The invention belongs to the technical field of ice preventing and removing tests and relates to a cold-bridge-preventing structure for a freezing climate chamber. The floor of the freezing climate chamber is provided with eight layers, namely a beam (1), a floorslab (2), a leveling layer (3), a heat and moisture insulation layer (4), a heat insulation plate (5), a protective layer (6), a pressure bearing layer (7) and a steel plate (8), arranged from bottom to top in sequence. Heat insulation storage panels (10) are attached to surrounding wall plates and a top plate inside the freezing climate chamber, and the abutted seams of the heat insulation storage panels (10) are respectively of a hook pin locking hook box type connecting structure. By means of the scheme, a continuous heat insulation structure is formed, intense cold and intense heat change of a reinforced concrete structural member is effectively reduced, the safety of the reinforced concrete structural member is guaranteed, the refrigerating and cooling effect is guaranteed, and the test of the freezing climate chamber is not affected.
Description
technical field [0001] The invention belongs to the technical field of anti-icing test and relates to an anti-cold bridge structure of an icing climate chamber. Background technique [0002] Icing affects flight safety. The icing climate chamber is used for the ground test verification of the aircraft anti-icing system, including icing, deicing and anti-icing tests. The effective test space size is 17m×12m×7m (length×width×height). During the test, the temperature of the icing climate chamber is (-5~-30) °C ± 5 °C, and the cooling rate is 10 °C / h. After the test, the temperature was raised to room temperature at a rate of 5°C / h. [0003] Due to the difference in the local structure of the heat insulation structure of the cold storage, the heat insulation performance of this part is reduced, and it becomes a channel for a large amount of cold transfer, which is called a "cold bridge". Cold bridges will increase cooling consumption and waste cooling energy. Reinforced conc...
