Electricity-saving economical civil-engineering multiple-layer fixed goods shelf all-in-one novel refrigeration house

Abstract

The invention relates to an electricity-saving economical civil-engineering multiple-layer fixed goods shelf all-in-one novel refrigeration house which successively comprises an internal system, a totally-sealed waterproof moisture barrier system, a thermal insulation system and an external system from inside to outside and causes the refrigeration house to be systematized. The invention fills an intact net-type totally-sealed waterproof moisture barrier system outside an intact net-type insulation layer in the ground, and a totally-sealed waterproof moisture barrier system in a wall / roof insulation layer and compounds an I-type magic cube, an II-type magic cube and a insulation layer material required to be matched in the insulation layer so as to build an intact totally-sealed waterproof moisture barrier system and the thermal insulation system. The steel pipe column supported multiple-layer fixed rack is in a multi-purpose support load bearing structure as a whole in the house, steel pipe columns are welded on a steel plate embedded part in the reinforced concrete load bearing ground in the house, the specifications from bottom to top of lateral, longitudinal and diagonal rectangle steels among steel pipe columns are matched with load bearing requirements on the steel pipe columns and connection thereof is in standard welding.

Description

technical field [0001] The invention relates to a novel cold storage integrated with civil multi-layer fixed shelves for freezing, refrigerating and fresh-keeping food. Background technique [0002] In the civil engineering, thermal insulation, and refrigeration systems of the existing multi-storey civil cold storage, due to the lack of a fully enclosed waterproof and moisture-barrier system for protecting the thermal insulation layer, or only fragmentary waterproof and moisture-barrier layers, the existing multi-storey civil cold storage From the day when the cold storage was built, its insulation layer material was wetted by the moisture inside and outside the cold storage, so that the insulation function of the insulation material continued to decrease; The frame is mainly made of bricks, and its foundation part is due to the high load-bearing strength of the multi-layer reinforced concrete frame structure, and the bottom surface of the reinforced concrete column foundati...

AI Technical Summary

Problems solved by technology

Also because the pre-embedded steel parts of the hanging refrigeration pipes of the existing multi-storey civil cold storage are pre-embedded in the reinforced concrete beams, slabs, and side walls, the pre-embedded steel parts cannot be kept warm, and these pre-embedded steel parts are prefabricated Heavy-duty steel parts are integrated with reinforced concrete beams, slabs, and steel bars in side walls to form multiple strong cold bridges; The base is buried deep and has been in a relatively humid state for many years, so it is easy to exchange cold energy and heat energy. In winter, a strong exchange of cold energy and heat energy is formed between the geothermal heat. It can be transmitted to the outside world; these pre-embedded heavy steel parts pass through the insulation layer, and when they are cold, they will condense the moisture in the air into water and ice, soak the insulation layer, and destroy the reinforced concrete; and because the ground of the existing multi-layer civil cold storage There is no Rubik’s Cube support in the insulation layer, and the material of the insulation layer is insufficient for the reinforced concrete on the load-bearing ground and the cargo on the ground. After loading, the insulation layer is deformed and thinned, and cracks are formed at the connection between the side and the ground, which is easy to soak and conduct cold; The existing multi-storey civil cold storage has no Rubik's cube support on the ground at the outer door opening of the cold storage wall, so that the ground inside and outside the cold storage directly forms a reinforced concrete cold-conducting cold bridge; The internal cold energy of the existing multi-storey civil cold storage can be transmitted to the roof through the supporting brick columns and concrete columns; and because the existing multi-storey civil cold storage has a heavy reinforced concrete frame brick structure, the construction period is long and the construction cost High; the method for fixing the thermal insulation material on the wall of the known existing multi-layer civil engineering cold storage is: directly pass the fixed expansion bolt through the thermal insulation material to be fixed and fix it on the wall, and the expansion bolt forms a gap when passing through the thermal insulation material. That is, the gap between the fixed expansion bolt and the thermal insulation material and the gap between the fixed core of the fixed expansion plug itself and the fixed shell, this gap cannot be filled with the thermal insulation material, the fixing thickness of this fixing method is limited, and the fixing performance is poor , resulting in a permanent defect that reduces the thermal insulation function of the thermal insulation layer; also because the existing multi-storey civil cold storage needs to insulate all the inner surfaces of the reinforced concrete frame bricks, the thermal insulation area is large, the thermal insulation cost is high, and the thermal insulation effect of the beams and columns is better. Poor, unsafe and flammable, and it is impossible to establish a fully enclosed waterproof and moisture-proof layer system in the insulation layer; the existing multi-storey civil cold storage has reinforced concrete columns, reinforced concrete beams, reinforced concrete roofs, and reinforced concrete frames outside the warehouse. Brackets and moulds, both inside and inside the brick, increase the construction cost; the existing multi-storey civil cold storage has formed a congenital lack of a fully enclosed waterproof and moisture barrier system that must be in the insulation layer since the day it was established, and the cold storage system is incomplete. ; As a result, the quality of freezing and cold storage continues to decline, the daily temperature difference is large, the economic benefits are gradually reduced, the cold storage consumes more electricity, the cold energy is lost quickly, the production cost is high, and the construction cost is high.
