Description

[Detailed description of the invention] This invention is a connecting fitting for wooden structures that is installed at the joint between a vertical member such as a column and a horizontal member such as a wooden stand, and connects the vertical member and horizontal member. Related: In particular, the present invention relates to a connecting metal fitting in a wooden structure that can easily obtain fixing precision of the metal fitting.

Conventionally, when connecting vertical members such as columns and horizontal members such as foundations in wooden structures, wooden structures made of various shapes were used to prevent the strength of the vertical and horizontal members from decreasing by creating slots, grooves, etc. Connecting metal fittings are often used.

However, when installing the above-mentioned conventional connecting fittings, the connecting fittings were simply brought into contact with the joint between the horizontal member and the vertical member and fixed by driving a nail, etc., which often caused the connecting fittings to be displaced. There was a problem in that the predetermined connection strength could not be obtained because the connectors were fixed in the same state.

This invention was devised in view of the current situation, and its purpose is to provide marks on both sides of the connecting fittings to maintain the levelness of the connecting fittings, and to By arranging a cut-and-raised nail for temporary fixing on the back side of the metal fittings, which also serves as a mark for the verticality of the connection metal fittings, it is possible to connect horizontal and vertical members with the specified connection strength without displacing the metal fittings. The present invention aims to provide a connecting fitting in a wooden structure that can be connected.

The details of this idea are explained below based on the Zushi example in the attached drawings! I will explain this.

As shown in Figure 1 and Figure 4', the connecting metal 47g and + metal fitting main body 2 of this embodiment have a substantially triangular shape or a dowel shape, and are attached to the center vertical line of the main body, that is, the mounting It is formed symmetrically about the vertical reference line.

(The main body of the lever, both sides □ 3, 4 are cut inward from the approximately 1-shaped armrest main body 2.
The horizontal reference point for attaching the bending point P, ・PゝS connecting fitting 1φ is used as the seed coat.

Further, on the upper part of the main body 2, in the central part thereof, there are cut and raised claws 5, 6 that protrude from the front side 2a of the main body 2 toward the back side 2b.
are formed, and the lower ends, which are the apexes of the cut-and-raised openings 7 and 8, constitute a vertical reference line for the connection fitting 1.

A claw piece 9 is provided protruding from each corner of the back side 2b of the main body 2.

In addition, the reference numeral 10 in FIGS. 1 to 4 indicates holes for nail insertion, respectively.

Next, a method of attaching the connecting fitting 1 according to the above-mentioned actual example will be explained.

First, both horizontal reference points P, P of the connecting fitting 1 are aligned with the top surface of the horizontal member 11 such as a base so that they are on the same line, and a vertical reference line q drawn in advance on the vertical member 12 such as a column is aligned.
and the lower ends of the cut-and-raised openings 7 and 8 of the connecting fitting 1, and then hit the connecting fitting 1 with a hammer or the like from the front side 2a of the connecting fitting 1, so that the cut-and-raised claws 5, 6 and the claw pieces 9 The vertical member 12 and the horizontal member 11 are inserted into each other, and the connecting fitting 1 is temporarily fixed at the joint between the horizontal member 11 and the vertical member 12.

After this, by driving a nail into the hole 10 of the connecting fitting 1, the connecting fitting 1 is firmly fixed at the joint, and both the members 1
1. Connect 12.

Since this invention is configured as described above, when horizontal and vertical members are attached on one side of each member, the horizontal and vertical alignment can be performed reliably and easily.

Therefore, the connecting fittings are placed in the predetermined positions of the horizontal and vertical members,
Since the connecting fittings can be easily installed without being displaced, the connecting strength capacity of the connecting fittings can be fully utilized, and the provision of temporary fixing claws makes it convenient for work such as nailing. play.
