Description

Construction method for insulation and waterproofing {CONSTRUCTION METHOD FOR WATERPROOF AND INSULATION}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction method for constructing a building structure, and more particularly, to a construction method for insulation and waterproofing, wherein the insulating and waterproofing materials are applied to a rooftop of a building structure and the like.

In general building structures, waterproofing is essential to prevent leakage from precipitation and the like, and to prevent cracking of the structure and deterioration of durability. Conventional waterproofing methods include asphalt 3-ply 8-layer waterproofing, urethane coating waterproofing, heated sheet waterproofing, urethane composite waterproofing, asphalt composite waterproofing and the like.

Among these, the asphalt three-ply eight-layer waterproofing is a method that has been applied to the waterproofing part of the molten asphalt such as asphalt felt, asphalt compound, asphalt roofing as the waterproofing method that has been used for the longest time. The asphalt waterproofing is excellent in waterproofing effect and excellent durability and watertightness because the coating layer of the waterproofing layer is relatively thick, but it is required to melt solid asphalt at high temperature, so special construction technology is required and the construction of vertical surface is impossible and sensitive to temperature change. There is a problem that cracks are likely to occur.

The urethane coating waterproofing is a waterproofing method using the remaining film after water or solvent is evaporated after applying the waterproofing agent in the oily liquid form to the surface to be waterproofed. The urethane coating waterproofing is used as a waterproofing agent such as roofing because it is easy to install and free to color, but because of the use of volatile solvent, the risk of fire is high, the necessity of ventilation, etc. is required, depending on the degree of volatilization of the solvent during coating work Bubbles may occur, and there is a problem that they are relatively vulnerable to moisture.

The heated sheet waterproofing is a waterproof method for bonding asphalt and rubber non-woven fabric as a main raw material and the waterproof sheet, which has been made to a certain standard, on the asphalt primer-treated structure. Since the ready-made waterproof sheet is not self-adhesive, a method of melting and attaching a waterproof sheet joint part using a torch lamp or the like is generally used. However, when the waterproof sheet is heated by a torch lamp or the like, carbonization of the waterproof sheet proceeds, thereby shortening the waterproof life, and the film of the carbonized gas and the waterproof sheet is entangled, and thus the adhesive strength of the portion is lowered.

The urethane composite waterproof is a waterproof method using an unexposed waterproof sheet and exposed polyurethane. However, in the urethane composite waterproofing, the waterproof sheet only forms a thickness and has a low contribution to the waterproofing effect. In addition, the exposed polyurethane mainly used in the urethane composite waterproofing is complicated in construction and high incidence of defects, and if the content of thinner used to dilute the urethane is high, it may potentially melt the asphalt, the main raw material of the waterproof sheet. There is a problem that leads to defects such as material separation.

The asphalt composite waterproof is a modified method of waterproofing the asphalt 3-ply 8-layer, using a mixture of the waterproof sheet and the asphalt seal. The asphalt composite waterproofing, inevitably occurs in the step of heating the asphalt seals cause environmental pollution, and in winter, because the heat-treated asphalt seal is easily hardened due to low temperatures, workability is also reduced, and material loss is also remarkable. There is a problem.

On the other hand, in a general building structure, the method of inserting a heat insulating material, such as a styropole, in a wall surface etc. is used for heat insulation. In addition, even when constructing a rooftop floor of a building structure, the insulation is inserted into an outer wall forming the rooftop floor.

However, since the heat insulating material such as the styropole is not inserted into the wall surface or the like normally, the heat insulating function due to the styropole is deteriorated.

In particular, even though the insulation material such as the styropole is vulnerable to moisture, since the styropole is left at the construction site in the construction of the rooftop, when the styropol is inserted into the rooftop and the construction is completed, the styropol is insulated. This situation is not fully exercised.

In addition, since the process of inserting the insulation to the rooftop, etc. is required, the entire process of the building structure may be delayed.

In addition, in the case of the rooftop floor in which the construction is completed with the insulation inserted once or the rooftop construction in which the construction is completed without the insulation being inserted, additional methods for improving the insulation function have not been proposed.

In other words, when the rooftop is completed, the waterproofing treatment may be additionally performed by various methods as described above, but it is difficult to additionally insulate.

The present invention has been proposed to solve the above problems, the cement and a lightweight insulating material that can perform the thermal insulation function, to apply a thermal insulation waterproof mortar mixed by a waterproofing agent that can perform the waterproof function on the surface of the structure It is a technical problem to provide a construction method for heat insulation and waterproofing.

The construction method for heat insulation and waterproofing according to the present invention for achieving the above-described technical problem, the method comprising the steps of: arranging a heat insulating plate having a plurality of holes formed in the form of a grid; And injecting a heat-insulating waterproof mortar mixed with cement and a lightweight heat insulating material capable of performing a heat insulation function into the holes formed in the heat insulating plate to form a heat insulating waterproof mortar layer. It includes.

Another insulation and waterproof construction method according to the present invention for achieving the above technical problem, the thermal insulation waterproof mortar mixed with a cement, a lightweight insulation material that can perform the thermal insulation function, a waterproofing agent that can perform the waterproof function To apply to the surface of the structure to form a heat insulating waterproof mortar layer; And forming a crack preventing layer by stacking a crack preventing material on the surface of the insulating waterproof mortar layer to prevent cracking of the insulating waterproof mortar layer.

According to the present invention, heat insulation and waterproofing of a structure exposed to the outside, such as a rooftop surface, can be made easily.

In addition, according to the present invention, since a lightweight heat insulating material capable of performing a heat insulating function is used, the load on the rooftop floor can be reduced.

In detail, the present invention may be practiced to improve the heat insulation and waterproofing function of the rooftop floor which is already constructed and used, or may be practiced for the manufacture of the rooftop floor under construction.

After the primer layer 10 is dried, the primer layer 10 may be applied to the primer layer 10 once again.

On the other hand, the primer layer 10 may be omitted.

Next, referring to FIG. 3, the heat insulation plate 21 is disposed on the primer layer 10 (S104).

That is, the thermal insulation waterproof mortar layer 20 to be described below is a material containing cement, and after drying, fine cracks or the like may be formed.

However, since the expansion or contraction of the thermal insulation waterproof mortar can be prevented by the lattice-shaped holes formed in the insulation plate 21, the occurrence of minute cracks in the thermal insulation waterproof mortar layer 20 can be prevented. have.

The hole formed in the heat insulating plate 21 may have a rectangular shape as shown in FIG. 3, but may be circular, and may have other shapes.

The heat insulation plate 21 may have a thickness of 5 to 10 mm.

Next, referring to FIG. 4, the thermal insulation waterproof mortar 22 mixed with cement and a waterproof insulation material that can perform a thermal insulation function, and a waterproofing agent that can perform a waterproof function is formed on the thermal insulation plate 21. By injection into the holes, the heat-insulating waterproof mortar layer 20 is formed (S106).

As described above, the thermal insulation waterproof mortar 22 is formed by mixing cement and a lightweight thermal insulation agent by the waterproofing agent.

As described above, the waterproofing agent may be any one of various kinds of waterproofing agents currently used.

The lightweight insulation may be applied to a material that is light and has a thermal insulation function. For example, styropol may be applied as the lightweight heat insulating agent.

When Styropol is used as the lightweight insulation, the weight ratio of cement, lightweight insulation and waterproofing agent may be mixed at 3: 1: 2.

However, the weight ratio may be changed in various ratios. That is, the weight ratio may be variously set in a ratio of 1 to 4: 1 to 2: 1 to 3, and the like.

As shown in FIG. 4, the adiabatic waterproof mortar 22 may be injected into the adiabatic plate 21 by an adiabatic waterproof mortar spraying apparatus 23. The adiabatic waterproof mortar spraying device 23 may be a container containing the adiabatic waterproof mortar 22 or may be a conveying pipe for transferring the adiabatic waterproof mortar 22.

Next, referring to FIG. 5, the heat insulating waterproof mortar 22 is coated on the heat insulating plate 21 and then flattened. Accordingly, the heat insulating waterproof mortar layer 20 is completed (S106).

Is an illustration showing a state where the surface of the substrate is flattened.

After the adiabatic waterproof mortar layer 20 is dried, the adiabatic waterproof mortar layer 20 may be applied to the adiabatic waterproof mortar layer 20 once again.

Next, referring to Figure 6, by applying a waterproof mortar to the heat insulating waterproof mortar layer 20, a waterproof mortar layer 30 is formed (S108).

The waterproof mortar layer 30 performs a waterproof function. To this end, the waterproof mortar layer 30 is formed of waterproof mortar in which sand and cement are mixed by the waterproof agent.

The waterproof mortar may be manufactured by mixing sand and cement with a material, that is, remittal and the waterproofing agent in a weight ratio of 5 to 1.

However, the ratio can be variously changed. For example, the ratio may be set variously in a ratio of 4-6 to 2-3.

The waterproof mortar layer 30 may be formed to a thickness of 7 to 10mm.

That is, the waterproof mortar layer 30 is formed in the heat insulation waterproof mortar layer 20, and may further perform a waterproof function.

Therefore, in some cases, the waterproof mortar layer 30 may be omitted.

Next, FIGS. 7 to 10 show a process of forming a pattern on the surface of the heat-insulating waterproof mortar layer.

That is, by applying the heat-insulating waterproof mortar layer 20 or the waterproof mortar layer 30, the insulating and waterproof construction method according to the present invention may be terminated. In this case, a coating agent for protecting the surface of the insulating waterproof mortar layer 20 or the waterproof mortar layer 30 may be coated on the top of the insulating waterproof mortar layer 20 or the waterproof mortar layer 30. .

However, when the construction is stopped in the state in which the heat-insulating waterproof mortar layer 20 or the waterproof mortar layer 30 is exposed on the roof surface or the like, the appearance may not be good.

Therefore, a pattern may be formed on the heat-insulating waterproof mortar layer 20 or the waterproof mortar layer 30 by various methods.

As a method of forming the pattern, a method of attaching a tile or the like may be applied, or a stencil method may be applied. Hereinafter, a method of forming a pattern by the stencil method will be described.

In order to form a pattern by the stencil method, as shown in Figure 7, the protective mortar to which the pigment for expressing the pattern is applied, the heat-insulating waterproof mortar layer 20 or the waterproof mortar layer 30 ) Is applied to the surface of, to form a protective mortar layer (40) (S110).

The protective mortar layer 40 may be formed by mixing powder and resin in a weight ratio of 3 to 1, but is not limited thereto. That is, the weight ratio of the powder and the resin may be variously set at a ratio of 2 to 4 to 1 to 2.

Here, the powder and the resin may be selected as materials having good adhesion to the pigment. As the resin, an acrylic resin may be used, and various other materials used in the stencil method may be applied.

The powder may also be applied to various materials used in the stencil method.

In particular, the protective mortar layer 40 may be a material described in the registration number 10-0890367.

The protective mortar layer 40 may be formed to a thickness of 1 to 2mm.

That is, the protective mortar layer 40 may be formed of a material having a high adhesive strength so that the tile or the pigment can be attached well.

In addition, the protective mortar layer 40 may perform a function of protecting the thermal insulation waterproof mortar layer 20 or the waterproof mortar layer 30.

Next, referring to FIG. 8, the pattern paper 51 is attached to the surface of the protective mortar layer 40 (S112).

Next, referring to FIG. 9, the pigment 52 is coated on the surface of the protective mortar layer 40 to which the pattern paper 51 is attached using the spraying device 53 (S114).

Since the pattern forming part penetrates through the pattern paper 51, the pigment passes through the penetrating part and is applied to the surface of the protective mortar layer 40.

Therefore, portions corresponding to the patterns are coated with the pigment on the protective mortar layer 40. That is, with the pigment, a pattern having the same shape as that of the pattern formed on the pattern paper 51 is formed on the protective mortar layer 40.

Next, referring to FIG. 10, the pattern 50 is removed from the protective mortar layer 40 so that the pattern 50 is represented on the surface of the protective mortar layer 40 (S116).

Finally, referring to FIG. 11, a coating material is applied to the surface of the pattern 50 to form a coating layer 60 (S118).

In this case, the coating layer 60 is coated on the protective mortar layer 40 exposed between the surface of the pattern 50 and the patterns 50.

By forming the coating layer 60 on the protective mortar layer 40 and the pattern 50, the heat insulating and waterproof layer 70 is formed on the surface of the structure (1).

The coating material may be applied to various kinds of materials for protecting the surface of the cement structure, and the like, in particular, a transparent material may be applied.

That is, according to the construction method for heat insulation and waterproofing according to the present invention as described above, by the simple construction in which the heat-insulating waterproof mortar mixed with a cement and a lightweight heat insulating material by a waterproofing agent is applied to the structure (1), the heat insulating function and waterproof function This can be achieved.

Therefore, since the construction process for insulation and waterproofing can be simplified, the construction period of the structure can be shortened, and also the construction cost can be reduced.

Hereinafter, another embodiment of the construction method for heat insulation and waterproofing according to the present invention (hereinafter referred to as 'second embodiment') will be briefly described. In the following description, the content overlapping with the above description may be simply described or omitted.

Next, a heat-insulating waterproof mortar 22 mixed with cement and a lightweight heat insulating material capable of performing a heat insulating function and a waterproofing agent capable of performing a waterproof function is applied to the surface of the structure 1 to provide a heat insulating waterproof mortar layer. 20 is formed. That is, in the embodiment described with reference to FIGS. 1 to 11 (hereinafter, referred to as 'first embodiment'), the heat insulation waterproof mortar layer 20 is formed on the heat insulation plate 21, but the second embodiment In the primer layer 10, the heat-insulating waterproof mortar layer 20 is directly formed.

Next, a crack preventing material is formed on the surface of the heat insulating waterproof mortar layer 20 to prevent cracking of the heat insulating waterproof mortar layer 20, thereby forming a crack preventing layer.

The crack preventing layer, as performing the same function as the heat insulation plate 21, a thin cloth such as a non-woven fabric may be applied.

Next, a waterproof powder mixed with a waterproofing agent and powder is applied to the surface of the crack preventing layer, thereby forming a waterproof powder layer.

The waterproofing powder performs a waterproofing function and is selected from materials having good adhesion with a pattern to be described below.

Next, a pattern is formed on the waterproof powder layer. The pattern may be applied to the method described with reference to FIGS. 8 to 10 and other various methods.

Finally, a coating material is applied to the surface of the waterproof powder layer formed on the pattern to form a coating layer, thereby forming a heat insulating and waterproofing layer.

In the structure produced by the present invention as described above, water does not penetrate, and the structure is excellent in breathability. Therefore, when constructing a roof or the like using the present invention, the heat insulation and waterproof effect is very excellent.

That is, the structure manufactured by the insulation and waterproof construction method according to the present invention, while preventing the permeation of water, while allowing the air to permeate, it is possible to prevent the rotting phenomenon inside the structure.

In detail, in the related art, waterproofing of a structure was performed using a rubber-based material such as urethane.

However, since rubber-based materials such as urethane are not breathable, a swelling phenomenon may occur, and water once penetrated is accumulated in a heat insulating layer (styrofoam). In addition, due to the phenomena as described above, the existing concrete layer may be cracked, or rust may be generated in the rebar. In addition, due to the cracks and rust as described above, the life of the structure can be shortened, the heat insulating effect may be lowered.

However, the structure manufactured according to the present invention can prevent the permeation of water and the permeation of air, thereby preventing the conventional problems as described above.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
