Embodiment 1

[0022] Such as figure 2 , image 3 As shown, an arch bridge support tool for increasing the construction stability of an arch bridge includes an angle steel 1 and at least two connecting rods 2 . The structure of angle steel 1 is as follows figure 1 shown. The angle steel 1 is preferably an equilateral angle steel, the specification of the angle steel used in this embodiment is ∠50×50×3, and the length is 1 meter. Of course, angle steels of other specifications can be used as required, and the length can also be adjusted. The length of the angle steel 1 is preferably 0.8-1.5 meters.

[0023] The connecting rod 2 is a threaded steel bar, such as image 3 As shown, during construction, the connecting rod 2 (threaded steel bar) is horizontally fixed on the main girder 4 of the arch bridge, and there is a certain distance between the two connecting rods 2, so that the angle steel 1 can be stably supported as a standard.

[0024] The edge of one side of the angle steel 1 is w...

Abstract

The invention discloses an arch bridge supporting tool for improving arch bridge construction stability and a construction method thereof, belonging to the field of municipal construction. The arch bridge supporting tool disclosed by the invention comprises angle steel and at least two connecting rods horizontally fixed on an arch bridge main beam, wherein one side of the angle steel is perpendicular to the connecting rods and is fixedly connected with the connecting rod; and a horizontal forced plane used for supporting the arch is formed on the other side of the angle steel. The arch bridge supporting tool disclosed by the invention provides a stress plane for an arch bridge plate supporting system, and the condition that a stressed plane of scaffolding steel pipes (arches) is suspended is avoided; and moreover, in the arch bridge construction process, when the arch is constructed on the beam plate on the upper part of a web arch, the arch vertical rod is erected on the angle steel plane to form a lower stressed plane, and the upper load can be vertically transferred to the arch bridge main beam. The arch bridge supporting tool disclosed by the invention is simple in structure, convenient to operate, low in cost and high in construction efficiency, the stress stability of the arch can be greatly improved, and the construction safety is guaranteed.

Description

technical field [0001] The invention relates to the field of municipal construction, in particular to an arch bridge support tool and a construction method for increasing the construction stability of an arch bridge. Background technique [0002] During the construction of the arch bridge, due to the curvature of the arch bridge girder and the continuously changing slope, the support (arch frame) of the upper girder slab of the abdominal arch has no stress plane, which has a great influence on the stability of the arch bridge slab support system. [0003] The prior art has not disclosed any technical solutions to the above problems, which is not conducive to the construction stability of the arch bridge. Contents of the invention [0004] In order to make up for the deficiencies of the prior art, the invention provides an arch bridge support tool and a construction method for increasing the construction stability of the arch bridge. [0005] Technical scheme of the presen...
