Description

Rooftop waterproofing system and construction method {ROOF WATERPROOF SYSTEM AND CONSTRUCTING METHOD THEREOF}

The present invention relates to a rooftop waterproofing system and a construction method thereof, and in particular, to install a roof covering the entire upper part of the rooftop slab, and to receive water flowing from the roof along an edge between the rooftop slab and the railing wall to guide the drainage. The present invention relates to a rooftop waterproofing system and a method of constructing the rooftop that do not require construction of other laminated structures such as a waterproofing layer and a heat insulating layer.

For example, when constructing a rooftop floor by concrete slab, rainwater, etc., leaks into the building through the rooftop floor, and the rooftop floor is generally waterproofed to prevent such leakage. . This rooftop waterproofing is constructed for the purpose of extending the life of the building by protecting the rooftop slab as well as water leakage. As a waterproofing method, the waterproofing of the coating film, sheet waterproofing, the sheet waterproofing and the waterproofing of the coating film are hard on the floor surface. After the metal 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 heat insulation thereon, and the waterproofing layer is first constructed, and then the waterproofing layer is constructed. Can be.

By the way, in the rooftop waterproofing system as described above, the thickness of the waterproofing layer is as thin as 1 ~ 2mm, shrinkage and expansion as the temperature changes, as well as the thermal expansion coefficient between the waterproofing layer and other laminated structures are different, Cracks in other laminate structures or cracks in the waterproof layer itself damage the waterproof layer, and water damage occurs due to damage of the waterproof layer, causing dissatisfaction of the tenant. Therefore, since the aging or damaged waterproofing layer must be periodically removed and the waterproofing is performed again, a problem arises in that the cost of repairing the building increases over time.

In addition, in the rooftop waterproofing system as described above, if the drying or curing period, etc. are taken into consideration, the construction period of the structure laminated on the rooftop slab takes a lot of time, and there is a problem in that the waterproofing layer and the other laminated structure must 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 inclined roof is installed on the roof railing wall of the building that is built in the heavy snow area, the inclined roof is melted, and the snow accumulated on the inclined roof melts and falls below the building. In the case of use, it is difficult to secure a parking space because 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 is produced and installed easily by the operation of gibbling the drip panel between the roof panel and the wall panel, and generated by the difference in the external and internal temperature by the foam sheet installed on the drip panel. Insulation drip panels of prefabricated buildings have been proposed to prevent condensation and leakage. The Utility Model Registration No. 343195 conventionally gips the drip panel between the roof panel and the wall panel constituting the prefabricated building in order to solve the problem of fixing the drip panel by using a bracket on the upper outer surface of the wall panel. Is solving the safety accidents and condensation in the new sky.

However, the structure of girdering the drip panel between the roof panel and the wall panel proposed in the Utility Model Registration 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 that contain rooftop slabs, ie rooftop waterproofing of apartments.

That is, the structure proposed in the Utility Model Registration No. 343195 has its own structure in which the roof bottom panel has an inclined structure, but the drip panel can be easily installed. However, a typical apartment rooftop includes 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.

The present invention has been made in consideration of the above-mentioned conventional problems, and an object thereof is to install a roof covering the entire upper part of the rooftop slab, and guide water into the drain receiving water flowing from the roof along an edge between the rooftop slab and the railing wall. The present invention provides a rooftop waterproofing system and a construction method thereof that do not require construction of other laminated structures such as a waterproofing layer and a heat insulating layer.

Another object of the present invention is that the components are made of a metal material, there is no fear of damage, the durability is improved, and thus, unlike the existing waterproof system including a waterproof layer, there is no need for periodic maintenance, economical roof waterproof It is to provide a system and its construction method.

Rooftop waterproofing system construction method of the concrete slab structure including a rooftop slab protruding formed along the periphery according to the present invention is a number of incrementally increasing from the railing wall toward the center at a predetermined interval and a certain width The ceummok of vertically installed on the roof slab, and install a plurality of trees on the top of the plurality of seummok with a predetermined width, install a plurality of longitudinal trees at regular intervals orthogonal to the plurality of trees, Constructing a timber support frame lower than the height of the balustrade wall from the ridge located at the center of the upper surface of the rooftop slab toward the balustrade wall; Installing upper and lower support timbers along the inner wall surface of the handrail wall; Arranging a drip tray made of a metal trench to receive water flowing from the roof along the lower support wood and guide the water to the drain hole; Arranging a wall panel along the upper support timber so as to overlap the outer upper end of the drip tray, and fixing the overlapping portion of the drip tray and the wall panel to the lower support timber; Constructing a roof made of a metal material on top of the wooden support frame such that water falls into the drip tray; Putting a handrail cover on an upper end of the handrail wall such that an inner lower end overlaps an upper end of the wall panel, and fixing a portion where the wall panel and the handrail cover overlap each other to the upper support wood; And fixing the top surface of the handrail cover to the top surface of the handrail wall.

According to the rooftop waterproofing system and the construction method thereof according to the present invention configured as described above, the part exposed over the rooftop is completely covered by a metal roof, a drip tray, a wall panel and a railing cover, respectively, and the upper part of the rooftop slab and the handrail wall. Not only do not need to separate the waterproof construction on the inner wall surface of the structure, and there is no need to install a thermal insulation layer or other laminated structure, it is possible to significantly reduce the construction period and construction cost compared to the existing waterproof system including the waterproof layer.

In addition, since the components are made of a metal material, there is no fear of damage, so that durability is improved, and thus, unlike conventional waterproofing systems including a waterproofing layer, there is no need for periodic maintenance, which is economical.

In addition, since rainwater falling on the rooftop or snow melting on the rooftop is prevented from leaking into the building through the rooftop slab or the railing wall, water leakage is prevented, thereby significantly increasing the waterproof performance.

In addition, the snow melts and accumulates on the railing cover in the heavy snow area, which is collected through the wall panel 50 to the drip tray, or flows down through the outer wall of the building so that the water falls freely from the roof to the bottom of the building. Since it does not occur, it is possible to prevent the vehicle from being damaged or to cause injury, thereby making it easy to secure a parking space under the building.

Moreover, the space formed in the lower part of the roof can be used for multi-purpose, and the uppermost floor of the apartment solves the problems caused by the lack of conventional heat insulation due to the heat insulation, windproof, and heat protection effects of the roof.

The features and advantages of the present invention will become more apparent from the following detailed description based on the accompanying drawings. Prior to this, the terms or words used in the present specification and claims are based on the principle that the inventor can appropriately define the concept of terms in order to explain the invention in the best way. It should be interpreted as meanings and concepts corresponding to

1 and 2 show a rooftop waterproofing system according to the present invention.

The rooftop waterproofing system according to the present invention includes a roof 20, a drip tray 40, a wall panel 50, and a railing cover 60.

The roof 20 is supported by the timber support frame 30 so as to cover the entire upper part of the rooftop slab 10, and downward toward the handrail wall 12 based on the widthwise center of the rooftop slab 10. Metal roof panels 22 which are installed to be inclined and metal ridges 24 covering the upper portions of the portions where the metal roof panels 22 meet are provided.

The timber support frame 30 is formed in a lattice structure, a plurality of standing timbers 36 gradually increasing in length toward the central portion from the handrail wall 12 on the upper surface of the rooftop slab 10 at regular intervals. After installing a certain width, and installed a plurality of trees 32 on both sides in the inclined direction on the upper part of the seummok 36, a plurality of trees to support the plurality of trees 32 interconnected 34 intersects a plurality of trees 32 and is installed at regular intervals on the top.

In this case, the lower ends of the plurality of standing wood 36 are constructed by employing well-known methods / structures to be fixed / maintained to the rooftop slab 10. For example, using one or two short supports, attach the middle part of the support to the slab at the bottom of the upright 36, or insert / fix the bottom of the upright 36 at the center. It can be fixed by using a metal fixing cap that can be fixed to the slab by using a nail or the like to protrude the receiving portion and the flange portion extending to the periphery of the receiving portion.

The wooden support frame 30 having a lattice structure for installing the roof panel 22 may be variously modified by those skilled in the art in addition to the above structure / construction method. For example, it is also possible to change the construction order of the tree 32 and the vertical tree 34 for the seummok 36, of course, and in the embodiment of FIG. Regarding it, one longitudinal tree 34 may be added to reinforce the support structure of the entire support frame 30 while fixing the upper end of the tree trunk 32.

Then, by supporting the metal roof panel 22 on the upper portion of the wooden support frame 30, it is possible to form a roof 20 inclined toward the handrail wall 12.

The drip tray 40 is installed along the edge between the rooftop slab 10 and the handrail wall 12, and receives water flowing down from the roof 20 to guide the drain 14. . The drip tray 40 may be formed in a trench type, for example, to receive water flowing down from the roof 20. The drain 14 may be formed in the rooftop slab 10, in which case a drain hole 42 is formed at the bottom of the drip tray 40 to be connected to the drain 14. In addition, although not shown here, the drain hole may be formed in the handrail wall 12, in which case a drain hole is formed in the outer wall surface of the drip tray 40 may be connected to the drain hole formed in the handrail wall 12. have.

The wall panel 50 is disposed on the inner wall surface of the handrail wall 12, the lower end of which covers the outer upper end of the drip tray 40.

The handrail cover 60 covers an upper end of the handrail wall 12, and an inner lower end thereof overlaps an upper end of the wall panel 50.

Therefore, all of the exposed portion of the rooftop is covered by the rooftop waterproofing system of the present invention, that is, the roof 20, the drip tray 40, the wall panel 50 and the handrail cover 60, so that rainwater In addition, water may be prevented from leaking into the building through the roof slab 10 and the handrail wall 12 that melt and snow melts.

According to the present invention, the portion between the drip tray 40 and the wall panel 50 overlaps with the handrail wall 12 and the portion where the wall panel 50 and the handrail cover 60 overlap with the handrail wall. Support woods 70 and 72 are interposed between 12 and 12, respectively. In addition, the overlapping portions of the support wood 70 and 72 are fixed by fixing means 74 such as nails. In addition, the top surface of the handrail cover 60 may be further fixed to the top surface of the handrail wall 12 by fixing means 74 such as nails.

The roof 20, the drip tray 40, the wall panel 50 and the handrail cover 60 are preferably formed of a metal material. In this case, steel sheets or double-coated steel sheets coated on both sides may be used in consideration of corrosion resistance and economic aspects.

In addition, the roof 20 from the top surface of the rooftop slab 10 so that a person can walk over the roof 20 for handling or repair of a rooftop entrance, a water tank, and other rooftop structures protruding above the roof 20. ), The maximum height (that is, the height up to the ridge 24) is preferably a height of the handrail, for example, about 1.2 to 1.5 m or less. Therefore, when the width of the roof 20 is generally 30m, the slope of the roof is gentle inclined so that safety problems do not occur when walking on the roof.

Next, a construction method of the rooftop waterproofing system according to the present invention configured as described above will be described with reference to FIG. 3.

As shown in Figure 1, the wooden support frame 30 is constructed so that the height is lowered toward the handrail wall 12 on the upper surface of the rooftop slab (10).

Next, the support timbers 70 and 72 are arranged in two rows along the inner wall surface of the handrail wall 12 and fixed to the handrail wall 12 with concrete nails. In the case of the lower support timber 70 of the support timbers 70 and 72, as shown in Figure 2 is installed in a structure in which the ladder is laid down, the outer wall surface of the drip tray 40 to be described later does not lift the lower support timber ( 70), it is desirable to be in close contact with / fixed.

Next, the drip tray 40 is disposed along the inner surface of the lower support timber 70. For example, the lower support wood 70 and the height of the drip tray 40 is preferably the same.

Next, the wall panel 50 is disposed along the upper support timber 72 so as to overlap the outer upper end of the drip tray 40, and the portion where the drip tray 40 and the wall panel 50 overlap each other. It is fixed to the lower support wood (70). In this case, it can be fixed simply by fixing means 74, such as a nail, using air tools, such as an air tableting machine. In addition, the inner wall surface of the drip tray (40) can be installed and fixed to the support timber corresponding to the upright timber 36 of the wooden support frame 30 or the lower support timber (70).

Next, the roof 20 is installed on the upper portion of the wooden support frame 30 so that water falls into the drip tray 40.

Next, the handrail cover 60 is placed on the top of the handrail wall 12 so that the inner bottom portion covers the top of the wall panel 50, and the wall panel 50 and the handrail cover 60 are mutually different. The overlapping portions are fixed to the upper support wood 72 by fixing means 74 such as nails.

In addition, the upper surface of the handrail cover 60 may be further fixed to the upper surface of the handrail wall 12 by fixing means 74 such as concrete nails.

According to the rooftop waterproofing system of the present invention configured as described above, the part exposed over the rooftop is completely covered by the roof 20, the drip tray 40, the wall panel 50 and the handrail cover 60 each made of metal. Therefore, it is not necessary to separately waterproof the upper part of the rooftop slab 10 and the inner wall surface of the handrail wall 12, and there is no need to construct a heat insulating layer or other laminated structures.

Since rainwater falling on the rooftop or snow melting on the rooftop can be collected by the roof 20 and the drain 40, it can be drained through the drain 14, so that the rooftop slab 10 or the handrail wall 12 This prevents water from seeping into the building and causing leakage.

In addition, since the snow melts and accumulates on the railing cover 60 in the heavy snow area, the water is collected in the drip tray 40 through the wall panel 50 or flows down the outer wall of the building, so that the water flows from the rooftop to the building. Free fall downward does not occur.

In the embodiment shown in Figure 3, if the roof construction or other processes are made first, wooden support frame installation in consideration of this point, because it is difficult to secure the work space required to proceed to another subsequent process or secure effective waterproof structure, Although it was installed in the order of supporting wood installation, drip tray layout, wall panel installation, roof construction, railing cover installation, the construction sequence can be variously modified by those skilled in the art if the working space is uncomfortable.

For example, it is also possible to perform roof construction first after the installation of the wooden support frame, the installation of the support timber, the drip tray, or the roof construction after the installation of the wooden support frame, the support timber, or the installation of the wooden support frame.
