Description

[Detailed Description of the Invention] The present invention relates to a joining member for joining structural members in a building.

When constructing a building such as a house, the structure,
For example, wood joints were generally carved by carpenters to join the pillars together. However, this work is tedious, time-consuming, and requires skill, leading to higher housing costs.

As a conventional example of solving this problem,
There are those shown in the publications No. 8237 and Utility Model Publication No. 51-11213.

The former conventional example is as shown in FIG. The ends of c and d are respectively bent outward at a substantially right angle to form receiving pieces e and f, and one receiving piece e of the above two receiving pieces e and f is cross-coupled. The receiving piece f is connected to the upper side of one of the pillars g, h, and the receiving piece f is connected to the lower side of the other pillar h, respectively.

In the latter conventional example, as shown in Fig. 2, a metal plate is made flat to cover one side of the pillar g' of one of the cross-coupled pillars g' and h', leaving one side of the pillar g' and covering the other three sides. It is bent into a shape to form a front part i and both side parts j and k, and the lower half parts of both side parts j and k are bent outward at right angles to this side part to form flat parts l and l'. and the above-mentioned front part i, both side parts j,
It has a structure in which an appropriate number of nail holes are provided in k and flat plate parts l and l', and the flat part is connected to one pillar g' that cross-connects, and the front part i and flat plate parts l and l' is connected to the other column h′.

Of the above two conventional examples, the former conventional example
-8237), the dimension between the upper surface of one pillar g and the lower surface of the other pillar h of two pillars g and h that cross-connect the spacing m between two receiving pieces e and f. If the dimensions of one of them do not match, insert shims between the receiving pieces e, f and the pillars g, h, or replace the pillars g, h. There is a problem in that on-site processing such as cutting is required, and in addition, each joining member can be joined only on one side.

In addition, in the latter conventional example (Utility Model Publication No. 51-11213), the inner dimensions of both side surfaces j and k of the planar shape section must be shaped to fit into the column material g' without any gaps. However, there were problems in that dimensional control was difficult, and since there were many bent pieces, a large number of man-hours were required for the molding process.

The present invention was developed in consideration of the above, and two sides of each of the cross-connected pillars with a rectangular cross section are integrally wrapped, and a single joining member with a simple shape is sufficient. Even if there is an error in the cross-joint parts of the pillars or in the shape of the joining members, the joining members can be joined without any problems, and the work of joining the joining members is easy. The object of the present invention is to provide a joint member for construction, which can be efficiently performed without requiring on-site processing, and which can be formed in fewer steps.

Embodiments of the present invention will be described below with reference to FIGS. 3 to 7.

3 to 5 show a first embodiment of the present invention. In the figures, 20 is a joining member, and this joining member 20 consists of two pillars 21, 21 having a square cross section that butt and intersect. It consists of an L-shaped portion 20a that envelops two sides of one of the pillars 21, and two tongue pieces 20b and 20c that abut each of the two sides of the other pillar 22. One of these two tongues 20b, 20c is flush with one side of the L-shaped portion 20a, and the other is bent and formed against the other side of the L-shaped portion 20a. .

The joining member 20 is developed as shown in FIG.
By concavely bending the material along 3, a simple rectangular material is formed in one motion and subjected to anti-rust treatment to become a product.

FIG. 5 shows a state in which a large number of the above-mentioned joining members 20 are stacked, and the corresponding front and back surfaces, that is, the corresponding bent pieces, are brought into contact with each other to form a compact stack.

6 and 7 show a second embodiment of the present invention. In the figures, 30 is a joining member, and this joining member 30 is made up of two pillars 2 that butt and intersect.
1 and 22, which encompasses two sides of one of the pillars 21.
It consists of an L-shaped part 30a and a second L-shaped part 30b that embraces two sides of the other square timber 22.
The L-shaped portions 30a and 30b are connected at one side of each L-shaped portion.

The joining member 30 is developed as shown in FIG.
3. Concavely bend and shape.

As shown in FIGS. 3 and 6, the above-mentioned joining members 20 and 30 pass through holes 12 provided on each side of the pillars 21 and 22, which are butted and intersected, respectively, in a state of enclosing two sides of each side. It is fixed with a fixing device such as a nail.

At this time, each joining member 20, 30 is connected to each column member 2.
The joint members 1 and 22 are pressed against each other from one side, and molding errors in the joint members 20 and 30 are hardly a problem.

In the above embodiments, the bending angles are all 90°, but depending on the cross-sectional shape of the square timbers and the intersection angle of the square timbers, angles other than 90° may be used.

The material of the joining members 20 and 30 is usually metal, especially steel plate, but is not limited to this. For example, it can be injection molded into a predetermined shape at once, or hard plastic molded by bending from a plate material. It may be a product. Furthermore, the pillar materials to be joined are not limited to wood.

Note that the joining members 20 and 30 according to the present invention have sufficient strength even with just one, but if necessary, two joining members 20 and 30 may be used on the front and back sides.
May be used individually.

The present invention is as described above, and the first member is formed by bending and forming into an L-shape two pieces that embrace the two sides of one of the two pillar members 21 and 22 that are cross-coupled and have a rectangular cross section. and the pillar members 21, 2 which are integrally connected to the first encasing part and cross-coupled with each other.
2. In the architectural joint member consisting of a second wrapping part having two pieces that wrap two sides of the other pillar 22, one of the two pieces of the second wrapping part. One piece member is bent and integrally connected to one end in the bending ridge direction of one piece member of the first wrapping part, and the other piece member is on the same plane as the other piece member of the first wrapping part. Since the architectural joint members are constructed by positioning them in
Two sides of each of the cross-coupled portions are integrally wrapped, and the two pillars to be cross-coupled can be wrapped and coupled with sufficient strength using one joining member 20, 30. Particularly, according to the present invention, since the joining member can be pressed and joined from one side of the cross-joined portion of the cross-connected pillar members 21 and 22, the joining member 20 and 30 or the pillar member 21, To be able to connect joining members 20 and 30 without any problem even if there is a temporary dimensional error in a cross joint part of 22, and to perform the joining work of joining members 20 and 30 efficiently without requiring on-site processing. Can be done.
