7 Claims.

This invention relates to improvements in portable building structures and particularly to building structures made of similar prefabricated structural sections adapted for use in the various parts of the building.

The principal object of the present invention is the provision of strong, light-weight, structur'al units of rectangular form adapted to overlap with their respective faces in a common plane.

Another object of this invention is the provision of a prefabricated structural wall unit adapted to extend from the base member to the header rail and to interlock with the wall units next adjacent thereto.

A further object of this invention is the provision of a rectangular prefabricated wall unit having like spaced apart side panels offset diagonally with notched spacing bars disposed between the outer edges thereof whereby a series of said wall units may be interconnected in planar relation.

Another object is the provision of building structure having tongued corner and wall posts suitable for interconnection with said prefabricated structural sections and with the header rail and the base member.

A still further object is the provision of a structural wall unit provided with spaced apart panels with intersecting strips disposed therebetween to form air cavities.

Other objects are simplicity and economy of construction, ease and speed of erection and dismantling, and adaptability for enlargement or reduction.

With these objects in view, reference will now be had to the drawings, wherein:

In the specification like reference characters refer to similar parts and the numeral 20 is a prefabricated structural or wall member preferably of rectangular form. This member comprises a rectangular frame 22 made of interconnected end bars 24 and side bars 26. One each of said bars 24 and 26 are notched longitudinally at 28 from the inside of said wall member while the other bar 24 and side bar 26 are notched at 28 along the outer corner on the outer face of said wall member, as clearly shown in Figs. 8 to 12 inclusive. An outside panel 38 and an inside panel 32 disposed in parallel relation are rigidly secured to frame 22 in diagonally offset relation as shown, to present like inner and outer wall surfaces. Notch 28 is formed to present a transverse wall 34 and adiagonal wall 36, so that an overhanging tongue 38 is presented.

By referring to Fig. 13 which shows a joint between adjacent structural wall members, it will be noted that when they are moved with their inner and outer faces respectively in common planes, tongues 38 will be interlocked. A suitable screw member 48 is adapted to extend through registering holes 42 and 44 formed'respectively through the inner and outer tongues 38 respectively. The outside tongue 38 is provided with a sleeve nut 45 while inner tongues are provided with countersunk bushings 46 so that when the,

screw 48 is set from inside the building, it will tend to draw the tongues into interlocking relation as clearly shown. Panels 38 and 32 are pref erably made of plywood as shown in detail in Fig. 13. This adds strength to the structure and also presents suitable facings for finishing.

Mounted in frame 22 are transverse strips 48 and longitudinal strips 58. These strips intersect similar to egg crating and meet the inner walls of panels 38 and 32 thereby forming cavities or air spaces 52. The strips 48 and 58 are provided with vent holes I whereby the excess pressure produced during the gluing operation can escape and continually be discharged through port hole 53 formed through end rail 24. After the pressure inside and outside the member has been equalized, the port hole 53 may be plugged to prevent the passage of moisture to the structure. These air spaces serve to insulate the structural member. The parts of this structural member may be securely joined together by any suitable means such as nailing, gluing, etc., so as to present a structure which is light, rigid and durable. It is anticipated that these structural units shall be of suflicient height to extend from the base member to the header, thus eliminating all intermediate horizontal joints in a one story building. Furthermore, this unit 28 is made of a width suitable for receiving the usual door or window apertures. It has been found that a unit 4 foot by 8 foot is suitable for most purposes.

This building is provided with a suitable base 54 comprising side members 56 and end members 58. Each of these side and end members is preferably square in cross-section and is provided at its inner top corner with a W-shaped notch 68, thus providing an upper and outer tongue 62 and an inside bottom tongue 64. The tongues 64 all extend inwardly and are adapted to receive the standard wall members 28 and the slightly modified wall member 2| as floor members with their lower surface in planar relation with the lower plane of base 54. These base parts being in a common plane may be easily positioned on any suitable planar surface to carry the required load. It will be noted that the structural member 2I has its side tongues and end tongues all positioned at the top surface of the member so as to properly engage tongue 64 to carry the load.

The upturned tongues 62 are adapted to receive the end tongues 38 of structural members 28 as hereinafter described.

Corner posts 66 made from a square timber are notched at adjacent corners at 88 and 18 to form an outside tongue I2 and an inside tongue 14. These tongues are so formed and spaced that they will receive the side tongues of interengaging members 28 with the outer walls thereof in planar relation with the outer adjacent surfaces of the corner post. This type of corner post makes it possible to turn a corner with the wall boards without reversing the tongues thereof. When so constructed, the corner posts are alike in construction and may be interchanged; lurthermore, the tongues I2 are provided with holes 15 which register with holes 42 of side wall unit 28 and holes I8 which register with holes 44 formed through the adjacent end wall member 28. These holes I5 and I6 receive the nuts 45 and sleeves 46 respectively to receive the bolts 48 for securing the parts together.

Referring to Fig. '7, it will be noted that the inside corner angle is provided with an angled iron brace I8 having countersunk holes 88 to receive the heads of bolts 48. This angle iron not only strengthens the building but also provides a corner finish. This corner post 66 is offset at its lower extremity to form tongue 82 which is adapted to snugly fit into the upper angled notch formed in base 54 and to engage tongues 62 thereof. It will be noted that the upper extremity of corner post is also offset to present an angled tongue 84 which engages the tongue 86 of the header rail 88. This header rail 88 extends the full length of the building and the upper tongue 38 of the side wall member 28 interengages tongue 86 and is secured thereto by bolts 48 in the same manner as described relative to the side wall members, see Fig. 13.

The wall post 98, best shown in Figs. 7 and 21,

serves to join together adjacent wall members and to serve as anchoring means for partition walls as shown. Post 98 is preferably made of square beams notched at three corners at 92, 94 and 98 to present tongues 98, I88 and I82. The lower end of 98 is transversely notched to form a depending tongue I84 suitable for engaging the tongue 62 of base rail 56 or 58. Also the upper end of 98 is transversely notched to present an upstanding tongue I88 to engage the depending tongue of 8B of the header rail 88.

A cross floor joist I88 detailed in Figs. 25, 26 and 27, having opposed lower tongues H8 and H2 and a top tongue II4 are adapted to receive the tongue of the respective structural members 28 and 2I as indicated in the drawings. End tongues I I6 of joist I88 are adapted to engage the tongue 64 of bottom rails 56 and 58. It is apparent that when the wall post is used for the introduction of a partition that in order to maintain the proper relation of the sectional structural members 28, it is necessary to provide a corresponding band entirely around the building as indicated in the drawings, Figs. 1, 2 and 3.

Referring now to the roof structure, it will be noted that the gable member H8 is rectangular in shape and has a tongue I28 along its bottom edge to interengage with top tongue 38 of end wall member 28 and is secured thereto by means of bolts 48. The inclined edges are also provided with tongues I22 which interengage with roof members as hereinafter described. 'Like gable members are provided at each end of the building and are secured inparallel relation by means of a ridge pole I24 which is'secured thereto by means of bolts 48, as shown in Fig. 18. Like gable members may also be used in the partitions, see Fig. 23.

acaaaae Ridge pole I24 is symmetrical in cross section with notch at I28 to form tongues I23 to receive tongues 38 of roof members I30. as shown in Fig. 15. These parts are secured togetherin theusual manner by bolts 40, as shown.

The roof member I30 is similar to structural members 20 with the exception that the lower end is plain and is provided with a relatively wide frame member I32 to which the outside panel 30 and the inside panel 32 are secured. The space between panels 30 and 32 are divided by strips 40 and 50 to form air spaces 52 for insulation, etc.

The gable members each carry narrow r'oof gable members I34 which function to tie the roof panels to the gable. The roof members I34 are made of an elongated piece of material formed to present a depending tongue I38 adapted to interengage with tongue I22 of the gable member I I8 and is also provided with a tongue member I38 to engage the roof section adjacent thereto. Members I34 also have end tongues I31 to engage tongues I28 of the ridge pole I24.

Abutting roof sections I30 are joined together in like manner as are the wall sections 20 and are secured by means of bolts 40 to permit easy and rapid building and dismantling of the structure. The lower extremity of roof members I30 are secured to the header rail 88 by means of screws I40 as it rests on the upper angled surface 89 of the header rail. 7

The roof sections I30 are joined at the partition to a connector bar I52 having a top side tongue I54, a bottom side tongue I56 and a depending tongue I50, as shown in Fig. 23. Tongues I54 and I55 join with the tongues 38 of adjacent roof members I30 and depending tongue I58 interconnects with the tongue I32 of the partition gable member II8. An end tongue I'I on bar I52 interlocks with the tongue I28 of ridge pole I24.

Referring to Figs. 5 and 6, it will be noted that the angle iron I8 extends upwardly to the roof member and is secured to the header rail 88 by means of screws I42. This angle iron or corner brace member, when so positioned, serves to anchor the roof to the side and end walls of the building.

Each of the building units above described are complete in themselves with bolt holes formed therein to properly register with the respective parts to which they are to be attached. As shown in the drawing, the wall sections are of suflicient s ze to receive door apertures I 44 for the reception of door I46 and also window apertures I48 to receive windows I50. The gable members H0 are made of the same general construction as the wall members and are adapted to receive louvered air vents I52.

With the units described, it is quite apparent that buildings of any desired length, width or height might be constructed without any alterations but by simply interconnecting the wall sections as shown, or in tiers one above the other. When the building is made wider, it is quite evident that the dimensions of the gable member would need to be enlarged in order to obtain the proper pitch angle. The members 20 are shown as used in the vertical position. However, due to their proportionate width and length, may be used horizontally for wall construction. When the building is made wider, the roof members I30 will necessarily be longer to overlap the side walls.

In the construction of the building, the operator usually starts from one end of the building, sets the structural members to substantially complete the building as he progresses toward the other end of the building. This method i found more convenient due to the particular interlock- 3 ing of the various structural units. It is quite apparent that buildings of this character may be I easily and quickly lengthened or shortened.

What I claim as new and desire to cover "by Letters Patent is:
