Description

Continuous heat-preservation cold-bridge-free three-dimensional refrigeration house and construction method thereof

Technical Field

The invention relates to the field of cold storages, in particular to a continuous heat-preservation cold bridge-free three-dimensional cold storage and a construction method thereof.

Background

The cold storage is mainly used for freezing processing and cold storage of foods, and the cold storage keeps a certain low temperature indoors through artificial refrigeration. Therefore, the walls, floors and flat tops of the refrigerator need to be provided with heat insulation materials with certain thickness so as to reduce the heat transmitted from the outside. The function of the cold storage is different from that of common industrial and civil buildings, not only the diffusion of water vapor and the permeation of air are prevented, but also the invasion of outdoor air is prevented to increase the cold consumption of the cold storage, and the moisture condensation is prevented to cause the damp and freezing damage of a building structure, particularly a heat insulation structure, so that the cold storage has a unique structure, and the construction of the cold storage is provided with a damp-proof heat insulation layer to ensure that the cold storage building has good sealing property and damp-proof steam-proof performance. The construction technology of the peripheral plate near the top of the cold storage tends to be mature, and the improvement space is not large.

However, the foundation layer on the bottom surface of the refrigeration house is easily affected by low temperature, water in soil is easily frozen, and in order to avoid the problem that the refrigeration house leaks cold to the ground to cause the soil to freeze, the existing method is to dig a deep foundation pit, lay a thick heat insulation layer, and then perform multiple processes of water prevention, concrete pouring and the like on the heat insulation layer, wherein the heat insulation layer bears the weight of the whole main structure. The mode needs to dig a lot of earthwork, and the cost is high; waiting is needed before the next procedure, and the construction time is long; the material consumption is large. Furthermore, the traditional passage door of the refrigeration house mainly adopts the modes of manual opening and closing, motor control and the like. When goods are delivered into and delivered out of a warehouse, a door body of the refrigeration house needs to be completely opened, and due to the fact that the temperature difference between the inside and the outside of the refrigeration house is large, the cold leakage phenomenon is very serious, the temperature of the refrigeration house is difficult to maintain specific refrigeration requirements, the refrigeration effect of the refrigeration house is poor, and frozen goods deteriorate; in addition, the microthermal special environment of freezer is unfavorable for the staff work, works under this kind of freezer environment for a long time moreover, is unfavorable for that the staff is healthy. Therefore, mechanization and unmanned development have been the direction of the development of the refrigerator. The manual opening and closing of the passage door of the refrigeration house is gradually replaced by a novel door opening mode. The cold leakage problem when the goods was access can't be solved to current single structure of opening the door.

Therefore, the continuous heat-preservation cold-bridge-free three-dimensional refrigeration house which is convenient to construct, low in cost, capable of prolonging the service life of the refrigeration house and free of cold leakage and the construction method thereof are designed by researching the overall heat-preservation structure of the refrigeration house.
