Description

[Detailed Description of the Invention] The present invention relates to a metal fitting used for joining wooden members of a wooden building.

Traditionally, wooden frame buildings had various construction methods for joints and joints, and these had to be processed at the construction site, which had the disadvantage of prolonging the construction period. Therefore, in recent years, wooden components and their joining structures have been standardized, and the processing of joints, joints, etc. is carried out intensively in factories, and these processed wooden components are joined using joining fittings at the construction site. The wooden shaft construction method is used.

However, the joining fittings used in this wooden shaft construction method are secured to the wooden components by passing bolts, etc. through through holes provided in the joining fittings and holes provided in the wooden components. . Therefore, when joining wooden components, it is necessary to align the holes in the wooden components and the through holes in the joining fittings at the construction site, then insert bolts, etc. into these holes, and then tighten them several times. Therefore, from the perspective of improving the efficiency of work at the construction site, there was still room for improvement in the joining metal fittings.

The present invention was developed in view of the above circumstances, and all processing necessary for joining wooden parts is done in advance in a good working environment such as a factory, and the wooden parts are assembled at the construction site and the joining metal parts are assembled. The purpose of the present invention is to provide a joint fitting suitable for a new wooden shaft construction method, which allows buildings to be assembled with the simple work of fitting.

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

FIG. 1 shows a perspective view of an embodiment of the joint metal fitting for a wooden building according to the present invention. In the drawings, reference numeral 1 denotes a penetration portion, which is formed from a flat plate into a substantially T-shape. This penetration part 1 is located at the lower part of the central long part 2.
A central fitting groove 4 with sliding portions 3 inclined inward from both sides is formed, and protruding portions 5a, 5 on both sides are formed.
A side fitting groove 7a, which is provided with a sliding portion 6a, 6b that slopes inward from one side, is provided at the lower part of each of b.
7b. Moreover, the upper part of the penetration part 1 is
A presser piece 8 is formed by bending forward with the same width.

Note that the hole 9 drilled in the center of the upper part of the penetration part 1
is a bolt hole, which is used when the joint metal fitting of the embodiment is used in combination with other joint metal fittings, as will be described later.

FIG. 2 is a perspective view of an example in which the joining fitting of the above embodiment is used to join the girders 12a and 12b on the upper surface of a column 11, and FIG. 3 is a side perspective view thereof. In this connection example, the upper part of the column 11 and the girder 12a, 1
A penetration groove 13 formed by a saw blade is formed in advance at approximately the center of the joint portion of the column 2b, and a bolt 14 is provided in the column 11 to pass through the penetration groove 13 from the upper side surface thereof.
Bolts 15a, 15b are provided on the beams 12a, 12b, passing through the penetration grooves 13 from the side surfaces of the joints. The upper part of these pillars 11 and girders 12a, 12
All processing for the joint part b is performed in a good environment such as a factory. Therefore, at the construction site, the girder 12a,
12b are brought into contact with each other, and the penetration part 1 of the joining fitting is fitted into the penetration groove 13 which has become an integral part. Then, the central fitting groove 4 of the penetration part 1 is fitted with the bolt 14 of the pillar 11 while being guided by the sliding part 3, and the side fitting grooves 7a and 7b are guided by the sliding parts 6a and 6b, respectively. It fits with the bolts 15a and 15b of the girders 12a and 12b, and the column 11 and the girder 12
a, 12b are firmly joined. In this case,
The holding piece 8 may be fixed with a nail.

FIG. 4 is a perspective view of an example in which girders 12a, 12b, and 12c are joined in a T-shape by combining the joining fittings of the present invention and other types of joining fittings. In this case, as shown in Figure 2, the girder 1 can be
After joining 2a and 12b, a bolt 16 is passed through the hole 9 of the penetration part 1, and a different type of joining fitting 17 is attached.
Insert the girder 12c here and connect the girders 12a, 12b,
Assemble 12c into a T-shape.

As described above, according to the present invention, all processing necessary for joining wooden parts is performed in a good working environment such as a factory, and the wooden parts are assembled at the construction site and the joining fittings are inserted. Buildings can be assembled with just a few simple tasks, and the efficiency and safety of assembly work at the construction site can be improved. Further, the structure of the joining fitting is simple, easy to manufacture, and easy to handle, which has excellent practical effects.
