Embodiment Construction

[0060] Such as figure 1 and figure 2 A cable-beam composite bridge shown includes a plurality of bridge segments arranged from front to back along the longitudinal direction of the bridge. The structures of the plurality of bridge segments are the same, and each of the bridge segments is It includes a beam structure 1 laid on the pier of the constructed bridge, a pavement layer laid on the beam structure 1 and a steel cable structure 2 arranged at the bottom of the beam structure 1;

[0061] Described beam body structure 1 comprises the multi-column longitudinal beam 1-1 that lays from left to right along the transverse width direction of the bridge pier of construction, and multi-column described longitudinal beam 1-1 is all arranged on the same horizontal plane, and each row described The longitudinal beams 1-1 all include a plurality of longitudinal beam segments 1-2 arranged on the same horizontal plane from front to back along the longitudinal length direction of the br...

Abstract

The invention discloses a cable-girder combined type bridge and a construction method thereof. The cable-girder combined type bridge comprises a plurality of bridge sections, each bridge section comprises a girder body structure, a pavement layer and a cable structure, the girder body structure comprises a plurality of columns of longitudinal beams, and the cable structure comprises a cable and stay bars. The construction method is characterized in that the bridge is constructed in bridge sections from front to the back along the longitudinal direction of the bridge, construction methods on the bridge sections are the same, and the construction process of each bridge section includes the steps of 1), construction of the first bridge section includes: 101, construction of the girder body structure, 102, mounting of the cable structure, and 103, pavement of the bridge floor; 2), construction of the next bridge section; 3), multiple repeat of the step 2) till all the construction process of the constructed bridge is completed. All the girder structure is under pressure, the cable is under tension, the cross section and self weight of the girder body structure are reduced, bending moment of the girder body structure is reduced, and spanning capability is increased.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a cable-beam combined bridge and a construction method thereof. Background technique [0002] Reinforced concrete girder bridges are the main structural form of medium and small span bridges at present. The beam bridge is mainly a bridge mainly subjected to bending, and the girder body of the beam bridge has both compression areas and tension areas. The concrete material has high compressive strength. By configuring ordinary steel bars or prestressed steel beams for the concrete, the girder bridge can give full play to the compressive capacity of the concrete and the tensile capacity of the steel bars or steel beams, and has good economic performance. When the span of the beam bridge increases, because the bending moment of the beam body is proportional to the square of the span of the beam body, the bending moment of the beam body will increase rapidly. ...
