Claims

[Claims for Utility Model Registration] (1) A square steel pipe column, a joint box that is connected to the end of the square steel pipe column and forms part of the column, and a joint box that is connected to the side plate of the joint box. A column and a beam that are equipped with an I-shaped steel beam, and a mounting plate attached to the end of the I-shaped steel beam is brought into contact with the side plate of the joint box to connect the joint box and the beam with bolts. In the joint structure, the joint box is formed into a rectangular tube shape by three or more side plates, and the side plates and the mounting plate have a plurality of insertion holes for inserting bolts into each other. A nut holder is provided at a corresponding position and is attached to the inner surface of the side plate by an attachment means for holding a nut to be screwed into the bolt, and the nut holder is provided with a nut holder for holding a nut. A storage recess is formed to prevent the nut from rotating, and the I-shaped steel beam and the joint box are arranged so that the nut can be inserted through these insertion holes with the insertion hole of the mounting plate and the insertion hole of the side plate aligned. A joint structure between a column and a beam, characterized in that the column and beam are joined by screwing a bolt into a nut held in a holder. (2) The column-to-beam joint structure according to claim 1, wherein the attachment means is a screw. (3) It is equipped with a square steel pipe column, a joint box that is connected to the end of the square steel pipe column and forms part of the column, and an I-beam steel beam that is connected to the side plate of the joint box. , in a column-to-beam joint structure in which a mounting plate attached to the end of an I-shaped steel beam is brought into contact with a side plate of a joint box, and the joint box and the beam are joined with bolts, The Intobox is formed into a rectangular tube shape with three or more side plates, and the side plates and the mounting plate are provided with a plurality of insertion holes for inserting bolts vertically and in corresponding positions. A rib is formed on the inner surface of the side plate and between the upper and lower insertion holes of the side plate, and projects horizontally and inward, and the rib is screwed with the bolt. A nut holder is attached to hold the nut, and the nut holder has a fitting recess that is fitted onto the rib and formed of an elastic member, and a fitting recess that is formed above and below the fitting recess. and a storage recess formed at a position corresponding to the insertion hole of the side plate to accommodate the nut, and the I
The shaped steel beam and joint box are constructed by aligning the insertion holes of the mounting plate with the insertion holes of the side plate, and screwing bolts through these insertion holes into the nut held by the nut holder. A joint structure of columns and beams that is characterized by being joined.
