Description

Technical Field

[0001] The utility model relates to the technical field of building thermal insulation layers, in particular to a thermal insulation layer used for a location with a drastic temperature difference change. Background Art

[0002] Building insulation layer refers to the structural layer that uses lightweight insulation materials with low thermal conductivity coefficient on the exterior walls, roofs, floors and other parts of the building to reduce the heat dissipation from the building's interior to the outside. Its function is to reduce the loss of indoor heat, maintain the indoor temperature of the building stable, and improve the building's thermal insulation performance, thereby achieving energy conservation and improving living comfort.

[0003] However, for installations in areas or locations where the temperature difference changes dramatically, the insulation layer will produce thermal expansion and contraction effects due to frequent temperature changes, which may cause cracks or falling off in the insulation layer, thus affecting its insulation effect.

[0004] Therefore, it is necessary to design a thermal insulation layer for locations with drastic temperature differences to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to provide a heat-insulating layer for a location with a drastic temperature difference change, so as to solve the problems raised in the above-mentioned background technology.

[0008] As a preferred solution of the present invention, the thickness of the inner thermal insulation layer is greater than the thickness of the first outer thermal insulation layer and the second outer thermal insulation layer, and the inner thermal insulation layer is located between the first outer thermal insulation layer and the second outer thermal insulation layer.

[0009] As a preferred solution of the utility model, the first outer thermal insulation layer, the second outer thermal insulation layer and the inner thermal insulation layer are made of thermal insulation materials with high deformation resistance, high thermal stability and high weather resistance.

[0011] As a preferred solution of the utility model, a measuring surface is provided on the heat flow meter, and the measuring surface is in close contact with the outer surface of the thermal insulation structure.

[0012] As a preferred solution of the utility model, the output end of the heat flow meter is electrically connected to a communication cable, and is communicatively connected to the control device via the communication cable.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] In the utility model, a thermal insulation layer is set up for parts with drastic temperature differences. Since the first outer thermal insulation layer, the second outer thermal insulation layer and the inner thermal insulation layer in the thermal insulation structure are made of thermal insulation materials with high deformation resistance, high thermal stability and high weather resistance, the thermal insulation structure can adapt to environmental deformation and temperature changes and is not easily affected by drastic changes in temperature differences, thereby effectively preventing cracks and falling off in the thermal insulation layer and improving the thermal insulation effect of the thermal insulation structure.

[0026] Specifically, the thickness of the inner insulation layer 5 is greater than the thickness of the first outer insulation layer 3 and the second outer insulation layer 4, and is located between the first outer insulation layer 3 and the second outer insulation layer 4; the first outer insulation layer 3, the second outer insulation layer 4 and the inner insulation layer 5 are made of insulation materials with high deformation resistance, high thermal stability and high weather resistance; so that the insulation structure 1 can adapt to the deformation and temperature changes of the environment, and is not easily affected by drastic changes in temperature differences, thereby effectively preventing the insulation layer or concrete from cracking and falling off due to temperature differences, eliminating the hidden dangers of water leakage, ensuring that the underground project is 100% water-free, there are no wet stains on the surface of the structure, and improving the insulation effect of the insulation structure.

[0027] Among them, the thermal insulation materials with high deformability, high thermal stability and high weather resistance can be flexible thermal insulation materials, inorganic thermal insulation materials or composite thermal insulation materials; for flexible thermal insulation materials, since flexible thermal insulation materials have good flexibility and weather resistance, they can adapt to the deformation and temperature changes of the building, thereby effectively preventing cracks and falling off of the thermal insulation layer. For example, rubber thermal insulation materials, polyurethane thermal insulation materials, etc.; for inorganic thermal insulation materials, inorganic thermal insulation materials have high thermal stability and weather resistance, and are not easily affected by temperature changes. At the same time, their compressive strength and flexural strength are also high, which can effectively prevent damage to the thermal insulation layer. For example, silicate thermal insulation materials, rock wool thermal insulation materials, etc.; for composite thermal insulation materials, composite thermal insulation materials are composed of a variety of materials, which can give full play to the advantages of various materials and improve the overall performance of the thermal insulation layer. For example, the composite use of flexible thermal insulation materials and inorganic thermal insulation materials can not only improve the flexibility and weather resistance of the thermal insulation layer, but also ensure that it has high compressive strength and flexural strength. The purpose of the present technical solution can be achieved by using any one or several of the above-mentioned thermal insulation materials.

[0029] Specifically, a measuring surface is provided on the heat flux meter 6, and its measuring surface is in contact with the outer surface of the thermal insulation structure 1; the output end of the heat flux meter 6 is electrically connected to the communication cable 11, and is communicatively connected to the control device 8 through the communication cable 11; by contacting the measuring surface of the heat flux meter 6 with the outer surface of the thermal insulation structure 1, the heat flux meter 6 can accurately measure the temperature difference and heat flow inside and outside the thermal insulation layer, and display the measurement data on the display screen of the control device 8, thereby evaluating the condition of the thermal insulation layer.
