Description

[0001] The present invention relates to a water-proofing system and a water-proofing type construction method using the same,

The present invention relates to an oil / inorganic multi-layer waterproofing system capable of shortening the safety, construction convenience, and construction time of a worker at the time of construction, and an organic / inorganic composite multi-layer waterproofing construction method using the same.

Generally, the waterproof layer functions to protect the bottom plate from infiltration water, and plays a role of ensuring waterproofness and adhesion, forming structural identity, and securing durability. The penetration of water promotes fatigue failure in concrete decks and corrosion of reinforcing bars and steels, thereby lowering durability. Therefore, the waterproof layer plays an important role as a layer for improving the durability of the package and the bottom plate by preventing water penetration. The importance of the waterproofing layer is increasing due to the fact that the waterproofing layer has not been recognized since its importance was not recognized at the early stage of application, but recently various waterproofing materials and methods have been developed and also affected the mechanical relationship between the bottom plate protection and the asphalt layer .

The waterproofing agent is a mixture of two or more raw materials such as asphalt, synthetic rubber, synthetic resin, fiber, mineral and volatile solvent. Generally, the waterproof layer can be classified into a permeation system, a sheet system, a coating system, and a packaging system.

First, the penetrating system waterproofing agent penetrates the micro pores of the concrete deck surface to penetrate the waterproofing agent and form the primary water film, which is bonded and diffused by the continuous chemical action with the silicon (Si) component in the concrete, And protect concrete from damage caused by moisture and salt. It has been used mainly in the past, but its waterproof performance is less than that of coating system, sheet system, and packing system waterproofing agent, and it is hardly applied at present.

Second, the sheet type waterproofing agent has an advantage of excellent waterproof effect and good adhesion to the pavement layer. In order to prevent breakage by construction load, the surface is treated with glass fiber and it can be applied irrespective of the surface condition of the bottom plate. However, there is a disadvantage that maintenance work is difficult and adhesion to the bottom plate is insufficient. However, recently, new methods of reinforcing glass fiber in sheet systems have been supplemented with disadvantages of sheet type waterproofing agents to improve strength and adhesion.

Third, packaged waterproofing agents are generally used as goos asphalt, and in the UK and Europe, mastic asphalt is also used. It is mainly applied to steel decking, and it has an advantage of obtaining effective waterproofing on the joint part of the bottom plate.

Fourth, the coating system waterproofing agent has an advantage that it can be easily applied at the time of repair work, and it is excellent in waterproof effect because of its excellent adhesion with the bottom plate. However, there is a disadvantage that the adhesive strength to the packing layer is insufficient. In order to solve these problems, silica sand is sprayed on the waterproof layer to improve the adhesion strength with the asphalt layer. Coating systems can be classified into synthetic rubber coating systems, asphalt coating systems and epoxy resin coating systems. Among them, epoxy resin coating waterproofing agent is excellent in adhesion to concrete, but there is a problem that an asphalt mixture should be installed within the resin time of the resin in order to ensure adhesion with the asphalt pavement.

In connection with the waterproofing method, conventional waterproofing methods include a complete waterproofing method, a rubber-based film waterproofing method, an asphalt sheet waterproofing method, and a rubberized asphalt method.

The finished waterproofing method has a problem that the waterproofing function becomes ineffective when it has been used for a long time or cracks. The rubberized asphalt method is widely used as a non-exposed waterproofing material, but has a problem of weathering due to aging phenomenon. The waterproofing methods were generally excellent in waterproofing performance, but the peeling phenomenon occurred because the concrete layer, the waterproof layer and the ascon layer were not integrated and there was a problem in adhesion. In order to solve these problems, adhesion of silica sand or aggregate to unevenness was made to improve adhesion with ascon. However, as the waterproof layer is slackened due to the rise in temperature in summer, the silica sand that fixes the ascon layer and the waterproof layer is separated from the ascon layer, There is a problem that cracks and irregularities are generated on the bottom of the ascon.

Korean Patent No. 10-0883743 (Mar. 02, 2009), "Bridging and waterproofing method using brick or concrete multi-layer waterproofing system of a concrete structure" has been proposed in order to solve the above problems.

The above patent discloses a cross-linked waterproofing agent composition having excellent adhesiveness to unite concrete, a waterproof layer and an ascon layer so as to suppress the occurrence of cracks, and to solve the problem that unevenness is generated by being peeled off.

However, the above patent has a problem in that all the materials are not made water-soluble and workability is remarkably lowered.

Also, since the construction process is very complicated, there is a problem that the construction time becomes long.

In order to solve the above-mentioned problems, the organic / inorganic composite multi-layer waterproofing system of the present invention and the organic / inorganic multi-layer waterproofing construction method using the same have improved the work by watering all the materials, The purpose is to protect the safety of the constructor.

Another object of the present invention is to provide a water and inorganic composite multi-layer waterproofing system which does not cause an increase in tensile strength, improvement in adhesion, and lifting due to gas or moisture by applying a sheet composed of through holes, a degassing line, And to provide a multi-layer waterproofing method using organic and inorganic materials.

The present invention relates to a waterproof, high-elastic tar waterproofing agent, a water-based high-elasticity tar waterproofing agent and an aqueous high-elasticity acrylic waterproofing agent which are not used at all, Water resistance can be obtained.

In addition, since the primer, the water-based high-elasticity tar waterproofing agent, and the water-based high-elasticity acrylic waterproofing agent are water-soluble, workability can be improved.

The connecting sheet is formed so as not to cause deformation of the through holes formed at regular intervals, and the sheet having the degassing line in a certain section is used to form a close adhesion between the primer and the water-based high-elastic tar water repellent agent, So that the tensile strength can be improved.

Further, the weather resistance and durability can be improved through the water-based high-elasticity acrylic waterproofing agent which is the top coating agent.

In addition, it is a useful invention for forming an outdoor parking lot on the roof by further forming an anti-slip agent.

Next, barium sulphate (BaSO ₄ ) is a solid substance with a melting point of 1580 ° C and a specific gravity of 4.499, which is almost insoluble in water but has a melting property in concentrated sulfuric acid. It does not discolor when heated or acts on hydrogen sulphide. (Barytes). It is called barium sulphate or barite powder which is ground by spraying. It is suitable as filler for external exposure because of its high chemical resistance and weatherability. It has viscosity and high hiding power. Paper fillers, X-ray contrast agents, fillers for rubber resins, fillers for various paints, etc. In the present invention, extender pigments are used for the stability of the product.

Next, calcium carbonate is a carbonate of calcium and is produced from marble, calcite, mudstone, limestone, chalk, ginkgo stone, clamshells, egg shells and coral. It is used as various kinds of neutralizing agents such as raw materials for cement, raw materials for calcium oxide, iron and building materials

Such calcium carbonate is roughly divided into two types of heavy calcium carbonate and light calcium carbonate depending on the production method.

Heavy calcium carbonate is calcium carbonate produced by crushing and classifying white crystalline coal seats and is called white calcium carbonate because of its high whiteness. The particle size is usually 5 μm or less, and it is used for various industrial fillers, food additives, and medicines.

Light calcium carbonate is a chemically produced calcium carbonate produced by calcining coal ash, which is also referred to as light calcium carbonate. Of the hard calcium carbonate, particularly, the colloidal calcium carbonate having a particle size of about 0.1 to about 0.002 μm is called colloidal calcium carbonate, which is distinguished from a spindle-shaped, columnar-shaped calcium carbonate of 1 μm or more.

The inorganic and organic composite waterproofing agent 40 is soft and serves to protect the water-based high-elasticity tar waterproofing agent 30 and the sheet 20, (30).

In addition, the organic / inorganic composite waterproofing agent 40 acts on the sheet 20 so that a smooth surface can be formed at a portion where the layer itself is not flat, and thus, when applied with a water- As shown in Fig.

In particular, the organic / inorganic composite waterproofing agent 40 can function as a waterproofing agent itself, and the constituent elements function to form a multi-layered waterproof layer so as to improve waterproofness.

Next, the water-based high-elasticity acrylic waterproofing agent 50 comprises 20 to 22% by weight of water, 0.08 to 0.10% by weight of ethylhydroxyethylcellulose, 3.5 to 4.0% by weight of an aqueous pigment, 27 to 30% by weight of calcium carbonate, Styrene copolymer emulsion resin, 2.4 to 2.7 wt% of a plasticizer, 0.1 to 0.12 wt% of a defoamer, 0.15 to 0.2 wt% of a dispersing agent, and 0.05 to 0.08 wt% of a leveling agent.

Further, the degassing line 23 formed on the sheet 20 acts to increase the tensile strength, so that cracking of the concrete structure can be suppressed, and even if cracks are generated, it can be supported. Can be obtained.

Also, since the sheet 20 can not be manufactured to have the same size as the concrete structure, several sheets 20 are used.
