Background
With the popularization of the bridge prefabrication and assembly construction process in bridge construction, a large number of prefabricated bent caps need to be hoisted in the construction process, but the bent caps prefabricated in sections only have one supporting point of the upright post and cannot maintain self-stability, so that temporary support needs to be applied. However, the consumption of temporary supports required by the existing cast capping beam is large, the turnover is slow, the cost is high, the time and the labor are consumed in the laying process, and the traffic of a construction area can be influenced after the temporary supports are laid. The above-mentioned drawbacks have resulted in the fact that the existing temporary supports cannot be applied on a large scale to temporary structures for prefabricated capping beams. In addition, there is also difficulty in accurately adjusting the attitude of the capping beam during hoisting of the precast capping beam.

Detailed Description
The features of the present invention and other related features are described in further detail below by way of example with reference to the accompanying drawings, for the understanding of those skilled in the art:
referring to fig. 1-3, the symbols in the figures are: the device comprises prefabricated upright columns 1, thickened brackets 2, steel cross beams 3, steel longitudinal beams 4, prefabricated capping beams 5, jacks 6, an operating platform 7, sand drums 8, bolt prefabricated holes 9 and high-strength bolts 10.
Example (b): as shown in fig. 1 to 3, the present embodiment relates to a suspended support of a segment precast capping beam, and provides an effective support for a precast capping beam 5 by arranging a steel longitudinal beam 4 and a steel transverse beam 3 on a precast upright post 1.
As shown in fig. 1-3, the suspension support of the segment prefabricated capping beam in this embodiment is disposed on the prefabricated vertical column 1, the suspension support includes two sets of steel beams 3 and two sets of steel longitudinal beams 4, thickened brackets 2 are disposed on two sides of the prefabricated vertical column 1 along the bridge direction, the steel beams 3 are disposed on the thickened brackets 2 on two sides of the prefabricated vertical column 1, the steel longitudinal beams 4 are spanned between the two sets of steel beams 3, the steel longitudinal beams 4 are disposed outside two sides of the prefabricated vertical column 1, and a plurality of jacks 6 are disposed on the upper surface of each steel beam 3. The suspended support frame of the embodiment is arranged on a support unit provided with two prefabricated upright posts 1, and the segment prefabricated capping beam 5 is placed on a jack 6. Two symmetrical segmental prefabricated capping beams 5 are required to be arranged on each supporting unit, and each capping beam corresponds to one prefabricated upright post 1. Each capping beam is provided with two support points, which are respectively the jack 6 on the steel longitudinal beam 4 and the prefabricated upright 1.
In this embodiment, prefabricated hole 9 of bolt all is provided with in the same direction as bridge in prefabricated stand 1 top, and thickening bracket 2 is connected with prefabricated hole 9 of bolt through high strength bolt 10, and foretell prefabricated hole 9 of bolt sets up when the prefabricated stand construction is pour. The steel beam 3 is connected with the thickening bracket 2 through bolts. The steel cross beam 3 is connected with the steel longitudinal beam 4 through bolts. The bolt connection adopts high-strength bolts, so that the installation and the disassembly of the suspended support are simpler and more convenient. The upper portion of thickening bracket 2 bears steel crossbeam 3 and 4 pressures of steel longeron, gives high strength bolt 10 with pressure transmission again, and on the pressure transmission stand that high strength bolt 10 will bear again, whole unsettled support finally maintains stability through the support of prefabricated stand 1, and the setting process of the ground under traditional support basis has been saved to foretell biography power structure.
In this embodiment, an operation platform 7 is arranged between adjacent prefabricated vertical columns 1, and the operation platform 7 is arranged on the steel beam 3. A sand bucket 8 is also arranged between the steel longitudinal beam 4 and the segment precast capping beam 5. The steel cross beam 3 and the steel longitudinal beam 4 not only provide a fulcrum for the hanging end of the prefabricated bent cap 5, but also provide a template support and an operation platform 7 for high-altitude safe maintenance for the construction of the cast-in-place section of the prefabricated bent cap 5, thereby providing convenience for the whole process of the construction of the section prefabricated bent cap 5. The sand bucket 8 can supplement the support of the steel longitudinal beam 4 to the segment precast capping beam 5.
In this embodiment, jack 6 is located the free end bottom of prefabricated bent cap 5, and through jack 6's on the steel longeron 4 jacking and decline, the elevation of the regulation bent cap that can be accurate fast has reduced the safety risk and the quality risk of hoist and mount process.
The embodiment has the following advantages: the structure is simple, the safety and the practicability are realized, and the material consumption is less; the dismouting is convenient, and the subassembly can reuse, and the high ground traffic influence of unsettled support is little, can carry out accurate adjustment to the gesture of prefabricated bent cap 5.
