Description

Waterproofing method and structure using complex aluminum tape and complex rubbur asphalt sheets, complex rubbur asphalt sheets}

The present invention relates to a composite waterproofing method and structure using a composite aluminum tape and a composite rubber asphalt sheet, and a composite rubber asphalt sheet, in detail, the joint portion between the composite rubber asphalt sheet during waterproof construction, such as rooftop concrete or parking lot of the building Non-exposure or exposure waterproofing method and structure to prevent leakage by increasing the bonding force between urethane coating material applied on the upper part of the composite aluminum tape and the composite rubber asphalt sheet, at the same time by simply and quickly thermally bonding by using a tape. The present invention relates to a composite rubber asphalt sheet.

In general, civil engineering structures such as rooftops, basement outer walls, and underground car park concrete layers are made of concrete, and structures are cracked by volume changes and repeated vibrations and proceed further after cracking. Therefore, not only environmental problems such as maintaining a pleasant living environment for real residents, but also corrosion of reinforcing steel and steel frame due to leakage, neutralization, freezing and melting, invasion of harmful substances, etc., lead to a decrease in the lifespan of construction and civil structures.

Waterproofing construction to prevent this problem is widely used as a sheet waterproofing material, coating film waterproofing material and the like. However, in the case of sheet waterproofing material, it is difficult to melt by using a heating torch during construction, long construction time, risk of burns during construction, and incomplete joint seam, there is always a risk of leakage, which is the biggest cause of sheet waterproofing. In addition, as the coating film waterproofing material is applied by spray and roller, the construction is simple and the construction speed is fast, but it is difficult to produce a uniform thickness, and the hardened or dried waterproof layer is adhered to the surface of the structure to prevent cracking. There is a problem that the leak occurs due to the tearing and breaking low followability.

In order to solve such a conventional problem, recently, the composite waterproof method using a coating material and a waterproof sheet by using a combination of the coating material and the waterproof sheet has been widely used. In the composite waterproofing method, an improved asphalt waterproof sheet having a low cost but excellent waterproof performance is widely used as a waterproof sheet, and is classified into a urethane-based coating material and a asphalt asphalt coating material which are inexpensive.

However, there is a defect in the waterproof layer due to the damage between the inter-sheet joint area and the improved asphalt waterproof sheet due to the coating material used. The reason is that it was difficult to maximize the advantages of the fundamental composite waterproofing method by using a heterogeneous material urethane-based coating material and solvent-based asphalt one-component type.

In other words, in the case of the improved asphalt waterproof sheet and the urethane coating material composite method, it is difficult to integrate between asphalt and urethane, so that non-woven fabric is laminated on the improved asphalt, and the upper part of the waterproof sheet and the joint part are urethane coated. As asphalt and urethane coating materials have low mutual affinity, they are not integrated and are easily separated and there is a risk of water leakage.In addition, the solvent contained in the urethane coated on the top of the waterproof sheet penetrates into the non-woven fabric. The performance problem has been raised, and also the problem of discoloration in which the asphalt melted in the solvent penetrates the urethane surface applied to the upper part after a certain time passes and blackens.

On the other hand, the most important part to prevent leakage during waterproof construction using the composite waterproof method is the joint between the waterproof sheet and the sheet. If the construction of the joint is not done properly, the joint may be cracked or detached, resulting in water leakage.

9 is a cross-sectional view of the joint portion construction according to the conventional embodiment, the prior art including the illustrated embodiment is a joint between the improved asphalt waterproof sheet overlapping the waterproof sheet in the upper and lower sides, or applied to the lower side after a certain interval spaced apart The gap is filled with a material similar to that of the waterproof material or the adhesive component to be bonded, or the adhesive is applied to the lower part or the upper part after the joint is bonded to connect the waterproof sheets.

However, the method of forming an adhesive layer having a predetermined thickness at the bottom after overlapping or tasting the waterproof sheets has a problem in that the surface is not flat because the step is caused by the joint part of the waterproof sheet.

In order to prevent this, the neighboring waterproof sheets are spaced apart by a certain distance, and then the gap is filled with a material similar to that of the waterproofing material or adhesive component, and then bonded and constructed to protect the adhesives filled in the joints between the waterproofing materials. In this case, there is a problem of leaking through such a construction site due to detachment due to the problem of integration with the urethane applied to the upper part along with the time-consuming problem.

On the other hand, there is a method for shortening the time taken to reinforce the upper part of the joint part, and partially reinforces the joint part adhesive force between the waterproof sheets. 10 is a cross-sectional view of a construction using a joint tape which is constructed on an upper portion of a joint according to the related art.

The conventional joint tape as shown is a simple tape combined with adhesive and fabric paper, and is vulnerable to deformation due to climate change, and is basically not waterproof. Due to the urethane coating material and the heterogeneous material is difficult to integrate, there is a structural problem that there is a problem of leakage through cracking and detachment or lifting phenomenon through the construction site during the construction of the urethane coating material.

Hereinafter, the configuration and the operation of the embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

The waterproof structure of the present invention provides a composite rubber asphalt sheet having a urethane material formed thereon to prevent cracking, detachment, and lifting by increasing the unity with the urethane coating material applied by the non-exposure method or the exposure method. In addition, the joint portion between the composite rubber asphalt sheet is provided with a composite aluminum tape formed with a urethane material to waterproof.

The joints between neighboring composite rubber asphalt sheets spaced at regular intervals for insulation purposes during such waterproof construction are filled with adhesives having the same physical properties as those of the composite rubber asphalt sheets, that is, rubber asphalt-based coating materials, and filled with neighboring composite rubbers. The asphalt sheets are insulated and bonded together.

After that, a composite aluminum tape is attached to the upper portion of the adhesive to cover the upper portion of the insulation and the two-side composite rubber asphalt sheet without a separate reinforcing structure. When the composite aluminum tape is used, the waterproof construction can be completed quickly, and there is no effect of advancing the air, and there is no heterogeneity with the urethane applied to the top, thereby achieving perfect waterproof construction.

That is, in the waterproof construction method according to the present invention, the parts to be constructed under the urethane coating material are all composed of a composite aluminum tape and a composite rubber asphalt sheet, and thus the urethane coating material and the urethane-based material are integrated at the upper interface to crack, detach, and lift. The phenomenon is prevented.

Hereinafter, the waterproof structure of the present invention will be described in more detail.

1 is a cross-sectional view illustrating a waterproof structure of a joint part during non-exposure construction according to an embodiment of the present invention, and FIG. 2 is a flowchart illustrating a construction procedure of a non-exposure waterproof method according to an embodiment of the present invention.

As shown, the waterproof laminated structure of the present invention includes a facility concrete 1 such as a building forming a lower portion thereof; A primer 2 applied to the front of the concrete; A composite rubber asphalt sheet 3 of which a plurality of the upper layers are arranged on the primer to be self-contained and made of urethane material; An adhesive 4 filled in a joint portion between neighboring composite rubber asphalt sheets 3; A composite aluminum tape 5 bonded to the adhesive upper portion filled with the joint portion and overlapping a portion of the upper surface of the neighboring composite rubber asphalt sheet; A urethane coating material 6 applied to the composite rubber asphalt sheet and the composite aluminum tape upper surface; It is laminated | stacked structured; mortar 7 apply | coated on the urethane coating-film material 6 upper part.

The non-exposed waterproof method construction procedure of the present invention having the laminated structure as described above will be described below.

The construction sequence of the present invention is a step of pre-treating the flat and completely dry so that there is no uneven surface, sharp surface formed on the upper base surface of the concrete (1) (S100);

After applying the primer (2) to the concrete upper base surface (S101);

Thereafter, a plurality of composite rubber asphalt sheets 3 produced or chopped to a predetermined standard according to the waterproof construction area to be installed on the primer 2 are arranged to be tasted and attached to each other (S102);

After the step (S103) of filling the adhesive (4) in the gap formed by being spaced apart a predetermined interval between the adjacent composite rubber asphalt sheet (3);

After attaching the composite aluminum tape (5) on the joint portion formed by filling the composite rubber asphalt sheet and the adhesive and heat-sealed to integrate (S104);

After applying the front surface of the composite rubber asphalt sheet and the composite aluminum tape to the urethane coating material (6) (S105);

After the urethane coating material 6 is dried (S106) to apply a mortar (7) on the top.

Specifically, each step will be described.

First, there is no uneven surface formed on the upper base surface of the concrete (1), so that there is no flat surface and dry completely to pretreatment work.

After the primer is formed on the upper surface of the concrete (2) is formed. The amount to be applied is applied to about 0.1 ~ 0.4 / m ² . If less than this, the adhesive strength with the composite rubber asphalt sheet to be installed on the top is weak, if more than this is too thick because there is a problem that the primer can be detached. Preferable application amount is about 0.3 / m <^2> .

The primer material to be used is thinly coated using the same or similar material as the rubber asphalt material of the composite rubber asphalt sheet to be installed on the top. In general, the primer material is treated with the same or similar to the rubber asphalt sheet or rubber asphalt coating material which is constructed on the upper part, because the rubber asphalt sheet or rubber asphalt coating material, which is a kitchen water layer formed on the concrete under the primer, is different from each other. Due to the waterproofing may be detached or lifted during construction, it is a pre-treatment process is painted with a thin film to prevent this phenomenon.

Thereafter, the primer 2 is constructed by arranging a plurality of composite rubber asphalt sheets 3 produced or cut to a predetermined standard according to the waterproof construction area to be constructed. At this time, the composite rubber asphalt sheet to be used is directly adhered to the upper surface of the concrete is formed by primers pretreated in the lower portion.

The joints between neighboring composite rubber asphalt sheets 3 are spaced apart at regular intervals during the flavoring. Spacing is about 3 ~ 7mm. If the gap is narrower than this, the adhesive strength by the adhesive is lowered, the thermal expansion due to the climate change can not cope with elasticity, the collision with each other can be raised to break the joint part. In addition, if the gap is larger than this, there is a structural problem that a lot of adhesives, structural stability during heat shrinkage due to climate change can be detached from the composite rubber asphalt sheet due to the leakage can occur. The preferred gap is 5mm, which is the best gap against leakage and climate change.

Thereafter, the gap space portion formed to be spaced apart from each other by the adjacent composite rubber asphalt sheet 3 is filled with an adhesive 4 to be impregnated and cured. The filling amount is about 0.3kg / m ² ~ 0.5kg / m ² is applied when the gap is 5mm. Preferably about 0.4kg / m ² is to be applied. If less adhesive is applied, the adhesive strength is lowered. If more adhesive is applied, the adhesive overflows, which leads to unnecessary material waste during construction, and requires an additional removal process to maintain flatness.

The filled adhesive bonds a plurality of composite rubber asphalt sheets laterally to integrate and prevent leakage. In this case, it is preferable to use an adhesive having the same or similar composition as the rubber asphalt material of the composite rubber asphalt sheet. The reason for this is that when the same material is used, it is well integrated with the composite rubber asphalt sheet to prevent detachment or cracking of the joint part, thereby preventing water leakage and increasing the waterproof ability.

In addition, the upper layer structure of the composite rubber asphalt sheet is formed of a urethane material to increase the integrity of the urethane coating material applied on the top to prevent cracking, detachment and lifting phenomenon.

The upper portion of the joint portion formed by filling the composite rubber asphalt sheet and the adhesive as described above attaches the composite aluminum tape 5. When the composite aluminum tape is constructed as described above, it is unnecessary to cover and dry a separate coating material to prevent leakage between the upper surface of the adhesive and the adjacent composite rubber asphalt sheet.

At this time, the adhesive method of the composite aluminum tape is integrated by thermal fusion with the upper surface of the composite rubber asphalt sheet while melting the hot melt constituting the lower layer of the composite aluminum tape when the heating roller, which is a heat fusion mechanism, is heated. This bonding method maximizes the adhesive strength of the composite aluminum tape, and improves the watertight ability to prevent leakage. Therefore, it is possible to prevent desorption or lifting due to climate change.

In addition, the upper layer structure of the composite aluminum tape is formed of a urethane material to increase the unity with the urethane coating material applied to the upper to prevent cracking, detachment and lifting.

After the construction of bonding the upper portion of the adhesive filled between the composite rubber asphalt sheet as described above with a composite aluminum tape, the front surface of the composite rubber asphalt sheet and the composite aluminum tape with a urethane coating material (6).

After the urethane coating material (6) is dried to apply a mortar (7) on top to complete the non-exposure waterproofing method.

3 is a cross-sectional view showing a laminated structure of a composite aluminum tape according to an embodiment of the present invention.

In the accompanying drawings, for convenience of description, a composite aluminum tape is exemplarily shown to have a large thickness between layers, but in reality, the entire thickness is made of a thin film like aluminum foil. As shown, the composite aluminum tape of the present invention is described from the top,

Urethane-based film layer 51;

An aluminum layer 52 which is a tape base material formed under the urethane film layer;

A PET film layer 53 formed below the aluminum layer to reinforce rigidity;

A urethane-based primer layer 54 for increasing adhesion between the upper PET film layer and the lower urethane-based hot melt layer;

It is composed of; a urethane-based hot melt layer 55 is bonded to the asphalt-based waterproof sheet installed in the bottom by a heat fusion method.

The manufacturing procedure of the composite aluminum tape as described above will be described below according to one embodiment.

Step 1-First, dry lamination of the PET (polyester) film and the AL (aluminum) thin film, and then laminate them. In this case, the aging room temperature is 70 to 90 degrees, the time is preferably aged for at least 24 hours. The reason for limiting such a condition is that when the numerical condition is such that the PET film layer and the aluminum layer are well integrated, they do not detach.

Step 2-After mating the aluminum layer and the polyurethane-based film layer of the laminated fabric of PET film layer and aluminum layer and aged. The ripening condition may be the same as the ripening condition of step 1.

Step 3-The primer film is formed on the PET film layer of the laminated fabric through the above 2 steps.

Step 4-Laminate the primer layer and the polyurethane hot melt film of the laminated material through the three steps.

Step 5-Cut the laminated fabric to the required size through the above 4 steps.

In addition, the thickness of the urethane-based film layer 51 is preferably 30 ~ 60㎛, aluminum layer 52 is 25 ~ 50㎛, PET film layer 53 is 50 ~ 100㎛, primer layer 54 is 3 ~ 10㎛ , Urethane-based hot melt layer 55 is 80 ~ 150㎛. With such a thickness ratio distribution, the laminated composite aluminum tape has good durability and watertightness, thereby increasing the durability of the partial insulation joint construction between the improved asphalt waterproof sheets.

The urethane film layer is made of thermoplastic polyurethane (TPU, Temperature polyurethane) has high processability and molding, in particular, the adhesion of the urethane coating material applied to the upper and the solvent constituting the urethane coating agent penetrates in the downward direction asphalt-based Prevents melting the waterproof sheet

The aluminum layer is formed of a thin film of aluminum, such as aluminum foil used for cooking to prevent the deformation of the tape due to heat during heat welding using a heating roller for the lower hot melt layer, shrinkage rate of the tape due to temperature changes in summer and winter To prevent change. In addition, it prevents the tape from corroding and serves as the base material of the tape to increase the joint durability between the composite rubber asphalt sheets.

The PET film layer is made of polyethylene terephthalate (PET), which is one of thermoplastics, and is a low-cost, durable synthetic resin. Polyethylene terephthalate (PET) refers to polyesters in which terephthalic acid and ethylene glycol are saturated. This PET film layer is to prevent the tearing of the aluminum layer which is a thin film in the present invention serves to increase the rigidity.

The urethane-based hot melt layer is a substantial adhesive layer of the composite aluminum tape, and exhibits adhesive strength while melting by heat fusion with the composite rubber asphalt sheet formed at the bottom. At this time, the urethane-based hot melt layer is to strengthen the adhesive strength with the urethane-based film layer of the composite aluminum layer forming the upper layer of the composite rubber asphalt sheet installed on the bottom. Hereinafter, a urethane-based hot melt layer according to an embodiment will be described in detail.

The urethane-based hot melt layer according to the present invention is made of the same material as that of the urethane-based film of the composite aluminum layer forming the upper portion of the composite rubber asphalt sheet, and has quick curing property and rapid curing so that the subsequent waterproofing can be carried out. It has excellent elasticity and good workability under various climatic conditions including winter season. For reference, thixotropic is a liquid near sol (SOL) state during flow, and maintains a gel (GEL) state in which viscosity rises in a stable state. During application, it thins out and becomes smooth. It refers to the property of not flowing down in the coated state. Therefore, it maintains solid form before thermal fusion.

Specific urethane-based hot melt layer is polypropylene glycol-2 is 15 ~ 20 wt%, asphalt 15 ~ 25 wt%, curing accelerator 0.2 ~ 2 wt%, coal refinery 5 ~ 10 wt%, fast drying petroleum solvent 3 ~ 7 wt %, Calcium carbonate 40-50 wt%, the antisettling agent 1-2 wt%, bentonite 1-2 wt%;

Urethane prepolymer; It is mixed and used in the equivalent ratio of 5: 1 ~ 4: 1.

Preferably, the urethane prepolymer is preferably a prepolymer (PrePolymer) containing 3 ~ 4wt% NCO (isocyanate group). Such prepolymers are more easily mixed with the curing agent composition.

The polypropylene glycol is used for the purpose of increasing the elasticity and elongation of the urethane-based hot melt as a thermoplastic material, and it is preferable to use a divalent OH group, and the composition ratio of 15 to 20 wt% is less than 15 wt. It has a disadvantage in that elasticity or elongation falls, and if it is more than 20wt%, it is disadvantageous in price competitiveness and it is difficult to control the reaction ratio by the equivalent-to-equivalent reaction in two-component form.

The asphalt may be used in any of the asphalt and natural asphalt. The reason for the addition of the asphalt is to prevent detachment, shrinkage deformation, breakage, swelling, etc. in the joint part after the waterproofing of the coating film, which occurs when using a different material by using the same material as the asphalt during the waterproofing of the coating film. In addition, the reason for limiting the composition ratio to 15 to 25 wt% is that the adhesion strength with the asphalt material is less than 15 wt%, and if it is more than 25wt%, there is a problem that the elastic force at the low temperature is sharply dropped.

As the curing accelerator, it is preferable to use ammonium giroconium carbonate that is not a toxic regulatory substance. The reason for limiting the composition ratio to 0.2 to 2 wt% is that there is a disadvantage in that the curing rate is very slow when less than 0.2wt, and when it is more than 2wt%, there is a problem that the working time is shortened and the working time is reduced.

The sort pitch is used to disperse and mix polypropylene glycol-2 and asphalt. In addition, the reason for limiting the composition ratio to 5 to 10wt% is that there is a disadvantage in that the mixing is less than 5wt, and when more than 10wt%, there is a problem that the separation (layer separation) phenomenon is accelerated with the raw materials added after manufacture.

The petroleum solvent is good for compatibility with asphalt and polypropylene glycol to lower the viscosity, that is, to be added to improve workability during construction. As the petroleum solvent, it is preferable to use a commercially available aliphatic hydrocarbon system that is a fast-drying petroleum solvent. In addition, the reason for limiting the composition ratio to 3 to 7wt% is that the viscosity is lowered when the work is less than 3wt, there is a problem that the precipitation of the paint is faster if the viscosity is higher than 7wt%.

The calcium carbonate is used as an important sieving pigment that exhibits mechanical properties (tensile strength, tear strength, elongation), and is used for the purpose of securing workability and price competitiveness. It is better to use μm hardwood. In addition, the reason for limiting the composition ratio to 15 to 20 wt% is that the cost competitiveness is weakened when the weight is less than 15wt, and the curing speed is slowed, and when it is more than 20wt%, the viscosity becomes high and problems of precipitation occur.

The antisettling agent is used to prevent sedimentation of the rubber coating asphalt coating material, and may be any polyamide or polyolefin antisettling agent. In addition, the reason for limiting the composition ratio to 1 to 2wt% is that the precipitation phenomenon is faster if less than 1wt, and more than 2wt% has a disadvantage in price competitiveness.

The bentonite is used to give further thixotropy. In addition, the reason for limiting the composition ratio to 1 to 2wt% is that when it is less than 1wt, there is a disadvantage of flowing down during the construction of the wall.

The primer layer is a polyurethane-based adhesive as an organic solvent layer for increasing adhesion between the upper PET film layer and the lower urethane-based hot melt layer. This is a primer used to supplement the direct adhesion between the PET and the urethane is weak, PET and urethane is infiltrated into the primer layer to show a strong binding force.

It is preferable that the composition of a preferable primer layer can use the composition similar or similar to the urethane type hot-melt layer mentioned above. That is, polypropylene glycol-2 is 15-20 wt%, asphalt 15-25 wt%, curing accelerator 0.2-2 wt%, coal refinery 5-10 wt%, fast-drying petroleum solvent 3-7 wt%, calcium carbonate 40 ~ 50 wt%, antisettling agent 1 ~ 2 wt%, Bentonite 1 ~ 2 wt% of the curing agent;

Urethane prepolymer; is used by mixing the composition of the equivalent ratio of 5: 1 ~ 4: 1 to enhance the adhesion between the upper PET film layer and the lower urethane-based hot melt layer.

For descriptions such as limiting elements of other composition elements, refer to the description of the hot melt layer.

Figure 4 is an exemplary cross-sectional view showing a laminated structure of a composite aluminum tape according to another embodiment of the present invention,

The present invention also forms an adhesive layer of the polyester (PET) or polypropylene (PP) nonwoven layer 56 on top of the aluminum layer so that the urethane film layer is more firmly adhered to aluminum, and thus the adhesive force with the urethane coating material applied to the top. Can be configured to increase.

At this time, the thickness of the nonwoven fabric layer 56 is sufficient to form about 40 ~ 70㎛ slightly thicker than the urethane-based film layer.

The composite aluminum tape of the thin film having the laminated structure as described above is a joint between the composite rubber asphalt sheet while the urethane-based melt is melted by heat fusion to the composite rubber asphalt sheet when applied to the composite waterproofing method consisting of the composite rubber asphalt sheet and the urethane liquid coating material. It improves the bonding performance and integrates the waterproof layer when urethane is applied to the front surface of the composite rubber asphalt sheet, including the upper part of the composite aluminum tape, so that no leakage occurs even for a long time and the waterproof construction is easily improved. That is, the composite aluminum tape according to the present invention exhibits a uniform and excellent bonding force with respect to the entire joint.

Figure 5 is an exemplary cross-sectional view showing a laminated structure of the non-exposed composite rubber asphalt sheet according to an embodiment of the present invention.

As shown, the laminated structure of the non-exposed composite rubber asphalt sheet includes a self-adhesive improved rubber asphalt layer 31 constituting a lower layer; It consists of a composite aluminum sheet layer 32 forming a top layer. Of course, since the self-adhesive improved rubber asphalt layer 31 lowered the release paper or release film is formed before construction is a natural configuration.

The self-adhesive improved rubber asphalt layer 31 is composed of 55 to 65 wt% asphalt, styrene-butadiene-styrene (SBS) rubber 5 to 15 wt%, calcium carbonate 15 to 25 wt%, process oil 5 to 10 wt% do.

The straight asphalt may be used as a general straight asphalt or other asphalt, straight asphalt is the main material of the thermoplastic adhesive rubber asphalt coating material as a material for the rubber asphalt coating film is less than 55wt% problems of rubberization of the asphalt and poor penetration And, if more than 65wt% composition is because the rubber asphalt properties are deteriorated.

The styrene butadiene styrene rubber is a synthetic rubber obtained by copolymerizing butadiene and styrene, and has excellent chemical resistance, aging resistance, weather resistance, abrasion resistance, and heat resistance as compared with natural rubber. In addition, the reason for the composition as described above is that when the composition is less than 5wt%, there is a problem that the physical properties of the rubber-based asphalt coating film is lowered, and when the composition is more than 15wt%, there is a problem that the asphalt property of the rubber-based asphalt is lowered.

The calcium carbonate is difficult to manufacture the sheet when the fluidity is less than 15 wt%, and when used in excess of 25 wt% increases the viscosity of the composition and there is a problem that harden the sheet molding.

The process oil may be used at least one selected from aromatic extracts, depth solvent extraction oil, hydrogenated reforming oil. It is preferable to use those process oils whose pour point is -30 degreeC or more. In addition, the reason for limiting the composition ratio to 5 to 10 wt% is that the penetrating effect is extremely weak when less than 5wt, and when it is more than 10wt%, the drying speed is slow and the sheet forming time takes a lot, resulting in low productivity.

In addition, the self-adhesive improved rubber asphalt layer is formed to have a thickness of about 1 ~ 3mm was configured to have a durability as a waterproof sheet.

The composite aluminum sheet layer 32 has the same layer structure as the composite aluminum tape, but excludes only the hot melt layer forming the lower portion.

That is, the composite aluminum sheet layer 32 is described from the top,

Urethane-based film layer 321;

An aluminum layer 322, which is a tape base material formed under the urethane film layer;

A PET film layer 323 formed under the aluminum layer to reinforce rigidity;

It is composed of; a urethane-based primer layer 324 for increasing the adhesion of the upper PET film layer and the lower self-adhesive improved rubber asphalt layer.

In addition, the thickness of the urethane-based film layer 321 is preferably 30 ~ 60㎛, aluminum layer 322 25 ~ 50㎛, PET film layer 323 50 ~ 100㎛, primer layer 324 3 ~ 10㎛ to be. When the thickness ratio distribution is such that the integration with the lower self-adhesive improved rubber asphalt layer is not separated well, the integration with the upper urethane coating material due to the adhesion is also good.

The rest of the description is redundant and therefore replaces the description of the composite aluminum tape.

6 is a cross-sectional view showing a joint part waterproof laminated structure at the time of exposure construction according to another embodiment of the present invention, Figure 7 is a flow chart showing the construction sequence of the exposure waterproof method according to another embodiment of the present invention, Figure 8 is a cross-sectional view showing a laminated structure of the exposed composite rubber asphalt sheet according to another embodiment of the present invention.

Exposed waterproofing structure and waterproofing method according to the present invention is almost the same as described in Figures 1 and 3 above. The difference is that the waterproof laminated structure in the exposure method is the primer 2 applied to the concrete one point joint part, unlike the waterproof laminated structure in the non-exposed waterproof method. That is, the primer is formed only in the joint part forming part due to the construction in the partial insulation method.

In addition, the adhesive 4 is applied to the primer upper layer formed on the joint part and the joint part. This adhesive partially insulates the composite rubber asphalt sheet 3 from the lower side. The purpose of the partial insulation is the insulation method that is usually performed in the exposure method to check the repair or leakage.

In addition, unlike the non-exposed waterproof laminated structure, the composite rubber asphalt sheet 3 is adhered to the bottom by an adhesive applied to the upper part of the joint part to which the primer is applied.

To this end, the composite rubber asphalt sheet 3 has a structure that is different from the structure of the self-supporting composite rubber asphalt sheet 3 shown in FIG. 5; An improved rubber asphalt layer 31 constituting an intermediate layer integrated with the nonwoven fabric; It consists of a composite aluminum sheet layer 32 forming a top layer. The structure of the improved rubber asphalt layer 31 and the composite aluminum sheet layer 32 is the same as that described above.

In addition, the upper layer is a mortar (7) and the top coating layer (8) made of a coating for protecting or shielding the top of the urethane coating material (6) is formed. The top coating layer may be purchased by applying a commercial top coating material used in the exposure method. Examples of such a top coating material are acrylic resin 30 to 35wt%, isocyanate 5 to 10wt%, polyol 5 to 10wt%, calcium carbonate 5 to 12wt%, pigment 5 to 12wt%, xylene 25 to 30wt%, solvent 5 to 10wt% A top coating material having a ratio of or a top coating material having similar physical properties may be used.

Here, the coating amount of the top coating material is constructed with 0.4 ~ 0.7kg / m ² . If less than this, it is difficult to protect the upper surface of the urethane coating material, and if more, there is no further effect. The preferred coating amount is applied at 0.5 kg / m ² .

That is, the laminated structure in the exposure waterproof method of the present invention is a concrete (1) forming a lower portion; A primer 2 partially applied only to the portion where the concrete upper one-point joint part is to be formed; An adhesive 4 applied to the upper part of the primer first, and the composite rubber asphalt sheet 3 is secondly filled in the joint part after construction; A plurality of constructions are arranged on top of the concrete, the non-woven fabric formed at the bottom is bonded at the point where the adhesive is applied, the side is bonded by the adhesive filled in the joint portion of the upper layer of the composite rubber asphalt sheet made of urethane material ( 3) and; A composite aluminum tape 5 bonded to the adhesive upper portion filled with the joint portion and overlapping a portion of the upper surface of the neighboring composite rubber asphalt sheet; A urethane coating material 6 applied to the composite rubber asphalt sheet and the composite aluminum tape upper surface; The top coating material 8 is applied to the urethane coating film material 6; laminated configuration.

Description of each layer stacked as described above is the same as described above, and redundant description is omitted.

In addition, since the exposure construction method is the same as described above except for the description of some changed parts, redundant description is omitted.

The construction sequence of the present invention having the structure as described above is as follows. The remaining description is replaced by the non-exposure description described above.
