The present invention relates to a waterproof sheet for waterproofing the exposed portion of the concrete structure, such as the roof of the building or parking lot and underground exterior walls.

In general, the waterproof method can be divided into waterproof film and waterproof sheet, the waterproof film has the advantage of making a continuous waterproof layer, but there is a weak point in making a certain thickness of the waterproof layer. On the contrary, the sheet waterproof can make a waterproof layer having a certain thickness and a performance of a physically strong waterproof layer, but there is a big weak point in the bonding of the connection portion between the sheet. Due to the problems described above, the composite waterproof is to supplement the weakness of the sheet by preventing the leakage by connecting the physical performance of the sheet and the connection between the sheet and the sheet with a coating film. Representative of the complementary method is the I method, and the nonwoven fabric type sheet is bonded in the form of I type using urethane. The bonding order of the I method is to fold the sheet laid in advance and make a coating layer at the bottom, and then cure after folding. After the reinforcing agent is attached to the top and the coating film is applied again. This method has a high labor cost, and the nonwoven sheet has a problem in that the non-woven sheet is rolled up due to different expansion coefficients of the material and exceeds the amount of the coating agent prescribed when the coating agent is applied thereon.

In addition, the asphalt-based sheet has a problem that melted in the urethane-based coating film has a non-woven fabric to protect the sheet, but the end of the sheet is exposed to the urethane-based coating film, there is a problem that damage the sheet.

As another example of the composite waterproofing, after the coating agent is applied, the extended nonwoven fabric is bonded, and then the coating agent is applied and the sheet is bonded. Then, there is a method of adhering the reinforcing agent and applying the coating agent thereon. The above method has to go through six steps to join, and the method I can also achieve the I-shaped joining structure through six steps as well, and there is a problem in that the material cost also increases because a reinforcement must be used.

In addition, the biggest problem of the conventional sheet method is that there is a difficulty in the generation and repair of defects. 1 is a conventional sheet method using a conventional sheet. As shown in FIG. 1 (a), the sheet 50 and the sheet 50 'are overlapped to each other by about 100 mm, so that the material is consumed about 10% more, as shown in FIG. 1 (b). When a force is applied to the connecting portion 60 of the sheets 50 and 50 'or when the processing of the connecting portion 60 is immature, the connecting portion 60 of the sheet is lifted or broken and water 70 flows in. Once the water 70 is introduced, even a properly constructed part appears to be lifted up and the water 70 moves around the sheet bottom. And the non-woven fabric or PP fabric used as the center of the sheet 500 is made of fibrous fiber, which usually shows a high elongation and tensile strength, but if a strong force is applied in one direction, the sheet continues to be damaged as if the fabric is torn once. If a defect occurs due to the water 70 is rotated there is a problem that the repair of the defect is almost impossible.

The present invention was devised to solve the above problems, and is provided with a mesh-type glass island sheet, so that the reinforcing agent is not required when connected to the double junction structure in the sheet-to-sheet connection structure, thereby reducing the running cost. It can be, and has a double connection structure is to provide a waterproof sheet that can simplify the work and reduce labor costs.

In addition, it is possible to form a stable waterproof layer by removing the phenomena of damage between the waterproofing agents using asphalt-based and water-soluble coating film, and to provide a waterproof sheet that can maximize the waterproof performance by forming a continuous waterproof layer of the same material. The purpose.

It is also an object of the present invention to provide a waterproof sheet capable of localizing a defect repair site by providing a double junction structure to prevent an overall leak when leaking.

In order to achieve the above object, the mesh-type fiberglass sheet of the present invention is a waterproof sheet having a waterproof function, comprising a polyester nonwoven fabric as a center, and coated with an SBS modified asphalt after impregnating a predetermined thickness; And an upper layer formed integrally with the upper surface of the center layer by a mesh-like glass fiber material and including a wing portion formed to extend 50 to 100 mm on both sides of the waterproof sheet; And a release material layer attached to the lower surface of the center layer.

Here, the upper layer is characterized in that the silica sand attached to the upper surface of the center layer.

Hereinafter, the present invention mesh-type fiberglass sheet will be described in detail with reference to the accompanying drawings.

2 is a view for explaining the mesh-type glass fiber sheet (1) according to the present invention. As shown in the figure, the mesh-type fiberglass sheet 1 is a core layer 10 made by completely impregnating the SBS improved asphalt 110 on a polyester nonwoven fabric, which is a central agent 100, and then coating the sheet with a predetermined thickness. ) And the upper layer 20 of the mesh-shaped glass fiber 210 formed integrally on the upper surface of the center layer 10 and the release material layer 30 attached to the lower surface of the center layer 10. Is done.

Here, the upper layer 20 has a wing portion 200 extending about 50 to 100 mm on both sides of the sheet 1, and is characterized in that the mesh-like glass fiber 210 and the silica sand 200 are attached together.

First, the silica sand 220 to be attached together with the mesh-like glass fiber 210 when the coating agent is applied to the upper surface of the sheet 1 during the waterproof construction work, increases the adhesive force and serves as a ring to help impregnation. In addition, the waterproof construction work is to step on the upper surface of the seat as the worker moves. The upper surface of the seat is made of asphalt so as to prevent the sticking to the shoes to provide convenience for the worker to work do.

In addition, the wing portion 200 of the upper layer 20, which is the main part of the present invention, has a shape of a mesh made of glass fiber 210, and the feature of the glass fiber 210 is that there is no expansion rate against heat and the sheet due to heat It prevents deformation and prevents damage to the sheet due to its high tensile strength. Since it is a mesh structure, it has a characteristic that it can be dispersed with a constant force when subjected to strong force. In addition, since the wing portion 200 has a net structure, the coating material can directly contact the concrete matrix, so that the coating material is spread and immediately impregnated under the glass fiber, thereby simultaneously producing the same effect as bonding the sheet to the upper and lower doubles. The waterproof construction process is reduced, and there is no consumption of subsidiary materials such as reinforcing agents, thereby reducing the material and labor costs.

In addition, the release material layer 30 is attached to the lower surface of the center layer 10, the release material layer according to the characteristics of the structure to be constructed and the method of construction, such as hot air, cold air, and various construction methods such as non-exposed type, exposed type It is preferable that 30 attaches any one of a self-supporting type, a torch type, a silica sand (more) type, and a nonwoven type.

The mesh-type glass fiber sheet (1) has a central agent has all the physical properties of the greatest advantage of the conventional waterproof sheet and is designed in accordance with the KS standard, unlike other sheets used in the conventional composite waterproofing method.

The mesh-type glass fiber sheet (1) is a non-woven fabric of the upper and lower parts of the normal waterproof sheet using a non-woven fabric of the glass fiber 210 and the central agent 100 having no thermal expansion rate, the thermal expansion rate of the sheet The shape is inaccurate and prevents the sheet from drying out due to deformation or heat of the sheet.

In addition, since the mesh-shaped glass fiber 210 is formed integrally on the upper portion of the sheet, the tensile strength is higher than that of the polyester nonwoven fabric of the core 100, and since it is a net structure, it is dispersed with a constant force when a strong force is applied to the core 100 and Double pressure is applied to prevent sheet damage.
