DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint device for a building member for constructing a frame suitable for building a wooden house or a steel structure building.

[0002]

2. Description of the Related Art As a conventional method of building a building, there are well known a frame construction method and a frame construction method. The former is also called a skeleton skin method or a post and beam method, and is a frame method mainly composed of columns and beams.

The latter is also called a two-by-four construction method or a platform frame construction method, and is a floor formed by hitting a plywood for a structure or a face material having performance equal to or higher than that to a framework of a floor made of joists. In addition, a wall is formed by hitting a structural plywood or the like to a frame of a wall made of a frame material, and a wall is formed with nails and hardware to build a building.

[0004] The main difference between these construction methods will be described in comparison. First, the space configuration is the "axis (line)" for the former and the "plate (plane)" for the latter. The rigidity imparting structure such as floor and wall
The former is “blow-off, bracing”, and the latter is “structural plywood”. For the wood used, the former is "including large-sized and long materials (through pillars) mainly composed of squares", and the latter is "mainly composed of small-sized and short materials". For the construction process, the former is “first floor / second floor axis, hut continuous construction, floor”, the latter is “first floor → first floor → second floor → second floor wall → shed (step work)”
It is.

Conventionally, in the construction of a building such as a wooden house, after constructing a foundation, architectural members such as wood are skillfully cut and notched, and these are skillfully assembled and connected in accordance with structural mechanics. Particularly, important connection parts of the building members are fixed with bolts or the like. However, such an old method requires a high degree of skill and skill such as connection of building members, and is inferior in work efficiency, economy of building members, strength of connection parts, etc., and requires a long construction period and is eventually expensive.

[0006] On the other hand, prefabricated buildings in recent years have solved some of the above-mentioned problems of economy by mass production. It becomes poor with the passage of time, and when it is used for a long period of time, it is not possible to bring out the calmness and weightiness of the building. Therefore, the applicant of the present application has conducted intensive studies on the joining of the structural members as described above, and as a result, compared with the conventional simplest joining method, for example, a method of variously combining an iron plate, a bolt and a nut, it is further simpler. We have developed a joint device for building components that is superior in strength to the traditional wooden incision method.

This is disclosed in Japanese Patent Publication No. 6-57977. That is, this joint device allows a standardized pre-cut member to be used as a building member, and is a joint member device for a building member comprising a standardized joint member suitable for forming a frame of a building by combining the precut members. In addition, it is possible to construct a framework suitable for a building or the like in which both features of the conventional frame construction method and the frame wall construction method are mixed.

[0008]

However, in such a conventional joint device, a bolt and a bolt are all fitted as a fastening means for fastening each plate portion of the joint member to a column or a beam. Therefore, when fastening each plate portion of the joint member to a column or a beam, a large number of nut tightening operations are required, and there is a problem that workability is poor as a whole.

[0009] Further, since there are two parts, a bolt and a nut, there is a problem that the management of the parts becomes complicated. The present invention has been made in view of the above-described conventional problems, and enables a standardized precut member to be used as a building member, and a standardized joint member suitable for forming a framework of a building by combining the precut members. An object of the present invention is to improve workability, manageability of parts, and the like by improving a fastening means for fastening each plate portion of a joint member to a column or a beam.
