Description

Heat insulating and waterproofing method of rooftop area and complex panel for heat insulatiing and waterproofing works}

The present invention relates to a heat-insulating waterproofing method and a composite waterproofing material for thermal insulation, which is constructed for heat insulation and waterproofing on a roof of a building, and more particularly, to maintain durability while maintaining a simple construction even for a building already completed by a post insulation method. It relates to a heat insulation waterproof method and a composite plate for heat insulation waterproof in a singular form that makes it easier to construct such a heat insulation waterproof method.

The insulation method used to increase the insulation performance of the building is divided into insulation, exterior insulation and breakdown heat according to the location of the insulation. Among them, the insulation insulation method attaches insulation to the exterior of the building, It is possible to completely cover the exterior of the building with insulation as a method of finishing the exterior of the insulation with an external finishing material that can supplement the impact resistance. There is a big advantage that it can be installed.

However, there is a problem in that the insulation performance of the insulation is significantly degraded when the insulation gets wet due to cracking or absorption of the exterior finish material. have.

On the other hand, building insulation is classified into inorganic type such as glass wool and mineral wool, and organic type such as urethane, polystyrene, polypropylene, and polyethylene, depending on the type of constituent material. It depends a lot on the action of gas components such as these. Therefore, in order to exhibit a high degree of heat insulating properties, regardless of the material, for example, a foam structure has a form in which gas components are evenly dispersed therein. Due to this structure, all insulations are light, but they have a weak physical strength which is a common physical feature.

Due to the physical characteristics of the insulators having low strength and durability, various external insulation methods such as dry bit, sheet insulation method, etc. have been developed and widely used for walls and roofs of a certain height that are relatively unaffected by buildings. Most of the rooftops that require high durability or installation of resting spaces or the creation of greening spaces are constructed by heat-resistant insulation method. However, in the case of existing buildings, construction is difficult due to the heat insulation method or the interrupted heat method, and there is no proper heat insulation method for improving insulation.

Therefore, research has been conducted to develop a construction method for solving the waterproofing, which is essential for the rooftop, in addition to the insulation construction on the roof of the existing building. No easy and durable method has been developed.

For example, in Korean Laid-Open Patent Publication No. 1999-32487, after forming a longitudinal groove in a foam molding resin which is a heat insulating material, and filling the resin-reinforced cement mortar with a reinforcing material, and filling the rest of the outside except the bottom surface There is disclosed a dry construction method for forming a mortar layer, and providing a panel having a flexural strength and a surface impact strength having a synthetic resin layer formed thereon to be used for condensation walls of a roof, a floor, an inner wall, an outer wall, and a retaining wall of a basement. .

However, cement mortar is easily broken even in small deformations. When this method is applied to the floor of a building roof, deformation of the internal foam molding resin is induced by the force applied from the upper part and is connected to the groove of the insulation. There is a problem that the crack of cement mortar occurs. In addition, a relatively thick cement mortar layer is required to withstand external forces so that such a problem does not occur, and in the case where the cement mortar is separated by cracks, there is a high possibility that the top waterproof layer is damaged. .

On the other hand, Korean Laid-Open Patent Publication No. 2005-9769 introduces a heat insulating, waterproof, soundproofing agent and a coating method formed by applying a low-foaming polyurethane to form a urethane foam, and then applying a high-speed curing polyurea layer. However, as described above, in order to expect high heat insulating properties, it is required to contain a large amount of gas, and when a large amount of gas layer is contained, the compressive strength is significantly lowered. Does not provide an effective way to solve such problems. Therefore, there are many limitations in the utilization of the roof space because only the load in the range that does not damage the urethane foam layer after construction on the roof is allowed, and the settlement of the lower foam urethane layer occurs when the load is applied from the upper part, There is a possibility that the urea waterproof layer is destroyed, so the durability of the waterproof layer is also difficult to expect.

As such, there is no roof top insulation method that effectively reinforces the low strength and low durability of the insulation so that people can freely enter and use the roof space after the heat insulation work. In order to prevent breakage of the building and to stably protect the lower insulating layer, no thermal insulation waterproofing method has been developed for the rooftop of the building, which does not cause deterioration of thermal insulation due to moisture penetration.

The present invention has been made to solve the above-mentioned problems of the prior art, an external insulation method that can be effectively applied to the space of the rooftop people freely enter and the waterproof method that can prevent the damage of the waterproof coating layer existing on the upper portion of the insulation. It is an object of the present invention to provide a durable rooftop insulation waterproofing method that is effectively combined.

The present invention also provides a roof insulation insulation waterproof method can be easily installed with little manpower and effort, as well as to provide a thermal insulation waterproof composite sheet excellent in stability and durability of the constructed insulation waterproof coating layer.

Roof insulation thermal method according to the present invention for solving the above problems,

A process of forming an insulating layer and a reinforcing layer at a time by applying a composite plate of a form in which an inorganic plate reinforcing compressive strength is fixed to an upper portion of the expanded polystyrene sheet serving as a heat insulating material on the floor of a roof to be constructed;
Forming a buffer layer by spreading a fiber cloth or a waterproof sheet on the inorganic plate-like material of the composite plate; And
It characterized in that it comprises a step of forming a waterproof coating layer by applying a liquid waterproofing agent on top of the fabric cloth or waterproof sheet.

In addition, when the slab on the rooftop to be constructed is old and contains a lot of moisture or when the rooftop slab for a new building is not completely dried and the function of waterproofing should be particularly excellent, the foamed polystyrene is used as the composite plate. In the process of forming the heat insulating layer and the reinforcing layer at the same time by using a form in which the drainage plate having irregularities formed on the bottom surface of the lower part of the plate is fixed, the drainage layer may be further formed at the same time. It can be constructed in a form that makes it waterproof.

In the roof insulation waterproof method, the process of forming the drainage layer, the process of forming the insulation layer, the process of forming the reinforcement layer, and the process of forming the buffer layer may be separately performed sequentially during the construction of the insulation waterproof method, In the present invention, as described above, by carrying out two or more processes at a time using a composite sheet material, construction convenience is achieved.

That is, by using a composite plate of the form in which the inorganic plate is fixed to the upper portion of the foamed polystyrene sheet, the insulating layer and the reinforcement layer are formed at a time, or the inorganic plate is fixed to the upper portion of the foamed polystyrene sheet, the foamed polystyrene plate and the inorganic plate It is also possible to form a heat insulating layer, a reinforcing layer and a buffer layer at a time by spreading a composite plate of a type in which fiber cloth covering the top of the water is integrated on the floor of the roof to be constructed. However, the formation of the waterproof film layer is made by applying a liquid waterproofing agent on the solidified after the above each layer is constructed.

On the other hand, the composite composite material for waterproofing waterproofing according to the present invention used in the roof insulation waterproofing method for the rooftop, the inorganic plate-like material to reinforce the compressive strength of the foamed polystyrene sheet is fixed to the upper portion of the foamed polystyrene sheet to act as a heat insulating material It features.

Preferably, in order to further simplify the construction, the composite fabric for heat-resistant waterproofing is manufactured in an integrated form by laminating fiber cloth or waterproof sheet so as to cover them on top of the expanded polystyrene sheet and the inorganic sheet.

The expanded polystyrene sheet material and the inorganic sheet material and the fiber cloth or waterproof sheet may be in the form of an integral one by adhering to each other by an adhesive, the inorganic plate-like article and the fiber cloth or waterproof sheet is integrated during the foam molding process of the foamed polystyrene sheet to the upper part of the molding It may be in the form of a laminated insert.

In addition, in any of the above-described composite plates, it is also possible to produce and use a composite heat insulating waterproof sheet having a shape in which a drain plate is integrally fixed to the lower portion of the expanded polystyrene sheet.

According to the roof insulation waterproofing method according to the present invention, since inorganic plate-like objects such as porcelain tiles or cement boards form a reinforcing layer on the upper side of the expanded polystyrene sheet used as a heat insulating material, a high load installation is installed on the roof or a person. Even if a situation such as frequent travel occurs, the reinforcement layer distributes the compressive force acting locally concentrated on the upper portion of the insulation to a large area, thereby effectively supplementing the low physical strength of the foam insulation. There is an advantage to that.

In addition, by forming a buffer layer by attaching a fiber cloth such as a high-strength fabric or a nonwoven fabric to the upper portion of the inorganic plate-like forming the reinforcing layer, when the liquid waterproofing agent is applied to form a waterproofing layer, the liquid waterproofing agent penetrates into the porous fiber cloth. By solidification, it is possible to form a waterproof coating layer having excellent airtightness and strength.

In addition, since the fiber cloth or the waterproof sheet exerts a buffering effect on the layers existing under the interaction with the highly elastic waterproof agent, it is possible to effectively prevent the breakage of the fragile inorganic plate. In particular, in the case of using a fiber cloth, even if a crack occurs due to an external impact on the inorganic plate material, the high-strength fiber cloth is integrated with the inorganic plate material to effectively fix it, and reinforce the waterproof film layer sufficiently to prevent damage of the waterproof film layer. As a result, the uppermost waterproofing layer can be protected.

On the other hand, the composite sheet for thermal insulation waterproof used in such a roof insulation waterproof method is a foamed polystyrene sheet, an inorganic plate and a fiber cloth or waterproof sheet to form a thermal insulation layer, a reinforcing layer and a buffer layer is provided in a single unit form, so that the contractor Laying the plate on the roof and applying the liquid waterproofing agent on the roof makes it possible to complete the construction of the insulation waterproofing method. This composite plate material can greatly reduce the manpower and time required for the construction of the insulation waterproofing method. have.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

1A to 1E are diagrams sequentially illustrating a construction process of a roof insulation insulating method according to a first embodiment of the present invention.

Referring to Figures 1a to 1e, when explaining the process of constructing the roof-top insulation waterproof method according to the first embodiment of the present invention, first to clean and remove the foreign matter on the floor (S) of the roof to be constructed, As shown in FIG. 1A, the foamed polystyrene sheet 10 having excellent heat insulating properties and excellent compressive strength is laid as a whole to form a heat insulating layer.

And as shown in Figure 1b, by applying an adhesive (B) on top of the expanded polystyrene sheet 10, by forming the inorganic plate-like article 20 in the form of ceramic tiles to form a reinforcing layer. As the inorganic plate 20, a reinforcing layer may be formed using a cement board or a magnesium board instead of the ceramic tile. Inorganic platelets are more preferable in terms of preventing cracks or breakage of small ones smaller than 10 cm in width and length rather than wide.

Next, as shown in Figure 1c, to apply the adhesive (B) to cover the upper portion of the inorganic plate 20 and to attach a fiber cloth 30 in the form of high-strength fabric cloth thereon to form a buffer layer. The fiber cloth 30 acts as a cushioning material to prevent breakage of the inorganic plate 20 and at the same time serves to improve the airtightness and strength of the waterproof coating formed thereon. Instead of the high-strength woven fabric, the fiber cloth 30 may also be a knitted fabric or a nonwoven fabric. Particularly, in the case of the nonwoven fabric, the strength is weaker than that of the high-strength fabric, but the thickness is relatively thick, and the pores formed between the fibers are relatively constant, thereby making it possible to form a more uniform, thicker and airtight waterproof coating film. Excellent cushioning effect against the compressive force also has the effect of preventing breakage of the reinforcing layer.

In addition, it is also possible to form a buffer layer by laying a waterproof sheet (not shown) in place of the fiber cloth (30). As the waterproof sheet, an SBR rubber sheet, a natural rubber sheet, an EPDM sheet, a PVC sheet, and the like, which are commonly used in a waterproofing method, may be used, and a buffer layer may be formed directly on an inorganic plate without applying an adhesive.

As shown in FIG. 1D, the fiber cloth 30 is coated with the liquid waterproofing agent 40 and solidified to form a waterproof coating layer in the form of a coating film. As the liquid waterproofing agent 40 forming the waterproofing coating layer, a known liquid coating waterproofing agent such as a one-component or two-component polyurethane waterproofing agent, an acrylic one-component coating waterproofing agent, a polyurea-based two-component coating waterproofing agent may be used.

Other constructions may be added to the top of the waterproof film layer.

In the present embodiment, for the purpose of the composition of the roof garden through the planting of the plant, as shown in Figure 1e to apply the adhesive (B), and further added to the root sheet 50 that prevents the penetration of the plant roots to further form a root layer It was. It is also possible to form a barrier layer by applying a liquid barrier member in place of the barrier sheet.

Laying and coating the liquid waterproofing agent 40 thereon as shown in FIG. 2B and solidifying it to form a waterproof coating layer in the form of a coating film, the adiabatic waterproof construction is completed.

Therefore, when the construction using the composite plate as in the present embodiment, it is possible to complete the construction simply by laying the composite plate (1A) and applying a liquid waterproofing agent and solidifying without going through several steps, greatly reducing manpower and time There is an advantage to this.

Here, the thermal insulation waterproof composite plate 1A is applied to the lower portion of the expanded polystyrene plate 10, which is a heat insulator, the adhesive (B) is attached to the bottom plate attached to the drainage plate formed with irregularities on the bottom surface of the expanded polystyrene plate (10) The adhesive (B) is applied to the upper part, and the inorganic plate-like material 20 in the form of a ceramic tile is attached thereto, and then the adhesive B is applied thereon, and the fabric cloth 30 is attached and integrated. Can be modified in the same manner as described in the above-described first embodiment. Then, in order to prevent the gap between the connecting portions of the heat insulating waterproof composite plate 1A during construction, as shown in the figure is formed by forming a step (E) or teeth to be manufactured to closely interlock between the edges.

The drainage plate 60 is installed only when the slab on the rooftop to be constructed is old and contains a lot of moisture or when the rooftop slab for a new building is not completely dried and the waterproofing function must be particularly excellent. In principle, the above-described insulation waterproof composite plate material 1A is manufactured and constructed in a form without the drainage plate 60.

However, in the heat insulating waterproof composite plate 1B of the present embodiment, the inorganic plate-like article 20 in the form of ceramic tiles and the fiber cloth 30 'in the form of a nonwoven fabric are not bonded to each other with an adhesive. In the foam molding process, the foamed polystyrene sheet 10 is integrated with the foamed polystyrene sheet 10 so as to be laminated on one surface of the molding.

4A through 4D, as shown in FIG. 4A, a nonwoven fabric fiber 30 ′ is introduced into a molding mold of the polystyrene foam molding machine 100, wherein the fiber cloth 30 ′ is formed on the fabric cloth 30 ′. The inorganic plate 20 supplied through the separate supply device 101 is placed at predetermined intervals and introduced into the foam molding machine together with the fiber cloth 30 '. Then, polystyrene (EPS) particles 11, which have been pre-foamed as shown in FIG. 4B, are added thereto.

Then, as shown in Figure 4c, when the high-temperature, high-pressure steam is supplied, while the polystyrene particles 11 soften and expand, not only the expanded polystyrene particles 11 are fused together, but also the expanded polystyrene particles 11 ) Penetrates the gap between the inorganic platelets 20 and further penetrates between the fibers of the fiber cloth 30 ', thereby filling the voids and is attached to and integrated with these inorganic platelets and the fiber cloth.

In addition, the inorganic plate-like material 20 and the fiber cloth 30 'are pressed onto one surface of the expanded polystyrene molded into a plate shape and cooled when the molding of the insulation waterproof composite plate material 1B of the laminated insert is completed, as shown in FIG. 4D. As it is discharged to the foam molding machine 100 outside. After the molding is completed, it is shipped to the desired shape through a suitable cutting process.

However, in order for the expanded polystyrene particles 11 and the ceramic tile and the nonwoven fabric used at this time to adhere well to each other, the ceramic tile or the nonwoven fabric is more preferably manufactured in the form of irregularities on the surface thereof. And the thing which apply | coated or impregnated the adhesive component adhered by the steam of high temperature and high pressure to the said nonwoven fabric or a ceramic tile can also be used.
