Description

Rubber asphalted laminate layer waterproofing materials with root barrier for the green roof and artificial foundation and its application method}

The present invention relates to a rubber asphalt laminated waterproofing material having a waterproof layer applied for landscaping greening of a building roof and artificial ground, and a construction method thereof. More specifically, the rubber asphalt coating waterproofing material and stretch asphalt felt and felt sheet are alternately continuous After forming the waterproof layer by laying the waterproof sheet on top of the waterproof layer, the waterproof roof and concrete slab layer by planting tree roots during landscape greening are reliably waterproofed on the building roof or artificial ground that needs greening. The present invention relates to a rubber asphalt laminate waterproofing material having a waterproof layer for roofing and artificial ground greening, which can prevent breakage and excellently implement a load resistance against soil and tree planting loads, and a construction method thereof.

Rapid urbanization and industrialization have hardly found any natural ground in the city, and are covered with gray concrete and asphalt, resulting in almost no green space and declining urban environment. Since the absence of such green spaces causes environmental pollution in cities, it is urgently needed to secure green spaces that can solve the environmental problems. Recently, the rooftop greening system has been actively promoted as part of the greening of urban areas in Korea, and the demand for roofing greening and greening of artificial ground is gradually increasing thanks to the active support policies of the government and local governments. .

The concept of roof recording can be thought of as greening on the roof of a building, but more broadly the concept of greening not only the building roof but also the space above the underground parking lot, the cover of the sewage treatment plant, the cover of the underground facilities, etc. It can be seen as. Greening the artificial ground and the rooftop provides a space for living things by introducing natural elements into the urban environment along with the use of artificial land to secure insufficient green space in urban areas. Demonstrate public functions and roles, such as promoting and securing leisure space.

The advantage of green roofing of buildings is that it can save energy because it shows great effect in terms of heat insulation and insulation on the top floor, and improves the urban landscape through greening and absorbs air pollutants such as carbon dioxide and sulfur dioxide. Reduction of air pollution can be realized by supplying oxygen through it, and the natural ecosystem can be restored by seeking symbiosis with small birds or insects. In addition, there are many advantages such as humidity control, urban heat island phenomenon reduction, and urban noise reduction effect due to absorption of sound wavelength of the rooftop soil layer.

This is a reliable waterproofing work for concrete slab floors. If the waterproofing work is not carried out properly, the growing soil layer of the planting base is always kept in a wet state, so the deterioration of the waterproofing layer is severe and there is a high risk of damage of the waterproofing layer. Will receive.

Asphalt 3-ply 8-layer waterproofing is widely known as a traditional waterproofing method for roofs and artificial ground of buildings. This method is mainly based on the blown asphalt (solid blow asphalt), asphalt roofing, asphalt felt obtained during the refining process of crude oil, the asphalt primer is applied once, the molten asphalt is heated and melted at a high temperature (220 ~ 250) By applying four times, asphalt roofing two times, asphalt felt laying one by one alternately to perform a laminate (8 layers) construction is excellent in safety and reliability of waterproof. On the other hand, the method has a disadvantage that the odor due to high temperature heat melting of the asphalt and the environmental pollution caused by the smoke generation is present, the use frequency is low.

On the other hand, the general rooftop recording system applied to the green roof of the building and artificial ground is divided into a structural part and a planting base as shown in FIG. The structural part is made of a waterproof layer including a structure (concrete slab) and a heat insulating layer (not shown), and the planting base part is composed of a root barrier layer, a drainage layer, a soil filtration layer, and a growing soil layer.

In the case of the structural department, research has been conducted in various fields for a long time, and it can be seen that the performance of each component layer is relatively well organized. In the case of the planting base, research and development has been conducted mainly in the landscaping field, so the main area of interest is that it tends to be biased to the vegetation environment, such as plants and soils. There was a point that was dealt with. As a result, damages to structural parts caused by plant roots (breakage of the waterproofing layer, cracking of the concrete slab layer, etc.), which were not much of an issue at the beginning of the roof gardening, were gradually visualized. .

During the roof greening, the growing soil layer in the planting base always maintains the wet conditions. As a result, the deterioration acceleration of the waterproof layer is inevitably severe, and there is a risk of damage of the waterproof layer, and the safety and durability of the structural part are greatly affected by the damage of the waterproof layer.

In order to stabilize the rooftop greening, planting foundations (rooting layer, drainage layer, soil filtration layer, growing soil layer) must be completely constructed so as not to affect the stability and durability of structural parts (concrete slab layer, heat insulation layer, waterproof layer). However, the above-mentioned complete planting base construction may be referred to as the formation of a root barrier layer to protect the waterproofing layer that is basically constructed on the upper part of the building roof from the planting foundation.

The fundamental reason for installing the root layer is to prevent the rooting of the plant roots planted in the planting base. The growth of plant roots is very vigorous and penetrates the waterproof layer, and even the structure, that is, the case of the concrete structure, is generated, which acts as a major factor to shorten the life of the structure due to the crack of the structure.

Currently, in Korea, the development of rooting sheets is short, and the development of rooting sheets or rooting plates based on materials that are impossible to penetrate roots. The research on the development of the weatherproof material includes the weatherproof layer using copper plate material, the formation of the weatherproof layer by a soft FRP coating film, the composite sheet waterproofing material in which vinyl chloride and polyester fabric are bonded, and the waterproofing sheet using EPDM sheet. In general, the low molecular weight waterproof layer such as asphalt, the root of the plant penetrates, it is found that the root of the plant does not penetrate in the case of the rooting material combined with a certain polymer. However, such a waterproof sheet is welded, hot melt or adhesively bonded to the joints between sheets during construction, and the work is dependent on the manpower, so that the roots penetrate into the unbonded areas due to the careless construction. May appear. In other words, even if the use of a high-molecular hard sheet of the polymer having excellent root resistance, the root of the plant is penetrated into the gap of the connecting sheet of the connecting sheet of the root sheet or damaged during the installation of the sheet.

The applicant of the present application cited the waterproof safety and reliability of the conventional asphalt 3-ply 8-layer waterproofing method in order to solve the above problems, and improves the problem of environmental pollution, rubber asphalt laminated waterproofing method that can be installed at room temperature R & D completed.

Accordingly, a first object of the present invention is to alternately continuously laminate a rubber asphalt coating waterproofing material, a stretch asphalt felt and an asphalt felt sheet mainly composed of a quick-drying asphalt compound and a synthetic polymer resin adhesive, The top layer is secured by laminating a waterproof sheet that protects the waterproof layer and the slab structure from the plant roots so that moisture from the soil layer and the roots of the vegetation material do not reach the waterproof layer of the structure.

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

Rubber asphalt laminate waterproofing material having a waterproof layer for roofing and artificial ground greening and its construction method according to the present invention through the waterproof layer while safely and reliably perform waterproofing of concrete slabs which must be accompanied to create a green space. It is implemented to prevent the deterioration of the waterproofing layer by blocking the source and the roots of the vegetation material from reaching the waterproofing layer of the structure.

Figure 2 is a cross-sectional view showing an embodiment of a rubber asphalt laminated waterproofing material having a waterproof layer for roofing and artificial ground greening according to the present invention.

As shown in the drawings, the present invention is made of a quick-drying asphalt compound (Quick Drying Asphalt Compound) as a main raw material, synthetic rubber adhesive as an asphalt modifier to the fast-drying asphalt compound, synthetic polymer resin adhesive as an adhesive reinforcing agent, natural mineral fillers, etc. A first rubber asphalt coating film waterproofing layer manufactured by adding and mixing the first rubber asphalt coating layer and combined with the base surface or the primer layer of the concrete structure; A stretch asphalt felt layer laminated on an upper surface of the first rubber asphalt coating waterproofing layer and having a polyester nonwoven fabric impregnated with asphalt to reinforce tensile performance and crack resistance; A second rubber asphalt coating waterproofing layer formed of the same structure as the first rubber asphalt coating waterproofing layer and applied to an upper portion of the stretch asphalt felt layer; An asphalt felt sheet layer manufactured by coating a rubber asphalt compound on a lower surface of the stretch asphalt felt and stacked on top of the second rubber asphalt coating waterproofing layer; And it is laminated on top of the asphalt felt sheet layer and includes a rootproof sheet layer to prevent the root of the vegetation material from penetrating into the waterproof layer.

Here, the first and second rubber asphalt coating film waterproofing layers have a function of an adhesive as well as a coating film, and are cured in a dry touch state exhibiting elasticity within 1 to 2 hours after application.

In the above embodiment, the basic conditions of the first and second rubber asphalt coating waterproofing layers to impart a waterproof film are applied to the concrete base surface to increase adhesion to the concrete base surface, and the bonding strength between the concrete base surface and the stretch asphalt felt layer. It should play a role in increasing.

In the first light second rubber asphalt coating waterproofing layer of the present invention, 60 to 80 wt% of a quick dry asphalt compound (Quick Drying Asphalt Compound) as a main raw material, 5 to 15 wt% synthetic rubber adhesive as an asphalt modifier to the material, synthetic polymer as an adhesive strengthening agent 5 ~ 10wt% of resin adhesive, 5 ~ 15wt% of natural mineral fillers, 3 ~ 5wt% of natural cellulose fiber, and 0.5 ~ 1wt% of functional additives such as other dispersants and antioxidants. .

The fast-drying asphalt compound is one selected from straight run asphalt (Straight Run Asphalt), blown asphalt (Blown Asphalt) or asphalt compound mixed with straight run asphalt and blown asphalt, the mixing ratio between asphalt and petroleum solvent is asphalt compound 65 ~ 85wt%: It consists of 15 ~ 35wt% of petroleum solvent.

Asphalt is solid at room temperature. Therefore, when synthetic rubber, synthetic polymer resin adhesive and mineral fillers are added to the asphalt at room temperature, the asphalt and the petroleum solvent are mixed to form a liquid form in order to improve the mixing property.

When the mixing ratio of the petroleum solvent is less than 15% by weight in the mixing ratio between the asphalt and the petroleum solvent, it is difficult to secure homogeneity due to the high viscosity of the asphalt compound and the incompatibility with the isobutylene-based rubber or inorganic fillers. At this time, the asphalt compound viscosity is diminished, so that the mixing property is good, but it is difficult to secure the thickness of the rubber asphalt coating waterproofing layer.

The synthetic rubber is mixed with an isobutylene-based material selected from isobutylene-based rubber, polyisobutylene-based rubber or isobutylene-based rubber and a mixture of polyisobutylene-based rubber in a predetermined ratio, wherein the material and petroleum The mixing ratio between the solvents is preferably 25 to 35% by weight: 65 to 75% by weight.

The isobutylene-based rubber is formed in a solid state, and since the petroleum solvent of the fast-drying asphalt compound has low solubility in mixing with the asphalt compound, the mixing ratio is suggested as described above. That is, when the sobutylene-based rubber is less than 25% by weight, there is a problem in that the mixing property is good but the content of the petroleum solvent is large, so that the viscosity of the asphalt compound is thin so that the thickness of the waterproofing layer is not secured. In addition, when the content is 35% by weight or more, the asphalt compound may have poor compatibility with other raw materials. The petroleum solvent mixed with isobutylene rubber or polyisobutylene rubber is preferably an aromatic hydrocarbon petroleum solvent.

The synthetic rubber adhesive is intended to impart coping with heat and heat resistance and adhesion to the concrete base surface, and when the mixing ratio of the synthetic rubber adhesive is less than 5% by weight, the elongation and adhesive strength are reduced, and 15% by weight. In the case of the above addition, the elongation rate is too large, and there is a concern that the adhesive strength may be lowered, and the manufacturing cost is increased, thereby having no economic feasibility.

The synthetic polymer resin adhesive is to reinforce adhesive strength and to reinforce tensile strength and heat resistance, and mix urea resin or rosin dissolved in petroleum solvent, wherein the mixing ratio between urea resin or rosin and petroleum solvent is 25 to 35 weight. %: 65-75 weight% is preferable.

Urea resin is a solid granule at room temperature, and urea resin or rosin alone cannot be uniformly mixed with fast-drying asphalt compound, so petroleum solvent is mixed. When the ratio of urea resin and petroleum solvent is less than 25% by weight of the urea resin, the coating waterproofing material has a weak initial adhesiveness to the concrete surface, and when the urea resin is 35% by weight or more, There is a problem that the coating waterproofing material does not correspond to the concrete crack and cracks occur. Petroleum solvents mixed with urea resins or rosin are preferably aromatic hydrocarbon-based petroleum solvents.

The synthetic polymer adhesive is to reinforce the adhesive strength and to reinforce the tensile strength and heat resistance, the tensile strength and adhesive strength is weakened when added to less than 5% by weight of the blending ratio of this component, the strength is increased when added to more than 10% by weight There is a problem that cursor cracks are likely to occur.

Solvent or aromatic solvent may be used as the petroleum solvent used in the production of the asphalt compound, synthetic rubber adhesive, synthetic polymer adhesive.

The natural mineral filler is to be mixed with the synthetic rubber adhesive to give a crack resistance and to increase the adhesive strength, if less than 5% by weight of the mixing ratio of the natural mineral filler required in one application It is difficult to form the coating film, and if it is added at 15% by weight or more, there is a problem that the crack occurs in the coating film waterproofing layer and the waterproof performance is lowered.

The natural mineral filler is used in the form of haemulite (sepiolite), wollastonite, calcium carbonate, silica sand, etc., pulp fiber is used as the natural cellulose fibers.

The asphalt felt sheet (Asphalt Felt sheet) is a stretch asphalt felt reinforced with tensile performance and crack resistance by impregnating a polyester nonwoven fabric on asphalt as an upper surface, rubber asphalt compound of a predetermined thickness on the lower surface of the stretch asphalt felt It is made of a structure coated with.

In an embodiment of the present invention, the rubber asphalt compound presents a structure in which SBS (Styrene Butadiene Styrene) rubber is mixed with asphalt. In addition, the thickness of the rubber asphalt compound is approximately 1 to 3 mm. In addition, one selected from a polyester nonwoven fabric (PET nonwoven fabric), a polypropylene nonwoven fabric (PP nonwoven fabric), or a release film is attached to the lower surface of the rubber asphalt compound layer. When the lowermost surface of the asphalt felt sheet is made of polyester nonwoven fabric, a mass per unit area of 40 to 60 g / m 2 is used.

Stretch asphalt felt of the upper surface of the asphalt felt sheet is manufactured by impregnating the polyester non-woven fabric in asphalt, prevents penetration of moisture and water, and has excellent durability to implement another waterproof function on the upper surface of the asphalt felt sheet.

The stretch asphalt felt is used by impregnating a polyester nonwoven fabric in asphalt to reinforce tensile performance and crack resistance. In addition, as shown in Fig. 5, the stretch asphalt felt has an overlap lap line indicating the overlapping portion between the felt and the felt, and when the felt is laid on the coating waterproofing material, the overlapping portion of the felt is constructed. I can do it precisely.

Polyester nonwoven fabric used in the asphalt felt sheet and stretch asphalt felt (Stretchy Asphalt Felt) is used in the 70 ~ 140g / ㎡ per unit area, preferably to use 100g / ㎡ per unit area.

The stretch asphalt felt and the asphalt felt sheet presented above are usually manufactured in roll form so as to be easily laid on the rubber asphalt coating waterproof layer.
