The present invention relates to a waterproofing and roofing greening system of a roof of a building, and in particular, to provide rooftop waterproofing by installing a double-floor structure using a top panel or the like on the roof, and to realize rooftop greening on a double-floor structure. The present invention relates to a rooftop induction waterproofing system using a rooftop and a rooftop greening structure using the same.

In general, the roof of the building is directly exposed to the outside, and the insulation and the waterproofing material are installed for the insulation and the waterproofing, respectively. In recent years, roof greening is also an important issue for improving urban ecosystem and urban environment.

First, the problem of waterproofing on the roof of a conventional building will be described.

As waterproofing method on the roof of the building, ① asphalt waterproofing method, ② sheet waterproofing method, ③ coating waterproofing method, ④ complex waterproofing method, etc. are widely used, and the types thereof are various as shown in Table 1 below.

As described above, the conventional roof waterproofing method is a method in which a sheet or a coating material is closely adhered to a rooftop floor. Thus, a conventional waterproofing method of forming a new layer on the rooftop floor to prevent water from penetrating into the rooftop floor is performed. Due to the cracking properties and the durability limitations of the waterproofing material itself, it is difficult to realize more effective waterproofing.

In other words, the rooftop close-up waterproofing method as described above, the waterproofing effect due to the aging phenomenon of the waterproofing layer is remarkably degraded over time, and when the waterproofing using the sheet, etc., the sheet will fall off (peel and drop) Particularly, water leakage occurs, and the roofing slab concrete exhibits a problem in that the waterproofing effect is remarkably reduced due to shrinkage expansion behavior due to vibration or temperature change, and various cracks.

TABLE 1

In addition, even if the waterproof construction to a certain degree by the waterproof method as described above, after about 3 to 4 years after the waterproof construction, the waterproof construction must be partially again, and the parts leaked by such repair work It is almost impossible to completely waterproof.

In addition, the conventional roof-floor close contact waterproofing method as described above generally requires the construction of a protective mortar and protective concrete to protect the waterproof layer, so that the air is extended and construction costs also increase.

In addition, the conventional roof-floor close contact waterproofing method as described above, due to the double or triple separated construction or the joint of the waterproofing layer and the thin coating film due to the cracks of the structure body and the protective layer is generated rupture and lifting phenomenon In addition, even when a leakage defect occurs, it is difficult to identify a leaking part due to protective mortar or protective concrete installed on the upper part to protect the waterproof layer.

Next, as for the rooftop greening, the rooftop greening is continuously recommended due to its various advantages in terms of environmental and economical aspects, and it is mandatory to have a rooftop greening facility for buildings of a certain size or larger.

Such rooftop greening provides benefits such as restoration of soil ecosystem, energy saving of heating and cooling, reduction of urban heat island phenomenon, prevention of urban flooding, air purification, water purification, noise reduction effect, improvement of urban landscape, and improvement of durability of buildings.

However, despite the advantages of roof greening, roof roofing may not be activated for a variety of reasons. Among them, defects in the waterproofing layer, high construction cost, and difficulty in maintenance may be the main reasons.

The durability of roofing greening is the most important effect of waterproofing layer and waterproofing layer, which is always moist in the greening space, and planting management such as fertilization and control is done so that it is not affected by microorganisms or chemicals. It is important to form a safe waterproof layer, and considering the characteristics of the planting plan, a barrier layer that protects the waterproof layer and the building from plant roots is an important problem.

If a fault occurs in the waterproofing layer, there is no other method than removing the soil layer and vegetation layer and re-waterproofing, and no matter how perfect the waterproofing method is, there are usually four to five years of durability. When the layers are sufficiently formed, the flowers and fruits of the landscape are in place and the beauty of the beauty is beautiful, the bottom of the waterproof layer will have a problem that must be removed and repaired a lot.

In addition, when a problem occurs in the rooting layer, the waterproofing layer is damaged by the roots of the plant, and cracks are generated on the rooftop floor, which seriously affects the rooftop waterproofing and the floor structure.

In addition, if a rooftop greening facility is used, a waterproofing material having excellent waterproofing performance must be used on the rooftop floor, and a rainproof layer must be formed of a material such as polyethylene foam sheet and polystyrene vinyl on the rooftop. This takes much trouble.

As a result, even if the rooftop greening or the rooftop greening is not realized as described above, the rooftop waterproofing is one of the significant construction elements in the building. As in the related art, the waterproofing layer is simply adhered to the rooftop floor and the rooftop floor is installed. As a method of preventing the water penetrating into the water, there is a limit in realizing a more perfect and efficient waterproofing, especially in the case of the installation of a rooftop greening facility, the problem occurs more.

It is preferable to form the waterproof layer 15 by applying a urethane waterproofing material or an inorganic coating waterproofing material which is usually used as a waterproofing material such as a rooftop to the area leading to the handrail 10.

Therefore, in the rooftop induction waterproofing system of the present invention, the rooftop area of the double bottom structure 20 including the top panel 21 is bounded by the portion where the side panel 60 is installed, and water is discharged through short and long distance drainage channels 40. Waterproofing is made while draining, and the outer region of the side panel 60 is waterproofed by a known coating waterproof layer 15.

As described above, the rooftop induction waterproofing system of the present invention creates an inner space of about 15 cm in height by the top panel 21 and the side panel 60. This interior space allows for easy inspection and simple and permanent maintenance. When the inspection is needed, after opening one upper panel 21, it can be directly and clearly checked while moving freely under the panel by using a remote control vehicle equipped with an endoscope or a small video camera. In addition, it is possible to quickly remove the underlying resources such as damage and blockage of the drain passage 40.

The interior space of the double-floor rooftop waterproofing makes maintenance easier and more convenient. In addition, when heat insulation is required in the inner space, it is also possible to configure by installing a heat insulating material.

Such a reservoir 23 'is preferably formed to have a depth of about 5 ~ 10mm.

Next, referring to the structure in which the heat insulator 80 is added, it is preferable that the installation position of the heat insulator 80 is installed directly under the upper panel 21. At this time, the heat insulator 80 is formed with a hole 81 near the corner to be fitted to the support assembly 27 of the upper panel 21.

Such a heat insulating material 80 may be installed by being fixed to the upper panel 21 by adding a separate support structure or other fixing member, but preferably made in such a way that it is supported and fixed on the upper portion of the short-distance drain passage 41. Can be.

When the heat insulating material 80 is installed inside the double bottom structure 20, it may be performed by assisting not only the flow waterproofing function but also the heat insulating function of the rooftop slab.

Next, the height adjustable structure of the long-distance drainage passage 45 will be described. In the above-described embodiment, the long-distance drainage passage 45 supports the structure through the flow passage support part 34 protruding from the support member 30. Exemplary embodiments of the present invention illustrate a configuration configured to support the drainage passage 45 by using the support pins 34 'installed through the support member 30.

At this time, the upper bar 31 'of the support member 30 has pinholes formed at regular intervals in the vertical direction, so that the height of the long-distance drainage channel can be easily and easily adjusted when the support pin 34' is inserted at a desired position. Can be done.

On the other hand, in the above described only the height adjustment structure of the long-distance drainage passage 45, it is of course also possible to configure to adjust the height of the short-range drainage passage 41 in the same manner.

Since other configuration is the same as the configuration of the above-described embodiment, a description thereof will be omitted.

The rooftop induction waterproof system according to another embodiment of the present invention as described above is formed in a flat structure without a portion where the entire upper surface protrudes, thereby causing problems such as damage to protrusions or hanging on external structures. It does not cause it.

The rooftop double-floor induction waterproofing system and rooftop greening structure using the same according to the present invention configured and operated as described above are not a method of preventing water penetrating into the rooftop as in the prior art by installing a double-floor structure on the rooftop. In addition, since water is naturally drawn to the roof drain hole and discharged, the process of waterproofing facilities can be simplified and construction costs can be greatly reduced. There is an advantage that water can be realized.

In addition, the present invention maintains excellent waterproofing performance even in the case of installing a rooftop greening facility, and has a perfect root structure, and the water, drainage, and fine-grain soil filtration are improved as a whole to provide a better vegetation environment. .

In addition, the present invention not only makes the waterproofing of the rooftop, but also greatly reduces the construction cost of the roofing planting facility, and also allows semi-permanent maintenance by allowing the maintenance to be carried out using the internal space of the double floor structure after construction. The durability of the waterproof layer is increased, and there is an advantage of ensuring optimal conditions for roofing greening.
