Embodiment Construction

[0031] The following descriptions are only preferred embodiments of the present invention, and do not limit the scope of the present invention.

[0032] Example: as attached figure 1 , 2 , 3, 4, 5 and attached Figure 6 As shown, the under-supported arch bridge suspension bridge system reinforced with truss-type steel structure stiffened longitudinal beams includes an abutment 11, a corbel 12 arranged on the abutment 11, and a support arranged on the corbel 12. The seat 13, the suspender 14, and the bridge deck 15 also include the truss-type steel structure stiffening girders 1 arranged on the support 13, and the truss-type steel structure stiffening girders 1 arranged between adjacent The suspenders 14 are installed at both ends and are used to support the concrete beams 2 of the bridge deck 15 .

[0033] In this embodiment, a concrete crossbeam 2 is arranged between several stiffened longitudinal girders of the truss type steel structure 1, and the concrete crossbeam 2 di...

Abstract

The invention belongs to the technical field of bridge engineering, and particularly relates to a through arch bridge suspension bridge system reinforced by truss type steel structure stiffening longitudinal beams and a construction method thereof. By arranging the brackets, the supports, the suspenders, the bridge deck slabs, the truss type steel structure stiffening longitudinal beams and the concrete cross beams on an arch support, the effect of effective use of the through arch bridge suspension bridge system is achieved. The integral through type supporting structure comprising the truss type steel structure stiffening longitudinal beams and the concrete cross beams is high in integral rigidity and good in stability, the truss type steel structure stiffening longitudinal beams are light in dead weight, high in flexural rigidity and easy to construct, deformation, unfavorable for structural stress, of the integral through type supporting structure due to temperature changes is small. The method has the advantage of being good in overall reinforcing effect on the whole suspension bridge road system, and has great application value and good economic benefits.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, and in particular relates to a suspension bridge track system of an under-supported arch bridge reinforced by a truss-type steel structure stiffening longitudinal girder and a construction method thereof. Background technique [0002] my country has built many under-supported arch bridges. The road system design of early suspension bridges was not based on the stress of the stiffened longitudinal beam, but on the beam. The suspenders were also anchored at both ends of the beam, and then laid on the beam. For the bridge deck, there is no stiffening longitudinal girder between most of the beams. At this stage, after several years of operation and use of many under-supported arch bridges, many diseases have appeared in the suspension bridge system, such as excessive vibration of the bridge deck, serious damage of the bridge deck, and falling off of the supports. Serious accidents caused b...
