Description

Non exposure waterproof and the waterproof method with degassing and drainage

The present invention relates to a non-exposed waterproofing and a waterproofing method having a degassing and draining function, and more particularly to drying free water generated by a natural environment or deterioration between a waterproofing layer and a pressed concrete layer or a waterproofing layer and a base surface in non-exposed waterproofing. By forming a degassing and drain pipe to degas or drain the generated moisture or free water to the outside, not only prevent the deterioration of the waterproof efficiency of the unexposed water by the moisture or free water, but also by the free water The present invention relates to a new method of non-exposed rooftop structure that combines degassing and draining functions to enhance construction competitiveness by supplementing existing methods of rooftop to prevent deterioration of building durability.

In general, concrete structures such as rooftop slabs, roofs, basements of buildings, and various fluid storage tanks have weak waterproofing properties, so rainwater or groundwater can seep into the water, which not only reduces the binding strength of the concrete itself but also the moisture caused by temperature changes. The cracks in concrete occur due to the volume change of the product, shortening the life of the building.

In addition, when rainwater or groundwater is introduced or leaked through the cracks of concrete, the function of the building is lost. Therefore, waterproofing to prevent rainwater or groundwater from seeping through is very important.

The waterproof method of such concrete structure is largely permeable waterproof method and the film-type waterproof method, the waterproof method is to apply waterproofing material on the concrete surface to change the concrete itself to have waterproofness, and the film-type waterproof method It is a method to cope with the crack of concrete structure or other construction defects by forming multiple layers of impermeable waterproof layers inside and outside the structure.

And the film type waterproofing furnace is divided into asphalt waterproofing, sheet waterproofing, waterproofing coating, etc. according to the type and construction method of impervious coating material.

In addition, in the coating type waterproofing method, a waterproof layer such as asphalt or urethane is classified into an exposed type and an non-exposed type depending on whether the exposed layer is exposed to the outside or not.

1 is a partially enlarged cross-sectional view showing a conventional non-exposed waterproof structure, referring to this, the non-exposed waterproof structure is a primer layer (2) and the waterproof layer (3) sequentially on the base surface (1) and the base surface (1) ), A heat insulating layer (4), a pressed concrete layer (5, or a press mortar) and a plastering layer (or a top coating layer, 6), and as shown, the parapet (parapet) which is a vertical wall at the end of the base surface 1 The primer layer 2 and the waterproof layer 3 are further formed at a height of 1a, and the parapet 1a not only protects the waterproof layer 3 formed in the parapet 1a but also has an effect of plastering. ) And a lot of bricks are stacked between the base surface (1) to be plastered.

In addition, the waterproof layer 3 is to apply a coating by using an improved asphalt sheet or urethane, various materials are selectively used according to the use environment, and recently, the improved asphalt sheet and urethane are mainly used in combination. .

On the contrary, the exposed waterproof structure means that the waterproof layer formed on the base surface is exposed to the outside, and in the case of the exposed waterproof structure, it is mainly used in a structure in which the structure is not placed on the base surface, and the non-exposed type water tank It is a waterproof structure that is mainly used when the structure is placed on the base surface.

On the other hand, in the non-exposed waterproof structure having the structure as described above because the waterproof layer (3) is formed between the base surface (1) and the pressed concrete layer (5) outside moisture, mainly rain water is the pressed concrete layer (5) Even though the penetration into the crack or the penetration into the crack portion is absorbed by the water, further waterproof is blocked by the waterproof layer 3 to have a waterproof effect.

2 is a reference picture showing the deterioration of the conventional non-exposed waterproof structure, referring to this, in the non-exposed waterproof structure having the above structure, the rainwater penetrated through the pressed concrete layer (5) in the picture As can be seen, the water penetrated between the pressed concrete layer 5 and the waterproofing layer 3 is kept in a deceased state, and the decayed rain water (hereinafter referred to as 'free water') is pressed as time passes. There was a problem that not only lifted between the concrete layer (5) and the waterproof layer (3) but also weakened the durability of the pressed concrete layer (5).

In addition, the free water located in the waterproof layer (3) and the pressed concrete layer (5) is continuously increased over time rather than extinction as time passes, and as the building is behaving by vibration or surrounding environment, The waterproof layer 3 and the base surface 1 are damaged or partially damaged by the behavior of the building, and there is a problem of leaking of the free water through the site where the problem occurs.

As a result, when the free water between the pressed concrete layer 5 and the waterproof layer 3 is left for a long time, the durability of the pressed concrete layer 5 and the base surface 1 is weakened, and the risk of water leakage increases. Accordingly, there is a problem of lowering the waterproof competitiveness, which weakens the reliability of the non-exposure waterproof construction and general costs such as the additional cost of maintenance that must be rebuilt as a whole within a predetermined time, that is, 3 to 5 years.

In addition, the free water generated between the waterproof layer and the pressed concrete layer repeats the freezing and thawing due to the external temperature difference, thereby not only weakening the durability of the building but also lowering the thermal insulation efficiency of the building.
