Description

Technical Field

[0001] The utility model relates to the technical field of cold storage insulation structures, in particular to a local lowering insulation system for interlayer floors. Background Art

[0002] Multi-layer cold storage often has the same temperature zone above and below and is used at the same time. It is necessary to do local insulation and cold bridge treatment on the floor and ceiling between layers. Conventionally, polyurethane is directly sprayed on the existing floor and ceiling to form an insulation layer. Although this insulation layer can also have a thermal insulation effect, it will cause the insulation layer and the original floor or ceiling to be at different elevations, resulting in some areas being abrupt, affecting the existing height of the floor and ceiling and the overall appearance. Utility Model Content

[0003] In order to solve the technical problems mentioned in the background technology, the utility model provides a local lowering insulation system for inter-layer floor slabs.

[0004] The utility model adopts the following technical scheme: a local lowering insulation system for inter-layer floor slabs, comprising a first settlement zone and a second settlement zone respectively embedded in adjacent upper ground and lower ceilings; a first cyanogen vapor barrier layer, a first polyurethane thermal insulation layer and a waterproof layer are sequentially laid from bottom to top in the first settlement zone; a cement mortar leveling layer is tightly laid on the upper surface of the waterproof layer; a reinforced concrete surface layer is laid on the cement mortar leveling layer; the reinforced concrete surface layer and the wall surface are sealed by a sealing paste; the height of the reinforced concrete surface layer is flush with the top of the first settlement zone; a second cyanogen vapor barrier layer, a second polyurethane thermal insulation layer and a fire retardant coating layer are sequentially laid from top to bottom in the second settlement zone; the height of the top of the second settlement zone is lower than the height of the fire retardant coating layer.

[0005] Furthermore, the depth range of the first settling zone and the second settling zone is 1500-2000 mm.

[0006] Furthermore, the first polyurethane thermal insulation layer is formed by on-site layered spraying, and its thickness ranges from 100 to 200 mm; the second polyurethane thermal insulation layer is formed by on-site layered spraying, and its thickness ranges from 100 to 200 mm.

[0007] Furthermore, the thickness of the reinforced concrete surface layer ranges from 120 to 150 mm.

[0008] Compared with the prior art, the advantages of the utility model are:

[0009] The local lowering insulation system of the interlayer floor designed by the utility model simultaneously sets a first settlement zone and a second settlement zone between adjacent ground and ceiling, arranges a first cyanide vapor barrier layer, a first polyurethane insulation layer, a waterproof layer, a cement mortar leveling layer and a reinforced concrete surface layer in the first settlement zone, and the total height is flush with the top of the first settlement zone, and arranges a second cyanide vapor barrier layer, a second polyurethane insulation layer and a fire retardant coating layer in the second settlement zone, and the overall height is not lower than the height of the second settlement zone. It can insulate at the local lowering of the plate to achieve the effect of breaking the cold bridge insulation, and does not affect the height of the original ground and ceiling, thereby improving the overall appearance of the cold storage.

DETAILED DESCRIPTION

[0013] In order to facilitate those skilled in the art to understand the technical solution of the utility model, further description is now made with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model.

[0014] In the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present invention. However, it is apparent that one or more embodiments may be implemented without these specific details. In addition, in the following description, descriptions of known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0015] like Figure 1As shown, the interlayer floor local lowering insulation system designed in this embodiment includes a first settlement area 1 and a second settlement area 2 respectively embedded in the adjacent upper ground and lower ceiling. In specific implementation, the first settlement area 1 and the second settlement area 2 are formed by local lowering around the floor, and the depth range of the first settlement area 1 and the second settlement area 2 is 1500-2000mm. The first cyanogen vapor barrier 3, the first polyurethane insulation layer 4 and the waterproof layer 5 are laid from bottom to top in the first settlement area 1. The first polyurethane insulation layer 4 is formed by on-site layered spraying, and its thickness range is 100-200mm. A cement mortar leveling layer 6 is tightly laid on the upper surface of the waterproof layer 5, and a reinforced concrete surface layer 7 is laid on the cement mortar leveling layer 6. The thickness range of the reinforced concrete surface layer 7 is 120-150mm. The reinforced concrete surface layer 7 and the wall surface are sealed by sealing paste. The height of the reinforced concrete surface layer 7 is flush with the top of the first settlement area 1. The second cyanocondensation vapor barrier layer 9, the second polyurethane insulation layer 10 and the fire retardant coating layer 8 are laid in the second settlement area 2 from top to bottom. The second polyurethane insulation layer 10 is formed by on-site layered spraying, and its thickness ranges from 100 to 200 mm. The top height of the second settlement area 2 is lower than the height of the fire retardant coating layer 8, which increases the use height of the cold storage ceiling and enhances practicality.

[0016] To sum up, the inter-layer floor local lowering insulation system designed in this embodiment sets the first settlement zone and the second settlement zone between the adjacent ground and ceiling at the same time, and arranges the first cyanide vapor barrier layer, the first polyurethane insulation layer, the waterproof layer, the cement mortar leveling layer and the reinforced concrete surface layer in the first settlement zone, and the total height is flush with the top of the first settlement zone; the second cyanide vapor barrier layer, the second polyurethane insulation layer and the fire retardant coating layer are arranged in the second settlement zone, and the overall height is not lower than the height of the second settlement zone. It can insulate at the local lowering of the floor to achieve the effect of breaking the cold bridge insulation, without affecting the height of the original ground and ceiling, thereby improving the overall appearance of the cold storage.
