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 & beam method, and is a frame method mainly composed of columns and horizontal members.

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 assembled with a frame material, and a wall is formed with nails and hardware to construct 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.

[0005]

By the way, conventionally, in the construction of buildings such as wooden houses, after constructing a foundation,
Building members such as wood are skillfully cut and cut, and these are skillfully assembled and connected in accordance with structural mechanics. In particular, important connection parts of the building members are fixed with bolts or the like. However, such an ancient method requires a high degree of skill and skill such as connection of building members, is inferior in work efficiency, economical efficiency of building members, strength of connecting parts, etc., and requires a long construction period and eventually becomes expensive.

[0006] On the other hand, prefabricated buildings in recent years have solved some of the above-mentioned problems of economy by mass production, but they are inferior in durability and strength (particularly joints), lack versatility, and have a short period of use after construction. 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 for building members that is superior in strength to the traditional wooden incision method.

[0007] This is disclosed in JP-A-51-107626. That is, this joint is obtained by welding and fixing a plate-like member extending outward from a surface of the basic joint main body to a plane substantially perpendicular to the surface to a cubic or rectangular parallelepiped basic joint main body. The member is provided with a hole through which a fixture such as a bolt can be inserted. Many types of joint members can be obtained by changing the shape, number and direction of the basic joint member main body and the plate-like member and combining them.

However, such a conventional joint has the following problems. That is, as a result of applying the above-described basic joint body having a cubic or rectangular parallelepiped shape, the weight of the joint is considerably increased, the material cost is increased, and the cost is disadvantageous. Also, as a result of heavy weight,
Difficult to handle and difficult to connect building components. In addition, it takes a lot of man-hours to manufacture joints, such as many welds.
It is inferior in manufacturability.

Further, in the conventional joint, it is necessary to use different types of joints for joining columns, joining columns, joining columns and columns, and the like. It takes time and effort to manufacture, and its management 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. It is an object of the present invention to provide a joint device for a building member, comprising: a joint device for constructing a framework suitable for a building or the like in which both features of a conventional frame construction method and a frame wall method are mixed.

[0010]

Therefore, the invention according to claim 1 is used with the fastening means shown in the following A, and the first and the first shown in C and D are added to the basic joint member shown in B.
