Description

Waterproof step sill with improved construction convenience {WATERPROOF HUMMOCK WITH IMPROVED CONSTRUCTION CONVENIENCE}

The present invention relates to a waterproof stepped to be used for interior construction such as buildings.

Waterproof hummock refers to a structure installed at the end divided by the floor in order to prevent water on the floor from passing to the outside. In residential buildings, waterproof steps are installed in bathrooms and balconies. The waterproof step may be installed at different heights depending on the degree of water accumulating on the floor or the floor finishing material. For example, the waterproof stepped may be installed at a height of about 10 to 20 cm from the floor.

The waterproof stepped may be integrally constructed with the slab to prevent water leakage from a space where water is allowed (eg, inside a balcony) to a space where water is not allowed (eg, indoors). Typically, waterproof steps are installed on the boundary between a living room and a bathroom, a boundary between a balcony and a living room, and a double wall of an underground parking lot. Specifically, in the case of a balcony, the waterproof step installed at the boundary outside the balcony end shall be constructed at a height of about 15 cm, which is a height that can remain at least 10 cm from the finishing layer, taking into account the waterproofing layer of the floor, tile base mortar, and tile attachment. Install handrails of about 120cm in height from the finishing floor of the balcony floor. At this time, a waterproof step is formed by pouring wall concrete at the boundary of the living room, etc., and putting about 15cm into about 12mm from the balcony floor, and then, plastering is performed simultaneously with the waterproofing of the floor.

Typically, waterproof steps are constructed in a wet method. Specifically, after installing the formwork for the construction of the waterproof step, the concrete is poured into the formwork of the waterproof step during the slab concrete pouring process. After laying and installing the waterproof stepped formwork, the waterproof stepped concrete is poured.

However, the above-described wet method has disadvantages of delaying the construction period because construction is cumbersome and inconvenient, and it takes a long time to cure. In addition, there is a problem in that it is difficult to secure excellent construction quality because it is a method of pouring concrete on the waterproof stepped formwork. Therefore, in recent years, there is a trend of active development of dry waterproof chins that are precast and constructed in factories.

Embodiments of the present invention are intended to provide a waterproof stepped with improved construction convenience.
