Abstract
The utility model relates to an anti-seismic connecting rod beam fall-proof structure. The anti-seismic connecting rod beam fall-proof structure comprises beam bodies, bridge pillars and connecting beams, wherein the bridge pillars are arranged on the lower parts of the beam bodies; the connecting beams are arranged between every two beam bodies; the connecting beams are provided with upright posts, and the upright posts are fastened and connected with the beam bodies through buckles. According to the utility model, a flexible connection system establishes connection relation between every two beam bodies, and therefore, beam falling damage caused by seism on a bridge can be effectively reduced; not only can longitudinal beam falling be prevented, but also latitudinal beam falling be prevented; displacements generated by the temperature, the elongation, and the like of a structure in a normal use state can be balanced, and additional longitudinal force and additional latitudinal force are not generated on the bridge structure; automatic resetting after the seism is achieved, and detection and replacement are easy to carry out.
Description
Technical field
The utility model relates to the bridge technology field, especially relates to the anti-fall beam construction of a kind of antidetonation connecting rod.
Background technology
At present, the Bridges in Our Country seismic design mainly is to stress the intensity of pier body, and the pier body is not collapsed in earthquake.The anti-fall beam construction of being adopted mainly is on the pier body, to fixedly install beam falling prevention stopping block, is controlled in certain scope with lateral displacement amount and length travel amount with the beam body.But, get in touch owing to lack between beam body and pier body, beam body and the beam body, when the higher earthquake of earthquake intensity is attacked, the impact that acutely rocked by the beam body, beam falling prevention stopping block is prone to shear failure takes place and lost efficacy, and produces beam and destroys.
Along with developing rapidly of China's transport development cause, bridge quantitatively still is all in quick growth on the development length as the multi-purpose project in the traffic lines.And China is an earthquake pilosity country, and bridge will make whole transportation network paralyse in case the beam that in earthquake, falls destroys, serious obstruction rescue and rebuilding in disaster-hit areas.
The appearance of therefore, a kind of easy construction, the anti-fall beam construction of antidetonation connecting rod that anti-seismic performance is strong is necessary.
The utility model content
To above-mentioned deficiency, the purpose of the utility model is to provide a kind of easy construction, the anti-fall beam construction of a kind of antidetonation connecting rod that anti-seismic performance is strong.
The technical problem that the utility model solved adopts following technical scheme to realize:
The anti-fall beam construction of a kind of antidetonation connecting rod; Comprise the beam body, be arranged at the bridge post of said beam body bottom and be arranged at the tie-beam between said beam body and the beam body; Wherein, on said tie-beam, be provided with column, said column and said beam body are solidly connected through the button chucking.
The beneficial effect of the utility model is: flexible connection body ties up to set up to be connected between beam body and the beam body and gets in touch, so can reduce earthquake effectively the beam that falls that bridge causes is destroyed; Both the beam that vertically falls can be prevented, the beam that laterally falls can be prevented again; The displacement that the temperature elongation of structure etc. is produced under can the balance normal operating condition does not produce additional longitudinal force and additional lateral power to bridge construction; Can be easy to inspection and change from horizontal reset after the shake.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure, 1, the beam body, 2, the bridge post, 3, tie-beam, 4, column, 5, the button card.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
With reference to shown in Figure 1; The anti-fall beam construction of a kind of antidetonation connecting rod; Comprise beam body 1, be arranged at the bridge post 2 of said beam body 1 bottom and be arranged at the tie-beam 3 between said beam body 1 and the beam body 1; Wherein, on said tie-beam 3, be provided with column 4, said column 4 is fastenedly connected through button card 5 with said beam body 1.
The utility model ties up to set up to be connected between beam body 1 and the beam body 1 through flexible connection body and gets in touch, so can reduce earthquake effectively the beam that falls that bridge causes is destroyed; Both the beam that vertically falls can be prevented, the beam that laterally falls can be prevented again; The displacement that the temperature elongation of structure etc. is produced under can the balance normal operating condition does not produce additional longitudinal force and additional lateral power to bridge construction; Can be easy to inspection and change from horizontal reset after the shake.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the manual that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
