Description

Water-proofing method using Ventilation panel

The present invention relates to a waterproof construction method of applying an asphalt sheet used for waterproof construction of a floor or a wall, and applying a structure capable of maximizing breathability.

In general, inorganic materials, such as concrete or mortar, that form a building, may generate cracks due to hydration heat or various vibrations due to the hydration reaction of cement, resulting in leakage and condensation due to the breakage of waterproof materials, etc. There is a structural problem that the durability of the building is further weakened to promote aging.

In order to prevent or repair such cracks in concrete structures, a waterproofing method is implemented. The waterproofing method has been improved, developed, and changed in material and method performance, but to date, the existing waterproofing method is in operation and continues to generate defects. That is, the inorganic waterproofing method, such as the cement liquid waterproofing method and the inorganic elastic coating film waterproofing method, has a problem of high crack generation due to deterioration of bonding performance, behavior, and vibration by using inorganic powder other than cement as a main material.

In addition, organic waterproofing methods, such as urethane coating waterproofing and asphalt coating waterproofing, are in practical field application, and the adhesive performance decreases according to the moisture content of the ground surface, formation of a non-uniform waterproofing layer, and defects due to failure to comply with construction standards occur. There is a structural problem that weakens the durability of the structure due to water leakage.

In order to solve these structural problems, various methods have been applied, and there are a sheet waterproofing method using a waterproof sheet, a coating waterproofing method using a urethane or an asphalt coating material, and a composite waterproofing method in which the sheet and the coating material are double applied.

For example, the sheet waterproofing method is a method of attaching a waterproof sheet to a floor surface of a structure such as a rooftop of a building to form a waterproof layer. Specifically, a waterproof sheet of a certain standard such as PVC sheet or rubberized asphalt sheet is installed on the roof of a building. It is a construction method that spreads on the floor of a construction structure such as a construction.

That is, the waterproof sheet is manufactured in the form of a roll-shaped sheet having a standardized width and length (typically 1 to 1.2 m in width and 10 m in length), which is laid on a floor (or'base surface') at regular intervals to be laid. do.

In this case, the joint between the waterproof sheets is generated, and if the joint is not properly treated as a vulnerable site for waterproof performance in sheet waterproofing, the cause of the waterproof defect causes problems of construction defects.

Specifically, when the water vapor pressure caused by the moisture contained in the concrete base layer to be the construction target surface is generated and thus the discharge of such water is not smooth, the problem of lifting the waterproof sheet occurs, especially in the joint portion of the waterproof sheet. This excitement is further exacerbated and a problem that leads to the fracture of the sheet layer itself occurs.

To solve this, attempt to enhance the breathability of the waterproof sheet itself using a soft film such as a polyethylene film, or to solve the excitement problem caused by the generation of water vapor pressure with a waterproof sheet structure using a non-woven fabric having large irregularities. Although attempts have been made, the problem of fracture of the joint due to the increase in the air layer in addition to water vapor in the sheet itself due to the aging of the material of the sheet itself over time and heat generation in a high temperature environment is a problem that is fundamentally difficult to solve.

FIG. 3 is a side cross-sectional conceptual view of the main configuration of FIG. 2.

1 to 3, the present invention is a first step of arranging a ventilated panel having a horizontal to vertical ratio of 1: (2 to 3) on the construction target surface (A), and the construction target surface (A) Step 2, the adjacent portion (B) in which a plurality of improved asphalt unit sheets are arranged adjacent to each other, and the central portion of the vented panel is arranged in a structure corresponding to the central portion in the longitudinal direction of the adjacent portions (B, C). , C) 3 steps of forming a glass fiber layer along the longitudinal direction, and 4 steps of laminating a coating layer on the plurality of improved asphalt unit sheets and vented panels.

Specifically, in the first step, the construction target surface (A) is a concept that includes both a construction floor surface such as an outer wall, an inner wall, a roof of a building that requires waterproof construction, or a waterproof construction site to a structure of an externally exposed place. to be. Preferably, a place where the construction target surface is made of a concrete structure will be described as an example. In the case of the concrete floor surface, the phenomenon that moisture contained inside rises to the surface due to geothermal heat and external heat is extremely intense, and at the same time, the air contained inside also rises to the surface. This is because moisture is not discharged, which is the object that causes the most problems of lifting or breaking the waterproof sheet.

In the first step of the present invention, the operation of arranging a surface to be constructed to constitute a surface in a state where a waterproof sheet can be seated is included, and operations such as removal of a contaminant and flattening of a part of a place having protruding problems are included. do. That is, with respect to the construction target surface, the lattice or foreign matter is removed, and the cross-section repair is performed for a place such as a crack or a recess to maintain the flatness of the ground surface. Of course, depending on the case, depending on the operator's choice, the crack may not be severe or the waterproof layer may be formed without performing cross-section repair.

After arranging the construction target surface, first, an area in which a plurality of unit sheets made by cutting an improved asphalt sheet according to the present invention is arranged is designed, and adjacent portions of adjacent unit sheets are mutually adjacent boundaries (FIGS. 2 and B). , C) Arrange the ventilated panel in the area to be placed.

The ventilated panel in the present invention has a first surface and a second surface opposite to the first surface, and refers to a structure of a flat plate structure in which the plane is a rectangular parallelepiped structure. It is preferable to apply a plate structure having a rectangular structure with a plane shape of 2 to 3). It is preferable to use a stainless steel panel having excellent anti-rust properties and excellent durability, but it is not limited thereto, and it is also possible to apply a structure in which anti-rust plating (for example, zinc plating) is implemented on a metal panel.

The process of pre-positioning a ventilated panel on the construction target surface (A) is a key point of the present invention, and prevents the phenomenon of being released between the moisture rising from the inside of concrete and the improved asphalt sheet, which will be described later, and not being discharged to the outside. , Efficiently move to the place where the ventilation pipe is located, enabling self-discharging, thereby realizing the effect of blocking the excitation of the seam between the unit sheets in advance.

That is, in the construction process of the present invention, a ventilation panel is designed and arranged on the target surface in one step, and in the second step, a plurality of improved asphalt unit sheets (10, 20, 30) locks are arranged on the target surface (A). However, it can be arranged in a structure corresponding to the central portion of the longitudinal direction of the ventilation panel (110A, 110B, 120A, 120B, 130A, 130B) (see FIG. 2).

Specifically, referring to FIGS. 2, 3, and 4, the ventilation panels 110A, 110B, 120A, 120B, 130A, and 130B are structures in which a plurality of unit sheets are disposed adjacent to each other (B), Particularly preferably, the central portion of the ventilated panel is arranged to correspond to the central portion in the longitudinal direction of the adjacent portions (B, C), and at the same time, the longitudinal direction of the adjacent portions (B, C) and the longitudinal direction of the vented panel. It is desirable to arrange them so that they are orthogonal to each other.

That is, as shown in Figure 2, the unit sheet (10, 20, 30) is to be implemented in a structure having a long direction (first direction: x) and unidirectional (second direction: y), Figure 2 Although the arrangement of the three sheets of the unit sheet is illustrated in the structure of, the present invention is not limited thereto, and a plurality of unit sheets are continuously arranged according to the construction site.

Considering the adjacent portion B in the first direction in the long direction (x) in FIG. 2, the pair of unit sheets 10 and 20 is an adjacent portion to be implemented, and two vented panels 110A and 110B are arranged. In this case, the sizes and configurations of the vented panels 110A and 110B are all implemented in the same manner, and in the arrangement position, the first adjoining portion B formed in the longitudinal direction is the first adjoining portion ( It is preferable to divide B) into four and arrange them in the outer divided space regions d1 and d4 The number of ventilated panels disposed in the outer divided space regions d1 and d4 are both respectively in the illustrated structure. Although one by one is illustrated, depending on the characteristics of the construction site (drainage channel arrangement, drain pipe reclamation location, etc.), a permeable panel of the relevant part can be added to the place where it is expected that there will be a large amount of water infiltration on the concrete surface. have.

Further, in the case of a ventilated panel, considering the virtual center line in the longitudinal direction of the adjacent portion B, the arrangement structure of the ventilated panel is preferably arranged such that the above imaginary line passes through the center of the ventilated panel. At the same time, it is possible to maximize the mobility of moisture or air under the seat by arranging such that the longitudinal direction of the adjacent portions (B, C) and the longitudinal direction of the ventilated panel are orthogonal to each other.

In general, in the case of an air layer or a moisture layer that is moored under the waterproof sheet, it moves toward the edge of the waterproof sheet according to the characteristics of the fluid (when the volume expands due to thermal diffusion, the fluid moves to the edge region). , Due to the arrangement of the ventilated panels arranged in the outer divided space areas (d1, d4), the air and moisture moved toward the border move along the lower portion of the adjacent unit sheet, and eventually through a degassing pipe. It is easily discharged to the outside.

Arranged so that the longitudinal direction of the adjacent portions (B, C) and the longitudinal direction of the ventilated panel are orthogonal to each other, when the inclined arrangement of the ventilated panel disposed on the starting target surface is inclined, the unit sheet on the seam disposed on the upper part The contact surface of the non-uniform, it is not possible to exert a uniform support of the unit sheet, the contact surface (a1, a2) of the adjacent pair of the unit sheet and the ventilated panel (110A) must be made uniform to contact the entire surface of the unit sheet The support force of the ventilated panel is made uniform, and accordingly, the contact pressure between the unit sheet and the construction target surface is made uniform, so that the edge movement of the fluid can be easily spread. Therefore, the second adjacent portion C formed in a unidirectional manner allows a ventilated panel to be arranged at the center of the second adjacent portion C, and at the same time, the longitudinal direction of the adjacent portion C and the ventilated panel. It is preferred that the long direction of the be arranged so as to be orthogonal to each other, so that the contact surfaces b1 and b2 of the pair of unit sheets and the ventilation panel 110A are made uniform.

As an embodiment in the present invention, in the case of the ventilated panel, a structure in which a rust-preventing material is coated on a plate made of stainless steel (SUS) or a metal is applied, and having a flat size of 7 cm in width and 14 cm to 15 cm in length is applied. can do. If necessary, a structure in which a ventilation guide pattern is implemented in the longitudinal direction of the ventilation panel may be applied to the bottom surface of the ventilation panel so as to correspond to the direction of air flow. In the case of the ventilation guide pattern, it is possible to implement a structure in which a plurality of regular groove structures are implemented on a panel surface in a stripe shape. The arrow in FIG. 2 conceptualizes the movement paths R1 to R4 of air and moisture, and illustrates the flow of air R discharged to the outside through the degassing pipe Y.

FIG. 4 shows the arrangement structure of the unit sheet and the ventilated panel when the simple unit sheet structure of FIG. 2 is expanded to a plurality.

As shown in FIG. 4, a structure in which two vented panels are arranged at the edge portion in the adjacent portion B in the longitudinal direction, and one vented panel is arranged at the central portion in the uniaxial portion C, is continuous. It can be constructed to be implemented as. In this case, in the case of a ventilated panel to be applied, it is possible to arrange the size in the same standard as the above-described embodiment in FIG. 2.

In addition, the improved asphalt waterproof sheet 10 applied to the present invention, as shown in Figure 5, the surface to be in contact with the construction target surface (A), the silica layer 2, and the silica layer 2 stacked on It can be applied to the asphalt layer 4, which is implemented in a structure having a nonwoven fabric layer 8 laminated on the asphalt layer.

The silica sand layer 2 may be a sheet layer containing silica sand, and may be applied to a structure in which a silica material layer mixed with a certain concentration of an adhesive material is formed on the surface of the asphalt layer 4. The silica layer (2) is a surface that is in direct contact with the construction target surface (A), and has a large surface area and a wide surface gap, thereby increasing the contact area with the concrete floor to increase adhesion, and the generation of bubbles or moisture Even when it occurs, it plays an important function of the surface layer in terms of allowing the fluid to move easily along the surface.

An asphalt layer 4 is provided on the silica sand layer 2. The asphalt layer 4 is made of a material capable of maintaining waterproof performance even for a long time with temperature sensitivity having a change in the properties of a solid-gel state according to a change in temperature, and has various viscosity ranging from a viscous liquid to a smooth solid. It is a material similar to black or brown petroleum, and is mainly composed of an asphalt material composed of a compound of hydrogen and carbon, a small amount of nitrogen, sulfuric acid, and oxygen. Normally, asphalt has a natural asphalt containing minerals, and the residual petroleum asphalt remaining after distilling petroleum does not contain minerals, and becomes soft when heated and elastic under certain conditions. Thus, in the case of the asphalt sheet of the present invention having an asphalt layer, even if a behavior such as shock or vibration occurs in the building, it is self-healing property that absorbs it by its own elasticity, and is waterproof as it is prevented from breaking or tearing through long-term use. Performance will be maintained.

The nonwoven fabric layer 8 is provided on the asphalt layer 4. The nonwoven fabric constituting the nonwoven fabric layer 8 secures an insulating layer with a base surface, absorbs and disperses water vapor or moisture generated from the base surface, and increases the internal pressure of the insulating layer generated by the water vapor or moisture. By preventing the occurrence of defects such as swelling due to the increase in the internal pressure, it performs a function to support the waterproof performance is maintained. The nonwoven fabric layer 8 is disposed on the silica sand layer 2 and the asphalt layer 4, and exerts a heat insulating performance due to air permeability, thereby performing an auxiliary function of suppressing the generation of water vapor due to a temperature difference. As a fabric material for implementing such a nonwoven fabric layer, in the case of a nonwoven fabric, polyethylene spunbond nonwoven fabric, polypropylene spunbond nonwoven fabric, polyester spunbond nonwoven fabric, polyester spunbond nonwoven fabric and polypropylene spunbond nonwoven fabric are combined. Bicomponent nonwoven fabric, bicomponent nonwoven fabric with polyester spunbond nonwoven fabric and polyethylene spunbond nonwoven fabric, bicomponent nonwoven fabric with polypropylene spunbond nonwoven fabric and polyethylene spunbond nonwoven fabric, thermal bond nonwoven fabric, rayon nonwoven fabric, etc. Any one or two or more may be used.

After arranging a plurality of unit sheets as the first and second steps in the present invention, a three-step process attaches a glass fiber layer to the adjacent portions (B, C) along the longitudinal direction so that both sheets can be first fixed. . The long-term glass fiber layer is an adhesive material member containing glass fibers in a permeable and breathable adhesive sheet material having a width of about 10 cm or more, and is attached along the longitudinal direction of the adjoining portion so that both adjacent unit sheets can be fixed. Bars comprising glass fibers, the air permeability is good, it is realized the advantage of being able to maintain the adhesive function.

Thereafter, as a process, four steps of laminating a coating layer on a plurality of improved asphalt unit sheets and vented panels are performed.

In the case of the coating layer, polyurethane or urethane-based rubber may be used. Of course, the present invention is not limited thereto, and the coating material may be selected according to the purpose of waterproofing or use. It has a difference in composition content depending on exposure and non-exposure.

For example, in the case of exposure, the coating material composition of the coating layer 30 is 20 to 23 parts by weight of a polyurethane copolymer, 11 to 19 parts by weight of polypropylene glycol, and 8 to 18 parts by weight of dioctylphthalate (DOP, di-octyl) It is a high-performance urethane coating waterproofing material composed of phthalate), 25 to 40 parts by weight of calcium carbonate, and 15 to 21 parts by weight of other additives.It has excellent elasticity and elongation and is excellent in durability, weather resistance, cold resistance, chemical resistance, and water resistance, making it useful as an exposure waterproofing material. It works.

As the other additives, an appropriate amount of a dispersant, an ultraviolet stabilizer, an antifoaming agent, an anti-settling agent, a water absorbent, a surfactant, and a crosslinking agent is added and used.

Alternatively, when not exposed, the coating material composition of the coating layer 30 includes 16 to 18 parts by weight of a polyurethane copolymer, 8 to 16 parts by weight of polypropylene glycol, and 12 to 20 parts by weight of dioctylphthalate (DOP, di-octyl) -A high-performance urethane coating waterproofing material consisting of phthalate), 48 to 56 parts by weight of calcium carbonate, and 5 to 10 parts by weight of other additives. It has excellent elasticity and elongation, and has excellent weather resistance, acid resistance, and chemical resistance. Exert. As the other additives, an appropriate amount of a dispersant, an antifoaming agent, an anti-settling agent, a water absorbent, a surfactant, and a crosslinking agent is added and used.

In the subsequent process, after the fourth step, it is further configured to include a fifth step of forming a degassing pipe communicating with the construction target surface (A).

As shown in FIGS. 2 and 3, the degassing pipe performs a function of collecting moisture and air generated on the lower surface of the waterproof sheet via a ventilated panel and dissipating them to the outside.
