Recently, artificial greening of building structures has been actively implemented in terms of urban ecological restoration and differentiation of buildings. Such artificial greening is proposed as a way to solve problems such as environmental pollution, ecosystem destruction and climate change in cities. have. In addition, it provides emotional effects such as physical and mental relaxation through energy saving of heating and cooling of buildings, cultivation of flowers, improvement of aesthetics of rooftops, comfortable exercise and formation of resting space.

Generally, it consists of a waterproof layer-proof layer-drainboard-filter layer-soil layer-plant layer. Among them, the waterproof layer and the waterproof layer are important in consideration of long-term durability and economic maintenance cost.

The waterproofing layer for artificial greenery acts to block the water, and the waterproofing layer is the main required performance to protect the waterproofing layer from the infiltration of plant roots, but it receives mechanical shock and damage by greening and repairing equipment, Damage from sustained long-term loads is caused by the penetration of plant roots with strong growth capacity to penetrate even small gaps. In addition, when water is always in the upper part of the waterproof layer and is placed in a humid environment, it may cause water pollution due to the deterioration of the waterproof layer and the elution of harmful substances from the surface, and even the smallest defects in the joints, joints and joints. This occurs, and planting management such as chemical fertilizer or control is made, and is susceptible to chemical erosion by microorganisms and chemicals. Thus, the waterproof and weatherproof layers must have the same durability as the life of the building.

EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail.

Waterproofing-proof composite 100 for artificial greening of the present invention, as shown in Figure 1, the waterproofing material 10, the coating film waterproofing layer 11 is formed on the substrate 12; A waterproofing material 20 bonded to one surface of the waterproofing material 10; And it is characterized in that it comprises an adhesive substrate 30 bonded to the root material 20.

Waterproofing material 10 applied to the present invention is a coating film waterproofing material composition is impregnated or applied to the coating film waterproofing layer-forming substrate 12 to form a coating film waterproofing layer (11).

It is preferable that the base material 12 exhibits surface absorbency, and a polypropylene long fiber or short fiber nonwoven fabric, a polyester long fiber or short fiber nonwoven fabric, or various woven fabrics having such characteristics can be used. Among them, a polyester nonwoven fabric having a long fiber structure and a hydrophilic and absorbent surface having excellent fibrous structural binding strength is more preferable in that a uniform waterproof layer can be formed when impregnating or applying a coating waterproof composition to form a coating layer.

The coating film waterproofing composition for forming the coating film waterproofing layer 11 can be used alone or in combination of two or more types of one-component or two-component coating materials such as cement-based polymer, acrylic, urethane, epoxy, or glass fiber reinforced plastic (FRP). Can be. Among them, the cement-containing polymer coating waterproofing composition is more preferable in terms of manufacturing process and production efficiency.

The waterproof material 10 is produced by impregnating or applying the coating film waterproofing material composition to the substrate 12 and then forming a coating film waterproofing layer 11 of uniform quality through a high temperature drying process.

The waterproofing material 20 applied to the present invention is bonded to one surface of the waterproofing material 10, and is used as a single or two or more kinds of mixed resins selected from polyethylene-based, ethylene vinyl acetate-based, and polyethylene terephthalate-based resins as a central substrate of the composite material. It may be made of a film or sheet. Among these, blending of hard polyethylene and soft ethylene vinyl acetate shows the intermediate characteristics of soft and hard, and at the same time, it is possible to secure waterproofing and waterproofing function, and is also easy in the field application.

The adhesive base 30 is adhered on the root barrier material 20 and is for fixing the waterproof-cabin composite, preferably exhibiting surface adsorption, and having a polypropylene long fiber or short fiber nonwoven fabric and polyester sheet having such characteristics. Fiber or short fiber nonwoven fabric, various woven fabrics, etc. can be used. Among them, a polyester nonwoven fabric having a long fiber structure is preferable in that the impregnation of the fixing adhesive is easy to provide a rigid mechanical fixing structure.

In addition, as an adhesive used for fixing the waterproof-proof composite, an appropriate product corresponding to the KS F 3211 standard, which basically has waterproof performance commonly used in the art, may be used.

The manufacturing method of the waterproof-proof composite 100 of the present invention configured as described above is, for example, impregnated or coated with a coating film waterproofing composition on the substrate 12 by using a conventional method in the art, and then dried at a high temperature. By forming the coating film waterproof layer 11 to produce a waterproof material (10). The root barrier material 20 is produced by filming or sheeting synthetic polymers in a molten liquid state using a conventional method in the art. Subsequently, the waterproofing material 10 and the waterproofing material 100 may be manufactured by simultaneously bonding and cooling the waterproofing material 10 and the adhesive base material 30 to the upper and lower portions of the manufactured waterproofing material 20.

In particular, the waterproof-proof composite 100 of the present invention is integrated by the waterproofing material 10, the waterproofing material 20 and the adhesive base 30 by bonding, to the physical properties such as surface hardness, tensile strength and simulated settlement It will have a specific range of values, and by satisfying these properties at the same time, sufficient resistance to plant root penetration can be exhibited without damage, and long-term rooting performance can be maintained.

Specifically, the surface hardness (shore A, JIS K 6301 A) is preferably 80 or more, and more preferably 80 to 90. If the value is less than 80, soft properties are exhibited, and it is difficult to secure the weather resistance.

In addition, the tensile strengths KS F 4911 and F 4917 are preferably 50 N / mm or more, and more preferably 50 to 95 N / mm. If the value is less than 50N / mm, the molecular structural cohesion, i.e., the denseness and cohesiveness of the waterproof-rooted composite is insufficient, and the resistance to root penetration of the plant is lowered. If the value exceeds 95N / mm, the flexibility is insufficient. It may be difficult to manufacture in the form of a roll-shaped sheet.

In addition, the simulated sinking load (using the test apparatus for evaluating the waterproofing resistance of the roof layer, Korean Journal of Architecture Research, Vol. 28) simulates plant root shape and penetration and plays the biggest role in determining the rooting performance. It is preferable that it is 50N or more, More preferably, it is 50-60N. If the value is less than 50N, the molecular structural cohesion, that is, the lack of compactness and cohesion of the waterproofing-rooted composite, may lower the resistance to plant root penetration.

The surface hardness, tensile strength, and simulated settlement characteristics as described above have a constant correlation with each other, and thus, the resistance to infiltration of plant roots can be determined through each of the above properties or a combination of two types of properties. It is impossible to do. Therefore, in the present invention, satisfying the surface strength, the tensile strength and the simulated settlement characteristics at the same time is most preferable for improving the penetration resistance to the plant roots to impart waterproofing and rooting performance.

In the waterproof-proof composite 100 of the present invention, the thickness of the waterproof material 10 is 0.56 to 0.71mm, the thickness of the waterproof material 20 is 1.00 to 1.20mm, the thickness of the adhesive substrate 30 is 0.45 to It is preferable that it is 0.63 mm. If the thickness of the waterproof layer is less than 0.56 mm, there may be a problem in waterproof performance due to lack of resistance to external damage and impact, and if the thickness exceeds 0.71 mm, the thickness becomes excessively thick, which lowers the flexibility of the waterproof layer itself. The addition of phases reduces the efficiency of production. If the thickness of the barrier layer is less than 1.00 mm, the tensile strength and the simulated settlement characteristics of the present invention are degraded, so that it is difficult to satisfy the tensile strength and the simulated settlement characteristics of the waterproof-proof composite of the present invention, which may be damaged by the root penetration of the plant. In the case of exceeding 1.20 mm, the thickness becomes excessively thick, which lowers the flexibility and makes handling difficult. In addition, when the thickness of the adhesive base material is less than 0.45 mm, the fixing work of the waterproofing layer is insufficient, and when the thickness of the adhesive base material is more than 0.63 mm, the penetration layer is insufficient due to the excessive thickness and the impregnating base material is not sufficiently impregnated. There is a risk of falling out.

In order to simultaneously satisfy the surface strength, the tensile strength and the simulated settlement characteristics and to be able to fully exhibit the function of waterproofing-proofing, it is preferable that each layer is constituted within the above thickness range.

In addition, the total thickness of the waterproof-proof composite is preferably 2.01 to 2.54 mm. If the total thickness is less than 2.01 mm, there is a problem that is vulnerable to physical impact damage during construction, and if the total thickness exceeds 2.54 mm, the rooting performance may be improved, but it is inefficient due to the increase of manufacturing cost and the difficulty of work. .

As described above, the waterproof-proof composite 100 of the present invention is a simple manufacturing method, the waterproofing material 10, the waterproofing material 20 and the adhesive base 30 is already formed, the coating film waterproof layer 11 is formed integrally. As it is applied at the same time, it is not necessary to construct or laminate the waterproof layer and the waterproof layer separately in the field construction, thereby improving the process efficiency and satisfying the surface strength, tensile strength and simulated settlement characteristics at the same time. Can exert.

In addition, the present invention provides a construction method of the waterproof-proof composite, the method comprising the first step of adjusting and arranging the construction base surface; A second step of bonding the waterproof-proof composite to the arranged base surface, wherein the waterproofing materials of adjacent composite materials overlap each other; A third step of processing the overlapping portions of the joined composite; A fourth step of processing an edge of the composite material having the overlapped portion processed therein; And a fifth step of processing the raised and end portions of the edge-treated composite material. Hereinafter, the construction method will be described with reference to FIGS. 2 to 4.

First, the first step is adjusting and arranging the construction base surface for constructing the waterproof-proof composite, where the deterioration part is removed and the damaged part is repaired.

The second step is the step of bonding after installing the waterproof-proof composite on the clean surface. Specifically, the primer layer 32 and the adhesive 31 are installed in a predetermined width at a portion set for fixing the waterproof-proof composite 100, and then the composite 100 is installed and pressed to fix it. At this time, it is preferable to join after allowing the neighboring composite material to overlap when the composite material is installed. In addition, the machine fixing 41 is processed using a knife block-fastening screw or the like for a more firm fixing of the overlapping roots.

The third step is to treat the overlapped portion of the bonded composite material. The indirect hot air is applied to the mechanically treated composite material to maintain continuity through the complete fusion operation. Next, the glass fiber mesh 42 and the sealing material 43 are reinforced to secure the continuity of the waterproof layer.

The fourth step is the edge treatment step, which is the part where the construction base surface of the composite material and the two wall surfaces meet.

In general, the edge part is cut and a part of the sheet is processed by overlapping, and according to this method, it is difficult to construct the vertical part of the joint or overlapping part, and the overlapping part is not watertight and the water moves. To provide a passageway. Since the roots of plants grow along the path of water movement, it is difficult to secure rooting as a result.

Therefore, the edge treatment step is an important step for ensuring the root repellency, in particular, the present invention is characterized by using a chamfering method of folding the corner portion to one wall surface without cutting the composite material. Specifically, the edge portion is bonded using an adhesive and then fixed by the chamfering method. At this time, the machine is fixed to the end of the chamfered portion for sufficient fixing and then firmly fixed by reinforcing treatment with glass fiber mesh and sealing material.

The fifth step is the lifting portion and the end portion treatment step, which is processed to be installed up to a specified height based on the surface layer of the artificial recording system consisting of a drainage plate-filter layer-artificial soil layer (see FIG. 6) applied to the composite material. Step. Specifically, install the raised portion up to the specified height and bond using the installed adhesive, and then bonded and fixed the end of the bonded raised portion by mechanical fixing treatment and then firmly fixed by reinforcing the end portion with glass fiber mesh and sealing material Let's do it.

According to the construction method as described above, it is possible to secure a long-term waterproof and waterproof performance at the same time by using the waterproof-proof composite that can be applied regardless of the type of artificial greening.

Hereinafter, preferred examples are provided to aid the understanding of the present invention, but the following examples are merely for exemplifying the present invention, and it will be apparent to those skilled in the art that various changes and modifications can be made within the scope and spirit of the present invention. It is natural that such variations and modifications fall within the scope of the appended claims.
