Abstract

(57) [Abstract] [Problem] To obtain a wall end cover with a fixture which does not require the trouble of a wall end cover of a buried synthetic resin pipe in wall concrete for electrical installation work. [Solving Means] A cover fixing piece 20 capable of fixing the wall end cover 8 to the support rod 2 of the temporary frame is attached or formed integrally,
Engage with the support rod 2 and fix with bolts or binding wires.

Description

[Detailed description of the invention]

[Technical field to which the present invention pertains] In the electrical installation work for a new building such as a building, a synthetic resin pipe is buried together with a box in a concrete wall. However, the present invention is intended to draw out the synthetic resin pipe from the wall. The present invention relates to a cover with a fixing device to be supported.

[Conventional technology] In the concrete wall construction process, first, a leading temporary frame on one side is built by attaching a support rod, then a wall reinforcing bar is assembled, a box for electric work and a synthetic resin pipe are attached, and the leading temporary frame is attached. At this time, fix the box and wall end cover with nails, etc., but temporarily fix the rear temporary frame side to the wall reinforcement, drill holes after the rear temporary frame is built, pull with bolts or wires, and It was fixed to a frame so that it would not move when casting concrete.

[Problem to be Solved by the Invention] Since the inside of the wall cannot be seen when the rear temporary frame is built, a mark is made on the floor so that the position of the wall end cover can be recognized, and a hole is made in the rear temporary frame. However, the only way to fix it was to feel groping, which required not only skill but also to make a hole in the temporary frame material, remove concrete, and remove bolts.

[0004] The wall end cover of the present invention is intended to be a wall end cover that is fixed when the preceding temporary frame and the wall reinforcement are completed, and does not require any modification even when the rear temporary frame is built.

[Means for Solving the Problems] In order to achieve the above-mentioned object, even if the wall end cover is fixed to the reinforcing bar, the reinforcing bar moves at the time of concrete casting. If it is fixed to the support rod according to the thickness of the wall, it will not move even when concrete is poured.

In order to fix the wall end cover to the support rod, the wall end cover can be firmly fixed by tightening with a bolt, but can be fixed with a binding wire in a place where a driver or the like cannot be used.

[Embodiment of the Invention] An embodiment will be described with reference to the drawings. FIG. 1 is for explanation of the prior art, and a preliminary temporary frame 1 is constructed by attaching a support rod 2 to a support pipe 3, a support pipe retainer 4, and a nut 5, and then attaching a wall reinforcing bar 6. In the electric work, the synthetic resin pipe 7 and the wall end cover 8 are connected by a connector 9 and fixed to a preceding temporary frame with a nail 10, and after the concrete is cast, the cable is pulled out. Is to temporarily fix the wall end cover 8 to the wall reinforcing bar 6, make a hole 13 after the rear temporary frame 12 is built, and pull it toward the rear temporary frame 12 with a wire 14 or the like. A common method is to keep it.

FIG. 2 shows an example of the construction of the wall end cover of the present invention. A cover fixing long piece 15 is provided on the back side of the wall end cover 8 on the side of the preliminary temporary frame 1, and the bolt 1 is attached to the support rod 2. 6, the rear temporary frame 12 side shows an example in which the cover fixing short piece 17 is sandwiched between the support rods 2 on the upper part of the wall end cover 8 and fastened by the binding wire 18 or the like. However, if it is fitted to the stopper 19 attached to the support rod 2, it can be made to approach the rear provisional frame 12 without protruding.

FIG. 3 is a detailed view of one embodiment, in which a cover fixing piece 20 having a shape whose tip is sandwiched by a support rod 2 is integrally formed with a wall end cover 8 having a connector 9 attached thereto. It is configured.

FIG. 4 is a detailed view of one embodiment, in which the front end of the cover fixing piece 20 has a binding wire cutout 21 so as to be fastened by a binding wire or the like, and the front side of the wall end cover 8. In all cases, the curing tape 22 is applied in the same manner.

[Effects of the Invention] After the wall end cover is attached to the frame side once, it is not necessary to make any further changes after that, so that there is an effect of labor saving.

[0012] Since it is also attached to the preceding temporary frame side and there is no need to hit nails or the like, there is no damage to the temporary frame and no need to process nails.

Since no holes are formed in the temporary frame, it contributes to reuse, and no dust such as chips is generated, so that it does not enter concrete.
