Abstract:
The present invention relates generally to a twist drill useful for boring holes into wood, wood composites and other lignin-based materials. In particular, the invention relates in one form to twist drill having a rotational axis and comprising: a body portion having a flute running helically at a helix angle therealong, and a tip portion having a point, the point having a point angle, wherein the helix angle and point angle are both determined by reference to rotational axis, and the point angle is about equal to or less than the helix angle.
Abstract:
The present invention provides a timber structural member comprising: a first timber round having a first cooperating surface extending longitudinally along the length thereof, a second timber round having a second and a third cooperating surfaces extending longitudinally along the length thereof, and a third timber round having a fourth cooperating surface extending longitudinally along the length thereof wherein, the first cooperating surface is shaped to cooperate with the second cooperating surface, and the third cooperating surface is shaped to cooperate with the fourth cooperating surface, the first, second and third timber rounds are secured together to form a structurally integral unit in which the first cooperating surface is in contact with the second cooperating surface, and the third cooperating surface is in contact with the fourth cooperating surface, and the first, second and third timber rounds are substantially parallel to each other, and wherein the first, second and third timber rounds are secured to each other by a plurality of fasteners spaced along the length of the member, the plurality of fasteners comprising fasteners provided at both acute and obtuse angles from a longitudinal axis of the structural member, the fasteners extending through the first, second and third timber rounds.
Abstract:
The present invention relates to habitable building construction and in particular, the use of sensors in connection with engineered timber components of buildings, and the post- construction monitoring of sensor output. A timber-based building product is provided having one or more sensors, each of the sensors being configured to sense a characteristic of the building product or the environment thereabout and output a sensed condition by way of an electric or electronic output signal.
Abstract:
The present invention is directed to the field of building construction, and particularly the construction of multistorey buildings using timber as a major structural material. The invention is embodied in one form as a connector plate having a series of pins extending therefrom. In a building component, each pin engages with a relatively small diameter timber flanges by way of an axial bore hole formed in each flange. In this way, the flanges form a timber structural member useful in the formation of a framework of a building structure. The plate of the connector provides means for fastening to other similar connectors or to other building structures. Various combinations of connectors and building flanges may be used to construct a single storey building, and furthermore may be used in the construction of a multistorey building.
Abstract:
A timber structural member comprising: first, second and third timber rounds secured to each other by a plurality of fasteners spaced along the length of the member, the plurality of fasteners comprising fasteners provided at both acute and obtuse angles from a longitudinal axis of the structural member, the fasteners extending through the first, second and third timber rounds, wherein the timber structural members are connected to each other by the end faces, and wherein the extended span timber structural member comprises: a connecting member, and a continuous recess formed across two abutting timber rounds, the connecting member being seated in the recess thereby straddling the abutting end faces of the two timber rounds, and wherein the extended span timber structural member comprises fasteners inserted at joins toward the ends of a composite structural member, the fasteners from a lateral view point forming an inverted V arrangement.
Abstract:
ABSTRACT The present invention provides a timber joist comprising first and second flanges connected together by a web, the web being structurally integral with the flanges. Both flanges comprise timber poles. The web inserts into the first and second flanges a sufficient distance so as to provide resistance to longitudinal splitting or cracking of the timber.
