Background
With the rapid development of Chinese economy, the use of the refrigeration house in national production is increasing, and the refrigeration house investment construction as a core infrastructure matched with cold chain logistics is in a rapidly growing situation under the double promotion of government policy encouragement and vigorous demand of fresh food market. Many old factory buildings or warehouses in the market need to be reformed into a cold storage for use at present, but as the materials such as plastering, putty and the like adopted by the original building construction process are always reserved on the surface of the ceiling designed in the prior art, the cohesiveness between the materials and polyurethane cyanide is poor, if the putty is not removed, the heat insulation layer of the ceiling is very easy to fall off after the heat insulation construction of the cold storage is finished, but the materials are difficult to be completely removed due to the fact that the materials are fully adhered with the wall body in the daily period, and the labor cost of removing is high, so that a heat insulation structure specially suitable for reforming the old building with the materials such as plastering, putty and the like into the cold storage ceiling is needed.
Disclosure of Invention
In order to solve the technical problems in the background art, the utility model provides a heat preservation structure of a refrigerator ceiling.
The utility model adopts the following technical scheme: a heat insulation structure of a refrigerator roof comprises a roof base surface; the bottom surface of the ceiling foundation surface is fixedly provided with a plurality of L-shaped steel plate pieces through expansion bolts; the L-shaped steel plate pieces are arranged in an array manner; round steel suspenders are arranged on the outer side surfaces of the right-angle sides of the L-shaped steel plate pieces; the tail end of the round steel suspender is connected with a plurality of square tube keels; the square tube keels are transversely and longitudinally staggered to form a skeleton net; the bottom surfaces of the square tube keels are provided with outer color protection steel plates; the outer color protection steel plates are fixed on the square tube keels through self-tapping screws; the upper surface of the skeleton net is sprayed and coated in a layered manner to form a polyurethane heat-insulating layer; and a broken cold bridge boss is arranged at the joint of the polyurethane heat-insulating layer and the round steel suspender.
Further, the height of the broken cold bridge boss is not smaller than 300mm.
Further, the upper surfaces of the polyurethane heat-insulating layer and the broken cold bridge boss are coated with a glass fiber reinforced plastic protective layer.
Compared with the prior art, the utility model has the advantages that: the heat-insulating structure of the refrigerator ceiling designed by the utility model can directly hoist square pipe keels and outer color-protecting steel plates at the hoisting points below the cleaned ceiling surface layer, and the polyurethane heat-insulating layer is sprayed on the upper layer, so that the original ceiling putty is not removed, a great deal of manpower is saved, the cost is reduced, and the construction progress is improved. The mode that this structure adopted ceiling furred ceiling dragon skeleton net and various steel sheet makes the structure firm more, durable, and the heat preservation is more simple and convenient, swift in furred ceiling top construction, quality and result of use in can fully guaranteeing whole freezer insulation system life cycle, and this structure makes the ceiling heat preservation whole more pleasing to the eye.
