面倒であつた。 Conventionally, in order to bury various types of wiring boxes such as outlet boxes, outlet boxes, and switch boxes in concrete structures, the opening of the wiring box is brought into contact with the inside surface of the temporary frame panel, and the outside of the temporary frame panel is placed in contact with the inside surface of the temporary frame panel. The mounting bolts inserted from the side are connected to the inside of the bottom side wall of the wiring box using a connector, and the nuts screwed into the mounting bolts are pressed against the outside surface of the temporary frame panel, and the wiring box is temporarily attached. It is temporarily fixed by pulling it strongly against the inside surface of the frame panel. For example,
Publication of Utility Model Publication No. 45-18990, Publication of Utility Model Publication No. 51-46335, etc. However, according to these publications, in order to attach the connector to the wiring box in advance, the claw pieces are bent or screwed. This required a lot of work, and it was a hassle to use tools such as screwdrivers and pliers from inside and outside the wiring box. Apart from this, in order to screw the mounting bolts directly into the bottom wall of the wiring box, there are also ones in which tapped holes are formed by burring the bottom wall using plastic processing, or female screw parts are pre-prepared on the bottom wall. Products that have been crimped and molded have been proposed and sold. According to these methods, even if it is not necessary to install the connector, it is not only expensive because it has been specially processed, but also requires concrete material to be removed from the tap hole or caulking member if it is buried without being temporarily fixed to the temporary frame panel. They either use special blocking procedures or use another type of wiring box to allow for entry. Therefore, two types of wiring boxes had to be prepared, and as a result, on-site use, storage, and inventory management required double effort and was extremely troublesome.

A connecting cylinder 9 that fits inside the mounting cylinder 3 is integrally formed, and a female thread 10 is formed on the inner circumferential surface of the connecting cylinder 9.
A protrusion prevention part 11 is provided at the end of the female thread 10 on the side of the engagement base piece 8.
was formed. The mounting body 7 is formed by drawing, punching, threading, etc. a sheet material of a predetermined thickness, and the overall shape when viewed from the side is approximately T-shaped. By doing so, it is possible to manufacture it at a low cost since special blocking treatment means are not required. Desirably, the outer diameter of the connecting tube 9 is slightly larger than the inner diameter of the connecting tube 3 so that the connecting tube 9 itself can be forcibly fitted into the mounting tube 3, so that the concrete material C that is cast after being fixed is fixed. Take care to prevent it from entering the inside of wiring box B. The protrusion prevention part 11 is
A mounting bolt 12 with a nut 15, which will be described later, is restricted from being screwed into the female screw 10 to the extent that it will not separate unless it is rotated a considerable number of times, and
The tip of the mounting bolt 12 should not protrude outward from the engagement base piece 8. For example, the end of the female thread 10 on the engagement base piece 8 may be crushed, the threads may be bent, or any protrusions may It is formed by providing a plate or welding plates, etc.

使用を節減することができる。 Further, it is desirable that the mounting body 1 does not spin idly when mounted on the wiring box B. For example, since a knockout is usually used as the mounting hole N opened in the bottom side wall B1, the connection remaining after punching is It is obtained by inserting a small piece into the mounting groove 4 in the mounting body 1. In FIGS. 7 and 8, in order to prevent the mounting body 1 from idling after mounting, a pin-shaped mounting protrusion 2A that fits into a small through hole J formed in the bottom side wall B1 is provided. It protrudes from the inner surface of the base 2. The mounting protrusions 2A are arranged in pairs at both ends of the base 2 in the longitudinal direction, which has a rounded, approximately rhombic shape. There is no problem in doing so. In addition, by fitting the mounting protrusion 2A into the small through hole J, a secondary effect of preventing the concrete material C to be poured from entering the wiring box B from the small through hole J can also be obtained. , the use of special closure caps can be saved.
