Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] The torque return wind load automatic avoidance mechanism is composed of a mother column 1, a steel ball 2, a child column 3, a panel 4, a steel structure frame 5, a torsion spring 6, a rotating shaft 7 and steps 8. Three rectangular panels 4 are connected end to end to form a triangular prism, and the horizontal projection of the triangular prism is an isosceles triangle. The apex angle of the isosceles triangle is not greater than 30°, the vertically arranged sub-column 3 is located in the triangular prism, and the center of gravity of the isosceles triangle is located on the axis of the sub-column 3 . There is a steel structure frame 5 between the inner wall of the panel 4 and the sub-column 3, and the steel structure frame 5 is welded together with the inner wall of the panel 4 and the sub-column 3 as a whole. The lower end of the sub-column...

Abstract

The invention relates to a windproof mechanism of an advertising board, in particular to an automatic torque return wind load avoiding mechanism. The automatic torque return wind load avoiding mechanism is composed of a main column, a steel ball, an auxiliary column, face boards, a steel structure framework, a torsion spring, a rotating shaft and a step. Three rectangular face boards are connected end to end to form a triangular prism, the vertically-arranged auxiliary column is located in the triangular prism, the lower end of the auxiliary column is the whole rotating shaft integrated with the auxiliary column, the lower end of the main column is fixed with the ground, a vertical blind hole is formed in the top face of the main column, and the lower end of the rotating shaft is located in the blind hole. When fierce wind blows the face boards, the mechanism can automatically rotate to enable the smallest windward face to face the wind blowing direction. Therefore, the wind force suffered by the advertising board is reduced to be minimum, and the advertising board is protected against fierce wind damage on the premise that the steel product using amount is not increased.

Description

technical field [0001] The invention relates to a windproof mechanism for billboards, in particular to an automatic avoidance mechanism for torque return wind load. Background technique [0002] When the existing billboards located on both sides of the expressway encounter strong winds, because the billboards have a large surface area, once the wind direction is perpendicular to the board surface, the huge wind-receiving area of ​​the billboards makes it difficult for them to withstand huge wind force. Thereby collapse, twist, deflection and deformation occur. This poses a great threat to the safety of pedestrians, houses and vehicles near the billboard, and also brings greater maintenance and repair costs to advertisers. [0003] In order to avoid the above-mentioned accidents, billboard manufacturers have to increase the steel consumption of billboard columns and steel structure frames to increase their strength, and this action has greatly increased the production cost o...
