Abstract
The utility model relates to the slideable Antivibration block for bridge of a kind of embedding, include block (1), it is characterized in that: in block (1), be provided with groove (2), in groove (2), block rubber (4) is set by elastic washer (3), the end of block rubber (4) is located at groove (2) outward, upper edge in described groove (2) and lower edge are respectively equipped with feather key (5), relative feather key (5), block rubber (4) is provided with suitable chute (6).The utility model is compared with general anti-knock block, and its meeting extending structure vibration period, owing to leaving certain gap between block and beam body, under the geological process of low middling, whole system is in a safe condition.Once generation macroseism, when the displacement of beam body exceedes block gap value, in block, namely block rubber starts to slide, and block rubber restriction simultaneously produces displacement and consumed energy, and anti-stop block damages and the beam that falls occurs.
Description
Technical field
The utility model relates to a kind of bridge stopping means, is the slideable Antivibration block for bridge of a kind of embedding specifically.
Background technology
In recent years, the measure of block shockproof control is an active branch in bridge construction antidetonation always, comprise structure active and Passive Control and both and combine control, the frictional resistance arranging rubber absorbers or damper between beam body and block consumes energy to realize damping object.But these measures often exist very large defect: on the one hand, the damper through designing was once lose efficacy, and the not only original object that arranges does not reach, and also may produce unexpected bad effect; On the other hand, damper and damper be arranged so that establishing of bridge is costly.The setting of bridge shockproof block prevents superstructure from producing excessive displacement or the beam that falls.The shockproof effect of block is not only relevant to the intensity of block, and there is close relationship with the gap etc. of the type of block, rigidity, block and beam body.When arranging the block of different-stiffness, block rigidity reduces, and block drag peak value reduces, and block and superstructure interactional time also increase, and namely impact force reduces.Therefore, in ordinary concrete block, set up one deck slidably flexible material, reduce block initial stiffness, buffering earthquake stress, its shockproof effect be improved significantly.
Summary of the invention
The purpose of this utility model is to disperse and alleviate superstructure seismic load and the active force to abutment and pile foundation, providing a kind of and embed slideable Antivibration block for bridge.Realizing the technical scheme that the purpose of this utility model takes is: a kind ofly embed slideable Antivibration block for bridge, include block, it is characterized in that: in block, be provided with groove, in groove, block rubber is set by elastic washer, the end of block rubber is located at outside groove, upper edge in described groove and lower edge are respectively equipped with feather key, relative feather key, and block rubber is provided with suitable chute.
The utility model is preformed groove in ordinary concrete block, groove is embedded in a block rubber part, remainder exposes block, embedded whole block rubber is connected by elastic washer with between block, ordinary concrete block inwall arranges fixing several feather key, be provided with chute around block rubber, feather key embeds in chute, leaves certain gap between block and beam body.When block rubber is subject to horizontal earthquake load, can horizontal slip by elastic washer and chute, consume seismic energy, protection block, restrainer.
The utility model is compared with general anti-knock block, and its meeting extending structure vibration period, owing to leaving certain gap between block and beam body, under the geological process of low middling, whole system is in a safe condition.Once generation macroseism, when the displacement of beam body exceedes block gap value, in block, namely block rubber starts to slide, and block rubber restriction simultaneously produces displacement and consumed energy, and anti-stop block damages and the beam that falls occurs.

Detailed description of the invention
With reference to accompanying drawing, the slideable Antivibration block for bridge of a kind of embedding, include block 1, it is characterized in that: in block 1, be provided with groove 2, arrange block rubber 4 by elastic washer 3 in groove 2, the end of block rubber 4 is located at outside groove 2, and the upper edge in described groove 2 and lower edge are respectively equipped with feather key 5, relative feather key 5, block rubber 4 is provided with suitable chute 6.
During use, the utility model is placed on the bridge pier 7 of beam body 8 both sides, between block rubber 4 and beam body 8, has gap, then the utility model and bridge pier 7 are fixed together.
