摘要:
The invention is a structural connector used as a component to construct an arch consisting of a plurality of closely adjacent, polygonal rows of stringer beams. The multiple row polygonal arch is a low-cost, general purpose support structure for bridges, shelters and arbors applicable to many cost-, time- or environmentally-sensitive situations. The invention is a Y-shaped connector, typically made of sheet metal, with three brackets, two upper brackets and a lower bracket, which collectively enable a union of three beams forming one node of the multiple row polygonal arch. Using these Y-shaped connectors to join the beams at each node creates the arch structure, and additionally provides the features of cantilevering, modularity, generic component shape, reusability and safety. The invention is applicable to a variety of structures such as: pedestrian and vehicular bridges, shelters, arbors, as well as jewelry, furniture and toys.

An apparatus for supporting brace members between a plurality of adjacent parallel spaced apart joists wherein each of the joists extends between top and bottom edges comprises a joist engaging cup adapted to receive one of the top or bottom edge of the joist therein and a brace supporting platform angularly extending from each side of the cup in a direction towards the other of the top or bottom edge of the joist. A plurality of brace members may be sized to be received on the brace supporting platforms and extend diagonally between a top and bottom edges of adjacent joists.

A staple includes a length of metal wire shaped to form a crown and two spikes. Each spike depends from a respective end of the crown and includes a shoulder at each end of the crown, a sharpened tip portion and an elbow interposed between each tip portion and shoulder, the elbow comprised of a proximal limb and a distal limb such that the tip portions depend from respective distal limbs. An included angle between each shoulder and the crown is between about 91° and 96°, an included angle between each proximal limb and the crown is between about 60° and 85° and an included angle between each distal limb and the crown is between about 95° and 130°.

A fixing tool (5) for fastening of building framework members comprises a plate (6) attachable on a first framework member (1), the first transverse edge (4) of which plate has an abutment member (7) for the supporting of a second framework member (2) that is intended to be fastened on the first framework member (1). The plate (6) has fixing members (10, 12, 13) engageable in said first framework member (1) as well as a removal member (8) for the removal of the fixing tool (5) when said second framework member (2) is fastened to said first framework member (1). The invention also relates to a method where the fixing tool is used in the fastening of building framework members by the fact that the same is placed on a first framework member connecting to the intended position of a second framework member, and the fixing tool is fastened on said first framework member by the fact that the fixing members included in the fixing tool are driven into the surface of the first framework member, whereupon the second framework member resting against the abutment member of the fixing tool is fastened to said first framework member, whereupon the fixing tool is removed from said first framework member by applying a force to the removal member.
摘要:
An adjustable nogging is formed by selecting a length of timber (10) appropriate to the spacing of two members between which the nogging is to extend. Metallic connectors (20) are secured to the end faces (17, 18) of the length of timber and then that length is divided into two pieces (22, 23) by way of a diagonal cut extending from one side of the length of timber at one end region (5) thereof to the other side of the length at the other end region thereof. The total length of the divided timber is adjusted by relative sliding movement of the two pieces (22, 23), with the cut faces in sliding engagement. Thereafter, the two pieces are secured together with hot-melt adhesive but possibly also or instead nails or screws, when the total length of the resultant nogging is that required (10) for the installation.
摘要:
A connector (20) for joining a timber member (10) to a second component has an end plate (21) for overlying an end face of the timber member (10), the end plate (21) having projecting prongs (27) for penetrating the end face of that member. The connector (20) has a first side tab (22) adjoining the end plate (21) along a first common edge whereby the first side tab (22) may be bent round (5) about that common edge to engage a first side face (11) of the timber member following engagement of the end plate with the timber member end face. The first side tab (22) has projecting teeth (30) for penetrating the first side face (11), the teeth (30) being curved along their length towards the end plate (21) of the connector (20). A second side tab (23) is similarly formed to the first side tab (22, 10) and adjoins the end plate (21) along a second common edge opposed to the first common edge, for bending round to engage a second side face (12) of the timber member.

In one aspect the invention comprises an elongate narrow web (302) for securement to a top or bottom plate edge or face edge of a wall panel, a plurality of elongate planar tie elements (303, 305) extending from opposed edges of the base web in a direction normal to said base web, said ties arranged in pairs with the ties of each pair located directly opposed across an elongate channel, the ties being spaced at intervals along said channel. Also disclosed is a joist hanger (Figure 9); joist hanger bracket (Figure 4, item 409); method of building construction (Figure 17); a ventilation packer (Figure 2c); a corner arrangement (Figure 6).
摘要:
The invention provides a connector (10) for connecting two lengths of timber brandering (36 and 38) end-to-end in a roofing structure. The connector (10) comprises an elongate, hollow sleeve (12) which is sized and shaped to receive a length of timber brandering (36 or 38) of generally square cross section at each longitudinal end (28 and 30) thereof, and which includes a pair of inwardly directed gripping formations (20 and 22) for gripping brandering of various different cross-sectional dimensions within a predetermined tolerance by engaging or deforming the brandering. A web or flap (34) is provided approximately midway along the length of the sleeve (12) for limiting the extent to which brandering may be inserted into the sleeve from each longitudinal end (28 and 30) thereof. The sleeve (12) also includes two apertures (44) for allowing the brandering to be locked in position within the sleeve with locking pins or nails (45).
摘要:
An attachment system and method for coupling a wall (14) and a floor (18) together during and/or after construction, and for facilitating final orientation of the wall and floor, includes first and second members (32, 34) coupled to the respective wall and floor and pivotal about a hinge member (36). The wall and floor, and thus the first and second members, pivot between an assembly position, and a final position. The system can include a strap (40) defining the first and second members, and the hinge member. In the assembly position, the wall or the floor is assembled, and the first and second members are coupled to the respective wall and floor. In the final position, the wall and floor are finally oriented with respect to one another. A fastener (60) can extend through the first and second members in the final position. A concrete anchor (84) can be attached to the second member and can be inserted into a concrete.
