Description

Rooftop Improvement Structure and Manufacturing Method of the Structure

The present invention relates to a rooftop improvement structure and a construction method thereof, and in particular, a separate channel passage is installed in a rooftop slab, and a steel structure and a roof installed on an upper portion of the roof structure are provided to have an inner space that allows passage of a passenger easily. The present invention relates to a roof improvement structure and a construction method thereof, which are easy to evacuate in case of emergency as well as waterproofing the rooftop, and are always easy to be repaired.

For example, when constructing a rooftop floor by a concrete slab, rainwater and the like leak through the rooftop floor. In order to prevent such leakage phenomenon, the rooftop is generally waterproofed. Figure 1a shows a cross-sectional perspective view of a conventional concrete slab structure. As shown in Figure 1a, it can be seen that the upper surface of the roof 10 is provided with a concrete slab 30, the edge portion is surrounded by a handrail wall (20).

This rooftop waterproofing is constructed for the purpose of extending the life of the building by protecting the rooftop slab as well as blocking the leakage. As a waterproofing method, the waterproofing of the coating film, the sheet waterproofing, the sheet waterproofing and the waterproofing of the coating film are hard metals on the floor surface. After the sheet is installed, various waterproofing methods such as composite waterproofing may be applied to the surface of the hard metal sheet. On the other hand, in order to prevent water from pooling on the roof, a loop drain capable of collecting and draining water is provided in the roof drain.

In this case, the roof drain should be constructed so that water does not penetrate between the roof drain and the waterproof layer and leak into the building. An example of such a waterproof structure and a loop drain are disclosed in Korean Patent No. 171704 and the like.

The waterproofing layer is generally installed on the upper surface of the rooftop slab, and a protective mortar layer, a thermal insulation layer, a pressing layer, etc. may be laminated to protect the waterproofing layer and to insulate it thereon, and the waterproofing layer may be constructed first, and then the waterproofing layer may be constructed. Can be.

By the way, in the conventional rooftop waterproofing structure, the thickness of the waterproofing layer is as thin as 1 ~ 2mm, the shrinkage and expansion is repeated as the temperature changes, as well as the thermal expansion coefficient of the waterproofing layer and other laminated structure is different, so that the other laminated structure The cracks of the cracks or the cracks of the waterproof layer itself damages the waterproof layer, and the damage of the waterproof layer occurs, causing the tenant's dissatisfaction. Therefore, since the aging or damaged waterproofing layer must be periodically removed and the waterproofing is performed again, there arises a problem that the repair cost of the building increases with time.

In addition, the above-described prior art takes a lot of construction period of the structure laminated on the rooftop slab in consideration of drying or curing period, and also has a problem that the waterproofing layer and other laminated structure should also be constructed on the handrail wall.

On the other hand, the inclined roof can be provided along the top of the handrail wall for the purpose of not waterproofing the handrail wall, this example is disclosed in Korean Patent Laid-Open No. 2004-9509.

However, when the slope roof is installed on the roof railing wall of a building constructed in a heavy snow area, the slope roof is installed, and the snow accumulated on the slope roof melts and falls below the building, which is used as a parking lot. In this case, it is difficult to secure a parking space because there is a possibility that the parked vehicle may be damaged, and it may occur even if human life is avoided.

In addition, in the case of newly repairing the inclined roof on the roof railing wall of the existing building, there is a problem in that the construction cost increases because it is necessary to install the formwork, etc., in order to prevent safety problems and to prevent such problems.

In addition, in a conventional apartment or the like, the top layer is cold in winter due to lack of heat insulation, and there is a hot structural problem in summer, so it is necessary to provide a thick insulation layer.

On the other hand, Utility Model Registration No. 343195 has a condensation phenomenon caused by the temperature difference between the outside and the inside of the foam panel installed on the drip panel is easy to manufacture and install by the operation of gibbling the drip panel between the roof panel and the wall panel. Insulation drip panels in prefabricated buildings have been proposed to prevent leakage. Utility Model Registration No. 343195 has conventionally stowed a drip panel between a roof panel and a wall panel constituting a prefabricated building in order to solve the problem of fixing a drip panel using a bracket on the top outer surface of a wall panel. This solves construction safety accidents and condensation.

However, the structure of girdering the drip panel between the roof panel and the wall panel proposed in Utility Model No. 343195 is effective to clean up the rainwater of a small prefabricated building, but the balustrade walls protrude along the periphery. It is not applicable to large concrete slab structures containing rooftop slabs, ie rooftop waterproofing of apartments.

That is, the structure proposed in Utility Model Registration No. 343195 can be easily installed because the roof bottom panel has its own inclined structure, but a typical apartment rooftop has such a sloped roof bottom panel. It is not applicable because it is not. Furthermore, Utility Model Registration No. 343195 mentioned above does not make any proposal for waterproofing the rooftop of an apartment.

In addition, Patent No. 0887020 provides a roof 10 covering the entire rooftop slab 30 and receives water flowing from the roof along an edge between the rooftop slab 30 and the handrail wall 20 to drain. By providing the guide drip tray 50, the rooftop waterproof structure which does not require the construction of other laminated structures, such as a heat insulation layer, with respect to the rooftop 10 is disclosed. 1B illustrates a front view of a rooftop waterproof structure in which a roof 200 covering an entire rooftop slab is installed.

However, Korean Patent No. 0887020 uses a finishing material using wood in the lower part of the roof 200, and there is a problem that it is difficult to reinforce the passage and further reinforcement in the lower part of the roof 200 due to the small gap between the vertical wood 60 and the wood. have. In addition, the structure is formed of wood there is a risk of asphyxiation due to smoke, such as carbon dioxide inside the roof in case of fire. In addition, a separate passage is not installed in case of an emergency, and there is a problem that difficulty occurs when escaping to the outdoors because the passage is not easy under the roof 200.

Therefore, the present invention was devised to solve the above problems, according to the rooftop improvement structure according to an embodiment of the present invention is provided with a support column and a roof support as a steel frame structure in the lower part of the roof, separate to the rooftop slab By installing a waterway, the rooftop does not require the construction of other laminated structures such as a waterproof layer and a thermal insulation layer, and it is possible to quickly cope with emergencies such as fire and safety as well as waterproofing and easy repair and repair. To provide a waterproof structure and its construction method.
