Rooftop waterproof structure with moisture and debris removal function {STRUCTURE OF COMPOUND ROOF WATERPROOF}

The present invention relates to a waterproof structure of a rooftop, and more particularly, to remove moisture and solids that can quickly and efficiently remove moisture or solids generated between the rooftop slab and the waterproofing layer formed on the rooftop slab. It relates to a waterproof roof structure provided.

Generally, a waterproof layer is formed on the roof slab of a concrete building to prevent leakage, but moisture is generated between the rooftop slab and the waterproof layer due to the temperature difference according to the seasonal temperature change and the day and night temperature change, or the water is accumulated. As such, moisture or solids generated by natural phenomena affect concrete building structures, causing repeated contraction and expansion, causing cracks not only to rooftop slabs but also to the waterproofing layer, and also to the phenomenon of lifting or swelling of the waterproofing layer. Done.

Therefore, rainwater penetrates into the interior of the structure through the cracked areas of the rooftop slab and the waterproofing layer, shortening the life of the entire structure, and also occurs between the rooftop slab and the waterproofing layer. There is an urgent need for a method for quickly removing moisture or solids, which has been proposed in the past.

That is, FIGS. 1 to 3 show a conventional waterproof structure in which a means for removing moisture or solids generated between the rooftop slab and the waterproof layer is provided, and the waterproof layer is usually the lowest formed on the rooftop slab 1. By forming the first waterproof layer 2, the intermediate second waterproof layer 3 formed on the first waterproof layer 2, and the best third waterproof layer 4 formed on the second waterproof layer 3 in that order. do.

The waterproof layer is, for example, the first waterproof layer (2) is a mortar waterproofing agent mixed with a waterproofing mortar, the second waterproof layer (3) is a protective mortar made of mortar, the third waterproof layer (4) is made of a waterproof coating made of urethane In addition, other similar materials may be substituted, and a heat insulating member such as styrofoam may be interposed between the first waterproof layer 2 and the second waterproof layer 3, although not shown.

In such a waterproof structure, moisture and solid matter generated due to temperature differences due to changes in the external environment are formed on the first waterproof layer 2 and the first waterproof layer 2 of the mortar waterproofing agent formed on the rooftop slab 1. It is generated between the second waterproof layer 3 of the protective mortar formed in the configuration, and the structure for removing the moisture or stagnate, as shown in Figure 1 and 2, the entire rooftop on the bottom surface of the second waterproof layer (3) A lattice-shaped solid waste induction passage 3a is formed over an area, and at each intersection of the solid waste induction passage 3a, the second and third waterproof layers 3 and 4 pass through the solid waste induction passage 3a. The air distribution pipe (5) is installed upright so that and the outside communicate with each other.

At this time, the surface of the first waterproof layer (2) gives a gradient so that the solid matter is guided to the solid matter induction passage (3a), the rain barrier cap (5a) to prevent the rainwater penetrates into the upper end of the air distribution pipe (5) This is installed. 1 and 3, the rainwater on the third waterproofing layer 4 penetrates through the first to third waterproofing layers 2, 3, and 4 and is connected to the main drain 6 of the rooftop slab 1.

It is possible to remove the moisture existing between the and the second waterproof layer.

However, this conventional configuration, when the difference in air pressure or temperature difference between the outside and the solid matter induction passage (3a) according to the change of the external environment, the flow of air circulated to the solid matter induction passage (3a) smoothly It does not have the disadvantage that the removal efficiency of the moisture or solids can not be removed quickly because the moisture or solids removal efficiency is lowered.

In addition, since the flow pressure of the air through each air flow pipe 5 distributed over the entire rooftop area is different, some air flow pipes 5 smoothly flow the air, and some air flow pipes 5 As the phenomenon of no air flow occurs, moisture or solid matter in the area where no air flows is not removed. Furthermore, since the efficiency of removing moisture and solid matter is further reduced in the rainy season, air naturally generated in the solid waste induction passage There was a problem that the flow alone was difficult to remove quickly.

For the purpose of this, the surface of the first waterproof layer 12 forms a gradient so that the solids can be guided to the solid waste induction passage 13a, and the solid waste induction passage 13a is formed in a lattice shape over the entire rooftop area. Preferably, on the solid water induction passage 13a, preferably at each intersection where the solid water induction passage 13a intersects, the second and third waterproof layers 14 pass through the solid water induction passage 13a. An air distribution pipe 15 is installed so that the outside and the outside communicate with each other, the rain barrier cap 15a is installed on the upper end of the air distribution pipe 15 so that rain does not penetrate into the inside.

In addition, the air forced supply pipe 16 for connecting the solid matter induction passage 13a to the outside is connected to one end of the solid matter induction passage 13a, and the blower 17 is connected to the outer end of the air forced supply pipe 16. ) Is installed so that the outside air can be artificially supplied to the solid waste induction passage (13a) by the blower (17).

In the present embodiment, the air forced supply pipe 16 and the blower 17 are respectively provided at one end of the solid waste induction passage 13a formed long in the left and right directions in FIG. 4, but are not limited thereto. It may be provided in one end of the solidification guide passage 13a in another direction (up and down direction in FIG. 4).

In addition, the water pool guide passage (13a) is formed with a water pool groove portion (12a) lower than the bottom of the water pool guide passage (13a). On the bite groove portion 12a, a transparent cylinder 18 having an upper portion penetrated through the second and third waterproof layers 13 and 14 and exposed to the outside is installed, and a lower portion of the transparent cylinder 18 is opened to float therein. The member 19 is provided. The floating member 19 is installed in the transparent cylinder 18 in a long vertical direction, the lower end of which is located in the water recess groove 12a, and the upper end of which is located above the transparent cylinder 18. For example, it can be configured in a hollow configuration.

Therefore, when the stiff water in the bite groove portion (12a), the floating member 19 rises, so by visually confirming the change in the height of the upper surface of the floating member 19 through the transparent cylinder 18 exposed to the outside The administrator can tell if it exists.

On the other hand, the present invention, as shown in Figure 4 and 7 is provided with a solid waste discharge passage (13b) connecting the main drain hole 21 and the solid waste induction passage (13a) provided in the roof slab (11). do. The solid waste discharge passage (13b) is formed on the bottom surface of the second waterproof layer 13, similar to the solid waste induction passage (13a), it is preferable to connect from the intersection of the solid waste induction passage (13a) as shown in FIG. Do.

In addition, the main drain port 21 of the roof slab 11 is provided with first and second drain cylinders 22 and 26 having a double structure. The first drain cylinder 22 is composed of an outer cylinder 23 and an inner cylinder 24, and forms a solid waste discharge hole 25 between the outer cylinder 23 and the inner cylinder 24.

In this case, when the blower 17 installed at one end of the solid water induction passage 13a is driven to strongly supply the external air to the solid water induction passage 13a through the air forced supply pipe 16, the solid water induction passage 13a. ), Strong air flow is generated to quickly remove moisture or contaminants, and the supplied air is exhausted to the outside through the air distribution pipe 15.

In addition, although the present invention may drive the blower 17 for artificially forcibly supplying air in anticipation of the occurrence of moisture or solid matter, it is inefficient to waste power when moisture or solid water does not exist. Can be operated. Therefore, as shown in FIG. 6, the upper end of the floating member 19 installed in the transparent cylinder 18 exposed to the outside can be observed to confirm the presence or absence of solids, and then the blower 17 can be efficiently operated.

That is, the solid water guided by the solid water induction passage 13a flows into the water pool groove 12a lower than the bottom of the solid water induction passage 13a, and the water level rises, and the floating member 19 floats by the level. . Therefore, the manager can directly check the presence of the solids by directly seeing the height change of the floating member 19 through the transparent cylinder 18, and selectively drives the blower 17 according to the presence of the solids.

In addition, according to the present invention, as shown in FIGS. 4 and 7, the solid waste induced in the solid waste induction passage 13a is connected to the main drain hole 21 of the rooftop slab 11 connected thereto through the solid waste discharge passage 13b. Since it is discharged, the removal efficiency of the solids is further increased.

Then, the solid matter flowing from the solid waste induction passage 13a to the solid waste discharge passage 13b is discharged to the main drain 21 through the solid waste discharge hole 25 of the first drain cylinder 22. Rainwater is discharged to the main drain 21 through the second drainage cylinder 26, and rainwater falling into the second drainage cylinder 26 by the inner cylinder 24 of the first drainage cylinder 22. It can be prevented from flowing back into the discharge passage (13b).

Further, when the second drain cylinder 26 and the inner cylinder 24 of the first drain cylinder 22 are screwed together, the total height is always formed when the first to third waterproof layers 12, 13, and 14 are formed. It is not constant, and the installation height of the second drain cylinder 26 can be adjusted in response to the change in the overall height of the first to third waterproof layers 12, 13 and 14, thereby improving the workability.
