Description

Double Insulation Waterproof Structure {DOUBLE ADIABATIC WATERPROOF STRUCTURE}

The present invention relates to an efficient double insulation waterproof structure having a double insulation structure and a waterproof structure at the same time.

Waterproofing of a building means a treatment method for preventing rain from leaking into a building and treating rainwater that has permeated the building. Waterproofing of a building broadly includes waterproofing the entire roof and exterior walls of the building, but generally the roof ends (corrosion), valleys, parapets or parapet walls, ceilings and walls. Refers to the treatment of leaky parts, such as around doors and windows.

Due to the remarkable development in the construction industry, large-scale construction such as highways, high-speed railways, skyscrapers, international airports, subways, and large sports stadiums is under way. However, many structures built with this economic growth often require repair / reinforcement due to cracks and leaks before they can be used. However, the repair / reinforcement is enormously incurred due to the need for repetitive repair due to re-leak, even though the cost is higher than the initial construction cost.

Among these parts, in particular, various surfaces (walls, roofs) of the building, etc., should be subjected to special waterproofing. In the concrete structure, the rooftop and the like are under the most severe environmental conditions that are directly exposed to the external environment, and thus, despite the existence of various waterproof materials, the waterproof structure that is actually applied is limited. In addition, the performance of the waterproofing material is determined not only by the characteristics of the waterproofing material but also by the condition of the wall and the external environmental requirements for waterproofing / insulation. For example, when the moisture content of the construction surface is high, the waterproofing material adheres to the construction surface, which adversely affects the performance of the material, and an air pocket is formed between the waterproofing material and the wall due to vapor pressure vaporized after construction, thereby tearing or breaking the waterproofing layer. And so on.

Thus, repair and reinforcement are needed after waterproofing, and the causes can be largely classified into the cause of the ground structure, the cause of the waterproofing material, the cause of the proficiency of the contractor, and the cause of poor design.

First, cracks may occur due to contraction or expansion of the structure due to the wall structure. In addition, the concrete wall underlying the construction of the structure is not completely dried, the water remains, the remaining water is converted into a state of water vapor to locally swell the waterproof layer, it is possible to damage the tired parts. This increases the shrinkage expansion ratio of the concrete and can cause cracking.

Defects in waterproofing can also be caused by waterproofing materials. If the waterproofing layer is weak to crack resistance, or a material weak against swelling or fatigue, defects in the waterproofing work may occur frequently. For example, the oily material may be inferior in durability or weather resistance when the heat insulation of the waterproof layer is not secured.

In addition, in the conventional waterproof construction, the dependence on the contractor is high. In the case of waterproofing the coating film, it may be a poor waterproofing work if the compounding ratio between materials is not accurately observed or if sufficient curing time is not given.

In particular, workers should be fully aware of the importance of waterproofing work and perform precise construction, but there is a high risk of under-work due to lack of worker's awareness of construction quality, and in reality, securing high quality equipment and functional personnel due to the low cost of waterproofing work. Because of this difficulty, it is not easy to overcome the secondary construction in waterproof construction.

Of course, even in the design stage of waterproofing, defects in waterproofing may occur if the necessary environmental requirements of the part to be waterproofed are not taken into consideration, or detailed design such as small holes, joint and drain positions of material property management for materials are omitted. .

In addition, another conventional waterproof structure has a structure that exhibits a water-proofing effect to some extent by melting by heat such as a torch lamp to the joints overlapping between the waterproof sheet of each sheet to be mutually welded.

However, since the joints, which are the connection parts between the respective waterproof sheets, are melted and welded with heat such as a torch lamp, the joints may not be uniformly attached and have a double or triple waterproof and insulation structure. There is a problem that the connection parts between each layer are all located at the same location, so that moisture and water from the outside may flow directly into the waterproof / insulation layer and the concrete wall, which is the base surface for the waterproof / insulation layer, through the connection part. there was.

Therefore, in the conventional waterproof structure, first, because the joints overlapped between the waterproof sheets of each sheet are welded by melting them with a heat such as a torch lamp, the waterproof layer is accelerated due to overheating and is not partially welded due to mild heat. And moisture and moisture infiltrate the heat insulation layer, and even in the case of a plurality of double or triple sheets stacked, moisture and moisture penetrate through the joint part. Second, the soil may be melted by heat at the joint part. There is a problem of deterioration of work efficiency due to the possibility of fire or burn by accompanying additional equipment such as lamp lamp, gas cylinder, gas pipe, etc. Third, because the joints are overlapped to continuously install waterproof and insulation sheet It is difficult to find the leaking part in case of a defect. There was a problem.

The present invention has been made to solve the above problems, the object of the present invention is the primary insulation waterproof layer made of an integral layer of the adhesive layer and the heat-resistant waterproof sheet, the reinforcing cloth, the heat-resistant waterproof sheet, the secondary insulation layer forming the adhesive layer integral. Consists of a double coating structure of the waterproof layer to increase the effect of thermal insulation, and by forming a coating waterproof layer on the upper surface of the first and second thermal insulation waterproof layer to add a waterproof effect to prevent the penetration of moisture and moisture from the outside, a number of 1 The secondary insulating waterproof layer and the plurality of secondary insulating waterproof layers are bonded to the concrete layer while being disposed so as not to be mutually coincident with each other to adhere to the concrete layer, to provide a double insulating waterproof structure to block the inflow of moisture and moisture through the connecting portion. .
