Description

Duplex flexible pipe for double wall {duplex flexibility pipe for duplex wall}

The present invention relates to a double stretch tube for double walls, and more particularly to a double stretch tube for a double wall construction wall is double construction and penetrated through such a double wall.

Generally, when constructing a building, a wall may be doubled, and one of the spaces and the other of the spaces may be used for completely different purposes, and the pipe may pass through the two spaces described above. Equipment can be constructed.

As an example of the above-described building, it may be an underground reservoir tank of an apartment complex, an underground parking lot, or the like, and as another example, it may be a structure to prevent external infiltration water such as a water purification plant and a sewage treatment plant of a civil engineering facility.

As another example of the above-described building, it may be a fire fighting facility that penetrates the floor of the building, a duct of an air conditioning facility, a water and sewage pipe, a pipe for electric wire construction, and the like.

The wall of such a building may be doubled, and when the pipe is penetrated through the double wall, it may cause fatal damage to the pipe due to expansion and contraction of the structure, and to repair the damaged part according to the material properties. There is a very difficult problem.

More specifically, one of the double walls and the other of the double walls may be displaced or shaken due to an earthquake, ground subsidence or unknown reason, in which case a shear load may be applied to the pipe. There is a problem that the pipe is abnormally deformed or damaged by the shear load.

On the other hand, as a packing for a pipe used when constructing a wall, there is a domestic registered utility model publication No. 20-0331277 "Pipe installation packing for wall construction".

The pipe mounting packing described above relates to a packing proposed to allow easy installation of a pipe when a wall is constructed, and has a structure in which a plurality of protrusions are formed in a through hole formed in a cylindrical shape.

That is, the above-described conventional pipe mounting packing is configured to insert a pipe into a through hole in a state of being installed on a wall so that a plurality of protrusions are brought into close contact with the outer diameter of the pipe. It acts to prevent it from being driven to the wall.

However, the above-described conventional pipe mounting packing is not suitable for a special building structure such as a double wall, and the reason for the unsuitable reason is that a double wall may be arranged with insulation or expansion joints such as styrofoam in the middle of the double wall. In addition, the water may penetrate along the surface of the insulation or the expansion joint, there is a problem that the water that penetrates can be moved along the packing and introduced into the room in the wall in which the conventional pipe mounting packing is constructed.

In addition, the packing may be excessively deformed when either wall becomes uneven in the double wall, and the packing may be spaced apart from the building structure, and water penetration may occur through the gap. There is a problem.

As another example of the prior art, Korean Patent Application Laid-open No. 1-2006-0053481 "waterproof fixed cover for building wall passing piping" is known.

The conventional waterproof fixing cover has a configuration in which the first and second covers are formed in a bolt and nut shape, and a pipe for piping is fitted in the middle of the first and second covers.

In addition, a packing is disposed in the outer diameter portion and the inner diameter portion of the first and second covers.

The above-mentioned conventional waterproof fixing cover is formed by first mounting holes of a predetermined size through a wall (urethane panel, grouse panel or various panels), and the pipes are fitted into the installation holes, respectively, on both sides of the wall. The first cover and the second cover are fitted, and the first cover and the second cover are fastened by screwing.

However, the above-mentioned conventional waterproof fixing cover must rotate the first cover or the second cover in a spiral when screwed together, and in this rotation process, slip phenomenon may occur between the waterproof fixing cover and the wall or the waterproof fixing cover and the pipe. In this process, the packing may be deformed and deformed to either side, and the deformed packing may not be expected to have the effect of airtight or watertight retention.

Therefore, the technical problem to be achieved by the present invention is to prevent the infiltration water flowing between the double wall to enter the room when constructing the pipe to penetrate the wall consisting of a double and abnormally settle the ground or sedimentation due to earthquake, etc. It is an object of the present invention to provide a double expansion pipe for double walls that does not adversely affect the pipe installed therein even if it occurs.
