A flooring installation includes at least two floor supports separated from one another by a span distance, the floor supports each having lateral, vertical side walls between which an opening is defined. A bay is defined between the floor supports. A primary subfloor is supported atop and attached to one of the at least two floor supports, the primary subfloor including an overhanging portion overhanging a portion of the bay. A spanning brace is disposed between the at least two floor supports in the bay, the spanning brace engaging on opposing ends the lateral, vertical side walls of the floor supports, one end of the spanning brace extending beneath and spaced from the overhanging portion of the primary subfloor. A recessed subfloor panel is supported atop the spanning brace, the recessed subfloor panel being supported at a lower elevation than the overhanging portion of the adjacent, primary subfloor.

A lean-to rigging apparatus is described for installation in a shaft, such as an elevator shaft, having a wall and including at least one sill opposite the wall. The rigging apparatus includes a spanning beam, a sill support structure, a wall support member, and a hoist connector. The sill support structure on a first end of the spanning beam is designed to seat against a sill in the in the shaft while the wall support member on a second end of the spanning beam abuts against the opposite shaft wall. The sill support structure is rigidly connected to the spanning beam in a hingeless configuration and can seat against a sill in a plurality of seating positions. These seating positions allow the rigging apparatus to be positioned in a plurality of angles and therefore to be installed in shafts of different dimensions. The hoist connector is configured to allow a connection to a hoist device for hoisting various materials from one level to another within the shaft.

A truss bracing system for roof trusses is disclosed. The truss bracing system comprises of a lateral brace and a diagonal brace connected through a pivot point. Both the lateral brace and diagonal brace include a first support member and a second support member where the first support member is angled relative to, and preferably perpendicular to, the second support member. The pivot point allows the diagonal brace to rotate relative to the lateral brace. That is, the truss bracing system has a closed configuration with the diagonal brace resting adjacent and parallel to the lateral brace and an extended configuration with the diagonal brace rotated relative to the lateral brace, such that the diagonal brace is angled relative to the lateral brace. Thus, the truss bracing system provides both lateral and diagonal support to the trusses to which it is attached.

A connection between a stud and one or more separate backing members is made with separate fasteners and a backing connector. The backing connector has a planar web with first and lateral side plates extending therefrom, with the backing members attached to the first and second side plates and the web of the backing connector attached to the stud.

A strut linkage for a steel construction may involve a tower of a wind turbine and/or a corner post of a lattice tower. In order that high forces can be removed via the strut linkage without causing increased stress concentrations, excessive use of material, and/or an excessive structural outlay, a plate element is provided for arranging between, preferably load-bearing, steel construction components. At least one connection element, which may be connected to the plate element, may be utilized to fasten at least one strut and/or guy of the steel construction to the steel construction components via the plate element.”

The present invention relates to using interlocking spacer braces between support members to construct wood and metal framed walls, floors and building trusses. Spacer braces have indentations, extensions, with hook fingers, hook tongues and hook receivers along with U & W shaped clips that interlock horizontally, vertically or diagonally between support members. The spacer braces can form diagonal and lateral wall bracing, diagonal and vertical chords within building truss with either horizontally or vertical orientations, headers above doors and windows and shear walls. The spacer braces can be installed individually or in tandem between wood or metal framing.

The buckling-restrained brace that is capable of being fixed to connected portions of a structure using bolts, the brace includes: a plate member extending in an axial direction, and in which bolt holes for fixing the bolts are formed at end portions of the plate member in the axial direction; and a buckling-restrained member configured to restrain a center portion of the plate member in the axial direction to prevent the plate member from buckling, wherein the buckling-restrained member includes a pipe member surrounding the plate member from the outside in a radial direction, and a filler filling the gap between the pipe member and the plate member, and the plate member includes a fixing plate, a portion of which is embedded in the filler, and the remaining portion is protruded from the filler in the axial direction, and in which the bolt hole is formed at an end portion of the remaining portion in the axial direction.

A support for mounting an electrical box relative to a stud can include a support arm and an attachment feature, with the attachment feature configured to secure the support arm to the stud, and the support arm configured to support the electrical box. The attachment feature can include an attachment section that has a first configuration and a second configuration. In the first configuration, the attachment section can support the support arm at a first depth relative to the stud. In the second configuration, the attachment section can be configured to be folded over itself to support the support arm at a second, smaller, depth relative to the stud.

A hollow tubular joist structure, a joist assembly including a plurality of aligned repetitive tubular joist structures, and a method of constructing this joist assembly. The tubular joist structure may include any suitable cross-sectional geometry. The joist structure includes a tubular top chord; a tubular bottom chord; and, a plurality of diagonals extending between the tubular top chord and the tubular bottom chord. The diagonals may also be tubular. The diagonals are arranged in a zig-zag formation between the tubular top chord and the tubular bottom chord. The tubular top chord may be capable of receiving a power actuated fastener (PAF). The tubular top chord or the tubular bottom chord may also be capable of receiving a utility conduit. A method of constructing a joist assembly of the present disclosure includes assembling a plurality of joist structures each including a top chord, a bottom chord, and a plurality of diagonals extending between the top chord and bottom chord; and, wherein a plurality of the joist structures include a tubular top chord and a tubular bottom chord.

A shear transfer system is provided. In the system a shear tie strap is attached to a first framing member, a second framing member, a third framing member, a fourth framing member, and a fifth framing member of a frame in a framed building. The second, third, fourth, and fifth framing members are orthogonal or oblique to the first framing member. More than one shear tie strap may be present in the framed building.
