Description

Waterproofing system of fabricated parking lot

The present invention relates to a waterproof construction method of a prefabricated parking lot, and to the prefabricated structure (iron plate, galvanized steel sheet, other alloy steel sheet, concrete structure) directly after the completion of the waterproof treatment in the production plant, characterized in that the assembly and the execution process in the field finish. It relates to a waterproof method.

In the parking lot waterproofing method of the prior art, after the parking lot is assembled and installed, waterproofing is performed using sheet waterproofing, urethane waterproofing, rubber, acrylic, rubber asphalt, water repellent, epoxy, and other waterproofing materials. However, there are various problems with these methods. In the case of the non-exposed waterproofing method, as shown in FIG. 1, after the completion of the waterproofing work, the mortar work should be applied to concrete and asphalt concrete, which is a post-working process. Therefore, a load is applied to the structure. As shown in FIG. 2, cracks are generated at weak areas due to repeated contraction and expansion, and adhesive strength is weakened by shrinkage at ends, resulting in curling and losing the purpose of waterproofing. In addition, it takes a lot of time to complete the work in general, and problems such as dust pollution, noise, smell, fire, etc., which are factors of civil pollution during waterproofing and water pollution work at city plants.

In the present invention, in order to solve the problem that the load is applied to the structure, the occurrence of cracks, curling phenomenon at the end, a lot of time consuming problem, environmental pollution, the problems caused by civil complaints of neighboring residents during waterproofing work, etc. As shown in the drawing, we developed a waterproofing method characterized in that the steel plate, galvanized steel sheet, other alloy steel sheet, and concrete structure, which are prefabricated structure materials, are directly waterproofed at the production plant, and then assembled and sealed at the site. In order to make the surface of the structure, in the case of steel plate, galvanized steel, other alloy steel, concrete structure, the surface was shorted, sanded, ground, and in the case of concrete structure, after sanding and grinding work 1 Liquid and two-component primers, 200-1,000 ㎛ fine silica, calcium carbonate, cement, other inorganic and oil After a mixture of water, an organic inorganic mixture mekkun the pores of the surface and invented a water treatment method characterized in that it waterproof.

The primer used in the present invention is a polyurethane resin, polyurethane-polyurea resin, polyurea resin as the main material, the joints between the structure is polyurethane, polyurethane-polyurea, polyurea, acrylic, SBR, Acrylic urethane, silicone, modified silicone, butyl rubber and polysulfide sealing materials were used.

Hereinafter, the waterproof method manufactured by the present invention will be described as an example.

Example 1

In the surface treatment of the steel plate used for the prefabricated parking lot, the surface was shorted, sanded and ground, followed by air blowing and solvent cleaning. Subsequently, the primer work was used after mixing and mixing cement in a weight ratio of 1: 1 to PLYADEK T-117 (primary of Gangnam Hwasung Co., Ltd.) as a material. (PLYADEK) PF-359 / E-145 (Gangnam Hwaseong Co., Ltd. waterproof coating material) was formed and transported and assembled to the site, and the joints between the structures and the urethane-based sealing material ksil (K) -SEAL) KC-300A / KC-330B (Sealing material of Gangnam Hwaseong Co., Ltd.) After completing the work, the problems observed after the results are shown in Table 1.

Example 2

In the surface treatment of the concrete structure used for the prefabricated parking lot, air blowing was performed after sanding and grinding work. After the completion of the plowing operation using fine silica sand to fill the voids on the surface before the primer work in the process, after confirming the curing, the attached fine silica sand was removed by brush, spatula and air blowing. In order to fill the voids that do not fill up and to improve adhesion, the mixture was used after mixing and mixing cement in a PLYADEK T-117 in a weight ratio of 1: 1. After the waterproofing film was formed using the same material and transported to the site, the assembly was completed. The result of observing the problem after completing the work by sealing with the same sealing material as [Example 1] is shown in 'Table 1'.

Example 3

After using the same iron plate as in [Example 1] and completing the same surface treatment and primer work as in [Example 1], Stella coat which is a fast curing spray coating material as a waterproof coating layer forming material ( ) KA-690 / KR-690 (Gangnam Hwaseong Co., Ltd. spray waterproofing coating material) was formed and transported and assembled to the site. Sealing with the same sealing material as [Example 1] was completed. The result of observing the problem is shown in Table 1.

Example 4

After completing the same surface treatment and primer work as in [Example 2] on the same concrete structure as in [Example 2], a waterproof coating was formed using the same material as in [Example 3], and then transported and assembled to the site. Example 1] The result of observing the problem after sealing work with the same sealing material as shown in [Table 1] is shown.

Comparative Example 1

[Example 1] After the assembly, installation and completion of the same iron plate in the parking lot, the same surface treatment process and primer treatment as in [Example 1], and after the formation of the waterproof coating film with the same material as [Example 1] and [Example 1] Table 1 shows the results of observing the problem after the work is completed by sealing with the same sealing material.

As described above, the present invention does not apply a load to the structure by forming a waterproof coating on the structure directly in the prefabricated parking lot waterproofing method of the prior art, finishing the assembly and sealing treatment work at the construction site. In addition, it is excellent in terms of economic efficiency as it can shorten the construction period. In addition, it is possible to block the occurrence of cracks in weak areas by shrinkage, expansion, and there is no problem that the end of the waterproofing is lost due to curling phenomenon occurs at the end. The environmental pollution of the construction site can be prevented in advance, and the scattering of the dust, noise, smell, fire, etc. can be prevented in advance, and the construction materials waste is concentrated in the structure production plant for easy management and parking. It can block the contamination of the assembly site.
