Description

  The present invention relates to a construction joint metal fitting, and in particular, to a construction joint metal joint that can improve the joining strength with a simple structure in which one wood member is obliquely joined to the other wood member.

Conventionally, as a method of joining a wooden member for construction that joins a cross member such as a beam and a vertical member such as a column, a method of applying mortise processing or unpiercing processing to wood and combining these pieces of wood has been used. .
In recent years, when a cross member and a vertical member are joined using a construction fitting, it can be firmly joined by joining wood together, and the work efficiency at the construction site can be improved. Various types of construction joint fittings have been proposed.

For example, Patent Document 1 is fitted into an engaging groove provided on a joining surface of a joining member (the other wood member) that is obliquely coupled with the end face contacting the main trunk member (one wood member). The technique of the connection tool of the wooden building member which consists of a connection piece and the protrusion which protrudes from the edge part of a connection piece in the state fitted in the fitting hole provided in the joint surface of the main trunk member is disclosed.
According to this technique, since two pieces of wood are connected obliquely, the processing applied to the connecting portion of the wood can be easily performed, and the strength of the wood can be maintained in a good state even after the processing.
JP-A-11-172788

  However, the connector disclosed in Patent Document 1 needs to be processed obliquely so that the joint surface of the joint member (the other wooden member) comes into contact with the side surface of the main trunk member (the one wooden member). There was a problem that the processing cost could not be reduced. Further, excessive stress concentration occurs at the connection portion between the protrusion and the connection piece, and there is a concern that sufficient mechanical strength cannot be maintained. Furthermore, there is a problem that the structure is complicated and the manufacturing cost cannot be reduced.

  In order to solve the above problems, an object of the present invention is to provide a joint fitting for construction that can improve the joining strength with a simple structure in which one wooden member is obliquely joined to one wooden member. To do.

In order to achieve this object, a construction joint metal fitting of the present invention is a construction joint metal fitting for obliquely joining one wood member to the other wood member, and is fixed to the one wood member. And a connecting member attached to the other wooden member and connected to the receiving member, and a bolt for fixing to the one wooden member passes through a side surface of the receiving member. A penetrating portion is formed, and one or more engaging grooves are formed at a position corresponding to a joining angle between the one wooden member and the other wooden member, and the engaging member is formed at one end of the connecting member. It is set as the structure which formed the to-be-engaged part engaged in an insertion groove.
If it does in this way, while the other wooden member (for example, purlin) can be diagonally joined to one wooden member (for example, corner tree), joint strength can be improved. Moreover, the end surface of the other wooden member can be easily processed, and the processing cost can be reduced.

Further, the architectural fitting of the present invention has a configuration in which the receiving fitting is cylindrical.
In this way, the structure of the receiving metal fitting can be simplified, it is possible to easily cope with an arbitrary joining angle, and the manufacturing cost can be reduced.

Further, in the architectural fitting of the present invention, the penetrating portion is composed of a cylindrical member.
In this way, even if a large external force is applied to the metal fitting, an external force is applied to one of the wooden members via the cylindrical member, so that the amount of biting of the bolt with respect to the one wooden member is reduced, and the cylinder is easily formed. The member can be fitted into the wooden member, and the receiving metal fitting can be accurately positioned.

Moreover, the building joint fitting of the present invention is configured such that the penetrating portion is provided at two or more locations in contact with the one wooden member, and one of them is a cylindrical member.
If it does in this way, since a receiving metal fitting can be firmly fixed to one wooden member, joint strength can be raised further.

Further, in the architectural fitting of the present invention, the connecting member is a rod-shaped or cylindrical member, and a locking bolt to be engaged with the engaging groove of the receiving metal is fastened to one end face of the member. The inserted engagement portion is provided, and an attachment hole for attaching a fixture to the other wooden member is formed in the other end portion in a direction perpendicular to the shaft center.
If it does in this way, the other wooden member can be rotated by making the locking bolt engaged in the engagement groove | channel of a metal fitting into a rotating shaft. Therefore, for example, when the other wooden member is a purlin, the purlin can be rotated. Therefore, the purlin and the rafter can be joined in a surface-bonded state, and the joining strength can be improved.

Further, in the architectural fitting according to the present invention, the connecting member is a plate-like member, and the engaged member is formed with a groove to be engaged with the engaging groove of the receiving member at a lower portion on one side of the member. An attachment portion is provided, and an attachment hole for attaching a fixture to the other wood member is formed in the member.
If it does in this way, while being able to simplify the structure of a connection member, connection work can be performed easily.

Further, the architectural fitting of the present invention has a configuration in which a fixing bolt hole through which the fixing bolt penetrates is formed below the engaging groove of the receiving metal fitting.
If it does in this way, since the other wooden member can be firmly fixed to a receiving metal fitting, joint strength can be raised.

  According to the architectural fitting in the present invention, one wooden member (for example, a corner tree) can be obliquely joined to the other wooden member (for example, a purlin), and the joint strength can be improved. In addition, the end surface of the other wooden member can be easily processed, and the processing cost can be reduced.
