  Conventionally, an airtight structure for closing a space between a bathroom unit and an inner surface of an installation space has been proposed (for example, see Patent Document 1). The airtight structure described in Patent Document 1 is configured by attaching a blocking film across the base of a building and a waterproof pan of a bathroom unit. One end of this shielding film is fixed in advance to the base of the building with a presser plate and a screw, and after installing the waterproof pan, the other end is fixed to the inner surface of the vertical portion standing on the outer periphery of the waterproof pan with a screw. The

Japanese Patent No. 3091709

  However, in the conventional airtight structure described in Patent Document 1, one end side of the blocking film is fixed to the base of the building before the installation of the waterproof pan, and the other end side of the blocking film is installed after the installation of the waterproof pan. Since it is fixed to the vertical part, the construction procedure is restricted, so it is difficult to sufficiently improve the construction efficiency. Further, in the conventional airtight structure, since the shielding film is fixed by screwing, a gap is formed between the shielding film and the base or the vertical portion, and the airtightness may not be sufficiently improved.

  The objective of this invention is providing the construction method of the airtight structure which can improve construction efficiency by favorable workability, and can improve airtightness, a bathroom unit, and a bathroom unit.

  The airtight structure of the present invention is an airtight structure in which a gap between an inner surface of an installation space and an outer surface of an installation member installed in the installation space is closed with an airtight member, and the airtight member includes a base material having elasticity. And a skin material having airtightness provided on the surface of the base material, and the airtight member is pressed into the gap so that the base material is pressed to generate a repulsive force. The skin material is brought into close contact with an inner surface of the installation space and an outer surface of the installation member by a repulsive force.

  According to the present invention as described above, an airtight member is constituted by having a base material having elasticity and an outer skin material having airtightness, and this airtight member is formed in the gap between the outer surface of the installation member and the inner surface of the installation space. The gap can be closed by bringing the skin material into close contact with the inner surface of the installation space and the outer surface of the installation member by the repulsive force of the pressed and pressed base material. According to such an airtight structure, after installing the installation member in the installation space, the airtight member may be press-fitted into the gap between the outer surface of the installation member and the inner surface of the installation space, or the outer surface of the installation member and the installation space An airtight member may be attached to either one of the inner surfaces, and the airtight member may be sandwiched between the other, and the construction procedure is not restricted.

  In addition, since the airtight member is held in the gap between the outer surface of the installation member and the inner surface of the installation space by the repulsive force of the pressed base material, fixing work by screwing or the like can be eliminated, and construction labor can be reduced. Can do. Therefore, it is possible to improve the workability because the construction procedure is not restricted and the construction labor can be reduced. Furthermore, the skin material is brought into close contact with the inner surface of the installation space and the outer surface of the installation member by the repulsive force of the pressed base material, thereby preventing a gap from being formed between each surface and the skin material.

In other words, since the elastic base material is bent, its restoring force acts in a direction to expand the airtight member, so that the close force is also exerted by the restoring force against bending in addition to the repulsive force due to the compression of the base material. Can be increased. Therefore, an airtight member can be manufactured easily and inexpensively as compared with the case where the skin material is provided on both surfaces of the base material. Further, if the airtight member is bent and press-fitted into the gap between the outer surface of the installation member and the inner surface of the installation space, the workability of the press-fit can be improved and the workability can be further improved.

  The airtight structure of the present invention is an airtight structure in which a gap between the inner surface of the installation space and the outer surface of the installation member installed in the installation space is closed with an airtight member, and the airtight member is elastic and airtight. The airtight member is pressed into the gap to generate a repulsive force, and the repulsive force causes the surface of the airtight member to be in contact with the inner surface of the installation space and the installation. It is characterized by being in close contact with the outer surface of the member.

  According to the present invention as described above, an airtight member having elasticity and airtightness is press-fitted into a gap between the outer surface of the installation member and the inner surface of the installation space, and the surface of the airtight member is brought into contact with the inner surface of the installation space by the repulsive force that is pressed. By closely contacting the outer surface of the installation member, the gap can be closed. In addition, since the airtight member is held in the gap between the outer surface of the installation member and the inner surface of the installation space by the repulsive force of the pressed airtight member, fixing work by screwing or the like can be eliminated, and construction labor can be reduced. Can do. Therefore, it is possible to improve the workability because the construction procedure is not restricted and the construction labor can be reduced. Further, the surface of the installation space is brought into close contact with the inner surface of the installation space and the outer surface of the installation member by the repulsive force of the pressed air-tight member, thereby preventing a gap from being formed between these surfaces and the air-tight member. Can improve airtightness.

  Furthermore, in the airtight structure of the present invention, an adhesive layer is provided between at least one of the inner surface of the installation space and the airtight member and between the outer surface of the installation member and the airtight member. Is preferred.

  According to such a configuration, the hermetic member can be fixed by the adhesive force of the adhesive layer in addition to the holding force for holding the hermetic member by the repulsive force of the base material. And airtightness can be maintained. At this time, the adhesive layer is, for example, a double-sided tape, and one adhesive surface of this double-sided tape is stuck on the inner surface of the installation space or the outer surface of the installation member, and the release paper on the other adhesive surface is left. The airtight member may be press-fitted, and after the press-fitting, the other release paper may be peeled off and pulled out, and the other adhesive surface and the skin material of the airtight member may be bonded. By adopting such a procedure, it is possible to easily increase the fixing strength of the airtight member without reducing the workability.

  Moreover, the bathroom unit of this invention is a bathroom unit provided with one of the said airtight structures, Comprising: The said installation member is a unit member which comprises this bathroom unit, It is characterized by the above-mentioned.

  According to such a bathroom unit of the present invention, the airtight member is held in the gap between the outer surface of the unit member and the inner surface of the installation space by the repulsive force of the pressed base material as in the above-described airtight structure. In addition, fixing work by screwing or the like can be eliminated, and construction labor can be reduced. Therefore, it is possible to improve the workability because the construction procedure is not restricted and the construction labor can be reduced. Furthermore, the skin material is brought into close contact with the inner surface of the installation space and the outer surface of the unit member by the repulsive force of the pressed base material, thereby preventing a gap from being formed between these surfaces and the skin material. Can improve airtightness.

  On the other hand, the bathroom unit construction method of the present invention is a bathroom unit construction method in which a gap between an outer surface of a unit member constituting the bathroom unit and an inner surface of an installation space in which the bathroom unit is installed is closed with an airtight member. In addition, the airtight member is configured to include an elastic base material and an airtight skin material provided on the surface of the base material, or made of a material having elasticity and airtightness. Then, after the bathroom unit is installed in the installation space, the airtight member is press-fitted into the gap, and the skin material or the surface of the airtight member is attached to the pressed base material or the repulsive force of the airtight member. The inner space of the installation space and the outer surface of the unit member are brought into close contact with each other, and the airtight member is held in the gap.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the airtight structure of the present embodiment is a gap between the bathroom unit 1 and the inner surface of the installation space S in which the bathroom unit 1 is installed (the inner surface WS of the outer wall W1 and the inner wall W2 described later). By closing G with the airtight member 10, the air flow through the gap G is blocked, thereby ensuring the heat insulating performance of the building.

  The building includes, for example, a foundation F and a foundation slab FS, a plurality of outer walls W1 and inner walls W2 supported on the upper side of the foundation F, a first floor F1, and a ceiling constructed on the upper side of the outer wall W1 and the inner wall W2 (second floor). Floor) F2. On the other hand, an underfloor space UF is formed between the foundation slab FS and the first-floor floor F1, and this underfloor space UF is connected to the outside via a vent formed between the foundation F and the outer wall W1. Under-floor ventilation that allows the outside air to flow into the under-floor space UF is formed. Moreover, the building has a heat insulating structure in which a heat insulating material is provided inside the outer wall W1 and the first floor F1, and heat transfer is suppressed between the outside and the inside of the building.

  The installation space S in which the bathroom unit 1 is installed is configured to be surrounded by a foundation F and a foundation slab FS, four outer walls W1 and inner walls W2, and a ceiling F2. The installation space S communicates with the underfloor space UF, and outside air that flows in from the outside through the vents enters the lower portion of the installation space S through the underfloor space UF. For this reason, the airtight structure of this embodiment ensures the heat insulation performance with respect to the inner wall W2 and the ceiling F2 by blocking the circulation of the outside air so that the outside air entering the lower part of the installation space S does not rise inside the installation space S. It is something to try.

  The bathroom unit 1 is supported on a bathtub 3 and a washing floor (waterproof pan) 4 supported on a foundation slab FS via a bundle 2 and the like, and a plurality of posts erected from the periphery of the bathtub 3 and the washing floor 4 Wall panel 5, ceiling panel 6 supported by a ceiling connecting beam connecting the tops of a plurality of posts, and a bathroom doorway and windows (not shown). A bathtub apron 7 is provided at the level difference between the bathtub 3 and the washing floor 4, and a side edge of the bathtub apron 7 is supported by a side vertical member 8 extending between the bathtub 3 and the washing floor 4. Therefore, the bathroom unit 1 forms a bathroom space surrounded by the bathtub 3, the washing floor 4, the wall panel 5, the ceiling panel 6, and the bathtub apron 7, and this bathroom space has a predetermined airtight performance. In addition, air is not allowed to flow between the installation space S.

  As shown in FIG. 3, the airtight member 10 includes an inner surface WS of the face material P on the installation space S side that constitutes the outer wall W <b> 1 and the inner wall W <b> 2, and an outer surface of the rising piece 9 that rises from the peripheral edge of the bathtub 3 and the washing floor 4. 9A and press-fitted between. Although not shown, the airtight member 10 is also press-fitted between the inner surface WS of the face material P and the outer surface 8A of the side vertical member 8 that supports the side edge of the bathtub apron 7. Therefore, the airtight member 10 includes the outer surfaces 8A and 9A that are continuous with the entire circumference of the bathroom lower structure (unit member) 1A including the bathtub 3, the washing floor 4, the bathtub apron 7, the side vertical member 8, and the like, and the bathroom. The gap G formed on the inner surface WS of the face material P of the outer wall W1 and the inner wall W2, which is the inner surface of the installation space S that surrounds the four circumferences of the lower structure, is provided.

  As shown in FIG. 4 (A), the airtight member 10 is made of a sheet material having an overall long shape, and is formed on a surface of one side of the base material 11 having a predetermined thickness and elasticity. The skin material 12 is airtight and is configured to be foldable so that the skin material 12 faces outward. The thickness dimension of the hermetic member 10 is set according to the size of the gap G. For example, the thickness dimension of the hermetic member 10 in a bent state with respect to the design value of the size of the gap G. Is set in a range of 1.1 times to 3.0 times. Moreover, the width dimension of the airtight member 10 is set to about 300 mm, for example.

  Although the base material 11 is comprised from the resin-made nonwoven fabric, a porous material, etc., for example, the raw material will not be specifically limited if the repulsive force is exhibited by being compressed. Although the skin material 12 is comprised from the resinous film-form material, the raw material will not be specifically limited if it has airtightness. The base material 11 and the skin material 12 may be formed separately from each other and then integrated by adhesion or the like, or may be formed by integral molding.

  As shown in FIG. 4B, the airtight member 10 is folded in two so that the skin material 12 faces outward and is press-fitted into the gap G. That is, the airtight member 10 in a folded state has a thickness dimension that is approximately twice the original dimension, and is 1.1 to 3.0 times larger than the size of the gap G (for example, 20 mm). It becomes a thickness dimension (22 mm to 60 mm). Therefore, the airtight member 10 press-fitted into the gap G is elastically deformed so that the thickness of the base member 11 is pressed and the thickness is reduced, and the inner surface WS of the outer wall W1 and the inner wall W2 and the bathroom lower structure (tub) 3 and the standing piece 9 of the washing floor 4 and the outer surfaces 8A and 9A of the side frame 8) are pushed back.

  Thus, the airtight member 10 press-fitted into the gap G is retained in the gap G by pushing back the inner surface WS of the outer wall W1 and the inner wall W2 and the outer surfaces 8A and 9A of the bathroom lower structure 1A by the repulsive force of the base material 11. It has come to be. Furthermore, the skin material 12 is brought into close contact with the inner surface WS of the outer wall W1 and the inner wall W2 and the outer surfaces 8A and 9A of the bathroom lower structure 1A by the repulsive force of the base material 11. Accordingly, the skin material 12 is continuously provided over the inner wall WS of the outer wall W1 and the inner wall W2 that are in close contact with each other and the outer surfaces 8A and 9A of the bathroom lower structure 1A. The gap G is closed, and the upper part of the installation space S and the underfloor space UF are configured so as not to communicate with each other.

  Next, a procedure for attaching the airtight member 10 will be described as a construction method for the bathroom unit 1. First, as shown in FIG. 2, the bathtub 3 and the washing floor 4 are installed on the foundation slab FS in the installation space S through the bundle 2 and the like, and the side portion is vertically disposed between the bathtub 3 and the washing floor 4. The material 8 is attached and the bathroom lower structure 1A is assembled. At this time, since each constituent member of the bathroom unit 1 needs to be carried into the installation space S, the inner wall W2 of the inner wall W2 that partitions the bathroom and the dressing room (the inner wall W2 indicated by a two-dot chain line in FIG. 2) ) Is not built. Thus, by installing the bathroom lower structure 1A inside the installation space S, a gap G is formed between the inner surface WS of the outer wall W1 or the inner wall W2 and the outer surfaces 8A and 9A of the bathroom lower structure 1A.

  After the bathroom lower structure 1A is installed, the airtight member 10 is press-fitted into the gap G as shown in FIG. As the press-fitting procedure of the airtight member 10, for example, the airtight member 10 is press-fitted from the gap G between the outer surface 9A of the rising piece 9 of the bathtub 3 and the inner surface WS of the outer wall W1 located on the back side as viewed from the entrance of the bathroom. To start. Subsequently, the airtight member 10 is pressed into the gap G between the outer wall W1 and the inner surface WS of the inner wall W2 on the left and right of the bathtub 3, and the outer surface 8A of the side vertical member 8 of the bathtub apron 7 and the outer wall W1 and the inner wall W2 After the airtight member 10 is pressed into the gap G with the inner surface WS, the airtight member 10 is pressed into the gap G between the outer surface 9A of the rising piece 9 of the washing floor 4 and the inner surface WS of the outer wall W1 or the inner wall W2.

  When the airtight member 10 is press-fitted into each gap G, as shown in FIG. 4, the airtight member 10 is folded in two so that the skin material 12 faces outward, and the skin material 12 on the bent front end side is separated by the gap G. The airtight member 10 is press-fitted while the skin 12 is slid along the outer surface 9A and the inner surface WS by inserting and pushing a hand or a tool between the base materials 11 on the back side. By the above press-fitting procedure, the press-fitting of the airtight member 10 into the gap G between the outer surfaces 8A and 9A on the three sides of the periphery of the bathroom lower structure 1A and the inner surfaces WS of the outer wall W1 and the inner wall W2 is completed. In addition, since the inner wall W2 which partitions a bathroom and a dressing room has not been built yet, the airtight member 10 is press-fitted in the procedure described later.

  By press-fitting as described above, the repulsive force due to the elasticity of the base material 11 acts on the inner surface WS of the outer wall W1 and the inner wall W2 and the outer surfaces 8A and 9A of the bathroom lower structure 1A, and the friction generated due to this repulsive force. The hermetic member 10 is held in the gap G by the force. As a means for increasing the holding force of such an airtight member 10, as shown in FIG. 5, the airtight member 10 may be affixed to the inner surface WS and the outer surfaces 8A and 9A using a double-sided tape T. Specifically, as shown in FIG. 5A, one surface of the adhesive layer T1 of the double-sided tape T is bonded to the inner surface WS of the outer wall W1, the inner wall W2, and the outer surfaces 8A and 9A of the bathroom lower structure 1A. Then, the other release paper T2 is left without being peeled off. After press-fitting the airtight member 10 while sliding the skin material 12 between the release paper T2, as shown in FIG. 5B, the skin material of the airtight member 10 is pulled out while peeling the release paper T2 in order from the end. 12 and the other surface of the adhesive layer T1 of the double-sided tape T are bonded together.

  Next, the procedure for press-fitting the airtight member 10 into the gap G between the inner surface WS of the inner wall W2 that partitions the bathroom and the dressing room and the outer surface 9A of the upright piece 9 of the washing floor 4 will be described with reference to FIG. To do. First, before building the inner wall W2 on the dressing room side, the wall panel 5 and the ceiling panel 6 are attached in the installation space S, and the assembly of the bathroom unit 1 is completed. Thereafter, as shown in FIG. 6A, the airtight member 10 is temporarily fixed to the rising piece 9 of the washing floor 4. At this time, the airtight member 10 is adhered to the outer surface 9A with the double-sided tape T, and the airtight member 10 is held with the temporary fixing tape T3 in a state where the airtight member 10 is rolled so that the skin material 12 faces outward. Moreover, the double-sided tape T is stuck on the part which the inner wall W2 by the side of the dressing room in the airtight member 10 contact | abuts.

  The inner wall W2 is built from the dressing room side to the airtight member 10 temporarily fixed to the rising piece 9 of the washing floor 4 as described above, and the airtight member 10 is sandwiched between the rising piece 9 and FIG. As shown in (B), the airtight member 10 is folded in half by being pressed by the face material P of the inner wall W <b> 2, and the skin material 12 is exposed to the outer surface of the rising piece 9 of the washing floor 4 by the repulsive force of the base material 11. 9A and the inner surface WS of the inner wall W2 are in close contact. Furthermore, the airtight member 10 is held in the gap G by being bonded to the outer surface 9A and the inner surface WS by the double-sided tape T. Thus, in the place where it is between the wall panel 5 of the bathroom unit 1 which has been assembled and the inner wall W2 on the dressing room side, and it is difficult to work with a hand or a tool after the inner wall W2 is built. By preliminarily fixing the airtight member 10 to the rising piece 9 of the washing floor 4 in advance, the press-fitting work of the airtight member 10 can be performed simultaneously with the construction of the inner wall W2.

  According to this embodiment as described above, there are the following effects. That is, the airtight member 10 includes a base material 11 having elasticity and a skin material 12 having airtightness, and the airtight member 10 includes the outer surfaces 8A and 9A of the bathroom lower structure 1A and an installation space. By pressing into the gap G between the outer wall W1 and the inner wall WS of the inner wall W2 constituting the S, the skin material 12 is brought into close contact with the outer surfaces 8A and 9A and the inner surface WS by the repulsive force of the pressed base material 11, and the gap G Can be blocked. Moreover, since the airtight member 10 is held in the gap G by the repulsive force of the pressed base material 11, a separate fixing operation can be made unnecessary, and the construction labor can be reduced. Therefore, it is possible to improve the workability because the construction procedure is not restricted and the construction labor can be reduced. Further, the skin material 12 is brought into close contact with the outer surfaces 8A and 9A and the inner surface WS by the repulsive force of the pressed base material 11, thereby preventing a gap from being formed between these surfaces and the skin material 12. Can improve airtightness.

  The airtight member 10 is formed with a skin material 12 on the surface of one side of the base material 11 and bends the airtight member 10 so that the skin material 12 faces outward, and the inner surface WS of the outer wall W1 and the inner wall W2. By press-fitting the gap G with the outer surfaces 8A and 9A of the bathroom lower structure 1A, the skin material 12 can be brought into close contact with the inner surface WS and the outer surfaces 8A and 9A. Therefore, the airtight member 10 can be manufactured easily and inexpensively as compared with the case where the skin material 12 is provided on both surfaces of the base material 11. Furthermore, if the airtight member 10 is folded and press-fitted into the gap G, the workability of the press-fit becomes good and the workability can be further improved.

  Moreover, as shown in FIG. 5, if the airtight member 10 is stuck to the inner surface WS of the outer wall W1 or the inner wall W2 and the outer surfaces 8A, 9A of the bathroom lower structure 1A using the double-sided tape T, the repulsive force of the base material 11 In addition to the holding force for holding the airtight member 10, the airtight member 10 can be fixed by the adhesive force of the adhesive layer T <b> 1, so that the airtight member 10 can be prevented from being displaced and dropped and the airtightness can be maintained. it can. At this time, one surface of the adhesive layer T1 is affixed to the inner surface WS and the outer surfaces 8A and 9A, the airtight member 10 is press-fitted while leaving the release paper T2 on the other surface, and after the press-fitting, the release paper T2 is peeled off and pulled out. Thus, the fixing strength of the airtight member 10 can be easily increased without reducing the workability.

  In addition, this invention is not limited to the said embodiment, Including other structures etc. which can achieve the objective of this invention, the deformation | transformation etc. which are shown below are also contained in this invention. For example, in the said embodiment, although the airtight structure of the bathroom unit 1 installed in the installation space S was illustrated, the airtight structure of this invention is not restricted to the bathroom unit 1, Arbitrary installation members are installed in installation space. At this time, the installation member and the installation space are not particularly limited as long as a configuration in which a gap between the outer surface of the installation member and the inner surface of the installation space is closed with an airtight member is provided. That is, the installation space is not limited to the space provided inside the building and surrounded by the outer wall W1 and the inner wall W2, but may be a space surrounded by members other than the walls. Further, the installation member is not limited to the bathroom lower structure (unit member) 1A, but a member different from the constituent members of the bathroom unit 1 is attached, and the airtight member is in close contact with the member. Also good.

  In the above embodiment, the airtight member 10 is provided with the skin material 12 provided on the surface of one side of the base material 11, but is not limited thereto, and the skin material 12 is provided on both surfaces of the base material 11. It may be. Furthermore, in the said embodiment, although the airtight member 10 was folded in half and it press-fitted in the clearance gap G, it should just be bent so that the skin material 12 may face outward, and the frequency | count of the bending is not specifically limited. Moreover, in the said embodiment, when the space | interval dimension of the clearance gap G is 20 mm, the thickness dimension of the airtight member 10 folded in half is 1.1 times-3.0 times the space | interval dimension of the clearance gap G. However, it is not limited to such dimensions. That is, the thickness dimension of the hermetic member to be press-fitted with respect to the gap dimension of the gap G may be set as appropriate within a range of 1.1 times or more and 3.0 times or less. If the size is increased, the close contact force of the skin material can be increased, and if the size is decreased, the workability of the press-fitting work can be improved and the material can be saved.

  Moreover, in the said embodiment, after installing the bathroom lower structure 1A in the installation space S as a press-fitting procedure of the airtight member 10 with respect to the gap G, the gap between the outer surfaces 8A, 9A and the inner surfaces WS of the outer wall W1 and the inner wall W2 In the case of press fitting into G, the airtight member 10 is temporarily fixed to the outer surface 9A of the bathroom lower structure 1A and then the inner wall W2 is built, and the airtight member 10 is interposed between the inner surface WS and the outer surface 9A of the bathroom lower structure 1A. Although the two procedures of the case of press-fitting by sandwiching are described, the order of obtaining these pressures is not limited. That is, before installing the bathroom lower structure 1A, the airtight member 10 is temporarily fixed to the inner surface WS of the outer wall W1 or the inner wall W2, and the airtight member 10 is sandwiched when the bathroom lower structure 1A is installed. Also good.
