Description

Connector for Height Adjustment of Standpipes

The present invention relates to a connector for a standing pipe, and more particularly, to a connector capable of adjusting the height of a standing pipe, which can solve a difference in height between floors when piping between floors of a building.

In general, a standpipe (or vertical pipe) is a pipe in which a vertical main pipe is piped. In buildings such as buildings or apartment houses, plumbing works are performed to discharge sewage generated on each floor. The riser pipe for wastewater discharge is piped between the floors.

In general, for structures such as buildings, plate-shaped slabs are installed horizontally. The slab is mainly constructed of concrete, and in a building or apartment building, it becomes the floor and the ceiling at the same time. And before pouring the slab, a through sleeve (Sleeve) is installed in advance at the position where the standing pipe is installed. A through hole is formed in the sleeve at the top and bottom, and the vertical pipe is inserted above and below the sleeve, and the pipe is installed. And the gap of the piped riser pipe is fixed by layer blocking using various fixing members or sealing members. At this time, poor construction occurs depending on the skill level of the operator. For example, it often occurs that the piped riser pipe sags or falls out. Due to this, there was a problem in that the part where the riser pipe was piped was leaking and odor was generated. Therefore, there are problems that require repair work after breaking the wall due to defects after moving in after completion of the building, incurring repair costs, and inconvenience to the occupants.

In addition, during the construction of a building, the height deviation between the floors between the slab that becomes the ceiling and the slab that becomes the floor is about 20 to 50 mm. Due to these inter-floor deviations, in the case of construction after cutting a predetermined length of a riser pipe in advance, the place with a relatively low interfloor height must be cut again on site according to the height of the corresponding floor, and a pipe joint where the interfloor height is relatively high Leakage occurs due to problems such as gaps or missing parts. Moreover, in order to prevent the risk of fire, the use of a cutting machine is prohibited at the site, which causes the inconvenience of custom-manufacturing the standing pipe to the height of each floor, and increases the working time and labor cost. In addition, there was a problem in that the installation height of the drain connector coupled to the riser pipe was not constant due to the variation in the height between floors, making it difficult to slop the pipe and work on the hanger.
