Such a watertight jaw can be integrally formed with the slab to prevent the leakage of water into the watertight space, and is usually installed between the living room and the bathroom or balcony, the double wall of the underground parking lot, and the like.

For example, in the case of a balcony, the waterproof jaw facing the outside of the balcony end is constructed to a height of 15 cm, which is more than 10 cm from the finish layer in consideration of the bottom waterproof layer, tile mortar and tile attachment , And a handrail having a height of about 120 cm from the floor bottom of the balcony is installed on the upper side thereof. At this time, the place facing the inside of the living room, etc., is putting the concrete wall of the balcony into the floor of about 15cm from the floor of the balcony to form a waterproof jaw.

1 is a cross-sectional view showing a waterproofing jaw formed between a living room or a bedroom and a bathroom or a balcony according to a conventional technique.

Referring to FIG. 1, it can be seen that a waterproof jaw 13 is installed between a living room or a bedroom 11 and a bathroom or a balcony 12.

The waterproofing jaws according to the prior art are typically constructed in a wet manner. In other words, after installing the waterproof jaw formwork, the concrete is placed in the waterproof jaw formwork in the slab concrete casting process, or after the slab construction is completed, the waterproof jaw reinforcement is horizontally surveyed and the waterproof jaw formwork After installation, waterproof jaw concrete is installed in a manner to put it.

However, the above-mentioned wet type method is disadvantageous in that the construction is very cumbersome and inconvenient, and it takes a long time to cure, thereby delaying the construction period. In addition, there is a problem in that it is difficult to secure an excellent construction quality because the concrete is laid in the waterproof jaw formwork.

As a prior art for solving the problem of the above-mentioned wet type waterproof jaw, Korean Patent No. 10-1090674 discloses an invention named "construction of dry waterproof jaw" do.

2 is a cross-sectional view showing a dry waterproofing jaw according to a conventional technique.
