Abstract

PURPOSE: To reduce cost, to extend the tolerance of a dimensional error at the time of the machining of a floor board and to improve productivity and quality by forming a groove to the underside of the floor board and joining the mutual joining sections of the floor boards by fittings through a cushioning material between the upper clearances of the joining sections of the floor boards. CONSTITUTION: The upper sections of the joining sections of floor boards 10 are chamfered 11, inserting grooves 12 for fittings 14 are formed to an underside, and a tongue section 13 for joining is formed to a peripheral section. The tongue section 13 for joining is composed of a male section and a female section at that time, the male section and the female section are connected to prevent displacement in the vertical direction of the mutual floor boards 10, and the fittings 14 are inserted into the grooves 12 in the undersides of the floor boards 10 to obviate displacement in the horizontal direction. A cushioning material 15 is laid on the joining sections at that time, and the joining sections are filled with the cushioning material 15 when there is an error in the dimensions of the floor boards 10 as a dimensional adjusting material and at the time of a dimensional change due to a temperature change and the absorption and discharge of moisture.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floorboard construction method capable of being constructed even if there are some errors in the dimensions of the floorboard of a building.

[0002]

2. Description of the Related Art Conventionally, a simple construction method such as laying has been studied in a room where floor heating and hot carpets are used, or in a room where humidity changes drastically. Then, as shown in FIG. 3, the construction method is such that the actual joining portion 21 formed on the peripheral edge of the floor plate 20 is fitted and the tip is bent into a groove 23 formed on the lower surface of the floor plate 20 in a dogleg shape. This is a method of fitting both hooking portions 24 of the metal fitting 25 provided with the hooking portions 24 described above, and fixing the adjacent floor plates 20 so that no gap is created between them.

[0003]

However, in the above-mentioned conventional method, the processing position of the groove 23 on the lower surface of the floor plate 20 for fixing at both ends of the metal fitting 24 is the groove 2.
If the three members are too open, the metal fittings will not be caught, and if the three metal members are short, a gap will be opened easily between the floor plates 20. Therefore, in order to securely fix the metal fittings 24, an error in the machining accuracy of the distance X between the grooves 23 is ± It was necessary to suppress it to 1.0 mm or less. That is, it is necessary to suppress the error of ± 0.5 mm or less for one floor plate, which requires high processing accuracy, and there are problems such as a high defective rate of the floor plate, poor productivity, and difficult management. . The present invention has been made in view of such circumstances, and it is an object of the present invention to widen the allowable range of dimensional error during floorboard processing, improve the productivity of floorboard processing, and reduce the cost.

[0004]

A method according to the above-mentioned object.
The floor board construction method described above is a construction method in which a groove is formed on the lower surface of the floor board and the floor boards are joined together by metal fittings, and a cushioning material is interposed in the upper gap of the joint portion between the floor sheets to join them.

[0005]

In the floor board construction method according to claim 1, since the cushioning material is laid in the upper gap of the joint,
Even if there is some error in the size of the floor plates, the cushioning material at the joint expands and contracts, so that the gap between the floor plates can be constantly filled.
As a result, the tolerance range of the dimensional accuracy of the groove interval for fixing with the metal fittings on the bottom surface of the floorboard is expanded, the rate of defective floorboards is significantly reduced, productivity can be increased, and overall cost reduction is achieved. It will be possible. Further, even when the floorboards change in size due to temperature change or moisture absorption / release, the gap between the floorboards can be always filled with the cushioning material.

[0006]

Embodiments of the present invention will now be described with reference to the accompanying drawings to provide an understanding of the present invention. 1 is a side sectional view of a floorboard to which a floorboard construction method according to an embodiment of the present invention is applied, and FIG. 2 is an explanatory view showing a construction state of the floorboard.

As shown in FIG. 1, the upper portion of the joint portion of the floor plate 10 is chamfered 11, and a groove 12 into which a metal fitting 14 is fitted when the floor plates 10 are joined is formed at a predetermined position on the lower surface. The real part 13 for joining is formed in the part. The real part 13 for joining should just be a fitting type | mold, comprising a male part and a female part. At the time of joining, the actual joining portion 13 of the peripheral edge portion is fitted to prevent the vertical displacement of the floor boards 10 from each other, and the metal fitting 14 is provided in the groove 12 on the lower surface of the floor board 10.
To prevent the floor boards 10 from being displaced in the horizontal direction.

A cushioning material 15 is laid at the joint,
The cushioning material 15 functions as a dimension adjusting material, and when there is an error in the dimension of the floor board 10, or when the floor board 10 has a dimension change due to a temperature change or moisture absorption / release, the cushioning material 15 can always fill the gap. It is like this. The material of the cushioning material 15 may be a rubber material such as neoprene or chloroprene, vinyl chloride, or foamed plastic having a foaming ratio of about 2 to 3, but any material having a cushioning property can be used.

Next, referring to FIG. 2, the joining state of the joining portions of the floorboards 10 will be described using concrete numbers. When the floorboards 10 are processed according to the dimensions (A), the gap a between the floorboards 10 is 1.5 mm. Floor board 10
When the floor boards 10 come close to each other at the time of joining (B), the gap b becomes 0.5 mm, and the cushioning material 15 contracts and extends upward. When there is an error in the dimensions of the floor boards 10 and the floor boards 10 are separated from each other at the time of joining (C), the gap c becomes 2.5 mm, and the cushioning material 15 becomes laterally flat.
As a result, the error of the distance X between the grooves 12 has an allowable range of up to ± 2.0 mm, and an error of ± 1.0 mm is allowed for one floor plate. Therefore, ± 0.5 per floorboard
As compared with the conventional method in which only an error of mm is allowed, a double error is allowed.

The floor board 10 is composed of a board having a thickness of about 9 to 12 mm, which has a veneer or a decorative sheet on its front surface, and a vinyl chloride resin sheet or viscoelastic asphalt having a large specific gravity of about 2 to 3 mm on the back surface. A modified rubber sheet or the like is attached and configured.

The cushioning material 15 can be colored in various ways, and by using it as a joint material for the floor board, a streak pattern on the floor surface can be created and a wide design can be produced.

[0012]

In the floor board construction method according to the first aspect of the present invention, since the joining portions of the floor boards are fitted to each other and the adjacent floor boards are connected by the metal fittings, the floor boards are not displaced by vibration or the like. Since a cushioning material is installed in the upper gap of the joint between the floorboards, even if a dimensional error may occur during processing of the floorboards, or if the floorboards undergo a dimensional change due to moisture absorption / release. The cushioning material can always fill the gap.
Further, by providing the cushioning material, the allowable range of the dimensional accuracy of the intervals of the grooves for fixing with the metal fitting is expanded, and the defective rate of the floor board is significantly reduced. And productivity can be raised and cost can be reduced as a whole.
