Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flooring having heat insulation and moisture resistance.

[0002]

2. Description of the Related Art When constructing houses and other flooring materials,
First, it was common practice to construct joists at intervals of 30 to 45 cm on the large pulley, and to fix the flooring on the joists using fixing means such as nails or an adhesive. When it is necessary to apply a heat insulating material, it is common practice to insert a relatively hard heat insulating material such as polystyrene foam between the joists, and then to install a floor plate on the upper surface of the joists.

[0003]

However, these conventional construction methods have the following drawbacks. A separate heat insulating material installation process is required. In addition to the construction of the floor material, a process of constructing a heat insulating material is required. Construction accuracy of joist is required. Since the insulation is dropped between the joists, the interval between the joists must be set accurately. Even if the heat insulating material is molded to a predetermined size in advance, the joists are installed by workers at the site,
There is a risk that some dimensional deviation may occur. In this case, if the intervals are irregular, the heat insulating material may fall off. In order to prevent the heat insulating material from falling off, it is certain to use a fixing means such as a tucker. However, the number of working steps is increased, and a gap is formed, and a portion where the heat insulating property is deteriorated is sometimes generated. That is,
Variations tend to occur depending on the installer.

[0004] There is a possibility that a trouble may occur due to moisture from under the floor. Actually, when completely fitted, there is almost no gap between the flooring materials, but in reality, the flooring material itself slightly bends,
In many cases, a gap of about 0.5 mm is generated due to misalignment of the marking line during construction and other reasons. Even if an appropriate moisture-proof layer is formed on the back of the flooring material, this gap causes moisture from under the floor to penetrate inside the flooring material, expands and pushes up, causing warpage and other problems caused by moisture. Often.

[0005]

For the above reasons, according to the present invention, it is possible to construct a flooring material without installing a flooring material and a heat insulating material separately, and at the same time as a flooring material, a heat insulating material can be constructed.
In addition, it is an object of the present invention to provide a floor material that can be firmly constructed without a gap between the floor materials and does not reduce heat insulation.

In the heat-insulating flooring material of the present invention, a joist is integrally provided at both ends of the lower surface of the flooring material, and a heat insulating material is arranged on the back surface of the flooring material. It is characterized in that fitting means consisting of fruits is provided.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, a floor material stretched on an upper surface of a joist (hereinafter, this floor material is referred to as a floor plate material) is not particularly limited, and is usually used as a floor plate material in this kind of field. Can be used. Therefore,
The floor panel may be a single floor panel or a laminated panel. Since the surface of the floorboard is used as a floor as it is, a laminate of decorative veneers and the like is used.

A joist is integrally attached to both ends of the lower surface (back surface) of the floorboard. Normally, floor slabs are installed on the upper surfaces of joists provided at predetermined intervals. Since the floor boards are abutted against each other at the position of the joists, the width of the joists is such that the ends of both floor boards can be nailed or bonded and fixed. In the case of the flooring material of the present invention, a joist is fixed to an end of the lower surface of the flooring material, and the side end surface of the joist together with the end surface of the flooring material is connected to the flooring material end surface of the other flooring material and the side end surface of the joist. Since the construction is performed by abutting, the width may be narrower than the conventional joist.

In the case of the present invention, since a floor material in which a joist is integrated with a floor plate material is constructed on a large scale, a part below the mating surface of the floor material and the floor material may be directly under the floor. Therefore, it is preferable to provide a convex (male) or concave (female) on the end surface of the floor plate and / or the side end surface of the joist so that the fruits are fitted to each other. Actually, if necessary, an airtight material such as a linear or belt-like elastic sheet material such as rubber or plastic for closing the gap at the time of fitting is arranged to ensure the fitting between the convex and the concave. Therefore, it is preferable to secure moisture resistance and heat insulation. More specifically, as the airtight material, a coating layer of asphalt, plastic paint, or the like may be provided in addition to a film of elastic rubber or plastic, a plastic foam, asphalt-impregnated paper, or the like. Further, a sealing agent such as a putty or a caulking agent may be used for the airtight material in some cases. The hermetic material is usually provided on the concave side, but may be provided on the entire surface or a part of the male or female member or both, by applying, bonding, or other method to provide a continuous line in the length direction.

The joists provided on the lower surface of the floorboard are provided so that the end surface of the floorboard and the side end surfaces of the joists are flush with each other. Joists are usually provided at intervals of 30 to 45 cm on the pulling,
The width of the floorboard does not necessarily have to be the same as the width at which the joists are provided, and can be the width and length of ordinary building materials. In this case, it is preferable to provide a joist in the middle in addition to both ends of the floorboard material in accordance with the width in which the joist is usually provided.

In the present invention, a heat insulating material is provided on the back surface of the floorboard.
This heat insulating material is fitted so that there is no gap between the joists. Examples of the heat insulating material include foams such as polystyrene foam, polyurethane foam, polyethylene foam, and phenol resin foam, and natural or inorganic fiber mats such as felt, glass wool, and rock wool. A closed-cell, flame-retardant plastic foam such as a polyurethane foam or a phenolic resin foam is particularly preferred in view of processability, heat insulation, and moisture resistance. It is not necessary to use only one kind of heat insulating material, and it may be used in an appropriate combination, for example, by using an air-impermeable plastic foam and a gas-permeable inorganic fiber mat in a stacked manner. By using such a combination, it is possible to obtain effects such as prevention of moisture from under the floor.

When the heat insulating material is a moisture permeable or moisture absorbing material such as glass wool or fiber mat, the heat insulating material may be used in combination with the heat insulating material having a moisture proof property as described above, or may be provided with a moisture proof film or Sheets may be laminated, and a moisture-proof material made of a moisture-proof film or sheet may be stretched between the joists including the joists. The method of fixing the joists of the flooring material of the present invention in a large scale may be performed by means such as nailing or bonding which is usually performed. Since the surface of the heat-insulating floor material of the present invention becomes the floor surface as it is, in order to protect the surface at the time of construction, a plastic film,
It is preferable to provide a decorative surface protection material such as a foamed plastic sheet, a nonwoven fabric, and kraft paper. It is preferable that the decorative surface protective material be pasted with an adhesive or a pressure-sensitive adhesive having a property that can be easily peeled off from the floor material surface after construction.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings, but the present invention is not limited to these embodiments.

FIG. 1 is a sectional view showing an example of a flooring material showing a basic structure of the present invention. A base material 2 such as a plywood having a decorative material 1 bonded and integrated on the surface is used as a flooring material. A joist 3 is fixed to both ends of the lower surface of the base 2 and a heat insulating material 4 is filled between the joists 3a and 3b. One of the joists 3a of this heat-insulating floor material is processed with a convex 5 and the other of the joists 3b is processed with a concave 6; in this case, the concave 6 is provided with an airtight material 8. Further, a decorative surface protective material 7 is laminated on the surface of the decorative material 1, and the protective material 7 can be easily removed after the completion of the construction, so that a weak adhesive double-sided tape or a weak adhesive,
Affixed with a peelable adhesive or the like. As the protective material 7, a plastic sheet, a fiberboard such as a thin MDF, paper, or another sheet is used.

FIG. 2 is a view showing a state in which the floor material of FIG. 1 is constructed. In the construction, the convex portions 5 and concave portions 6 of the joists 3a and 3b are fitted. In the case of this example, the airtight material 8
Is provided, airtightness between the convex 5 and the concave 6 is secured by the fitting of the convex 5. Various materials can be considered as the airtight material 8, but those having a sufficient elasticity such as rubber and plastic foam are preferable, and it is more preferable that the airtight material is applied concavely and the adhesive or adhesive is applied convexly. It is effective. The surface on which the adhesive or the adhesive is applied may be covered with release paper or the like, and may be peeled off at the time of use. By using an airtight material to seal the gap generated between the convex 5 and the concave 6, a moisture-proof layer can be formed over the entire back surface of the flooring.

FIG. 3 shows another embodiment of the flooring material of the present invention. In the case where a heat-permeable material such as glass wool or felt is used, a moisture-permeable sheet or film such as a plastic film is used. This is an example in which a moisture-proof material 9 made of is adhered between the joists 3a and 3b. In the example of FIG. 3, the moisture proof material 9 is attached including the surface of the joist 3, but the moisture proof material 9 may be attached only to the surface of the heat insulating material 4. FIG. 3 shows an example in which the air layer 12 is provided between the heat insulating material 4 and the moisture-proof material 9. However, the heat insulating material may be filled up to the air layer 12.

FIG. 4 shows an example of a floor material in which the end surface of the base material 2 as the floor plate material and the side end surface of the joist material 3 are not flush with each other but are slightly shifted. In the case where the end faces of the base material 2 and the joist 3 are not the same as described above, a moisture-proof effect can be obtained by performing a moisture-proof treatment on the surface where the base 2 and the joist 3 overlap. In the case of this example, the convex portions 5 and the concave portions 6 can be omitted as desired.

FIG. 5 is a diagram showing an example of construction. At the time of construction, a floor material is usually constructed after applying a joist material or a heat insulating material on the large-scale pulling 10. However, in the heat insulating floor material of the present invention, the floor plate material and the joist material 3 are bonded and integrated in advance. Therefore, the nail 11 is fixed to the large puller 10 by using an adhesive together with the convex portion 5 of the joist 3, and the concave 6 is fitted to the nail 11. In addition, the heat insulating material 4 and the floor material can be simultaneously constructed. After the construction of the flooring material is completed, it is general to start the construction of other indoor building materials, but after these constructions are completed, the protective material 7 is removed and the decorative surface of the flooring material is removed. The construction can be completed without damage.

[0019]

The heat insulating flooring material of the present invention has the following effects. Insulation improvement: Unlike conventional insulation construction at construction sites, the insulation is cut or molded with high precision at a factory or the like and then fitted between the joists on the back of the floorboard, Not only a heat insulating layer is formed, but also high-precision construction with almost no gap is possible. Therefore, there is no possibility that a so-called "heat bridge" is formed due to lack of the heat insulating material, and the heat insulating property is improved.

Improved moisture-proofing property Since an appropriate moisture-proofing layer is formed on the back surface of the floor material, even if the high-humidity state under the floor continues, the gap is completely closed, so that the moisture reaches the wood part. do not do. Therefore, swelling of the wood (floor board) due to moisture does not occur, and there is no risk of troubles such as pushing up, warping, squeaking noise, mold, decay, and stains caused by moisture. Reduction in the number of installation steps Since the installation step of the heat insulating material and the installation step of the floor material can be performed at the same time, and the installation of the heat insulating material can be performed without skill, the work can be performed by ordinary workers. The makeup surface is not easily scratched. Since the decorative surface is protected by the protective material 7, there is little possibility that the decorative surface will be damaged when other indoor building materials are installed after the floor material is installed.

As described above, the present invention has been described mainly on the construction of flooring on a normal house where a joist is constructed on a large scale. However, the invention can also be used as a flooring on a concrete floor surface of an apartment or the like. In addition, the construction has many advantages such as the fact that it is possible to perform the construction simply by laying the flooring material and / or the joist material in the same manner as the conventionally known laying floor material due to the irregularities provided on the floor material.
