Description

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.

[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 connecting columns, connecting beams, connecting columns and beams, and so on. And the 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.

The connector shown in FIG. 4 is used for a column head, and the beam 8 is coupled to the head of the column 6. The structure is such that two second applied joint members 3 are assembled to a basic joint member 2 having the same structure as the connector 1 of FIG.

Further, the connector shown in FIG.
The column 13 is connected to the foundation 20 and the beam 8 is connected to the column 13.
The structure is as follows. That is, the basic joint member 2 of this connector has one end plate portion 2a and a first and second end plate portion 2a that form a space into which the pillar 13 as the first vertical building member whose material axis extends in the vertical direction is fitted. Two side plate portions 2b and 2c
And has a substantially U-shaped vertical cross-sectional shape, and is used so that the end plate portion 2a is located in the lower portion.

The first and second side plate portions 2b and 2c of the basic joint member 2 have the same first structure as the connector 1 of FIG.
The first connecting plate portion 3A of the applied joint member 3 and the first receiving plate portion 15 are fixed to each other by welding. In the case of this connector 1, a bolt insertion hole is formed in the first receiving plate portion 15, and, for example, an anchor bolt protruding from the upper surface of the base portion 20 is inserted into this bolt insertion hole, and this anchor bolt is inserted. A nut is fitted to the bolt portion at the tip to fix the connector to the base portion 20.

According to the connector described above, the joining of the building members can be completed only by a simple operation of using fastening means such as bolt fastening. The floor area and height can also be freely changed with a very small amount of fixed-size products.
