Description

[0001] WATERPROOFING METHOD FOR THE ROOFTOP [0002]

More particularly, the present invention relates to a waterproof construction method for efficiently discharging rainwater accumulated in roof tops and mortars and moisture in the roof water without a separate induction drainage.

Generally, a roof of a building such as an apartment or the like is constructed with a waterproof structure using a waterproof sheet to prevent penetration of rainwater into the inside of the building.

FIG. 1 shows a roof waterproof structure according to a conventional example in which a waterproof sheet 200, a styrofoam 300 and a protective mortar 400 are sequentially formed on a concrete layer 100 in which reinforcing bars 110 are embedded Can be confirmed.

However, as the building is aged, cracks are generated in the protective mortar 400, and the waterproof sheet 200 is damaged, so that the roof waterproofing can not be effectively performed.

That is, water penetrates into cracks of the protective mortar 400 and water is accumulated in the layer of styrofoam 300, and the protective mortar 400 swells due to the water (including water vapor and moisture) Is generated.

In addition, the water immersed in the water passes through the damaged portion of the waterproof sheet 200 and then flows into the concrete layer 100. The water thus introduced can not be drained through the gutter tube 10, A large amount of fluid flows around the reinforcing bars 110 inside the tub 100 and flows into the room. As a result, a lot of time and cost are consumed due to the repair work.

It is an object of the present invention to provide a waterproof construction method capable of easily discharging rainwater placed inside a waterproof layer on a roof.

In order to accomplish the above object, the present invention provides a method of constructing a building, comprising the steps of: crushing the periphery of an excellent pipe installed on a roof of a building to expose an upper portion of the pipe; A crushed material removing step of removing water and crushing residue from the crushed material; A drain hole forming step of forming a plurality of drain holes in the upper part of the exposing tube exposed in the crushing step; An injection groove forming step of forming a plurality of waterproofing solution injection grooves on the roof surface at predetermined intervals in the radial direction around the guttering position; A waterproofing liquid injecting step of injecting a waterproofing liquid into the waterproofing liquid injecting grooves, injecting a waterproofing liquid sequentially from the waterproofing liquid injection grooves at a distance from the gutter, Forming a protective mortar layer on the waterproof layer; And a finishing step of sequentially forming a primer layer, a middle layer and a coating layer on the surface of the protective mortar layer.

In the present invention, not only the rainwater in the bottom of the roof but also the rainwater in the backward gradient portion can be easily discharged through the waterproofing liquid injection without any separate induction drainage through the excellent observation, Thereby preventing the condensation phenomenon and the bottom swelling phenomenon.

Especially, it prevents the infiltration of indoor space due to leaking water on the roof of the building, which shows an advantage of reducing the repair cost of the building.

In addition, it is possible to reduce the defective cost due to re-leakage by filling the reverse gradient portion caused by the rooftop sagging phenomenon, and to shorten the air shortage and minimize the generation of waste and noise.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, a construction process of a waterproof layer on a roof of a building such as an apartment or a house according to an embodiment of the present invention will be described.

&Lt; Disintegration step > (ST 1)

First, the vicinity of the excellent pipe 10 installed on the roof of the building is crushed.

3, the protective mortar 400, the styrofoam 300, and the waterproof sheet 200 are preferably shredded.

&Lt; Stripping removal step > (ST 2)

Then, the upper end of the gutter tube 10 is exposed at a predetermined height by removing the shredded protective mortar 400, the styrofoam 300, and the waterproof sheet 200 remnants.

At this time, it is preferable to remove the stain adhering to the styrofoam 300 together.

<Drain hole forming step> (ST 3)

As shown in FIGS. 4 and 5, in the drain hole forming step, a plurality of drain holes 11 are formed along the periphery of the exposed portion of the excellent tube 10, .

&Lt; Waterproofing solution injection groove forming step > (ST 4)

6, the waterproofing liquid injecting grooves 410 are formed at regular intervals to the depth of the waterproof sheet 200 exposed to the area of the gutter tube 10 as shown in FIG. 6, .

&Lt; Waterproofing liquid injecting step > (ST 5)

As shown in FIG. 7, the waterproofing liquid injector 500 is used to inject the waterproofing liquid 20 into the waterproofing liquid injecting groove 410 at a high pressure.

Particularly, at this time, the waterproofing liquid 20 is injected at a high pressure by using the waterproofing liquid injector 500 sequentially from the far side of the waterproofing liquid injection grooves 410, so that rainwater in the inside and rainwater in the backward gradient part (b) Is also pushed by the pressure of the waterproofing liquid 20 and is moved to the side of the excellent pipe 10.

FIG. 8 shows that the waterproofing liquid 20 injected at a high pressure is coated on the periphery of the exhaust pipe 10.

&Lt; Protective mortar layer formation step > (ST 6)

Thereafter, the mortar is poured into the crushed area around the gutter tube 10 to form the protective mortar layer 30.

At this time, before forming the protective mortar layer 30, the protective mortar layer 30 is formed on the periphery of the drain hole 11 in a state where the gravel 21 is first buried in the lower part as shown in FIG. 9, It is preferable to form the gap layer so that the guide of the gap can be easily performed.

In order to prevent foreign matter, the gravel 21 to be buried can be formed by coating a Teflon layer 21a on the outer surface as shown in FIG.

In addition, the material for forming such a void layer is not limited to gravel, and various materials such as coarse sand capable of forming voids can be used.

<Finishing step> (ST 7)

Finally, the primer layer 40, the intermediate layer 50, and the coating layer 60 are sequentially formed on the bottom surface of the roof as shown in FIG.

Particularly, at this time, it is preferable that the primer layer 40, the intermediate layer 50, and the coating layer 60 are formed so as to be downwardly sloped about the gutter tube 10 so that the induction of the smoothness can be smoothly performed.

Accordingly, when the construction is completed through the above-described process, the rainwater that has passed through the protective mortar 400 and flows downward is easily guided to the gutter 10, so that the concrete can be prevented from penetrating into the concrete layer 100 So that the corrosion of the reinforcing bar 110 and the indoor inflow phenomenon can be prevented.

12 to 15 illustrate another embodiment of the present invention. In the drain hole forming step ST3, the upper end portion of the exposed vent pipe 10 is cut to a predetermined height, and then a plurality of air holes 11 ' A separate inlet pipe 10a formed on the sidewall is seated and connected to the bottom of the connecting pipe 10a so as to be spaced apart from the outlet pipe 10 by a predetermined distance, A supporting protrusion 13 is provided.

That is, the supporting protrusions 13 are provided at a predetermined interval along the circumference of the connection pipe 10a, so that the inflow grooves 15 can be formed.

The connection pipe 10a and the small diameter pipe 10b are integrally connected to each other at a lower portion of the connection pipe 10a with a small diameter pipe 10b having a reduced diameter so as to be inserted into the expansion pipe 10, And the supporting protrusion 13 is formed in the tapered pipe 10c. The tapered pipe 10c is connected to the tapered pipe 10c.

As shown in FIG. 13, the small-diameter pipe 10b is provided with elastic springs 16 at regular intervals along the circumference so as to stably maintain a constant spacing from the inner wall surface of the gutter tube 10, It is preferable that a spherical guide ball 17 is connected to one end of the spring 16. That is, since the elastic force of the elastic spring 16 prevents the small-diameter tube 10b from being tilted to one side, it is positioned at the center of the excellent tube 10, and thus a predetermined drainage space can be secured in the direction of 360 degrees. Particularly, since the resilient spring 16 is supported by the guide ball 17 without being in direct contact with the inner wall surface of the exhaust pipe 10, damage to the inner wall surface of the exhaust pipe 10 is prevented, The center position can be stably supported.

When the connection pipe 10a is seated in this manner, the fine droplets that have passed through the protective mortar 400 and flowed downward are discharged through the fine inflow grooves 15, (11 ') is formed on the outer peripheral surface of the outer tube (11).

Particularly, when the connection pipe 10a is separately manufactured, replacement work of the connection pipe 10a can be easily performed according to the height change of the roof top floor, thereby reducing the construction cost It is possible to show an advantage that the working efficiency is improved.
