Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a floor material fastening structure.

<Prior art> Generally, as a fastening structure to a base material such as a flooring board or a large laminated floor board used as a finishing material for a living room floor in a general home or a large area floor of a gymnasium, it is generally used. A so-called flooring construction method or a special floor construction method is known.

However, when the flooring is applied by the former flooring construction method, each of the floor boards is often warped or the entire floor is largely curled up. For this reason,
Especially for floor covering of a large area, a special floor construction method is usually used.

This special floor construction method includes steps such as adhesive, brain nailing (or cerebral screw fixing), and embedded trees (so-called dowels).

That is, in the case of, for example, constructing a flooring board by this special method, first construct a joist base, then attach a discard board on this joist, and after applying a floor material with the adhesive applied on this discard board, Drive a hidden nail to the side of the flooring,
In addition, make a hole in the top of the floor material for the top of the floor, and then tap the top of the top with nails or screws to fix the top of the floor. A procedure such as painting the material surface is adopted.

Also, in the case of a large laminated board, after attaching the floor material directly on the joists, make a cerebral dowel hole on the top surface of the floor material. The steps such as driving in to fill the dowel holes, then smoothing the surface of the floor material by siding, and then painting the surface of the floor material <Problems to be solved by the invention> However, in the above conventional method, the floor material is Since it requires a complicated process such as drilling a dowel hole on the upper surface, driving a dowel hole into the dowel hole, or screwing the dowel hole into the dowel hole, and then filling a dowel hole to fill the dowel hole. However, there is a problem that the buried tree may be removed.

Further, since the surface of the flooring material becomes a rough surface or an uneven surface due to dowel drilling or embedding, the surface of the flooring material must be siding or painted, which also complicates the process.

Furthermore, since the side surface of the floor material is in contact with the adjacent floor material and the back surface of the floor material is in contact with the joist or the discarding plate, there is a possibility that floor squeaking may occur when walking on the floor material.

This invention maintains a strong and reliable fixing force between the flooring and the foundation, which are the basics of fastening, and the flooring, and it can be installed in a short time, and the floor squealing during walking can be prevented. It is an object of the present invention to provide a floor material fastening structure that can be prevented.

<Means for Solving the Problems> In the floor material fastening structure according to the present invention, the end portion of the first floor material having the female fruit portion is fixed to the joists provided at a predetermined interval on the base. The first and second floor materials are fixed by a tool and an elastic fitting member fixed to the side surface of the second floor material is inserted into the female part of the first floor material so as to cover the fixing tool. In a fastening structure for a floor material in which the two are engaged with each other, an engaging piece inserted into the female portion of the first floor material and a locking piece interposed between the second floor material and the joist And a cushion piece interposed between the first floor material and the second floor material is used as the elastic fitting member.

The elastic fitting member may be made of an elastic material such as rubber or synthetic resin. Further, in order to have strength, a hard material such as vinyl chloride resin or steel may be used as the core material, and the surface of the core material may be coated with an elastic material such as rubber. Further, in order to make it difficult for the elastic fitting member to come off when it is fitted into the recess formed in the female part of the adjacent flooring material, a protrusion such as the tip of an arrow may be formed on the surface of the tip part. More preferable. Furthermore, the above-mentioned recessed portion at the end of the floor material may have a shape corresponding to such a protrusion.

In addition, joist steel and wood joists are conceivable as the joists, and screw fasteners and nails can be given as the fixing tools.

<Operation> With the above-described structure, in the present invention, the elastic fitting member is used as a so-called male portion, and the tip end of the elastic fitting member and the recess formed in the female portion of the floor member are adjacent to each other. By joining the floor materials to each other, the pulling force of the screw or nail and the elastic fitting member against the force in the horizontal direction, and the shearing force of the screw or nail and the elastic fitting member in the vertical direction, respectively. It resists, which ensures that adjacent flooring materials are secured together.

For this reason, the floor material can be securely fixed without the need for conventional nailing with a nail or screwing of a cerebral screw, and therefore the steps such as dowel hole drilling and dowel filling with a buried tree are not required. You will be able to fasten the flooring to.

Further, the second floor material acts so as to contact both the first floor material and the joist through the elastic fitting member.

<Embodiment> An embodiment of the present invention will be described below with reference to the accompanying drawings.

Example 1 In FIG. 1 (A), one side of a floor material 1 having a length of about 1,800 mm and a width of about 450 mm, which is configured by laminating a decorative board 11 such as painted hard wood on the upper surface of a plywood 12. A female part 1a is formed on the side surface of the, and a projecting piece 1b is provided below the female part 1a. The projecting pieces 1b are screwed to the joist steel 4 provided on the base material at a predetermined interval by screw screws 5, and the floor material 1 is fixed to the joist steel 4 by the screw stop.

On the other hand, on the side surface on the left side of the figure of the flooring 2 in which a decorative board 21 such as hard wood, which is also painted on the upper surface of the plywood 22, is attached,
The floor material 1 is provided with a recess 2a corresponding to the protrusion 1b. An elastic fitting member 3 made of an elastic material is fixed to the side surface of the floor material.

As shown in FIG. 2, the elastic fitting member 3 includes a base body 3a, a locking piece 3b having an L-shaped cross section, which is provided below the base body 3a, and a base body.
