Description

TECHNICAL FIELD The present invention relates to a floor sheet to be attached to the upper surface of a floor structure body of a bathroom, and further to a method of attaching the floor sheet and a method of manufacturing the floor sheet.

As disclosed in Patent Document 1, there has been developed a bathroom washing space configured by attaching a floor sheet to the upper surface of a floor structure body.
In order to attach the floor sheet efficiently, the floor sheet is pre-manufactured at the factory by laminating an adhesive layer on the back side and a release paper covering the adhesive layer. A sticking method is used.

JP 2009-138436 A

However, if the floor sheet is applied all over the floor structure body at once, air will enter between the top surface of the floor structure body and the floor sheet, causing the floor sheet to partially float and cause the floor sheet to come off. there were.

The present invention has been made to solve the above problems, and one aspect of the present invention is to provide first and second sides spaced apart and opposed in the X-axis direction and spaced-apart opposed sides in the Y-axis direction orthogonal to the X-axis direction. A floor sheet having third and fourth sides that overlap each other, and having an adhesive layer and a release paper covering the adhesive layer laminated on the back surface to be adhered to the floor structure body of the bathroom, wherein the release paper is It is divided and has a plurality of areas corresponding to the divided release paper, the plurality of areas being arranged near the first side and having openings corresponding to the drain ports of the floor structure main body. Y-axis direction adjacent areas adjacent to the specific area on both sides in the Y-axis direction, and adjacent to the specific area on the second side that is one side in the X-axis direction and an X-axis adjacent section.
According to the above configuration, since the floor sheet can be affixed so that air does not enter into each divided area, it is possible to reliably prevent the floor sheet from peeling off. In addition, since a plurality of areas are arranged around a specific area corresponding to the drain, it is possible to attach the floor sheet so that the attachment area expands from the specific area after positioning the floor sheet with respect to the drain. The sticking work can be performed smoothly and reliably.

Preferably, said plurality of sections further comprises an additional X-axis section adjacent said X-axis adjacent section and located between said X-axis adjacent section and said second side.
Preferably, the plurality of sections further includes additional Y-axis sections adjacent to the Y-axis adjacent sections on both sides and arranged between the Y-axis adjacent sections and the third and fourth sides. have
More preferably, the Y-axis additional sections extend along the third and fourth sides, respectively, and are also adjacent to the X-axis adjacent section and the X-axis additional section.
According to the above configuration, the floor sheet can be attached to the floor structure body more reliably as the number of areas increases.

Preferably, the plurality of areas further includes another X-axis direction adjacent area adjacent to the specific area on the other side in the X-axis direction, and the other X-axis direction adjacent area is the floor structure body. is attached to the side of the rising portion on the bathtub side.

A substantially rectangular peripheral edge of the floor sheet 20 has two long sides, that is, a first side 21 and a second side 22, which extend in the Y-axis direction while being spaced apart in the X-axis direction and facing each other in the Y-axis direction. It has two short sides extending in the X-axis direction, ie, a third side 23 and a fourth side 24 . The opening 25 is formed near the center of the first side 21 on the bathtub side.

The plurality of areas of the floor sheet 20 include a first area R1 (specific area) in which openings 25 are formed, and two second areas R2 (Y-axis direction adjacent areas; Y-axis direction division area), and a third area R3 (X-axis direction adjacent area; X-axis direction division area), and a fourth area R4 (X-axis direction addition area; X-axis direction division area) adjacent to the third area R3 and arranged between the third area R3 and the second side 22 including.

Furthermore, the plurality of areas of the floor sheet 20 are adjacent to the second area R2, the third area R3, and the fourth area R4 and are arranged between these areas R2 to R4 and the third side 23 and the fourth side 24, respectively. The fifth section R5 (Y-axis direction additional section; Y-axis direction division section) is adjacent to the first section R1 and the second section R2 and is arranged between these sections R1 and R2 and the first side 21. and a sixth section R6 (X-axis direction adjacent section; X-axis direction division section).

In this embodiment, the floor sheet 20 also has a narrowed area along the periphery. This peripheral region includes a region R6' extending along the first side 21 and adjacent to the sixth region R6, a region R4' extending along the second side 22 and adjacent to the fourth region R4, and a third side. 23, each having a section R5' extending along the fourth side 24 and adjacent to the fifth section R5.

In the floor sheet 20 shown in FIG. 4(A), the release paper 35 of the peripheral areas R4', R5', R6' is peeled off, and a watertight packing 40 having adhesive layers on both sides is attached to the adhesive layer 33 thereof. (See FIG. 4(B)). The watertight packing 40 is covered with release paper 45 .
Note that in the present embodiment, the double-sided adhesive film 30 and the release paper 35 are removed from the peripheral region Ra of the opening 25 .

A method of attaching the floor sheet 20 configured as described above will be described in detail.
As a preparatory step, as shown in FIG. 1, the frame member 16y of the drainage unit 16 is fixed to the peripheral area Ra of the opening 25 of the floor sheet 20 via the watertight packing 18 having adhesive layers on both sides.
