Problems solved by technology
This construction method can ensure the accuracy of steel box hoisting and improve construction safety to a certain extent, but the actual operation is more complicated and does not involve construction techniques such as concrete pouring quality control
[0004] In summary, the existing construction methods have achieved good results in suitable working conditions, but further research is needed to improve the integrity of construction structures and ensure the quality of concrete pouring.

The invention relates to a construction method of a steel box-concrete combined beam hoisting system. The construction method comprises the following steps of 1) construction preparation, 2) construction support arrangement, 3) steel box splicing construction, 4) concrete pouring construction and 5) prestress cable bundle tensioning construction. The construction support has the beneficial effectsthat the construction support is convenient to install on site, the integrality is good, the construction time of a concrete foundation site is shortened, and the difficulty of mounting and positioning of a transverse bailey beam is effectively reduced; meanwhile, a beam-side guardrail and the transverse bailey beam are convenient to mount and connect, and the mounting cost of the guardrail can be saved; the steel box is high in mounting and positioning precision and easy to displace, the fastening force can be exerted to the steel box through a beam top clamping plate, and the welding construction difficulty is reduced; and meanwhile, an adjustable inner support is arranged inside the steel box, so that not only the integrality of the steel box can be improved, but also the utilization rate of materials can be improved.
Description
technical field [0001] The invention relates to a construction method for a steel box-concrete composite beam hoisting system that improves the integrity of construction structures, reduces the difficulty of hoisting and positioning steel box girders, improves the quality of concrete pouring, and improves the construction quality of prestressed cable bundles, and belongs to bridge engineering It is suitable for steel box-concrete composite beam construction projects. Background technique [0002] The steel box-concrete composite beam is a new type of composite cross-section beam that combines the characteristics of composite composite beams and steel tube concrete. The method obtains faster construction progress and realizes economic and technical advantages. In the construction practice of steel box-concrete composite beams, ensuring the hoisting construction accuracy of steel boxes and the pouring quality of concrete has become the main technical point to be solved by eng...
