The present disclosure provides a structural member (10), such as a beam, a stud or a joist, presenting a predetermined bending direction (B). The structural member comprises a plurality of glued-together wood lamellae (20a, 20b), each having a lamella cross section which is parallel with a cross section of the structural member (10) and a longitudinal direction which is parallel with a longitudinal direction of the structural member and with a principal grain direction of the wood lamellae (20a, 20b). In the structural member, the lamellae (20a, 20b) are formed as radial sections of a log and present cross sections which are triangular or trapezoidal and present a respective base surface (bs1) that is formed at a radially outer part of the log. The lamellae (20a, 20b) are arranged as at least one layer in which base surfaces (bs1) of a pair of immediately adjacent lamellae (20a, 20b) face opposite directions. The base surfaces (bs1) are perpendicular to the bending direction (B).

A shaft member having an engaging part at a lower part is formed to project from a front edge part of a plate-like fitting main body having a required thickness, and an engaging member having an engaging part at a lower part is mounted to a tip surface of the shaft member, the engaging parts communicating with each other, wherein the fitting main body has a gripping part formed of a through-hole at a central part and pin insertion parts which are formed collinearly in the vicinity of an upper edge part and a lower edge part at a rear side of the fitting main body, and wherein a shaft-member insertion part resisting shear stress is provided at a portion different from the pin insertion parts formed on the upper edge part and the lower edge part.

A fire-resistant construction panel (10) includes a structural panel (12) as the web component of an I-joist (24) having an exposed surface (14) and a magnesium oxide board (18) covering the exposed surface (14). Alternately, the fire-resistant construction panel (10′) includes a load-resistant magnesium oxide board (30) being a structural element as the web of an I-joist (24′).

A portal frame comprising at least one header, at least a first column, at least one frame connector for rigidly connecting the at least first column to the at least one header, at least one header fastener configured to fasten the frame connector to the at least one header and at least one column fastener configured to fasten the frame connector to the at least first column. The at least first column is formed of wood or a wood-based/wood-derived material. The at least one frame connector comprises a lateral header connecting portion extending beyond a lateral edge of the first column in a direction towards the center of the at least one header and a column connecting portion extending along at least a portion of the height of the at least first column. The lateral header connecting portion comprises at least one of the at least one header fastening means.

Provided is a multi-layered reinforced wood material which is excellent in fire resistance, has extremely small damages on a support wood material part, and is also excellent in strength. The present invention is directed to a multi-layered reinforced wood material A for use as a building material, the multi-layered reinforced wood material A including a support wood material part 1 for supporting load, a sheet part 3 attached to the periphery of the support wood material part 1, an inflammable wood material part 2 attached outside the sheet part 3 so as not to expose the sheet part 3, wherein the inflammable wood material part 1 is made of a wood material containing therein an inflammable agent, and the sheet part 3 is made of a fiber reinforced plastic.

The innovation relates to a pool covering system that is usable as a flooring surface. The pool covering system includes brackets and support beams spanning the pool opening. The beams provide structural support to cross members and flooring placed on top of the beams. The pool covering system does not require significant drainage of the pool and does not damage the pool structure during installation and use.

An LVL structure is a rectangular cell suitable for weight bearing uses such as floor trusses. The LVL structure includes one or more LVL beams having first surfaces that are a single outer layer of a veneer stack. Fastening plates/devices having penetrating members are used to attach the one or more LVL beams to the LVL structure with the penetrating members penetrating the single veneer layer first surface of the LVL beams substantially perpendicular to the first surfaces. In this way, the penetrating members do not split/separate the layers of veneer making up the LVL beams and tend to secure the penetrated layers of the veneer making up the one or more LVL beams together in a nail like fashion.

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.
