Claims

[Claims for Utility Model Registration] An end member is integrated at the end of each main structural member,
In a joining device equipped with a joining bolt that joins the main structural member to a node member having a threaded hole through the end member, the joining bolt is formed with a boss portion, and a boss portion is formed at both ends of the joining bolt. The threaded portions are formed with opposite threads to each other, a shaft portion having a larger diameter than the threaded portion is formed between the boss portion and the threaded portion on the base side of the connection bolt, and the inside of the end member has the A mounting hole having a diameter larger than the diameter of the anchor nut to be screwed into the threaded portion on the base side of the joint bolt is bored, and the inner surface of the support member that is inserted into the mounting hole and fixed to the end member has the following features: A female threaded portion is formed in the same helical direction and the same pitch as the threaded portion on the side opposite to the base of the connecting bolt, and a male threaded portion is formed on the shaft portion to be threaded into the female threaded portion, and is engaged with the outer surface of the boss portion. A sleeve body is provided that transmits rotation and allows the boss portion to slide in the axial direction, and a rotational force acting portion for rotating the boss portion is formed on the outer surface of the sleeve body. A structural member joining device characterized by:
