Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Such as figure 1 , 2 As shown in , 3 and 4, the support 3 is installed on the cover beam 1, the main beam 2 is arranged on the support 3, and rectangular structural grooves are reserved at both ends of the cover beam 1 during pouring. A U-shaped steel box-shaped rigid block 7 formed by welding is arranged on the straight section in the middle of the U-shaped flexible block 8, and a rigid cover plate is arranged on the inside and the top of the rigid block 7. A plurality of springs are arranged in the rigid block 7, and one end of the spring is anchored to the inner wall of the rigid block 7, and the other end is connected to the rigid cover.

[0024] The flexible block 8 is a U-shaped elastic rubber sealed cabin with a liquid filling port 10, and its internal filling 9 can be liquid or gas with low compressibility; when the two ends of the cove...

Abstract

The invention discloses a bridge anti-seismic device provided with hill type flexible check blocks. The bridge anti-seismic device comprises the two U-shaped flexible check blocks which are arranged at the two ends of a bent cap respectively and are of the same structure. A U-shaped rigid check block is arranged in the flexible check block, and a rigid cover plate is arranged at the upper part inthe rigid check block; one end of each spring is connected with the inner wall of the corresponding rigid check block, and the other end of each spring is connected with the rigid cover plate of the corresponding rigid check block. The device can effectively buffer and resist the earthquake action to reduce beam falling accidents, can reasonably integrate multiple functions such as limiting, buffering energy consumption and resetting, has multiple defense lines, and is easy to reset after an earthquake.

Description

technical field [0001] The invention relates to the technical field of bridge anti-seismic and anti-seismic isolation, in particular to a bridge anti-seismic device provided with hill-type flexible stoppers. Background technique [0002] According to the earthquake disaster data over the years, it is not difficult to find that beam falling accidents often occur in bridge structures due to inadequate vertical and horizontal restraint measures. The falling beam accident not only brings great difficulties to the post-earthquake maintenance of the bridge structure, but also seriously interferes with the traffic lines under the bridge. With the continuous deepening of people's understanding of earthquake disasters and structural seismic responses, more and more attention has been paid to structural earthquake resistance and related seismic isolation measures in the process of structural design and construction. Effective shock-isolation devices are hotspots in the field of civil...
