Anti-collision device and anti-collision method for force-transmitting damping and energy-dissipating concrete structure

Abstract

The invention discloses an anti-collision device and anti-collision method for a force-transmitting damping energy-consuming concrete structure, which comprises several force-transmitting damping energy-consuming units arranged in a straight line, arc or circle; each force-transmitting damping Energy dissipation units include collision system, restraint system, power conversion system and bottom plate; collision system includes collision plate, dowel bar and compression damping; restraint system includes sleeve, power conversion system includes crank, rotating shaft, diagonal stay rod and tension Damping; the position of the rotating shaft is fixed, the crank is set on the rotating shaft, one end is hinged to the dowel rod, and the other end is hinged to the diagonal tie rod; the middle part of the diagonal tie rod is installed with tension damping, and the bottom end is hinged to the bottom plate; the bottom plate is installed in the foundation. The invention transmits the horizontal impact force received by the collision system to the bottom plate through the power conversion system. During the force transmission process, the pressure damping and tension damping buffer and absorb energy, and finally transmit the impact energy to the ground, and the protective concrete structure is not affected by the impact force. impact, so as to achieve the purpose of protecting the concrete structure.

Description

Technical field [0001] The present invention relates to a collision device, in particular a force-collision device and a collision method for a force damping energy consumption concrete structure. Background technique [0002] Transportation's collision accidents in various piers, high frequency, direct or indirect cause a large amount of economic losses, and casualties, and the safety of engineering entities have also been made more challenges. [0003] Therefore, considering the use of engineering technology to reinforce and protect the concrete structure with anti-collision demand, how to significantly reduce the impact damage of collisions on the impact of the concrete structure is the consensus of the majority of engineering technicians. [0004] At present, most of the anti-collision design ideas are concentrated in setting buffering, diligent layer, absorb collision energy by damping materials or foam concrete, etc.. However, this anti-collision structure and waterproof, t...

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
