Roof billboard wind-resistant and vibration-isolated structure

Abstract

The invention discloses a wind-resistant and vibration isolation structure of a roof advertising board. The structure comprises an integral steel structure frame, support bases, vibration isolators, balance base structures, rotary shaft components and an advertising board surface. The integral steel structure frame comprises a plurality of right triangle lattice trusses, lattice trusses connected among the right triangle lattice trusses and inclined fork reinforcing frames; the support bases are symmetrically disposed on front node plates and rear node plates at the bottoms of the triangle lattice trusses; the vibration isolators are disposed between the front node plates and the rear node plates at the bottoms of the triangle lattice trusses and the support bases; the balancing bases are disposed at the bottoms of the triangle lattice trusses; the rotary shaft components are disposed between the middle node plates at the bottoms of the right triangle lattice trusses and the balancing bases; and the advertising board surface is mounted on the vertical surfaces, facing a street, of the right triangle lattice trusses. The wind-resistant and vibration isolation structure can eliminate wind load influence and prevent the damage of roof construction structures.

Description

technical field [0001] The invention relates to a billboard structure, in particular to a wind-resistant and vibration-isolated roof billboard structure capable of resisting wind pressure and vibration isolation. Background technique [0002] Roof billboard display is an important form of outdoor advertising. Roof billboard is the advertising form that can best reflect the characteristics of large screen and wide spread in outdoor advertising. The higher the level of the building, the wider the vision and the advertising effect. the better. As a result, there are more and more advertising boards on high-rise buildings, which have become a beautiful landscape of the city. [0003] The horizontal loads acting on tall buildings include wind loads and horizontal earthquakes. The effect of the wind is irregular, and the wind pressure changes continuously with the disorderly changes of wind speed and wind direction. Wind loads are dynamic loads that fluctuate over time. For hi...

Problems solved by technology

Due to the structural characteristics of the concrete structure, it is resistant to compression but not to tension. Under the constant tension, it will cause fatigue of the concrete structure and cause structural damage, which is easy to cause damage to the connecting parts and damage to the supporting system, especially in the case of strong winds.

Due to the high location of the billboard on the roof, once the advertising support system topples and the board falls, it will be a major safety accident with disastrous consequences
