Furthermore, the side span concrete bridge section supporting structure comprises square timbers arranged on the I-shaped steel and square timbers mixed supporting structure.
Further, the pier stud counterweight structure comprises a triangular counterweight steel bracket arranged on the side wall of the side-span pier stud.
Further, pier stud counter weight structure is including setting up the sand bag counter weight on triangle counter weight steel bracket.
The utility model has the advantages that: in actual use, because the closure construction needs to be completed between the side span concrete bridge section and the bridge suspension casting section, the side span concrete bridge section needs to be obtained by formwork erection and cast-in-place construction on the side span pier column. When the side-span concrete bridge section is cast and constructed on the side-span concrete bridge section, the pier column counterweight structure is arranged on the side-span concrete bridge section, so that the side-span concrete bridge section is prevented from being bent due to construction, and the overall safety of the side-span concrete bridge section is ensured. The scheme greatly improves the efficiency of folding construction, and is particularly suitable for folding construction of bridge side spans.
Drawings
Fig. 1 is an overall schematic view of the construction site of the present invention.
Fig. 2 is a schematic structural diagram of the present invention.
Labeled as: the bridge comprises a side-span bridge pier column 1, a side-span concrete bridge section 2, a suspension casting section 3, a bridge pier column 4, a triangular bridge steel bracket 5, a transverse force bearing I-shaped steel 6, a square timber 7, an I-shaped steel and square timber mixed supporting structure 8, a counterweight sand bag 9, a triangular counterweight steel bracket 10 and a closure section 11.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1, 2 bridge sidespan construction structures, including the side bridge pier stud 1 with set up in pier stud 4 of side bridge pier stud 1 one side, including the side bridge concrete bridge section 2, be close to pier stud 4 one side on the side bridge pier stud 1 and be provided with the side bridge concrete bridge section bearing structure, keep away from pier stud 4 one side on the side bridge pier stud 1 and be provided with the pier stud counter weight structure, the side bridge concrete bridge section 2 sets up on the side bridge concrete bridge section bearing structure. The scheme solves the problem that a great amount of consumable materials of the steel trestle is installed on the river surface of the bridge side span in the conventional mode, and then the scaffold is erected to be connected with the high-difficulty operation of the bridge bottom formwork, so that the aims of low construction difficulty, short construction period, low cost and high safety are fulfilled.
In order to further simplify the side-span concrete bridge section supporting structure on the premise of ensuring the supporting effect, the side-span concrete bridge section supporting structure preferably comprises a triangular bridge steel bracket 5 arranged on the side wall of the side-span pier stud 1. As shown in fig. 1, the triangular bridge steel bracket 5 is arranged on the side wall of the side-span pier stud 1, and then, a transverse bearing i-shaped steel 6 can be further arranged on the triangular bridge steel bracket 5. Further selecting to arrange an I-steel and square wood mixed supporting structure 8 on the transverse bearing I-steel 6 and further arranging a square wood 7 on the I-steel and square wood mixed supporting structure 8. The parts arranged on the triangular bridge steel bracket 5 can effectively realize the distribution of stress when the side span concrete bridge section 2 is poured, and the overall safety is ensured.
Similarly, the pier stud counterweight structure may optionally include a triangular counterweight steel bracket 10 that straddles the side wall of the pier stud 1.
