However, when the waterproofing sheet is used for waterproofing as described above, water leakage may occur at the overlapping portion of the waterproof sheet, and cracks or gaps may occur in the waterproof sheet due to the change in tensile strength of the waterproof sheet, There is a problem that it is difficult to find and repair a defective part when leakage phenomenon occurs.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

FIG. 1 is a side cross-sectional view showing a conventional concrete outer heat insulating structure, and FIG. 2 is a side sectional view showing an outer heat insulating and waterproof composite structure using the hybrid concrete waterproofing material of the present invention.

First, as shown in FIG. 1, a conventional concrete outer heat insulating structure has a structure in which a heat insulating material is formed on the outer surface of the concrete wall and a masonry wall is formed on the outer surface of the heat insulating material. There is a problem that the effect of insulation by a single heat insulator is insufficient.

Particularly, in the case of the conventional concrete outer heat insulating structure, a joint is generated for each joint of the heat insulating material (styrofoam), and the fixing pin and the fastener are inserted into the structural body for fixing, thereby causing damage to the structural body. There is a problem that the heat loss rate is very high due to the air gap at the joint portion and the path of the draft is generated.

In addition, since the durability of the insulation material (styrofoam) is low, the deterioration, shrinkage and material separation progress as time goes by, and the existing structure and the insulation layer lose the function of the present insulation. Stability is very low, and it is vulnerable to external shocks such as earthquakes. When there is a strong impact, material separation is likely to occur.

In addition, the insulation material (Styrofoam) is not only fire retardant like the Jecheon fire but also promotes the diffusion of fire. It not only increases the risk of fire but also does not become waterproof. In particular, in the case of a masonry wall, there is a problem in that the bond and the adhesive which are attached to the masonry are separated and become a path of the draft, and the durability and stability are deteriorated as time goes by.

In order to solve such a problem, referring to FIG. 2, the composite heat insulating, waterproofing and reinforcing composite structure using the hybrid concrete waterproofing material and the heat insulating and reinforcing material according to the present invention will be described. Methacrylate and butadiene rubber latex is included in the masonry wall or outer wall surface 103 of the concrete outer layer structure in which the heat insulating material 102 is formed and the masonry wall or the outer wall body 103 is formed on the outer surface of the heat insulating material. An organic / inorganic hybrid waterproofing material layer 104 formed by applying an organic / inorganic hybrid waterproofing material composition obtained by mixing a cement powder and a porous feldspar particles to an acrylic copolymer liquid resin prepared by copolymerizing A first mortar layer 105 formed on the outer surface of the organic / inorganic hybrid waterproofing material layer 104 by applying mortar composed of cement powder, silica sand and porous feldspar particles; And a finish material (106) adhered to the outer surface of the first mortar layer (105).

Here, the acrylic copolymer liquid resin is prepared by copolymerizing a composition containing acrylate, methacrylate and butadiene rubber latex as an organic liquid resin excellent in crack resistance, wherein acrylate, methacrylate and butadiene rubber latex are copolymerized , So that not only crack resistance but also adhesion and elasticity of butadiene rubber latex can be added to exhibit excellent waterproof durability.

At this time, the organic / inorganic hybrid resin composition of the present invention is characterized in that -COOH groups of acrylate and methacrylate contained in the acrylic copolymer liquid resin are cations and cations including sodium ions, calcium ions, and magnesium ions present in the cement powder and porous feldspar particles, Ionic bond to thereby manifest the adhesion strength and tensile strength of the organic / inorganic hybrid waterproofing material layer, and the butadiene rubber latex contained in the acrylic copolymer liquid resin exhibits the adhesion and elasticity of the organic / inorganic hybrid waterproofing material layer.

On the other hand, in the present invention, feldspar is used as a heat insulating material and exhibits an adiabatic effect. Feldspar is the most common natural substance among the substances constituting the crust, and it is used in the production of glass, paint and the like as industrial minerals. The mineral structure of these feldspars is primarily related to the arrangement and disposition of Al and Si, the twinning, the coarsening, and their complex structure (Parsons, 1994; Smith & Brown, 1988; Deer et al., 2001) And microstructure due to alteration.

Particularly, in the weathering process, fine pores are characteristically developed on the surface of the feldspar. Due to the porous structure of the feldspar, the specific surface area increases, the volume characteristics decrease, and the surface characteristics increase. As a result, the electrical / (Park & Lee, 2000) have been reported.

In the present invention, it is a key feature of the present invention to utilize the minute voids of the porous feldspar to exert an adiabatic effect.

That is, the organic-inorganic hybrid waterproofing material layer 104 of the present invention is an organic-inorganic hybrid material obtained by mixing cement powder and porous feldspar particles with an acrylic copolymer liquid resin prepared by copolymerizing a composition comprising acrylate, methacrylate and butadiene rubber latex The waterproofing composition is applied and laminated integrally.

At this time, the porous feldspar particles preferably have a particle size of 40 mu m to 1 mm in the heat insulating effect.

A reinforcing fiber layer 107 reinforced with reinforcing fibers selected from nonwoven fabric, carbon fiber, glass fiber, aramid fiber, polyester fiber and metal fiber is further interposed between the first mortar layer 105 and the finishing material 106 So that the tensile strength of the concrete structure can be reinforced.

The second mortar layer 108 is further sandwiched between the reinforcing fiber layer 107 and the finishing material 106 by sandwiching a mortar composed of cement powder, silica sand and porous feldspar particles to waterproof and reinforce it The heat insulating effect can be further improved.

In addition, in the present invention, the porous feldspar particles contained in the organic-inorganic hybrid waterproofing material layer, the first mortar layer and the second mortar layer may have porosity as the heat insulating material in the organic-inorganic hybrid waterproofing material layer, the first mortar layer and the second mortar layer And the adiabatic effect is manifested as a characteristic effect of the present invention.

On the other hand, the composite heat insulating, waterproofing and reinforcing composite structure using the hybrid concrete waterproofing material of the present invention and the insulating and reinforcing material of the present invention is characterized in that a heat insulating material is formed on the outer surface of the concrete wall and a concrete outer surface An organic / inorganic hybrid waterproofing material composition comprising a cement powder and a porous feldspar particle mixed with an acrylic copolymer liquid resin prepared by copolymerizing a composition comprising acrylate, methacrylate and butadiene rubber latex on the surface of the masonry wall or outer wall of the heat insulating structure To form an organic-inorganic hybrid waterproofing material layer; Forming a first mortar layer by applying a mortar composed of cement powder, silica sand, and porous feldspar particles to an outer surface of the organic / inorganic hybrid waterproofing material layer; And attaching a finish material to the outer surface of the first mortar layer.

A reinforcing fiber layer reinforced with reinforcing fibers selected from nonwoven fabric, carbon fiber, glass fiber, aramid fiber, polyester fiber and metal fiber may be further formed between the first mortar layer and the finishing material. A mortar composed of cement powder, silica sand and porous feldspar particles may be sandwiched between the finishing materials to form a second mortar layer.

The concrete used in the present invention can be applied to concrete or civil engineering structures such as an interior, roof, roof, basement, underground parking lot, swimming pool, bridge, road, oil storage tank, highway, As a surface, the present invention can have an outer heat insulating, waterproof and reinforced composite structure.

In addition, since the present invention is integrally bonded to the concrete structure with the reinforcing fiber, the tensile strength is remarkably increased to prevent the concrete from being collapsed even during an earthquake or the like, which is an excellent effect applicable to seismic strengthening and seismic design .

That is, although the masonry wall and the outer wall are formed as separate walls, the masonry wall and the outer wall are very weak against earthquake, vibration, and impact, but the present invention is characterized in that carbon fiber, glass fiber, aramid fiber, The reinforcing fiber reinforced with the reinforcing fibers selected from the reinforcing fibers further enhances the restraining force of the coarse wall by covering the entire structure, and forms a continuous wall instead of the partition wall, thereby being able to withstand earthquake, vibration and impact .

The foregoing description is merely illustrative of the technical idea of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention. Therefore, it should be understood that the present invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
