Abstract

PURPOSE:To dispense with the use of a heat insulating material, and also to enable work to be carried out by persons other than experts such as furnishers and carpenters. CONSTITUTION:Dry sand 11 for adjusting the horizontal level is scattered and leveled, while avoiding the piping part 3 arranged on a concrete slab, and then styrene foam 5 to which, and adhesive has been applied is spread all over thereon. Further, on the styrene foam 5, two sheets of relatively thin synthetic timbers 7, 7 capable of being cut by a cutter or the like are laminatedly joined and fixed. Then, on the synthetic timbers 7, 7, a floor finishing material 9 such as flooring is stuck. Thereby, the finishing work of a concrete floor can be facilitated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction method for finishing a floor on a concrete slab surface.

[0002]

2. Description of the Related Art In a building made of reinforced concrete or steel frame, a large pull is passed to the surface of the floor slab, and joists are formed on it. The water supply pipes and hot water supply pipes were laid in the space created between the floor slab and joists by pulling. Finally, the plywood was nailed to the joists, and a finishing material such as flooring or carpet was attached to the surface of the plywood.

[0003]

SUMMARY OF THE INVENTION According to the conventional technique, the large pull is taken and sized so as to be tensioned between the inner walls, and the large pull is fixed to the floor slab with nails and bolts together with the joist, It was necessary to adjust the floor level with Daihiki and Jouta. For this reason, there is a drawback that only a person having a skill such as a carpenter can finish the floor. Further, in the process of finishing the floor, it was also essential to check whether or not the nails that compose the floor did not damage the underfloor piping.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a finishing construction method for a concrete floor that does not require inspection by a technician or the presence or absence of pipe damage.

[0005]

In order to achieve the above-mentioned object, a method for finishing a concrete floor according to the present invention is to spread a plate-shaped Styrofoam on a concrete floor while fixing it with an adhesive, and spread it on a synthetic wood board. Are laminated while being bonded with an adhesive, and a floor finishing material such as flooring or carpet is further applied to the surface of the synthetic wood board.
Alternatively, before the step of spreading the plate-shaped Styrofoam on the concrete floor for level adjustment, sprinkle dry sand on the concrete floor to adjust the horizontal level of the Styrofoam or the level of the concrete floor surface, and then spread the Styrofoam. Of.

[0006]

[Function] Styrofoam can be easily cut with a cutter knife without using a saw, has high heat insulation, has a soundproofing effect, and is lightweight, so that the load applied to the floor slab can be reduced as compared with the conventional construction method. In other words, it has achieved weight reduction compared to large pulls and joists and heat insulating materials, and at the same time has the effect of sound insulation and heat insulation. In addition, the work is mainly done with a cutter knife and an adhesive, and for synthetic wood boards, adjustment work is carried out by cutting with a saw on the spot where the site alignment is required. However, if the size of the floor is measured in advance and the size of the synthetic wood board is processed, the cutting work by the site alignment becomes unnecessary. Since the amount of bending of the synthetic wood board is extremely small and the load is evenly distributed on the styrofoam that is the base of the floor, the softness of the styrofoam does not matter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described in detail below with reference to the drawings. 1 and 2 are sectional views showing a floor constructed by the method of the present invention. In the case of FIG. 1, the styrene foam plate 5 is spread over the surface of the concrete slab 1 by an adhesive agent so as to avoid the water supply pipes, hot water supply pipes, and other pipes 3 arranged on the surface of the concrete slab 1. is there. In the figure, a styrofoam plate 5 having a thickness larger than the diameter of the pipe 3 is spread. The size of the Styrofoam plate 5 is cut by a cutter knife according to the state of the site. Next, a synthetic wood board 7 in which a synthetic resin adhesive or a synthetic resin and wood fiber are mixed and compression-formed
On the styrofoam plate 5. This synthetic wood board 7
Is also fixed to the polystyrene foam 5 with an adhesive. Synthetic wood board 7
However, in the present embodiment, two relatively thin synthetic wood boards 7-7 are vertically stacked for ease of handling in this embodiment. This is because a thinner one is advantageous in terms of carrying and cutting. These are also fixed to each other so as to be fixed with an adhesive. Finally, a flooring 9 made of natural wood is stuck on the synthetic wood board 7.

The embodiment shown in FIG. 2 differs from the construction method shown in FIG. 1 in that there are many steps described below. That is, before laying the Styrofoam plate 5 on the surface of the concrete slab 1, dry sand 11 is placed on the surface of the concrete slab 1.
Is sprinkled. Specifically, an adhesive is applied to the surface of the concrete slab 1, and dry sand 11 is sprinkled on the surface of the concrete slab 1 to level it evenly, and then the styrofoam plate 5 with the adhesive applied to the back surface is placed on the dry sand 11. It is laid on the floor. Subsequent steps are the same as those in the embodiment shown in FIG.

[0009]

As described in detail above, according to the method for finishing a concrete floor according to the present invention, by spreading the polystyrene foam on the concrete floor by adhesion, the conventional large pulling or joists are not used. Therefore, there is an effect that the floor base can be constructed without being a carpenter, and the heat retaining ability can be secured without particularly laying a heat insulating material. Furthermore, synthetic wood boards are placed on top of styrofoam, and since these are fixed to the styrofoam with an adhesive, when the finishing material to be attached to the surface of the synthetic wood boards is flooring, of course, even if it is a carpet. The concentrated load applied to the floor surface is evenly received by the synthetic wood board, and the use of Styrofoam is fully effective. Furthermore, even if the floor slab (concrete floor) surface is not carefully finished by a plasterer, or when it is necessary to adjust the Styrofoam surface level according to the diameter of various pipes, the floor slab should be leveled with dry sand. In addition to the effect that the level can be easily adjusted, the use of nails eliminates the risk of pipe punching.
