Integrated support pier bracket tool system for eccentric half-range steel-concrete combined box girder

Abstract

The invention relates to an integrated support pier bracket tool system for an eccentric half-range steel-concrete combined box girder, the system can reliably support, transport and hoist the eccentric half-range steel-concrete combined box girder with the length of 32.25 m, the width of 17.8 m and the weight of more than 539 tons. The integrated support pier bracket tool system comprises a support frame which is in intermittent welding connection with an inclined bottom plate of the eccentric half-range steel-concrete combined girder, and steel supporting piers connected with the flat bottom plate of the eccentric half-range steel-concrete composite girder, each support frame stretches across two or three transverse partition plates, and the four steel support piers are integrated under the box girder partition plates in a bolted mode. The gap between the leveling plate at the bottom of the support frame and the top plate of the steel support pier is controlled by adjusting the bolting bolts, and the height of the support beam section is adjusted by adding the adjusting base plate so that the purpose of ensuring uniform stress of each supporting point in the supporting process is achieved. The system has the advantages that the stability of the eccentric half-range steel-concrete combined box girder with the length of 32.25 m, the width of 17.8 m and the weight of more than 539 tons during transportation, supporting and shipping in a factory is ensured, and the eccentric half-range steel-concrete combined box girder is smoothly mounted and erected.

Description

Technical field [0001] The present invention relates to an eccentric half-steel binder tooling system that can be reliably supported, transported, and lifted with an eccentric half-length steel blending assembly system that can be reliably supported, transported, hoisting, transported, and hoisting. Super Eccentric Semi-Ec Eccentric Semi-Steel Blend Complex Box Beam Supporting Manufacturing Field. Background technique [0002] The large eccentric half-raised steel blend box beam is a new structure, and there is currently no technical application of factory manufacturing. The super-eccentric half-sleeve blended combination beam, has the characteristics of high structural dimensions, heavy segment quality, structural eccentricity and structural size manufacturing precision, and the manufacturing is mainly manufactured: First, the structural size is long, the quality is overweight, the structure is eccentric, The segment manufacturing accuracy and high matching accuracy of adjacent ...

AI Technical Summary

Problems solved by technology

The super-large eccentric half-width steel-concrete composite beam has the characteristics of large structural size, heavy segmental mass, structural eccentricity and high manufacturing precision of structural size. Its manufacturing mainly has the following manufacturing problems: first, the structural size is too long, the quality is overweight, and the structure is eccentric. The manufacturing accuracy of the segment and the matching accuracy with the adjacent segment are high, and the accuracy control is the difficulty of manufacturing; the second is that the concrete prefabricated bridge deck is 30 to 50 tons, and the total splicing line has a large span. Generally, the lifting weight of a single hoisting crane It cannot meet the hoisting requirements, and the hoisting, assembly and superposition control of the concrete prefabricated bridge deck is a difficult point in manufacturing; the third is that the structural size is too long, the quality is overweight, the structure is eccentric, and how to produce the tire after the completion of the segment assembly is the manufacturing difficulty; Fourth, the transportation and support of the eccentric half-width steel-concrete composite box girder are difficult points in the manufacturing process; fifth, during the wet joint pouring construction process, ensure that the box mouth size of the finished product segment after pouring is consistent with the assembly It is a difficulty in the manufacturing process; Sixth, due to the over-length, over-weight, and eccentric structure, one of the difficulties that need to be considered in the manufacturing process is to ensure transportation safety and smooth hoisting of the segmental construction site during the loading and transportation of segments
