[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention is mainly used as a metal member for forming a joint, which joins horizontal members such as beams or girders of a wooden building, and pipe columns or through columns.

[0002]

[Prior art]

 Since it uses mortises, mortises, and spigots, it is complicated to process, and despite the large number of shapes and sizes, it is not used according to the strength required by scientific calculation, but rather the shape of the joint according to experience. It took many years to acquire skills because the size and size were selected, and there was concern about the strength of the joint. .

[0003]

[Problems to be solved by the device]

 The strength can be calculated by the officially accepted allowable stress degree and calculation method, and it has the strength that can be widely supported even with simple shape parts and processing, even if there are few types of shape and size, mass production What is possible.

[0004]

[Means for Solving the Problems]

 A tubular member having a rectangular cross-section for connecting the load transmitting side member and the load transmitting side member, which is composed of one bottom portion, two wall portions, and one upper portion, and each of the above-mentioned portions is rectangular and has a bottom portion and an upper portion. The wall part is formed at a right angle with respect to the boundary line, and depending on the part to be used, a bolt-through hole and a rectangular through-hole that penetrates the orthogonal wire rod are drilled. Joints between the bridge members, mutual vertical members, or horizontal and vertical members shall be formed.

[0005]

[Action]

 The strength of the joint can be calculated based on the tree structure calculation standard by using the allowable stress levels of the steel products, wood materials and their joints, which are stipulated in the building code legal system. Since it is tubular with a simple rectangular cross-section, it is easy to manufacture, and it is also a hole for other fasteners that are orthogonal to those for bolts. The horizontal material to be joined and the vertical material can be processed by using a commercially available power tool, such as a corner cutter, a router, and a drill. Due to the high strength of the finished joint, even small-sized hairpins are useful for joining relatively large members, so there are fewer types. By taking advantage of these simple shapes and the types that can be easily processed with few types, it is possible to mass-produce and supply inexpensive joints.
