Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to, for example, a direct-adhesive floor member that is directly adhered to a concrete floor or the like with an adhesive or the like.
The present invention relates to a direct-adhesion floor member in which the size of a synthetic resin sheet on the back surface can be easily adjusted with a base material, and a gap between the synthetic resin sheet and the base material is less likely to occur during bonding.

[Conventional technology]

2. Description of the Related Art Conventionally, as a floor member for direct attachment, there is one in which a synthetic resin sheet is attached to the back surface of a base material group to be joined to each other by actual joining or the like for the purpose of moisture proofing, sound proofing, cushioning and the like.

This direct-adhesion floor member is formed by forming an actual groove and an actual groove on the end surface of the base material and joining the base materials together, while preliminarily cutting the same shape and size as the joined base material group. The synthetic resin sheet is prepared, and the sheet is attached to the joined base material group.

[Problems to be solved by the device]

In this conventional direct-adhesion floor member, it is difficult to dimension the base material group and the synthetic resin sheet in the manufacturing process, and the base material group and the synthetic resin sheet are easily misaligned. When the above occurs, the synthetic resin sheet protrudes from the side surface of the direct-adhesion floor member, and the end portions of the protruding synthetic resin sheet that are adjacent to each other after the laying interfere with each other to form a uniform floor surface. There was a problem that it was difficult to do.

The present invention has been made in consideration of the above circumstances, and it is easy to dimension the synthetic resin sheet on the back surface with the base material, and when the synthetic resin sheet and the base material are joined, they can be easily bonded to each other. An object of the present invention is to provide a direct-adhesion floor member in which displacement is unlikely to occur.

[Means for Solving the Problems]

The floor member for direct attachment according to the present invention is, for example, as shown in FIG. 1 to FIG. It is premised on a direct-adhesion floor member in which a heat-fusible synthetic resin sheet 20 is adhered to the back surface, and the following technical means have been taken to achieve the above object. .

After being attached to each base material 1 as a synthetic resin partial sheet 2 cut into a shape and size corresponding to each base material 1, each base material 1 to which the partial sheet 2 is attached is bonded to each other, and then each It is characterized in that the partial sheets 2 adjacent to each other at the joining line of the base material 1 are heat-sealed to be integrated with each other by the thinned synthetic resin sheet 20 at the portion corresponding to the joining line.

[Action]

In the floor member for direct attachment of the present invention, since the synthetic resin sheet is cut into the shape and size corresponding to each base material, each partial sheet is cut without being affected by the dimensional error generated when combining the base materials. It can be cut into a shape and size corresponding to the base material, and it is easy to match the dimensions of the synthetic resin sheet on the back surface with the base material, and there is a gap between the synthetic resin sheet and the base material when they are joined. It will be difficult.

〔Example〕

Hereinafter, a floor member for direct attachment according to an embodiment of the present invention will be described in detail with reference to the drawings.

The floor member is an assembly 10 in which a large number of substrates 1 are joined together by actual joining, and a synthetic resin sheet 20 attached to the back surface of the assembly 10.
And is made by, for example, the procedure shown in FIG.

That is, first, each synthetic resin partial sheet 2 cut according to the shape and size of each base material 1 is attached to the back surface of the corresponding base material 1 by a known method (S1). Actual and actual grooves are formed on the end surface of the material 1 (S2).

The partial sheet 2 may be sponge-like or may have no internal void, and an appropriate material is selected according to the application.

Then, after the base materials 1 to which the partial sheets 2 are attached are joined to each other by actual joining (S3), the adjacent partial sheets 2 are connected to each other by using, for example, a high frequency fusion machine. Fusing at the joining line (shown by the broken line in FIG. 1) (S
Four). Incidentally, the hatched portion in FIG. 1 shows the portion of the partial sheet 2 which is melted during fusion. By fusing the partial sheets 2, an integrated synthetic resin sheet 20 is formed, and the floor member shown in FIGS. 1 and 2 is obtained.

In the floor member thus obtained, a synthetic resin sheet
Since 20 is cut into the partial sheets 2 having the shape and size corresponding to each base material 1, as compared with the case where the synthetic resin sheet 20 is cut in accordance with the large assembly 10, by joining the respective base materials 1. It is possible to accurately cut the partial sheet 2 into a shape and size corresponding to each base material 1 without being affected by a dimensional error that occurs, and when the partial sheet 2 and the base material 1 are joined, there is a deviation between them. It is hard to occur. As a result, it is possible to easily obtain a non-defective product in which the synthetic resin sheet 20 and the aggregate 10 are not displaced.

Further, since the synthetic resin sheet 20 and the assembly 10 are not displaced, the end portion of the synthetic resin sheet does not project from the side surface of the direct-adhesion floor member, so that the dimensional accuracy of the direct-adhesion floor member is increased and the laying is performed. It is possible to prevent the adjacent direct-adhesion floor members from interfering with each other at the time of work, and to form a uniform floor surface.

[Effect of device]

As described above, according to the present invention, after the partial sheets are accurately and easily sized and adhered to the base material, and then the partial sheets are joined together, an assembly of the synthetic resin sheet and the base material is formed. It is possible to easily obtain a non-defective product with no dimensional error or bonding error. Then, by eliminating the dimensional error and the bonding error between the synthetic resin sheet and the aggregate of the base material in this way, the end portion of the synthetic resin sheet does not project from the side surface of the floor member for direct bonding, so that at the time of laying work Interference between the adjacent direct-adhesion floor members is prevented, and a uniform floor surface can be formed.
