Description

[Detailed description of the invention] This invention prevents the square timbers for fixing the flooring material, which are embedded in the integrally formed synthetic resin foam base material, from expanding, contracting, warping, or peeling from the base material. Regarding flooring materials.

Conventionally, as a flooring material, for example,
However, in this case, the square timber is embedded in a base material made of synthetic resin foam so that at least one surface of the square timber is exposed to the surface of the base material, so the square timber and the synthetic resin are There was a risk that the square timbers would peel off when they were poorly bonded to the foam base material, or when they were subjected to impact, tensile force, shearing force, etc. during transportation or use.

In addition, after being laid on a concrete slab, the square timbers may warp and peel due to water leakage from the floor surface, or due to the difference in expansion and contraction rate between the square timbers and the synthetic resin foam base material due to sudden changes in temperature and humidity indoors and outdoors. There was also a risk of deformation of the flooring material.

Furthermore, when wood is used as a square lumber, due to deformation such as warping of the wood, flatness with the surrounding synthetic resin foam surface cannot be maintained, creating gaps between the wood and the flooring material during construction and use. There was a risk that the planarity of the material would be lost, and the exposed portion of the surface of the square material from the synthetic resin foam base material had to be leveled separately, leading to an increase in manufacturing costs. .

In order to solve these conventional problems, the present invention aims to provide a flooring material in which the expansion, contraction, and warping of the square timbers do not pose much of a problem, and there is no risk of the square timbers peeling off. This is because the square timber is embedded in a synthetic resin foam base material which is integrally formed with at least the longitudinal surface covered with the synthetic resin foam.

The details of the flooring material of the present invention will be further explained below based on the attached drawings.

A piece of wood in a square, irregular shape, or other suitable shape, or a synthetic resin or synthetic resin foam with good nailing properties is placed near the inner upper surface of the integrally formed synthetic resin foam that is the base material shown as 1 in the figure. The square timbers 2 are integrally molded during the foam molding of the base material 1 in the form of a long piece in the length direction of the synthetic resin foam base material 1, or a plurality of short pieces are integrally molded during foam molding of the base material 1, or the square timbers are formed in advance. The square timber 2 is later inserted into the insertion hole and buried with at least the longitudinal surface of the square timber 2 covered with the synthetic resin foam.

When wood is used as the square timber 2, the holding force will not decrease even if the nail is removed and nailed again in the same spot after nailing, so it is preferable to use wood depending on the purpose.

In the figure, reference numeral 3 denotes a mating jack portion optionally provided on the substrate 1.

If the mating jack part 3 is provided on the synthetic resin foam base material 1 in this way, when it is laid on a concrete slab (described later), the contact area between adjacent parts can be increased and the mutual adhesion strength can be increased. Strengthen it,
This is effective in preventing the edges from curling up.

Moreover, regardless of what is shown in the drawings, the square timbers 2 can be embedded in various synthetic resin foam base materials 1.

For example, the main floor base material is laid on a concrete slab 4 as shown in Fig. 2, and the flooring material 5 on top is fixed by nailing two pieces of square timber to form the base floor material layer. It is something that
In particular, in the flooring material of the present invention, the square timber 2 is made of wood or a synthetic resin or synthetic resin foam with good nailing properties, and the square timber 2 is buried with at least its longitudinal surface covered with the synthetic resin foam. Therefore, the square timber 2 will not peel off during transportation or use.

Moreover, since the square timber 2 is waterproof and heat-insulated by the base material 1 made of synthetic resin foam, even after the square timber 2 is laid on a concrete slab 4, etc., water leakage from the floor surface and indoor and outdoor It tends to expand, contract, and warp due to sudden changes in temperature and humidity, but
It became possible to use wood with good nailing properties.

Although not shown, if the surface of the flooring material is printed or otherwise marked to indicate the location where the square timbers are embedded, the location where the square timbers are embedded can be easily identified and is effective in improving workability.

The flooring material of the present invention as described above has square timbers made of wood or synthetic resin foam with good nailing properties inside the base material integrally formed with synthetic resin foam, and at least the longitudinal surface is made of synthetic resin. Since the square timber is buried covered with foam, there is no risk of the square timber peeling off during transport or use of the flooring material, even if the square timber is not separately treated to prevent it from coming off from the base material. Even if the material is warped, it can be used satisfactorily, and the manufacturing cost can be set low.

Furthermore, even when using wood that tends to expand, contract, and warp due to changes in temperature and humidity, at least the longitudinal surface of the wood should be completely covered with synthetic resin foam that has a heat insulating effect. Because of this, it prevents the effects of temperature and humidity changes from directly affecting the wood, and also prevents the wood from expanding, contracting, and warping, thereby preventing the flooring material from deforming.

Moreover, in order to prevent the longitudinal surface of the square timber from being exposed from the base material, the square timber may be integrally molded during foam molding of the synthetic resin foam base material, or it may be buried by later inserting it into a square timber insertion hole previously formed. Since it is possible to omit gluing the square timber to the base material, it can be used even if the surface of the square timber is not completely finished, and it is also possible to optionally omit finishing such as planing on the surface of the square timber, making it economical. The effect is great.

Since the surface of such flooring materials is made of soft synthetic resin foam, even if the area where the square timber is embedded is not specifically indicated, it is easy to check the area where the square timber is embedded, for example by poking it with a drill-shaped object. Not only is this possible, but when the flooring material is installed after it has been laid on a concrete slab, synthetic resin foam is interposed between the flooring material and the square timbers, and unevenness may occur between the temporarily laid subfloor materials. However, the unevenness can be easily adjusted.
