Next, the wiring box 10 is connected to the rear side of the wiring box 10 and a concrete wall 26 as a structural body.
A method of attaching to the concrete wall 26 with the heat insulating material 27 interposed therebetween will be described.

First, a concrete wall 26 as a structural body
In a state in which the heat insulating material 27 is fixedly arranged on one surface, two through holes 28 penetrating the heat insulating material 27 are formed. The through holes 28 correspond to the mounting portions 22 formed at the upper and lower ends of the rear surface of the wiring box 10. Then, one end of the box abutment 24 is cut off from the thin portion 25 so that the length of the box abutment 24 in the axial direction and the thickness of the heat insulating material 27 are substantially the same.

At this time, the thin portion 25 is
Since it is thinner than the thickness of the other parts of 4, it can be easily cut off. Next, the box contact members 24 are inserted into both the through holes 28, and one end of each box contact member 24 is brought into contact with the concrete wall 26. At this time, the thickness of the heat insulating material 27 is substantially the same as the length of the box contact member 24 in the axial direction, and the other end of the box contact member 24 slightly protrudes from the surface of the heat insulating material 27. .

Subsequently, the mounting portions 22 located at the upper end and the lower end of the wiring box 10 are made to correspond to each box contact member 24. Then, the box contact body 2 is inserted through the insertion hole 21.
The fixing nail 23 is inserted into the inside 4, and the fixing nail 23 is guided by the box contact member 24 so as to be orthogonal to the concrete wall 26. Further, the head 2 of the fixing nail 23
3a is hit with a hammer or the like to drive the tip of the fixing nail 23 into the concrete wall 26, and the head 23a of the fixing nail 23 is accommodated in the recess 20. Then, the heat insulating material 27

Claims (10)

[Claims] 1. A box attached to a structural body of a building by a fixing member in a state where a heat insulating material is interposed between the structural body of the building and a box used for wiring such as a cable or piping such as a water supply pipe. And one end abuts on the outer surface of the box, extends from the outer surface of the box through the heat insulator toward the structure, and the other end abuts on the structure to maintain a distance between the two. A box mounting structure for a structure in which a box contact body is disposed such that the box is mounted and fixed to the structure via a heat insulating material by the fixing member. 2. The length of the box contact member in the axial direction is substantially equal to the thickness of the heat insulating material.
A structure for mounting a box to the structure described in 1. 3. The box according to claim 1, wherein the box abutting member is configured to be able to be cut off so that its length in the axial direction can be adjusted. Mounting structure. 4. The structure for mounting a box on a structure according to claim 1, wherein the box contact body is arranged so as to be detachable from a mounting portion formed on an outer surface of the box. 5. The structure for attaching a box to a structure according to claim 1, wherein the box contact body is formed integrally with the box. 6. The box contact body is formed in a tubular shape through which a fixing member can be inserted, and the box is fixed to the structure by inserting the fixing member into the box contact body. A structure for mounting a box to the structure described in 1. 7. The mounting of a box on a structure according to claim 1, wherein the box contact body is formed to have a sharp tip so as to facilitate penetration into a heat insulating material. Construction. 8. In a state where a heat insulating material is interposed between a structure of a building and a box used for wiring or piping, one end abuts on an outer surface of the box and penetrates the heat insulating material. A box abutment disposed between the box and the structure such that the other end of the box abuts in the direction of the structure and the other end abuts on the structure to maintain an interval therebetween. 9. The box abutment according to claim 8, wherein the box abutment is removably disposed on a mounting portion formed on an outer surface of the box. 10. The box abutment according to claim 8, wherein the box abutment is integrally formed on an outer surface of the box.
