JP 10-33260 A

  The connecting hardware is accurately attached to the main member in advance at the factory, transported to the construction site in that state, and connects the main member and the coupling member to each other at the construction site. The above-mentioned connecting hardware is formed by integrally forming a support plate and a joining plate by bending a single iron plate into a U-shape, so if it is only attached to the main member at the factory, it will be used at the construction site. Each member can be easily connected to each other simply by joining the connecting member to the member and fixing it to the connecting hardware with a pin. However, if the connecting hardware is attached to the side of the main member, the protruding length of the connecting hardware from the main member There was a problem that the bulkiness increased and the transportation cost for transporting the member from the factory to the construction site was very high. In addition, since the connecting hardware is an integrally formed product, it is necessary to manufacture various types of connecting hardware according to the size of the coupling member, and there is a problem in that the manufacturing cost increases.

Furthermore, since the connection hardware is attached to the main member in advance at the factory as described above, it cannot be attached across a plurality of main members. For example, when connecting the end of a beam that is tall from the side to the part that connects the column and the torso to join, the connecting hardware cannot be attached across the column and torso, and the beam The height of the torso is matched to the height of the body. However, since the torso is received by a pillar in the middle, there is no problem in strength even when using wood whose height is lower than that of the beam. In other words, in order to consider the ease of attaching the connecting hardware first, the cost of the wood was somewhat sacrificed.
In addition, in the latest CAD / CAM system, information on connecting hardware is input, and when the assembly drawing of the housing is drawn, which connecting hardware is used in which part of each member and what mounting hole is provided in each member. Recognizing whether it has to be machined, uniform hole machining is automatically performed on each member. However, depending on the individual wooden construction, the thickness of the tatami mat placed on the floor may be different, or the flooring may be different, so you may want to change the height of the beam attached to the pillar up or down. In order to change the machining position of the hole in response to the change, it is necessary to manually input new information each time, which is a very hard work and also causes a reduction in work efficiency.

  Therefore, the present invention can reduce the bulk when transporting a member with a connecting hardware attached to the side from the factory to the construction site, and improve the effectiveness and economic efficiency of the wooden frame.
