Embodiment Construction

[0023] The present invention will be described in detail below in combination with specific embodiments.

[0024] The invention relates to a large-span steel corrugated plate arch bridge reinforcement structure, comprising a steel corrugated plate 2 composed of spliced ​​single plates, a plurality of channel-shaped steel plates 1 adjacently arranged longitudinally above the steel corrugated plate 2, and a horizontal channel-shaped steel plate 1 The cross-section is in the shape of a "several" with the notch facing down. Both ends of each channel-shaped steel plate 1 are provided with channel-shaped steel plate fixing holes 8, which are fixed to two crests of the steel corrugated plate 2 by channel-shaped steel plate fixing bolts 5, with a wave crest in the middle. The ends of two adjacent channel-shaped steel plates 1 share the channel-shaped steel plate fixing bolts 5 .

[0025] Steel bars are arranged between the steel corrugated plate 2 and the channel steel plate 1 and co...

Abstract

The invention relates to a large-span steel corrugated plate arch bridge reinforcement structure. A large-span steel corrugated plate bridge has higher requirements for the thickness of a steel corrugated plate in the aspect of stress but is influenced by production processes, so that the maximum thickness only can reach 10 millimeters and cannot meet the requirements. The large-span steel corrugated plate arch bridge reinforcement structure provided by the invention comprises steel corrugated plates which are formed by splicing single plates, a plurality of adjacent grooved steel plates are longitudinally arranged on the steel corrugated plates, the cross sections of the grooved steel plates are in a shape like the Chinese character 'ji', and notches are downward; two ends of the grooved steel plates are fixed at the peaks of the steel corrugated plates; and steel bars are arranged between the steel corrugated plates and the grooved steel plates, and concrete is poured between the steel corrugated plates and the grooved steel plates. The reinforcement structure provided by the invention can feasibly improve the requirements of the steel corrugated plate arch bridge for stress, can overcome the defect of the existing production process, namely the problem of structure instability caused by thin steel corrugated pipes, can be suitable for steel corrugated plate assembly technology, and is simple in structure, low in manufacturing cost and convenient to operate by being connected with the steel corrugated plates by bolt screwing.

Description

technical field [0001] The invention belongs to the technical field of bridge reinforcement, and in particular relates to a reinforcement structure of a large-span steel corrugated plate arch bridge. Background technique [0002] The long-span steel corrugated plate arch bridge is a bridge form formed by connecting and assembling corrugated arc-shaped plates. It adopts a thin-shell steel corrugated plate structure instead of masonry masonry to disperse stress in the transverse and axial directions of bridges and culverts, so as to better adapt to foundation deformation and facilitate application in highway engineering. At present, steel corrugated plate structures are mostly used in highway culverts in China, and are rarely used in small-span bridges. The maximum spans are all less than 13 meters, and there is no application research on large-span steel corrugated plate bridges with a span greater than 13 meters. [0003] When designing a long-span steel corrugated slab bri...
