る。2. Description of the Related Art In steel-framed buildings, bolts are often used for joining columns and beams or joining beams. Recently, even in detached houses and apartment houses, the number of two-story or three-story buildings has been increasing, and when building these buildings, the work of joining the columns and beams on the upper floor to each other is difficult. Work is relatively high. It is general that the joining work at such a part is performed by arranging workers on the upper floor and the lower floor, respectively, and sequentially proceeding by these workers. However, in the above work, the number of workers and the work time increase, etc.
There is a problem that the cost required for the work increases significantly.

の数を減らすことが出来る。For this reason, a main body 51 and a mandrel as shown in FIG.
Bonding is performed using a fastener consisting of 52. That is, the beams overlap the holes formed in the members to be joined such as columns, and after inserting the main body 51 into these holes, the mandrel 52 is driven into the holes 51a of the main body 51, and the end portions 51b of the main body 51
Are joined by letting them open. When this fastener is used, the joining operation can be performed from one direction, and the number of workers can be reduced.

In this case, the bolts can be inserted into holes formed in the columns and beams, and the nuts can be fastened to attach the bolts. However, in such a mounting method, when the nut is fastened again after the other members are joined, the bolt may rotate together. For this reason, bolts or nuts are attached to beams or columns by arc welding, stud welding, or the like.

However, when this work is performed, an extremely narrow space surrounded by floors and walls is required. It is necessary to perform an operation of inserting a bolt into a vehicle, and this operation is not easy, and in many cases, the floor or wall must be largely broken. For this reason, there is a problem that a large amount of cost and construction time are required for the extension.

徴とするものである。In order to solve the above-mentioned problems, a bolt mounting structure according to the present invention is a bolt mounting structure in which bolts are mounted in advance in bolt holes formed in predetermined members. A bolt is inserted through the bolt hole and a mounting member is inserted through the bolt, and a mounting piece having a spring property formed on the mounting member is brought into contact with a screw thread of the bolt to attach the bolt to the predetermined member. It is characterized by putting.

取り付けることが出来る。In the above-described bolt mounting structure, the bolt is inserted into a bolt hole formed in a member to which the bolt is to be mounted, and the mounting member is inserted through the bolt, so that the mounting piece having spring properties provided on the mounting member is provided. The bolt enters the valley, and the vicinity of the tip of the mounting piece comes into contact with the thread in the direction in which the mounting member is inserted, and the tip contacts the thread or valley in the direction that has already passed. As a result, the bolt is prevented from coming off from the inserted bolt hole, and maintains the state of being attached to the target member. That is, bolts can be attached.

がない。When the nut is tightened in a state where the mounting piece of the mounting member is in contact with the screw thread of the bolt, the mounting piece is located near the surface of the target member and near the surface. It enters between the threads on the outside. At this time, the vicinity of the tip of the mounting piece comes into contact with the screw thread on the surface side of the target member, and the tip touches the side face or the valley of the screw thread separated from the surface of the target member. For this reason, the bolt is urged in a direction separating the thread from the target member in accordance with the spring reaction force of the mounting piece, and the head of the bolt is pressed against the surface of the member.
Therefore, when screwing and fastening a nut to the bolt,
There is no so-called co-rotation in which the bolt rotates with the nut.

せることで、取り扱いを容易とすることが出来る。When the mounting piece formed on the mounting member gets over the screw thread, the mounting piece bends near the base. For this reason, when tightening the nut, it is necessary to form a deformation space between the female screw portion formed on the nut and the base of the mounting piece, in which the mounting piece can be deformed. In order to form a deformation space that can guarantee the bending of the mounting piece, chamfering corresponding to the deformation space is performed on the end of the female screw portion formed in the nut, or the deformation space is formed between the mounting member and the nut. A washer that can be formed may be interposed, or a disc spring that can form the deformation space may be interposed between the mounting member and the nut. In particular, by integrating the washer or the disc spring and the nut, handling can be facilitated.

り、共回りを防止することが出来る。In the above-mentioned mounting member, a plurality of mounting pieces are formed on the inner peripheral side of the thin plate, and since the mounting pieces have a predetermined width and a length enough to come into contact with the valleys of the bolts, the mounting member has The piece can enter between the screw threads of the bolt, thereby preventing the bolt from separating from the bolt hole and exerting a spring reaction force by contacting the side surface of the screw thread. Therefore, the bolt can be urged in the direction in which the head contacts the surface of the member by the spring reaction force of the mounting piece, and co-rotation can be prevented.
