As shown in FIG. 4A and FIG. 4B, the ceiling material 50 includes a ceiling material main body 500 and a third adhesive 550 provided on the peripheral end portion 500 a of the ceiling material main body 500. . For example, the first ceiling material 51 includes a ceiling material body 510 and a third adhesive 550 provided on the peripheral end portion 510 a of the ceiling material body 510. The second ceiling member 52 includes a ceiling member body 520 and a third adhesive 550 provided on the peripheral end 520a of the ceiling member body 520.

  The ceiling material main body 500 includes a base material 501 and a connection member 502 provided at a peripheral end 501a of the base material 501. For example, the connection member 502 is provided along the entire peripheral end portion 501a of the base material 501. The connection member 502 includes a first receiving part 502a and a second receiving part 502b. The first receiving portion 502 a is a concave portion that is recessed in the front-rear direction or the left-right direction, and fits with the peripheral end portion 501 a of the base material 501. The second receiving portion 502b is a concave portion that is recessed upward, and fits with the upper end portion 30c of the wall member 30 and the upper end portion of the frame 40 (for example, the upper end portion 402b of the second joiner 402).

  The third adhesive 550 is provided at the peripheral end portion 500 a of the ceiling material body 500. In this example, the third adhesive 550 is provided on the upper surface of the second receiving portion 502b. For example, the second adhesive 450 is continuously provided on the entire upper surface of the second receiving portion 502b along the peripheral end portion 500a of the ceiling material body 500. The third adhesive 550 is provided so as to be positioned between the ceiling material body 500 and the wall material 30 and between the ceiling material body 500 and the frame 40 when assembling the water unit room 10.

  In this example, a part of the third adhesive 550 of the first ceiling member 51 and a part of the third adhesive 550 of the second ceiling member 52 are connected to the ceiling member body 510 of the first ceiling member 51. The second ceiling material 52 is provided so as to be positioned between the ceiling material main body 520.

The gap between the ceiling material body 510 of the first ceiling material 51 and the ceiling material body 520 of the second ceiling material 52 is closed and watertight by the third adhesive 550.

  In this example, the third pressure-sensitive adhesive 550 is provided on the ceiling member 50, but the third pressure-sensitive adhesive 550 is provided as necessary and can be omitted. When the 3rd adhesive 550 is not provided in the ceiling material 50, other watertight members, such as packing, may be provided in the ceiling material 50, for example.

Hereinafter, the adhesive will be described.
The 1st adhesive 250, the 2nd adhesive 450, and the 3rd adhesive 550 have adhesiveness. “Adhesion” is a phenomenon commonly observed in high-viscosity liquids. It is a phenomenon that does not cause a change in state and adheres only by applying a slight pressure for a short time, thereby closing or filling the gap (exhibiting sealing properties). . In other words, the adhesiveness is pressure-sensitive adhesiveness. In other words, the pressure-sensitive adhesive is a pressure-sensitive adhesive. Note that the pressure-sensitive adhesive is, for example, a material that does not completely dry even when time passes, and always has adhesiveness. This is completely different from a so-called adhesive whose adhesiveness approaches zero as much as possible.

  The first adhesive 250, the second adhesive 450, and the third adhesive 550 have elasticity. The fact that the first pressure-sensitive adhesive 250, the second pressure-sensitive adhesive 450, and the third pressure-sensitive adhesive 550 have elasticity means that the compression set of the first pressure-sensitive adhesive 250, the second pressure-sensitive adhesive 450, and the third pressure-sensitive adhesive 550 is reduced. For example, it indicates 20% or less (JIS K 6254: 2016). The compression set of the first pressure-sensitive adhesive 250, the compression set of the second pressure-sensitive adhesive 450, and the compression set of the third pressure-sensitive adhesive 550 may be the same as or different from each other. Since the first adhesive 250, the second adhesive 450, and the third adhesive 550 have elasticity, the floor material 20 and the wall material 30, the wall materials 30 each other, the wall material 30 and the ceiling material 50, respectively. Even if the wall material 30 is removed while being connected via an adhesive, the adhesive is restored to its original shape (position) by this elasticity, so that the wall material 30 is pasted to each adhesive again. Is possible.

  In the present specification, “compression set” is a value obtained by the following method, for example. A sample formed into a cylindrical shape having a diameter of 27 mm and a thickness of 20 mm is prepared, and this sample is allowed to stand at room temperature (about 20 ° C.) for 24 hours in a state compressed to a thickness of 50% (10 mm). Thereafter, the compression is released and the sample is allowed to stand at room temperature for 24 hours, and the thickness dimension of the sample is measured. The rate of change in dimension in the thickness direction of the sample can be determined as compression set.

  The first adhesive 250, the second adhesive 450, and the third adhesive 550 can be detachably attached to the wall member 30 (at least one of the plurality of wall members 30). In other words, the first pressure-sensitive adhesive 250, the second pressure-sensitive adhesive 450, and the third pressure-sensitive adhesive 550 can be adhered to the wall material 30 and can be peeled off from the wall material 30. The first adhesive 250, the second adhesive 450, and the third adhesive 550 can be adhered to the wall material 30 again after being peeled from the wall material 30. Thereby, when assembling the water unit room 10, the wall material 30 can be repeatedly attached to and detached from the floor material 20 and the frame 40. Moreover, after attaching the ceiling material 50, the ceiling material 50 can be removed and the position of the wall material 30 can also be adjusted. By these, workability can be improved.

  In the present specification, “peelable” means that the adhesive interface is brought into close contact with the base material (for example, the wall material 30) without causing cohesive failure of the base material and the adhesive. It shows that the adhesive material can be easily peeled off. In other words, the first pressure-sensitive adhesive 250, the second pressure-sensitive adhesive 450, and the third pressure-sensitive adhesive 550 have ease of peeling. In other words, the 1st adhesive 250, the 2nd adhesive 450, and the 3rd adhesive 550 have disassembly property.

  The second adhesive 450 can be detachably attached to the first adhesive 250. In other words, the first pressure-sensitive adhesive 250 and the second pressure-sensitive adhesive 450 can stick to each other and can be peeled off. Thereby, when assembling the water unit room 10, it is possible to repeatedly attach and remove the frame 40 to the flooring 20. The third adhesive 550 can be detachably attached to the second adhesive 450. In other words, the second pressure-sensitive adhesive 450 and the third pressure-sensitive adhesive 550 can stick to each other and can be peeled off. Thereby, when the water unit room 10 is assembled, the ceiling material 50 can be repeatedly attached to and detached from the frame 40. By these, workability can be improved.

  The first adhesive 250, the second adhesive 450, and the third adhesive 550 are, for example, elastic hot melts. By using the elastic hot melt as an adhesive, the elastic hot melt is heated to a high temperature at the factory, applied to the member, and then cooled to form a shape. Can be connected. That is, the members can be connected to each other by the adhesive at the site while suppressing the shape change of the adhesive during the site or transportation to the site. Thereby, while being able to ensure watertightness easily on the site, workability can be improved.

  The first pressure-sensitive adhesive 250, the second pressure-sensitive adhesive 450, and the third pressure-sensitive adhesive 550 may be, for example, gels (gel-like substances) having adhesiveness and elasticity defined in the present invention. The composition of the first pressure-sensitive adhesive 250, the composition of the second pressure-sensitive adhesive 450, and the composition of the third pressure-sensitive adhesive 550 may be the same as or different from each other.

7 is a cross-sectional view taken along line BB shown in FIG.
As shown in FIG. 7, in a state where the wall material 30 is attached on the floor material 20, the first adhesive 250 provided on the floor material 20 adheres to the lower end portion 30 a of the wall material 30. With the first adhesive 250, the gap between the flooring main body 200 and the wall material 30 is closed and watertight. The lower end portion 30a of the wall member 30 is not limited to the lower surface of the wall member 30 and includes, for example, the surface of the wall member 30 in an area within 30 mm above the lower surface of the wall member 30. Further, for example, the lower end portion 30a of the wall member 30 is a portion where the wall member 30 is recessed downward (as shown in FIG. 7) and the wall member 30 is placed. The surface of the wall member 30 in the region in the wall mounting recess 202 when it is installed in () is also included.

  For example, the first adhesive 250 adheres to both the two wall members 30 (for example, the first wall member 31 and the second wall member 32) connected via the frame 40 (for example, the first frame 41). . In other words, the first adhesive 250 adheres to the lower end portion of the first wall member 31 and adheres to the lower end portion of the second wall member 32. Thus, when the first wall material 31 is peeled off, the fact that the first pressure-sensitive adhesive 250 is peeled off from the floor material body 200 together with the first wall material 31 between the second wall material 32 and the first pressure-sensitive adhesive 250. It can suppress by adhesive force and the adhesive force of the flooring main body 200 and the 1st adhesive 250. FIG. In addition, when the second wall member 32 is peeled off, the first adhesive member 250 is peeled off from the floor material body 200 together with the second wall member 32. It can be suppressed by the force and the adhesive force between the flooring main body 200 and the first adhesive 250. That is, when the wall material 30 is peeled off, the first adhesive 250 can be left on the flooring 20. Thereby, the attachment and detachment of the wall material 30 to the floor material 20 can be performed more easily, and the workability can be further improved while the water-tightness can be easily secured at the site.

  Further, for example, the area obtained by combining the adhesive area between the first adhesive 250 and the floor material body 200 and the adhesive area between the first adhesive 250 and the first wall material 31 is the first adhesive 250 and the second wall. It is larger than the adhesion area with the material 32. In other words, the adhesive area is a contact area between the adhesive and each member. As a result, the adhesive strength obtained by combining the adhesive strength of the first adhesive 250 with respect to the floor material body 200 and the adhesive strength of the first adhesive 250 with respect to the first wall material 31 is set to the second wall material 32 of the first adhesive 250. It can be made larger than the adhesive strength against. Therefore, when the second wall material 32 is peeled off, it is possible to further suppress the first adhesive 250 from being peeled from the floor material body 200 together with the second wall material 32.

  Further, for example, the area obtained by combining the adhesive area between the first adhesive 250 and the floor material body 200 and the adhesive area between the first adhesive 250 and the second wall member 32 is the first adhesive 250 and the first wall. It is larger than the adhesion area with the material 31.

In other words, the second adhesive 450 adheres to the side end portion of the first wall member 31 and adheres to the side end portion of the second wall member 32. Thus, when the first wall material 31 is peeled off, the second adhesive 450 is peeled off from the frame main body 400 together with the first wall material 31, and the adhesion between the second wall material 32 and the second adhesive 450. This can be suppressed by the force and the adhesive force between the frame body 400 and the second adhesive 450. In addition, when the second wall member 32 is peeled off, the adhesive force between the first wall member 31 and the second adhesive 450 indicates that the second adhesive 450 is peeled off from the frame body 400 together with the second wall member 32. And, it can be suppressed by the adhesive force between the frame body 400 and the second adhesive 450. That is, the second adhesive 450 can be left on the frame 40 when the wall material 30 is peeled off.
