Abstract:
A joint between a wood load bearing element of a building and another load bearing element or a foundation includes longitudinally extending elements across the joint and fixed to the load bearing elements at or towards either end of each longitudinally extending element, with at least two such longitudinally extending elements on each of two opposite sides of the joint, at locations spaced across a longitudinal axis through the joint, the longitudinally extending elements holding the joint together.
Abstract:
An elongate framing member (2, 6) with a U or C shaped cross-section has a pair of mutually parallel side walls (12, 14) which extend in a common direction from opposite edges of a base wall (13, 15). At least one of the walls has a through hole (20, 21) that can be surrounded by a dimple that is offset out of the general plane of the respective wall. Such framing members can be joined together to form a frame, e.g. a triangular roof truss, by fitting a fastener through the through-holes of respective framing members. The dimples facilitate pre-alignment of the through holes prior to fitting the fastener, by nesting the dimples of respective framing members inside one another. The fastener may, for example, be a self-tapping screw, a rivet, or a threaded bolt (24) and nut (26), the bolt shank passing through a spacer sleeve (22) and through pairs of transversely aligned through-holes (20, 21) in the side walls (12, 14) of each chord (2, 6).
Abstract:
Un système de construction qui réalise une préfabrication poussée de la structure de bâtiments du type poteaux et poutres, préfabrication qui permet une industrialisation de ce type de construction. Le principal aménagement qui permet de réaliser cet objectif dans les mêmes conditions techniques, voire meilleures que dans le système classique, est le recours massif aux contreventements aussi bien dans le sens vertical que dans le sens horizontal. Un tel système de construction présente un intérêt spécial pour les régions à risque sismique est élevé, car le bâtiment est très léger, constitué d'un ensemble d'unités autosuffisantes structurellement, fortement triangulées et donc très peu déformables, tout ceci à un coût relativement réduit.
Abstract:
A modular construction system includes an elongate construction element (1) comprising an elongate body (2) including a longitudinal web (3). The web defines opposite first and second edges (4,5) and a longitudinal centreline (6). The first and second edges are spaced from the longitudinal centreline by a pre-determined distance. A longitudinal first flange (7) of uniform width extends transverse to the web along the first edge in a first plane, and defines a flange edge (9) at a pre-set separation from the web. The elongate body defines opposite first (10) and second ends, and the elongate body has, at the first end, a first end plate (11) orthogonal to the longitudinal centreline. The first end plate defines a first aperture (12) at a selected distance from the first plane. The first aperture is provided in the plane of the web.

The web defines at least one second aperture at the same selected distance from the first plane. The first flange terminates at a flange end short of the first end by a distance at least equal to the pre-set separation, whereby the first end of the elongate construction element may be coupled to the web of a second such elongate construction element with the first end plate of the first elongate construction element in facial contact with the web of the second such elongate construction element by a bolt and nut combination, the bolt having a shaft arranged to extend through both the first aperture of the first elongate construction element and a second aperture of the second elongate construction element.

A truss for use in a staggered truss system in provided. The truss includes at least one slip joint for allowing relative movement between the top chord of the truss and the bottom chord of the truss. The staggered truss system may be suitable for use in seismic regions.
Abstract:
The end of a transversely extending beam is joined to a wall structure by a self-releasing structural assembly. It has a first portion anchored to the wall. A second, fireproof and non-thermally degradable portion of the assembly sticks out from the wall. The assembly has a thermally degradable member mated to the second portion of the structural assembly. Both portions have slots for accepting beam fasteners. The beam fasteners squeeze the end of the beam, the support bracket seat, and the consumable, thermally degradable member in compression. When exposed to heat or flame the consumable, thermally degradable member softens, releasing the tension in the beam end fasteners, and releasing the compression in the structural sandwich of parts. The end of the beam is then able to translate away from the wall structure. The consumable member can be inspected without removing the beam end from the seat.
