handling and placing on piers; B. a plurality of laterally extending roof trusses; C. vertical studs fixed at their lower ends to the structural trusses and connected at their upper ends to the roof trusses so that the roof trusses are supported on the structural trusses; D. outside walls for the building suspended from the roof trusses; E. floor joists hung between the outer walls and the structural trusses; and F. lifting means extending through roof trusses, said vertical studs and said structural trusses at the junction point of said vertical studs with said roof trusses, and means connected to said lifting means outside of said structural trusses to tightly secure said structure together, some of said lifting means being provided with lifting eyes at said junction point for lifting said structure as a unit.

2. A building structure as in claim 1 wherein the ends of the structural trusses extend beyond the outside walls of the building.

3. A building structure as in claim 1 wherein lifting means compresses a rod extending through the roof trusses at the junction point of the vertical studs with the roof trusses and through said horizontal trusses, and a nut threadably connected to said rod outside of said structural trusses to tightly secure said structure together.

4. A building structure as in claim 1 wherein the outside walls are suspended at their upper edges on the outer portions of the roof trusses and the floor joists are hung from the lower edges of the outside walls and the structural trusses.
