Abstract

The invention discloses a deck type concrete filled steel tube arch bridge anti-seismic device, and relates to the technical field of novel arch bridge anti-seismic devices. The device comprises an oil storage buffer groove, an oil injection port blocking block, a supporting sliding shockproof force unloading structure and a concrete cast guide-out structure, an oil injection hole is formed in one end of the oil storage buffer groove, the oil injection port blocking block is connected with the inner side of the oil injection hole in a clamped mode, and the supporting sliding shockproof force unloading structure is fixedly connected into the oil storage buffer groove. Through the design of multiple sections of different types of anti-seismic supporting structures, the device can conveniently buffer and support vibration pressure led out of an arch bridge, the anti-seismic performance of the arch bridge is greatly improved, and through the design of casting the led-out structure through concrete, the device can conveniently inject stable anti-solidification concrete into a weight matching and adjusting supporting block, so that different weight supports are formed, and stable support for vibration is achieved.

Description

technical field [0001] The invention relates to the technical field of novel arch bridge anti-seismic devices, in particular to an above-supported type anti-seismic device for steel pipe concrete arch bridges. Background technique [0002] The arch bridge refers to the bridge with the arch as the main load-bearing member of the structure in the vertical plane. If the arch is formed in the powder layer in the container, it can bear the pressure of the upper powder without transmitting the pressure to the lower surface. It is called an arch bridge. In order to facilitate the support of the arch bridge, corresponding anti-vibration devices are required. However, the existing devices often lack corresponding buffer adjustment during use, thus lacking stable anti-vibration performance. Contents of the invention [0003] The object of the present invention is to provide an anti-seismic device for a concrete-filled steel tube arch bridge to solve the existing problem: the existin...
