Abstract
The utility model relates to a novel temporary support used in bridge construction. The temporary support comprises a lower bearing block, an unloading layer and an upper bearing block, wherein the lower bearing block, the unloading layer and the upper bearing block are stacked in sequence. Liquid materials or solid materials prone to being melted and softened after the solid materials are heated and filled to form the unloading layer, and steel plate layers and rubber blocks are stacked and sticked to form the upper bearing block and the lower bearing block in an intersecting mode. The topmost steel plate of the lower bearing block extends all around and bends upwards to form a spacing side wall provided with a diversion bottom outlet. The temporary support is compressible to certain extent, and therefore overcomes the defects that a traditional temporary support cannot enable a load on a permanent support to gradually increase with the promotion of construction progress and increase of the load of a beam body, while the permanent support compresses and sinks since the permanent support bears the load, and fails to gradually and fully explore a supporting role. The novel temporary support used in the bridge construction also overcomes the defect that the traditional temporary support is disposable, cannot be reused, and the defect of waste of time and energy to remove the temporary support, and therefore can be broadly applied to the bridge construction.
