Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building in which a horizontal structure such as a base, a pillar and a girder is connected by a joint.

[0002]

2. Description of the Related Art In a current wooden building, pillars, girders, and the like are connected by a so-called "cut structure". In the notch, a connecting groove is provided in a column, a spar, or the like, a protrusion that fits into the groove is provided at the tip of the spar, or the like, and the protrusion is inserted into the groove without gaps and connected. This connection structure requires a high level of specialized technology for the processing of cuts, and requires a great deal of time and labor, thereby increasing the construction cost. Furthermore, in the connection part where the highest strength is required, a structure in which a part of a structural material such as a pillar or a girder is cut out and connected, that is, a structure in which a part of the structural material is partially cut off, significantly increases the strength of the connection part. It is a cause of lowering. This structure reduces the vibration resistance of the wooden building.

In order to prevent such adverse effects, as shown in FIGS. 1 and 2, a construction joint for connecting a structural member 1 such as a column or a girder by inserting it into a connecting tube 3 has been developed. I have. In the joint 2 shown in this figure, since the distal end portion of the structural material 1 such as a pillar or a girder is inserted into the metal connecting cylinder 3 and connected, no labor for cutting is required. In addition, since the connection portion is put in the connection tube 3 and connected, there is an excellent feature that the strength of the connection portion can be considerably increased and the vibration resistance of the wooden building can be considerably increased.

[0004]

[0006] Despite the fact that the connecting portions of columns and beams can be made to have a strong structure, wooden buildings using joints having the structure shown in the above figures have not been widely used. that is,
This is because a joint having this structure requires a great deal of time and labor in a process commonly called “built-in”, and it is practically impossible to construct it.

[0005] The joint shown in the figure is constructed in the following steps. Stand pillars perpendicular to the foundation. The joint is connected by inserting the column connecting cylinder through the column. The beam and the column are connected by inserting the tip of the beam into the horizontal connection cylinder of the joint connected to the column. When inserting the tip of the beam into the horizontal connecting cylinder of the column, it is necessary to tilt the column to increase the distance between the columns. This is for putting the beam into the horizontal connecting cylinder of the joint fixed to the column. Pillars connected vertically to the base cannot be easily tilted. In particular, the pillar connecting the beams first is difficult to tilt. In addition, if the pillar is tilted, it may fall. For this reason, there is a drawback that the work cannot be performed safely. As described above, the joint connected to the column has a disadvantage that the beam cannot be easily connected. Further, in the case of a building on the second floor, connecting the beams by tilting the pillars on the second floor is a more dangerous work, and it is actually impossible to perform the construction at all.

Further, in a building using the joints shown in FIGS. 1 and 2, compared with a structure in which a horizontal structural member such as a base or a girder is connected with a cross-sectional defect, the strength of the connecting portion can be considerably increased. However, in order to improve the seismic resistance of a wooden building, a stronger structure is desired. In particular, a technology for improving the strength of a building by using wood having insufficient strength for columns, girders, and the like has been desired. Wood that does not have sufficient strength grows quickly. In other words,
Since it grows fast, the grain of the wood is coarse and not strong enough. Such timber is enormously produced nationwide. However, since it cannot be used as a structural material for buildings, it is not used effectively. If a technology that can effectively use such timber as a structural material for a building is developed, the unit price of the structural material used for the building can be reduced,
Significantly less imported wood from foreign countries. For this reason,
There is a strong need for a technology that can effectively use wood that is not effectively used.

[0007] The present invention has been developed for the purpose of further solving this drawback. It is an important object of the present invention to provide a building in which structural materials can be connected simply and easily and securely by a safe operation. Still another important timber of the present invention is to provide a building which can remarkably improve the strength as a building even if wood having insufficient strength is used.

The bracing 5 fixed to the joint 2 via the connecting piece 10 is connected to the upper and lower sides of the diagonally adjacent column 1A as shown in FIGS.

As described above, the structure in which the bracing is connected to the joint has a considerably greater resistance to tensile force than the conventional structure in which the bracing is connected by nails or bracing. When a strong tensile force acts on the braces connected by nails or braces, the nails or braces are deformed or the wood is broken at the portion where the braces or braces are driven, so it is difficult to firmly connect the braces. The joint provided with the connecting piece 10 at the connecting portion between the horizontal connecting tube 3B and the column 1A connecting portion 3E can firmly connect the bracing through a stopper such as a bolt. This is because the thick bolt penetrates the bracing 5 and the bolt is firmly connected to the connecting piece 10.

The connecting piece shown in these figures is formed integrally with the joint. The connecting piece is not shown, but can be welded to the joint by welding or the like, or fixed to the joint by bolting. You can also. Further, the connecting piece can be connected to one of the horizontal connecting tube and the column connecting tube.
Bracing is important for structural durability, but may not be installed in some locations. In such a case, there is a feature that the connecting piece that can be attached to the joint can be used by attaching it only to the place where the bracing is to be attached at a factory or a site.

[0053]

The building according to the present invention has the feature that the structural members such as columns and girders can be easily and easily connected firmly with a safe operation. This is because the building of the present invention is firmly connected via a joint without causing a column, a beam, a girder, or the like to have a cross-sectional defect at a connecting portion as in a conventional wooden building. In the building of the present invention, fittings for connecting structural members have fitting openings in one or both of the column connecting tube and the horizontal connecting tube. The connecting cylinder having the fitting opening can be constructed not by inserting the structural material to be connected in the axial direction but by fitting in a direction perpendicular to the axial direction to construct the wall. For this reason, in the building of the present invention, a structural material can be simply and easily inserted into the joint to construct a strong wall.

Further, in the building of the present invention, a stop hole is opened in the horizontal connecting cylinder and the column of the joint, and a structural member such as a horizontal structural member or a column is firmly connected by a stop member inserted therethrough. This structure can be firmly fixed with a stopper which penetrates a structural material such as a pillar or a horizontal structural material. The joint, which is more firmly fixed with the stopper, can firmly connect the connecting cylinder and the structural material, and can also increase the strength of the connecting portion, and at the same time, can realize a stronger structure of the structural material.

Further, the building of the present invention having a wall structure in which joints are connected diagonally by struts,
The feature is that the wall structure can be made extremely tough. The bracing is connected and fixed to a connecting piece provided in the joint. The wall structure in which the bracing is connected to the connecting piece of the joint can be synergistic with the fact that the structural material can be connected by the joint without losing the cross section, and the strength of the wall can be significantly increased.

In order to test how excellent the wall structure of the building of the present invention exhibits strength, a wall panel having a width of one space was prototyped and the strength was tested. The wall panel was fixed horizontally on the lower surface, and the upper end was pressed laterally by a hydraulic cylinder to perform a test of breaking the panel. As a result, the wall structure of the conventional wooden building was destroyed by pressing the wall panel with a pressing force of 1 ton or less. On the other hand, the wall structure of the building of the present invention did not break even when a pressing force of 5 tons was applied, and exhibited extremely tough strength incomparable with a conventional wooden building. The same structural material was used for the wall panels. As described above, the building of the present invention, which can have a tough wall structure using the same structural material, can significantly increase the strength of the building by using wood having insufficient strength for the structural material. For this reason, the building of the present invention has an extremely excellent feature that a tough building can be formed by using a square material that cannot be used effectively because of insufficient strength.
