TECHNICAL FIELD

[0001] The utility model relates to the field of building engineering especially, relate to a high stability steel structure corridor structure of avoiding wind speed influence. BACKGROUND

[0002] With the development of building clustering and multifunction in the urbanization process, steel structure corridor, as a key component connecting different buildings and expanding the use space, is widely used. However, in actual working conditions, especially in the wind zone and coastal windy areas, the conventional steel structure corridor is plagued by wind speed. The conventional structure design of the corridor itself makes the windward surface directly face the wind load, and the strong wind pressure leads to unbalanced horizontal stress, causing significant shaking, endangering personnel passage and equipment installation. On the other hand, the continuous wind-induced vibration can easily cause structural fatigue damage and connection loosening, which buries safety hazards and shortens the service life. Therefore, innovative design is needed to improve its windproof and shock absorption performance. SUMMARY

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a high stability steel structure corridor structure of avoiding wind speed influence, comprising a steel structure corridor main body, a windproof assembly arranged on both sides of the steel structure corridor main body, the windproof assembly comprising a windproof louver grid and a streamlined wind wing plate uniformly arranged on the outer sides of the steel structure corridor main body, the windproof louver grid being arranged on the outer side of the steel structure corridor main body through a frame, the front end of a connecting shaft being connected to the middle part of the inner side of the wind wing plate through a spherical hinge, the rear end of the connecting shaft being provided with a bearing, a connecting cantilever being arranged on the steel structure corridor main body through welding or bolt fixation, a mounting hole being arranged on the outer end face of the connecting cantilever, the bearing being arranged in the mounting hole, and a pair of elastic adjusting assemblies being arranged between the connecting cantilever and the wind wing plate.

[0005] Further, the elastic adjusting assembly comprises a rubber column and a metal spring arranged on the front end of the rubber column, the rear end of the rubber column being fixedly arranged on the connecting cantilever through a connecting piece, and the front end of the metal spring being arranged on the wind wing plate through a connecting piece.

[0006] Further, the connecting shaft is made of high-strength alloy steel, a plurality of positioning through holes are uniformly arranged on the rear part of the connecting shaft in the circumferential direction, a plurality of positioning slots are arranged on the connecting cantilever, and the positioning through holes and the positioning slots are fixed through a bolt or a pin.

[0007] Further, at least one pair of limiting plates is symmetrically arranged on the outer periphery of the rear part of the connecting shaft, and at least one pair of limiting blocks is symmetrically arranged in the mounting hole of the connecting cantilever.

[0008] Further, the wind wing plate is made of aluminum alloy or light carbon fiber composite material.

[0009] Further, the windproof louver grid is arranged in staggered arrangement with an inclination of 35-45°.

[0010] The beneficial effects of the utility model are: the left and right inclination angles of the wind wing plate are adjusted according to actual conditions, the wind wing plate is locked after adjustment, the connecting shaft is rotated to adjust the up and down inclination angles of the wind wing plate, when the wind acts on the wind wing plate, the power of the wind will generate a torque around the shaft, the wind wing plate will also rotate around the connecting shaft under the action of the wind to change the own angle to achieve the purpose of adjusting the wind resistance and guiding the wind flow; after adjustment, the wind wing plate is fastened by a bolt or relies on a limiting block to limit the rotation angle of the wind wing plate; when the wind wing plate is subjected to wind load, the wind wing plate will transmit the force to the elastic connecting piece, since the elastic connecting piece has elasticity and damping characteristics, it can absorb and buffer the impact and vibration caused by the wind load, prevents the force from being directly transmitted to the connecting base and the main structure of the corridor, and reduces the shaking of the main structure of the corridor; the windproof louver grid changes the flow direction of the wind and disperses the pressure of the wind, and simultaneously plays a ventilation role; compared with the traditional steel structure corridor, the horizontal displacement amplitude of the utility model is reduced by more than 70% under strong wind, the shaking is significantly reduced, the risk of structural instability is almost zero, the safety use under extreme wind conditions is ensured, the wind-induced vibration fatigue damage is effectively inhibited, the service life of the main structure of the corridor is prolonged by 40%-50%, the frequent maintenance and maintenance investment is reduced, and the whole life cycle cost control and sustainable operation concept of the building are met; the part not described in detail of the utility model is the existing common technique.
