Description
Technical Field

China is a country with frequent earthquakes, and recent earthquake disasters show that a main traffic channel is often damaged after an earthquake, which causes serious economic property loss, and a bridge is a throat of the main traffic channel, and the good and bad earthquake resistance of the bridge is directly related to the earthquake relief effect. Therefore, how to make bridge earthquake resistance is always a problem of important attention of students.
At present, the seismic isolation and reduction technology is mostly adopted as an engineering seismic resistance means, and the seismic isolation and reduction design method of the bridge requires selection of a proper seismic isolation and reduction device. The most common seismic isolation and reduction device is mostly applied to bridge pier supports, and can effectively control the internal force distribution of the structure.

In addition, the stability of a single lead core is poor, and fatigue shear failure can occur due to periodic repeated load or temperature influence in actual use, so that the damping performance and the self-resetting performance of the support are greatly reduced.
Under the action of an earthquake, the swinging of the friction swinging type shock insulation support can lift an upper structure (namely, a beam lifting phenomenon) and is difficult to adjust the height, which can cause a series of problems, such as deformation of a bridge structure of a bridge pier with unequal heights; meanwhile, the friction pendulum type shock insulation support depends on the action of friction force, the loss of the support is serious under the action of the friction force, the support is not easy to replace, and the cost of the support is improved in a phase change manner.

It should be noted that both the upper boom 4 and the lower boom 5 can be installed by using the height adjusting device 3, or only one of them can be installed by using the height adjusting device 3, so as to achieve the height adjustment of the damping device. For example: when only the upper boom 4 is installed using the height adjusting device 3, the lower boom 5 may be directly fixed to the lower seat plate 2 (the lower boom and the lower seat plate may be directly integrated).

The upper support plate 1 and the lower support plate 2 cannot move freely under the limitation of the plurality of shear pin devices 8, and the damping device has a movement function only after shear pins in the shear pin devices 8 are sheared under the action of an earthquake, so that the requirements of fixing the support are met; when an earthquake occurs, the shear pin is cut off, and the energy is consumed by moving through the sling 7 and the energy-consumption reset cable 6, so that the movement requirement of the bridge is met, and the energy-consumption shock insulation effect is realized.
Further, can adopt the sliding connection mode when one-way support demand that slides between shear force pin device 8 and upper bracket board 1 and the lower support board 2, specifically be: be equipped with slider 8.4 on the pin cover 8.1, all be equipped with spout 11 on upper bracket board 1 and the bottom suspension bedplate 2, slider 8.4 slides and sets up and realize upper bracket board and bottom suspension bedplate relative motion in spout 11.
Referring to fig. 1 and 3, during the unidirectional sliding support, a pair of shear pin devices 8 is arranged between the upper support plate 1 and the lower support plate 2, that is, the two shear pin devices 8 are arranged in a symmetrical manner, and at the moment, the upper support plate 1 and the lower support plate 2 can only move in the sliding direction of the sliding block, so that the unidirectional sliding requirement is met.
Of course, two pairs of shear pin devices 8 which are arranged in a sliding manner are illustrated in fig. 1 and 3, and since the sliding directions of the two pairs of shear pin devices 8 are perpendicular to each other, the requirements of a fixed support can be met when the shear pin devices 8 are connected with the upper support plate 1 and the lower support plate 2 in a sliding manner.
Further preferably, the upper support plate 1 and the lower support plate 2 are both provided with mounting holes 10, and the damping devices are connected with the beam body and the pier respectively through the mounting holes 10.
The technical scheme of the embodiment is specifically as follows:
according to actual requirements, a damping device of a fixed support, a bidirectional sliding support or a unidirectional sliding support type is selected, an upper support plate 1 is fixedly connected with a beam body by adopting a high-strength bolt, a lower support plate 2 is fixedly connected with a pier, and the damping device is installed.
When the damping device needs to be heightened, the locking bolts 3.2 and the locking nuts 3.3 on the upper support assembly and the lower support assembly are loosened, the upper suspension arm 4 and the lower suspension arm 5 are adjusted equally, so that the distance between the upper support plate 1 and the lower support plate 2 is changed, whether cushion blocks need to be added or not is judged according to the load borne by the damping device, if cushion blocks need to be added, cushion blocks with proper height are selected to be placed in the sleeve 3.1, and the locking bolts 3.2 and the locking nuts are locked after the damping device is adjusted to the proper height; meanwhile, the length of the energy consumption reset cable 6 is adjusted according to the adjusted height, and the sling 7 does not need to be adjusted because the upper support plate 1 and the lower support plate 2 are synchronously adjusted, and the distance between the sling installation surface A and the sling installation surface B cannot be changed, so that the length of the sling 7 does not need to be adjusted (when only one of the upper suspension arm and the lower suspension arm is installed by adopting a height adjusting device, the height adjustment only can change the distance between the upper support plate and the lower support plate, the distance between the sling installation surface A and the sling installation surface B cannot be changed, and the length of the sling 7 does not need to be adjusted).
By applying the technical scheme of the invention, the effects are as follows:
under the action of earthquake, the shear pins 8.2 are sheared (the bidirectional sliding support type damping device is not sheared by the shear pins), so that the beam body can swing within the allowed displacement range of the damping device. In the swinging process, the upper support plate 1 and the lower support plate 2 are relatively displaced, so that the energy consumption reset cable 6 is deformed, energy can be consumed, and earthquake response can be reduced. In the swing process, the sling 7 is always kept in a tight state, and the heightening device 3 is in close contact with the upper suspension arm 4 and the lower suspension arm 5 without relative movement, so that the bearing capacity of the damping device can be ensured, and the height of the damping device is fixed to prevent the beam lifting phenomenon.
The damping device can effectively prevent loss caused by friction in the whole swing process; after the earthquake, the energy consumption reset cable 6 has good self-resetting capability due to the characteristics of the SMA memory alloy, can return to the initial position, and the damping device has good self-resetting characteristics.
