Force transmission type damping energy dissipation concrete structure anti-collision device and anti-collision method

Abstract

The invention discloses a force transmission type damping energy dissipation concrete structure anti-collision device and an anti-collision method. The anti-collision device comprises a plurality of force transmission type damping energy dissipation units which are distributed in a linear or arc or circular mode, wherein each force transmission type damping energy dissipation unit comprises a collision system, a constraint system, a power conversion system and a bottom plate, each collision system comprises a collision plate, a dowel bar and a pressed damper, each constraint system comprises asleeve, each power conversion system comprises a crank, a rotating shaft, a diagonal draw bar and a tension damper, the position of each rotating shaft is fixed, the crank is sleeved on each rotatingshaft, one end of each rotating shaft is hinged with the dowel bar, the other end of each rotating shaft is hinged with the diagonal draw bar, the middle of each diagonal draw bar is installed with the tension damper, the bottom end of each diagonal draw bar is hinged with the bottom plate, and the bottom plate is installed in a foundation. According to the anti-collision device, horizontal impact force borne by the collision systems is transmitted to the bottom plates through the power conversion systems, pressed damper and tension damper are buffered and absorb energy in the force transmission process, impact energy is finally transmitted to the ground, a concrete structure is protected against the influence of the impact force, and therefore the purpose of protecting the concrete structure is achieved.

Description

technical field [0001] The invention relates to an anti-collision device, in particular to an anti-collision device and an anti-collision method of a force transmission type damping energy-consuming concrete structure. Background technique [0002] The collision accidents of vehicles on various piers occur frequently, directly or indirectly causing a large number of economic losses and casualties, and also pose more challenges to the safety of engineering entities after being collided. [0003] Therefore, it is very important to consider the use of engineering technology to strengthen and protect concrete structures with anti-collision requirements. How to greatly reduce the impact force of collisions on concrete structures is the consensus of the majority of engineering and technical personnel. [0004] At present, most of the anti-collision design ideas are concentrated on setting up buffer and energy dissipation layers, and absorbing collision energy through damping mater...

AI Technical Summary

Problems solved by technology

When a large-volume object (such as a car, truck, etc.) impacts a concrete structure, the impact force will be much greater than the buffering and energy dissipation effect of the anti-collision material itself, so the concrete structure will be damaged by a certain degree of impact, thereby affecting the impact on the upper concrete structure. reliable support

[0006] 2. When the concrete structure is damaged by impact, the repair process is complicated, difficult and cumbersome

[0007] 3. Among the existing anti-collision materials, most of the dampers are easy to age due to the organic material (rubber) in the composition, and the service life is not long

[0008] 4. In order to avoid the impact damage of the concrete structure, it is necessary to increase the thickness of the anti-collision material to increase the buffer force, so that the thickness of the anti-collision material around the concrete structure is bloated, occupying the space of the road or waterway
