Description

Roof leakage prevention structure and leakage prevention method through incision

The present invention relates to a rooftop leak prevention method through incision, and more specifically, the rainwater that penetrates the waterproof sheet due to various reasons on the rooftop is rolled up all the existing waterproof layers during waterproofing work due to leakage caused by drainage or drying. The present invention relates to a rooftop leak prevention structure and a leak prevention method through an incision that is cheaper than the cost of reconstruction and can be used semi-permanently because only the leaked place is found to prevent the removal and leakage of the deceased person.

In general, the rooftop slabs of concrete buildings generate moisture or decay due to rain or snow, or temperature differences due to seasonal temperature changes and day and night temperature changes. By repeating expansion for a long time, it causes cracks and shortens the life of the whole structure, and rainwater penetrates into the interior through cracks, resulting in troublesome maintenance and cost due to maintenance work to prevent this. Moisture or standing water should be removed quickly.

The prior art for removing moisture and rainwater on the roof bottom surface is disclosed in Korean Patent Publication No. 10-2005-0122984.

The moisture drying system inside the roof top of the building discharges moisture accumulated in the insulation layer of the roof of the building or the concrete inside the roof using the water removal system, and then, in order to maintain the drying state, It is configured to remove the moisture inside the floor by making the grooves into the groove by the moisture that is permeated inside the rooftop by making a groove.

However, the conventional moisture drying system inside the rooftop of a building is configured not only to remove the moisture and moisture that penetrates the entire rooftop floor, but also to remove only the moisture and moisture that penetrates the interior of the insulation so that the complete moisture and moisture of the rooftop floor can be eliminated. There is a problem that cannot be removed.

In addition, the moisture drying system inside the rooftop floor does not remove the moisture that penetrates the interior of the upper concrete or floor surface, causing additional rooftop leakage and cracking.

As a prior art document to solve the above problems, the "roof waterproof construction method" of Korean Patent Publication No. 10-1732099 (2047.05.04.) Is a slab surface treatment step of removing contaminants adhered to the concrete slab surface; ; A blow groove forming step of forming a main inlet blow groove, forming a main blow groove, forming a supply blow groove, forming a branch blow groove, and forming a discharge blow groove; A blower pipe installation step consisting of a main inlet blower pipe installation process, a main blower pipe installation process, a hot air accelerator member installation process, a supply air blower pipe installation process, a branch air blower pipe installation process, and a discharge air blower pipe installation process; A forced hot air spraying step of installing hot air means to inject air or hot air into the main inlet blower pipe to remove moisture and moisture in the bottom surface of the slab; Waterproof coating coating step of forming a waterproof coating by sequentially applying a top coat, a middle coat, a top coat on the upper surface of the slab (10); Waterproofing film drying step of completing the drying of the waterproofing film by natural drying; It is characterized in that it comprises a blocking cover installation step of preventing the penetration of water into the slab by installing a rain cover in the rain during each step.

However, the rooftop waterproof construction method is very difficult to repair when a defect is issued in a state in which the construction is completed, and there is a problem in that the construction of the waterproofing layer needs to be carried out again.

In addition, there is a problem in that maintenance costs are additionally generated because electricity for operating the hot air means must be used when removing moisture and moisture into the main inlet air flow pipe by using the hot air means in rainy weather.
