Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a wall-side mounting structure for a floor finishing material, in particular, a wooden direct-bonding floor material that is adhered to a floor substrate of a concrete house or the like.

[Conventional technology and its problems] Conventionally, in a floor of a concrete house or the like, which is directly adhered to the base without arranging floor joists, for example, a foamed polyethylene sheet or a foamed synthetic rubber is attached to the back surface of a wooden floorboard. There is a sheet that is lined to absorb the irregularities of the base.

This floor material is easy to install because the foamed synthetic resin sheet side is simply bonded and fixed to the substrate, and the floor board is elastically supported by the foamed sheet, so the impact force on the floor surface is alleviated. There are advantages.

On the other hand, in recent years, the noise caused by the floor impact sound on the downstairs has become a problem in concrete houses where such direct-adhesive floor materials are often used. Measures are being taken to reduce the sound transmitted downstairs by increasing the absorption and relaxation of.

However, the above foamed sheet has a problem that if the thickness is increased, the thickness tends to decrease due to weighting.

Therefore, as shown in FIGS. 4 and 5, the foamed synthetic resin sheet b is provided on the floor surface of the directly-applied flooring material near the wall on which furniture is placed, or near the door where weight is frequently applied by walking. It is often practiced to remove a part of the above and insert a joist material c (referred to as a joist) made of thin plywood or the like under the floor board a.

In the construction at such a portion, it is necessary to partially peel the foamed synthetic resin sheet b from the lower surface of the wooden floor board a, and the soft foamed synthetic resin sheet is partially torn by pulling at the time of peeling. However, it was left behind on the floor plate a and it was difficult to peel it off cleanly, and the work efficiency was lowered.

Further, when the peeling surface is fixed to a floor joist such as a wall by adhesion or the like, if the foamed synthetic resin sheet b is partially adhered, unevenness occurs or the adhesiveness to the joist is poor. Then, there is a problem that peeling is likely to occur.

[Purpose of the Invention] The present invention prevents the difficulty of peeling the foamed synthetic resin sheet of such a direct-adhesion floor material and the deterioration of the adhesion between the floor plate and the joist after the peeling. , The foamed synthetic resin sheet can be easily and neatly stripped off, resulting in good construction efficiency on the side of a wall, and the stripped surface is covered with the peeled fibrous thin sheet so that partial unevenness does not occur It is an object of the present invention to provide a wall-side mounting structure for a directly-applied flooring material in which unevenness does not appear on the floor finish surface in close contact with the thick joist.

[Means for Achieving the Purpose] In order to solve the above problems and achieve the object, the present invention has a thick joist on the floor base surface near the wall, and a fibrous thin sheet is provided on the lower surface of the wooden floorboard. A direct-adhesive floor material obtained by adhering and integrating a foamed synthetic resin sheet is attached to the joist upper surface when the foamed synthetic resin sheet is removed by delamination of the thin fibrous sheet on the lower surface of the end portion. It is a feature.

[Operation] The wall-mounted structure of the direct-adhesive flooring according to the present invention is integrated by interposing a fibrous thin sheet such as a pulp sheet that causes delamination in the middle layer between the bottom surface of the floorboard and the foamed synthetic resin sheet. Since the foamed synthetic resin sheet can be peeled off smoothly by utilizing the delamination of the middle layer of the thin fiber sheet, the foamed synthetic resin sheet can be peeled off neatly without tearing or remaining on the bottom surface of the floorboard. it can.

As a result, the work of stripping the foamed synthetic resin sheet near the wall can be done quickly and the construction time can be shortened.Because it can be fixed in close contact with the floor joist upper surface near the wall, unevenness such as lifting and peeling of adhesion failure can be achieved. The finish of the floor surface will be beautiful without any occurrence.

[Structure of the Invention] The invention will be described in detail below with reference to examples. FIG. 1 shows a direct-adhesive flooring material A of the invention, which has a thickness of 60 μ on the lower surface of a wooden floorboard 1 made of plywood or the like. The fibrous thin sheet 2 made of the above is adhered, and the foamed synthetic resin sheet 3 having a thickness of 2 to 10 mm is adhered integrally with the lower surface of the fibrous thin sheet.

The thin fibrous sheet 2 is not particularly limited in fiber thickness and material as long as it can be delaminated in the middle layer of the sheet 2. In short, the peel strength of the thin fibrous sheet 3 depends on the wooden floorboard 1
And the thin fibrous sheet 2, the bonding interface between the thin fibrous sheet 2 and the foamed synthetic resin sheet 3, and the foamed synthetic resin sheet 3
The fibrous thin sheet, which has a peel strength smaller than the internal peel strength and remains on the lower surface of the floorboard at the peeling surface, should not cause a step or a lift when applied on the upper surface of the thick joist 5.

Next, a case where the above directly-adhered flooring material A is installed near a wall will be described with reference to FIGS. 2 and 3.

First, a joist 5 having the same thickness as the foamed synthetic resin sheet 3 of the floor material A directly attached to the floor base surface 4 near the wall is fixed with a concrete nail or an adhesive.

Next, a cut is made in the foamed synthetic resin sheet 3 from the lower surface of the end portion of the directly attached floor material A to a position having a width equal to the width of the joist 5 so that the foamed synthetic resin sheet 3a corresponding to the joist is made of a fibrous material. The thin sheet 2 is peeled off from the middle layer portion using delamination.

At this time, the foamed synthetic resin sheet is formed on the lower surface of the wooden floorboard 1,
The floor board 1 is peeled off evenly with about half the thickness of the thin fibrous sheet 2 remaining on the upper surface of the foamed synthetic resin sheet 3.
The foamed synthetic resin sheet 3 does not remain on the lower surface of the sheet and is uniformly removed, and the peeling surface of the lower surface of the floor plate after peeling is covered with the thin fibrous sheet to prevent partial unevenness.

After the foamed synthetic resin sheet is peeled off in this manner, the lower surface of the direct-adhesion floor material A is placed on the outer joist 5 with the sheet peeling portion 6, and the sheet is adhered and fixed to the floor base to be installed on the floor surface near the wall.

At this time, the lower surface of the floor plate of the stripping portion 6 is a thin fiber sheet 2
Delamination in the middle layer portion does not cause unevenness in a part, so that a smooth floor surface can be finished without sticking to the upper surface of the joist and causing no floating or gap.

Further, since the rest of the thin fibrous sheet 2 is evenly adhered to the lower surface of the floor plate at the stripped portion, the adhesive spreads well and the adhesiveness is good at this portion.

[Effects] As described above, the direct-applying flooring material according to the present invention smoothly peels the foamed synthetic resin sheet by utilizing the delamination of the middle layer portion of the fibrous thin sheet when a thick joist is provided near the wall. In addition to shortening the construction time at the edge of the wall, the wooden floorboard can be firmly attached to the top of the joist at the edge of the wall, so there is no unevenness such as floating around the floor or peeling due to defective adhesion. It has the effect that the surface finish becomes beautiful.
