A glued timber truss (FIGS. 1, 3), comprising chords (1, 2) and therebetween a first diagonal bar (3) and a second diagonal bar (4), which is crosswise relative to the first one, or a web panel (9) connected to each other with an adhesive and a finger joint (FIG. 3), whereby the first diagonal bar is present alongside the second diagonal bar or the web panel.

A thermal break wood and rigid insulation stud is comprised of two non-dimensional lumber sections with a thermal break section of rigid foam insulation therebetween. A non-metallic truss arrangement of mechanical fasteners holds the lumber and insulation sections secured together greatly improving the strength of the thermal break wood and rigid insulation stud. The studs in a wall are 24″ on center. The studs are used for headers and sills and also may be used for top and bottom plates. The corners have an exterior all wood stud, an interior all wood stud and an interior all wood stud adjacent to the interior wood stud completing the interior corner for nailing gypsum board thereto. This corner has a thermal break space between the exterior and interior wood studs for insulation placement. The corners may also have two 3×6 thermal studs oriented 90 degrees from each other and an interior all wood stud for completing the interior corner for nailing gypsum board thereto. This corner arrangement also has a thermal break through its construction.

A glued timber truss (FIGS. 1, 3), comprising chords (1, 2) and therebetween a first diagonal bar (3) and a second diagonal bar (4), which is crosswise relative to the first one, or a web panel (9) connected to each other with an adhesive and a finger joint (FIG. 3), whereby the first diagonal bar is present alongside the second diagonal bar or the web panel.

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 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 semi product for building panels or structural elements comprising several wood lamellas (5) fixed by distance elements (4), a building panel with such a semi product and a method of producing the semi product and the building panel. A method of producing a semi-product for a structural element or for a core for a building panel, wherein the method comprises the step of: attaching at least two distance strips by an adhesive to a first wood board; attaching a second wood board to the distance strips by an adhesive; and cutting the first and the second wood boards and the distance strips in the length direction of the wood boards.

A building framework is disclosed herein having a first structural member, a second structural member, and a third structural member disposed between the first and second structural members, a first web member connecting the first and third structural members in a spaced apart relationship, and a second web member connecting the second and third structural members in a spaced apart relationship. The first web member is positioned relative to the second web member such that the shortest distance between the first web member and second web member is greater than or equal to 5 times the thickness of the third structural member. Additional products, systems, and methods also are disclosed.

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.

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.

An artificial insulated log that has outer and inner wood members that are glued to an inner core of rigid insulation. In addition to the glue, structural connectors are fitted on the top of the logs at specified intervals to provide additional structure support, Each of the wood pieces has a tongue and groove formed to receive other logs. In addition, the insulated core is also fitted with a tongue and groove for alignment. The outer, or exterior, wood member is curved to look like a natural log, The inner wood members are cut flat to for a flat interior wall. Formed corner logs can be used with regular logs to make a finished looking assembly for the building. The corners can be alternated or stacked, as desired.
