Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a pipe penetrating sleeve structure installed on the inner and outer walls, roof, floor, etc. of a building structure.

[Technical Background of the Invention and Problems Therewith] Conventional piping penetrations provided in building structures have been achieved by setting penetration sleeves in the walls.

Such a conventional pipe penetration part will be explained with reference to FIG. As shown in the figure, the penetration sleeve 12 is set on the wall 11 at the time of concrete pouring, and the wall 1 is penetrated so that the formwork used for concrete pouring can be reused.
The length is the same as the thickness of 1.

If there is a requirement for airtightness or watertightness for such piping penetrations, a 7-ohm filler 13 is installed around the penetration sleeve 12 to be set, then concrete is poured, and after the concrete hardens. After the Esaform 13 is removed, the short pipe 14 is welded to the penetrating sleeve 12. After that, the piping 16 is passed through the inside of the penetrating sleeve 12 and the boot rubber 15 is
was wearing.

However, with the conventional piping penetrations as described above, the decontamination of the concrete surface after removing the Esaform 13 is poor, and the aesthetic appearance after removing the Esaform 13 is also unsatisfactory, so that part must be repaired. There was a problem.

[Object of the Invention] The present invention has been made in view of the above circumstances, and its purpose is to provide a pipe penetration sleeve structure that has the airtightness and watertightness required for the pipe penetration part and has excellent decontamination properties. Our goal is to provide the following.

[Summary of the Invention] In order to achieve the object described in -, the present invention provides a penetrating sleeve with a disc in a pipe penetrating portion installed in a wall, roof, floor, etc. of a building facility, and a disc of the penetrating sleeve. This relates to a pipe penetrating sleeve structure in which a short pipe is fixed to the pipe and a boot rubber is attached to the short pipe.

[Embodiments of the invention] Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view of an embodiment of the present invention, and as shown in the figure, a short pipe 4 having a diameter larger than the diameter J of the penetrating sleeve 3 with a disc A and a penetrating sleeve 3 with a disc A is shown in FIG. A state in which a pipe penetrating sleeve portion is set on a building wall 1 is shown. Further, a boot rubber 6 is attached to straddle the piping 5 and the short pipe 4.

To explain the installation method of the pipe penetration sleeve according to the present invention, first, during concrete pouring, the penetration sleeve 2 with a disk is set at a predetermined penetration point of the building wall 1, and after pouring the concrete, the disk (+1 penetration sleeve 2 A short pipe 4 having a diameter larger than that of the penetrating sleeve 2 is welded and fixed to the circular plate 3. Next, after inserting the pipe 5 into the pipe penetration part, one end of the rear boot rubber is fixed to the pipe 5. The other end is fixedly attached to the short pipe 4 by a band 7 via a buffer gasket 1-8.

According to the piping penetrating sleeve structure of the present embodiment described above, it has airtightness and water-tightness, easy decontamination when contamination occurs, and also has a simple appearance.

Also, if you install the piping after setting the through sleeve as in the past, the piping may not be set in the center of the through sleeve due to installation errors, and it may be necessary to install the boot rubber even after installation. In the example, a short pipe whose diameter is larger than that of the through-sleeve is used, so it is possible to absorb construction errors in welding the disc of the through-sleeve and the short pipe, and it is difficult to install the boot rubber. Not really. Moreover, since the welding between the penetrating sleeve and the short pipe is in a straight-line shape, welding can be performed more easily than conventional butt welding, making it possible to simplify on-site work.

FIG. 2 is a sectional view of another embodiment of the present invention, and the only difference is that a disk-shaped short tube is used instead of the short tube in FIG. The same reference numerals are used to omit the detailed explanation.

The method for installing the pipe penetration sleeve according to this embodiment is as follows: First, during concrete pouring, the disk 44 penetration sleeve 2 is set at a predetermined penetration point in the building wall 1, and after concrete pouring, the disk 44 penetration sleeve 20 is installed. A disk 10 of a short tube 9 with a disk having a diameter smaller than the diameter J of this penetrating sleeve 2 is welded and fixed to the circular root 3. Next, after the pipe 5 is inserted into the pipe penetration part, one end of the boot rubber 6 is fixed to the pipe 5, and the other end is fixed to the short pipe 9 with a band 7 via a buffer gasket 8.

Note that the diameter of the short tube 9 may be larger than the diameter of the penetrating sleeve 2.

The piping penetrating sleeve structure of this embodiment has airtightness and watertightness as well as the above-mentioned embodiments, which facilitates decontamination when contamination occurs, and also provides a simple appearance. In addition, since the disc of the penetrating sleeve and the disc of the short pipe are welded, construction errors can be absorbed, there is no difficulty in installing the boot rubber, and conventional butt welding is easy. This makes it possible to weld to the surface, simplifying on-site work.

[Effects of the Invention] As explained above, according to the present invention, airtightness and watertightness can be satisfied as required, and superior effects such as improved decontamination performance and simplification of on-site work can be achieved. play.
