Referring to fig. 1-3, an embodiment of the present utility model provides a prefabricated component template reinforcing tool, which includes a nut 1, the nut includes a main body 2, a connecting hole 3 is configured in the main body 2, and a convex structure 4 is configured in the connecting hole 3 so as to be connected with a fast wire; the end of the main body remote from the connecting hole 3 is connected with a reinforcing structure. As an example, the convex structures 4 may be a plurality of projections arranged at intervals along the inner wall of the connection hole 3 in the depth direction of the connection hole 3. In some embodiments, the inner wall of the connecting hole 3 is substantially square, and four corners of the square form smooth transition. The protruding blocks can be arranged on four surfaces of the square inner wall at intervals. Compared with a fine internal thread, the convex structure 4 has low requirements on the precision of mechanical connection, so that even if some tiny dust, concrete and the like enter the connecting hole 3 in the assembly process, the stability of the connection is not obviously affected, and the fault tolerance of the connection is improved. In addition, the end of the main body 2 far away from the connecting hole 3 is connected with a reinforcing structure, and the reinforcing structure is usually positioned in the inner page or the outer page of the prefabricated part, so that the effect of improving the stability of the reinforcing connection can be achieved. The outer surface of the body 2 may be subjected to compression molding treatment to form the bump on the inner wall of the connection hole 3 when the bump is formed, so that it can be seen from fig. 1-2 that the outer surface of the body 2 has a recess 21, and accordingly, in the perspective structure of fig. 3, it can be seen that the convex structure 4 is formed on the inner wall of the connection hole.

In some embodiments, the reinforcing structure is a horizontally disposed reinforcing bar, which may increase the strength of the connection in the horizontal direction.

One ends of the two reinforcing ribs are connected into a whole through an arc-shaped part 7, the first reinforcing rib 5 positioned at the upper part penetrates through the main body and is fixed with the main body 2 (such as by welding and the like), and the second reinforcing rib 6 positioned at the lower part penetrates through the lower part of the main body 2. Therefore, only one fixing point between the first reinforcing rib 5 and the main body 2 is needed, the first reinforcing rib 5 and the second reinforcing rib 6 can be fixed on the main body 2, the connection points between the reinforcing ribs and the main body 2 are reduced, and the connection cost is saved.

Optionally, the length of the reinforcing rib on one side of the main body is longer than that on the other side of the main body, for example, the length of the reinforcing rib on the side where the arc-shaped part 7 is located is shorter, the other side is longer, so that the shorter side is close to the edge of the prefabricated part 8, the longer side extends towards the middle of the prefabricated part, the nut 1 is closer to the edge of the prefabricated part 8 while the reinforcing effect of the reinforcing rib is ensured, and therefore, when the template is connected with the edge of the prefabricated part 8, only a small part of the edge of the template needs to be lapped on the edge of the prefabricated part 8 to be aligned with the position of the nut 1, thereby realizing reinforcing connection, which is equivalent to reducing the width requirement on the template and reducing the weight of the template.

Optionally, the main body 2 includes a first main body 201 and a second main body 202 connected to the end of the first main body 201; the connection hole 3 is constructed inside the first body 201; the second body is in a vertically arranged plate shape. In this embodiment, the first body 201 has a substantially square tubular structure. The second body 202 is substantially vertically arranged plate-like, and a transition section from the first body 201 to the second body 202 is in a slope structure to realize smooth transition, so that stress between the first body 201 and the second body 202 can be more uniform and smooth in transition. The second body 202 is substantially vertically arranged in a plate shape, and when the reinforcing tool is connected with the assembled side mold (as described below), the vertically arranged plate structure can have a larger contact surface with the inner side of the side mold, and can play a certain role in supporting and stabilizing each component part of the side mold, thereby being beneficial to improving the firmness of the assembled side mold.
