Summary of the invention
The object of the present invention is to provide the inner air bearing rigidity of a kind of single story building model in wind tunnel analogue means; Make it can regulate single story building model internal capacity neatly; Thereby change the inner air bearing rigidity of BUILDINGS MODELS, thereby lay the foundation for carrying out the research of single story building wind load test.
The technical solution adopted for the present invention to solve the technical problems is:
Four open circles steel pipe bottom vertical are installed on wind-tunnel turntable periphery, and four open circles steel pipe top are fixed with the wind-tunnel rotating disk, and said wind-tunnel center of turntable is equipped with detachable disk, and detachably disc centre has hole; On the wind-tunnel turntable between four open circles steel pipes through the round rubber pad; Be mounted with an organic glass container of forming by little cylinder of epimere and hypomere large cylinder; Be equipped with the annular rubber pad between the annular rim of a cup of organic glass container and the wind-tunnel disk lower surface; The organic glass axis is coaxial with the rotating shaft of wind-tunnel turntable, and described organic glass container upside is equipped with inlet valve, and downside is equipped with flowing water Valve.
Described organic glass container outside diameter is less than the diameter of detachable disk, and described organic glass container end diameter is greater than the diameter of hole.
Described organic glass container upper edge vertically indicates rule.
The beneficial effect that the present invention has is:
The present invention can through water level in the Inlet and outlet water valve regulated container, regulate the model in wind tunnel internal capacity thereby reach according to the requirement of single story building model wind tunnel test.This device can accurately be regulated the inside air bearing rigidity of single story building model in wind tunnel, lays the foundation for carrying out the research of single story building wind load test.
