Cold storage sandwich panel

Abstract

The invention provides a cold storage sandwich panel which is formed by splitting at least two cold storage sandwich panel units, wherein each cold storage sandwich panel unit comprises an upper plate, a lower plate and a rigid polyurethane foam layer; inserting bulges are arranged at the positions at the end face of one sides of the upper plate and the lower plate and close to the edges; small concave grooves are arranged at the outer sides of the inserting bulges; inserting concave grooves in match with the inserting bulges are arranged at the other one sides of the upper plate and the lower plate; small pit grooves are arranged at the bottoms of the inserting concave grooves; after adjacent cold sandwich panel units are inserted, the inserting bulges are in match with the inserting concave grooves; the external convex edges of the inserting concave grooves are matched with the small concave grooves at the outer sides of the inserting bulges; hollow chambers in shape of a Chinese character 'Tu (convex)' are formed between the bottoms of the inserting concave grooves and the tops of the inserting bulges; the hollow chambers are full of sealing glue, and then form glue tapes in shape of a Chinese character 'Tu (convex)' after the sealing glue is condensed; reversed H-shaped hollow chambers are formed between the external convex edges of the inserting concave grooves and the small concave grooves at the outer sides of the inserting bulges; and the reversed H-shaped hollow chambers are full of sealing glue, and then form reversed H-shaped glue tapes after the sealing glue is condensed. The cold storage sandwich panel is convenient to construct, and has relatively high air tightness, high heat insulating performance, relatively great corrosion resistance, and relatively great ageing resistance.

Description

technical field [0001] The invention relates to a cold storage sandwich panel. Background technique [0002] At present, cold storage sandwich panels have become the mainstream panels used in cold storage buildings, which are energy-saving and heat-insulating, and easy to install. However, the structure and installation method of the existing cold storage panels cannot guarantee good airtightness, and the sealing construction operation is inconvenient, and a large area of ​​the sealing strips is exposed to the air. After long-term use, these strips will age and fall off. It will lead to damage to the airtightness of the building and reduce the thermal insulation performance. This requires a new structure and installation system for the cold storage panel to achieve the purpose of reliable structure, convenient installation and durability. Contents of the invention [0003] The invention provides a sandwich panel for cold storage, which can not only improve air tightness,...
