A prefabricated post assembly is proposed. The prefabricated post assembly includes a vertical post having at least one assembly surface and a horizontal post having an assembly module mounted at an end thereof to be coupled to the assembly surface, in which at least one upper insertion hole is formed at an upper portion of the assembly surface and at least one lower insertion hole is formed at a lower portion of the assembly surface.

A Z-shaped attachment element for use in building construction is disclosed. The Z-shaped attachment element is made from a single piece of sheet metal that is first cut and then bent to form the Z-shaped cross-sectional profile. The Z-shaped attachment element comprises: an elongated upper flange; an elongated lower flange, wherein the upper and lower flanges are spaced apart and substantially parallel to each other; an elongated middle web section between, and connected to, the upper and lower flanges along respective upper and lower lengthwise bends (wherein the middle web section is diagonal in relation to the position of the upper and lower flanges, thereby defining a generally Z-shaped cross-sectional profile); and a plurality of notches formed along the lower lengthwise bend and into the lower flange and the adjoining middle web section, but not into the upper bend or the upper flange, of the Z-shaped sheet metal attachment element.

In a joint structure of steel beam structure, a bracket is coupled and fixed to the lateral side of a large beam or a pillar and a steel beam is coupled to the bracket such that the steel beam is coupled to the lateral side of the large beam or the pillar. One end of the bracket is coupled to the lateral side of the large beam or the pillar, and the other end is inclined such that the lower part thereof forms an acute angle, wherein a first attachment plate is coupled to the inclined end part of the bracket such that a fixed length thereof protrudes from the upper end of the bracket. The lower part of one end of the steel beam is inclined at an obtuse angle so as to correspond to the other inclined end of the bracket.

A collar flange assembly welding fixture is disclosed, including a stand, a circular mount structure, and a support assembly which are configured to provide access to a front side and a back side of a collar flange assembly held by the support assembly. The stand has a plurality of circumferential bearings equidistant from an axis of rotation, the circular mount structure is rotatably supported by the circumferential bearings, and the support assembly is configured for mounting on the circular mount structure.

An internal splice joint that facilitates coupling of a pair of joist members together is provided. The internal splice joint includes a main wall, first and second side flanges, and first and second end flanges. The first side flange extends upwardly from the main wall. The second side flange extends upwardly from the main wall and is spaced from the second side flange. The first end flange extends from the first side flange. The second end flange extends from the second side flange. The first end flange and the second end flange extend inwardly towards each other and are spaced from each another. A joist assembly that includes the internal splice joint is also provided.

A slide clip includes a first plate and a second plate coupled at a juncture. The first plate and the second plate form an angle at the juncture. The second plate has a first elongated slot, a second elongated slot, and a third elongated slot, each extending parallel with the juncture. The first elongated slot and the second elongated slot are each offset from the juncture a first distance. The third elongated slot is offset from the juncture a second distance that is greater than the first distance.

A Z-shaped attachment element for use in building construction is disclosed. The Z-shaped attachment element is made from a single piece of sheet metal that is first cut and then bent to form the Z-shaped cross-sectional profile. The Z-shaped attachment element comprises: an elongated upper flange; an elongated lower flange, wherein the upper and lower flanges are spaced apart and substantially parallel to each other; an elongated middle web section between, and connected to, the upper and lower flanges along respective upper and lower lengthwise bends (wherein the middle web section is diagonal in relation to the position of the upper and lower flanges, thereby defining a generally Z-shaped cross-sectional profile); and a plurality of notches formed along the lower lengthwise bend and into the lower flange and the adjoining middle web section, but not into the upper bend or the upper flange, of the Z-shaped sheet metal attachment element.

A light steel framing plenum includes a horizontal plenum member, a vertical plenum member and plurality of screws. The horizontal plenum member includes a pair of horizontal plenum flanges and horizontal plenum web. The horizontal plenum flanges have dimpled screw holes formed therein. The vertical plenum member is attached to the horizontal plenum member. The vertical plenum member has a pair of vertical plenum flanges and a vertical plenum web therebetween. Each vertical plenum flange has a step formed therein for receiving the horizontal flange from the attached horizontal plenum member. A plurality of screws are provided to attach the horizontal plenum member to the vertical plenum member. The lights steel framing plenum provides a generally flat surface for attachment thereto.

The present disclosure is directed to multi-functional isolation pads that can be used in combination with both clamp-on cable trays and guide-on cable trays without any user manipulation (e.g., folding) of the isolation pad.

The disclosed technology provides a seismic yielding connector. The seismic yielding connector includes a U-shaped plate configured to connect a side stud of a panel to another component of a panel and a yielding plate located between the U-shaped plate and the side stud of the panel. A high-strength bolt connects the U-shaped plate, the yielding plate, and the side stud of the panel to a structural column. A bushing is located between the U-shaped plate and the structural column.
