[0004] For example, the Chinese patent with the patent application number of 201010293529 discloses a bridge buffer viscous damper. This kind of buffer viscous damper is also mainly buffered by a liquid damping medium, so there is also the above-mentioned damping fluid leakage that causes the damper to fail. question

Embodiment 1
[0030] From attached figure 1 It can be seen that the present invention relates to a bridge buffer protection device structure, the piston can move back and forth under the push of the piston rod, the high-damping rubber element bears compression deformation, and the cylinder body limits the deformation of the high-damping rubber element. The high-damping rubber element in the cylinder is vulcanized by lamination of steel plate and rubber. When the bridge moves along the bridge direction, a load F is generated, which drives the piston rod to move. At this time, the piston rod moves without restriction. When the piston rod moves to a certain displacement and the piston contacts the high-damping rubber component, the high-damping rubber component begins to generate Reaction force, when the high damping rubber element is compressed to a certain displacement, the reaction force increases sharply, at this time the piston bridge buffer protection device is close to rigidity, limiti...

The invention discloses a piston-type bridge buffer protection method and device and a manufacture method. The piston-type bridge buffer protection device is installed on a bridge abutment on the two ends of the bridge. The piston-type bridge buffer protection device is in a single-piston structure; a piston is positioned in a piston cylinder; in the piston cylinder, two sides of the piston are respectively provided with multiple layers of elastic anti-vibration pads; each layer of elastic anti-vibration pad has different elasticity coefficients; two ends of the piston cylinder are provided with piston cylinder covers; a piston rod passes through one piston cylinder to extend out of the piston cylinder and is directly connected with a bridge support directly by an ear loop; and the pistoncylinder cover on the other end of the piston cylinder is installed on the bridge abutment. The device is in simple assembling structure, all construction members are all produced by factories, and the device is simple to manufacture and has low price. The device is convenient to carry out daily maintenance, only the position and the state of the piston need to be detected in the fixed time, and the risks that damping fluid leaks and fails and the like can be avoided.
Description
technical field [0001] The invention relates to a bridge protection method, device and manufacturing method, in particular to a bridge horizontal overload buffering protection method, device and manufacturing method. The device can buffer and protect the bridge structure when the bridge is subjected to an instantaneous impact. Background technique [0002] The bridge buffer protection device is applied to the abutments at both ends of the bridge to limit the horizontal displacement of the bridge along the bridge direction. Under normal circumstances, the device can slide freely with the thermal expansion and contraction of the bridge. In an emergency, the bridge is impacted by a horizontal load, and its impact force exceeds the predetermined design value. After the bridge support becomes invalid, the impact force pushes the bridge buffer protection device at this time to slow down the impact of external forces on the bridge and limit the impact of the bridge. Sliding, so as ...
