BL-5519 LU502338
TECHNICAL FIELD The present invention belongs to the technical field of bridge engineering, and particularly relates to a suspended bridge deck of a through type arch bridge reinforced by a stiffening longitudinal beam of atrussed steel structure and a construction method thereof.
BACKGROUND There have been many through type arch bridges constructed in China. The suspended bridge decks in early stage are not designed based on stiffening longitudinal beams but cross beams. Suspenders are also anchored to two ends of the cross beam, then a bridge deck slab 1s paved on the cross beams, and the stiffening longitudinal beams are not arranged among most cross beams. In the current stage, the suspended bridge decks of many through type arch bridges operated and used for several years have many diseases, for example, too large bridge deck vibration, severely damaged bridge decks, falling of supports and the like. In recent years, several accidents of bridge deck collapses and even collapses of the whole bridges due to accidental rupture of suspenders have happened successively, resulting in irreversible economical losses.
With occurrence of several major accidents of the through type arch bridges caused by damages of the suspended bridge decks and various diseases of various types, research scholar and designers 1
BL-5519 LU502338 attach importance to arrangement of stiffening longitudinal beams gradually. With respect to reinforcement of the suspended bridge decks of the through type arch bridges that have been used for many years, concrete stiffening longitudinal beams are additionally arranged for part of the suspended bridge decks. The concrete stiffening longitudinal beams are large in rigidity and good in vibration resistance, but increase the loads borne by the suspenders remarkably, and are difficultly constructed. Steel beams of profile steel structures are additionally arranged as the stiffening longitudinal beams for part of the suspended bridge decks. The integral stiffening longitudinal beams of steel structures, different from materials of the bridge decks of concrete structures, generate inconsistent deformations under influence of different temperatures, resulting in new disease problems such as displacement of the cross beams, cracking of concrete and falling of the supports.
Therefore, it is necessary to design a suspended bridge deck of a through type arch bridge reinforced by a stiffening longitudinal beam of a trussed steel structure and a construction method thereof, where the suspended bridge deck is light in self weight, large in rigidity, reasonable in structural stress, convenient to construct and excellent in durability, which can effectively solve the problem of insufficient overall rigidity and poor stability of the suspended bridge deck of the through type arch bridge, and can sufficiently release deformation, harmful to structural stress, of the stiffening longitudinal beam of the trussed steel structure due to temperature variation.
A Chinese utility model patent with the publication No. CN211571359U and the publication date: 25%, Sep., 2020 discloses a through type arch bridge enhancing transverse rigidity of a main beam 2
