A connection utilizing a joist hanger to hang a joist or beam from a wood structural support member such as a top plate or header in cooperation with a first plurality of fasteners such as screws or nails and one or more substantially vertical fire-resistant panels such as drywall.

A cellulose-based structural building panel assembly includes a cross-laminated timber (CLT) core which is reinforced with one or more post-tensioned tendons stressed to a pre-selected tensioning force, following the placement as part of the panel assembly. The tendons are provided within a sleeve which is grouted with a channel formed in an underside of the core and which after post-tensioning of tendons is infilled with a binder securing the tendons in a fully bonded configuration.

E.sup.3Lumber is comprised by novel apparatuses as engineered wood systems, methods, apparatuses, tools, adhesives, and manufacturing for construction of structures. E.sup.3Lumber has standardization and optimization surpassing state-of-the-art construction. Each of those systems, methods, apparatuses, material compositions, and material stratifications utilize one-to-many apparatus relations. All formed or machined apparatuses feature innovative features like engineered constraints, multi-tier and hybrid composites, and constrained assembly all situated within novel methods like, the Three E, 4-Tier, Cross Datum Construction, E-Stud, E-Framing, E-Truss, E-Hips, E-Bridging, Continuous Truss methods meet national and international specifications. The Three E's of E.sup.3Lumber are environmental, economic, and engineering and are characteristics found throughout invention intended for the significant improvement of environmental conditions, wood products, and technologies. As a fact, E.sup.3Lumber use decreases deforestation by increasing growth periods of trees by decreasing biomass consumption and all the while providing economic incentive to become greener.

A cross-laminated timber (CLT) and cold formed steel (CFS) connector and system is provided. The CLT and CFS connector comprises a track, at least one fastener, and at least one spring. The track is configured to connect to at least one CFS stud. The at least one fastener includes a head and shaft. The at least one fastener is configured to connect the track to a CLT panel. The at least one spring is configured to receive the shaft of the fastener and compress between the head of the fastener and the track. Methods of installing the CLT and CFS connector and system are also provided.

An arena apparatus for staging a sport is provided. The apparatus includes a floor having a perimeter; and at least one wall coupled to the floor at the perimeter and extending upwardly and outwardly from the floor at an angle relative to an axis perpendicular to the floor, wherein the angle of the wall prevents an athlete from standing on the wall.

A method of constructing a frame of a wood frame building structure is shown and described. The method entails fabricating modules establishing nominally flat structural platforms for expediting assembly of floors, walls, ceilings, and a roof. These modules provide structural frames enabling appropriate finishing materials to be affixed thereto. The finishing materials provide continuous, flat surfaces, with exceptions for penetrations. The method includes assembling the modules such that a longitudinal axis of each model is parallel to those of other modules throughout the frame and perpendicular to a building length axis. Also, each module includes ceiling joists, floor joists, and roof rafters, as appropriate, such joists and roof rafters installed parallel to the building length axis and therefore, perpendicular to the joists and roof rafters. This method minimizes assembly costs of modules and of the framing, while retaining conventional framing performance.

A nut to be used as part of a fastener to be used in multiple ways in various industries or methods has a drive mechanism and stud extending from the drive mechanism with a threaded bore. In addition the nut can be specifically used as a method and as part of special fastener that can be used to join cut, hard-wood members, other naturally occurring manufactured mat members or synthetically man made members, referred to as “timber(s)” or “laminated”, in forming a mat used for heavy construction equipment to run on over ground which is not stable. These mats are commonly referred to as “Crane Mats” or “Laminated Mats” in the construction, mining, pipeline, and oil and gas industries among others.

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.
