Description

  An aspect of the present invention relates to a washroom floor of a bathroom having a foam resin insulation.

  Generally, in order to improve the drainage performance of the washing floor, the surface of the washing floor is provided with a drainage slope which is inclined downward to the drainage port so that it does not take time until the washing floor is dried.

  For example, in Unexamined-Japanese-Patent No. 2006-144299 (following, patent document 1), the floor structure of the bathroom which inclines on a floor material and is forming the drainage gradient is known.

  In the structure of Patent Document 1, a slope is generally formed on a floor material which is a relatively soft resin member, and the floor material is not uniform in thickness and located near the floor surface. Being placed in the bathroom, when load is applied to the washroom floor of the bathroom, the floor material is susceptible to the load and the variation in the thickness of the floor material may cause a difference in the amount of compression for the load and affect the treading comfort. There is.

  Therefore, in order to lessen the sense of incongruity which the inventor gives to the tread feeling of the washing floor, in the general structure of the washing floor, between the floor material and the supporting material side supporting the floor structure for securing the heat insulating performance of the washing floor. It has been conceived to provide a slope for forming a drainage slope in the relatively rigid heat insulating material provided in the.

Unexamined-Japanese-Patent No. 2006-144299

  However, in the bathroom floor, if the heat insulating material is simply provided with a slope in order to provide a drainage gradient, there may be a location where the thickness of the heat insulating material is reduced, which may affect the heat insulating performance. Therefore, it is necessary to increase the thickness of the entire heat insulating material, but if the thickness of the entire heat insulating material is increased, there is a problem that the cost is increased accordingly.

  The present invention has been made based on the recognition of such problems, and it is possible to suppress the cost even in the case where the thickness is increased in order to form the drainage gradient while reducing the influence on the step comfort. The aim is to provide a washable floor for the bathroom.

  According to the present invention configured to achieve the above object, there is provided a washing floor of a bathroom provided on the surface of the washing floor and having a drainage gradient inclined toward the drainage port, wherein the drainage port from the end of the washing floor A heat insulating material made of foamed resin to which a drainage gradient is given, and a flat floor supporting surface supported in a slidable state from below by mounting the heat insulating material; A floor material provided on the heat insulating material, wherein the heat insulating material is provided with a plurality of notches cut from the support material side toward the floor material, It is characterized in that the depth of the notch is formed to be deeper from the side of the drainage port to the side of the end.

According to the washing floor of this bathroom, a slope is provided to provide a drainage gradient to the highly rigid heat insulating material which is located on the support side supporting the washing floor from the surface of the washing floor. As the thickness of the heat insulating material is increased while suppressing the uncomfortable feeling of the step in the place, by providing the notches in the heat insulating material, the material cost required for the heat insulating material can be reduced while maintaining the heat insulating performance.
Therefore, coexistence with cost reduction is attained, suppressing the sense of incongruity given to the treading feeling at the time of stepping on the washing floor.

  In the present invention, preferably, in the plurality of notches, the thickness from the upper surface of the heat insulating material to the upper surface of the notches gradually increases from the drain side toward the end. It is formed.

According to the washing floor of this bathroom, in the plurality of notches, the thickness from the upper surface of the heat insulating material to the upper surface of the notches is formed so as to gradually increase from the drain side to the end side Therefore, by providing notches for the heat insulating material that is located on the side of the support that supports the washing floor from the surface of the washing floor and has excellent rigidity, the tread comfort due to the difference in the amount of compression for the load that may be generated slightly It becomes possible to suppress the sense of discomfort.
Specifically, since the heat insulating material and the support material are slidably fixed, when a load is applied to the washing floor, the deeper the notch, the more the deflection according to the depth of the notch. It occurs and the lower surface of the notch spreads out. Therefore, according to this configuration, the amount of compression with respect to the load increases from the outlet side toward the end side. On the other hand, as the thickness from the upper surface of the heat insulating material to the upper surface of the notch is larger, the upper surface of the notch is less likely to warp downward. Therefore, according to this configuration, the amount of compression with respect to the load decreases from the outlet side toward the end side.
Therefore, even if the depth of the notch is increased from the drainage port side toward the end side, the amount of compression of the heat insulating material due to the load can be made constant, and the uncomfortable feeling given to the tread feeling can be further suppressed.

  In the present invention, preferably, the notch is formed in a planar shape so that the upper portion thereof is warped downward when a downward load is applied to the upper surface of the heat insulating material.

According to the washing floor of this bathroom, the upper portion of the notch receives the load not on the surface but on the surface, for the load applied to the upper surface of the heat insulating material, thus leading to receiving the load in a wide cross-sectional area In addition, since there is a space below the surface, the upper portion of the notch is easily bent downward by the area of the upper surface of the notch.
Therefore, even if the notch is provided deeper from the drainage port side to the end side, the drainage floor surface itself is drained by largely changing the thickness from the upper surface of the heat insulating material to the upper surface of the notch in the plurality of notches. It is possible to control the amount of compression without increasing the gradient. From the above, it is possible to further suppress the uncomfortable feeling given to the stepping feeling without increasing the drainage slope of the washing floor itself.

  In the present invention, preferably, the area of the upper surface of the plurality of notches is formed so as to gradually decrease from the outlet side toward the end.

According to the washing floor of this bathroom, since the area of the upper surface of the plurality of notches is formed so as to gradually decrease from the drainage side toward the end side, the support that supports the washing floor from the surface of the washing floor By providing the notches with the heat insulating material located on the material side and having excellent rigidity, it is possible to suppress the uncomfortable feeling to the treading comfort due to the difference in the amount of compression with respect to the load that may be generated slightly.
Specifically, since the heat insulating material and the support material are slidably fixed, when a load is applied to the washing floor, the deeper the notch, the more the deflection according to the depth of the notch. It occurs and the lower surface of the notch spreads out. Therefore, according to this configuration, the amount of compression with respect to the load increases from the outlet side toward the end side. On the other hand, as the area of the upper surface of the notch is smaller, the upper surface of the notch is less likely to warp downward. Therefore, according to this configuration, the amount of compression with respect to the load decreases from the outlet side toward the end side.
Therefore, even if the depth of the notch is increased from the drainage port side toward the end side, the amount of compression of the heat insulating material due to the load can be made constant, and the uncomfortable feeling given to the tread feeling can be further suppressed.

  In the present invention, preferably, the area of the lower surface of the plurality of notches is formed so as to gradually decrease from the outlet side toward the end.

According to the washing floor of this bathroom, since the area of the lower surface of the plurality of notches is formed so as to gradually decrease from the drainage side to the end side, the support that supports the washing floor from the surface of the washing floor By providing the notches with the heat insulating material located on the material side and having excellent rigidity, it is possible to suppress the uncomfortable feeling to the treading comfort due to the difference in the amount of compression with respect to the load that may be generated slightly.
Specifically, since the heat insulating material and the support material are slidably fixed, when a load is applied to the washing floor, the deeper the notch, the more the deflection according to the depth of the notch. It occurs and the lower surface of the notch spreads out. Therefore, according to this configuration, the amount of compression with respect to the load increases from the outlet side toward the end side. On the other hand, the smaller the area of the lower surface of the notch, the smaller the amount of spread of the lower surface of the notch. Therefore, according to this configuration, the amount of compression with respect to the load decreases from the outlet side toward the end side.
Therefore, even if the depth of the notch is increased from the drainage port side toward the end side, the compression amount of the heat insulating material due to the load can be made constant, and the uncomfortable feeling given to the tread feeling can be suppressed.

According to the aspect of the present invention, the location of the wash floor is provided with a slope for applying a drainage gradient to the rigid heat insulating material that is located on the support side supporting the wash floor from the surface of the wash floor. As the thickness of the heat insulating material is increased while suppressing the uncomfortable feeling of the tread feeling, by providing the notches in the heat insulating material, it is possible to reduce the material cost required for the heat insulating material while maintaining the heat insulating performance.
Therefore, coexistence with cost reduction is attained, suppressing the sense of incongruity given to the treading feeling at the time of stepping on the washing floor.

Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. In the drawings, the same components are denoted by the same reference numerals and the detailed description will be appropriately omitted.
FIG. 1 is a schematic perspective view of a bathroom unit having a bathroom floor according to a first embodiment of the present invention.
FIG. 2 is a perspective view showing the structure of the washing floor of the bathroom according to the first embodiment of the present invention.

  As shown in FIG. 1, the bathroom floor 1 is disposed adjacent to the bathtub 2. Between the bathtub 2 and the washroom floor 1, a bath apron 9 is provided which serves as a partition wall that divides the washroom and the bathtub installation part.

In the washing floor 1 according to the present embodiment, the drainage pipe 5 is laid under the washing floor 1, that is, in the space between the washing floor 1 and the bathroom installation surface. The drainage pipe 5 connects the drainage port 15 provided on the washing floor 1 with a drainage pipe line outside the bathroom.

Washing floor 1 is formed into a shallow bottom (pan) shape whose peripheral edge is raised upward by providing water blocking wall 1b so as to surround each side of the peripheral edge of washing place 1a. It has a three-dimensional shape that does not leak hot water. The peripheral portion of the washing place 1a shown in FIG. 1 is substantially quadrilateral. In the description of the present embodiment, when the water blocking wall 1 b provided on the bathtub 2 side is distinguished from the other water blocking wall 1 b, it is referred to as the water blocking wall 1 b (W).

On the surface of washing place 1a ("surface" used in the following description refers to the surface inside the bathroom unless otherwise stated), so that the hot and cold water attached to the surface of washing place 1a flows to drainage port 15. A drainage slope 10 consisting of a slope having a predetermined slope toward the drainage port 15
1, 102, 103, 104 and 105 are provided. This gradient is a downward gradient directed away from each side of the outer edge of the washing place 1a. In addition, boundaries between adjacent drainage slopes are defined by drainage slopes 101, 102, 103, 104 and 10, respectively.
Similar to 5, it has a predetermined slope towards the outlet 15. The gradient of the border is the washroom 1a
It is considered to be a downward slope directed away from each side of the outer periphery of.
The drainage slope is formed in a gentle slope of about 1/20 to 1/100.

In the present embodiment, the drainage slopes 101, 105 provided on the bathtub 2 side of the washing place 1a.
Are disposed across the drain port 15 on both sides. A boundary line L between the surface of the water blocking wall 1b (W) on the bathtub 2 side of the washing place 1a and the surface of the washing place 1a exists on the same straight line. The drainage slope surfaces 101, 105 have a slope which is a downward slope away from the boundary L.

As shown in FIG. 2, the washing floor 1 according to the present embodiment includes a support 11, a heat insulating material 12, and a floor material 13 in order from the ground contact surface of the washing floor 1 to the outermost surface.
Around the heat insulating material 12 except the bathtub 2 side, a wall mounting member 7 on which wall materials of a bathroom unit (not shown) can be mounted is attached. Moreover, the standing wall part 8 is attached to the bathtub 2 side of the heat insulating material 12.

The support member 11 has a high strength support surface member 111 and four adjustable length support legs 112 provided at four corners.
The work surface is provided in the support surface material 111, and the lid | cover 113 is covered. The upper surface of the support surface material 111 in a state in which the lid 113 is covered is a floor support surface that supports the heat insulating material 12.

The heat insulating material 12 is made of a foamed resin excellent in rigidity, and is placed on the upper surface of the support material 11.
In the present embodiment, foamed polypropylene is used as the foamed resin, so that the feeling of stepping on the floor 1 of the washing place is not made uncomfortable.
Since foamed polypropylene has high impact resistance compared to other foamed resins, it can be used to provide a floor structure having an excellent strength that can withstand severe use.
In addition, as a foamed resin, a hard material which is difficult to be compressed and deformed, and a foaming ratio are preferable. For example, foamed polystyrene, foamed polyethylene, and foamed polyurethane are used.

Further, the heat insulating material 12 is formed with inclined surfaces 121a, 122a, 123a, 124a and 125a which are reference surfaces for forming the drainage slope surfaces 101, 102, 103, 104 and 105 of the washing place 1a described above. Therefore, the heat insulating material 12 has a shape in which the thickness gradually decreases from the water blocking wall 1b (end portion) of the washing place 1a toward the drainage port 15 of the washing place 1a.
The description about the detailed shape of the heat insulating material 12 is mentioned later.
The form of the drainage slope surface and the form of the inclined surface are not limited to the example shown in FIG.

  The floor material 13 is provided on the upper surface of the heat insulating material 12 and has a cushion layer 13 a and a surface layer 13 b provided on the upper surface of the cushion layer 13 a and located on the outermost surface of the washing floor 1.

The cushion layer 13 a is formed as a flat plate and mounted on the upper surface of the heat insulating material 12. The cushioning layer 13a is a soft material having elasticity to give a soft step feeling, and has a cushioning property higher than that of the heat insulating material 12. That is, the cushion layer 13 a is more easily compressed and deformed than the heat insulating material 12.
Since the cushioning layer 13a is formed on a flat plate, the degree of influence of the cushioning layer 13a on the treading comfort can be made constant regardless of the location of the washing floor 1.

  The surface layer 13 b is made of a flexible sheet material having waterproofness and flexibility. The surface layer 13b may be processed to have an uneven surface to improve drainage.

Hereinafter, the heat insulating material 12 in the first embodiment of the present invention will be described with reference to FIGS. 3 to 5.
FIG. 3 is a schematic perspective view showing a heat insulating material in the first embodiment of the present invention.
Arrow S1 shown in FIG. 3 represents the direction of the downward slope of each of the drainage slope surfaces 121a to 125a. That is, the direction in which the arrow S1 faces indicates the downward direction. Thus, the drainage gradient surfaces 121a to 125a are inclined planes that are lowered in directions orthogonal to the sides starting from each side of the outer peripheral edge of the washing floor 1.
The thickness of the heat insulating material 12 is gradually reduced so as to be gradually thinner from the water blocking wall 1 b side to the drainage port 15 side. Due to this change in thickness, a drainage gradient is applied to the surface of the floor 1 of the washing place, which is a downward slope toward the drainage port 15. That is, the slopes 121a to 125a are similar to the drainage slopes 101 to 105.

FIG. 4 is a schematic cross-sectional view of the cross section B-B shown in FIG.
As shown in FIG. 4, the heat insulating material 12 is provided with a plurality of notches 12 a from the surface placed on the support material 11 toward the floor material 13 side. The depth D (D1, D2...) Of the notch is formed to be gradually deeper from the side of the drainage port 15 toward the side of the water blocking wall 1b.
For example, when comparing D1 located on the drainage port 15 side with D2 located on the water blocking wall 1b side from D1, the depth of the notch 12a has a relationship of D1 <D2.

Further, the thickness d (d1, d2...) From the upper surface of the notch 12a to the upper surface of the heat insulating material 12 is formed so as to gradually increase from the drainage port 15 side to the water blocking wall 1b side.
For example, when comparing d1 located on the drainage port 15 side with d2 located on the water blocking wall 1b side from d1, the thickness d from the top surface of the notch 12a to the top surface of the heat insulating material 12 satisfies the relationship d1 <d2. Become.
The thickness d includes one that increases by about 0.1 mm when the thickness of the heat insulating material 12 increases by 1 mm.

FIG. 5 is a schematic view comparing the compressed state when the same load is applied to different parts of the washing floor in FIG.
As shown in FIG. 5, when a load is applied to the washing floor 1, a load is applied to the upper surface w (w1, w2...) Of the notch 12a via the heat insulating material 12.
When a load is applied to the upper surface w of the notch 12a, the upper surface w of the notch 12a bends downward, and the area (size) of the lower surface W (W1, W2,...) Of the notch 12a increases.
In addition, on the upper surface w of the notch, the portion shown by the solid line shows the state of the notch 12a before the load is applied, and the portion shown by the broken line is the notch 12a when the load is applied. The deformation state is shown.

  As shown in FIG. 5, comparing the case where the foot is placed at a position close to the drainage port 15 side of the heat insulating material 12 (load is applied) and the case where the foot is placed at a position near the water blocking wall 1b side, The upper surface w of the notch 12a is bent downward when the foot is placed at a position close to the drainage port 15 side.

In addition, when the same load is applied to the upper surfaces w of the plurality of notches 12a, when comparing the lower surfaces W1 of the notches 12a positioned on the drain 15 side with W2 positioned on the water blocking wall 1b side from W1. The area of the lower surface W of the notch 12a has a relation of W1 ≒ W2.
In the lower surface W of the notch 12a, a portion shown by a solid line shows the state of the lower surface W of the notch 12a before applying a load, and a portion shown by a broken line is a notch when a load is applied. The deformation | transformation state of the lower surface W of 12a is shown.

FIG. 6 is an explanatory view of a force received by the upper surface of the notch when a load is applied to the washing floor in FIG.
As shown in FIG. 6, the load applied to the washing floor 1 is uniformly loaded on a horizontal surface, not on a point, on the upper surface w of the notch.
The substantially horizontal surface shape does not mean that the upper surface w of the notch 12a is intentionally provided with a concavo-convex shape at a horizontal angle of 10 ° to -10 ° with respect to the ground contact surface, but includes a rough surface due to dimensional tolerance.

As described above, according to the washing floor 1 according to the first embodiment, the drainage slope is located on the side of the support 11 that supports the washing floor 1 from the surface of the washing floor 1 and the heat insulating material 12 having excellent rigidity. As the thickness of the heat insulating material 12 is thicker, the heat insulating material 12 is provided with the notches 12 a as the thickness of the heat insulating material 12 is thicker while suppressing the discomfort of the treading comfort in the place of the washing floor 1 The material cost required for the heat insulating material 12 can be reduced while maintaining it.
Therefore, coexistence with cost reduction is attained, suppressing the discomfort given to the tread feeling at the time of stepping on the washing floor 1. FIG.

Moreover, according to the washing floor 1 according to the first embodiment, the thickness from the upper surface of the heat insulating material 12 to the upper surface w of the notch 12a gradually increases from the drainage port 15 side to the water blocking wall 1b side Since the heat insulating material 12 located on the side of the support 11 supporting the wash floor 1 from the surface of the wash floor 1 and having excellent rigidity is provided with the notches 12 a, there is a risk of slight generation. It becomes possible to suppress a sense of incongruity in the feeling of stepping due to the difference in the amount of compression for a certain load.
Specifically, since the heat insulating material 12 and the support material 11 are slidably fixed, when a load is applied to the washing floor 1, the deeper the notch 12a, the depth of the notch 12a. In response to this, deflection occurs and the area of the lower surface W of the notch 12a increases. Therefore, according to this configuration, the amount of compression with respect to the load increases from the side of the drainage port 15 toward the side of the water blocking wall 1b. On the other hand, as the thickness from the upper surface of the heat insulating material 12 to the upper surface w of the notch is thicker, the upper surface w of the notch is less likely to warp downward. Therefore, according to this configuration, the amount of compression with respect to the load decreases from the side of the drainage port 15 toward the side of the water blocking wall 1b.
Therefore, even if the depth of the notch 12a is increased from the side of the drainage port 15 toward the water blocking wall 1b, the amount of compression of the heat insulating material 12 due to the load can be made constant, and the uncomfortable feeling given to the treading comfort can be suppressed. .
In other words, the influence of the depth D of the notch on the amount of compression and the effect of the thickness d from the top surface of the heat insulating material 12 to the top surface w of the notch 12a are balanced.
Therefore, even if the depth of the notch 12a is increased from the side of the drainage port 15 toward the water blocking wall 1b, the amount of compression of the heat insulating material 12 due to the load can be made constant, and the uncomfortable feeling given to the treading comfort can be suppressed. .

Furthermore, in the bathroom floor 1, the upper surface w of the notch 12 a does not receive a load at a point but leads to the load being evenly distributed on the horizontal surface, and the amount of compression It becomes possible to control.
Therefore, it is possible to suppress the uncomfortable feeling given to the stepping feeling.

Next, a heat insulating material according to a second embodiment of the present invention will be described with reference to FIG.
FIG. 7 is a schematic cross-sectional view showing a heat insulating material in the second embodiment of the present invention.
Here, in the washroom floor 1 of the bathroom according to the second embodiment of the present invention shown in FIG. 7, the same parts as those of the washroom floor 1 of the bathroom according to the first embodiment of the present invention shown in FIG. And their explanations are omitted

As shown in FIG. 7, in the washing floor 1 of the bathroom according to the second embodiment of the present invention, the shape of the notch 12 a in the heat insulating material 12 is different from that of the first embodiment.
The notch 12a is formed so that the dimension of the upper surface w of the notch becomes gradually smaller as it goes from the drainage port 15 side to the water blocking wall 1b side.
For example, when comparing w1 located on the drainage port 15 side with w2 located on the water blocking wall 1b side from w1, the upper surface w of the notch 12a has a relationship of w1> w2.
That is, as the depth of the notch 12a is deeper, the area (size) of the notch upper surface w is smaller.

As described above, according to the washing floor 1 according to the second embodiment, the area of the upper surface of the notch 12a is formed so as to gradually decrease from the drainage port 15 side to the water blocking wall 1b side. Since the heat insulating material 12 which is located on the side of the support 11 that supports the wash floor 1 from the surface of the wash floor 1 and is excellent in rigidity, the notch 12 a is provided to compress against a load that may be generated slightly. It becomes possible to suppress the sense of discomfort to the feeling of stepping due to the difference in the amount.
Specifically, since the heat insulating material 12 and the support material 11 are slidably fixed, when a load is applied to the washing floor 1, the deeper the notch 12a, the depth of the notch 12a. In response to this, deflection occurs and the dimension of the lower surface W of the notch widens. Therefore, according to this configuration, the amount of compression with respect to the load increases from the side of the drainage port 15 toward the side of the water blocking wall 1b. On the other hand, as the area of the upper surface 121a of the notch is smaller, the upper surface 121a of the notch is less likely to warp downward. Therefore, according to this configuration, the amount of compression with respect to the load decreases from the side of the drainage port 15 toward the side of the water blocking wall 1b.
Therefore, even if the depth of the notch 12a is increased from the side of the drainage port 15 toward the water blocking wall 1b, the amount of compression of the heat insulating material 12 due to the load can be made constant, and the uncomfortable feeling given to the treading comfort can be suppressed. .
In other words, the effect of the depth of the notch 12a on the amount of compression and the effect of the area of the upper surface w of the notch on the amount of compression are balanced.

Next, a heat insulating material according to a third embodiment of the present invention will be described with reference to FIG.
FIG. 8 is a schematic cross-sectional view showing a heat insulating material in the third embodiment of the present invention.
Here, in the washing floor 1 of the bathroom according to the third embodiment of the present invention shown in FIG. 8, the same parts as the washing floor 1 of the bathroom according to the first embodiment of the present invention shown in FIG. And their explanations are omitted

As shown in FIG. 8, in the bathroom floor 1 according to the third embodiment of the present invention, the shape of the notch 12 a in the heat insulating material 12 is different from that of the first embodiment.
The dimension of the lower surface of the notch 12a is formed gradually smaller as it goes from the drainage port 15 side to the water blocking wall 1b side.
For example, when comparing W1 located on the drainage port 15 side with W2 located on the water blocking wall 1b side from W1, the lower surface W of the notch has a relationship of W1> W2.
That is, the deeper the notch 12a, the smaller the area of the lower surface W of the notch 12a.

As described above, according to the washing floor 1 according to the third embodiment, the area of the lower surface of the notch 12a is formed so as to gradually decrease from the drainage port 15 side to the water blocking wall 1b side. Since the heat insulating material 12 which is located on the side of the support 11 that supports the wash floor 1 from the surface of the wash floor 1 and is excellent in rigidity, the notch 12 a is provided to compress against a load that may be generated slightly. It becomes possible to suppress the sense of discomfort to the feeling of stepping due to the difference in the amount.
Specifically, since the heat insulating material 12 and the support material 11 are slidably fixed, when a load is applied to the washing floor 1, the deeper the notch 12a, the depth of the notch 12a. In response to this, deflection occurs and the lower surface W of the notch 12a spreads. Therefore, according to this configuration, the amount of compression with respect to the load increases from the side of the drainage port 15 toward the side of the water blocking wall 1b. On the other hand, the smaller the dimension of the lower surface W of the notch 12a, the smaller the amount by which the area of the lower surface W of the notch 12a expands. Therefore, according to this configuration, the amount of compression with respect to the load decreases from the side of the drainage port 15 toward the side of the water blocking wall 1b.
Therefore, even if the depth of the notch 12a is increased from the side of the drainage port 15 toward the water blocking wall 1b, the amount of compression of the heat insulating material 12 due to the load can be made constant, and the uncomfortable feeling given to the treading comfort can be suppressed. .
In other words, the effect of the depth of the notch 12a on the amount of compression and the effect of the dimension of the lower surface W of the notch 12a on the amount of compression are balanced.

As mentioned above, although embodiment of the washing floor 1 of the bathroom which concerns on this invention was described, this invention is not limited to the specific example of these implementation.
In the present invention, in order to control the amount of compression according to the depth of the notch 12a, the parameters of the upper surface w and the lower surface W of the notch 12a provided in the heat insulating material 12 are from the drainage port 15 side to the support wall 1b side You may change at the same time.
Further, those to which a person skilled in the art has appropriately modified the design of these specific examples are also included in the scope of the present invention as long as they have the features of the present invention. For example, the elements included in the specific examples described above and their arrangements, materials, conditions, shapes, sizes, and the like are not limited to those illustrated, and can be changed as appropriate.
