Description

Technical Field

[0001] The utility model relates to the technical field of cold storage, in particular to a cold storage shear wall insulation structure. Background Art

[0002] Shear wall structures are often seen in the structural design of cold storage. Shear walls are mostly designed around the cold storage, with a small distance from the outer wall or close to the outer wall, and most of the design distances are 200mm to 550mm. If the distance between the shear wall and the outer wall is greater than 300mm, the wall insulation can be formed by directly spraying polyurethane foam to form an insulation layer structure; but if the distance between the shear wall and the outer wall is less than 300mm, due to the thin thickness of the insulation layer formed by natural foaming, some areas are prone to uneven spraying to form hollows, and the insulation and moisture-proof performance will also decrease. Therefore, it is urgent to design an insulation structure suitable for the distance between the shear wall and the outer wall less than 300mm to improve the overall insulation and moisture-proof effect of the shear wall. Utility Model Content

[0003] In order to solve the technical problems mentioned in the background technology, the utility model provides a cold storage shear wall insulation structure.

[0004] The utility model adopts the following technical scheme: a cold storage shear wall insulation structure, which is arranged between the cold storage shear wall and the outer wall, and includes a cyanogen vapor barrier layer tightly attached to the outer wall of the cold storage shear wall; the thickness of the cyanogen vapor barrier layer is 0.3-0.5mm; a plurality of layers of extruded boards are staggeredly attached to the outside of the cyanogen vapor barrier layer, and polyurethane filling blocks are arranged in the gaps between the two extruded boards; the outer wall of the extruded board is formed into a tightly attached polyurethane insulation layer by on-site layered spraying; the outer wall of the polyurethane insulation layer is tightly attached to a self-adhesive aluminum foil vapor barrier film; the thickness of the self-adhesive aluminum foil vapor barrier film is 0.4-0.6mm; a mortar leveling layer is arranged on the outer wall of the self-adhesive aluminum foil vapor barrier film.

[0005] Furthermore, the distance between the shear wall and the exterior wall is between 250-350 mm.

[0006] Furthermore, the thickness of the several layers of extruded boards ranges from 50 to 100 mm.

[0007] Furthermore, the polyurethane insulation layer has a thickness of 200-250 mm.

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

[0009] The cold storage shear wall insulation structure designed by the utility model abandons the single polyurethane layer structure by closely attaching the cyanocondensation vapor barrier layer, extruded board, polyurethane insulation layer, self-adhesive aluminum foil vapor barrier film and mortar leveling layer in sequence between the cold storage shear wall and the outer wall. The extruded board layers are attached with staggered seams, and polyurethane filling blocks are arranged in the gaps to form better insulation and moisture-proof effects. The double-layer clamping of the polyurethane insulation layer by the cyanocondensation vapor barrier layer and the self-adhesive aluminum foil vapor barrier film further improves the heat insulation and moisture-proof performance of the insulation structure, and is particularly suitable for applications where the distance between the shear wall and the outer wall is less than 300 mm.
