Description

Drains to prevent falling-off of waterproof coating}

The present invention forms a waterproofing connection laterally at a position spaced from the top of the side wall of the drain to the bottom, so that the end of the waterproofing film seated on the upper surface of the waterproofing connection is pressed by the press mortar from the top to firmly strengthen the waterproofing film on the outside of the drain. This is about a drain that prevents the waterproofing of the coating film from falling off while being fixed and making it easy to install the drain and waterproofing film.

In spaces where water is used, such as the bathroom or laundry room of an apartment complex, a drainage system is installed on the floor to discharge sewage.

The drainage device (2) is embedded in the floor (1), and includes a drain (5) coupled to communicate with the drain pipe (3), a drain cover (4) covering the top of the drain (5), and the drain cover (4). ) a water collection plate (6) inserted in the center of the water collection plate (6) to collect sewage, a drainage trap (7) inserted in the center of the water collection plate (6) and provided with a deodorizing water tank (71) and a deodorizing pipe (72), It consists of a drainage grill (8) covering the upper part of the water collection plate (6) (Figure 1).

This drainage device is constructed by installing a drain buried in the floor, constructing a waterproofing film on the upper surface of the floor so that it is in contact with the drain, pouring tile mortar on top of the waterproofing film layer, and installing tiles.

At this time, urethane material is mainly used for coating waterproofing, and PP (polypropylene) material is mainly used for drain. However, urethane does not adhere to PP, so there is a problem that water leakage occurs at the joint between the waterproof coating and the drain.

Accordingly, in order to prevent water leakage that occurs at the joint between the waterproofing film and the drain, as shown in Figure 1, when constructing the waterproofing film, the waterproofing film is raised to the top of the side wall of the drain and then rolled down to the inside of the side wall to fix the waterproofing film.

However, the winding down work of film waterproofing is not easy to construct, so it is often missed on site.

In addition, when attaching the drain cover to the top of the drain, the fitting pipe 41 protruding from the bottom of the drain cover must be fitted and coupled to the inside of the drain. However, it is not easy to join the drain cover due to the interference of the waterproof film rolled down on the inside of the side wall, and in the process of joining these members, the waterproof film is damaged and defects often occur.
