KR-102960923-B1 - SANDWICH PANEL FOR CATTLE SHED

Abstract

The disclosed invention relates to a sandwich panel for livestock barns in which corrosion can be prevented despite a highly corrosive livestock barn environment by providing two plates, the outermost surface of which is an aluminum panel or an aluminum alloy panel, and fire damage can be minimized by laminating a flame-retardant layer having an uneven structure on the inner surface of the two plates and interposing a foam layer therebetween, and the foam layer can be effectively integrated due to the uneven structure. A sandwich panel for livestock use according to one embodiment of the disclosed content is characterized by comprising two plates formed in a square plate shape and having corrosion resistance, a flame-retardant layer formed laminated on the inner surface of each of the two plates, and a foam layer interposed between the flame-retardant layers.

Description

Sandwich panel for livestock use The disclosed content relates to a sandwich panel for livestock barns manufactured from corrosion-resistant and flame-retardant materials, which exhibits corrosion resistance in highly corrosive livestock barn environments while minimizing fire damage. Unless otherwise indicated in this specification, the contents described in this section are not prior art for the claims of this application, and are not to be recognized as prior art simply because they are included in this section. Generally, sandwich panels consist of a core material filled between a pair of metal plates. They are widely used in the construction of factories, warehouses, and livestock sheds due to their relatively low unit cost, ease of construction, and features such as thermal insulation and flame retardancy. However, livestock barns such as pig or cattle barns are constantly exposed to high humidity, and large amounts of highly corrosive ammonia gas are emitted from animal manure; therefore, conventional sandwich panels used for constructing livestock barns typically corrode within a short period due to these special environmental conditions. When corrosion occurs in sandwich panels used in livestock barns, it not only makes the exterior unsightly but also inevitably weakens their strength, leading to structural vulnerability and potentially adversely affecting the health of the livestock. For this reason, repair work involving the prompt replacement of affected sections must be carried out when corrosion develops in the sandwich panels; failure to do so can cause the corrosion to spread to the entire panel structure, necessitating the reconstruction of the barn. Furthermore, fires can occur in livestock barns due to causes such as overheating or electrical short circuits resulting from the prolonged use of various equipment, such as heaters and fans. If such a fire occurs, the barn can be completely destroyed in a short period of time due to the characteristics of sandwich panels; in this case, serious economic losses may result, including not only the cost of the barn but also the death of the livestock inside. For this reason, sandwich panels are required to be non-combustible or possess a high level of flame retardancy. FIG. 1 is a perspective view of a sandwich panel for livestock use according to one embodiment of the disclosed content. FIG. 2 is a cross-sectional view of a sandwich panel for a livestock use according to one embodiment of the disclosed content. The advantages and features of the disclosed content and the methods for achieving them will become clear by referring to the embodiments described below in detail together with the accompanying drawings. However, the disclosed content is not limited to the embodiments disclosed below but may be implemented in various different forms. These embodiments are provided merely to ensure that the disclosure of the disclosed content is complete and to fully inform those skilled in the art of the scope of the disclosed content, and the disclosed content is defined only by the scope of the claims. Throughout the specification, the same reference numerals refer to the same components. In describing the embodiments of the disclosed content, if it is determined that a detailed description of known functions or configurations could unnecessarily obscure the essence of the disclosed content, such detailed description will be omitted. Furthermore, the terms described below are defined considering the functions in the embodiments of the disclosed content, and these may vary depending on the operator's intent or convention. Therefore, their definitions should be based on the content throughout this specification. FIGS. 1 and FIGS. 2 illustrate one embodiment according to the disclosed content. FIGS. 1 is a perspective view and FIGS. 2 is a cross-sectional view. Hereinafter, the components of a sandwich panel (1) for shaft use and their operational relationships according to a preferred embodiment of the disclosed contents will be described in detail with reference to FIGS. 1 and FIGS. 2. First, a pair of side plates (10) are provided. These side plates (10) are each provided on the outermost side of the shaft sandwich panel (1), and serve to form the overall shape of the shaft sandwich panel (1) while simultaneously allowing the components to be described later to be interposed therein. These two plates (10) are formed in the shape of square plates with length in the vertical direction, but their size can be varied. It is desirable that the two plates (10) have corrosion resistance so that they can be prevented from corroding in a livestock barn environment where a large amount of corrosive gas, such as ammonia, is emitted and humidity is high. To this end, the two plates (10) are aluminum panels or aluminum alloy panels, but it goes without saying that panels made of various other materials with corrosion resistance can also be used. In particular, it is p
