Embodiment

[0044] figure 1 A schematic structural cross-sectional view according to an embodiment of the present invention is shown.

[0045] Such as figure 1 As shown, the bridge damping support includes:

[0046] The lower support plate 1, the top surface of the lower support plate 1 is provided with a guide post 2, a support spring 3, a boss 4, an annular groove 5, and a baffle 6. The guide post 2 is arranged around the lower support plate 1, and 3 sets of support springs On the guide post 3, the boss 4 is located at the center of the lower support plate 1, the top of the boss 4 is provided with an annular groove 5, and the baffle 6 is arranged outside the annular groove 5;

[0047] The upper support plate 7, the upper support plate 7 is provided with a guide post hole 8, a groove 9, and a connecting plate 10. The guide post hole 8 matches the guide post 8, the groove 9 is located on the bottom surface of the upper support plate 7, and the connecting plate 10 is located on the The top sur...

Abstract

The invention discloses a bridge shock absorption support which comprises a lower supporting board, an upper supporting board, a shock absorption device and a data sensor. The shock absorption deviceis located between the upper supporting board and the lower supporting board and comprises a lower installation seat, a cylinder block, sticky fluid, a piston and an upper installation seat, the lowerinstallation seat is fixedly connected with a boss and located through an annular groove, the cylinder body is installed on the lower installation seat and contains the sticky fluid, a sealed space is formed in the piston, a hole is formed towards the bottom of the piston, the cylinder body is sealed through the piston, the upper installation seat is installed in a groove of the upper supportingboard, and the piston is fixedly connected with the upper installation seat; and the data sensor is used for recording the number of times of pressure deformation of the bridge shock absorption support and the reciprocating stroke of the bridge shock absorption support. The bridge shock absorption support bears the load and meanwhile reduces vibration of a bridge and can adapt to the turning angleand the displacement of an upper structure, the upper structure can freely deform without generating extra additional internal force, and the bridge shock absorption support is used for bridges withlarge and medium spans.

Description

Technical field [0001] The invention belongs to the field of bridges, and more specifically, relates to a bridge damping bearing. Background technique [0002] The bridge support is installed on the pier and the top surface supports the device of the bridge superstructure. Its function is to fix the superstructure to the pier, bear various forces acting on the superstructure, and reliably transmit it to the pier; under the action of load, temperature, concrete shrinkage and creep, the support can adapt to the superstructure The rotation angle and displacement of the superstructure can be freely deformed without additional internal force. The existing bridge bearings are mainly plate rubber bearings. This type of bearing has sufficient vertical rigidity to withstand vertical loads but cannot achieve the effect of damping. It is not suitable for large and medium-span bridges. [0003] Therefore, it is necessary to develop a bridge bearing with damping effect, which is suitable for ...
