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 & 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.

Here, as a representative example, the connection form of the connector 1A of FIG. 1 will be described, and the connection form of the other connectors 1B and 1C is basically the same as that of the connector 1A, and therefore omitted.

FIG. 4 shows a column 10 as a vertical building member using a connector 1A in which one first applied joint member 3 and one second applied joint member 4 are attached to the basic joint member 2. An example in which a horizontal member 11 as a horizontal building member and a diagonal member 12 as an oblique building member are connected to a foundation 13 is shown. That is, the anchor bolt 14 embedded in the foundation 13 of the building structure is inserted into the insertion hole 6 (not shown) formed in the end plate portion 2d constituting the basic joint member 2 to remove the anchor bolt 14 from the end plate portion 2d. Washer and nut 15 on the bolt protrusion
By fitting (hereinafter, abbreviated as a nut), the connector 1A is firmly fixed to the foundation 13. This nut 15

Here, if the relief 11c of the receiving plate portion 3b of the first applied joint member 3 is formed on the lower surface of the horizontal member 11 in advance, the lower surface of the horizontal member 11 is arranged on the same plane as the foundation 13. Therefore, for example, the foundation 1 is attached to the lower part of the horizontal member 11.
When there is 3, it is possible to prevent the horizontal member 11 from bending and the like.

On the other hand, since the horizontal member 11 and the diagonal member 12 to be joined to the second applied joint member 4 are the same as the method of joining to the first applied joint member 3, the description thereof will be omitted. Although the bolt and the nut are used as an example of the fastening means in the embodiment of the present invention described above, the fastening means is not limited to this fastening means, and for example, a drift pin (see FIG. 5).
Fastening means such as (a) and (b)) or a lag screw (Fig. 5 (c)) may be used. However, the fastening means shown in FIG. 5 cannot be used at all places where the fastening means of the present embodiment is required, and for example, the horizontal member 1 in FIG.
It can be used only when there is no risk that the building member will come off from the connector even if a load is applied to the building member in any direction, as in the case of connecting 1 and the diagonal member 12.

Here, the drift pin in FIG. 5 (b) is currently being applied for a patent by the applicant of the present invention. According to the connectors 1A to 1C described above, the coupling of the horizontal member and the diagonal member to the pillar as the building member can be completed by only a simple work of using fastening means such as bolting. The floor area and height can also be freely changed with a very small amount of fixed-size products. Even after the completion of construction, if expansion and remodeling are planned in advance, and if jointing equipment for it is used, the remodeling will be extremely easy It is easy and various kinds of houses can be constructed one after another according to the demands of the consumer by using a small number of standard products, as if combining block toys of various shapes. Further, since the joint device and the building members connected thereby can be standardized, all the joint devices need to be prepared at the factory, and only the building members to be used are precut at the factory. Further, the joining of building members using the joint device is extremely strong, and is overwhelmingly strong as compared with a conventionally known method using simple iron plates or bolts and nuts.

Notable features of the joint device are as follows. That is, instead of the conventional cubic or rectangular parallelepiped joint body, a simple H-shaped cross-section joint member is used as a basic member, so that the weight and material of the joint device can be reduced, and the cost can be reduced. As a result of its light weight, it is easy to handle and the work of joining building members is easy.

Further, in manufacturing the joint, the number of man-hours such as the number of welding points is small and the manufacturability is excellent.
