Description

Interior and exterior finishing method of prefabricated insulation panel {.}

The present invention relates to a finishing method that is constructed on the inner and outer walls of a prefabricated building, and more particularly, after fixing the metal lath with a screw or the like on the surface of the prefabricated building material using a lightweight insulating panel, plastering or cementing the polymer cement thereon By finishing with a spray, it is possible to improve the uniformity of the existing assembly panel, and to provide a more beautiful and excellent interior and exterior wall finishing method.

In the conventional prefabricated building, a construction method that is easy to use a so-called sandwich insulation panel having a foamed styropol as a core and iron plates attached to both sides has been widely used. Such a building has become a structure that is commonly seen around these days due to the ease of construction and excellent thermal insulation. However, despite the excellent performance of these buildings, due to the monotonous finish due to the consistency of panel manufacturing, the lack of diversity and aesthetic needs of the building is becoming a factor to avoid its use. In addition, as the construction method is used, the seam treatment is poor, and often leaks into the building. Recently, in order to improve the problem of the assembled building, by using other adhesive materials on the outside of the panel to finish the construction, there are some attempts to increase the value as a building. However, in these cases, they do not meet the standard as a construction method yet, and there are many problems that can occur due to the construction as a proper know-how of the contractors. If you attach it to the outside of the iron plate without using the proper method, the external finishing materials may be dropped.

It is an object of the present invention to provide a method for completely forming a layer of cement mortar on the iron plate of a prefabricated panel in order to solve the above problems. In order to achieve the above object, there is a feature of using a method of forming a support layer between the assembly panel and the finishing mortar by using metal lath, which is a metal mesh having irregularities, and constructing polymer cement mortar thereon.

5: finish blowing

Therefore, the present invention has devised a method that can easily finish the interior and exterior walls while utilizing the characteristics of the assembly method, it is fixed to the iron plate with a screw using a metal las on the outside of the sandwich panel by installing a polymer cement mortar thereon This results in a more perfect attachment, which goes beyond the monotony of existing panels, making it an excellent building with aesthetics for waterproof rust protection and extending the durability of the building.

Referring to this method in detail, (1) in FIG. 1 is a sandwich panel, which is often a panel using expanded polystyrene or expanded polyurethane. The metal lath of (2) is fixed on it using the screw of (3). (4) is a polymer cement adhesive mortar, which is to be applied on the metal lase previously constructed. The iron plate of the panel used here is used in the form of a flat plate that does not need to bend because the outer finish is made. And the panel and the joints and the edges of the panel face each other, and the metal lath is attached on it, so it is easy to assemble without the need for other subsidiary materials. This makes construction faster and more economical. Secondly, in the construction of the metal lath, a suitable metal lath thickness of about 5 mm is appropriate, and the size of the net is 5-15 mm. If the thickness is thicker than this, adhesive mortar is used a lot and construction cost is not appropriate. If the size of the mesh is too small, the adhesion surface of the adhesive mortar is small, so the adhesive strength is weakened, so the size of the above range is appropriate. These metallass do not need to be manufactured separately and do not need special consideration because they use existing building products. Thirdly, the finishing mortar is another feature of the present method using polymer cement adhesive mortar. The adhesive mortar is coated on the metal lath to serve as a finish for the exterior. Polymer cement mortars, which are used as finishing materials, are usually classified into two types. One is a method in which a filler is contained in a polymer emulsion resin such as an acryl-based or vinyl acetate-based resin and mixed with cement to be used as an adhesive mortar. Another method is to use an adhesive mortar in which inorganic fibers, powdered polymer resin, powder waterproofing agent, inorganic pigment, etc. are added to the inorganic aggregate and mixed dry. The former is recently used in the outer wall insulation finishing method, both methods can be used in the present invention. However, in the former, raw materials are mixed with each other in the construction site, resulting in uneven mixing and quality variation depending on the conditions. Therefore, in the present invention, powdery inorganic polymer cement adhesive mortar is more preferable. Here, the adhesive mortar is not only excellent in adhesion, waterproofing, rustproofing and weather resistance, but also has a variety of choices of the final finishing material to give a natural feel to further improve the function as a building. The material of polymer cement adhesive mortar is 35-55% by weight of aggregate of 0.1-2mm size, 35-55% by weight of portland or back cement, and 2-cellulose fiber or sepiolat inorganic fiber as internal binder. 10 wt% is contained, and 3-10 wt% of resins such as acryl, ethylene-vinyl chloride-laurate, and acetate-vinyllaurate are used as powder polymer resins, and calcium stearic acid, zinc stearic acid, The metal salt powder is preferably added in the range of 0.2-1.5% by weight, and other cellulose thickeners for improving the workability in the range of 0.03-0.8% by weight. In addition, in consideration of the appearance, it may be used by mixing an inorganic pigment, loess and the like. The blended polymer adhesive mortar should be more than 10kgf / ㎠ bond strength by KS F4716. After the construction of polymer cement adhesive mortar with the above performance, various finishing materials can be used to show various exterior effects. 2 illustrates a simple construction example of the present invention in cross section, and the present invention is not limited to the construction example. In FIG. 2, (1) is a sandwich panel, which is a panel using expanded polystyrene. After constructing the panel on the steel frame, fix the metal lath of (2) using the screw of (3) on it. (4) is a polymer cement adhesive mortar, which is to be applied on the metal lase previously constructed. Process (2) to (4) on the inside and outside surfaces of the assembly panel at the same time, and in the case of the outer wall is sprayed with the additional finishing material of (5), and the inner wall is finished with wallpaper or a thin synthetic resin wall finishing material. You can do it.

Through the present invention, it is possible to finish the inorganic plaster on the outer surface of the prefabricated panel can improve the uniformity of the existing prefabricated panel, it is possible to pursue the diversity as a building with the effect of waterproof rust prevention. As an additional finish on top of this process, various polymer finishes, tiles, stone tiles, or natural granite plastering materials can be used. In addition, this method allows the interior walls to be constructed in the same way, allowing natural finish of minerals, which also has the function of fire protection. Existing heat insulation panel has a structure that is vulnerable to flame retardant by pasting the plywood or wallpaper directly on it, but by applying the method of the present invention can be made of a fireproof structure to reduce the risk of fire.
