Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This invention relates to a method of forming a slab with wiring spaces.

[Conventional technology]

Conventionally, steel pipes with drawer openings attached at various places on the upper surface were laid on a deck plate at intervals, concrete was poured over the steel pipes, a pipe duct for electrical wiring was formed in the concrete slab, and the drawer A method has been adopted in which the wire is pulled out from the mouth.

[Problem that the invention seeks to solve]

With the conventional method, the cord could only be pulled out from various drawer openings. Also, wiring work was troublesome as it had to be routed through a duct.

[Means to solve problems]

In order to solve this problem, in the present invention, the prismatic removed objects are laid out in a grid or striped pattern, a concrete slab is poured, and after hardening, the edges of the grooves formed by removing the prismatic removed objects are covered with lids. A supporting edge and a lid are provided.

[Effect]

With this construction, the work of forming the groove and attaching the support edge is a skillful task, and the cost of the support edge and the lid is low, so the overall construction cost is low. Furthermore, wiring costs are extremely low because the floorboards do not need to be moved during wiring work or redecoration work, and all that is required is to open the lid and run the wiring into the groove.

[Example 1] Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

What is shown in FIG. 1 is a rectangular paper tube l. Figures 2 and 3
As shown in the figure, a reinforcing bar 3 is placed on top of the deck plate 2, and long rectangular paper tubes 1 are laid parallel to one direction at 1 m intervals, leaving gaps above the reinforcing bar, and the reinforcing bars 3 are placed at right angles to the reinforcing bars 3. like,
Lay out 1m long square paper tubes and assemble them into a grid pattern. The ends of the paper tube are closed.

Next, a concrete slab 4 is placed up to the level of the upper surface of the rectangular paper tube.

FIG. 4 shows a U-shaped semi-cylindrical support edge 5 made of extruded cement. The size of the outer periphery is formed to be slightly smaller than the above-mentioned rectangular paper tube. M6 is installed above the support edge.

As shown in FIG. 5, after the concrete slab has hardened, the rectangular paper cylinder is removed and a grid-like groove 7 is formed in the remains of the paper cylinder. A semi-cylindrical support edge is installed in the groove and fixed using mortar 8. The top of the concrete slab is smoothed with mortar and leveled with the top of the lid.

A semi-cylindrical wiring space 9 can be formed under the lid.

[Embodiment 2] FIG. 6 shows a frame-shaped support edge 10 made of extruded aluminum. A long piece of material with a 17-character cross section is in the shape of a square frame like a picture frame.

As shown in FIG. 7, the construction method is to form lattice-shaped grooves 7 in the same way as in the previous embodiment, and to form concrete slabs 4 surrounded by the grooves.
A picture frame-like support edge 10 is fixed around the periphery of the frame. A lid 6 is constructed between the supporting edge and the adjacent supporting edge facing each other. Leveling mortar 8 is used on the top surface of the concrete slab to match the level of the top surface of the lid.

A groove 7 under the lid 6 can be used as a wiring space 9.

At the point where you want to pull out the cord, make a hole in the lid and use it as an outlet. Placing outlets and connectors in grooves is also convenient for wiring.

A finishing material such as tile carpet or vinyl tiles is applied on top of the concrete slab constructed as described above, but the lid also serves as a finishing material, so it is possible to omit the finishing material in that area. be. In this case, the finished part of the lid is made higher than the concrete slab.

〔effect〕

Since the present invention is configured as described above, it has the following features.

■ A wiring space is created in the concrete slab by providing a supporting edge in the trench and covering it with a lid.

■ The cord can be pulled out from any part of the lid.

■ Wiring work is easy because the lid can be opened to wire.

■ Remodeling can be done without having to remove the floorboards each time.

■ Since the wiring space is contained within the slab, the total height of the building can be reduced.
