れている。(Prior Art) When constructing various buildings using concrete, an embedding device called an insert is used as a means for embedding a nut body for screwing a hanging bolt in advance in a concrete wall surface. Usually, this embedded tool has a nail protruding from the opening side of the nut body.
This nail part is driven into the concrete pouring side of the formwork and fixed in a predetermined position of the formwork, and then concrete is poured in. Then, the formwork is dismantled and removed, thereby embedding the embedded tool in the concrete wall surface. However, after the formwork is dismantled, the nails protrude from the concrete wall surface, resulting in the inconvenience that the nails must be cut and removed. In order to improve this inconvenience,
As seen in Publication No. 44171, the embedded tool is composed of two elements: a main body with a nut body inside and a mounting plate equipped with nails, and the mounting plate is separably fitted into a recess in the main body. An embedded device has been proposed in which, when the formwork is dismantled, the mounting plate separates from the main body buried in the concrete wall surface and is removed while being nailed to the formwork side.

の時間と労力を要している。(Problem that the invention aims to solve) However, in the case of embedded fixtures that combine a main body with a nut body and a mounting plate equipped with nails, when the formwork is dismantled, the nails protrude from the surface of the concrete wall. This method has the advantage that no nails remain, so there is no need to cut and remove the nails. However, on the other hand, the mounting plate remains nailed to the formwork side, and the removal work of this mounting plate is extremely time consuming. It is difficult and requires a lot of time and effort to remove the mounting plate.

共に容易に取り除くことができる。(Function) When the mounting plate 5 equipped with nails 4, 4 is fitted into the recess 3 of the main body 2 in which the nut body 1 is installed, the nails 4, 4 are inserted into the predetermined positions of the formwork 8 by a conventional method. The embedding tool 10 is fixed to the formwork 8 by pouring the embedding tool 10 into the formwork 8, then concrete is poured between the formworks to bury the embedding tool 10 in the concrete, and then the formwork 8 is dismantled and removed, as shown in Fig. 6. The main body 2 is held within the concrete wall 7, and the mounting plate 5 is detached from the main body 2 and remains on the formwork 8 side. Therefore, the space 6 of the mounting plate 5
By inserting the tip of a tool such as a crowbar and performing a pulling operation, the mounting plate 5 together with the nails can be easily removed from the formwork 8.

止することができる。 As described above, the main body 2 is equipped with the embedding tool 10 and the nut body 1, and the mounting plate 5 is equipped with a nail.
In a structure in which the mounting plate 5 is fitted into a recess 3 provided on the main body 2 side, the mounting plate 5 is tightly fitted into the recess 3 so that it cannot easily slip out. need to be mated,
For this reason, a press-fitting method is usually employed, but this press-fitting method has the disadvantage that the peripheral wall of the recess 3 of the main body 2 often breaks. In order to eliminate this inconvenience, it is desirable to provide slits 12, 12 in advance on both sides of the peripheral wall of the recess 3 of the main body 2, as shown in FIGS. If the outer circumferential dimension of the mounting plate 5 is formed slightly larger than the inner circumferential dimension of the recess 3 and the mounting plate 5 is press-fitted, the mounting plate 5
is accurately held within the recess 3, thereby preventing the production of defective products.
