Therefore, unlike the related art, there is no need to provide a claw or a shear ring having a function of resisting the shearing force generated at the joint, and the configuration can be simplified. Further, the connector having such a configuration does not require a step of joining the plates by welding or the like in the manufacturing process, and has an advantage that it is excellent in manufacturability and advantageous in cost.

In the present embodiment, the basic joint member 10, the second and third applied joint members 12, 13 extend from the lower edge of the vertical plate portion in a plane substantially perpendicular to the vertical plate portion, Since the receiving plate portions 43, 44, and 45 are fixed to the lower ends of the vertical plate portions, the receiving plate portions 43, 44, and 45 can receive horizontal building members such as beams. Since the positioning can be easily performed, there is an advantage that the fastening operation is easy.

Here, the drift pin corresponds to FIG.
(A) It is configured as A, and a portion thereof is formed by embossing a groove in a mesh shape so as to have resistance.
Also, two blades b are fixed to the base end of the drift pin B shown in FIG. 17B, and the blade b bites into the wooden part, and after the pin B is driven, the pin B To prevent them from returning. In addition, this drift pin B
Was previously filed by the applicant.

In place of the drift pin, a fastener consisting of a bolt and a nut, or a coach screw (lag screw) C as shown in FIG. 17C may be used. Here, the connector of the present invention has the basic joint members 10 and 3.
By combining the first to third applied joint members 11 to 13 with respect to 5, other types of connectors can be configured,
The production of the connector does not take much time, the management is easy, the labor saving and the cost reduction become possible, the processing part to the building member can be reduced, and the necessity of the skilled technician can be eliminated. The construction period can be shortened.

By using such a connector, the connection of the building members can be completed only by a simple operation of using a fastener such as a mere drift pin. Further, since the connectors and the building members connected thereby can be standardized, all the connectors may be prepared at the factory, and only the building members to be used may be precut at the factory. Furthermore,
The connection of the building members using the connector is extremely strong, and the strength is overwhelmingly large as compared with a conventionally known method using a simple iron plate, bolts and nuts.

The rigidity and precision of the structure depend on the skill and skill of the carpenter who performs the work. However, the use of the above-described connector 1 allows any person to work regardless of the skill and skill. A certain uniform strength and accuracy can be expected.

In particular, in the construction method of the conventional framing method using the above-described connector having a unique configuration, when connecting the building members, the joints and joint members conventionally provided on the building members are replaced with the above-described connection members. It can be replaced with a connector, and in the case of pillars, only the process of providing bolt insertion holes is required. Therefore, there is no need for a high level of skill and skill such as connection of building members. It is excellent in economy, strength of the joint, etc., and can reduce costs by shortening the construction period.

In each connector, the locking plate 15,
It is preferable to form a screw insertion hole X in 37. in this case,
In a state where the locking plates 15 and 37 are in contact with the head of the column, the locking plates 15 and 37 can be positioned by being fixed to the column with screws inserted into the insertion holes X.
