More particularly, the present invention relates to a technique relating to waterproofing and anticorrosive properties of buildings, and more particularly, to a technology relating to waterproofing and anticorrosion of buildings, The present invention relates to a waterproof / antistatic structure combined with a sheet and an adhesive butyl rubber sheet having an aluminum film on the sheet.

Recently, as a part of the urban environment improvement project, projects for greening the rooftop or creating the indoor garden are increasing rapidly, and it is expected that the demand will be continuously increased in the future. This is recommended because it has various advantages in terms of environmental aspects and economical aspects such as restoration of soil ecosystem, energy saving of air-conditioning and heating, relaxation of urban heat-transfer phenomenon, air purification, noise reduction, improvement of cityscape, It is mandatory to have a rooftop greening facility.

However, rooftop greening causes problems such as leakage of water due to cracking and cracking of concrete structure due to growth of plant roots, acceleration of deterioration of waterproof layer due to constant wetting condition of soil layer. In addition to the fact that the growth potential of the plant roots is very strong, the waterproof layer is drilled and the problem of the structure occurs. In addition, the root of the plant itself may penetrate into the concrete surface.

Therefore, in order to stabilize the rooftop greening, a rooftop greening part should be constructed in a manner that does not affect the structural stability and durability by constructing a safe base for the structure to which the rooftop greening part is applied. It is necessary to form an antifouling layer to protect the waterproof layer.

For this reason, a variety of modern books have been made. For example, there is an example in which a woven fabric or non-woven fabric, which has been chemically treated in the vicinity of a room, is laid and a plant growing layer is provided thereon. However, there is a problem that the chemical lyze near the room may inhibit the growth of the plant roots, reduce the effect of the aging, and increase the cost cost.

Accordingly, the inventor of the present invention has developed a waterproofing / antifogging structure that prevents the root of a plant from leaking between a sheet and a base surface by using a triple-layered aluminum layer on the waterproof sheet and the antiperspirant sheet.

The present invention has been developed to improve the disadvantages of the conventional waterproofing / antifouling sheet. The present invention provides a waterproof sheet having a thickness of at least a certain level and having a heat insulating effect, and a tape-shaped butyl rubber having a release paper Is provided.

In addition, aluminum film is adhered to the anticorrosion sheet to prevent plant root penetration in advance, but it is formed of a triple aluminum layer even when the root penetrates, thus providing a composite waterproofing / antiperspirant structure that can prevent penetration of plant roots There is a technical problem.

In order to solve the above-mentioned technical problems, A primer layer (10) to which a primer is applied on the substrate (A); The lower surface layer 20a is made of a heat reflecting film made of aluminum and the intermediate layer 20b is made of a waterproof layer and the upper surface layer 20c is made of a nonwoven fabric 26, A first sheet layer 20 integrated; The joint portion reinforcement 30a is attached to the joint portion between the first sheet layer 20 and the adjacent first sheet layer 20 to fix the adjoining first sheet layers 20 to each other, A joint reinforcing layer 30 to which the reinforcing layer 30b is applied; A coating film waterproofing layer 40 on the entire surface of the joint reinforcing layer 30 to apply the coating film for floor use to the floor; A second sheet layer 50 onto which a butyl rubber sheet 50a with an aluminum film F adhered is adhered on the film waterproof layer 40; And a finish layer 60 on which a waterproof layer protection material 62 is applied on the second sheet layer 50 and an unfired concrete 64 is laid on the waterproof layer protective material 62. The nonwoven fabric The nonwoven fabric 26 of the first sheet layer 20 and the aluminum film F are formed in the same direction from the intermediate layer 20b in the same direction, A wing adhesive layer 22a and a first sheet layer release sheet 22b are provided under the wing portion 22 of the aluminum film F while the second sheet layer The butyl rubber sheet 50a of the present invention is formed in the form of a tape having a second sheet layer release sheet 50b at a lower portion thereof and is continuously arranged in one direction and overlapped with each other locally. It provides a composite waterproofing and anti-glare structure using an aluminum layer.

According to the present invention, the following effects can be expected.

First, since the waterproof sheet and the antifogging sheet are laminated to form a triple aluminum layer, the present invention has an effect of efficient movement.

Second, since the present invention uses a carpet sheet made of an eco-friendly tape comprising butyl rubber and a releasing paper, a separate curing period is not necessary and shortening of air shortens the life of the conventional waterproofing and antifouling sheet due to the diluent There is an eco-friendly effect without generating carbon dioxide.

Third, the present invention can provide a waterproof / antiperspirant sheet exhibiting a heat insulating effect of a certain level or more merely by forming a thin heat reflecting film without using a thick heat insulating material.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view showing a laminated state of a composite waterproofing / antifriction structure using an adhesive butyl rubber sheet and a triple aluminum layer according to the present invention. FIG. As shown in Fig. 1, the present invention comprises a substrate (A); A primer layer (10) to which a primer is applied on the substrate (A); The lower surface layer 20a is made of a heat reflecting film made of aluminum and the intermediate layer 20b is made of a waterproof layer and the upper surface layer 20c is made of a nonwoven fabric 26, A first sheet layer 20 integrated; The joint portion reinforcement 30a is attached to the joint portion between the first sheet layer 20 and the adjacent first sheet layer 20 to fix the adjoining first sheet layers 20 to each other, A joint reinforcing layer 30 to which the reinforcing layer 30b is applied; A coating film waterproofing layer 40 on the entire surface of the joint reinforcing layer 30 to apply the coating film for floor use to the floor; A second sheet layer 50 onto which a butyl rubber sheet 50a with an aluminum film F adhered is adhered on the film waterproof layer 40; And a finish layer 60 on which a waterproof layer protection material 62 is applied on the second sheet layer 50 and an unfired concrete 64 is laid on the waterproof layer protective material 62. The nonwoven fabric The nonwoven fabric 26 of the first sheet layer 20 and the aluminum film F are formed in the same direction from the intermediate layer 20b in the same direction, A wing adhesive layer 22a and a first sheet layer release sheet 22b are provided under the wing portion 22 of the aluminum film F while the second sheet layer The butyl rubber sheet 50a of the second sheet layer 50 is formed in the form of a tape having a second sheet layer release sheet 50b at the lower part thereof and is continuously arranged and overlapped locally toward one direction.

Figure 2 shows an embodiment of a first sheet layer 20 according to the present invention.

The present invention relates to a waterproof sheet comprising a waterproof layer made of a waterproof material, wherein the lower surface layer 20a is made of a heat reflecting film made of aluminum and the upper surface layer 20c is made of a nonwoven fabric 26 There are technical features to construct. That is, a conventional waterproof sheet may be composed of a laminate structure of a waterproof layer or a variety of materials including a waterproof layer (including a heat insulating material such as styrofoam). The present invention can be applied to a waterproof sheet, And the upper surface layer 20c is constituted by a nonwoven fabric 26 in which an aluminum film F is thermally fused and integrated.

In the first sheet layer 20 according to the present invention, the intermediate layer 20b may be formed of an asphalt type, a synthetic rubber type, a synthetic resin type (PP, PE, etc.) It is expected that the waterproof performance and the heat insulation performance can be expected.

In the first sheet layer 20 according to the present invention, the aluminum heat reflecting film 24 of the lower surface layer 20a serves as a kind of heat insulating layer which protects the waterproof layer and blocks heat transfer. In particular, the aluminum thermal radiation film 24 of the lower surface layer 20a reflects the heat emitted from the substrate surface A when the first sheet layer 20 is placed on the substrate surface A, Thereby contributing to reduction of heat loss. The aluminum heat radiation film 24 of the lower surface layer 20a can be formed by pressing aluminum foil or vapor-depositing aluminum in the process of manufacturing the waterproof sheet.

In addition, the upper surface layer 20c of the first sheet layer 20 according to the present invention is composed of a nonwoven fabric 26. An aluminum film (F) is thermally fused to the inside of the nonwoven fabric (26). As described above, the first sheet layer 20 itself is excellent in the effect of preventing the intrusion of plant roots because the aluminum layer is double. The nonwoven fabric 26 can be simply attached in the process of manufacturing the waterproof sheet. As shown in FIG. 2, the nonwoven fabric 26 is provided with extended wings which protrude more than other structures, so that the nonwoven fabrics 26 overlap when the first sheet layers 20 are joined together. Since the wing portion 22 is provided on the aluminum film F positioned below the nonwoven fabric 26 as well as the nonwoven fabric 26, the wing portion 22 of the nonwoven fabric 26 is formed on the wing portion 22 of the aluminum film F ) To maintain weight and shape. Accordingly, it is possible to suppress the deformation of the wing portion 22 and smoothly fold the chip. 2, the present invention further includes a wing adhesive layer 22a and a first sheet layer release sheet 22b. The wing adhesive layer 22a is formed on the exposed surface of the aluminum film (F) wing portion 22 of the upper surface layer 20c and the first sheet layer release sheet 22b is provided to protect the wing adhesive layer 22a. As described above, the blade adhesion layer 22a and the first sheet layer release liner 22b allow the lap joint between the first sheet layer 20 to be treated more quickly.

In the embodiment of FIG. 2, the lower surface layer 20a of the first sheet layer 20 is processed by embossing. The embossing serves as a shock absorbing cushion, and the intermediate layer 20b is formed on the surface A, So as to form an air discharge passage. The shape and structure of embossing can be any shape, such as hemispherical, cylindrical, crossed, or polygonal.

Figure 3 shows an embodiment of a second sheet layer 50 according to the present invention.

The second sheet layer 50 according to the present invention has a technical feature that the aluminum film F is attached on the upper portion and the butyl rubber sheet 50a is formed on the lower portion. The butyl rubber sheet 50a is formed by extruding a butyl rubber raw material into a sheet form using a molding machine or the like. The butyl rubber sheet 50a is provided with a pressure-sensitive adhesive layer coated with a pressure-sensitive adhesive on the inner surface thereof. The release paper is attached to the inner surface of the butyl rubber sheet 50a. That is, the butyl rubber sheet 50a is in the form of a tape, and does not require a separate curing period when the second sheet layer 50 is applied. In addition, if it is used in the form of tape, it is environment-friendly because there is no generation of carbon dioxide due to the diluent which is caused when the joint of the waterproof sheet is applied in the conventional method, and the release paper is attached as a product without mixing the materials like other waterproof. It is shortened and construction is possible regardless of the season.

As shown in FIG. 3 (b), the plurality of second sheet layers 50 are locally superimposed and continuously arranged in one direction. In the present invention, the overlapping portion is usually about 100 mm, but the width of the overlapping portion may be variously adjusted by the user. Even when the second sheet layer 50 is formed by locally overlapping the butyl rubber sheet 50a as described above, since the butyl rubber sheet 50a is formed in the form of a tape, Etc.), it is possible to fix the adhesive between the second sheets.

Further, since the butyl rubber sheet 50a is attached to the upper portion of the aluminum film F, the anti-vibration function can be added to the butyl rubber sheet 50a, thereby improving the overall performance. More specifically, an aluminum film deposited on the first sheet layer and an aluminum film adhered to the butyl rubber sheet in the second aluminum layer and the second sheet layer are laminated to form a triple aluminum layer structure. As described above, the triple aluminum layer structure prevents the roots of the plant from leaching into the waterproof layer, thereby maximizing the waterproofing and antifoaming effect.

The construction method of the present invention will be described with reference to FIG.

First, the upper concrete slab layer, which is the uppermost layer of the structure, is cleaned by using a comb or a cleaner. In this case, when installing on the existing waterproof layer, repair only the damaged part of the existing waterproof layer to secure smoothness and clean the foreign material while keeping the waterproof layer firmly formed.

Then, the primer is applied to the joint portion of the sheet to be adhered over the entire slab layer or afterwards. After the primer is applied, a joint coating waterproofing material 30b (urethane or the like) may be additionally applied to the joint portion of the waterproof sheet before the waterproof sheet is placed on the waterproof sheet, though not shown in the drawings.

Thereafter, the first sheet layer 20 having the aluminum heat radiation film 24, the waterproofing layer and the nonwoven fabric 26, which is excellent in insulation property, is formed on the primer layer 10. The first sheet layer 20 may be wound in a roll state before the operation. In this case, the first sheet layer 20 is horizontally closely contacted with the bottom surface to be watertight so that a clearance is not formed. At this time, the first sheet layer release sheet 22b of the wing portion 22 is removed and the wing adhesive layer 22a is overlapped with the adjacent first sheet layer 20.

Then, the joint portion reinforcement 30a is attached to the joint portion and the corner joint portion of the first sheet layer 20 to fix the adjoining first sheet layers 20 to each other, and the joint coat waterproofing material 30b is applied thereon. In this case, it is preferable that the joint stiffener 30a, which is laminated on the upper surface of the joint portion of the first sheet layer 20, uses a fiberglass as a grid-like net. The joint coating waterproofing material 30b may be epoxy, urethane, polyurea, silicon, or the like. In a preferred case, the urethane used as the joint coating waterproofing material 30b penetrates and hardens at the joining portions of the fiberglass as the joint reinforcement 30a and the first sheet layer 20, thereby bonding the first sheet layers 20 to each other It is sure to fix and protect.

Thereafter, the bottom coating film waterproofing material is applied over the entire upper surface of the first sheet layer 20, and then cured until it is possible to walk.

Then, when the bottom coating film waterproofing material is cured, a second sheet layer 50 made of a butyl rubber sheet 50a in the form of a tape on which aluminum is adhered is applied. In this case, the second sheet layer release sheet 50b attached to the lower part of the butyl rubber sheet 50a is removed without a separate curing time, and the tape is bonded onto the reinforced first sheet layer 20.

Finally, a waterproof layer protection material 62 (PE foam or the like) is applied on the second sheet layer 50, and a protective mortar or non-porous concrete 64 is laid on the second sheet layer 50. When the mortar or concrete is cured, fill the soil with the desired height and plant trees and plants.
