Detailed ways

In order to enable those skilled in the art to better understand the scheme of the utility model, and to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the utility model will be further described in detail below in conjunction with the embodiments and accompanying drawings illustrate.

As shown in Figure 1, the utility model provides a light-weight heat-insulating refractory castable layer, which is laid on the top floor of a building for thermal insulation, and includes a load-bearing layer 2 and an adhesive layer 12 formed by integral casting. The load-bearing layer 2 includes a first layer 4, a second layer 6, and an insulating block 8 sandwiched between them. The adhesive layer 12 is preferably mortar, which is used to lift the first layer 4. The second layer body 6 and the insulation block 8 are poured into a whole. The insulation block 8 of the utility model preferably adopts a cuboid structure made of aluminum silicate fiberboard or gypsum board, which are respectively connected with the first layer, 4 and the second layer 6. Both contact surfaces are provided with folds 14, and the folds 14 increase the contact area and improve the heat insulation effect. When the thermal insulation block 8 of the utility model adopts aluminum silicate fiberboard, the thermal conductivity of the aluminum silicate fiberboard is 0.14W/ m.K～0.17W/m.K, low thermal conductivity, the maximum operating temperature is 1250°C; when the insulation block 8 is made of gypsum board, 20% of the weight of the gypsum board core is crystal water, and the crystal water first decomposes and vaporizes in case of fire, consuming a lot of heat. When the temperature continues to rise, the gypsum in the board core will dehydrate and harden, which can prevent the transfer of heat source and have the function of fire prevention. The utility model carries out the heat insulation and heat preservation of the center of the wall by interposing the heat preservation block 8 between the two load-bearing layers, abandons the traditional heat insulation of the inside and outside of the wall, has low thermal conductivity, and has the characteristics of fire prevention and durable use.
