Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof sheet for outer walls in a unit type building.

[0002]

2. Description of the Related Art In a so-called unit type building, an outer wall panel is attached to each unit body. Therefore, for example, a connecting portion between the first-floor unit body and the second-floor unit body or 2
The edge portion of the outer wall panel is located at the connecting portion between the floor unit body and the roof unit body.

In order to maintain the water resistance of the building by covering the edge portion, the outer wall panel and the unit body of the above-mentioned portion are conventionally provided as disclosed in JP-A-1-33335 and JP-A-1-33336. There is a waterproof sheet for the outer wall arranged between. The outer wall waterproof sheet is attached to a beam or a stud arranged in the unit body with an adhesive or the like.

[0004]

Some unit bodies do not have the beams and studs, which are convenient for mounting the outer wall waterproof sheet. In such a case, in the conventional outer wall waterproof sheet, only its upper corner is attached to the pillar of the unit body, and most of the upper edge portion of the outer wall waterproof sheet remains unsupported.

For this reason, the mounting workability is not good, and the number of steps and working time are long.

The present invention has been made in consideration of the present situation as described above, and provides an outer wall waterproof sheet which has a good mounting workability and can reduce man-hours and working time. It is intended.

[0007]

In order to solve the above-mentioned problems, in the outer wall waterproof sheet according to claim 1, an attachment auxiliary member extending between a pair of pillars located on the outer wall portion of the building unit is provided at the upper edge portion. It is characterized by being installed along.

Further, in the outer wall waterproof sheet according to a second aspect of the invention, the attachment auxiliary material is made of polypropylene.

Further, in the outer wall waterproof sheet according to a third aspect of the present invention, the attachment auxiliary member has a bent cross section.

[0010]

According to the outer wall waterproof sheet of claim 1,
Since the mounting auxiliary material that extends between the pair of pillars located on the outer wall of the building unit is installed along the upper edge, the upper edge of the outer wall waterproof sheet was linearly and firmly supported by the mounting auxiliary material. It has become a thing. Therefore,
Even if a convenient beam or stud is not provided for mounting, reliable mounting work can be easily performed.

Further, according to the outer wall waterproof sheet of the second aspect, since the attachment auxiliary material is made of polypropylene, the work such as cutting and nailing is easy. Further, it is possible to secure a certain level of strength even if the wall thickness is reduced, and it is possible to reduce the weight. In addition, there is an advantage that rust does not occur and the material cost is low.

Further, according to the outer wall waterproof sheet of the third aspect, since the mounting auxiliary member has a bent cross-section, it is arranged between the outer wall panel and the pillar, etc., and is deformed into a straight line in cross section. The attached auxiliary material has a restoring force for returning to the bent shape. This suppresses the generation of gaps between the outer wall panel and the pillar, and improves the waterproof performance.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the outer wall waterproof sheet of the present invention will be described below with reference to the drawings. 1 to 3 show a first embodiment.

In FIG. 1, reference numerals 1 and 2 denote a pair of columns located on the outer wall of a building unit (not shown), and no beams or studs are arranged between them. Outer wall panels 3 and 4 are arranged outside the columns 1 and 2. In addition,
The arrangement structure of the outer wall panels 3, 4 and the like is not within the technical scope of the present invention, and thus the description thereof is omitted.

Between the pillars 1 and 2 and the outer wall panels 3 and 4,
As shown in FIG. 3, an outer wall waterproof sheet 5 for preventing intrusion of rainwater from the gap S between the outer wall panel 3 and the outer wall panel 4 is provided.

The outer wall waterproof sheet 5 is made of soft synthetic rubber having a high waterproof property and is wider than the gap S. Then, an attachment auxiliary member 6 having a length extending between the columns 1 and 2 is attached to the upper edge portion thereof by adhesion.

The mounting aid 6 is made of polypropylene and has a bent cross section as shown in FIG.

As shown in FIG. 3, the outer wall waterproof sheet 5 is sandwiched between the outer wall panel 3 and the pillar 1 with its lower bent portion aligned with the lower edge of the outer wall panel 3. The mating surface on the side of the pillar 1 is attached by an adhesive.

FIG. 4 shows an application example. By attaching the outer wall waterproof sheet 5 in a state in which the upper bent portion of the outer wall waterproof sheet 5 is aligned with the lower edge portion of the outer wall panel 3, the incidental equipment 7 (for example, protruding from the outer end surface of the pillar 1) The outer wall waterproof sheet 5 can be provided without touching the floor heating device controller.

Next, the operation of the outer wall waterproof sheet will be described.

Since the mounting auxiliary member 6 extending between the pair of pillars 1 and 2 located on the outer wall portion of the building unit is mounted along the upper edge portion, the entire upper edge portion of the outer wall waterproof sheet 5 is used for this mounting assistance. The material 6 is linearly and firmly supported. Therefore, even if a convenient beam or stud is not provided for mounting, reliable mounting work can be easily performed.

Further, since the mounting auxiliary material is made of polypropylene, the work such as cutting and nailing is easy. In addition, polypropylene is a synthetic resin and has a characteristic that it can secure a certain degree of strength even if the wall thickness is thin, and therefore, it is possible to reduce the weight. In addition, there is an advantage that rust does not occur and the material cost is low. Furthermore, since the attachment support member 6 has a bent cross section,
After being arranged between the outer wall panels 3 and 4 and the pillars 1 and 2, and being deformed along a straight line in cross section, it has a restoring force for returning to the original bent shape. By this, the outer wall panel 3,
It is possible to suppress the generation of gaps between the column 4 and the columns 1 and 2 and improve the waterproof performance over a long period of time.

The present invention is not limited to the above embodiments, and design changes made by those skilled in the art are also included in the technical scope of the present invention. For example, in the above-mentioned embodiment, the waterproof sheet for the outer wall covering the entire width of one building unit is mentioned, but a waterproof sheet for a limited part of the outer wall of the building is also included in the technical scope of the present invention.

[0024]

As described above, according to the first aspect of the present invention, reliable mounting work can be easily performed even if convenient beams or studs are not provided for mounting. Exert the effect of being able to.

According to the second aspect of the invention, it is possible to facilitate the work such as cutting and nailing, reduce the weight while ensuring the strength, prevent rust, and reduce the cost of members. Be effective.

Further, according to the invention described in claim 3,
It is possible to suppress the generation of gaps between the outer wall panel and the pillars, and it is possible to improve the waterproof performance over a long period.
