Energy consuming shock absorbing node of assembled bridge pier

Abstract

The invention relates to an energy consuming shock absorbing node of an assembled bridge pier and belongs to the technical field of bridge engineering. The energy consuming shock absorbing node of the assembled bridge pier mainly comprises a capping beam and a bridge pier; the capping beam is arranged at the upper end of the bridge pier; members such as a capping beam gap, a clamping block and a high strength spring are arranged at the bottom of the capping beam; and members such as a viscous fluid damper and a pile body are arranged on the bridge pier. Firstly, the bridge pier is placed and well fixed; a crane hoists the capping beam, substantially aligns the capping beam, slowly lowers the capping beam and adjusts the capping beam in time by observing the situation of the clamping block; and after the capping beam completely falls, the viscous fluid damper is hinged at the two ends to finish mounting. The energy consuming shock absorbing node of the assembled bridge pier has the advantages that the bearing force is higher, the construction is more convenient, the energy consuming shock absorbing node of the assembled bridge pier is beneficial for shortening the construction period, problems such as collision caused by inaccurate mounting and alignment of a traditional method can be effectively solved, shock can be furthest absorbed when an earthquake occurs, and the traffic capacity of a bridge can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, and in particular relates to an energy-dissipating and shock-absorbing node of an assembled bridge pier. Background technique [0002] At present, the construction method of in-situ pouring is mainly adopted for the substructure of bridges in our country. On-site pouring construction often has a long construction period, a large amount of labor, and the construction quality is not easy to guarantee, and it has a great impact on the surrounding environment. In order to overcome these adverse effects, the form of fabricated bridge piers came into being. Compared with traditional cast-in-place piers, prefabricated piers have the advantages of short construction period, low environmental impact, and high construction quality, which meet the development requirements of the industrialization of building structures in my country. With urban modernization and rapid economic development, urba...

Problems solved by technology

[0004] In order to solve the above-mentioned existing technical problems, the present invention provides an energy-dissipating and shock-absorbing node of a prefabricated bridge pier, mainly for the purpose of developing a joint with higher bearing capacity, more convenient construction, and shortening the construction period, which can effectively solve the problem of installation alignment in the previous methods. It is not allowed to cause bumps and other problems. When an earthquake occurs, it can absorb the shock to the maximum extent and ensure the traffic capacity of the bridge.
