Problems solved by technology

[0003] When the current bridges are built in different geological regions, unexpected earthquakes will occur in some areas due to different geographical locations. If the impact force of the earthquake on the bridge cannot be buffered in time, it is easy to cause the supporting columns of the bridge to be damaged. The bottom of the bridge surface is broken or shifted, causing the main body of the bridge support column to be damaged, which affects the safe use of the entire bridge. The force at the connection between the columns is constantly changing. If the seismic buffering capacity of the bridge damper cannot be further improved, the seismic capacity of the entire bridge will be very limited.

Embodiment 1

[0030] Example 1, as figure 1 , 3 As shown in , 4, 5 and 7, when the top of the upper connecting plate 1 is subjected to a large force, the upper connecting plate 1 drops a little distance, the slider 803 slides down inside the chute 806, and the movable rod 802 is in the square The inside of the groove 804 slides down a little. At this time, the shock-absorbing spring 805 is shortened by force and stores a certain elastic potential energy, which buffers the force on the upper connecting plate 1. If the force on the upper connecting plate 1 is large, the upper connecting plate When the bottom of the plate 1 is in contact with the top of the outer limit ring 5, a part of the force received by the upper connecting plate 1 will be transmitted to the body of the installation bin 9. Since the interior of the square groove 804 is evenly provided with a plurality of groups of through holes 808, The inside of the hole 808 is provided with a "Z"-shaped tough steel rod 807, which great...

Embodiment 2

[0031] Example 2, as Figure 1-3 As shown, when the force on the upper connecting plate 1 is constantly changing, the distance between the upper connecting plate 1 and the lower connecting plate 3 is continuously slightly shortened or elongated, so that the roller 701 continuously rolls back and forth at the bottom of the upper connecting plate 1 , the connecting rod 704 is forced to rotate forward and reverse by a certain angle with the shaft 702 as the axis, and when the two groups of rollers 701 roll close to each other, the buffer spring A 705 is stretched to store elastic potential energy, and the buffer spring B 707 is also connected by the two groups The rod 704 is elongated to store elastic potential energy, and when the distance between the upper connecting plate 1 and the lower connecting plate 3 is slightly increased, the two groups of rollers 701 roll away from each other, and the buffer spring A 705 and the buffer spring B 707 are both shortened and released. Stor...

Abstract

The invention discloses a palace-shaped box-type mild steel damper applied to bridges and structural engineering. An outer casing is arranged at the position, and an outer limit ring is arranged on the top of the outer casing, an inner casing is arranged on the inner side of the outer casing, and an upper connecting plate is arranged on the top of the inner casing. In the present invention, the upper connecting plate, the fixing hole, the lower connecting plate, the energy-absorbing and shock-absorbing component and the installation bin are used together, so that when the distance between the upper connecting plate and the lower connecting plate changes slightly, the force on the bridge passes through the movable rod. It is transmitted to the shock-absorbing spring, and the force on the damper is buffered by the shock-absorbing spring, which greatly ensures the stability of the connection between the bridge support column and the bottom of the bridge deck, and avoids damage to the bridge due to excessive force. To ensure the safe use of the entire bridge.

Description

technical field [0001] The invention relates to the technical field of mild steel dampers, in particular to a palace-shaped box-type mild steel damper applied to bridges and structural engineering. Background technique [0002] my country is located at the junction of the Pacific Rim seismic belt and the Eurasian seismic belt, and is a country prone to earthquakes. In order to minimize the losses caused by earthquake disasters, it is necessary to carry out seismic design and reinforcement of engineering structures such as buildings and bridges. The traditional seismic design uses the deformation of the structure itself to resist and consume seismic energy, so as to meet the seismic requirements of the structure and reduce the vibration of the structure. The control technology is to add a specific energy dissipation element to the structure. Under the action of earthquake, the structure mainly relies on this specific energy dissipation element to absorb and dissipate the seis...
