Description

A kind of for improving the spring support top ruggedized construction of bridge shear resistance

Technical field

The utility model relates to Technology Bridge Strengthening field, is specially a kind of for improving the spring support top ruggedized construction of bridge shear resistance.

Background technology

In recent years, along with expanding economy, the quickening of urbanization process, much be built in Urban Bridge and the bridges in highway engineering of last century eight, the nineties, due to fatigue, External Force Acting or other many reasons, occurred damage in various degree, there is potential safety hazard, not only costlyly have a strong impact on especially traffic if remove to rebuild, in this case, selecting it to carry out targetedly consolidation process is a kind of good footpath.

Existing Technology Bridge Strengthening is mainly divided into two classes, for a change structural system of a class, as reduce the span of beam, simply supported beam changes beam structure into, to alleviate former beam burden as object; An other class, enlarging section size and reinforcement structural reinforcement etc.Current reinforcing technique adopts tensile region to paste the reinforcement measures such as charcoal fiber, steel plate mostly, and these reinforcement means belong to passive reinforcing category from principle.Member dead weight and dead load are carried on a shoulder pole by former joist support, mobile load is born by reinforcing later compound section, after add supporting material intensity be subject to the restriction of former beam distortion, generally in the time of ultimate limit state, its stress does not reach tensile strength design load, have great wasting phenomenon, it is very limited that simultaneously reinforcement material only solves its consolidation effect of problem of mobile load.In recent years, the active reinforcement measure that embodies advanced design theory gets the nod gradually, the active of bridge construction is reinforced, the external prestressing tendons that adopt more, or the method for bonded prestress steel Shu Jiagu, changes the distribution of internal force, and it has fundamentally solved the problem that rear supporting material stress lags behind, give full play to mechanical properties of materials, improved the utilization ratio of material.

There are equally some problems in above-mentioned prestressing force initiatively reinforcement bridge technology.For the bridge strengthening that can not suspend traffic, bridge lower prestress complicated construction technique arranges anchor measure on damaged bridge, and the bridge for the treatment of reinforcing causes further infringement.Due to the damaed cordition complexity of prestressed strand, after having reinforced, the very difficult monitoring of the effective prestressing effect theoretical analysis and calculation that adopt obtain more, have certain deviation with actual conditions, are not easy to the bridge force-bearing state of Guan Yang unit's grasp reinforcing etc.When strengthening construction, adopt interrupted or restricting traffic measure more, or further strengthens the measure etc. of prestressing effect, brings inconvenience to engineering.
