Instead of the drift pin, a fastener consisting of a bolt and a nut, or a coach screw (lag screw) C as shown in FIG. 5C may be used. According to the connector of the first embodiment and the connector of the second embodiment described above, the connecting plate portions 37, 39, 46, 48, 50 for fixing and mounting the beam are vertically divided into two or three. The connecting plate has a structure in which the connecting plate part is divided and separated from each other, and the connecting plate part for fixing and attaching the beam is connected to the pillar, as compared with the connecting plate part extending from the entire longitudinal direction of the plate surface. Part 3
The weight of the plate material of 7, 39, 46, 48, 50 can be reduced,
Since the weight of the joint device as a whole can be reduced and the material cost can be reduced, it is advantageous in terms of cost.

Further, since the weight is light, the handling is easy, and the work of connecting the building members becomes easy. Here, noteworthy features of the connector of each of the above-described embodiments will be described. As a construction method using a conventional building member joint device, a method of connecting a plurality of pillars with a connector without connecting through pillars, connecting another connector to this connecting portion, and connecting a beam or the like to the connector However, there are various connectors, and there are problems in manufacturability and assembly.

Therefore, the present inventor has proposed to use only one type of connector, and therefore to use through columns. That is, a method has been proposed in which a connector is connected to a through column and a beam or the like is connected to this connector.

In this case, if the connector is simply connected to the through-column by bolts as in the conventional case, the shearing force generated at the joint between the through-column and the connector cannot be resisted only by the proof stress of the bolt, and a strong connection is achieved. No strength can be obtained.

Therefore, the present inventor further provides a shear connector and a shear ring as shown in the embodiment on the connector, and inserts these into a column, whereby the shearing force generated at the joint between the column and the connector. It was designed to resist and to obtain a strong bond strength.

By devising the connector having the above structure, the connector can be unified and used as a single type, the production of the connector is not troublesome, the management is easy, and the great labor saving and the cost reduction can be realized. It is possible to reduce the number of parts to be processed into building members and to eliminate the need for skilled engineers, thus shortening the construction period.

By using such a connector, the joining of the building members can be completed by a simple operation of simply using a fastener such as a drift pin. Further, since the connector and the building member connected thereto can be standardized, it is sufficient to prepare all the connectors at the factory and pre-cut only the building members to be used at the factory. Furthermore,
The connection of building members using a connector is extremely strong, and the strength is overwhelmingly large as compared with the conventionally known method using a simple iron plate or bolts and nuts.

Further, the strength and accuracy of the structure depend on the skill and skill of the carpenter who works, but by using the connector 1 described above, any person can carry out the work regardless of skill and skill. A certain uniform strength and accuracy can be expected.

In particular, in the conventional shaft construction method using the connector having the above-mentioned unique construction, when the building members are connected to each other, the joints and joint members which have been conventionally provided in the building members are described above. It can be replaced with a connector, and in the case of a pillar, only the processing for providing a bolt insertion hole is performed, so it does not require a high degree of skill and skill such as coupling of building members, and can improve work efficiency and building members. It excels in economy and strength of the connecting part, and the cost can be reduced by shortening the construction period.

Further, in the above-mentioned method of constructing a building proposed by the applicant of the present invention, a plurality of pillars are connected by the connector as described above. Since use is a condition, the work of connecting building members is easy and the construction period can be shortened.

In addition, in each connector, for the first connection
Nail insertion holes X and Y may be formed in the plate portion and the receiving plate portion . In this case, before fastening the first connecting plate portion to the pillar,
The first connecting plate portion is temporarily fixed to the pillar with a nail inserted through the insertion hole X, and the positioning is adjusted and fixed.

Before fastening the beam to the second connecting plate portion with the drift pin, the beam is positioned and fixed to the receiving plate portion with the nail inserted in the insertion hole Y.

[0053]

As described above, according to the joint device for building members of the invention according to claim 1 or 2 , it is possible to reduce the weight of the plate material of the connecting plate portion for fixedly mounting the beam or the like, and the joint. Since the weight of the entire apparatus can be reduced and the material cost can be reduced, it is advantageous in terms of cost, and as a result of the light weight, it is easy to handle and the work of connecting the building members becomes simple.

[0054]

According to the inventions of claims 3 to 5 , the first
The shearing force generated at the joint between the connecting plate portion and the building member such as the pillar can be resisted together with the proof stress of the fastener, and the joint strength can be improved.
