Description
The present invention relates to a flame retardant drainage method for constructing a basement or an underground building, and more particularly, to a flame retardant drainage method for building a basement of a building or the like for preventing leakage, crack, The present invention relates to a construction method capable of being installed very quickly for the purpose of flame retardation,
Generally, in the underground space, not only the leakage and crack phenomenon but also the difference in temperature between the air and the air, the condensation phenomenon occurs in which the moisture in the air is condensed into the temperature difference between the air temperature and the wall surface.
Conventionally, in order to prevent such condensation and moisture, the inner wall of the underground space is closed. First, there is a method of directly insulating the inner wall of the underground space and attaching a gypsum board thereon. Second, A method of directly applying paint or the like, and a method of building a double wall by stacking bricks again inside the underground space and filling the insulation therebetween, or attaching a heat insulating material and a gypsum board to the wall of the double wall .
However, according to these conventional arrangements, there is a problem in that the degree of heat insulation is insufficient and the condensation phenomenon caused by leakage and cracks is fundamentally insufficient, so that the problems such as the flow of water due to the condensation phenomenon and the generation of mold are completely solved There is a problem in that it is necessary to additionally attach or apply a separate finishing material to the surface of the heat insulating material which is basically installed, and thus it is costly and time-consuming to construct the heat insulating material.
In addition, there are many cases where the insulation is insufficient and the insulation is missing in the gaps, so that the coating material or the wall material that has finished the inner wall is damaged or damaged. Thus, a lot of maintenance and repair costs have been wasted. And there is a problem that it is harmful to health. In case of installing a separate inner wall, the effect is excellent, but it has a lot of disadvantages such as wasting a very large space, a great construction cost and construction time.
The prior art related to the drainage method of the conventional underground wall is disclosed in Korean Patent Laid-Open Publication No. 10-2001-0008914, wherein a drainage plate and a drainage plate for guiding and discharging the groundwater, Type projection and a higher Π-shaped projection are alternately repeatedly formed at a regular interval on the surface of the substrate, and the I-shaped projection is repeatedly formed on the other surface of the substrate at regular intervals. And a method of inserting a drainage pipe into a mat base section using a hexa tube connector is disclosed in Korean Patent Laid-Open Publication No. 10-2002-0033686, If necessary, the wastewater in the basement is introduced into the house keeping. The present invention relates to a method for draining a Hexa tube connector, which discloses a method of draining Hexa tube connectors, and Korean Patent Laid-Open Publication No. 10-2010-0103027 discloses a Hexa tube connector drainage method, A floor finishing concrete layer is formed so as to form a space wall having a predetermined distance from the underground retaining wall so as to have a drainage passage and a second drainage passage connecting the bottom of the foundation bottom concrete layer to the collection wall from the first drainage passage, And forming a grating portion including a plurality of slots in a space wall portion in contact with the upper portion of the bottom-finishing concrete layer so that water on the upper portion of the bed flows through the first drain passage through the collecting hole, have.
However, the above-described prior arts use a method of using a drain pan or inserting a drain pipe, or using a drain pan because of the use of a drain pan, resulting in a problem of being vulnerable to fire, a long construction time, and a large installation cost.
Therefore, we have constructed an eco - friendly flame - retardant drainage method that is resistant to fire due to the absence of a drain plate, does not cause cracks to regenerate due to epoxy coating, eliminates the need for wall piercing, shortens the construction period,
The present invention solves the above-mentioned problems and further complements the conventional techniques. Since the plastic material such as a drain plate is not used, the incombustibility and the flame retardancy can be improved, and the construction time is shortened because the wall is not required to be drilled. The purpose of this simple underground wall flame retardant drainage method is to provide.
As a solution for achieving the object of the present invention, there are a foreign matter removal step for removing foreign matter on a construction surface, a water-soluble epoxy priming step for applying a water-soluble epoxy, a leakage and a crack part of the wall by using a urethane foam expansion method and an injection water- And a cracked urethane injection step and a water-soluble epoxy intermediate step of applying a water-soluble epoxy, a water-soluble epoxy-applied silica-applied step of spraying silica-coated water-soluble epoxy coated surface with the water-soluble epoxy- (Polyethylene net), applying a mortar containing cement, sand and water, a water-soluble epoxy topping step for applying a water-soluble epoxy, and a stone and dry-bit finishing step for external wall insulation.
First, remove foreign matter and dust on the construction surface, and apply water-soluble epoxy. At this time, epoxy is applied for dustproof and abrasion resistance, and to prevent cement dust and cement from being cracked on the construction surface. When leakage occurs in cracks, joints, etc. of concrete structures, leakage and crack urethane injection work are carried out to repair and repair leaks by reacting with moisture inside cracks. Also, water-soluble epoxy is applied and silica sand is sprayed at the same time. Thereafter, a P.E net (polyethylene net) is applied, the mortar is applied, the water-soluble epoxy is applied, and the end is subjected to a step of stone and dry bit finish.
When the underfloor flame retardant drainage method of the present invention is used, it is possible to eliminate the fragility of the wall because the wall drainage plate by the existing method is made of the plastic material, and the crack portion of the wall is epoxy-coated, It is necessary to construct an anchor on the wall surface in order to support the drainage plate in the construction of the wall drainage board. However, the present invention does not require a wall piercing such as anchorage construction, shortens the air and simplifies construction, .
Hereinafter, the present invention will be described in detail, but the present invention is not limited by the following description.
