DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an airtight structure around a unit structure that partitions a space between a unit structure such as a bathroom unit installed in a building and an inner surface of the unit installation space.

[0002]

2. Description of the Related Art In recent years, bathroom units have been widely used in general residential buildings. In this bathroom unit, a waterproof pan as a floor member, a wall panel, a ceiling panel, a bathtub and other bathroom components are produced in a factory in advance, carried into a construction site as a unit, where the components are assembled, and a building unit is assembled. Although a bathroom is constructed by installing it in an installation space, when a bathroom is constructed using this bathroom unit, there is a problem that a large gap is generated around the unit as a specific problem.

[0003] In the case of construction using a bathroom unit as compared with the method of painting a wall directly on a wooden shaft, the unit installation space of the building is secured to be a certain size larger than the size of the bathroom unit. When a bathroom is constructed by assembling panels, ceiling panels, etc., a certain gap is formed between the waterproof pan and the wall panel and the inner surface of the unit installation space. It is not stretched, and the columns and the like are exposed as they are, and a space is created between the columns.

[0004] On the other hand, in recent years, demands for high airtightness and high heat insulation in residential buildings have increased, and therefore, countermeasures have been demanded in construction using the bathroom unit. As one of the countermeasures, there is a method of packing glass wool as a heat insulating material between a waterproof pan which is a floor member of a bathroom unit and an inner surface of the unit installation space, but as shown in FIG. In the case where the ribs 202 are present, the ribs 202 hinder the glass wool from closely adhering to the outer surface of the waterproof pan 200, and there is a problem that a gap is generated and sufficient heat insulating properties cannot be obtained. There is a problem that the cost is high and the construction is troublesome.

In addition, when the gap between the waterproof pan and the inner surface of the unit installation space is narrow, if the glass wool is forcibly packed there, the waterproof pan is lightweight when no wall panel is placed thereon. In addition, there is a problem that the waterproof pan moves due to the compression repulsive force of the glass wool and is installed at a position deviated from a fixed position.

FIG. 6 and FIG. 7 show other solutions conventionally proposed. FIG. 6 shows that the elastic sealing material 208 such as rubber is provided between the bathroom unit 204 and the inner surface of the unit installation space at the lower and upper portions of the gap 206 between the bathroom unit 204 and the inner surface of the unit installation space. 7 to provide heat insulation (disclosed in JP-A-8-4329).
(A) and (B) show that a separate interposition material 210 is further arranged below the waterproof pan 200 in the bathroom unit, and the interposition material 210 allows the lower space of the waterproof pan 200 and the upper side to be arranged. A space between the outer peripheral edge of the interposition material 210 and the inner surface of the unit installation space is cut off.
This is an example in which heat insulation is ensured by interposing 2 or 214 (disclosed in Japanese Utility Model Laid-Open No. 4-36054).

However, in the case of the technique shown in FIGS. 6 and 7, the sealing material 208 or the packings 212 and 214 each having elasticity are attached to the inner surface of the unit installation space, the wall panel of the bathroom unit, the waterproof pan, or the waterproof pan. A large compressive force has to be applied in the horizontal direction with the intervening member 210 on the lower side of 200 to interpose and intercept the gap. In addition, the distance between the waterproof pan 200 or the interposition material and the inner surface of the unit installation space is correct, and the sealing material 208 and the packing 21
The spacing must correspond to the dimensions of 2,214, and the position of the waterproof pan 200 can be adjusted according to the situation of the installation site, or can be adjusted according to various installation positions of the waterproof pan 200 at each site. There is a problem that it is difficult. Furthermore, the same problem as the above-described method of filling glass wool between the waterproof pan 200 and the inner surface of the unit installation space is included.

[0008] The above description has been made using a bathroom unit as an example.
This problem is a problem that can commonly occur when constructing unit structures such as a toilet unit and a shower room unit.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and has a simple structure to reliably attain airtightness between a unit structure and members of a building in which the unit structure is housed. It is an object of the present invention to provide an airtight structure around a unit structure that can be provided.

[0010]

The present invention is an airtight structure for hermetically sealing a space between a unit structure such as a bathroom unit installed in a unit installation space of a building and an inner surface of the unit installation space. A shielding member such as a flexible shielding film is wrapped around the entire periphery of the floor member or the like in the unit structure, one end of which is on the inner surface of the unit installation space, and the other end is of the unit structure. As a floor member
A unit in which the lower space and the upper space of the floor member are air-tightly sealed by the shielding film and the like in an airtight state, respectively , inside the vertical portion of the panel mounting portion in the waterproof pan. It is an airtight structure around the structure. Further, an airtight structure around a unit structure in which the one end of the blocking film is fixed to a base of the building.

According to the present invention, when a flexible film is used as a gap-blocking material, the cost is low and the construction is easy, and the position of the floor member may be slightly changed or the floor member may be installed in any manner. Regardless, the barrier film can be easily fixed to the floor member and the inner surface of the unit installation space, and the lower space and the upper space of the floor member can be in a shielded state. Further, since one end of the above-mentioned blocking film is fixed to the upper base on the building foundation, the lower space and the upper space of the floor member can be easily blocked.

For example, when one end of the shielding film is fixed to the building on the upper side of the base, as described above, the column is generally exposed on the upper side of the base. A space is formed between the lower part of the floor member and the space below the floor member. Therefore, unless a wall material is attached to the inside of the pillar and one end of the barrier film is fixed to the wall material, the lower part of the floor member must be fixed. The side space and the upper space cannot be satisfactorily shut off. However, when one end of the blocking film is fixed to the base extending in the horizontal direction, the lower space and the upper space of the floor member can be easily blocked because there is no unevenness in the mounting portion.

[0013]

Embodiments of the present invention will be described below in detail with reference to the drawings. In FIG. 1, a base 14 is provided horizontally on an upper end face of a foundation 10 of a building 12, and a column 16 is erected vertically at a predetermined position on the base 14, and a unit installation space 18 is formed inside the column 16.
