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 timbers that form the main frame of beams and the like have been connected by machining them into complicated shapes and fitting them together, as shown in FIG. 10, for example. However, this method is complicated, requires skill, and is inefficient.
I was only able to make about three sets 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 connections in a straight line, there is no simple 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 the 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.

In other words, the first circuit board composed of one U-shaped substrate 1
an insertion section 1-1, and a first insertion section 1-1 formed by bending the upper side of the arm plate 1-2 on the lower side of the U-shape at right angles to the first insertion section 1-1. 1 and the U-shaped tip of the first exposed portion 2 at a right angle to the first exposed portion 2 at the back of the notch made at the tip of the bent line. Bend it toward the arm plate 1-2 side, and make the tip portion of the arm plate 1-2 opposite to the first exposed portion 2 and flush with the bent portion of the tip of the first exposed portion 2. The second insertion part 3, which is formed by bending the two bent parts together and welding the joints of both bent parts, and the tip of the U-shaped upper part of the first insertion part 1-1 are bent at right angles to the combined wood. The U-shaped vertical part of the substrate 1 has a second exposed part 5 which can be bent in the field, and the substrate 1 is at right angles to each other on the side opposite to the second insertion part 3 and the second exposed part 5. It is made by joining multiple pieces together so that it looks like this.

Note that depending on the shape of the wood to be connected, the plurality of boards may form a T-shape with three boards, or an X-shape with four boards.

[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.

(1) First Embodiment Figure 1 is a perspective view of a connector according to the first embodiment of the present invention, Figure 2 A and B are developed views, and A is a developed view of a single board; 1 is a developed view of a board in which the A's are connected in opposite directions.

A first insertion section 1-1 composed of one U-shaped substrate 1 shown in FIG.
A first exposed portion 2 formed by bending the upper side of the arm plate 1-2 on the lower side of the U-shape at right angles to the first insertion portion 1-1, and a tip portion of the first exposed portion 2. At the back of the notch provided in 2-1, bend the arm plate 1-2 at right angles to the first exposed portion 2, and fold the tip portion 1-3 of the arm plate 1-2 into the first exposed portion 2. It is bent at right angles to the opposite side, and the joint portion with the tip portion 2-1 is welded to form one sheet of the second insertion portion 3. Further, a second exposed portion 5 is formed by making a notch 4 in the tip of the upper side of the U-shaped substrate 1 so that it can be bent on site to match the assembled wood. The sides of the U-shaped vertical parts of the substrates 1 formed in this shape are welded together with the sides opposite to the second exposed portions 5, so that each substrate 1 is at a right angle. Configure. In this case, in this embodiment, the two substrates 1 on one plane are connected from the beginning as shown in FIG. It is constructed by welding the substrate 1 at right angles.

Note that nail holes 7 are provided in the first and second exposed parts 2 and 5 for fixing after connection.
A bolt hole 8 is provided on the second insertion portion 3 side.

FIG. 5 shows the state of notches and bolt holes being drilled in the preparatory work before connection. The numbers in this figure with a '' indicate that the corresponding numbered parts in the above figures are inserted.

(2) Second Embodiment FIG. 6 is a perspective view of a second embodiment of the present invention. In this embodiment, the second
The connected substrates 1 shown in the exploded view shown in FIG. and welded along the center line 6, and fixed so that the plan view forms an X shape. FIG. 7 is a plan view showing this state.

The insertion portions and exposed portions in this embodiment are the same as those in the first embodiment, so detailed description will be omitted.

FIG. 8 is a perspective view showing a state in which four pieces of wood 12, 13, 14, and 15 are connected, and after installation, they are fixed with nails and bolts using the nail holes 7 and bolt holes 8 as in the embodiment described above. is the same as

FIG. 9 shows the state of notches and bolt hole drilling performed in the preparatory work before connection, and the numbers '' in this figure are the same as those in FIG. 5.

[Effect of idea]

As mentioned above, the wooden connector of the present invention can not only be manufactured at a low cost due to the rationalization of the manufacturing process, but also
The work of connecting wood is easy, and the connection results are strong.
