Description

A waterproof device for pipelines passing through floor slabs

technical field

The utility model relates to a waterproof device for pipelines passing through floor slabs, which belongs to the field of building construction. the

Background technique

The buried pipes through the floor are buried before concrete pouring. Due to the change of temperature, or because the concrete has a process of expansion and contraction during the hydration reaction process, there is a gap between the pipes through the floor and the floor, resulting in water leakage in the house. phenomenon occurs. the

Contents of the invention

In order to solve the above technical problems, the utility model provides a waterproof device for the through-floor pipeline, which has good water resistance and construction performance, and can prevent the floor from leaking when the through-floor pipeline passes through the floor. the

The technical solution provided by the present invention is to provide a waterproof device for the pipeline through the floor. At the interface between the pipeline through the floor (6) and the floor (7), a waterproof coiled material (2) with a corner that can slide freely horizontally is provided. The upper end of the waterproof coiled material is The part is turned up and the end is sealed; the waterproof membrane (2) is provided with waterproof mortar (3); the water-stop ring (1) is set in the middle of the floor (7), and the water-stop ring (1) is set on the floor-penetrating pipe (6 ); set the upper seal (4) at the interface between the floor-through pipe (6) and the mortar leveling layer (8) and the ground surface layer (9); set the lower seal (4) at the interface between the floor-through pipe (6) and the lower end of the floor (7) seal (5).

Further, the water stop ring (1) is an annular water-swellable rubber ring, which is glued and connected with the pipeline (6) passing through the floor.

Further, the waterproof roll (2) is an APP waterproof roll.

Further, the upper seal (4) provided at the interface of the ground surface layer is polyurethane sealant.

Further, the lower seal (5) provided at the interface between the floor-through pipe (6) and the lower end of the floor (7) is silicone sealant.

The beneficial effect of the invention is that it has good water resistance and constructability, and can prevent the floor from leaking when the floor-through-slab pipe passes through the floor.

Detailed ways

As shown in Figure 1, the sewer pipe was pre-embedded during the construction of the kitchen and bathroom in a residential building. The sewer pipe belongs to the floor-penetrating pipe, and the floor-penetrating waterproof device is used to ensure that the kitchen and bathroom will not leak after one-time construction. The specific method is that a waterproof coiled material 2 with a corner that can slide freely horizontally is provided at the interface of the floor-through pipe 6 and the floor 7, the upper part of the waterproof coiled material is turned back, and the end is sealed; the waterproof coiled material 2 is provided with a waterproof mortar 3; A water-stop ring 1 is set in the middle of the floor 7, and the water-stop ring 1 is set on the floor-through pipe 6; an upper seal 4 is provided at the interface between the floor-through pipe 6 and the mortar leveling layer 8 and the ground surface layer 9; A lower seal 5 is arranged at the lower end interface of the floor 7 . The water stop ring 1 is an annular water-swellable rubber ring, which is glued and connected with the pipeline 6 passing through the floor. Waterproof membrane 2 is APP waterproof membrane. The upper seal 4 provided at the interface between the sealing facility 3 and the ground surface layer is polyurethane sealant. The lower seal 5 provided at the interface between the floor-through pipe 6 and the lower end of the floor 7 is a silicone rubber sealant. the

Before laying floor tiles, use silicone glue to seal the gap between the pipe and the floor concrete at the interface between the floor pipe and the floor opening, and make a rounded corner before installing a waterproof membrane, using APP membrane, on the ground It is fully paved and pasted, only at a distance of 200 mm from the pipe, the coiled material between the floor and the pipe is not only not paved, but also a coiled material sliding layer and waterproof mortar are set between the concrete structure layer on the floor and the APP coiled material , and set polyurethane sealant at the interface between the floor-through pipe and the mortar leveling layer and the ground surface layer, and set silicone sealant at the interface between the floor-through pipe and the lower opening of the floor to form a waterproof device for the through-floor pipe. the
