Description

[Detailed explanation of the invention] [Field of industrial application] The present invention relates to architectural flooring materials, in particular, it is applied directly to the surface of a concrete structure to form a floor surface, and has many advantages including safety in the event of a fall. This invention relates to a surface material for concrete floors that has a high buffering effect, provides an excellent walking feel, and is easy to install.

[Prior art and its problems]

BACKGROUND ART Conventionally, panel-shaped board materials have been widely used as building materials in the construction field, in which sound absorbing materials such as glass wool and rock wool are filled between the front and back boards to obtain sound absorption and sound insulation effects.

When such boards are used as flooring materials,
The board material itself has poor sound absorption and sound insulation effects and lacks cushioning properties, so it feels uncomfortable to walk on, and it also produces impact noises such as when objects are dropped or jumped, as well as voices and vibrations when children make noise. It has little effect on things that are transmitted and echoed downstairs.

Especially when using conventional panel-shaped boards as flooring material, if the building itself is made of concrete, joists are installed on the concrete floor surface, and the boards are fixed on top of these by nailing. This not only increases construction costs, but also increases the distance between the concrete floor surface and the floorboard surface, which narrows the indoor space accordingly. It is difficult to directly adhere conventional panel-shaped plate materials onto a concrete floor because the surface of the concrete floor is not necessarily flat and has some unevenness.

[Purpose of invention]

In view of this, the present invention has been designed to be able to form a floor surface by directly attaching it to a concrete floor surface, yet it has an excellent walking feel, is safe in the event of a fall, has high cushioning properties, is easy to install, and can save indoor space. The purpose of this work is to provide a surface material for concrete floors that does not cause narrowing.

[Summary of the idea]

In order to achieve the above object, the surface material according to the present invention is provided with a buffer body made of natural, synthetic rubber, or other similar elastic material and having a trapezoidal cross section with a concave portion on the lower surface. A plurality of upper surfaces of the shock absorber are adhered to the back surface of the surface plate material with required spacing and arrangement, and the lower surface of the peripheral leg side formed by the recessed portion of the buffer body is adhered to the concrete floor surface. It is characterized by the fact that

[Example of idea]

Hereinafter, the present invention will be described with reference to embodiments shown in the drawings.

Figure 1 shows the appearance of an example of the surface material for concrete floors according to the present invention, Figure 2 shows the side view of Figure 1, Figure 3 shows the bottom side of the same, and Figure 4 shows the cross section taken along the line shown in Figure 1. It shows.

The concrete floor surface material 1 is composed of a surface board material 2 constituting an upper surface, and a buffer body 3 adhered to the lower surface of this surface board material 2.

The surface board material 2 is made of natural wood plywood, synthetic resin board, metal plate, etc., and has a length of, for example, 300 m/m on one side.
It is standardized into a square shape, and the surrounding two
The side has a protruding ridge 4 in the longitudinal direction of the end face, and the other 2
A concave groove 5 into which the protrusion 4 of the adjacent surface plate material 2 fits is formed on the side.

The upper surface of the surface board 2 is covered with a wood-grain decorative board if it is used directly to form a floor surface, or left as a cloth if it is used to lay down a carpet.

The buffer body 3 is made of natural, synthetic rubber, or other similar elastic material and is formed into a trapezoidal cross section with a recessed portion 3A on the lower surface, and has an upper surface 3B and a peripheral leg formed by the formation of the recessed portion 3A. Part 3
The fiber material 6 is flocked on other surfaces of C than the lower surface 3D by electrostatic flocking or the like. As the fiber material 6, in addition to natural fibers such as wool, silk, and cotton, synthetic fibers such as nylon, vinylon, acrylic, and tetron series, and semi-synthetic fibers such as viscose human silk and acetate human silk are used. The planar shape of the buffer body 3 can be any suitable shape, such as a square as shown in Figure 5, a circle as shown in Figure 6, or a hexagon, rectangle, or ellipse (not shown). However, it is necessary that the peripheral leg portion 3C has a closed horizontal cross section. Furthermore, the above-mentioned peripheral leg portion 3
It is desirable that the cross-sectional shape of C is such that the thickness gradually increases from the upper end to the lower end in order to enhance the load-bearing effect.

As an example shown in FIG. 3, the above-mentioned buffer bodies 3 are integrated by bonding a plurality of flat upper surfaces 3B to the surface of the surface plate material 2 with required spacing and arrangement. The arrangement and number of pieces are selected depending on the target floor surface, and if the floor is a floor on which heavy objects will be placed, it will be dense, and if it is a residential floor where heavy objects are not placed and cushioning properties are important, then Roughly placed.

Since the present invention has the above configuration, as shown in FIG.
The convex strips 4 and concave grooves 5 of the surface plate material 2 of the adjacent surface material 1 are successively fitted and laid while bonding with an adhesive, thereby constructing a floor surface by directly pasting onto the concrete floor surface 7. be able to. In this case, the concrete floor surface 7 usually has some uneven parts, but the peripheral leg part 3C of the buffer body 3 corresponding to the part bends and deforms, so that it can be stretched without any problem, and the joists can be stretched as usual. It can be directly stretched completely flat without using it.

In addition, in order to enhance the vibration-proofing effect, if a vibration-proofing rubber 9 is interposed in the portion in contact with the wall 8, it is possible to further prevent vibrations from propagating through the wall to the upper and lower floors.

By directly applying and sequentially laying the materials on the concrete floor in this way, the surface plate material 2 of each concrete floor surface material 1 constitutes the floor surface, and the resulting floor is placed on the concrete floor surface 7. Even if it is directly tensioned, the flexure of the peripheral leg portions 3C of the shock absorbers 3, 3... attached to the lower surface of the surface plate material 2 provides an excellent cushioning function and exerts an appropriate cushioning effect when walking. The feeling of walking can be greatly enhanced, and the cushioning body 3 has an excellent ability to absorb and alleviate shocks caused by dropping or jumping objects, thereby preventing the impact from being heard downstairs. Since the cushioning body 3 interposed between the surface plate material 2 and the concrete floor surface 7 forms a space in which the inside of the recessed part 3A is sealed as described above, the cushioning properties are further improved, and the concrete floor surface Even if there is some unevenness on the floor 7, it is absorbed by the deflection of the peripheral leg portion 3C of the cushioning body 3, so that a flat floor surface can be constructed.Moreover, the cushioning body 3 is made of an elastic material such as rubber. Since the surface material 1 is standardized, there will be no permanent deformation due to aging, and the floor surface can maintain a flat surface for a long period of time.Furthermore, since the surface material 1 is standardized, it is easy to partially replace it during repairs. .

[Effect of idea]

As explained above, the surface material for concrete floors according to the present invention is provided with a buffer body made of natural, synthetic rubber, or other similar elastic material and having a trapezoidal cross section with a concave portion on the lower surface. A plurality of flat upper surfaces of the shock absorber are adhered to the back surface of the surface plate material at required intervals and arrangement, and the lower surface of the peripheral leg portion formed by the recessed portion of the shock absorber is adhered to the concrete floor surface. As a result, it can be directly installed on the concrete floor surface of a concrete frame without using a base material such as a joist.
Floor construction can be done quickly and easily, reducing construction costs.In particular, even if the concrete floor surface has unevenness, the floor can be laid to adapt to the unevenness, so even if it is laid directly, the floor will have good flatness. surface can be constructed. Furthermore, if natural wood is used for the surface board material, the floor surface can be formed immediately by simply attaching it directly to the concrete floor surface, and the materials used can be kept to a minimum. After installation, the cushioning material on the lower surface provides an excellent walking feel, safety in the event of a fall, sound absorbing and sound insulating effects, and a floor with excellent cushioning properties. Furthermore, since the shock absorbers are arranged in dots on the back side of the surface plate, the amount of buffer used relative to the area of the surface plate can be reduced, compared to a case where a blank elastic material such as a rubber plate is glued to the entire surface. Therefore, the amount of material used for the cushioning body 3 can be significantly reduced, resulting in lower costs, and since each cushioning body 3 is more flexible than a rubber plate or the like, and air is sealed inside, the cushioning properties can be improved. . Furthermore, if the cushioning body is flocked, the rigidity of the peripheral leg portion 3C of the cushioning body increases due to the adhesion of the adhesive for the flocking and the dense adhesion of the fiber material, thereby increasing the load bearing capacity.

In addition, in the illustrated embodiment, the surface material 1 is 300
Although the case of m/m square has been described, it goes without saying that this can also be applied to large-sized surface materials as well, if necessary.
