Description

Step difference compensation type double through sleeve}

The present design can be directly connected without generation of a step, as well as a separate auxiliary pipe for each generation located in the groove formed on the concrete floor layer after being placed in the concrete floor layer or cured of the poured concrete before being placed in concrete. It relates to a step-compensated double through sleeve without risk of defects, such as water leakage, as a rapid construction is possible because no drilling work is required.

In the construction of concrete buildings such as apartments and buildings, through-sleeves of various specifications are installed on concrete floors and formwork of concrete walls to secure pipelines for water pipes, drain pipes and sewer pipes, air conditioners, gas pipes, and various communication cables. .

The through-sleeve is usually formed in a cylindrical shape, and a removable cap is provided on one side, and a fixture for fixing to the formwork is provided on the other side. The through-sleeve fixed to the formwork through this fixture is used for piping through water pipes, drain pipes and sewer pipes, air conditioners, gas pipes, and various communication cables by removing the lid after the concrete pouring is completed.

On the other hand, the main pipe connecting the layers and the auxiliary pipe through which sewage flows by generation are connected by a double through sleeve called a peanut sleeve. At this time, since the main pipe has a larger inner diameter than the auxiliary pipe, the double penetration sleeve is usually formed to be relatively large to allow the main pipe having a large inner diameter to pass through, and to be formed relatively small to allow the secondary pipe to have a smaller inner diameter than the main pipe. It is formed in parts.

And at the lower end of the double through sleeve, a swirling force is generated in the running water so that the air core is maintained, so that a drain connector capable of both draining and venting is used as a single pipe.

However, in recent years, as the minimum height to the floor and ceiling is limited by the construction law, there are increasing cases of securing the height to the floor and ceiling by including subsidiary pipes such as kitchen pipes for each floor or household by being included in concrete. At this time, the method of including the auxiliary pipe in the concrete is a method of connecting the auxiliary pipe with the double through sleeve before pouring concrete, and forming a groove through which the auxiliary pipe can be accommodated in the concrete after curing the concrete to the double through sleeve. Method is optionally used.

However, the conventional double through sleeve has a problem that the end of the auxiliary pipe included in the concrete cannot be directly connected to the side of the double through sleeve because the upper end of the portion where the main pipe is connected and the portion where the auxiliary pipe is connected is the same.

That is, because the top of the double penetration sleeve is the same height as the top of the concrete floor layer, the end of the auxiliary pipe buried in the concrete layer or accommodated in the groove cannot be directly connected without perforating the side portion of the double penetration sleeve.

Therefore, there is a problem that air may be delayed due to the perforation of the double penetration sleeve, and a defect such as water leakage may occur after the building is completed due to the damage of the double penetration sleeve that may occur during perforation.
