Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint structure between a pillar and a beam in a wooden building, and a hardware used for forming these joints, and a wooden building using the joint structure. Is also disclosed.

[0002]

In the conventional construction method of wooden construction, pillars are erected, and beams are attached to the pillars to form a framework. In recent years, the two-by-four construction method is also popular.

[0003] However, in the conventional method, since the pillar and the beam are not framed by the tenon of the pillar and the beam, a skilled carpenter is required and it is troublesome.
In addition, natural wood is used for the pillars and beams, but there is also a problem that if the drying is not sufficient, the framework will be disordered after construction. Furthermore, there is a fundamental problem in that long natural materials are difficult to obtain themselves, and that the deviation is large. On the other hand, in the two-by-four construction method, it is necessary to use a large amount of joint hardware for the framework, and there is a problem that the operation is troublesome.

[0004] There is also a construction method of constructing a framework with a lightweight steel frame. However, in general, the length of the steel frame is a standard product, and it is difficult to form a large span framework by skipping columns. Therefore, even if this method is used, a free space cannot be formed.

The present invention is intended to solve the above-mentioned problems of the existing construction methods, and is a framework that can be easily constructed and can form a large span space, and a wooden building using the same. It is another object of the present invention to provide hardware used in the framework.

[0006]

According to the present invention, in order to achieve the above-mentioned object, in order to achieve the above-mentioned object, a column contact surface with respect to a column, a vertical surface which rises vertically from the center of the column contact surface as a single unit, and the column contact surface And, for a beam hardware consisting of a beam receiving surface provided below the vertical surface, a steal is provided at a position where the column contact surface of the column is joined, and the column contact surface is bolted against this steal, The beam is formed with a groove corresponding to the vertical surface, and the vertical surface is inserted into the groove and bolted to form a column-beam joint structure. In addition, the hardware for beams used here is also used independently. further,
As the configuration of the column contact surface and the vertical surface, a T-shaped steel obtained by cutting a web of H steel may be used.

[0007] Since the column contact surface and the vertical surface are integrally formed without a seam, it is possible to firmly cope with the stress received from the torsion of the column and the beam after the construction. On the other hand, the beam receiving surface will be used for the temporary construction of the beam at the time of construction, and will perform a complementary function after installation. The means of forming the column contact surface and the vertical surface by cutting the H steel web can contribute to simple production.

Further, in the wooden building according to the present invention, a means for forming a skeleton by adopting the following standing structure of column bases at the same time as the joint structure of the column beams is used. In other words, the upright structure of the column base is a column upright fitting in which the opening of the U-shaped channel steel is closed from the center of the horizontal surface by the horizontal surface portion of the T-shaped steel with the vertical surface seamlessly integrated, The vertical surface of the T-shaped steel was fixed upward on a concrete foundation, and the vertical surface was inserted into the groove formed in the column and bolted.

According to the wooden building by the means, in addition to the joint strength of the column and the beam by the joint structure of the column and the beam, the U-shaped channel steel in the standing structure of the column base functions as a base for fixing to the foundation. In addition, since the seamless vertical surface of the T-shaped steel sufficiently responds to stress such as torsion, the joining strength itself to the column foundation will also increase, and the synergistic effect of these column-beam joint structures and column base standing structures The action can further increase the overall strength of the wooden building.

[0010]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows an embodiment of a wooden building according to the present invention.
Reference numeral 1 denotes a column made of a laminated material or a laminated material, 2 denotes a beam also made of a laminated material or a laminated material, 3 denotes a metal fitting for joining the column 1 and the beam 2, and 23 denotes a metal fitting for standing a pillar. In this embodiment, the pillars 1 and the beams 2 are made of laminated wood or laminated material. However, since the laminated wood or laminated material has less deviation from natural wood such as hinoki wood and has a strong strength, This is because a large span building is possible. However, it goes without saying that the present invention can be applied not only to these laminated materials and laminated materials, but also to the construction of hinoki materials and rice pine used in the conventional method. In addition, although the metal fittings 3 for beams are seen only in one direction in the figure, it is natural that all of them are installed in the direction in which the beams 2 are joined to the columns 1.

FIG. 2 is an overall perspective view of the hardware 3 for beams.
4 is a column contact surface, 5 is a vertical surface, and 6 is a beam receiving surface. The pillar contact surface 4 has bolt holes 7 for joining to the pillar 1.
7 are drilled, and bolt holes 8.8 for joining to the beam 2 are drilled in the vertical surface 5. In order to secure the joint strength of the column and the beam, the beam fitting 3 has a column contact surface 4 and a vertical surface 5 which are integrally formed without a seam, and a beam receiving surface 6 is welded to the bottom. I have. The column contact surface 4 and the vertical surface 5 may be formed by cutting a T-shaped steel material to an appropriate length. However, as shown in FIG. It is also possible to use the web 9 as a vertical surface and the flange 10 as a column contact surface after forming the steel shape. In the case of small-scale production, it would be preferable to use an existing H-rich steel, and in the case of mass production, it would be preferable to directly produce a T-shaped steel material. FIG. 4 is an exploded perspective view of the beam hardware 3, and a portion 13 indicated by a dotted line of the beam receiving member 12 is welded to the bottom of the T-shaped steel member 11.

Here, the reason why the column contact surface 4 and the vertical surface 5 are seamlessly integrated and the beam receiving surface 6 is welded to the column contact surface 4 is that the column / beam is joined with the beam fitting 3 of the present embodiment. In this case, stress is applied in the direction of pulling and twisting, so that the strength of the column contact surface 4 and the vertical surface 5 must be sufficiently high. However, once the beam is joined, a large vertical load is applied to the beam receiving surface 6. Because it does not start. That is, the beam receiving surface 6 contributes to the temporary installation of the beam when the beam is bridged during construction,
After bolting the beam 2 to the beam hardware 3, the beam receiving surface 6 functions complementarily.

FIG. 5 is a view for explaining a process when the beam 2 is joined to the column 1 using the beam hardware 3. First, a portion 14 of the column 1 with which the column contact surface 4 of the metal fitting 3 comes into contact is formed with a steal 14 by the area of the column contact surface 4 and the thickness of the column contact surface 4. This is to improve the behavior of the hardware with respect to the pillar 1. Then, the column contact surface 4 is accommodated in conformity with the stealing 14, and is fixed with a bolt. Next, a groove 16 for vertically inserting the vertical surface 5 from the connection 15 of the beam 2 is cut, and the groove 1 is formed.
The beam 2 is placed on the beam receiving surface 6 while inserting the beam 6 into the vertical surface 5, and is positioned and then bolted. This completes the strong column / beam joining. As described above, in the present embodiment, it is not necessary to penetrate the mortise as in the conventional method, so that the strength of the member itself is not significantly reduced, and the joints are bolted, so that the strength is sufficiently ensured.

Next, the standing structure of the column base will be described with reference to FIG. In FIG. 1, 21 is a concrete foundation, 22 is a base placed on the foundation 21, 23 is a metal fitting for pillar erection showing the present embodiment, and 24 is a metal for fixing the metal erection to the foundation 21. Anchor bolt. FIG. 6 shows a perspective view of the pillar mounting hardware 23. Here, reference numeral 25 denotes a rib for fixing the column, and a groove 26 formed on the base surface of the column 1 is inserted into the rib 25, and bolting is performed to complete the start-up of the column 1. As shown in FIG. 7, the pillar mounting metal 23 is manufactured by welding a U-shaped channel steel 27 and a T-shaped steel 28.
Even in this case, the T-shaped steel 28 can be used by cutting the web of the H steel. Also, in order to secure strength against stress such as torsion,
There is no difference from the above-mentioned form of the metal fitting that the T-shaped portion needs to be integrated without a seam. In addition,
From the viewpoints of securing strength and accuracy, the columns are more preferably glued laminated materials or laminated materials, as in the case of the column / beam joint structure.

[0015]

According to the present invention, since the joint structure of the column and the beam is achieved by using the metal fittings for the beam, it is strong against torsion after the construction, is weak against the torsion as in the conventional method, and has a problem in the joint strength. The defect that there is can be avoided. Also,
When glued laminated materials or laminated materials are used as wood, the effects of the present invention can be synergistically exhibited, and a lightweight and strong skeleton can be formed, so that a large span structure can be easily provided. It becomes possible. Further, in the example in which the H-shaped steel is used as the base material and the T-shaped steel is used, the members can be easily produced.

Further, at the same time as the column-beam joint structure,
The column-equipped metal fitting in which the opening of the U-shaped channel steel is closed from the center of the horizontal surface to the horizontal surface of the T-shaped steel with the vertical surface seamlessly integrated, and the T-shaped steel Since the vertical surface was fixed upward, and the vertical structure of the column base that was bolted by inserting the groove engraved in the column to this vertical surface, the frame of the wooden building was constructed, It has become possible to provide wooden buildings that are superior in seismic strength compared to wooden buildings.
