Description

[0001] WATERPROOF LINING METHOD AND STRUCTURE [0002]

The present invention relates to a waterproof lining method and structure, and more particularly, to a waterproof lining method and structure capable of improving waterproof characteristics.

Waterproof lining is applied to the surface of various engineering works or building structures such as water tanks, water depots, drainage ponds, water purification plants, fishing ponds, salt tanks, chemical plants, waste treatment plants, gas stations, car washes and tunnels. Particularly, there are water tank, water intake reservoir, water reservoir, water treatment plant, fish farm, salt water tank, etc. for concrete tank or steel tank water tank to drain a large amount of water. Therefore, waterproof lining is installed in the water tank to secure the durability of the water tank, Thereby preventing contamination of the water.

The waterproof lining construction is generally a wet method of applying a resin. However, the wet method is complicated in process, difficult to have uniform waterproofing property, and may cause problems due to harmful substances.

In consideration of this problem, a dry method in which a stainless steel is welded or a polyethylene-based waterproof sheet is attached is recently applied. Korean Patent No. 1418537 discloses an example of a technique using a polyethylene-based waterproof sheet.

However, the use of stainless steel is costly to install and may cause contamination due to the reaction with water in the welded portion of the stainless steel, or the strength of the stainless steel may be reduced. When a polyethylene-based waterproof sheet is used, the waterproof sheet may have a thickness of about 3 mm, so that foreign matter such as a waterproof sheet may be lifted from the overlap joint or water may leak to the overlap joint.

In the dry method, since the work surface must be dried again after cleaning the work surface before lining construction, the construction time is long and the construction cost is increased due to the cost for drying. Further, when the adhesive strength between the work surface and the waterproof sheet is not excellent, the waterproof property may not be excellent.

The present invention seeks to provide a waterproof lining method and structure capable of improving structural stability and waterproofing properties.

A waterproof lining structure according to an embodiment of the present invention includes a groove formed in a work surface; An adhesive filled in the groove; An adhesive plate fixed to the work surface by a fastening member extending to the inside of the groove; And a waterproof layer positioned above the adhesive plate and the work surface.

According to the present embodiment, a groove is formed in the work surface, and the fastening member fastened to the adhesive plate together with the filler material is positioned in the groove, so that the adhesive plate can be stably fixed, Breakage, leakage, and the like can be solved. Thus, the structural stability and the waterproof property of the waterproof lining structure can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, a waterproof lining method and a waterproof lining method according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a flowchart illustrating a waterproof lining method according to an embodiment of the present invention. 2A to 2H are cross-sectional views illustrating a waterproof lining method and structure according to an embodiment of the present invention.

Referring to FIG. 1, the waterproof lining method according to the present embodiment comprises a preprocessing step S10 and a waterproofing step S20.

The pretreatment step 10 may include a chipping step S11, a cleaning step S12, a penetration enhancer application step S13, an exposing agent application step S14, and a primer application step S15.

As shown in FIG. 2A, in the chipping step S11, the cleaning step S12, the penetration enhancer application step S13, and the exponential agent application step S14 of the preprocessing step S10, Perform cleanup operations to remove. Since the work surface 110 on which the waterproof lining method is to be installed is often required to be repaired, when there is contamination or corrosion on the work surface 110 itself, it is necessary to remove the contaminants and remove the rust Because.

Here, the work surface 110 may be any surface that requires waterproofing or a method in various civil engineering or building structures such as a water tank, a water intake, a drainage, a water purification plant, a salt water, a chemical plant, a waste treatment plant, a gas station,

More specifically, the preprocessing step S10 may include a chipping step S11 and a cleaning step S12. In the chipping step S11, the work surface 110 is ground using a grinder. The cleaning step S12 may be performed after the chipping step S11 and the work surface 110 may be cleaned using a high pressure washer. The chipping step S11 and the cleaning step S12 may be omitted depending on the state of the work surface 110.

After the cleaning step S12, the penetration enhancing agent application step S13 may be further performed. In the penetration enhancing agent application step S13, the penetration enhancing agent layer 111 may be formed on the work surface by applying a concrete penetration enhancer. The concrete penetration enhancer penetrates into deteriorated concrete and binds with untreated calcium hydroxide to form ultralight calcium silicate, or it combines with carbon dioxide in air or moisture to form a silicate compound, thereby reinforcing and densifying concrete strength to increase water resistance do. A variety of known materials can be used as reinforcing agents for concrete penetration.

After the penetration enhancer application step (S13), the exponential agent application step (S14) may be further performed. In the exposing agent application step S14, a large crack 110a is formed on the work surface 110 so that the exposing agent 112 is applied to fill the large cracks 110a at the water-collecting sites, . As the exponent 112, various known materials capable of filling the crack 110a can be used.

Next, as shown in FIG. 2B, a primer layer 120 is formed by applying a primer to the work surface 110 in a primer application step (S15). Various materials known as primers for forming the primer layer 120 can be used. For the sake of simplicity, the illustration of the cracks 110a, the penetration enhancer layer 111, the exponent 112, and the like are omitted in Figs. 2B to 2H.

Next, with reference to Figs. 2C to 2H, a description will be given of a water-proof processing step S20 practically water-proofing the work surface 110. Fig. For reference, the primer layer 120 is omitted in FIGS. 2c to 2h for the sake of simplicity.

In this embodiment, the waterproofing step S20 includes a groove forming step S21 for forming the groove 130, a filling step S22 for filling the groove 130 with the adhesive 132, The adhesive waterproof layer 150 and the adhesive plate 140 are positioned and the fastening member 144 is inserted into the groove 130 through the adhesive plate 140 to form the adhesive waterproof layer 150 and the adhesive plate A waterproof layer alignment step S24 for positioning the waterproof layer 160 on the adhesive plate 140 and a waterproof layer alignment step S24 for positioning the waterproof layer 160 on the adhesive plate 140 and the work surface 110 (Step S25). Whereby the waterproof lining structure 100 is formed. And a joint fusing step S26 for fusing the joints of the respective waterproof lining structures 100 after the attachment step S25. This will be explained in more detail.

First, as shown in FIG. 2C, in a groove forming step S21, a groove 130 is formed on a work surface 110 on which a fastening member 144 for fixing an adhesive plate 140 included in a waterproof structure is fixed. do.

Here, the groove 130 is an extended portion (reference numeral 144a in FIG. 2F, the same applies hereinafter) of a fastening member (reference numeral 144 in FIG. 2F, the same applies hereinafter) extending through the adhesive plate 140 and extending into the groove 130, And the adhesive 132 surrounding the adhesive 132 are located inside.

The volume of the groove 130 may be greater than the volume of the fastening member 144 so that the extension 144a of the fastening member 144 may be easily located within the groove 130. [ The depth of the groove 130 is longer than the length of the extending portion 144a of the fastening member 144 and / or the area of the groove 130 is larger than the area of the extending portion 144a of the fastening member 144 It can be wide. In particular, the area of the groove 130 may be wider than the area of the extending portion 144a of the fastening member 144. Then, when the fastening member 144 is positioned inside the groove 130, it can be easily positioned without damaging the inside of the groove 130. The adhesive 132 located inside the groove 130 can be positioned while covering the entire extended portion 144a of the fastening member 144 so that the fastening member 144 is stably fixed in the groove 130 And it is possible to effectively prevent breakage, leakage, and the like caused by the groove 130.

For example, the area of the groove 130: the ratio of the area of the extending portion 144a of the fastening member 144 may be 1: 0.8 to 1: 0.95. If the ratio is less than 1: 0.8, the groove 130 becomes large, and the required amount of adhesive (132 in FIG. 2D, hereinafter the same) is large and the clearance between the groove 130 and the fastening member 144 is large, Can be lowered. If the ratio exceeds 1: 0.95, the area of the groove 130 is not sufficient and the amount of the adhesive 132 is not sufficient, so that it may be difficult to stably fix the fastening member 144. However, the present invention is not limited thereto, and the above-described range may vary.

Then, as shown in FIG. 2D, in the filling step S22, the adhesive agent 132 is filled in the groove 130. Then, as shown in FIG. As the adhesive 132, various materials can be used. For example, a dry epoxy adhesive may be used as the adhesive 132. Alternatively, a wetting waterproofing adhesive composition may be used as the adhesive 132. When a waterproof adhesive composition of a wet type is used as the adhesive 132, it can be applied even in the state of moisture in this embodiment, and the waterproof property can be improved.

For example, the waterproof adhesive composition may comprise a powder mixture comprising a particulate quick-setting powder, an aqueous epoxy subject, and an aqueous epoxy curing agent. Such powder compositions, aqueous epoxy bases, and aqueous epoxy curing agents can be used in situ and blended.

Such a waterproof adhesive composition may be a waterproof mortar composition. Aqueous epoxies are environmentally friendly and can strongly bond with ultrafine fast curing binders to improve the adhesion of waterproofing adhesive compositions, but are expensive. Accordingly, it is an object of the present invention to provide a waterproof adhesive composition capable of improving waterproof adhesive composition's properties such as adhesive strength, waterproof function and seismic function, while reducing the content of aqueous epoxy. This will be explained in more detail.

In this case, the aqueous epoxy base may be contained in an amount of 20 to 35 parts by weight based on 100 parts by weight of the powder mixture, and the aqueous epoxy curing agent may be included in an amount of 3 to 7 parts by weight based on 100 parts by weight of the powder mixture. Here, when the water-based epoxy base material is contained in an amount of less than 20 parts by weight, the powder mixture may be difficult to be stably mixed. If the aqueous epoxy theme is included in excess of 35 parts by weight, the content of the powder mixture may be low and it may be difficult to maximize the effect of the powder mixture. And less than 3 parts by weight of the aqueous epoxy curing agent, the effect of the aqueous epoxy curing agent may not be sufficient. If the aqueous epoxy curing agent is included in an amount of more than 7 parts by weight, the amount of the powder mixture or the aqueous epoxy subject may not be sufficient and it may be difficult to sufficiently exert the effect of the powder mixture or the aqueous epoxy subject.

The powder mixture may comprise a base powder comprising an inorganic binder powder, a filler powder and an ethylene vinyl acetate (EVA) powder.

Here, the inorganic binder powder may comprise a sulfur calcium aluminate _{(3Ca · 3Al 2 O 3 ·} CaSo 4), anhydrous gypsum and at least cement.

Calcium sulphoaluminate can play a role in imparting rapid hardness. If there is water or a large amount of water for a long time in an underground structure or the like, the reaction may be slowed down due to a hydraulic reaction, and the adhesion may be lowered. In the case of attaching a heavy conductor, This problem can be prevented by the fast hardness of the sulfur aluminate. In addition, the water-retaining agent composed of the glycol-based material contained in the aqueous epoxy curing agent of the present invention may prevent the moisture from evaporating and delay the drying of the surface, but may delay the curing and drying, This problem can be avoided by rapid hardening. The anhydrous gypsum is able to exhibit the rapid hardening and swelling properties of calcium sulphoaluminate. When the first type of cement shrinks, the anhydrite gypsum expands, and as a whole, the gypsum is offset so as to be stable. And calcium sulfate aluminate, anhydrous gypsum, and one kind of cement are mixed, so that it can play a role as an adhesive sufficiently. At this time, when the first type cement is mixed with an aqueous epoxy resin or the like, it is cured and the role of the adhesive agent or the adhesive agent can be improved.

As described above, the inorganic binder powder according to this embodiment can maximize the adhesion strength and waterproof performance, including calcium sulfate aluminate, anhydrous gypsum and one kind of cement.

The inorganic binder powder can be used as a solid powder. By increasing the reaction speed and the reaction surface area, the penetration into the matrix and the conductor can be facilitated, thereby improving the adhesive strength of the waterproof adhesive composition and improving the water density and improving the waterproofing ability. Particularly, the binder powder of the high-strength powder can compensate for a decrease in the adhesive strength that can be generated due to the low solids content of the aqueous epoxy.

Accordingly, calcium sulfate aluminate, anhydrous gypsum and first-class cement may be pulverized so as to have a certain specific surface area (or powdery degree) or an average particle size. For example, the calcium sulfurized aluminate or the first cement may have a specific surface area of 6,000 to 12,000 cm2 / g (more specifically, 6,000 to 9,000 cm2 / g) or an average particle size of 2 to 6 um. And anhydrous gypsum can use powder passing through 325 mesh. In this range, the adhesive strength of the waterproof adhesive composition can be improved, water density can be improved, and the effect of improving water resistance can be maximized. However, the present invention is not limited thereto, and the specific surface area, average particle diameter, and the like of the inorganic binder powder may have different values.

The filler powder includes calcium carbonate (CaCO ₃ ) powder, and may further include silica sand powder.

When the calcium carbonate powder is used as the filler powder, the calcium carbonate powder reacts with carbon dioxide to turn into calcium hydrogen carbonate, which provides an opportunity for the untreated calcium hydroxide to react with water for a long term. As a result, the long-term strength of the waterproof adhesive composition can be secured. On the other hand, when the calcium carbonate powder is not used as the filler powder, the inorganic hydroxide powder is subjected to the hydraulic reaction, and the unhydrolyzed calcium hydroxide is converted to calcium carbonate while meeting the carbon dioxide in the air, so that the long-term strength of the waterproof adhesive composition may be deteriorated. The silica sand powder can improve workability of the waterproof adhesive composition and prevent cracking.

The filler powder including calcium carbonate powder, silica powder and the like can be used as a high-molecular powder. By increasing the reaction speed and the reaction surface area, the penetration into the matrix and the conductor can be facilitated, thereby improving the adhesive strength of the waterproof adhesive composition and improving the water density and improving the waterproofing ability. For example, powder of a filler such as calcium carbonate powder or silica sand powder may be passed through a 325 mesh. According to this, the effect according to the above-described high-strength powder can be sufficiently exhibited.

Inorganic binder powders and filler powders have strong physical bonding with aqueous epoxies. When the EVA powder is further included as in the present invention, the EVA powder is chemically bonded to the unreacted calcium ion in the inorganic binder powder. Thus, the strength and adhesion of the waterproof adhesive composition can be increased, and the waterproof property can be improved by forming a three-dimensional matrix structure. As a result, the EVA powder can significantly improve the adhesive strength while greatly reducing the content of the solid content contained in the aqueous epoxy base and curing agent.

The powder mixture may further contain, in addition to the above base powder, a thickener, reinforcing fiber, accelerator, condensation retarder, silica fume and the like.

Here, the thickener may be a cellulose-based material having a viscosity of 3,000 cps to 30,000 cps. For example, methylcellulose, hydroxymethylcellulose or the like having a viscosity of 3,000 cps to 30,000 cps can be used. If the viscosity of the thickener is less than 5,000 cps, the effect of the thickener may not be sufficient. If the viscosity of the thickener exceeds 30,000 cps, the adhesive strength of the waterproof adhesive composition may be lowered, and the viscosity may increase during the post-mixing operation, resulting in deterioration in workability.

The reinforcing fiber can serve to improve the tensile strength at the portion where the waterproof lining is applied. For example, aramid fibers can be used as reinforcing fibers for aerospace, armored vehicles, armor, and fire fighting materials. The aramid fiber can have excellent tensile strength, ductility and flame retardancy, and can also have an earthquake-resistant property. However, the present invention is not limited thereto, and various materials such as polypropylene (PP), polyethylene (PE), and nylon can be used as the reinforcing fiber.

Accelerators can serve to promote condensation. Examples of the accelerator include sodium sulfide (Na ₂ S.9H ₂ O), sodium carbonate (Na ₂ CO ₃ ), lithium carbonate (Li ₂ CO ₃ ), lithium ridroxide (LiOH.H ₂ O), aluminum oxide (Al ₂ O ₃ ).

The coagulation retarder can act as a coagulant together with the accelerator. As the coagulation retarder, one or more of citric acid, tartaric acid, gluconic acid, boric acid, and potassium carbonate may be used.

The silica fume plays a role in improving the waterproof performance.

In this case, it is preferable that 10 to 20 parts by weight of calcium sulfoaluminate, 5 to 15 parts by weight of gypsum powder and 10 to 35 parts by weight of the first kind of cement are added to 100 parts by weight of the whole powder mixture, and 20 to 50 parts by weight of calcium carbonate powder, 0 to 20 parts by weight of silica sand powder, and 1 to 8 parts by weight of EVA powder. And 0.01 to 1 part by weight of reinforcing fiber (aramid fiber), 0.05 to 2 parts by weight of accelerator, 0.01 to 0.8 part by weight of a retardation retarder, 0.07 to 2 parts by weight of Silica fume.

If the calcium sulfate aluminate is less than 10 parts by weight, the quick hardening may not be sufficient. If the calcium sulfoaluminate exceeds 20 parts by weight, the coagulant must be added in excess of the required hardness and the strength may be lowered and the price may increase. When the anhydrous gypsum is less than 5 parts by weight, the expandability is small, and when the anhydrous gypsum is more than 15 parts by weight, the expandability is too large, and the overall stability may be lowered. If the first-kind cement is less than 10 parts by weight, the effect of the first-kind cement may not be sufficient, and if the first-kind cement contains 35 parts by weight, the expandability may be large.

When the amount of the EVA powder is less than 1 part by weight, the effect of the EVA powder may not be sufficient. If the amount of the EVA powder is more than 8 parts by weight, the cost of the material may be increased.

If the weight portion of the thickener is less than 0.005 part by weight, the effect of the thickener may not be sufficient. If the weight portion of the thickener is more than 0.5 part by weight, the adhesive strength of the waterproof adhesive composition may be lowered, and the viscosity may increase during the post-mixing operation, resulting in deterioration of workability. In the present invention, although the inorganic binder powder is composed of a high-molecular weight and the weight portion of the thickener is relatively small, workability can be improved while ensuring a sufficient viscosity suitable for the operation.

If the reinforcing fiber is contained in an amount of less than 0.01 part by weight, the effect of the reinforcing fiber may not be sufficient. If the amount of the reinforcing fibers exceeds 1 part by weight, the content of the other components may be reduced and the properties of the waterproof adhesive composition may be deteriorated.

If the amount of the accelerator is less than 0.05 part by weight, the effect by the accelerator may not be sufficient. If the accelerator is contained in an amount exceeding 2 parts by weight, the coagulation speed becomes excessively large and the adhesion property with the work surface 110 may be lowered.

If the coagulation retardant is contained in an amount of less than 0.01 part by weight, the effect of the coagulation retardant may not be sufficient. If the coagulation retarder is contained in an amount exceeding 0.8 parts by weight, the coagulation speed is slowed, and the construction time may be prolonged or the strength may be lowered.

If the amount of silica fume is less than 0.07 part by weight, the effect of silica fume may not be sufficient. If the silica fume is contained in an amount exceeding 2 parts by weight, the effect of the silica fume may not be greatly improved, only the material cost is increased.

However, the present invention is not limited thereto, and the content of each substance can be modified.

The water-based epoxy base according to the present invention can be formed by forcibly emulsifying and dispersing an epoxy resin in water. That is, the aqueous epoxy subject includes an epoxy resin, water, an emulsifier, and may further include a diluent, an accelerator, and the like. Various known materials such as epoxy resin can be used and water can be used in various kinds of known water such as tap water, water, exponent, ground water, soft water and hard water. Examples of the emulsifier include block copolymers of polyoxyethylene and polyoxypropylene, Copolymers of polyoxyethylene and polyoctyl phenyl ether, sodium dodecylbenzene sulphonate, and the like. As the diluent, an ether-based material may be used. More specifically, butyl glycidyl ether, phenyl glycidyl ether, carboxylyl glycidyl ether, hexanediol diglycidyl ether, butanediol diglycidyl ether, One or more species can be selected.

In this case, the epoxy resin may be contained in an amount of 15 to 20 parts by weight based on 100 parts by weight of the whole aqueous epoxy base, and 0.5 to 1 part by weight of the emulsifying agent may be included. Further, other diluents and accelerators may be further included, May be included. More specifically, the diluent may be contained in an amount of 3 to 5 parts by weight based on 100 parts by weight of the entire aqueous epoxy resin, the accelerator may be included in an amount of 0.5 to 1 part by weight, and the water may be included in an amount of 50 to 80 parts by weight. This range is limited to uniformly mixing the powder mixture while each of the materials exhibits their respective effects sufficiently, and to improve the adhesive strength and waterproof property of the waterproof adhesive composition. However, the present invention is not limited thereto.

The aqueous epoxy curing agent according to the present invention may further comprise a curing agent and a water-retaining agent (or cryoprotectant) composed of a glycol-based material, and may further include an accelerator and a quasi-reaction accelerator.

The curing material includes an amine-based compound, and may include, for example, at least one of polyoxypropylene diamine, triethylenetetramine, and diethylenetriamine.

As the water-retaining agent, a glycol-based substance such as ethylene glycol, propylene glycol and the like can be used. The moisture retaining agent can prevent evaporation of moisture and slow the surface drying. If the moisture-retaining agent is not contained, it is difficult to carry out the continuous operation due to the phenomenon of surface roughness when the water-proof adhesive composition is applied to the mother body and then the conductor to be adhered to the waterproof sheet or the like is adhered. The workability may be deteriorated. This problem may be more serious, especially in outdoor work where there is sunlight or wind. In the present invention, the workability of the waterproof adhesive composition can be improved by including a water-retaining agent that prevents evaporation of water and lowers surface drying.

The reaction control agent participates in the reaction and controls the curing rate, and may include, for example, aniline. The accelerator may be an amine accelerator (for example, an aromatic tertiary amine) as a reaction promoting substance.

The water-retaining agent may be contained in an amount of 1 to 20 parts by weight based on 100 parts by weight of the total amount of the aqueous epoxy curing agent. As an example, 10 to 50 parts by weight of polyoxypropylene diamine, 1 to 20 parts by weight of at least one of triethylenetetramine and diethylenetriamine, 10 to 30 parts by weight of aniline, And 1 to 15 parts by weight of an accelerator. This range is limited to uniformly mixing the powder mixture while each of the materials exhibits their respective effects sufficiently, and to improve the adhesive strength and waterproof property of the waterproof adhesive composition. Particularly, if the water-retaining agent is less than 1 part by weight, the effect of the water-retaining agent may not be sufficient. If the water-retaining agent exceeds 20 parts by weight, the content of other materials may be decreased and other properties may be deteriorated. However, the present invention is not limited thereto.

The waterproof adhesive composition according to the embodiment of the present invention can be well penetrated into small grooves, cracks, or cracks including powder in the form of a high powder. Further, the waterproof adhesive composition can be applied in a sufficient thickness without flowing down from the working surface of the wall or the like, so that cracks, cracks, fine areas and the like can be immediately applied without repairing. The calcium sulfoaruminate and / or the first kind of cement reacts with water, and it can work even if there is moisture due to the principle of eliminating the residual moisture before it remains on the surface due to the heat generation due to the quick reaction. Also, it is possible to prevent the occurrence of water leakage in the groove 130 filled with the waterproof adhesive composition due to its waterproof property.

At this time, in the drawing, a waterproofing adhesive composition is applied so that even when moisture is present in the adhesive 132, a first adhesive layer 134 is applied to the surface of the work surface 110 located outside the groove 130 . The reason why the first adhesive layer 134 is formed in this way is that the surface to be restored is uneven in many cases, so that the adhesive surface of the adhesive plate 140 described later is improved by making the surface even.

As described above, in the present embodiment, since the waterproof adhesive composition having water solubility is used, the first adhesive layer 134 is formed by directly applying the waterproof adhesive composition to the wet and wet working surface 110 without a separate drying step . Therefore, it is possible to reduce the construction time by reducing the time for drying, and the construction cost can be reduced by reducing the cost of using the product for drying.

Of course, if the surface to be restored is uniform, the adhesive plate 140 may be directly attached without forming the first adhesive layer 134. Although the first adhesive layer 134 and the filler 132 are formed together to simplify the process, the first adhesive layer 134 and the filler 132 may be formed in different processes.

2E and 2F, the adhesive waterproof layer 150 and the adhesive plate 140 are positioned on the work surface 110 in the adhesive plate fixing step S23 and the adhesive waterproof layer 150 and the adhesive plate 140 are passed through the adhesive plate 140, The adhesive waterproof layer 150 and the adhesive plate 140 are fixed to the work surface 110 by fastening the fastening members so as to extend to the inside of the adhesive 130. For reference, the illustration of the first adhesive layer 134 is omitted in Figs. 2E to 2H for the sake of simplicity.

With reference to Fig. 3, the adhesive plate 140 will be described in more detail. 3 is a plan view of an adhesive plate 140 applied to a waterproof lining method according to an embodiment of the present invention.

The adhesive plate 140 has a substantially plate shape made of a metal such as stainless steel. The adhesive plate 140 can improve the structural stability of the waterproof lining structure and prevent the waterproof lining structure from being easily peeled off. The waterproof layer 160 can be more easily fixed using a magnet or the like. FIG. 3 shows an example of a roughly square adhesive plate 140, but the shape of the adhesive plate 140 may be various shapes such as a circular shape or a polygonal shape.

The adhesive plate 140 may have a larger area than the groove 130. Accordingly, the adhesive waterproof layer 150 and the like can be stably fixed to the work surface 110 having the groove 130.

The adhesive plate 140 includes a first portion 141 fixed to the work surface 110 and a second portion 142 to which the adhesive waterproof layer 150 and / or the waterproof layer 160 are fixed.

The first portion 141 is formed at an edge portion of the adhesive plate 140 and the second portion 142 is formed at a central portion and is protruded to one side from the first portion 141. The adhesive plate 140 is positioned so that the second portion 142 protruding from the first portion 141 is separated from the work surface 110 when the adhesive plate 140 is fixed to the work surface 110. Accordingly, a certain space is formed between the work surface 110 and the second portion 142, and the adhesive waterproof layer 150 can be positioned in this space.

The first portion 141 may have a plurality of protrusions 141a located along the edge of the second portion 142 so as to be adhered to the working surface 110 side and constituting a gear- . The plurality of protrusions 141a may include a cutout 141b between the protrusions 141a so that the protrusions 141a may be physically separated from each other. The cutout 141b has a trapezoidal shape in which the width of the cutout 141b gradually increases from the edge of the first portion 141 to the edge of the first portion 141, Lt; / RTI >

Since the plurality of protrusions 141a are physically separated by the cutouts 141b, the plurality of protrusions 141a can be easily folded. When the work surface 110 is uneven, the boundary BP (the portion adjacent to the second portion 142 or the cutout portion 141b adjacent to the second portion 142 at the protruding portion 141a) The height of each of the protrusions 141a can be adjusted by adjusting the angle formed by the second portion 142 and the second portion 142. Therefore, Specifically, the height of the projecting portion 141a can be adjusted according to the folding angle of the projecting portion 141a.

Thereby, irrespective of the thickness of the work surface 110 or the other structure or layer (for example, the first adhesive layer 134 in FIG. 2D) located between the work surface 110 and the adhesive plate 140, (140) can be stably positioned.

The second portion 142 is provided with a fastening hole 142a through which the fastening member 144 can be fastened and an outlet for allowing the adhesive waterproof layer 150 or the waterproof layer 160 to be leaked when the adhesive or waterproofing material is melted by high- And a hole 142b is provided. When the adhesive water repellent layer 150 is provided, the substances of the adhesive water repellent layer 150 and / or the waterproof layer 160 may flow out to each other through the outflow hole 142b and contact with each other. When the adhesive waterproof layer 150 is not provided, the material of the waterproof layer 160 may flow out to the work surface through the outlet hole 142b. At this time, since the second portion 142 does not protrude at the portion where the fastening hole 142a is located, the corresponding portion can be positioned on the same surface as the first portion 141. As a result, the portion where the fastening hole 142a is located is brought into close contact with the work surface 110 so that the fastening member 144 can be stably positioned.

In the drawing, it is illustrated that the fastening hole 142a is positioned at the center and fastened using one fastening member 144 to simplify the structure and fastening structure of the adhesive plate 140 and to stabilize the fastening structure. However, the present invention is not limited thereto, and the number, position, etc. of the fastening holes 142a may be variously modified.

And a plurality of the outflow holes 142b in the second portion 142 may be evenly distributed over the entire area. The adhesive waterproof layer 150 can be uniformly flowed out through the outflow hole 142b when the adhesive waterproof layer 150 is melted by the subsequent thermal fusion so that the adhesive waterproof layer 150 can smoothly adhere the adhesive plate 140 to the work surface 110, To be stably bonded.

2E, the adhesive waterproof layer adhesive plate 140 is placed on the work surface 110, and in this state, the fastening member 144 is fastened to the fastening hole 142a as shown in FIG. 2F, (130). The adhesive waterproof layer adhesive plate 140 is physically fixed.

Various structures known as the fastening member 144 can be used. In FIG. 2F, a screw thread is used as the fastening member 144. However, the present invention is not limited thereto, and the anchor bolt as shown in Fig. 4 (a) or the strong anchor bolt as shown in Fig. 4 (b) can be used as the fastening member 144. [ In addition, you can use ankle block anchor, set anchor, etc.

In the figure, positioning the adhesive waterproof layer 150 between the work surface 110 and the adhesive plate 140 (particularly the second portion 142) when positioning the adhesive plate 140 on the work surface 110 .

The adhesive waterproof layer 150 may include various materials that are waterproof and can adhere the adhesive plate 140 to the work surface 110. For example, the adhesive waterproof layer 150 may include a main component (for example, 50 wt% or more) of a polymer resin. In the present embodiment, the adhesive waterproof layer 150 may include a polymer resin as a main component (for example, 50 wt% or more). Polymeric resins include ethylene vinyl acetate (EVA), linear low density polyethylene (LLDPE), polyethylene (PE), ethylene copolymerized bitumen (ECB), vinylacetate VA), and the like. And the adhesive water repellent layer 150 may include additives capable of improving various properties.

When the adhesive waterproof layer 150 is positioned together with the adhesive plate 140, the waterproof function and adhesion property can be improved by the adhesive waterproof layer 150. However, the present invention is not limited thereto. That is, since the adhesive waterproof layer 150 is not essential, it is also possible to simplify the structure, the process, and the like by placing only the adhesive plate 140 without the adhesive waterproof layer 150.

Next, as shown in FIG. 2G, in the waterproof layer aligning step S24, the waterproof layer 160 may be positioned on the front surface of the adhesive plate 140. FIG.

At this time, the waterproof layer 160 may contain a different material than the adhesive waterproof layer 150 or may be different in composition from the adhesive waterproof layer 150. For example, the waterproof layer 160 may further include at least one of ozone, antimicrobial, and flame retardant materials, or may include a higher content than the adhesive waterproof layer 150. The adhesive waterproofing layer 150 may be composed of a minimum amount of material for fixing the adhesive sheet 140 because the adhesive waterproofing layer 150 is partially located only on the portion where the adhesive sheet 140 is located, And is formed over the working surface 110 to which the lining method is to be applied so that it has better characteristics than the adhesive waterproof layer 150.

For example, the waterproof layer 160 may include a main component (for example, 50 wt% or more) of a polymer resin like the adhesion waterproof layer 150. In the present embodiment, the adhesive waterproof layer 150 may include a polymer resin as a main component (for example, 50 wt% or more). The polymer resin may include EVA, LLDPE, PE, ECB, VA, and the like. And the waterproof layer 160 may include additives that can improve various properties.

At this time, the waterproof layer 160 may further include an antimicrobial material or may include more water than the adhesive waterproof layer 150. For example, ethylene vinylacetate may be used as the antimicrobial substance. For example, the waterproof layer 160 may include EVA and LLDPE in an amount of 40 to 60 parts by weight based on 100 parts by weight of the waterproof layer 160, respectively. At this time, if the EVA is less than 40 parts by weight or the LLDPE exceeds 60 parts by weight, the antibacterial property may not be sufficient. If the EVA is more than 60 parts by weight or the LLDPE is less than 40 parts by weight, the waterproof property may not be excellent. However, the present invention is not limited thereto and various modifications are possible. On the other hand, ethylene vinyl acetate may contain 40 to 60 parts by weight of regenerated ethylene vinyl acetate.

However, the present invention is not limited thereto, and other materials may be used as the antibacterial material, and the content of the antibacterial material may be varied.

Alternatively, the waterproof layer 160 may additionally include or contain more flame retardant material than the adhesive waterproof layer 150. Thus, when the waterproof lining structure is installed in a place where a fire can occur, it can prevent the fire from moving.

As a flame retardant, various materials can be used. Examples of the flame retardant include black carbon, a bromine-based flame retardant, a phosphorus-based flame retardant (eg, OP-930), a liquid phase flame retardant (eg, SPL- At least one of the flame retardants may be used. Black carbon is inexpensive and has excellent flame retardancy. And the waterproof layer 160 including black carbon has a black or black color and can have excellent appearance.

The flame retardant may be included in an amount of 1 to 30 parts by weight based on 100 parts by weight of the waterproof layer 160 as a whole. If the flame retardant is contained in an amount of less than 1 part by weight, the flame retardancy may not be sufficient. If the flame retardant exceeds 30 parts by weight, the content of the other components may not be sufficient for the waterproof property. The flame retardant may be 1 to 10 parts by weight based on 100 parts by weight of the waterproof layer 160. However, the present invention is not limited thereto, and other materials may be used as the flame retardant, and the content of the flame retardant may vary.

Alternatively, the waterproof layer 160 may further include or contain more ozonized material than the adhesive waterproof layer 150. As a result, the waterproof lining structure can be prevented from deteriorating due to the strong oxidizing power of ozone.

As the ozone material, various materials can be used. For example, a thermoplastic elastomer can be used.

The ozone material may be included in an amount of 50 to 99 parts by weight based on 100 parts by weight of the waterproof layer 160 as a whole. If the content of the ozone substance is less than 50 parts by weight, the ozone characteristic may not be sufficient. If the content of the ozone substance exceeds 99 parts by weight, the content of the other ingredients for the waterproof property may not be sufficient. However, the present invention is not limited thereto, and other materials can be used as the ozone material, and the content of the ozone material can also be changed. For example, when the waterproof layer 160 contains ozone, the waterproof layer 160 may contain 0 to 25 parts by weight of EVA, 0 to 25 parts by weight of LLDPE, 1 to 2 parts by weight of additives (colorant, stabilizer, etc.) ).

However, the present invention is not limited thereto, and the waterproof layer 160 may include the same material as the adhesive waterproof layer 150.

Various methods known in the art or in methods for aligning or securing the waterproof layer 20 to a particular location may be used. In this embodiment, a method of aligning or fixing the waterproof layer 160 using the strong magnet 170 is exemplified. When the strong magnet 170 is attached to the position corresponding to the above-described adhesive plate 140, the waterproof layer 160 is caught between the adhesive plate 140 and the strong magnet 170, and thus can be fixed. However, the present invention is not limited thereto.

Next, as shown in FIG. 2H, the adhesive waterproof layer 150 and the waterproof layer 160 are attached to the work surface 110 by thermal fusion. Various methods known as heat fusion can be used, and the present invention is not limited thereto. As an example, thermal fusion can be performed using high frequency. A part of the adhesive waterproof layer 150 flows out through the outlet hole 142b of the adhesive plate 140 to fill the outlet hole 142b so that the adhesive plate 140 can be adhered to the work surface (110).

The waterproof lining structure 100 thus fabricated has a groove 130 formed in the work surface 110, an adhesive material 132 filled in the groove 130, An adhesive layer 140 fixed to the work surface 110 by the member 140 and an adhesive waterproof layer 150 positioned between the adhesive layer 140 and the work surface 110, And a waterproof layer 160 positioned above the surface 110.

Then, in the joint fusion step S26, the joint between the waterproof lining structure 100 and the waterproof lining structure 10- is fused. In this embodiment, the waterproof layer 160 is melted and bonded to each other using a high-frequency wave or the like at the joint portion, so that the joint portion can be fusion-bonded. As described above, the seams can be joined by heat fusion without using any adhesive, so that the construction process can be simplified and the plurality of waterproof lining structures 100 can be stably integrated.

According to the present embodiment, the groove 130 is formed on the work surface 110 and the fastening member 144 fastened to the adhesive plate 140 together with the filler 132 is positioned in the groove 130, 140 can be stably fixed and problems such as breakage and leakage which may occur due to cracks or the like that may occur when the fastening member 144 is fastened can be solved. Thus, the structural stability and waterproof characteristics of the waterproof lining structure 100 can be improved.

The waterproof lining method and structure according to another embodiment of the present invention will be described in detail with reference to the accompanying drawings. Since the above description can be applied to the same or extremely similar parts as the above description, the detailed description will be omitted and only the different parts will be described in detail. It is also within the scope of the present invention to combine the above-described embodiments or variations thereof with the following embodiments or modifications thereof.

FIG. 5 is a cross-sectional view illustrating a waterproof lining method and structure according to another embodiment of the present invention, and FIG. 6 is a perspective view illustrating a waterproof layer included in the waterproof lining structure shown in FIG.

5 and 6, in this embodiment, the waterproof layer 160 includes a fleece cloth 162, a waterproofing material layer 164 positioned on one surface of the fleece cloth 162, And a waterproof sheet including a mesh layer 166 having a mesh structure.

The fibrillated fiber 12 can play a role of improving the tensile performance, elongation and the like of the waterproof sheet while supporting the waterproofing material layer 164 and the mesh layer 166 located on both sides. For example, when the fibrillated fiber 12 is made of a nonwoven fabric, the waterproofing material layer 164 can be stably formed on the fibrillated fiber 12 by a method such as impregnation or coating, and the mesh layer 166 can be stably . The nonwoven fabric of the fibrillated fibers 12 exposed through the mesh structure of the mesh layer 166 can be prevented from sliding on the work surface. The fibrillated fiber 12 may be composed of various fibers such as natural fiber, polyester, polyethylene terephthalate, and polypropylene. However, the present invention is not limited thereto, and the fibril 12 may have various shapes, materials and the like.

The waterproofing material layer 164 formed on one surface of the fibrillated fiber 12 may be a waterproofing material of the waterproofing layer 160 described with reference to FIGS. 1 to 4, and thus a detailed description thereof will be omitted.

The waterproof material layer 164 may be formed in the fibrillated fiber 12 by impregnating the fibrillated fiber 12 with the composition including the polymer resin, ultraviolet stabilizer, antibacterial agent, and the like. However, the present invention is not limited thereto, and the waterproofing material layer 164 may be formed by various other methods.

Although not shown in the drawing, a protective film, a release film, or the like may be formed on the waterproofing material layer 164. The protective film is made of a material that protects the waterproofing material layer 164, and may be formed by vapor deposition, coating, or the like. When the waterproofing material layer 164 is protected by the protective film, the waterproofing material layer 164 is prevented from being damaged, and the waterproofing property can be maintained. Also, even if the waterproofing material layer 164 is cleaned after the waterproofing lining, it can be prevented from being damaged. The release film serves to prevent damage to the waterproofing material layer 164 during transportation and storage, and can be removed by peeling after the lining application. When a protective film and a release film are formed together, a protective film may be formed on the waterproofing material layer 164, and a release film may be formed on the protective film. Other various layers may be placed on the waterproofing material layer 164.

A mesh layer 166 having a mesh structure is fixed to the other surface of the fibril 12. The mesh layer 166 includes a plurality of warp yarns 166a spaced apart from one another and a plurality of warp yarns 166b spaced apart from one another to intersect the weft yarns 166a. In the mesh layer 166, an opening 166c is formed between a plurality of spaced weft yarns 166a and a plurality of spaced apart warp yarns 166b to form a mesh structure. The fibril 12 is exposed through the opening 166c formed in the mesh layer 166. [

The other surface of the fibril 12 on which the mesh layer 166 having the mesh structure is located is a surface to be brought into contact with the adhesive applied on the work surface. When the mesh layer 166 having the mesh structure is disposed on such a surface, the contact area with the adhesive can be increased and the adhesive is stably positioned in the opening 166c formed by the warp 166a and the warp 166b, The adhesion between the sheet and the work surface can be improved. As a result, the waterproof sheet can be stably bonded to the work surface to improve the adhesive property, and it is also helpful to prevent cracks, thereby improving the waterproof property.

At this time, the weft yarn 166a and the warp yarn 166b are orthogonal to each other, and the mesh layer 166 may have a plain weave structure. In this case, since the intersections of the warp yarns 166a and the warp yarns 166b are large, the mesh layer 166 is hardened and the strength and the adhesive strength of the mesh layer 166 can be improved. However, the present invention is not limited thereto, and the mesh layer 166 may have various fabric structures.

The weft yarns 166a or the warp yarns 166b of the mesh layer 166 may include glass fibers, aramid fibers, carbon fibers, jute fibers, coconut fibers, polyethylene fibers, and the like. Glass fiber, aramid fiber, carbon fiber, jute fiber, coconut fiber, polyethylene fiber and the like can have excellent strength even with a thin thickness. Therefore, the opening 166c can be formed in a sufficient area, the strength of the waterproof sheet can be improved, and the adhesion property between the work surface and the waterproof sheet can be improved. However, the present invention is not limited thereto, and the weft yarn 166a or the warp yarn 166b of the mesh layer 166 may include various other materials.

The thickness of the mesh layer 166 (or the thickness of the weft yarn 166a or the warp yarn 166b) may be 0.1 mm to 5 mm. If the thickness of the mesh layer 166 is less than 0.1 mm, the effect of the mesh layer 166 is not sufficient and the strength of the mesh layer 166 may be insufficient. If the thickness of the mesh layer 166 exceeds 5 mm, the material cost due to the mesh layer 166 may increase or the adhesion property may be deteriorated due to the mesh layer 166. However, the present invention is not limited thereto, and the thickness of the mesh layer 166 may have a different value.

Alternatively, the thickness of the mesh layer 166 may be equal to or less than the thickness of the waterproofing material layer 164. This is because the waterproofing material layer 164 has sufficient thickness for waterproofing and the mesh layer 166 is thick enough to enhance the adhesion property.

The distance L1 between the plurality of weft yarns 166a or the distance L2 between the plurality of warp yarns 166b may be greater than the thickness of the mesh layer 166. [ In one example, the distance L1 between the plurality of weft yarns 166a or the distance L2 between the plurality of warp yarns 166b may be 2 mm to 30 mm. If the distance L1 between the plurality of weft yarns 166a or the distance L2 between the plurality of warp yarns 166b is less than 2 mm, the area of the opening 166c is not sufficient and the manufacturing cost of the mesh layer 166 is not high . When the distance L1 between the plurality of weft yarns 166a or the distance L2 between the plurality of warp yarns 166b exceeds 30 mm, the mesh layer 166, which improves the contact area with the working surface, May not be sufficient. However, the present invention is not limited thereto, and the distance L1 between the plurality of weft yarns 166a and the distance L2 between the plurality of warp yarns 166b may have different values.

For example, when the area of the mesh layer 166 is 100%, the total area ratio of the opening 166c to the area of the mesh layer 166 may be 50% to 99%. If the ratio is less than 50%, the area of the opening 166c is not sufficient and the manufacturing cost of the mesh layer 166 may be expensive. If the ratio exceeds 99%, the effect of the mesh layer 166 which improves the contact area with the work surface and improves the adhesion property may not be sufficient. However, the present invention is not limited thereto, and the ratio of the total area of the opening 166c to the area of the mesh layer 166 may have a different value.

The mesh layer 166 may be 3 to 8 parts by weight based on 100 parts by weight of the waterproofing material layer 164. The effect of the mesh layer 166 can be realized without deteriorating the properties of the waterproofing material layer 164 in such a weight portion. However, the present invention is not limited thereto, and the weight portion of the mesh layer 166 may have a different value.

The mesh layer 166 may be integrally secured to the other surface of the fibril 12 by various methods. For example, the fibrillated fiber 12 and the mesh layer 166 can be fixed by needle punching with a large platen with a needle. Then, the fibrillated fiber 12 and the mesh layer 166 are fixed in contact with each other without using any adhesive, so that the manufacturing process of the waterproof sheet having the mesh layer 166 can be simplified and the process cost can be reduced have. At this time, if the fibrillated fiber 12 is made of nonwoven fabric, the fixing stability of the fibrillated fiber 12 and the mesh layer 166 can be further improved when needle punching is used. However, the present invention is not limited thereto. For example, the fibrillated fiber 12 and the mesh layer 166 may be fixed using a separate adhesive or the like. In this case, an adhesive that contacts the fibrillated fibers 12 and the mesh layer 166 may be located therebetween.

In this embodiment, it is illustrated that the mesh layer 166 is disposed on the other surface of the fibrillated fiber 12 without a separate layer. The fibrillated fiber 12 is exposed to the opening 166c of the mesh layer 166 to stably fix the fibrillated fiber 12 and the mesh layer 166 and prevent the waterproof sheet from slipping on the working surface. However, the present invention is not limited thereto, and a separate waterproof layer having the same or different material or composition as that of the waterproofing material layer 164 may be disposed between the other surface of the fibril 12 and the mesh layer 166. As a result, the waterproof property can be further improved. Various other variations are possible.

The waterproof sheet according to the present embodiment may be positioned on the adhesive plate 140 with the mesh layer 166 positioned on the working surface 110. Then, it can be formed while filling the opening 166c of the mesh layer 166 which has passed through the outflow hole 142b of the adhesive plate 140 during the heat fusion. Thus, the adhesive property between the adhesive sheet 140 and / or the work surface 110 and the waterproof sheet can be improved, thereby improving the waterproof property of the waterproof sheet. Since the material of the waterproofing material layer 164 of the waterproof sheet is stable, it is convenient to construct, and noxious gas is not generated during construction, thereby preventing a safety accident. Also, the physical strength of the mesh layer 166 can be improved, and problems such as peeling of the waterproof layer 160 due to an external impact or the like can be minimized. However, the present invention is not limited thereto, and the structure of the waterproof sheet may be variously modified.

7 is a cross-sectional view illustrating a waterproof lining method and structure according to another embodiment of the present invention.

Referring to FIG. 7, in this embodiment, a second adhesive layer 136 is positioned between the adhesive plate 140 and the waterproof layer 160. The waterproof lining structure is formed by applying a second adhesive layer 136 on the adhesive plate 140 and the work surface 110 in a waterproof layer alignment step (see FIG. 2G) in which the waterproof layer 160 is placed on the adhesive plate 140 And then placing the waterproof layer 160 thereon.

The second adhesive layer 136 may be applied over the work surface 110 as well as over the adhesive plate 140 as a whole. The second adhesive layer 136 may be formed by applying the above-described waterproof adhesive composition such as the first adhesive layer 134 or the adhesive 132.

According to the waterproof lining method of the present embodiment, the second adhesive layer 136 can be formed between the work surface 110 and the waterproof layer 160 to tightly bond the waterproof layer 160 and the work surface 110. As a result, the waterproof sheet can be adhered to the work surface 110 in a state where the adhesion strength and water tightness between the second adhesive layer 136 and the work surface 110 are excellent. As a result, secondary cracks hardly occur due to changes in external temperature, humidity, or external impact, and the strength of the waterproof lining construction can be improved without additional reinforcement measures.

5, when the waterproof sheet 160 is used as the waterproof layer 160, the surface of the waterproof sheet on which the mesh layer 166 is located is positioned toward the second adhesive layer 136. In this case, Then, the surface of the waterproof sheet where the mesh layer 166 is located and the second adhesive layer 136 are attached to each other. At this time, the second adhesive layer 136 is formed while filling the opening (reference numeral 166c in Fig. 1) of the mesh layer 166, and the bonding area between the second adhesive layer 136 and the waterproof sheet is wide. As a result, the adhesive property between the second adhesive layer 136 and the waterproof layer 160 can be improved.

In the waterproof lining method and structure according to the present embodiment, the waterproof adhesive composition is applied directly to the wet and wet work surface 110 without a separate drying step to form a first adhesive layer (reference numeral 134 in FIG. 2B) And / or the second adhesive layer 136 can be formed. Therefore, it is possible to reduce the construction time by reducing the time for drying, and the construction cost can be reduced by reducing the cost of using the product for drying.

Features, structures, effects and the like according to the above-described embodiments are included in at least one embodiment of the present invention, and the present invention is not limited to only one embodiment. Further, the features, structures, effects, and the like illustrated in the embodiments may be combined or modified in other embodiments by those skilled in the art to which the embodiments belong. Therefore, it should be understood that the present invention is not limited to these combinations and modifications.
