5 Sheets-Sheet 5 STRUCTURAL CONNECTIONS FOR BUILDING CONSTRUCTIONS BACKGROUND OF THE INVENTION The present invention relates to structural connections for the construction of buildings, which connections provide interlocking sandwich wall and roof sections, and more particularly, to interlocking sandwich wall and roof sections which are both structural in nature and develop a great strength with less material than is normally used with ordinary constructional techniques. The interlocking sandwich wall and roof sections are self-insulating, are finished both on the interior and exterior sides, are weatherproof and airtight, are simple to put together, and all the pieces thereof come pre-cut to accurate size. All the pieces of the structural connections are also self-leveling and self-plumbed.

It is known to construct, for instance, A-frame structures by using a ladder method for constructing the walls and beams, which method employs two-by-fours and two-by-eights connected together by using a given angle. However, this method is only suitable for A- frame structures.

It is also known that a tightenable cable can be employed for holding together a temporary or movable building. With such a conventional method, the side walls of the temporary building are joined together as the roof boards by an angular rabbet method to allow for slippage when tightened. This type of joint, however, requires a metal piece to hold the comers together and provide water-tightness.

It is also known to provide a metal frame which is designed to hold up a building and at the same time allow for wirin'g, plumbing, gas, etc. However, such an arrangement usually requires wiring and plumbing prior to the completion of the building. In some conventional structures, the wiring of the building requires pre-molding of the wiring into the wall sections, thus requiring pre-planning of electrical requirements prior to the construction. Therefore, the occupant finds it ex- [tremely difficult at a later date to add on electrical wiring for varying requirements.

SUMMARY OF THE INVENTION It is the aim of the present invention to overcome the problems and disadvantages of the prior art constructions and to provide structural connections which greatly increase the speed and-ease with which a building is put together.

The underlying problems are solved in accordance with the present invention by providing interlocking sandwich wall and roof sections, channel baseboards which permit wiring after complete construction of the building, and an interlocking laminated beam and post assembly.

The interlocking laminated beam and post assembly can be made from two-by-four inch material with a plywood gusset center or tongue that is offset so as to allow the joining of two or more beams or posts, thereby increasing the size as well as the strength of the beam or post. This assembly provides the advantage that the beams can be assembled in any length and eliminates the need for separate left-hand and righthand structures since by reversing one structure it will interlock with any other structure. In addition, the joist,

vertical post and beam interlock to form a structural unit.

An advantage of the interlocking sandwich wall and roof sections is that it is structural in nature and develops great strength with less material than is normally used with ordinary constructural techniques. The walls and roof are self-insulating, and are finished both on the interior and exterior sides. Further, the sections are weatherproof and air-tight, are simple to put together and are self-leveling and self-plumbed. In addition, the sections are extremely simple to put together since all that is needed is a simple tool such as, for example, a power screwdriver.

It is an object of the present invention to provide an assembly which is self-leveling, self-squaring and which obviates any need for cutting material on the job site.

It is a further object of the present invention to pro- I vide a sandwich wall construction with a totally dry insulation, thus providing a constant K factor. In this connection, such an arrangement provides an interior and exterior moisture barrier.

It is also a further object of the present invention to provide the walls with a vinyl covering to eliminate the need for any painting thereof.

It is a still further object of the present invention to insulate the floors as well as the walls and ceilings. Even the interior walls would be insulated because of the material used, thereby eliminating noise and allowing the desired temperature differential between rooms.

It is a further object of the present invention to make practical the use of electrical heat because of the tightness of compression strips used in constructing the building.

It is still a further object of the present invention to provide a structural connection method which yields a maximum amount of strength with a minimum expenditure of materials, thus providing a great savings.

It is still a further object of the present invention to provide a roof that is totally dry before roofing material is put thereon because of the compression fittings in the roof.

It is still another object of the present invention to provide further maximum strength with minimum cost because of the ability to add one joist or beam section to another in joist assembly.

It is still a further object of the present invention to provide that the plumbing, heating, wiring, etc., can be added after the structure is complete, so that the wiring, for example, can be modified as requirements vary.

As shown in FIG. 2, roof sections 7 are placed along the beams 1 and are joined thereto as will be described hereinafter in greater detail.

As seen in FIG. 3, roof section 7 is joined with the beam 1. The beam 1 actually consists of two portions 1A, 18, as shown in FIG. 9, and an offset portion or tongue 8 which can be made from plywood or any other suitable material. Vertical post 4 also consists of two portions 4A, 43, as shown in FIG. 7, and an ofiset portion or tongue 9 which also can be made of plywood or any other suitable material. The vertical post 4 is connected with the beam 1 and floor joist 2 by any suitable means, such as, for example,

carriage bolts

10, 11. An outside wall section 12 is provided and rests upon flooring 13. The gusset or tie piece 3 is connected with the beams 1 by means of, for example, carriage bolts 14 and the beams themselves are joined at the peak by means of, for example, carriage bolts 15. The roof sections 7 are joined together at the peaks by means of ridge mouldings 16, which can be bi-partite or a unitary part joined to the roof sections by conventional means such as screws. The roof section nearest to the ground is provided with an end strip 17. In addition, roofing material 18 can be applied over the exterior surface of the roof sections for additional sealing as well as aesthetic reasons. At the termination of the roof sections, flashing 19 is provided along the beams 1. A spacer or

spacers

20, 21, 22 are provided on the interior of a roof section 7. The outer wall section 12 is provided with a space 23 for connection with the roof section spacers by conventionaimeans such as a wood screw. Compression strips 24, 25 are provided in the rails at the joint portion of the outer wall section 12 and the flooring 13 so as to provide the necessary sealing requirements.

Referring now to FIG. 4, it is seen that the flashing 26 from the flooring continues along the floor joist 2 so as to abut against the beam 1. A caulking strip 27 is provided between the flashing 26 and the tongue 8 for sealing purposes. The ceiling joist 5 actually consists of two portions 5A, 58, as seen in FIG. 6, and an offset portion or tongue 28. To form a second floor, flooring 29 is placed on the ceiling joist 5 and is connected thereto by conventional means. FIG. 5 likewise shows the connection of the vertical post 6 to the ceiling joist 5 and the flooring 29.

In FIG. 6, it is seen how easily joist sections can be assembled so as to increase their length as well as their rigidity. Splines 30, which can be made from plywood or any suitable material, are placed at desired intervals along the joists or the beam. The spline 30 is provided with a bore 31 therethrough. A second joist 5 has a corresponding pocket 33 for spline 30 and bores 34 in joist portions 5A, 5B which align themselves with bore 31 for the reception of, for example, a carriage bolt 35 so as to be rigidly connected.

FIG. 7 shows a comer detail of the structure having

outer wall sections

12 and 36. The end rails 37, 38 of

wall sections

12, 36, respectively, are joined together, for example, by a wood screw 39. The other end of the wall section 36 is joined at an intermediate

vertical post

44, 45, by end rail 40,

spacers

41, 43 and a wood screw. The end of the spacer 43 which abuts against the tongue of the intermediate vertical post is provided with a channel or space for accommodating wiring or the like. On the other side of the intermediate vertical post, another wall section 46 can be provided. This section can be connected by mating engagement with the tongue of the vertical post as well as

fillets

47, 48 joined to the

post portions

44, 45 by conventional means such as

screws

49, 50.

Any exterior wall panel can be cut to accommodate a window or a door. Rigid vinyl windows 51 fit in the cutout with an exact fit using an exterior molding 52 and an interior molding to seal and hold the window tightly to the wall as shown in FIG. 7b. In addition, FIG. 7a shows a modified fonn of the comer assembly and exterior wall joint connection, wherein parts similar to those in FIG. 7 are designated by the same but primed numerals.

FIG. 8 shows the connection between an inside wall section 52 between the ceiling joist 5 and the flooring 13. The wall section 52 is of sandwich construction consisting of

plywood sheets

53, 54 covering a synthetic resin, such as Styrofoam, intermediate sheet 55. The wall section 52 is accommodated within a baseboard retainer 56 and a removable baseboard cap 57. The baseboard retainer 56 is joined to the flooring 13 by means of, for example, a wood screw 61. The flooring 13 likewise consists of a sandwich construction including

plywood cover sheets

58, 59, which sandwich a Styrofoam sheet 60. The removable baseboard cap 57 is joined to the baseboard retainer 56 by conventional wood screws 61. The Styrofoam sheet 55, the baseboard retainer 56 and the-retainer cap 57 define a channel 89 for accommodating wiring or the like. The other end of the wall section 52 is joined to the ceiling joist 5 by providing that the

plywood cover sheets

53, 54 straddle the tongue 28and the spacer 28A. In addition, conventional means can be employed for further joining the wall section 52 to the ceiling joist.

FIGS. 11, 12 and 13 show further details for accommodating electrical wiring within the structure. For example, the outer wall section 12 is provided with a channel member of .plastic or other suitable material which is arranged between an uppermolding member 62 and a lower molding member 63. The channel member.64 is of substantially U-shaped configuration and is provided with lips at the ends of the legs for retaining a removable cap 65. Where an interior wall section 52 abuts against an outer wall section 12, space 89 and the channel member 64 communicate with each other so as to accommodate any wiring. It can be readily seen that this arrangement allows wiring to be added at a later time depending upon the needs of the occupant. FIG. 13 shows that the outer sheet of the wall section 52 can be provided withan electric outlet hole 66 cut therein to accommodate an electrical switch or outlet box 67. A deeper box would have a surface extension ring around it to compensate for'the thickness of the wall. The channel 68 communicates with the space 58 and can be fon'ned by lowering a small soldering iron through the Styrofoam sheet, thereby forming a hardened wire space asthe soldering iron drops into the baseboard space 89. On an outside wall, e. g., wall section 12, hole 68 can connect through the

back side construction

78, 79 or of unitary construction. As seen of channel member 64 which canbe provided with knock-out portions to receive electrical connectors. This would be used, of course, to connect any outlets or switches on outside walls.

FIG. 9 shows the interlocking sandwich connection of the roof section at the beam 1. One end of theroof section is provided with a spacer 69, while the other end is provided with a spline tongue 70 having a groove at the outer end thereof to accommodate a compression strip 71 of, for example, soft plastic material. This tongue and groove arrangement of the roof sections provides the necessary scaling for the structure. As seen in FIG. 9, the roof sections are of sandwich construction wherein outer and

inner cover sheets

72, 73 sandwich a Styrofoam sheet 74 therebetween. The roof sections are joined to beam portions 1A, 18 by means of, for example, screws 75, 76. I

FIG. 10 shows the general arrangement of the door and jamb moulding. The wall section 36 is provided with jamb moulding 77 which can be of either bi-partite in FIG. 10, the two

members

78, 79 of the jamb moulding are joined to the wall section by means of screws 80,- 81. The door section 82 is the cut-out piece replaced back into the opening after adding strip 86 at the end thereof in face-to-face relationship with the jamb moulding. The door section can also be of sandwich construction consisting of

outer sheets

83, 84

which are made of plywood or any other suitable terior of the structure can also be quickly accomplished without the need foremploying complicated constructional techniques or great amounts of material.

As shown in FIGS. 14 to 16, the present invention can be used to erect any type of structure by taking appropriate measures. The beam 1 can be cut at a desired-roof overhang point, thereby eliminating the triangular base section. The vertical post 4' is then extended to standard ceiling height but remains the same in terms of connection with the exception of a gusset 87, shown in FIG. 16, which can be an I. or T gusset and which fits into a large pocket at the intersection of the rafter beam 5' and vertical post 4. With the same structural variations, long distances can be spanned between the outside walls.

While I have shown and described embodiments in accordance with the present invention, it is to be clearly understood that the same is susceptible of numerous changes and modifications as will be apparent to one of ordinary skill in the art.
