Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a method of constructing a flooring material on a concrete floor surface.

[Conventional technology]

In conventional construction of flooring materials on concrete floor surfaces, the flooring material is generally installed by placing joists and then nailing or gluing the flooring material onto the joists.

[Problem to be solved by the invention]

Naturally, concrete floors have uneven surfaces, and as mentioned above, when installing floor joists, the joists are lifted up in the uneven recesses, making the squeaks that tend to occur on joist floors even more likely to occur. Become.

Also, it takes time to assemble the joists and lay the floor. For this reason, direct pasting construction, in which flooring is applied directly to the floor surface with a short construction period, has become popular in recent years. This method uses adhesive to install flooring materials such as wooden flooring materials and synthetic resin tiles on the floor surface, but misalignment occurs in the mating surfaces of the flooring materials due to unevenness.

On the other hand, the sound-absorbing, heat-insulating and heat-retaining properties were not sufficient. In order to solve these problems, a foam material is attached to the back side of the flooring material to absorb unevenness and contribute to improving sound absorption and heat insulation.

However, since the scaffolding is made of weak foam material, when a heavy load is applied, that part sags, causing the floor itself to become uneven. In addition, there remains the problem that the foamed material that has been compressed under long-term load is no longer able to restore its original shape.

[Means for solving problems and their effects]

The present invention adopts the following construction method in order to solve the problems of the above flooring construction method.

That is, after applying the adhesive 2 on the concrete floor surface 1, a honeycomb 3 made of a material that deforms when it comes into contact with an uneven surface of the subfloor material is laid so that its cell voids 3a are perpendicular to the surface of the subfloor material. Furthermore, a floor material 5 with adhesive 4 applied to the back surface of the honeycomb 3 is applied.
The purpose is to install

By adopting the above-described configuration, the present invention allows the honeycomb 3 to adapt to the unevenness of the concrete floor surface 1, and allows for easy construction of a flooring material with good heat insulation and heat retention properties.

[Explanation of Examples]

Examples of the construction method of the present invention will be described below.

First, the adhesive 2 is applied onto the concrete floor surface 1 that has been cast and formed in advance.

As the adhesive 2, vinyl acetate type, ethylene vinyl acetate type,
Rubber-based, asphalt-based, cement-based materials, etc. are used.

Next, the honeycomb 3 is laid so that its cell voids 3a are perpendicular to the concrete floor surface 1.

The honeycomb 3 may have any cell cross-sectional shape, and may be either an expanded type or a preformed type.

The honeycomb 3 is coated with a synthetic resin, impregnated with a synthetic resin, and coated with an antiseptic and anti-vibration agent to make it waterproof, antibacterial, and anti-microbial, as required.

In addition, as shown in FIG. 2, the cell voids 3 of the honeycomb 3
A composite honeycomb with improved sound absorption and heat insulation and heat retention effects may be used, the interior of which is filled with a synthetic resin foam material.

Furthermore, the honeycomb 3 may have a surface plate 6 such as paper, a rubber plate, an aluminum plate, an asbestos board, or an FRP plate adhered to one or both sides of the honeycomb 3 as shown in FIG. Use the same base material as the base material constituting the.

Next, on the surface of the honeycomb 3, a bedding material 5 is applied with an arbitrary decoration on the surface and actual processing such as male and female seeds on at least two end sides or four end ends, respectively, and an adhesive 4 is applied to the back surface of the honeycomb 3. Apply and lay.

The adhesives 2 and 4 used are vinyl acetate-based, ethylene-vinyl acetate-based, rubber-based, asphalt-based, cement-based, and the like.

In this way, the flooring material is successively laid and fixed by thrusting or fitting the end surface of the flooring material or each fruit formed at the end portion thereof.

〔Effect of the invention〕

(a) By applying an adhesive to the concrete floor surface 1 in advance and laying the honeycomb 3 and the floor material 5 coated with the adhesive 4, construction can be carried out easily and in a short time.

(b) The floor material 5 is fixedly and integrally formed on the concrete floor surface 1 via the honeycomb 3, and the honeycomb 3 itself has high compressive strength and shear strength, and does not compress and fail under heavy loads.
On the other hand, since the compressive strength of the individual cell walls that make up the honeycomb is low, some of the cell walls that come into contact with the unevenness of the concrete floor surface 1 are deformed, so that they adapt to the unevenness and there is no misalignment at the abutting parts. .

(c) Since it has the cell voids 3a or the cell voids 3a filled with the synthetic resin foam material 7, it has a sound absorption and heat insulation effect, and when it is used on the second floor, for example, the impact sound transmitted to the downstairs is reduced.

(d) Since no joists are used, there is no creaking.
