Description
Technical field
The invention belongs to anti-deicing experimental technique field, relate to freezing weather chamber cold-prevention bridge structure.
Background technology
Icing effect flight safety.Freezing weather chamber is for the ground experiment checking of aircraft anti-icing system, comprises icing, deicing and anti-icing experiment, and efficiency test bulk is 17m * 12m * 7m (length * wide * height).During test, freezing weather room temperature is (5～-30) ℃ ± 5 ℃, and cooling rate is 10 ℃/h.After off-test, temperature rises to room temperature, 5 ℃/h of programming rate.
Due to the difference of local structure in the heat insulation structural of freezer, cause that this position heat-proof quality reduces, become a large amount of passages that transmit of cold, be called " cold bridge ".Cold bridge can cause consumption cold to increase, the energy of waste refrigeration.Reinforced concrete structure is subject to cold bridge impact, and cold and hot fatigue will occur 15 above structures of thawing repeatedly, and intensity will decline 20%～25%.
For avoiding cold bridge to occur, the backflow interlayer 9 of freezing weather chamber first considers to adopt architectural conventional bracket to support.But bracket can cut off the heat room plate of freezing weather chamber 10, can not form continuous 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 ground, steel post 11 and surrounding wallboard and top board is taked to Insulation, form continuous insulation construction, thereby partition cold bridge, guarantees refrigeration and the effect of lowering the temperature, and guarantees the safety of reinforced concrete structure.
Summary of the invention
The object of the invention is: solve freezing weather chamber cold bridge problem, prevent that reinforced concrete structure intensity from declining, and do not affect the test of freezing weather chamber.
Technical scheme of the present invention is: freezing weather chamber cold-prevention bridge structure, wherein:
Totally eight layers of freezing weather room floors, are 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;
Surrounding wallboard and top board that freezing weather is indoor all post heat room plate 10, and the edge joint position of heat room plate 10 adopts hook pin locking hook boxlike syndeton.
The indoor steel post 11 of freezing weather is supported on leveling layer 3, steel post 11 circumfusion polyurethane foam plastics 12, and make protective sleeve with corrosion resistant plate 13.
The sewer of freezing weather chamber adopts stainless steel tube 14, the mouth of pipe and steel plate 8 welding, and stainless steel tube 14 is surrounded by plastic bushing 15, between stainless steel tube 14 and plastic bushing 15, is cast with polyurethane foam plastics 16.
The advantage having of the present invention and beneficial effect are: by this technical scheme, the chilling and shock heating that effectively reduces reinforced concrete structure changes, guarantee the safety of reinforced concrete structure, guarantee the effect of refrigeration and cooling, do not affect the test of freezing weather chamber.
