The present invention relates to a method of manufacturing a composite waterproofing material for waterproofing the roof of the building or the upper part of the parking lot, and a construction method using the same. More specifically, the waterproof construction of the non-exposed method on the roof or the parking lot of the newly constructed building structure Of course, if the waterproof construction on the existing building structure reaches the end of its lifespan or aging, the method of manufacturing a composite waterproof sheet that maximizes the waterproof effect while waterproofing with simple and convenient exposure method and waterproof using the same It is about a construction method.

Conventional methods for waterproofing various concrete structures such as rooftop waterproofing of building structures include asphalt sheet waterproofing, EPT vulcanized rubber sheet waterproofing, urethane coating system waterproofing, cement liquid waterproofing, and penetration waterproofing. Cement liquid waterproofing is effective when waterproofing, but when large structures and spans are cracked, the waterproofing layer is also damaged, causing waterproofing.

Asphalt eight-layer waterproofing method has been carried out for decades, which is a layered construction, the waterproof layer is relatively thick, the waterproof effect is excellent and oily, so the winter work is possible, while the asphalt heating is required and at the same time layered As it is a construction process, the process is complicated, special construction technology is required, labor costs are high, the risk of work is high, the environmental pollution problem is serious, and the change of temperature is susceptible to cracking, and it is difficult to find the joint site and the rainy season Considering the construction period, the air had a long disadvantage.

Molded and vulcanized rubber sheets are made of rubber and are manufactured as a sheet, so they have elasticity, tensile strength and elongation, which are inherent characteristics of rubber, and are excellent for impact prevention and have excellent physical properties such as chemical resistance, weather resistance, and aging resistance. Very good as a non-exposure waterproofing material. However, the construction of the connecting portion connecting the sheet and the sheet is difficult, and there are many cases of incomplete adhesion of the connecting portion, resulting in loss of waterproof function due to leakage of the connecting portion.

Rubberized asphalt sheet also tends to be avoided due to frequent defects caused by poor connection of the sheet waterproofing agent. Especially, when it is used for exposure, it is vulnerable to solar heat and ultraviolet rays and thus loses waterproof function due to premature deterioration. It is impossible to apply it as a waterproofing agent for exposure because there is a closed end.

As a method of eliminating the defects of the sheet waterproofing agent, an exposure coating waterproofing agent which is applied by applying a urethane coating waterproofing agent or an inorganic coating waterproofing agent of a water-soluble acrylic material is used. However, the exposure coating waterproofing agent also has adhesiveness with the base concrete. Although there is an advantage that the flat waterproof layer is formed without the three, and the beautiful appearance after the construction, the coating film waterproofing material is difficult to construct and it takes a lot of construction period by constructing it repeatedly several times to form a constant waterproof layer. Yet it was difficult to form a constant thickness waterproof layer.

In addition, after applying urethane coating waterproofing agent and inorganic coating waterproofing agent, which are exposed waterproofing agent, on the roof of building, it is aged and deteriorated by solar heat and ultraviolet rays in 3 ~ 4 years, The waterproof function is lost and must be rebuilt. To re-install with a new urethane or inorganic film waterproofing agent, the existing waterproofing layer must be rolled out and rebuilt, so that the cost of rebuilding is doubled. As the waterproof construction should be repeated periodically every 4 years, there is an enormous cost burden as well as a cumbersome closure that needs to be repeated and repeated.

In addition, in the case of waterproofing the roof of a building by using a conventional sheet waterproofing method, it is common to construct nuclear power plants, large-scale leisure facilities, etc. in recent years, and the floor area of the roof of such a large-scale building is enlarged to a long span. In many cases, when the sheet waterproofing is applied by the exposure method where the floor area of the roof is magnified, when the storm or the strong wind blows, the sheet waterproofing is torn and damaged by the strong wind. It is a situation that a big problem arises in waterproof construction due to the thin end.

When primer is applied in concrete with moisture content of 7 ~ 8% or more, it is only applied on concrete surface, and there is no penetrating power to the parent concrete layer, so when moisture contained in concrete evaporates due to solar heat, When the water is lifted up and the watertight layer is damaged and water penetrates, the water moves under the watertight layer and the water counts to the weak part of the concrete, which makes it difficult to identify the cause of the waterproofing and thus it is difficult to repair the waterproofing defect.

Therefore, in the case of waterproofing the roof of the concrete, it is practically impossible to completely adhere the waterproof sheet onto the concrete by the torch method or the self-adhesive sheet bonding method. Because of this, when the air and moisture existing between the concrete surface and the waterproof sheet are exposed to sunlight, the air therebetween expands to cause bubbles and the waterproof layer (sheet) is separated from the concrete structure. If there is a situation that is bound to be an overall problem.

The present invention has been devised to solve the problems of the conventional waterproofing material and the waterproofing method using the same, and to improve the weakness of the conventional waterproofing method, even if the water content of the base concrete is high or the surface rough, easy and convenient The present invention provides a manufacturing method of a composite waterproof sheet and a waterproof construction method using the same to obtain the effect of perfect waterproof construction and to maintain the waterproof function continuously.

An object of the present invention is to form a composite in which a non-tacky natural fiber sheet or synthetic fiber sheet is attached to both the lower and upper sides of the tackified unvulcanized rubber sheet or tackified rubberized asphalt sheet. It provides a method of manufacturing a composite waterproof sheet, the insulation method of floating the composite waterproof sheet on the base concrete, without the front surface installation or partial attachment of the composite waterproof sheet of the present invention to the entire area of the base concrete ( 부착), but the composite waterproof sheet is applied to the entire area of the base concrete without bending, so that the waterproof construction is applied horizontally and then the liquid paint on the upper layer. Top coating of urethane, epoxy, and methacryl is applied, and the appearance is flat and beautiful and clean. To provide an innovative composite waterproof sheet manufacturing method and a waterproof construction method using the same to maintain a perfect waterproof function.

Another feature of the present invention is the construction of the base concrete and the bottom surface of the entire waterproof layer by the construction of the insulation method, as opposed to the installation of a plurality of debases at intervals of 2-3m as in the conventional case 2-debase at the corner of the construction area Even if only a few of them are installed, the decontamination effect is sufficiently obtained when the moisture contained in the base concrete evaporates, as well as a very small quantity of debase is exposed and the appearance of the waterproof construction is beautiful and clean. In addition, by connecting the composite waterproof sheet and the ends of the waterproof sheet horizontally and flatly on the base concrete, attach the nails to the ends where the waterproof sheet is connected at regular intervals, and then attach them. In addition to reinforcing the construction of one of the joints, in the case of a storm accompanied by strong winds, a very strong wind prevents the waterproofing layer from being damaged or torn off.

Another feature of the present invention is to integrally roll the natural fiber sheet and synthetic fiber sheet having no adhesiveness at the bottom and the upper part of the waterproof layer composed of the unvulcanized rubber sheet in the tackiness state and the tackified rubberized asphalt sheet. By attaching and manufacturing, the fiber sheet attached to the lower layer can be waterproofed without regard to the rough surface of the base concrete, and the natural and synthetic fiber sheets are also attached to the upper layer, and the top coat is coated with a waterproof coating material. In addition, it has a role of protecting the waterproof layer from ultraviolet rays and improves durability.

According to a feature according to the present invention for achieving the above object, the present invention has no adhesiveness at the bottom and top of the tackified unvulcanized rubber (non-vulcanized rubber) dough sheet or tackified rubberized asphalt dough sheet By rolling and attaching a fiber layer made of a natural or synthetic fiber sheet, a composite type composed of a fiber layer having no adhesiveness at the bottom and the top, using an unvulcanized rubber sheet or an asphalt sheet having a stickiness as an intermediate medium. It provides a method for producing a waterproofing agent.

In addition, another feature of the present invention is the unvulcanized rubber sheet or rubberized asphalt in the case of the lower side of the tackified unvulcanized rubber dough sheet and the tackified rubberized asphalt dough sheet while preparing the composite waterproofing agent Natural fiber sheet and synthetic fiber sheet are attached with the same width as the width of the sheet, and the natural fiber sheet and synthetic fiber sheet attached to the upper part are 10 cm smaller than the width of unvulcanized rubber sheet or rubberized asphalt sheet. And it is attached to the synthetic fiber sheet, each of the ends of the unvulcanized rubber sheet or rubberized asphalt sheet is characterized in that it is attached to the inner side 5cm.

In more detail, the composite waterproof sheet of the present invention, the lower side of the unvulcanized rubber sheet and rubberized asphalt sheet in the same size and overlapping natural fiber and synthetic fiber sheet is attached to the upper side unvulcanized rubber sheet and rubberized The composite waterproofing agent is manufactured in the form of attached natural fibers and synthetic fibers in small forms each 5cm at both ends of the asphalt sheet.

In the case of the conventional waterproof sheet, the waterproof sheet is attached to the base concrete by front attachment or partial attachment, and when connecting the waterproof sheet and the waterproof sheet by overlapping the ends of the waterproof sheet by 10 cm, the waterproof material is adhesive. (Adhesiveness) can be used for waterproof construction to connect seamlessly, the conventional sheet waterproofing agent was never produced by attaching a material with no adhesive at the top and the bottom of the adhesive waterproof sheet, but the present invention is an adhesive unvulcanized rubber It is manufactured by attaching a natural adhesive sheet and a synthetic fiber sheet having no adhesiveness to the lower and upper portions corresponding to both sides of the sheet and the adhesive rubberized asphalt sheet, and attaching the non-adhesive fiber sheet to the lower and upper portions of the adhesive waterproof sheet. To provide a manufacturing method completely different from that of a conventional waterproof sheet. It is.

The composite waterproofing agent of the present invention will be described in detail later, even if the concrete surface or concrete floor surface with moisture or moisture on the surface can be installed, the waterproof layer previously waterproofed on the building roof is damaged and the waterproof function is lost. When the water is counted, it is possible to remove the damaged and excited parts without removing the existing waterproof layer completely, and to construct a new waterproof layer. By constructing, the connection area is more firmly attached, and the construction effect is obtained, and even when a strong wind blows due to typhoons, the waterproof layer is torn or damaged, so that it does not fly in the wind and shows a continuous waterproof effect.

The present invention can be waterproof for non-exposure applications or waterproof applications for exposure purposes.

In the case of waterproofing for exposure purposes, the top of the thick natural fiber sheet and synthetic fiber sheet attached to the upper side is coated with liquid paint, urethane, epoxy, methacryl-based coating waterproofing agent with a top coating to make the appearance beautiful and clean. In addition, the thick fiber sheet and the top coating to protect the waterproof layer from the ultraviolet rays of the sun and the effect is greatly improved.

For example, the embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be construed as being limited by the embodiments described below. This embodiment is provided to more completely explain the present invention to those skilled in the art. Accordingly, the shape of the elements in the drawings and the like are exaggerated to emphasize a more clear description.

Exemplary embodiments of the present invention will be described in detail with reference to FIGS. 1 to 4F. In addition, in the drawings, the same reference numerals are denoted together for components that perform the same function.

The basic intention of the present invention is to be installed in a concrete structure with a rough bottom surface, the sheet and the connection portion of the sheet is flat and solid, the method of manufacturing a composite waterproof material and the method of construction less deformation due to temperature changes after construction To provide. To this end, the present invention is manufactured by attaching a non-adhesive material to both sides of the waterproof sheet, and the connection portion of the composite waterproof sheets in one-piece using a band made of a non-adhesive sheet and a sealing agent of the rubber base of the porridge state It is characterized by the fact that the top coating is applied on top of it.

1 is a cross-sectional view showing an exposed composite waterproof structure constructed using the composite waterproof sheet of the present invention. 2A to 2F are diagrams showing the construction method of the composite waterproof sheet shown in FIG. 1 step by step.

The present invention is a very useful and suitable construction method for the structure (base concrete) to remove the existing waterproof layer and reconstruction. In other words, even if the existing damaged waterproof layer is cleanly removed, the conventional concrete surface is very irregular and rough so that the waterproof sheet cannot be completely attached to the ground concrete surface, and the ground concrete is excited by the space between the waterproof sheet and the ground concrete surface. As the moisture generated from the surface is released, the waterproof sheet may be inflated. However, since the present invention is constructed in a state where the surface of the base concrete 10 and the waterproof sheet 120 are separated from each other, construction of the base concrete can be performed even if the base concrete is somewhat rough, and the swelling phenomenon of the waterproof sheet due to moisture and gas generated in concrete is prevented. Without, has a special effect that can be easily discharged to the outside through the de-base (apparatus made to escape air).

Therefore, the construction method of the composite waterproof sheet of the present invention is sufficient degassing when the moisture contained in the ground concrete evaporates even if only a few de-base is installed in the corner of the construction area without installing the de-base at regular intervals Of course, a very small quantity of de-base is installed, so that the waterproof appearance is beautiful and clean.

1 to 2F, when looking at the construction cross section of the composite waterproof sheet according to the present invention, the non-adhesive fiber sheet 110, waterproof sheet 120, non-adhesive fiber sheet 130 from the surface of the concrete 10 And it has a composite waterproof structure consisting of a coating film waterproof layer (top coating, 170). In the exposed composite waterproof structure of the present invention, a space (a) through which the non-adhesive fiber sheet flows between the waterproof sheet 120 and the base concrete 10 surface is provided, and the waterproof sheet 120 is provided. ) The non-adhesive fiber sheet 130 to protect the waterproof sheet 120 from ultraviolet rays and sunlight is located on the top. On the non-adhesive fiber sheet 130 exposed on the top, a liquid coating waterproofing agent (enamel paint, etc.) is applied by a top coating, so that the coating waterproofing agent is absorbed by the upper non-adhesive fiber sheet 130 while maintaining durability of the non-adhesive fiber sheet 130. By improving the coating waterproof layer 170 of a beautiful color while improving, it is possible to have a clean and nice waterproof construction.

Here, the non-adhesive fiber sheet 110 and the waterproof sheet 120 and the non-adhesive fiber sheet 130 will be made of one composite waterproof sheet 100. The composite waterproof sheet 100 is a non-adhesive fiber sheet (110,130) is bonded to both sides of the waterproof sheet 120 by the non-adhesive fiber sheet (110,130) on both sides of the shrinkage and expansion of the waterproof sheet 120 according to the temperature change Because it catches, it is prevented from bending to one side. If the non-adhesive fiber sheet is attached only to one surface of the waterproof sheet, a phenomenon in which the non-adhesive fiber sheet is bent to one side due to shrinkage and expansion of the waterproof sheet according to temperature change will occur. For example, when the temperature increases, the adhesive sheet is stretched and the non-adhesive fiber sheet is bent inward. On the contrary, when the temperature decreases, the adhesive sheet is shrinking and the non-adhesive sheet is not bent. You lose. However, in the present invention, such a problem does not occur, and the non-adhesive natural and synthetic fiber sheet 130 attached to the upper surface of the waterproof sheet serves as a barrier to protect the waterproof sheet 120 from strong sunlight and ultraviolet rays. Therefore, it is possible to prevent deterioration of physical properties of the composite waterproof sheet and to improve durability.

As shown in Figure 1, the composite waterproof sheet structure according to the present invention has a structural feature that the connection portion of the composite waterproof sheet 100 is very firmly bonded. In other words, each of the rubber sheet in the state of porridge is laid out to overlap the natural fiber sheet or synthetic fiber sheet band (hereinafter referred to as fiber sheet band; 140) of a certain width on the bottom of the connection portion of the composite waterproof sheet 100, respectively; The sealing agent 150 is applied to the sealing material of the rubber main material is impregnated in the fiber sheet band 140 to exhibit an adhesive force and has a structure strongly bonded integrally with the fiber sheet band and the composite waterproof sheet 100 at the bottom. .

As such, the exposed composite waterproof structure of the present invention is integrally formed by the fiber sheet bands 140 impregnated with the sealing agent 150 of the rubber material at the top and bottom (upper and lower) of the connection portion of the composite waterproof sheet 100. As a result of the flat joining, it has a strong bonding structure, and the adhesive unvulcanized rubber sheet and the adhesive rubberized asphalt sheet, which are intermediate parts of the composite waterproof sheets, are naturally coated with a rubber-based sealing agent applied on the upper part of the fiber band attached to the bottom. Buried to bond the sheet and the connection of the sheet integrally and strongly.

 In addition, by fixing the nail 160 to the edge portion where the composite waterproof sheet and the sheet is flatly connected at regular intervals, it is possible to prevent the waterproof layer from being blown or damaged by strong wind or the like.

The composite waterproof sheet 100 used here is a non-adhesive fiber sheet (mining sheet, nylon sheet, long fiber nonwoven fabric) on both sides of the adhesive waterproof sheet 120 made of a sticky unvulcanized rubber dough sheet or a sticky rubberized asphalt dough sheet. It is manufactured by attaching any one of the woven sheet, the tire coated sheet, the sheet made of natural fiber, and the sheet made of synthetic fiber) (110,130). Here, the production of the adhesive unvulcanized rubber dough sheet or adhesive rubberized asphalt dough sheet used as a waterproof sheet of the composite waterproof sheet 100 is as follows.
