Abstract: Structural joint members for a space frame system with a node joint having threaded apertures, structural strut members with threaded end sections, and a connecting member. The connecting member includes an elongatged threaded bolt, a fixed nut locked on one bolt end with a set screw, and a jam nut threadably engaging the other bolt end. The bolt threadably engages the node joint and the strut threaded end section with the fixed nut secured against the node joint and the jam nut secured against the strut end section to lock the structural joint members together. A snap-on cap covers the connecting member.

Abstract: This disclosure relates to a floor construction comprising a concrete slab which is supported adjacent its edges of the slab. A plurality of cellular raceways are embedded in the slab, and at least one intermittently bottomless trench runs across the raceways. The trench is located along a line where the bending moment on the slab is substantially zero. The construction further comprises a plurality of post-tensioned tendons which extend across the slab, underneath the trench and between the raceways.

Abstract: A preset block assembly adapted for use with an underfloor electrical distribution system having one or more electrical conductors enclosed in elongated, laterally spaced cells. The block assembly includes a housing having a terminal portion that rests on the top wall of one of the cells and encloses an opening therein. In one embodiment, the housing has depending portions at each end thereof which seat in valleys defined by cells on each side of the central cell of a set of three. In another embodiment, the housing has only one depending portion which seats in the valley between a pair of the cells. In both embodiments, an outwardly extending sleeve on the side wall of the depending portion or portions extends into an opening in the side wall of the cell or cells adjacent to the cell underlying the terminal portion.

Abstract: An improved stud wall structure comprising a folded T-shaped windstrip brace member installed in a saw kerf extending diagonally across the structure for substantially eliminate racking. The T-shaped brace member has a double layer top member portion and a pair of spaced apart flanges extending substantially perpendicularly from said top member portion. The flanges are unconnected at their respective outwardly extending edges, and fasteners such as nails driven through the brace member wedge the unconnected flanges against the sides of the saw kerf to hold the brace member in place on the structure.

Abstract: In a building having floors or roof resting on peripheral beams supported by columns and non-load bearing curtain walls enclosing the building, the improvement comprising a plurality of vertical members, constituting part of the curtain wall framing, having at least one flange perpendicular to a horizontal member joined to the building, and a plurality of metal clips joined to the horizontal member and securing the vertical member flange against horizontal movement but permitting unrestrained vertical displacement of the adjoining horizontal member relative to the vertical members which are a part of the curtain wall. In this way, roof and floor deflections do not apply compressive forces to the curtain walls.

Abstract: Disclosed are novel building face panels, liner panels, wall panels and wall structures made from such panels. The wall panel is made from a face panel metal skin and a liner panel metal skin separated by an insulating core, such as of rigid polyurethane foam. The panels have novel male and female edges which facilitate assembling the panels into wall structures. Fasteners extend through the female edges of the wall panels securing the inner and outer metal skins to a supporting means such as girts thereby holding them together against negative pressure and fire.

Abstract: Method and means for adapting a poured concrete floor above a wire distribution system for installing outlets connecting with said system. A composite block assembly comprising a rupturable block covered by a hold-down plate having an access opening is preset at selected locations in the floor before the concrete is poured. To complete an outlet installation, the concrete above the access opening in an assembly is removed and the material of the block is withdrawn through the access opening, leaving a void in the concrete floor in which the components of an outlet assembly can be installed.

Abstract: Cellular floor panel assembly is made by precoating one or more metal sheets with anti-corrosion paint or similar protective covering, then forming a fluted first plate and a flat or fluted second plate and connecting the plates in face-to-face contact with rivet-like fasteners. In a preferred embodiment, the structure is formed of a single sheet folded to form upper and lower sections.
