Description

Assembled piping shaft for high-rise building

Technical Field

The utility model belongs to the technical field of the piping shaft technique and specifically relates to an assembled piping shaft for high-rise building.

Background

As an important component of residential engineering, a piping shaft needs to have the following functions:

1. the function needs. The more complex and advanced buildings require more support systems, and besides basic water supply, power supply, fire protection, heating, direct drinking water and other pipelines, telephones, cable televisions, monitoring, ventilation and the like are required, and the development of the buildings is increased at any time.

2. Safety requirements. The multiple pipelines are concentrated in a building and are inevitably influenced mutually, so that the pipelines with similar functions and safety need to be concentrated, the pipelines with high risk need to be independently closed, and the pipelines are prevented from being damaged manually.

3. And (4) the appearance is required. When various pipelines are obviously installed, the cleanness of a building is influenced, and the pipeline well only occupies a small space and can be completely hidden.

The construction steps of the existing pipe well generally adopt the following steps:

1. reserving pipeline holes when floor concrete is poured;

2. building a filler wall after the primary structure is finished;

3. pouring concrete of secondary structures such as doorways, constructional columns and the like;

4. installing a pipeline bracket;

5. plastering the wall and ceiling in the conduit shaft;

6. installing various pipelines in the pipeline well;

7. the periphery of the preformed hole is blocked;

8. constructing the ground of the pipe shaft;

9. installing a pipeline well door;

10. constructing the inner wall coating of the pipe shaft;

11. pipeline painting;

12. and (5) insulating the pipeline.

The construction defects of the existing pipe shaft are mainly reflected in the following aspects:

1. the working procedures are complicated and long in construction period, 12 working procedures are carried out in a place with the square meter less than 1.5 and are all carried out by manpower, and the construction period is difficult to guarantee under the condition that construction manpower is deficient.

2. The operation space is narrow, about 13 vertical pipes are required to be installed in the place with the square meter less than 1.5, and household metering equipment such as a water meter and a heat meter is required to be installed.

3. The construction quality is difficult to guarantee, because the decoration construction can be carried out after the pipeline installation is finished, only manual operation is needed, and the difficulty of the decoration behind the pipeline is huge. The pipeline bracket is difficult to be installed on the filling wall; and the plastering quality of the inner wall of the air shaft is difficult to ensure, the air leakage is serious, the inner wall is not smooth, and the wind speed value cannot meet the requirement of a user.

4. The construction cost is high, and the construction cost far exceeds the rated cost because the mechanized production can not be carried out and the manpower is completely relied on.

Therefore, there is a need to provide an improved scheme for the existing piping shaft structure to increase the construction speed and quality of high-rise buildings and meet the development requirements of the modern building industry.
