Description

Drainage device for leakage of rooftop floor and construction method using same

The present invention relates to a drainage prevention device for a rooftop floor and a construction method using the same, and in particular, when deposition water is generated due to dew condensation inside a rooftop of a building, the discharged water may be efficiently discharged to prevent a phenomenon of leakage. The present invention relates to a drainage preventing device for rooftop flooring and a construction method using the same.

In general, as shown in Figure 1, the roof of the building is a slab construction of concrete, such as waterproofing such as asphalt waterproof or sheet waterproofing on it, and then heat-insulated construction with a heat insulating material (11), Do protective concrete construction as a rooftop on the top.

In the case of the roof of the building, the heat insulating material 11 mainly uses a foamable heat insulating material such as styrofoam. Such a heat insulating material is a kind of a foamable resin and has hygroscopicity containing moisture.

In the case of the roof or the roof of the building, the water generated by rain or snow (hereinafter referred to as immersion water) is not all drained and removed, but some are seeped into the concrete and insulation inside the rooftop.

As a result, as the amount of water soaked increases over time, cracks are generated on the rooftop floor, causing corrosion, and in winter, it freezes to promote freezing and cracking.

If these cracks are left on the roof or roof of the building, it will pass through the steps of seepage of the sediment into the rooftop and cause water leakage, resulting in shortening the life of the building.

In order to prevent cracks and water leakage of the roof of the building, floor repair work is performed. In the floor repair work, it is common to repair and waterproof the floor with an exposed waterproof system, such as urethane work.

In addition, since the floor of the slab is constructed with a waterproofing material from the time of building, cracks are generated due to a long time, and the sedimented water penetrates into the generated cracks.

On the other hand, the cause of the deposition is that the indoor temperature inside the building in winter is maintained above 26 ℃ due to heating, and the outdoor temperature on the roof surface of the building is measured below the average minus 10 ℃, the temperature difference between indoor and outdoor In general, when the outside temperature is below 5 ° C and the relative humidity inside the building is in the range of 60 to 90%, deposition water occurs due to condensation between the reinforcing materials 10 laminated on the rooftop. Done.

As such, even when the sedimentation water is generated inside the rooftop of the building, a leak prevention drainage device must be installed so that the sedimentation water can be drained without accumulation of the sedimentation water inside the building. As shown, the sedimentation water once formed by the airtight treatment around the drain pipe through the concrete to prevent the backflow of the drainage during the initial construction is formed into a structure that can not be discharged and leaks inside the building due to the accumulation of sediment water There was a problem.

The present invention relates to a drainage prevention device for a rooftop floor to solve the above problems, and a construction method using the same, in particular, when the deposition water occurs due to condensation inside the rooftop floor of a building to efficiently discharge the water leakage occurs It aims at making it possible to prevent a phenomenon.

The present invention includes a concrete crushing step of crushing concrete poured into the heat insulating material of the reinforcement laminated on the roof of the building at the same time is inserted into the drainage structure of the double structure of the reinforcement laminated on the roof of the building; A drain member inserting step of inserting a drain member having a dual structure into the heat insulating material after the concrete is crushed in the concrete crushing step; A first laminating step of forming a gravel layer having a predetermined height on the drain member after inserting the drain member in the drain member insertion step; A second laminating step of providing a nonwoven fabric on the gravel layer in the first laminating step; It consists of a third stacking step of applying a protective mortar on the gravel layer of the first stacking step and the nonwoven fabric of the second stacking step to achieve a reverse flow prevention and discharge of the sedimentation water generated between the reinforcing material.

As described above, the present invention prevents leakage of the interior of the building by efficiently discharging the sediment generated by the condensation through the drainage member, thereby reducing the anxiety of the defect repair work and preventing the occurrence of the leakage by a simple device and construction method. It is an invention that is effective in maximizing efficiency by minimizing work convenience and minimizing construction period and construction cost.
