Description

Steel waterproofing construction method and waterproofing system constructed by the method {Rooftop steel waterproofing method and system}

The present invention relates to a steel waterproofing construction method and a waterproofing system constructed by the same, and more specifically, to a steel waterproofing construction method and a waterproofing system constructed by the same method, and more specifically, to a steel waterproofing construction method that can be implemented simply and effectively than in the prior art, as well as excellent durability, which does not require frequent repair work It relates to a waterproofing construction method and a waterproofing system constructed by the method.

Buildings, especially those constructed of concrete, suffer from leaks and condensation due to cracks over time, which weakens durability and promotes aging. In particular, in recent years, many flat roofs are being constructed as buildings have grown in size. In the case of flat roofs, structurally, rainwater tends to collect easily, so there is a large problem in the possibility of water leakage.

Therefore, it can be said that waterproof construction is essential in order to prevent leakage of the building roof slab. In this regard, a method using an asphalt sheet is known as a waterproof construction method that is currently widely used.

Asphalt sheet is a building material in which straight asphalt and APP (Atactic Polypropylene) or SBS (Styrene Butadiene Styrene) are impregnated or coated with the core material of short fiber nonwoven fabric, stretched film, and unstretched film.

In the conventional waterproofing construction method using an asphalt sheet, as shown in FIG. 1, a primer is applied to the surface of the slab 1 to form a primer layer 2, and liquid asphalt is applied on top of the primer layer 2, After forming the asphalt layer 3, a plurality of waterproof sheets 4 integrally formed with silica sand are provided on the upper part of the asphalt layer 3 and installed at regular intervals, and between the waterproof sheet 4 and the adjacent waterproof sheet. The filling layer 5 is formed by filling the liquid asphalt.

Then, the asphalt tape 6 is attached so that the entire upper surface of the filling layer 5 and one edge of the waterproof sheet 4 are warmed, and the same as the silica sand layer of the waterproof sheet 4 on the asphalt tape 6 The construction is completed when the silica sand layer 7 is formed by spraying the silica sand at a height, and then a coating agent is applied to the top of the silica sand layer 7 to form the coating layer 8 .

However, the conventional waterproof construction method as shown in FIG. 1 has a problem in that time and manpower are wasted because the process is complicated, and when heating asphalt, heating costs occur due to the use of oil, and also environmental pollution because carbon dioxide or harmful gas is emitted. There is a high possibility that a safety accident may occur during the operation of heating equipment.

In addition, in the conventional method of treating the parapet part in waterproof construction of a roof slab, a member (cant strip) having a triangular cross section is put in the right angle part, and the waterproof sheet is extended and adhered to the parapet part, and the upper part is water There is a method of installing a protective wall after flashing, but this method has problems in that the process is complicated and frequent defects occur.

Accordingly, an alternative for solving the above problem has been disclosed in FIG. 2 . 2, the rubberized asphalt sheet 10 is installed on the slab 1 so as to be spaced apart from the parapet 9 at a predetermined distance, and the molten asphalt ( After filling 11), the rubberized asphalt tape 12 is attached to cover the lower part of the rubberized asphalt sheet 10, the molten asphalt 11 and the parapet 9, and the rubberized asphalt tape 12 and the parapet 9 A parapet treatment method of forming a waterproofing layer 13 on the pet 9 is known.

However, since this conventional parapet treatment method requires the use of molten asphalt 11 to form a waterproofing layer, separate equipment is required and handling is inconvenient, and pre-production of the rubberized asphalt tape 12 is required, so the process This is a very complex and time and manpower consuming problem.

As described above, in the case of the prior art, the waterproof performance is not good due to the method or functional limitations, and thus, it is necessary to develop a technology to compensate for this.

Since the urethane foam insulation layer 170 is made of a urethane material, it is quite advantageous in terms of load, insulation effect, construction convenience, air, construction cost, and the like. For example, the urethane foam insulation layer 170 may be configured as a panel, but the use of the panel is inefficient due to cost or the relationship with the vertical steel frames 192 and 191 .

The urethane material constituting the urethane foam insulation layer 170 may be obtained by mixing a composition comprising a main agent including polyol, a foaming agent and gelatin and a curing agent including isocyanate in a 1:1 weight ratio.
