Abstract: The bracket described herein comprises a device for supporting and holding the sidewall of a conduit trench. These conduit trenches are designed to lie on the ground or may be submerged with the top at ground level. Pipe, conduit, electrical cables, etc. may be laid in the trench with the sidewalls held in place by this new bracket. The bracket comprises two angle irons spaced parallel to each other and fastened to each other by crosspieces at the ends thereof.

A pair of chords are placed on each side of the line of blocks and are moved along with the blocks. The chords and blocks are moved past apparatus which drives fastening elements through the chords and into the blocks to secure the chords and blocks together in a rigid construction. Spacer lock plates may also be used to separate and lock the two chords in position, each spacer lock plate including opposed cuts on opposite edges thereof for receiving the chords, a stem portion between the cuts, and toothed flanges at each side of the stem portion.

Abstract: A sheet metal web unit for interconnecting vertically spaced apart, horizontal wood chords, is formed as an elongated channel-shaped strut with integral, flat, connector plates on its upper and lower ends. The channel is curved and shallower at the lower end of the strut and gradually gets deeper and flatter towards the upper end. The width of the channel gradually decreases and the depth of the channel legs gradually increases from the lower end to the upper end of the strut. A W-shaped web unit is formed of four of such struts integrally connected together by common connector plates. The connector plates overlap vertical face portions of the wood chords and have struck-out teeth for embedding within those overlapped face portions. The ends of the channel leg portions which are closest to the connector plate teeth are extended to overlap and also embed into the adjacent chord face portion to thereby reduce the load on the tooth nearest to the respective strut end.

Abstract: This invention is concerned with a device for eliminating seams at the butt joints caused by the installation of contiguous wall boards in building construction.A bracket, having means for fastening to the studs, has a slightly recessed surface. The butting edges of the wall boards that are fastened to the studs are screwed down tightly on the recessed surface of the bracket. The wall boards, being somewhat flexible, form a concave outer surface slightly below the plane of the wallboard surface that is mounted on the stud. The concave area is taped and then filled with a selected filling material or a joint compound, bringing the new surface formed thereby back to the original plane of the wallboard. The bracket is permanently secured by the wallboard so there will be no movements, and the filling and taping procedure completely conceal the joint lines, so that the wallboard can be painted or wallpapered and will appear as one continuous surface.

Abstract: Modular support systems constructed from a plurality of transportable modular components which are capable of being rapidly assembled and disassembled at an on-site location.

The support systems are comprised of a plurality of rails and metal rungs for extension between and attachment to the rails in a variety of positions to form various structures. The rungs are provided on each of their opposite transverse ends with tabs capable of fitting through complementary slots in the rails. The tabs may be displaced so as to make the ends of the rungs captive in the rails.

Abstract: The invention comprises an improved connector for providing a sloped roof deck between horizontal joists and a plurality of roof trusses. A plurality of sets of integral connectors are used for connecting the roof trusses to the joists with the roof trusses being in a parallel array and perpendicular to the joists. Each of the integral connectors has a base element for mounting to the joist and a support element for mounting to the roof truss with a coupling means disposed therebetween. Each set of connectors has a discrete size coupling means to dispose the support elements at different heights relative to the base elements thereby sloping the roof trusses at the acute angle relative to a horizontal. The sloped roof deck generally comprises a plurality of sheet members disposed between adjacent roof trusses of the parallel array.

Abstract: A floor joist formed of a pair of parallel wood chords, such as 2.times.4's, which are spaced apart and interconnected by sheet metal plates. The plate is normally vertically arranged and its upper and lower edge portions are slit and bent into alternatingly opposed legs having a horizontal wood engaging support portion and a vertical connector portion for overlapping the wood strip vertical faces. The central portion of the sheet forms a pre-sized spacer for fitting between the two wood chords. Thus, each connector plate forms upwardly and downwardly channel-like formations to each receive a chord, with a central spacer portion for maintaining the spacing between the chords. The leg connector portions are formed with struck-out teeth which are embedded into the wood chords for providing the complete joist assembly.

Abstract: A light fixture support is provided comprising a support bar having slots at the extremities which cooperate with inverted "T" members forming the framework for a conventional suspended ceiling to adjustably locate and secure a light fixture within the framework. The slot configuration defined by the light fixture support permits the enlarged extremity of the upstanding portion of the "T" member to be rotated for insertion within the slot, returned to a vertical position, and retained within the slot. If desired, an adjustable support may be provided for accommodating a variety of "T" member spacings or for compact packaging with a light fixture.

Abstract: A new building structural system is described that employs unique elements to interconnect standard structural members in a simple, economical and effective manner. These unique interconnecting elements interconnct a girder and a span member of a building structure, the span member being either a joist or a truss. They consists of two interlocking pieces or elements, one connected to the end of the span member and the other to the side face of the girder member. These unique elements incorporate shaped involutions, webs and reinforcing members that interlock as one element seats down upon the other to interconnect the members in a rugged, rigid fashion. The resulting building structure provides both a flexibility of design and a simplicity of assembly that is remarkable.
