Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a waterproof structure,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof structure, and more particularly, to a waterproof structure for waterproofing a sidewall of a roof of a roof, a swimming pool, or the like, or a concrete structure requiring waterproofing by utilizing a waterproof sheet.

Waterproofing of concrete structures has been mainly used for coating waterproofing such as urethane waterproofing and elastic film waterproofing. Although the waterproofing method of the coating film is intended to maintain the waterproof performance by securing the resistance against cracking, in practice, the waterproofing layer of the coating film breaks or breaks frequently due to the behavior of the concrete structure. In addition, since the waterproofing method of the coating film is difficult to ensure air permeability, moisture generated in concrete, mortar or the like is not evaporated and remains in the lower part of the coating waterproofing layer. When the concrete or the mortar is corroded by the residual water, the upper part of the corroded concrete or the mortar and the coating waterproof layer are peeled together.

In order to solve the above problems, a waterproofing method using a waterproof sheet has been variously disclosed in, for example, Korean Patent Laid-Open Publication No. 2005-0015091. However, the conventional waterproof sheet waterproofing method is useful for waterproofing the bottom of a concrete structure, but it is very vulnerable to waterproofing of the side wall. In order to compensate for the above drawback, a zinc sheet may be inserted as in Korean Patent No. 10-0732473, or a side wall sheet made of synthetic resin may be applied as in Korean Patent No. 10-1128760. However, the zinc sheet or the synthetic resin does not contribute much to the adhesion to the side wall, though it may be helpful for the waterproofing itself. Accordingly, there is a need for a waterproof structure capable of sufficiently securing the adhesion to the side wall and maintaining the waterproof function of the waterproof sheet.

However, the waterproofing work of the side wall in the actual site is performed by fixing the waterproof sheet or the like to the side wall using an anchor or the like, and then the edge of the waterproof sheet is finished with silicone resin. On the other hand, waterproofing of the side wall requires a guarantee period of at least 10 years. However, if it is finished with a silicone resin, it can not satisfy the guarantee period of 10 years or more due to deterioration of the silicone and deformation of the waterproof sheet. Accordingly, the method of finishing with silicone resin is not suitable for waterproofing the side wall. In particular, a silicone resin finishing method in a water tank such as a swimming pool can not be employed.

A problem to be solved by the present invention is to provide a side wall waterproof structure using a waterproof sheet replacing a method of sufficiently securing the adhesive force with the side wall while maintaining the waterproof function of the waterproof sheet as it is, have.

The side wall waterproofing structure utilizing the waterproof sheet for the purpose of solving the problems of the present invention comprises a side wall of a concrete structure composed of a floor and side walls and composed of an inner laminate and a cover laminate, Wherein the cover layered body is formed by sequentially laminating a second nonwoven fabric, a waterproof layer and a second coat layer on the inner laminated body, wherein the first non-woven fabric layer, the first non-woven fabric layer and the front waterproof sheet are sequentially laminated Wherein the inner laminate is penetrated by the anchors to be fixed to the side wall, the front waterproof sheet extends from the bottom to the side wall, one side of the cover laminate is in contact with the front waterproof sheet of the bottom, And is adhered to the side wall while covering the upper portion of the inner laminate.

The structure of the present invention may further include a reinforcing plate between the front waterproof sheet and the second nonwoven fabric to which the anchor is inserted. The reinforcing plate may be formed of a metal plate or a plastic plate. The side wall waterproof sheet and the third nonwoven fabric are inserted between the waterproof layer and the front waterproof sheet and the second nonwoven fabric is a fourth nonwoven fabric covering the upper side of the inner laminate, have. The waterproof layer and the front waterproof sheet may further include a side wall waterproof sheet and a third nonwoven fabric interposed between the waterproof layer and the front waterproof sheet and a reinforcing plate between the third nonwoven fabric and the second nonwoven fabric to which the anchor is inserted. And a reinforcing plate into which the side wall waterproof sheet and the third nonwoven fabric are inserted between the waterproof layer and the front waterproof sheet and the anchor is inserted between the front waterproof sheet and the side wall waterproof sheet, And can be fused to heat.

In a preferred structure of the present invention, a vent pipe may be disposed between the side wall and the front waterproof sheet, one side of which is positioned between the bottom and the front waterproof sheet, and the other side of which is protruded outside the cover laminate. The vent pipe head of the vent pipe is curved in a U-shape. The vent tube head is fixed to the side wall by a fixing band.

In the structure of the present invention, the second coat layer may be formed of any one of a hydrophilic coat material and a hydrophobic coat material, or the hydrophilic coat material and the hydrophobic coat material may be laminated. At least one of the primer layer and the first coat layer may extend between the cover laminate and the side wall.

The embodiment of the present invention suggests a side wall waterproof structure replacing the method of finishing the waterproof sheet with the silicone resin while maintaining the waterproof function of the waterproof sheet while securing sufficient adhesion with the side wall by utilizing the characteristics of the nonwoven fabric and the coating material . To this end, the side wall waterproofing structure utilizing the nonwoven fabric and the coating material will be described in detail, and the characteristics of the waterproofing structure, particularly the adhesion with the side wall, will be described in detail. The sidewall waterproofing structure of the present invention is applied to a water tank of a roof, a swimming pool, and the like, and waterproofing the side wall of a concrete structure requiring waterproofing.

1 is a cross-sectional view illustrating a first waterproofing structure 100 according to an embodiment of the present invention. It should be understood, however, that the drawings are not intended to be construed in a strict sense, and for the purposes of explanation, there may be elements not shown in the cross section.

1, the first waterproofing structure 100 of the present invention is attached to a side wall 12 of a concrete structure 10 having a bottom 11 and a side wall 12 around a corner 13. The concrete structure 10 can be applied to various structures within the scope of the present invention, such as rooftops, swimming pools and other water tanks, and other structures requiring waterproofing. The bottom 11 is covered with a front waterproof sheet 20 which is bent and extended to the side wall 12. The front waterproof sheet 20 may be made of a variety of known materials, among which a polyvinyl chloride (PVC) waterproof sheet is preferred. The front waterproof sheet 20 may be used alone, or the first nonwoven fabric 21 may be attached thereto. A composite waterproofing method in which a coated film is formed on the front waterproof sheet 20 may be applied.

In the case of the bottom 11, the front waterproof sheets 20 can be overlapped with each other or can be connected with an adhesive or the like without being overlapped with each other. Further, after overlapping and fusion bonding, for example, the front waterproof sheet 20 may be fixed with an anchor or the like by using the reinforcing plate 50 of Fig. The portion of the front waterproof sheet 20 that is in contact with the water supply trough may be formed as a cylinder in the form of a cylinder of the front waterproof sheet 20 and then arranged to have a certain space with the trough so as to facilitate the discharge of moisture. Since these methods are well known, a detailed description thereof will be omitted. If necessary, a separate fabric is inserted between the front waterproof sheet 20 and the bottom 11 in the form of a sheet to be utilized for buffering and humidity control. Further, a pipe made of PVC or the like is installed on the floor 11 through the waterproof sheet 20 to control the humidity.

The first waterproofing structure 100 is disposed on the side wall 12 and comprises a first inner laminate IL1 and a first cover laminate CL1. The first inner laminate IL1 is directly attached to the side wall 12 and the first cover laminate CL1 covers the first inner laminate IL1. One side of the first cover laminate CL1 is in contact with the front waterproof sheet 20 of the bottom 11 and the other side is covered while covering the top of the first inside laminate IL1. The other end of the first cover laminate CL1 is attached to the side wall 12. In some cases, the one side may be folded and horizontally extended on the front side waterproof sheet 20 to be adhered to the front side waterproof sheet 20.

The first inner laminate IL1 is formed by sequentially laminating a primer layer 14, a first coat layer 15, a first nonwoven fabric 21 and a front waterproof sheet 20 in this order. At this time, the front waterproof sheet 20 and the first nonwoven fabric 21 extend from the bottom 11 to the side wall 12. For this purpose, the front waterproof sheet 20 and the first nonwoven fabric 21 are joined to the corners 13, . Since the waterproof sheet is located on the bottom 11 and the side wall 12, this is referred to as a front waterproof sheet 20. When the front waterproof sheet 20 and the first nonwoven fabric 21 are bent from the bottom 11, leakage at the corners 13 can be prevented. The primer layer 14 and the first coat layer 15 are located between the first nonwoven fabric 21 and the side wall 12 and extend to the bottom 11.

The primer layer 14 is for coating the first coat layer 15 on the sidewall 12, and a known composition is used. For example, it may be a resin in which vinyl acetate (EVA), acrylic emulsion, vinyl acetate, polyvinyl acetate, an acrylic emulsion containing a pigment, etc. are appropriately mixed with 100 wt% of water. At this time, the primer layer 14 may be formed by laminating layers having different viscosities by varying the content of each composition and varying the viscosity. In addition to the above composition, at least one selected from butyl acrylate, phthalic acid ester emulsion, epoxy emulsion, phenol emulsion and polyoxyethylene octiphenyl ether emulsion may be added.

The first coat layer 15 has a weak direct adhesion with the front waterproof sheet 20. In other words, if the first coat layer 15 is directly adhered to the front waterproof sheet 20, the adhesive force is weak and falls easily. This is because the hydrophilic component of the first coat layer 15 is not adhered to the hydrophobic front waterproof sheet 20 properly. To prevent this, the first coat layer 15 is adhered to the front waterproof sheet 20 via the first nonwoven fabric 21. Accordingly, the first nonwoven fabric 21 of the present invention is an essential component. The first coat layer 15 includes, but is not limited to, EVA, acrylic resin, vinyl acetate, polyvinyl acetate, and the like. The first coat layer 15 may include a butyl acrylate resin, a phthalate ester emulsion, an epoxy emulsion or a phenol emulsion, Octiphenyl ether emulsion and the like may be added. More preferably, the acrylic first coat layer 15, which is hydrophilic, is often used.

At least one of the primer layer 14 or the first coat layer 15 may extend between the first cover laminate CL1 and the side wall 12. For example, if the primer layer 14 extends between the first cover laminate CL1 and the side wall 12, or the primer layer 14 and the first coat layer 15 are laminated on the first cover laminate CL1, And the sidewalls (12). When at least one of the primer layer 14 or the first coat layer 15 extends between the first cover laminate CL1 and the side wall 12, the binding force between the second nonwoven fabric 40 and the side wall 12 .

One example of the first nonwoven fabric 21 is a mesh structure that facilitates the impregnation or penetration of the liquid first coat layer 15 and serves as a buffer for protecting the front waterproof sheet 20. Another example of the first nonwoven fabric 21 is a felt-like structure formed by arranging the fibers in parallel or in a negative direction without being subjected to a woven fabric process, and bonding them with an adhesive or the like. The first nonwoven fabric 21 is adhered to the front waterproof sheet 20 by thermal bonding or synthetic resin adhesive. The first nonwoven fabric 21 may be made of a synthetic resin such as polyolefin, polyester or the like. The first nonwoven fabric 21 of the present invention may be made of a material having a strong bonding force with the first coat layer 15. The first nonwoven fabric 21 may be coated with a resin having a strong binding force with the first coat layer 15, for example, polyvinyl acetate impregnated.

The first nonwoven fabric 21 is preferably integrally formed of a nonwoven fabric and a waterproof sheet firmly bonded to the front waterproof sheet 20. The first nonwoven fabric 21 may be formed by extending a nonwoven fabric attached to the front waterproof sheet 20 covering the bottom 11. However, if the front waterproof sheet 20 covering the bottom 11 does not have a nonwoven fabric, the first nonwoven fabric 21 positioned on the side wall 12 may be separately attached to the front waterproof sheet 20 .

The anchor 30 is a screw, a nail, or a bolt, and is fixed to the side wall 12 through the first inside laminate IL1. Of course, the front waterproof sheet 20 may be fixed only to the first coat layer 15 via the first nonwoven fabric 21, but the adhesion of the first coat layer 15 and the front waterproof sheet 20 It can be detached by wind, an external force, or the like, so that it can be more reliably engaged through the anchor 30. That is, the front waterproof sheet 20 is primarily adhered to the first coat layer 15, and the first inner laminate IL1 is fixed with the anchor 30 to enhance the sidewall adhesion force. On the other hand, in the prior art, there is a fixing by an anchor, but there is no bonding with the first coat layer 15 via the first nonwoven fabric 21, so that the bonding force as in the embodiment of the present invention can not be obtained. The spacing of the anchors 30 is adjusted in consideration of the size and shape of the side wall 12 to which the first waterproofing structure 100 of the embodiment of the present invention is applied.

The first cover laminate CL1 complements the side wall waterproofing by the first inside laminate IL1 and securely fixes the first inside laminate IL1 to the side wall 12. [ To this end, the first cover laminate CL1 surrounds the first inner laminate IL1, and the upper portion thereof is attached to the side wall 12. Further, since the first cover laminate CL1 covers the anchor 30 of the first inner laminate IL1, corrosion and disassembly of the anchor 30 are prevented. If the first cover laminate CL1 is not provided, the front waterproof sheet 20 is fixed only by the first coat layer 15 when the anchor 30 is corroded or disassembled. Thereby, there is a high possibility that separation of the front waterproof sheet 20 occurs. The first cover laminate CL1 according to the embodiment of the present invention is intended to more secure the bonding of the front waterproof sheet 20 and further to maximize the waterproof effect.

The first cover laminate CL1 is formed by laminating a second nonwoven fabric 40, a waterproof layer 41 and a second coat layer 42. [ The material of the second nonwoven fabric 40 is the same as that of the first nonwoven fabric 21. The waterproof layer 41 is coated with a waterproofing agent containing an adhesive resin, an emulsifier, a defoaming agent, a dispersant, a preservative, a thickener, a pigment, water and the like. The adhesive resin includes, for example, an ethylene-vinyl acetate copolymer (EVA), a silicone resin, a latex, and an acrylic emulsion resin. The waterproofing agent can be selected variously within the scope of the present invention.

The second coat layer 42 may be made of any one of hydrophilic and hydrophobic coat materials. The hydrophilic coating material uses the same material as the first coat layer 15. The hydrophobic coating material may be selected from a material that does not transmit water, such as a material having a polarity such as a hydroxyl group, an amino group, a carboxyl group, or the like and having a functional group having no affinity for water molecules. The second coat layer 42 may be formed by laminating a hydrophobic coat material on the layer including the hydrophilic coat material. In other words, the second coat layer 42 may be formed of a hydrophobic coat material alone or may be formed by applying a hydrophobic coat material on the hydrophilic coat material. A plurality of layers can be laminated on the hydrophilic coat material in units of the hydrophobic coat material. When the hydrophobic coating material is applied, the first waterproofing structure 100 of the present invention can be applied to a water tank such as a swimming pool.

The first waterproofing structure 100 according to the embodiment of the present invention primarily fixes the front surface of the front waterproof sheet 20 with the first coat layer 15 through the first nonwoven fabric 21 and fixes it. Further, the first inner laminate IL1 including the front waterproof sheet 20 is secondarily fixed to the anchor 30. As shown in Fig. Further, the first inside laminate IL1 is wrapped with the first cover laminate CL1 and fixed in a tertiary manner. As described above, the first waterproofing structure 100 is fixed three-dimensionally, thereby enhancing the bonding force of the side wall 12 and maximizing the waterproof effect. The first waterproofing structure 100 according to the embodiment of the present invention is much more excellent in bonding force and waterproofing effect than the conventional method of finishing with a silicone resin.

FIG. 2 is a sectional view for explaining a second waterproofing structure 200 according to an embodiment of the present invention, and FIG. 3 is a plan view showing an example of the reinforcing plate 50 of FIG. At this time, the second waterproof structure 200 is the same as the first waterproof structure 100 except that the reinforcing plate 50 is added. Accordingly, a detailed description of overlapping portions will be omitted.

2 and 3, the second waterproof structure 200 includes a primer layer 14, a first coat layer 15, a first nonwoven fabric 21, a front waterproof sheet 20, and a reinforcing plate 50, And a second inner laminate (IL2) laminated in this order. The reinforcing plate 50 is located between the front waterproof sheet 20 and the first cover laminate CL1. The reinforcing plate 50 preferably covers a part of the front waterproof sheet 20 and includes a reinforcing plate body 51, an anchor insertion hole 52 and a buffer 53. The cushioning portion 53 is a rim of a convex shape and absorbs the impact generated when the anchor 30 is inserted into the anchor insertion hole 52 and fixed to the side wall 12 and the reinforcing plate body 51 is deformed ≪ / RTI > In some cases, the buffer 53 may be omitted.

The reinforcing plate 50 prevents the front waterproof sheet 20 from being damaged by the anchor 30 when the reinforcing plate 50 is fixed by the anchor 30 and the front waterproof sheet 20 is attached to the side wall 12 Ensure strong adhesion. Thus, the reinforcing plate 50 plays a role of fourth-order fixing in addition to the first to third-order fixing described above. The reinforcing plate body 51 is made of a rigid material, and it is preferable that the longitudinal length (height direction) of the side wall 12 is larger than the lateral direction (width direction). The reinforcing plate body 51 is made of a metal plate or a plastic plate, and a steel plate, a stainless steel plate, a color steel plate, a zinc plate, an acrylic plate, or the like can be used. The number of the reinforcing plate 50 and the number of the anchor insertion holes 52 are different depending on the size and shape of the side wall 12. The number of the reinforcing plate 50 and the number of the anchor insertion holes 52 are different from each other. The reinforcing plate 50 is disposed on the front waterproof sheet 20 at regular intervals.

4 is a cross-sectional view illustrating a third waterproofing structure 300 according to an embodiment of the present invention. At this time, the third waterproof structure 300 is the same as the first waterproof structure 100 except that the side wall waterproof sheet 60 and the third nonwoven fabric 61 are added. Accordingly, a detailed description of overlapping portions will be omitted.

4, the third waterproof structure 300 includes a primer layer 14, a first coat layer 15, a first nonwoven fabric 21, a front waterproof sheet 20, a side wall waterproof sheet 60, And a third inner laminate (IL3) in which a nonwoven fabric (61) is sequentially laminated. The side wall waterproof sheet 60 is distinguished from the front waterproof sheet 20 in that the waterproof sheet is limited to the side wall 12. The front and side waterproof sheets 20 and 60 may be bonded with an adhesive, but they are preferably fused with heat. When fused by heat, the front and side wall waterproof sheets 20 and 60 are integrated. The second cover laminate CL2 is the same as the first cover laminate CL1 except that the fourth nonwoven fabric 40a covers the upper portion of the third inside laminate IL3. At this time, the fourth nonwoven fabric 40a may cover a part or all of the third nonwoven fabric 61.

The third nonwoven fabric 61 attached to the side wall waterproof sheet 60 is a medium for bonding the waterproof layer 41 and the side wall waterproof sheet 60 to each other. In other words, if the waterproof layer 41 is directly adhered to the side wall waterproof sheet 60, the adhesive force is weak and falls easily. In order to compensate for this, the waterproof layer 41 adheres to the side wall waterproof sheet 60 via the third nonwoven fabric 61. Although the second nonwoven fabric 40 is shown on the third nonwoven fabric 61, it is also possible that the second nonwoven fabric 40 is not provided on the third nonwoven fabric 61. In this case, the second nonwoven fabric 40 is located only on the upper portion of the third inner laminate IL3. When the front and side waterproof sheets 20, 60 are integrated, the rigidity of the third waterproof structure 300 is increased, and the force against the external force is increased, so that the third waterproof structure 300 is more firmly attached to the side wall 12.

5 is a cross-sectional view illustrating a fourth waterproof structure 400 according to an embodiment of the present invention.

The structure and role of the reinforcing plate 50 are as described in the second inner laminate IL2. Further, the integration of the front and side waterproof sheets 20, 60 and the function and role of the third nonwoven fabric 61 are the same as in the third inner laminate IL3. Accordingly, the advantages of the second and third inner laminates IL2 and IL3 are directly reflected in the fourth inner laminate IL4. At this time, the fourth inside laminate IL4 is covered with the first cover laminate CL1.

6 is a cross-sectional view illustrating a fifth waterproof structure 500 according to an embodiment of the present invention. At this time, the fifth waterproof structure 500 is the same as the fourth waterproof structure 400 except that the position of the reinforcing plate 50 is changed. Accordingly, a detailed description of overlapping portions will be omitted.

6, the fifth waterproof structure 500 includes a primer layer 14, a first coat layer 15, a first nonwoven fabric 21, a front waterproof sheet 20, a reinforcing plate 50, (60) and a third nonwoven fabric (61) are sequentially laminated. The structure and role of the reinforcing plate 50 are as described in the second inner laminate IL2. Further, the integration of the front and side waterproof sheets 20, 60 and the function and role of the third nonwoven fabric 61 are the same as in the third inner laminate IL3. The reinforcing plate 50 is placed on the front and side wall waterproof sheets 20 and 60 so that the fixing of the front waterproof sheet 20 can be more surely secured. At this time, the front and side wall waterproof sheets 20 and 60 are fused with heat. The fifth inner layered body IL5 reflects the merits of the second and third inner layered bodies IL2 and IL3 as they are. At this time, the fourth inner laminate IL5 is covered with the second cover laminate CL2.

7 is a sectional view for explaining a modification of the waterproofing structures according to the embodiment of the present invention. At this time, the modification example is the same as the first waterproofing structure 100 except that the first waterproofing structure 100 is taken as an example and a vent pipe 70 is added. Accordingly, a detailed description of overlapping portions will be omitted. The vent pipe 70 is also applied to the second to fifth waterproof structures 200, 300, 400, and 500 of the present invention.

7, the vent pipe 70 is in the form of a pipe, one side of which is located between the bottom 11 and the front waterproof sheet 20 and the other side is the side of the first waterproof structure 100 on the side wall 12 . The vent pipe 70 may be formed of a pipe, a plastic, a metal, or the like having a flow path therein. The vent tube 70 in the first waterproof structure 100 may pass between the side wall 12 and the primer layer 14 or between the primer layer 14 and the first coat layer 15. The vent pipe head 71 protruding outside the first water repellent structure 100 is bent in a U-shape so that rainwater and the like are prevented from penetrating. Preferably, the vent tube head 71 is fixed to the side wall 12 with a fixing means such as a fixing band 72. The direction of the end of the vent pipe head 71 may be different depending on the environment to which the waterproof structure of the present invention is applied.
