Description

Bridge anti-seismic support capable of reducing use amount of foundation engineering

Technical Field

The utility model relates to the technical field of bridges, in particular to a bridge anti-seismic support capable of reducing the using amount of basic engineering.

Background

The bridge support is an important component for connecting and restraining the upper part and the lower part of the bridge, and the interaction of the bridge support and the upper part and the lower part of the bridge realizes that the bridge has constant load, transfers the moving load to the abutment and the foundation stone, and completes the deformation, horizontal displacement and corner required by a beam body structure, so that the support is particularly necessary for the bridge.

The difference of the supports often influences the force transfer condition between the upper part structure and the lower part structure of the bridge, thereby influencing the whole structure of the bridge.

The bridge support of prior art only can carry out the shock attenuation to the crane span structure unilateral, can't realize the absorbing effect of all directions of crane span structure horizontal plane, and simultaneously, current bridge support is difficult to maintain stably in strong wind environment to and when a little deviation appears in the crane span structure, can not in time give the maintainer early warning, lead to the problem that the crane span structure appears collapsing.

Further, the inside fixed mounting of support main part has the dead lever, the left and right sides fixed mounting of dead lever has touch switch, touch switch's outer wall fixedly connected with sensing line, the outer wall fixed mounting of support main part has the siren, the siren with sensing line fixed connection, the outer wall fixed mounting of rubber pad has the stripper plate, the stripper plate faces touch switch, produces the displacement back when the crane span structure, and the siren in time gives the effect that the maintainer police dispatch newspaper was reminded.

Furthermore, the touch switch is triggered intermittently, after the extrusion plate is contacted with the touch switch and the reaction time needs to be delayed, the alarm gives an alarm, and the touch switch gives an alarm only when the extrusion plate cannot be automatically reset.

Further, the siren with the figure one-to-one of rubber pad has realized that the crane span structure inclines towards which side, and the siren of this side sends out the police dispatch newspaper, has reached the effect of the accurate early warning of siren to crane span structure inclined position.

The utility model provides a bridge anti-seismic support capable of reducing the using amount of foundation engineering. The method has the following beneficial effects:

1. this reduce bridge antidetonation support of basic engineering quantity, through set up the ventilation hole of symmetry on support main part and crane span structure, the convection current of wind-force has effectively been realized, the driving force of wind-force to the crane span structure has been reduced, the anti-wind coefficient of crane span structure has been improved, because the crane span structure shakes, produce the extrusion facing to the kickboard, thereby drive the pole and drive the pulley and slide in the sliding seat is inside, thereby the sliding seat will produce the extrusion facing to the rubber pad that deflects, produce vibrations to the crane span structure through the rubber pad and eliminate, after the crane span structure vibrations are eliminated, the rubber pad is because self has elasticity, the rubber pad will drive the crane span structure and reset, because the kickboard is wrapping up each surface of crane span structure, after the crane span structure shifts towards arbitrary position on the horizontal plane, the kickboard homoenergetic drives the crane span structure and carries out the effect that resets.

2. This reduce bridge antidetonation support of basic engineering quantity, after receiving the extrusion through the rubber pad, the stripper plate will move towards touch switch, because touch switch has the delay response characteristic, after the rubber pad can't drive the stripper plate and reset, touch switch will give the siren circular telegram through the sensing line, give the maintainer through the siren and carry out the early warning, because board and siren one-to-one are held up, after the board is held up in the crane span structure extrusion, the siren of corresponding side will send out the police dispatch newspaper, the effect of reminding the maintainer to overhaul the position has been reached.
