Low-temperature grain depot heat insulation system and construction method thereof

Abstract

The invention provides a low-temperature grain depot heat insulation system and a construction method thereof. The system comprises a bin wall outside heat insulation system, a bin wall (3) and a bin wall inside heat insulation system. The bin wall outside heat insulation system is formed by forming a plastering layer (2) on the outer side of the bin wall (3) and coating a heat reflection coating facing layer (1) on the outer side of the plastering layer (2), the bin wall inside heat insulation system is composed of a steam isolating layer (4), a fixing member (5), a heat insulation layer (9) and a plaster protection layer (10), the steam isolating layer (4) is arranged between the heat insulation layer (9) and the bin wall (3), the fixing member (5) capable of bearing pressure is adopted to fix the heat insulation layer (9) and the steam isolating layer (4) on the bin wall (3), and the plaster protection layer (10) is plastered on the outer side of the heat insulation layer (9). The invention further provides a construction method of the low-temperature grain depot heat insulation system. The low-temperature grain depot heat insulation system has heat insulation effect, has performance of resisting lateral pressure, is longer in service life and can be widely applied to wall heat insulation of a house type bin of a concrete structure or a building body structure.

Description

technical field [0001] The invention relates to a low-temperature grain storage facility and a construction method thereof, in particular to a low-temperature grain storage insulation system and a construction method thereof. Background technique [0002] The low-temperature grain depot is a kind of grain storage facility commonly used in modern storage technology. It mainly controls the physical factor of "temperature" to keep the grain in a certain low temperature state, which can effectively limit the life activities of the organisms in the grain pile and reduce the The loss of stored grain delays the aging of grain and increases the storage stability of grain. [0003] At present, mechanical refrigeration technology is usually used to maintain the low-temperature environment in low-temperature grain depots at home and abroad. According to calculations, about 30% to 35% of the cooling consumption is through the enclosure structure. Therefore, in order to maintain the low...

Problems solved by technology

The keel part of this heat preservation method cannot be insulated and easily becomes a cold bridge, the heat preservation effect is not good, and the construction process is complicated and the construction cost is high

And in the prior art, the polyurethane spray foam layer, the mortar-filled steel wire mesh layer and the putty surface are used on the inner wall from the main wall to the inside, and the steel wire mesh is directly adhered to the polyurethane spray foam layer, or through the polyurethane spray The plastic bolts that have been fixed on the main wall before spraying and foaming will easily cause the polyurethane sprayed foam layer to be deformed under pressure, and there are also quality risks
