Description

Technical Field

[0001] The utility model belongs to the technical field of building decoration materials, relates to a floor wall panel, and in particular to a multi-layer composite reinforced self-insulating floor wall panel. Background Art

[0002] my country's urban population is highly dense, and residential buildings are mainly multi-story and high-rise. The sound insulation effect of residential floor slabs is poor, especially the absorption of impact sound is a long-standing problem that has not been effectively solved, which seriously affects people's quality of life. In addition, for non-heating areas, the heating and cooling effects are generally achieved through intermittent operation of air conditioners. However, most residential floor slabs do not have a lightweight insulation layer. In many cases, the residents on the upper and lower floors do not turn on the air conditioners at the same time. When the air conditioners are intermittently running, heat is easily lost through the floor slabs.

[0003] At present, there are some problems in optimizing and improving the structure and performance of lightweight insulation layer in urban residential building slabs. In order to meet the requirements of the "Energy-saving Design Standard for Residential Buildings in Hot Summer and Cold Winter Areas (JGJ134-2010)" and "Thermal Environment and Energy-saving Design Standard for Residential Buildings in Jiangsu Province (DGJ32 / J71-2014)" on the heat transfer coefficient of residential floor slabs, it is necessary to add a lightweight insulation layer to the floor slab for lightweight insulation measures. Most of them will use polystyrene lightweight insulation board on reinforced concrete, and then lay lime mortar on the polystyrene board to level the floor. Since the lime mortar is poured on the surface of the lightweight insulation board, if the seam is not cut in time or the position is incorrect, cracks are very likely to appear in areas such as door edges and column corners.

[0004] In view of the current requirements for energy conservation in buildings, it is also necessary to avoid the serious homogeneity of wood flooring products, upgrade products, and give products more functionality. Multi-layer composite reinforced self-insulating floor and wall panels have both lightweight insulation performance and performance, which can effectively reduce the impact of heat loss between floors and create a healthy, quiet and comfortable indoor environment for consumers. At the same time, it solves a series of problems in lightweight insulation in current buildings, and adopts lightweight insulation functional floor and wall material panels, so that the floor and wall panels not only have the function of decoration, but also have lightweight insulation and other functions. In addition, the use of special lightweight insulation function panels can save the load-bearing of the household floor slabs, which is safer, while saving social resources, protecting the social environment. Summary of the invention

[0005] Aiming at the problems existing in optimizing and improving the structure of the lightweight insulation layer and the lightweight insulation performance of urban residential building slabs, the utility model aims to disclose a multi-layer composite reinforced self-insulating floor wall panel.

[0009] In the preferred disclosed examples of the utility model, the phase change thermal insulation material is any one or more of paraffin, expanded perlite, crystalline hydrated salt, etc., which can be sieved and melt to store heat when heated and solidify to release heat when cooled.

[0010] In a preferred disclosed example of the utility model, the heat-insulating layer is placed between the front panel and the back panel, the distance between the front panel and the back panel is 1 to 1.5 mm, and the two are fixed with buckles.

[0011] In the preferred disclosed examples of the utility model, the density board A and the density board B have a thickness of 1 to 3 mm, preferably 2 mm, a density of 850 to 1400 g / m³, and a water absorption thickness expansion rate of ≤5%.
