DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealing method using a thin film for sealing a penetration part of a building drawn into a building outside wall, and more particularly to a sealing method capable of uniformly filling a sealing material to obtain a reliable sealing. The present invention relates to a sealing method using a thin film which is suitable for a method.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, a sealing material applying tool 2 filled with a sealing material 1 is used to seal a portion where a pipe such as a duct drawn into a room penetrates an outer wall of a building. While pressing the sealing material applying tool 2 to push out the sealing material 1, the pipe 3
The sealing material 1 is applied to the penetrating portion 5 penetrating through the substrate and is laid.

[0003]

However, in such a conventional method of applying the sealing material 1, it is difficult to keep the pressing force of the sealing material applying tool 2 constant.
When applying the sealing material 1 to the through portion 5, a portion where the amount of the sealing material 1 applied is too large or conversely tends to be insufficient, and the sealing material 1 is uniformly applied around the through portion 5. There is a problem that it is difficult to obtain a reliable sealing.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a simple and reliable method by uniformly applying a sealing material to a penetration part of a building exterior wall of a pipe drawn indoors. An object of the present invention is to provide a sealing method using a thin film capable of performing sealing.

[0005]

According to the present invention, in order to achieve the above object, a sealing material sealed with a thin film is disposed in a gap defined by two opposing faces, and the opposing faces are provided. The method is characterized in that the thin film is broken between two surfaces and the gap is filled with a sealing material.

[0006]

According to the present invention having the above-mentioned structure, a sealing material sealed with a thin film is disposed in a gap defined by two opposing surfaces, and the thin film is interposed between the two opposing surfaces. Was destroyed, and the gap was filled with a sealing material.
The sealing material can be uniformly distributed and filled between the two opposing surfaces, and a reliable sealing can be obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a side sectional view of a sealing material-filled thin film 10 as a sealing material sealed with a thin film according to the present invention. The sealing material-filled thin film 10 includes a sealing material 12 and a thin film 14 that seals the sealing material 12. As the sealing material 12, a material suitable for the area to be sealed, the surface condition, and the like is appropriately selected. Also, the amount of the sealing material 12 to be sealed may be appropriately adjusted in accordance with the area of the place to be sealed and the like.

As the thin film 14, various types of synthetic resin films can be used, but considering that they cannot be used repeatedly, the cost is as low as possible under the condition that a predetermined strength can be obtained. It is desirable to use Further, if the film is formed of a film having an even thickness, it is difficult to predict from which part the film will be broken, and the sealing material 12 may flow out of the sealing portion, and sufficient sealing may not be obtained. . Therefore, if a weak portion is formed in the strength, for example, the film thickness is partially reduced in advance, the weak portion is destroyed first, and the sealing material 1 is removed therefrom.
Since 2 flows out, the sealing can be effectively performed by arranging this weak portion at the seal location.

FIG. 2 shows a structure in which the pipe 20 penetrates the building outer wall 30 by using the sealing material-filled thin film 10 in which the sealing material 12 is sealed, using the building outer wall 30 and the flange 22 as two opposing surfaces. FIG. 7 is a partially cutaway side sectional view showing a case where a gap defined by a flange 22 and a flange 22a is sealed. FIG. 2 shows a state before the pipe 20 is fixed to the building outer wall 30. The pipe 20 penetrating the building outer wall 30 has a flange 2
2 are provided, and are connected by a bolt 24 to a pipe 20a also having a flange 22a. The bolts 24 inserted into the flanges 22 and 22a extend to the building outer wall 30 and are engaged with screw holes provided in the building outer wall 30. Between the flange 22 provided on the pipe 20 and the building outer wall 30, and between the flange 22 and the flange 22a, the sealing material-filled thin film 10 in which the sealing material 12 is sealed is provided and fixed. . When fixing the sealing material-filled thin film 10, it may be temporarily fixed with an adhesive or the like so as not to move when the bolt 24 is tightened. Further, the weak portion provided on the thin film 14 forming the above-described sealing material-filled thin film 10 is located on the inner side of the flanges 22, 22 a, that is, the pipes 20, 20.
If the sealing material-filled thin film 10 is fixed so as to be disposed on the side of the sealing material 12, the sealing material 12 sufficiently spreads between the flange 22 and the building outer wall 30 and between the flange 22 and the flange 22 a, thereby ensuring reliable operation. Sealing can be obtained. The filling amount of the sealing material 12 is determined by adjusting the amount of the sealing material 12 sealed in the sealing material-filled thin film 10 or by adjusting the number of the sealing material filled thin films 10 in which the sealing material 12 is sealed. do it.

Next, the operation of the present invention will be described with reference to FIG. 2 and FIG. FIG. 3 is a partially cutaway side sectional view showing a case where a portion where the pipe 20 penetrates the building outer wall 30 is sealed using the sealing material-filled thin film 10 in which the sealing material 12 is sealed, similarly to FIG. It is.
FIG. 3 shows a state after the pipe 20 is fixed to the building outer wall 30. From the state shown in FIG.
Is tightened, the flange 2 provided on the pipe 20 is
2 and the outer wall 30 of the building, and the interval between the flange 22a provided on the pipe 20a and the flange 22 are becoming narrower, and between the flange 22 and the outer wall 30 of the building, and
The sealing material-filled thin film 10 in which the sealing material 12 disposed between the flange 22 and the flange 22a is sealed is compressed. When the pressure of the sealing material 12 sealed in the sealing material-filled thin film 10 exceeds the tensile strength of the weak portion formed on the thin film 14 constituting the sealing material-filled thin film 10, the strength is reduced. The thin film 14 breaks from the weakly formed portion, and the gap between the flange 22 and the building outer wall 30
The gap between the flange 22 and the flange 22a is filled with the sealing material 12. When the bolts 24 are further tightened, the other parts of the thin film 14 are also destroyed, and all of the sealed sealing material 12 is released. When the bolt 24 is tightened with the specified tightening torque, as shown in FIG. 3, the gap between the flange 22 and the building outer wall 30 and the gap between the flange 22 and the flange 22a are completely filled with the sealant 12, and , The remaining sealing material 12 is extruded from these gaps and stays at the periphery of the sealing portion, and the flange 2
The gap between 2 and the building outer wall 30 and the gap between the flange 22 and the flange 22a are completely sealed.

As described in detail above, according to the present invention,
Exhibits the following excellent effects. (1) In a gap defined by two opposing surfaces,
A sealing material sealed with a thin film is provided, and
Since the thin film is broken between the two surfaces and the gap is filled with the sealing material, the sealing material can be uniformly distributed and filled between the two opposing surfaces, and a reliable sealing can be achieved. Obtainable. (2) A sealing material sealed with a thin film is provided at the sealing location,
Since a reliable sealing can be obtained only by performing a predetermined pipe fixing operation, no special skill is required, and labor saving in the sealing operation can be achieved.
