Description

Piping horizontal maintenance device of the penetrating joint for piping

The present invention relates to a pipe leveling device of a pipe through joint device, and more particularly, a pipe support ring inside the packing at both ends of a joint device installed to prevent leakage of a pipe passing through it in a state where it is located on a wall. It relates to a pipe leveling device of a pipe through joint device that allows the pipe to be installed through the installation to be horizontally maintained so that the pipe connection work can be done quickly and conveniently, and to provide an accurate coupling of the fastening flange will be.

In general, in the case of new construction or remodeling of buildings such as apartments, houses, and buildings, pipes for gas, heating, water supply, and sewage pass through the wall.

However, when the pipe is installed so that it passes directly through the wall, a gap is formed between the wall and the wall as it contracts or expands by the thermal expansion coefficient of the pipe. There are many difficulties.

In order to prevent such a defect, when a penetrating pipe passes, a joint pipe is installed inside the wall and fixed with concrete.

The joint is connected so that the center of the body is penetrated and the pipe is later passed through to prevent water leakage inside.

However, there is a leak phenomenon in which the moisture moves along the gap between the outer surface of the body and the wall, but there is a drawback that this leak phenomenon cannot be prevented.

In addition, when the wall is poured with concrete after the formwork is installed, the concrete is poured while the joint pipe is located inside the formwork. there was

In addition, the joint work is performed by supplying the pipe while the joint pipe is fixed to the wall, but the pipe that has passed through the inner diameter of the joint pipe is fixed from both sides to prevent water leakage. For this reason, the inner diameter through which the pipe is penetrated is molded so that there is a large margin compared to the size of the pipe, so the fastening flange is not perfectly installed on the inner diameter part due to the gap. As it is deformed so that it cannot be deformed, the level of the pipe was not maintained normally during the connection work between the pipe passing through the joint pipe, the packing and the flange while performing the pipe work, which caused leakage, defects, and defects.

In order to prevent such a defect, if the inner diameter of the joint pipe and the outer diameter of the pipe are not left with a margin, the pipe is not inserted well, which causes a lot of difficulty in the pipe work.

The joint pipe 100 is formed by connecting one more joint pipe 110 according to the wall thickness of the building. (13) to be butt each other, the inner diameter is to be installed so that the packing 40 and the pipe support ring 50 on both sides.

If the width of the wall cannot be accommodated even when the joint pipes 100 and 110 are connected, one more joint pipe 120 is connected to one side of the joint pipe 110 and used,

After connecting the fittings 100 and 110, the fixing flanges 13 are butted to each other without the mounting base 20 and the fastening flange 30 on one side of the fittings 110, and the inner diameter is filled with packing (40) on both sides. ) and the pipe support ring 50 are connected to one side such that a plurality of fittings are connected to fit the width of the wall and used.

The pipe leveling device of the through joint device for piping of the present invention having such a configuration forms a form to install the joint pipe 100 through the wall and drives it with a nail through the nail hole 21 of the installation table 20. Accurately set the installation location.

By pouring the wall with concrete or the like using a formwork, the joint pipe 100 is penetrated and is integrally installed.

The flange 10 in the center has a diameter of at least twice that of the cylindrical body 11 so that it is relatively large so that there is no gap with the wall to block the flow of moisture, and the cylindrical body 11 of The outer diameter is circular and protrudes at regular intervals, and the reinforcing protrusions 12 protrude in the transverse direction and are combined with the wall in the form of irregularities to block the flow of moisture to prevent water leakage, and at the same time, reinforcing protrusions 12 in the circular and transverse directions.

As described above, after the pipe 60 is supplied to the joint pipe 100 in a penetrating state, a load or pressure is applied to the pipe 60 with soil, etc. ) through the inner diameter and the gap that occurs, the deformation is inclined to one side. It is a cause of leakage because the work is terminated inappropriately.

However, when the pipe support ring 50 is inserted into the support grooves 15 formed on both sides of the inner diameter of the cylindrical body 11, it is separated due to the end face 52 of one part, so that the pipe 60 does not get caught when connecting through it. After the pipe 60 is penetrated, the outer diameter and the gap of the pipe 60 are wrapped so that almost no gap is generated and the fixed state is provided by the inner diameter of the fixed plugs 13 on both sides, so the soil of the pipe 60 is When the piping work is carried out by preventing the pipe 60 from being twisted or tilted even when the operation of supplying, etc. is performed, it provides a state in which the pipe 60 is not deformed and proceeds conveniently and accurately, thereby preventing leakage. that can be prevented.

On the outside of the fixing flange 13, the screw shaft 33 is screwed to the connection nut 17, and when a part protrudes, it penetrates the flange hole 32 and protrudes through the flange hole 32, and the fastening nut is attached to the screw shaft 33 ( 34) to perform the tightening operation.

When the fastening nut 34 is tightened, the screw shaft 33 presses the fastening flange 30 inward, and the fastening protrusion 31 formed inside the fastening flange 30 is a packing in the packing groove 14 . Press (40) to prevent leakage from the outer diameter of the pipe (60) by pressing, and the inner inclined surface (41) of the packing (40) is fixed to the packing of the pipe support ring (50) inside the packing groove (14) It is to provide a solid and stable bonding state so that water leakage does not occur while being in close contact with the surface 51 .
