Description

(4) The present invention relates to a building in which a pillar is connected to a foundation and a horizontal structural member such as a beam or a beam by a joint, and a joint for a building used for remodeling of a building already constructed.

Current wooden buildings connect columns, beams, etc. in a so-called "cut-type" structure. One of the cuts is provided with a connecting through-hole or a groove, and the other is provided with a protrusion inserted into the through-hole and connected. This connection structure requires a high level of specialized technology for the processing of the 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 beam is cut off and connected, that is, a structure in which a part of the structural material is cut off in section, significantly increases the strength of the connection part. It is a cause of lowering. This is because, when a certain load or more is applied to the connecting portion, the weak portion (cross-section defect portion) generated by the cut is broken, and the building starts to collapse. That is, this structure reduces the vibration resistance of the wooden building.

継 手 To prevent such adverse effects, architectural joints have been developed to connect columns and columns with horizontal structural members such as beams or beams (see Patent Documents 1 to 7).

Japanese Utility Model Publication No. 57-161609 JP-A-54-69712 Japanese Utility Model Publication No. 52-78303 JP-A-6-322838 Japanese Utility Model Publication No. 56-76806 Japanese Utility Model Publication No. 52-77505 JP-A-56-102304

継 手 The joints described in these publications can improve the earthquake resistance by increasing the connection strength between columns and beams. However, since the joints described in these publications are designed to be used in a process of connecting a column to a base or a beam, they cannot be mounted on a column connected to a base or a beam, Alternatively, a structure that can be connected in this state has a disadvantage that it cannot be connected firmly. Therefore, it is not possible to retrofit existing buildings to significantly improve their seismic strength.

The present inventor has actually developed a joint that fits and connects columns, foundations and beams, and has actually built many buildings. In a building of this structure, when a load exceeding the seismic isolation force is applied to the connection between the column and the base or the beam, the force toward the collapse can be dispersed and protected by the joint, so that the collapse of the building can be effectively prevented. By the way, the building of this structure was proved to have about 4.8 times the strength of the conventional construction method in the experiment of the third party organization. Buildings with this structure have the feature that the connection strength between columns and foundations or beams can be significantly improved. However, the so-called “pre-construction” process of connecting the pillars to the bases and beams to construct the skeleton of the building took much time and effort compared to the conventional method using no joint. The timing for fitting the joint to the column or base, etc. is specified.If this timing is incorrect, the joint cannot be installed.In addition, the joint fitted to the column, etc. is placed at a specific position while the column is This is because it is connected to the beam. Further, in the structure in which the columns are connected while being positioned by the joint, it is necessary to precisely adjust the position where the joint is fixed, which also requires time and effort before construction.

The fire 17 is connected, for example, to the side wall 31 of the horizontal structural member connecting portion 3b of the intermediate joint 3B. It should be noted that, although not shown, the firing may be a metal hardware firing. The metal fire is provided with a connecting piece connected to an intermediate joint at both ends, and a connecting bolt is inserted into a connecting hole opened in the connecting piece to be connected to a base or a beam via the intermediate joint.
