Description
Technical field
The invention belongs to anti-deicing experimental technique field, relate to freezing weather room cold-prevention bridge structure.
Background technology
Icing effect flight safety.Freezing weather room is verified for the ground experiment of aircraft anti-icing system, comprises icing, deicing and anti-icing experiment, and efficiency test bulk is 17m × 12m × 7m (long × wide × high).During test, freezing weather room temperature is (-5 ~-30) DEG C ± 5 DEG C, and cooling rate is 10 DEG C/h.After off-test, temperature rises to room temperature, programming rate 5 DEG C/h.
Due to the difference of local structure in the heat insulation structural of freezer, cause this position heat-proof quality to reduce, become the passage that cold transmits in a large number, be called " cold bridge ".Cold bridge can cause consumption cold to increase, the energy of waste refrigeration.Reinforced concrete structure is by cold bridge impact, and thawing more than 15 times structures cool-hot fatigue will occur repeatedly, and intensity is by decline 20% ~ 25%.
For avoiding cold bridge to occur, the backflow interlayer 9 of freezing weather room is first considered to adopt architectural conventional bracket to support.But the heat room plate 10 of freezing weather room can cut off by bracket, can not form continuous print insulation construction, and this structure maintain and replace is very difficult in the future.
The present invention, just for this difficult problem, supports backflow interlayer 9 with eight steel posts 11, and takes Insulation to ground, steel post 11 and surrounding wallboard and top board, form continuous print insulation construction, thus partition cold bridge, ensure the effect of refrigeration and cooling, ensure the safety of reinforced concrete structure.
Summary of the invention
The object of the invention is: solve freezing weather room cold bridge problem, prevent reinforced concrete structure intensity from declining, do not affect the test of freezing weather room.
Technical scheme of the present invention is: freezing weather room cold-prevention bridge structure, wherein:
Freezing weather room floor totally eight layers, is followed successively by from top to bottom: crossbeam 1, floor 2, leveling layer 3, heat insulation gas-bearing formation 4, warming plate 5, topping 6, bearing course 7 and steel plate 8;
The surrounding wallboard of freezing weather indoor and top board all post heat room plate 10, and the edge joint position of heat room plate 10 adopts hook pin locking hook boxlike syndeton.
The steel post 11 of freezing weather indoor is supported on leveling layer 3, steel post 11 circumfusion polyurethane foam plastics 12, and makes protective sleeve with corrosion resistant plate 13.
The sewer of freezing weather room adopts stainless steel tube 14, and the mouth of pipe welds with steel plate 8, and stainless steel tube 14 is surrounded by plastic bushing 15, is cast with polyurethane foam plastics 16 between stainless steel tube 14 and plastic bushing 15.
The advantage that has of the present invention and beneficial effect are: by this technical scheme, effectively reduce the chilling and shock heating change of reinforced concrete structure, ensure the safety of reinforced concrete structure, ensure the effect of refrigeration and cooling, do not affect the test of freezing weather room.
