Embodiment 1
[0044] Such as Figure 4~6 As shown, a deviation monitoring system for a double-span synchronous tensioning bridge erecting machine is applied to a support main girder 21, an up and down moving body 22, two sets of guide wheels 23, and a shaft height adjustment structure 24 corresponding to the guide wheels 23. The deviation monitoring of the bridge erecting machine 2, wherein the supporting main beam 21 is supported and fixed by the feet, the vertical moving body 22 is moved up and down relative to the supporting main beam 21, and the two sets of guide wheels 23 are symmetrical along the transverse bridge direction at the top of the supporting main beam 21 set, and the guide height adjustment is realized through the shaft height adjustment structure 24, a number of first slings 5 are arranged at the bottom of the up and down moving body 22, and a number of second slings 6 are arranged at the top, and the second sling 6 is set on one of the guides. The wheel 23 is drawn out ...
Embodiment 2
[0051] The construction method of the steel-concrete composite bridge adopts the deviation monitoring system of the double-span synchronous tension bridge erecting machine as described in the first embodiment, including:
[0052] Step 1: Prefabricate the steel beam module 1 to form a channel structure including the bottom plate 11 and two flange plates 12 on both sides, connect the tops of the two flange plates 12 through a number of steel bar components 13, and set the ring structure 14 in the middle of the steel bar components 13 ;
[0053] Such as Figure 1~3 As shown, the steel beam module 1 adopted in the present invention is shown, wherein the structure including the bottom plate 11 and the flange plate 12 is an integrally formed structure, and the reinforcement component 13 is an additionally installed structure.
[0054] The second step: make the bridge erecting machine 2 advance to the position of the first span and the second span, and the second span is located on ...
Embodiment 3
[0074] The construction method of the steel-concrete composite bridge adopts the deviation monitoring system of the double-span synchronous tension bridge erecting machine as described in the first embodiment, including:
[0075]Step 1: Prefabricate the steel beam module 1 to form a channel structure including the bottom plate 11 and two flange plates 12 on both sides, connect the tops of the two flange plates 12 through a number of steel bar components 13, and set the ring structure 14 in the middle of the steel bar components 13 ;
[0076] The second step: make the bridge erecting machine 2 advance to the position of the first span and the second span, and the second span is located on the side of the subsequent construction; the side of the supporting main beam 21 of the bridge erecting machine 2 is set at the position corresponding to the first span There are up and down moving bodies 22 and corresponding guide structures, and a set of guide wheels 23 and corresponding sha...
