Description

Steel insulation waterproof panel for construction and waterproofing method using the same

[0001] The present invention relates to a steel insulating waterproof panel for construction and a waterproofing method using the same, and more particularly, to a method for waterproofing a building using an insulating waterproof panel having an elastic coating protective film having elasticity formed on both sides of a steel panel.

[0002] In general, for waterproofing rooftops and other areas of concrete buildings, various waterproofing methods are known and used, such as mixing waterproofing powder and mortar and applying it to the floor of the building as a finishing coat, forming a pitch layer on the floor of the building and applying mortar to waterproof it, or applying waterproofing paint to the floor of the building.

[0003] However, this type of waterproofing construction has had the disadvantage that, over time, the waterproofing layer swells or bursts due to differences in elongation rates caused by seasonal changes and changes in humidity and temperature, and if moisture seeps into the concrete within the waterproofing layer, the concrete layer corrodes or oxidizes due to moisture, thereby breaking the waterproofing condition and causing water leakage as well as shortening the lifespan of the building.

[0004] Due to these issues, a technology has been proposed to waterproof building rooftops using steel waterproofing panels. However, steel waterproofing panels lack insulation, necessitating separate insulation construction. Furthermore, they are prone to leaks at joints between panels. Furthermore, because they must be installed at a certain distance from the floor, they are difficult to construct and cannot be used as flooring.

[0005] To overcome these shortcomings, Korean Patent No. 10-2286134 proposes a method of constructing a steel panel by forming a space in a steel panel, forming an interlocking portion along the edge thereof, and then forming a slit therein so that the slits are interlocked with each other during construction.

[0006] However, this waterproofing method using steel panels also had the disadvantage of not having an insulating effect and being difficult to construct because the slits had to be interlocked during construction.

[0007] The purpose of the present invention is to provide an architectural steel insulating waterproof panel and a waterproofing method using the same, which forms an elastic coating protective film having elasticity on both sides of a steel panel and performs waterproofing construction using the same, so that when performing waterproofing construction, not only joints between panels but also fixing points such as nails and pieces are sealed by the elastic coating protective film, thereby preventing leakage and providing excellent waterproofing performance, and also excellent insulation performance, soundproofing performance and durability, allowing semi-permanent use and excellent ease of construction.

[0008] Another object of the present invention is to provide a building steel insulation, soundproofing, and waterproofing panel and a waterproofing method using the same, which can also prevent the risk of fire by providing an additional sheet layer on a part or the entire surface of the elastic coating film.

[0009] A building steel insulation waterproof panel for achieving the above-mentioned purpose is characterized by including: a steel panel; an elastic coating formed on both surfaces of the steel panel and composed of an elastic material;

[0010] The upper or lower surface of the steel panel is characterized in that the elastic coating is formed on the entire surface or edge of the steel panel.

[0011] The steel panel is characterized in that an elastic coating film in the shape of the letter 'L' is formed on the edge of the upper surface, and an elastic coating film in the shape of the letter 'L' is formed on the edge of the lower surface.

[0012] The thickness of the above steel panel is 0.3 to 1.4 mm, and the thickness of the elastic coating film is characterized by being 0.3 to 15 mm on the upper side and 1 to 4 mm on the lower side.

[0013] The above steel panel is a color steel plate, and the elastic coating is characterized in that it contains as a main component at least one of raw rubber, synthetic rubber, rubber derivative, vulcanized rubber, silicone, silicone rubber, latex, and urethane.

[0014] The above elastic coating is composed of a Vinyl Acetate-Ethylene Copolymer Emulsion and is characterized by a thickness compression ratio of 10 to 70% and a compression recovery ratio of 85 to 100%.

[0015] And the waterproofing method according to the present invention is characterized by including a step of preparing a construction surface of a building, and a step of installing and fixing the steel insulating waterproofing panel on the prepared construction surface.

[0016] The architectural steel insulating waterproof panel of the present invention and the waterproofing method using the same have the advantages of not only excellent waterproofing performance, insulation performance, and soundproofing performance, but also excellent durability, allowing for semi-permanent use, a smooth construction surface, and excellent durability, allowing it to be used as a floor surface. In addition, they have the advantage of excellent convenience in construction, as no separate fixings or connectors are required.

[0026]

[0027] Hereinafter, the present invention will be described in detail.

[0028] In the past, when waterproofing was done using only steel panels, not only was there a problem with water leakage, but separate insulation and soundproofing functions were lacking, requiring separate insulation and soundproofing construction. In addition, when installing in underground parking lots, basements, rooftops, etc., the construction had to be done at a certain distance from the floor surface, which made it difficult to use as a floor surface for placing objects or walking on, etc., which made construction inconvenient.

[0029] The present invention is intended to overcome the shortcomings of such conventional steel panels, and the architectural steel insulation waterproof panel of the present invention is characterized by including: a steel panel; an elastic coating formed on both sides of the steel panel and composed of an elastic material;

[0030]

[0031] Hereinafter, the present invention will be described in detail with reference to the drawings.

[0032] As shown in FIGS. 1 and 2, the architectural steel insulation waterproof panel of the present invention comprises a steel panel (100); an elastic coating film (200) formed on both surfaces of the steel panel (100) and made of an elastic material;

[0033] The above steel panel (100) is conventionally used, and its thickness is sufficient if it is about 0.2 to 3.4 mm. Most preferably, for the purpose of external waterproofing, it is used with a thickness of 0.2 to 3.4 mm, and for the purpose of internal waterproofing, it is used with a thickness of 0.2 to 2 mm. It goes without saying that the size of the steel panel (100) in the present invention, i.e., width and length, is not limited.

[0034] In addition, the steel panel (100) may use a colored steel plate having color on one or both sides to make its appearance more attractive, but this is not limited to its implementation.

[0035] The above elastic coating (200) is a characteristic configuration of the present invention, and is formed on both surfaces of the steel panel (100). That is, the steel insulating waterproof panel of the present invention can be directly constructed on a concrete floor surface or the like by the elastic coating (200), and exhibits excellent waterproofing performance, insulating performance, soundproofing performance, and durability even without being separated by a certain distance from the construction surface.

[0036] The above elastic coating film (200) is composed of an elastic material, thereby providing a cushioning feeling to the steel insulation waterproof panel, and due to the compressive and sealing properties of the elastic coating film (200), no leakage occurs at the fixing portion and joint portion when the steel insulation waterproof panel is fixed or interconnected. In the present invention, it is preferable that the thickness compression ratio of the elastic coating film (200) is 1 to 70%, and the compression recovery ratio is 60 to 100%. If the thickness compression ratio is less than 1%, the above effect is not exerted, and if the thickness compression ratio exceeds 70% or the compression recovery ratio is less than 60%, there is a risk of leakage occurring. At this time, the thickness compression ratio and the compression recovery ratio are 0.5 kg / cm. 2 It is based on when a load is applied.

[0037] More specifically, when fixing the steel insulating waterproof panel with nails, pieces, etc., the elastic coating (200) is compressed and fixed, and the compressed elastic coating (200) has the property of recovering elasticity again, so that the fixing part is sealed, thereby preventing leakage. In addition, when the edges of the steel insulating waterproof panels are installed by overlapping and connecting them and fixed, the overlapping joint part is also fixed by compressing the elastic coating (200), so that the joint part is sealed due to the property of the elastic coating (200) to recover elasticity again, thereby preventing leakage. Accordingly, the steel insulating waterproof panel of the present invention has the advantage of excellent convenience in construction because separate fixings or joint waterproofing materials are unnecessary, and construction such as fitting a slit formed in a conventional steel plate is also unnecessary.

[0038] At this time, if the elastic coating film (200) is composed of an elastic material, the specific material thereof is not limited, but it is preferably composed of at least one of known raw rubber, synthetic rubber, rubber derivative, vulcanized rubber, silicone, silicone rubber, latex, and urethane. This also takes durability into consideration. In addition, in the present invention, when the elasticity of a material having no elasticity at all is defined as '0', the elastic material may include all materials having an elasticity of 0 or higher.

[0039] Most preferably, the elastic coating film (200) is formed of Vinyl Acetate-Ethylene Copolymer Emulsion (VAE; CAS No. 24937-78-8). This is because the Vinyl Acetate-Ethylene Copolymer Emulsion not only has excellent elasticity and elastic recovery, but also has excellent physical properties such as overall strength and hardness. In addition, it forms a fine coating film and has waterproofing properties, so it is the most preferable material in the present invention.

[0040] For example, the elastic coating film (200) can be formed by mixing a main part including 100 parts by weight of an isocyanate-terminated prepolymer, 1 to 10 parts by weight of zinc chromite, and 1 to 10 parts by weight of nano-type ceramic balls composed of aluminum silicate, and a hardener part including 100 parts by weight of polyetheramine, 5 to 30 parts by weight of polyaspartic ester, and 5 to 15 parts by weight of a chain extender such as a diamine monomer, at a weight ratio of 1:0.5 to 1, and then applying the mixture.

[0041] In addition, the elastic coating film (200) may be a transparent material or a colored material mixed with pigment, but this is not limited thereto.

[0042] The above elastic coating (200) also has an insulating function. It is made of a material with significantly lower thermal conductivity than the steel panel (100), so it has excellent heat insulation properties. The elastic coating (200) formed on the upper surface of the steel panel (100) primarily blocks heat, and the elastic coating (200) formed on the lower surface of the steel panel (100) secondarily blocks heat, thereby exhibiting an excellent insulating effect.

[0043] In addition, the elastic coating film (200) also exhibits a soundproofing function. The elastic coating film (200) formed on the upper surface primarily blocks sound, and the elastic coating film (200) formed on the lower surface secondarily blocks sound, thereby exhibiting an excellent soundproofing effect.

[0044] The above elastic coating (200) is a fine coating and also has a waterproofing effect.

[0045] In the present invention, the thickness of the elastic coating film (200) is preferably 0.3 to 30 mm on the upper side and 0.3 to 30 mm on the lower side, taking into consideration waterproofing, insulation, and soundproofing due to compression of the fixing and connecting portions.

[0046]

[0047] Meanwhile, the elastic coating film (200) may be formed over the entire upper and lower surfaces of the steel panel (100), as shown in FIGS. 1 and 2, or, considering the connection and installation between steel insulating waterproof panels, the elastic coating film (200) may be formed over a part or the entire edge of the steel panel (100), as shown in FIGS. 3 and 4, on the upper or lower surface of the steel panel (100).

[0048] That is, by forming an elastic coating (200) only at the joints and fixed parts, the sealing force is increased, and water leakage is blocked to increase the waterproof performance.

[0049] For example, an elastic coating film (200) may be formed over the entire edges of the upper and lower surfaces of the steel panel (100). In addition, as shown in FIGS. 3 and 4, an elastic coating film (200) in the shape of the letter 'L' is formed on the edge of the upper surface of the steel panel (100), and an elastic coating film (200) in the shape of the letter 'L' is formed on the edge of the lower surface of the steel panel (100). When connecting and installing steel insulating waterproof panels as shown in FIG. 5, an elastic coating film (200) is formed on the edge of the upper surface of one of the neighboring panels, and an elastic coating film (200) is formed on the edge of the lower surface of the other panel, thereby improving the flatness of the construction surface while also providing excellent sealing power, thereby improving the waterproofing performance. At this time, it is natural to fix the joint portion with a tacker or nail, and the illustration thereof is omitted.

[0050] Alternatively, as shown in FIGS. 6 and 7, an elastic coating film (200) in the shape of the letter '⊂' is formed on the edge of the upper surface of the steel panel (100), and an elastic coating film (200) in the shape of the letter '⊃' is formed on the edge of the lower surface of the steel panel (100), so that when connecting and installing steel insulation, soundproofing, and waterproof panels as shown in FIG. 5, an elastic coating film (200) is formed on the edge of the upper surface of one panel among the neighboring panels, and an elastic coating film (200) is formed on the edge of the lower surface of the other panel, thereby improving the flatness of the construction surface while also providing excellent sealing power, thereby improving the waterproofing performance. At this time, it is natural to fix the joint portion with a tack or nail, and its illustration is omitted.

[0051] In addition, in the present invention, for the convenience of explanation, the steel panel (100) is described as having a flat shape, but if necessary, the steel panel (100) may have a three-dimensional shape with a curved surface, or a shape with a bent portion due to a bent edge, and the elastic coating film (200) may be formed with the same thickness throughout to correspond to the shape of the steel panel (100), and the deformation thereof is not limited.

[0052]

[0053] Meanwhile, as shown in Fig. 8, the steel insulation soundproofing waterproof panel of the present invention may additionally have a sheet layer (300) formed on both or one of the elastic coating films (200) formed on both surfaces, which is composed of an adhesive layer (310) and a release paper (320) for protecting the adhesive layer (310).

[0054] When the above sheet layer (300) is additionally formed, construction can be performed by removing the release paper (320), so not only is the convenience of construction increased, but double waterproofing can also be easily performed.

[0055] When constructing a double waterproofing, as shown in Fig. 9, a steel insulation soundproofing waterproof panel having a sheet layer (300) formed on an elastic coating film (200) on the upper surface is constructed on the construction surface, and after removing the release paper (320) of the sheet layer (300), only the steel panel (100) is constructed, or a steel panel (100) having an elastic coating film (200) formed only on the lower surface is constructed, thereby improving waterproofing, soundproofing, durability, etc., and preventing the elastic coating film (200) from being exposed to the outside, thereby preventing fire from spreading to the steel insulation soundproofing waterproof panel in the event of a fire.

[0056] This is to enable double waterproofing construction as shown in Fig. 9, and after constructing a steel insulation soundproofing waterproof panel with a sheet layer (300) formed on the construction surface, the release paper (320) of the sheet layer (300) is removed, and the steel insulation soundproofing waterproof panel can be easily constructed again.

[0057] At this time, the type of the adhesive layer (310) is not limited, and any type used in a conventional panel is sufficient.

[0058]

[0059] The architectural steel insulation waterproof panel of the present invention, configured as described above, has the advantages of excellent waterproofing performance, insulation performance, and soundproofing performance, as well as excellent ease of construction, as described above.

[0060] In addition, the architectural steel insulation waterproof panel of the present invention can be used in all buildings and places for the purpose of waterproofing, and can be mainly used for external waterproofing such as rooftops, roofs, factory roofs, apartment roofs, apartment exterior walls, building exterior walls, and basement waterproofing, but can also be used for the interior walls of buildings, basements of buildings, and parking lots, and can also be utilized for the inside, outside, and inside bathrooms of swimming pools. In addition, when constructing a new building, it can be constructed for the purpose of preventing radon radiation and waterproofing even after the basement berm work and before the cement pouring.

[0061] When constructed on the exterior walls of buildings, brick and wood construction is possible after construction. However, if brick or wood construction is performed alone, water leakage problems may occur. However, if the waterproofing construction of the present invention is added, water leakage problems can be prevented. In addition, when constructed on the exterior walls of buildings, basements, etc., it provides excellent insulation and can completely block moisture, and can also be constructed for the purpose of finishing waterproofing wood to block moisture and waterproof it.

[0062]

[0063] Hereinafter, a waterproofing method using a steel insulating waterproof panel according to the present invention will be described.

[0064] The waterproofing method according to the present invention is characterized by including a step of preparing a construction surface of a building, and a step of installing and fixing the steel insulating waterproofing panel on the prepared construction surface.

[0065]

[0066] First, the construction surface requiring waterproofing is prepared and dust, moisture, etc. are removed. However, since the present invention utilizes panels, construction can be carried out without removing dust, moisture, etc.

[0067] As explained above, the present invention can be applied not only to rooftop floors, but also to interior and exterior walls of buildings, basements, restrooms, and sports facilities. It can be a newly constructed surface, or a floor surface on which a waterproofing film or waterproofing sheet has been applied, or on which the applied waterproofing film or waterproofing sheet has peeled off or worn away. In this case, if the waterproofing film or waterproofing sheet has already been applied, the film can be removed using a film remover, or the previously applied waterproofing sheet can be removed, or the work can be done as is without removing it.

[0068] In addition, the construction surface may be made of not only concrete but also wood, steel, etc., and there is no limitation on the material of the construction surface.

[0069]

[0070] Next, a steel insulation waterproof panel is installed on the cleaned construction surface. Since the steel insulation waterproof panel has an elastic coating (200) formed thereon, there is no need to install it at a certain distance from the construction surface. Therefore, it is installed so that the lower surface of the steel insulation waterproof panel is in direct contact with the construction surface, and is fixed to the construction surface using pieces, nails, etc. The present invention has the advantage of excellent convenience in construction because no separate fixing or connecting device is required except for the pieces, nails, etc., and the construction period is short, so that construction costs can be reduced.

[0071] In addition, if the construction surface is not flat and has a bent or curved shape, it is possible to construct by modifying the shape of the steel insulation waterproof panel, and it is also possible to manufacture and construct a steel insulation waterproof panel of a modified shape.

[0072] At this time, it is sufficient to install the steel insulation waterproof panels so that they overlap with a certain width and then fix them, but this is not limited, and it is of course possible to use the conventional joint connection method.

[0073] In addition, the present invention does not require any special construction because the joint portion is completely sealed, but if necessary, the joint portion and fixing portions such as nails and tackers may be additionally constructed using silicone or the like.

[0074] Additionally, cement and adhesive can be mixed to form an additional mortar waterproofing layer as needed, in which case it can also be used for outdoor gardens, etc.

[0075] In addition, as described above, since the shape of the steel panel (100) is not limited, it can be manufactured and used in a roof shape, tile shape, zinc shape, etc., and the construction method is sufficient as long as it is constructed in a manner suitable for the purpose of waterproofing by a conventional method.

[0076] The above method allows for installation and fixation directly against the building's construction surface, without leaving gaps, resulting in superior stability. This allows for semi-permanent use without detachment of the steel insulation and waterproof panels, even in windy areas. Furthermore, it offers the advantages of being easily constructed and cost-effective.

[0077]

[0078] As such, the present invention is not limited to the described embodiments, and it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention. Accordingly, such modifications or variations should fall within the scope of the claims of the present invention.
