2. Description of the Related Art For example, in the construction of a steel building, end plates at the ends of an H-shaped steel beam having upper and lower flanges and a web connecting these flanges are bolted to the side surface of a square steel tubular column. In this case, the bolt holes formed in the end plate at the end of the steel beam and the bolt holes formed in the side surface of the square steel pipe column should be aligned when performing this bolt connection. At the construction site, it is necessary to support the steel beam and position the end plate at the end of the beam with respect to the side surface of the column. Conventionally, this positioning work requires a considerable amount of time. There was a problem that I could not go efficiently.

In view of the above-mentioned conventional problems, the present invention, when bolting a plate such as an end plate at the end of a steel beam to a side surface of a mating member such as a steel column,
The plate can be efficiently positioned to the predetermined position on the side surface of the mating material, and the plate and mating material can be bolted together efficiently. An object is to provide a positioning structure for bolt connection.

The above-mentioned problem is a positioning structure for bolt-bonding a plate to a mating material, which is formed when the plate along the side surface of the mating material is bolted to the mating material. Then, a receiving metal fitting is attached to the side surface of the mating member so as to project outward, and the lower end portion of the plate is received by the receiving metal fitting so that the plate is at a predetermined height position in the vertical direction with respect to the mating material. It is solved by a positioning structure for bolting a plate to a mating material, characterized in that it is positioned in the.

In this positioning structure, when the plate is bolted to the side surface of the mating member, the lower end of the plate is simply received by the metal object so that the plate is along the side surface of the mating member. The side surface of the mating member is positioned at a predetermined height position. After that, if necessary, the plate can be displaced laterally along the side surface of the mating member so that the bolt hole of the plate and the bolt hole of the mating member are aligned with each other. When it is necessary to displace the bolt holes in the lateral direction along the side surface of the mating material to align the bolt holes, for example, use a shino and insert this into the bolt holes of the plate and the mating material. With this, it is possible to easily perform the center alignment. In this way, when the plate is bolted to the side surface of the mating member, the plate can be efficiently brought into the predetermined positioning state with respect to the side surface of the mating member without taking time. The bolts can be joined efficiently.

In the above positioning structure, the receiving member includes a bolt and a sleeve material, and the sleeve material is clamped by a bolt between a nut or a bolt head screwed to the bolt and a mating material. It is also preferable that the sleeve member is mounted so as to project outward from the side surface portion of the mating member, and the lower end portion of the plate is received by the outer peripheral top surface portion of the sleeve member.

In this structure, the tightening amount of the bolts and nuts is automatically determined by the sandwiching of the sleeve material without being too shallow and not too deep. Therefore, the mounting of the receiving metal fitting to the mating material can be performed without welding and efficiently. I can go well. Of course, the amount of protrusion of the receiving metal fitting from the side surface of the mating member is not too large or too small, and the optimal amount of protrusion can be efficiently set.

In this positioning structure, the nut or the bolt head, or the component interposed between the nut or the bolt head and the sleeve member serves as a plate engaging portion and the plate. The plate may be engaged so as to restrict the plate from displacing in the direction away from the side surface of the mating member.

In this structure, the plate engaging portion prevents the plate from displacing in the direction away from the side surface of the mating member and coming off from the receiving metal fitting, and the plate can be stably received by the metal fitting.

When the mating member is a steel frame column and the plate is an end plate provided at the end of the steel beam, the beam is efficiently bolted to the column in the bolt connection of the column beam of the steel frame. be able to.
