Abstract

The invention relates to a built-in locking type multifunctional adjustable damper and a bridge structure. The built-in locking type multifunctional adjustable damper comprises: a cylinder body, internally provided with a damping piston and damping liquid; a piston rod, wherein one end of the piston rod extends into the cylinder body and is fixed with the damping piston; and a locking fastener, arranged in the cylinder body, wherein the cylinder body and the piston rod are locked or unlocked by controlling the locking fastener to be in contact with or separated from the piston rod. According to the built-in locking type multifunctional adjustable damper and the bridge structure, the built-in locking type multifunctional adjustable damper can be used in various states of a bridge and does not need to be detached after the bridge is built, the permanent and temporary combination effect is achieved, tower beam temporary consolidation device resources in the cable-stayed bridge construction process are saved, construction procedures and links are reduced, the project progress is accelerated, construction centralized control operation is facilitated, the construction quality and safety are ensured, and the anti-seismic function of the finished bridge state is enhanced.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to a built-in locking multifunctional adjustable damper and a bridge structure. Background technique [0002] A cable-stayed bridge is a bridge in which the deck system is under compression and the supporting system is under tension. The supporting system is composed of cables. Although the construction of cable-stayed bridges in my country started late, it has developed rapidly. The Shanghai Yangpu twin-tower space double-cable plane steel-concrete composite girder cable-stayed bridge built in 1993 has maintained a world-leading 602m main span record for 6 years. In 2008, the Sutong Yangtze River Bridge cable-stayed bridge has maintained a world-leading record with a main span of 1088m. Although the cable-stayed bridge has a large spanning capacity, its construction is also difficult, and the construction and use risks of the cable-stayed bridge are also high. Displacement, torsio...
