Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a connecting device for wood, and more particularly to a device for connecting ends of wood in beams, shears, girders, foundations, etc.

[Conventional technology and its problems]

Conventionally, the ends of the wood that forms the main framework of beams and the like have been connected by machining them into complicated shapes and fitting them together, as shown in FIG. However, this method was complicated, required skill, and was inefficient, meaning that only about three sets could be made in a day.

For this purpose, the applicant has registered Utility Model No. 1568362.
We are proposing a connector that is easy to connect and has high strength after connection.

However, since this connector can only be used for linear connections, there is no easy method for connections with complicated shapes such as L-shapes, T-shapes, and X-shapes.

Furthermore, it has been difficult to manufacture the above-mentioned connector at a low cost due to its manufacturing process.

[Means for solving problems]

It is an object of the present invention to solve the above-mentioned problems and provide a connector that is inexpensive and easy to connect.

That is, the substrates 1 and 15 consist of a vertical part and a horizontal part.
The first insertion portions 7, 25 constituted by the horizontal arm plate 1- of the first insertion portions 7, 25.
1, 1-2, 15-1 by bending the upper side thereof at right angles to the first insertion portions 7, 25; 1
The first exposed portion 3, 4, 1 is located at the back of the notch made at the tip of the bent line.
7 at right angles to the arm plate side, and the arm plates 1-1, 1-
2, the tip portion of 15-1 is connected to the first exposed portion 3,
4, 17 and the first exposed portion 3,
a second insertion part 5, 6, 18 formed by bending it so as to be flush with the bent part at the tip of 4, 17, and welding the joint of both of these bent parts;
The side portions of the vertical portions of the first insertion portions 7, 25 are configured to form second exposed portions 11, 21 by making cuts 12, 22 so that they can be bent on site at right angles to fit the combined wood. This is what I did.

The horizontal portion of the substrate 1 is provided on both sides of the vertical portion and is formed in a T-shape, and the first exposed portions 3 and 4 on both sides are bent in opposite directions. In some cases, the horizontal part is provided on one side of the vertical part and formed in an L-shape.

[Effect]

There is no need for the conventional complicated connection work, and the connection can be made simply by making cuts for each insertion part.

A second insertion portion 5 is formed. With a similar structure, a second arm plate 1-2 and a second
The insertion portion 6 is formed. Among the first and second arm plates 1-1, 1-2, the first exposed portion 3,
4, the remaining parts excluding the insertion parts 5 and 6, and the third arm plate 1-3 form the first insertion part 7. Both sides of the third arm plate 1-3 of this first insertion portion 7 are made of wood 8,
9, 10 are provided with a second exposed part 11 for on-site bending, which is bent to match the timber 8 of the vertical part after insertion, and a notch 12 to enable this bending. In addition, in order to strengthen the connection after inserting into the wood, the first exposed parts 3, 4 and the second exposed part 1 are
1 is provided with a nail hole 13, and the first insertion portion 7 is provided with a bolt hole 14.

(2) Second Embodiment FIG. 5 is a perspective view of a connector according to a second embodiment of the present invention, and FIG. 6 is a developed view. A first arm plate 15-1 in the horizontal part of one L-shaped board 15 consisting of a vertical part and a horizontal part extending to one side, and a second arm which is a vertical part extending in a direction perpendicular to the first arm plate 15-1. A first exposed portion 17 is formed on the plate 15-2 side (upper side) by being bent at a right angle on a straight line 16.
Furthermore, the tip of the first exposed portion 17 is connected to the straight line 1.
The first arm plate 15 is bent so that the notch portion provided at the end of the arm plate 6 is bent at right angles to the first arm plate 15-1 side, and is in a plane state with this.
-1 is bent at right angles to the side opposite to the first exposed portion 17, and the bent portion and the bent portion of the first exposed portion 17 that is in contact with the bent portion are welded into one piece. A second insertion portion 18 is formed. In addition, the side of the second arm plate 15-2 on the first arm plate 15-1 side is attached to the vertical portion of the wood 20 after being inserted into the wood 19, 20 at the site.
A second exposed portion 21 for on-site bending and a notch 22 to enable this bending are provided. Note that nail holes 23 are provided in each of the first exposed portion 17 and the second exposed portion 21 in order to strengthen the connection after insertion into wood.
