The present invention relates to a greenery landscaping waterproof structure, and more particularly, to a rooftop greenery landscaping waterproof structure and waterproofing method using EPDM rubber waterproof sheet.

As civilization develops, many tall buildings are built in urban areas, forming a forest of buildings. Therefore, in order to make a green space in the center of the city, green landscaping works are carried out on the roof of a large building. Elements of the greenery landscaping basically include a bench and a walkway, etc. Here, a vegetation such as a shrub is made, and lighting, sculptures, ponds, and fountains are formed. Therefore, the rooftop drainage and watering facilities are required for the greenery landscaping, and the rooftop waterproofing work should be basically performed.

In general, the waterproof structure and the waterproofing method applied to the waterproofing of the roof of the building structure or the upper part of the underground parking lot, the solid material of solid brown asphalt, asphalt felt, asphalt roofing obtained from the petrochemical series, Asphalt 3-ply 8-layer waterproof structure and waterproofing method which heat-melt brown asphalt to high temperature and carry out laminated construction were used. Since the asphalt 3-layer 8-layer waterproof structure is a multi-layer construction, the coating layer of the waterproof layer is relatively thick, so that the waterproof effect is excellent, and the durability and watertightness are excellent. At the same time, the work process is complicated due to the multi-layer construction, special construction skills are required, and labor costs are high, and there is a high risk of burn accident of workers due to high temperature heating work, and environmental pollution caused by smoke and odor are serious. Do. In addition, the above method is liable to lift the joint portion and the adhesive portion, and is susceptible to changes in temperature, and thus easily cracks the waterproof layer at low temperatures.

In order to solve the disadvantages of the conventional three-layer, eight-layer waterproof structure of the asphalt, a high-adhesive rubberized asphalt compound is coated on both sides with a uniform thickness, using synthetic resins such as polyester nonwoven fabric or polypropylene (PP) woven fabric as the center. After that, a polyethylene film is attached to the upper surface, and a release method (silicone coated paper) is attached to the lower surface to apply a waterproofing method using a roll-type asphalt waterproof sheet made to have self adhesive force. However, the properties of materials such as synthetic resins and rubberized asphalt used in the waterproofing method are easy to age due to low UV resistance and ozone resistance, low cold resistance and high possibility of water leakage at low temperatures in winter. When water accumulates and contacts water, carcinogens such as tar are discharged. In addition, even when using the asphalt waterproof sheet to form a layer of two layers in order to increase the waterproof effect, the joint is easy to leak due to temperature changes and structure cracks, moreover the jaw is formed It can be a barrier to walking.

Specifically, FIG. 1 is a cross-sectional view of a typical rooftop greenery landscaping waterproof structure of a typical building. After bonding the first asphalt waterproof sheet 20 to the rooftop concrete slab 10, the first asphalt waterproofing is performed. The second asphalt waterproof sheet 24 is bonded to the top of the sheet 20 in the horizontal or vertical direction. In addition, in order to insulate the outside, a heat insulating material 22 for blocking heat inside and outside the building may be formed under the first asphalt waterproof sheet 20. Therefore, the double structure in which the asphalt waterproof sheets 20 and 24 are directly attached is damaged when one waterproof sheet is damaged, and thus the remaining waterproof sheets are damaged in contact with each other. This becomes difficult. Therefore, when the waterproof sheets 20 and 24 as the waterproof layer are destroyed, not only the waterproof effect is reduced, but also moisture such as rainwater penetrates into the thermal insulator 22 to reduce the thermal effect. In addition, since a plurality of four-ply bonded protrusions 26 are formed due to the bonding portion of the first asphalt waterproof sheet 20 and the bonding portion of the second asphalt waterproof sheet 24, the waterproof layers 20 and 24 are placed in a protective mortar or the like. If it is exposed to the outside immediately, it acts as an obstacle such as getting foot when walking.

In addition, a moisture retarder (not shown) may be formed under the heat insulating material 22 to prevent moisture contained in the building structure from penetrating into the heat insulating material 22. As the moisture retardant, a vinyl or film material is generally used, which has a disadvantage in that it does not flexibly cope with behavior due to vibration or temperature change of the structure. In addition, since the building, which is a concrete structure, contains moisture by itself due to landscaping work and rainwater, such as vegetation, an air vent is installed on the roof of the building to separate the moisture retardant. 2A and 2B are cross-sectional views of a typical greenery landscape waterproofing structure on a rooftop of a building each having an air vent. As shown in FIG. 2A, the air vent 60 thickens a fixing portion 62 in contact with concrete. It is directly coupled to the structure via a separate fixing means 64. In addition, when the said air vent 60 is not provided, as shown in FIG. 2B, the air inlet part 66 is formed in the rooftop floor 10, and the handrail 12 from the bottom of the slab 10 is carried out. By installing a hose (68, hose) connected to the air inlet 66, the moisture is discharged to the outside. Accordingly, when the air vent 60 or the hose 68 is installed, the protrusions 61 and 67 are formed, making it difficult to construct a joint with the waterproof structure, and the installation bottom of the air vent is always the slab 10. ) It is installed on the upper surface or the upper surface of the pus mortar (not shown) is not a great help to the moisture discharge of the heat insulating material (22, see FIG. 1) portion that actually generates a lot of moisture.

In addition, as a waterproof structure, the method of forming a urethane type coating film layer may be used. However, compared with the asphalt sheet method, the method using the urethane has the advantage of having fewer joints and easier construction of connecting parts such as air vents, while in contact with water for a long time, harmful components such as carcinogens are discharged. If the winter temperature is low, the elasticity is low, and has a disadvantage in that it easily ruptures due to vibration and cracking of the structure.

Accordingly, an object of the present invention is to provide a building rooftop greenery landscaping waterproof structure having excellent waterproof effect even when there is a behavior due to vibration and temperature change of the structure.

Another object of the present invention is to provide a building rooftop greenery landscaping waterproof structure having excellent thermal insulation effect.

Still another object of the present invention is to provide a waterproof roof structure of the rooftop greenery landscaping, which is excellent in cold resistance and utilizes an EPDM rubber waterproof sheet.

In order to achieve the above object, the present invention is a first waterproofing material in contact with the surface of the structure; An insulating material formed on the first waterproofing material; And it provides a building rooftop greenery landscaping waterproof structure comprising a second waterproofing material formed on the insulation. In addition, the present invention comprises the steps of forming a first waterproofing material on the surface of the structure; Forming an insulating material on the first waterproofing material; It provides a building rooftop greenery landscaping waterproofing method comprising the step of forming a second waterproofing material on the insulation.
