Embodiment 1

[0045] like figure 1 and figure 2 As shown, compared with the connection structure of the traditional longitudinal girder and the cover beam, the hidden cover beam connection structure of this embodiment can make full use of the clearance height under the bridge and reduce the wiring length of the bridge. And the use of the stand can be omitted. Specifically, such as Figure 2-Figure 9 As shown, the concealed cover beam connection structure of the present embodiment includes the longitudinal beams 14 arranged adjacent to the longitudinal bridge and the concealed cover beams arranged on the pier 13, and the adjacent longitudinal beams 14 are connected by hidden cover beams, and the hidden cover beams include Cover beam steel top plate 1, cover beam steel bottom plate 2 and cover beam steel web 3 enclose a box structure, and cover beam steel web 3 is arranged between cover beam steel top plate 1 and cover beam steel bottom plate 2.

[0046] In this embodiment, the box struct...

Embodiment 2

[0056] like Figure 10-Figure 17 As shown, the concealed cover beam connection structure of the present embodiment includes the longitudinal beams 14 arranged adjacent to the longitudinal bridge and the concealed cover beams arranged on the pier 13, and the adjacent longitudinal beams 14 are connected by hidden cover beams, and the hidden cover beams include Cover beam steel top plate 1, cover beam steel bottom plate 2 and cover beam steel web 3 enclose a box structure, and cover beam steel web 3 is arranged between cover beam steel top plate 1 and cover beam steel bottom plate 2.

[0057] In this embodiment, the box structure is provided with a plurality of cover beam transverse partitions 5 arranged vertically along the longitudinal bridge direction and a plurality of inner chamber partitions 6 arranged horizontally. The longitudinal beam 14 includes a beam top plate 141, a beam web The position of the plate 143 and the beam bottom plate 142, the cover beam transverse partit...

Abstract

The invention discloses a hidden cover beam connecting structure which comprises longitudinal beams adjacently arranged in the longitudinal bridge direction and hidden cover beams arranged on bridge piers, the adjacent longitudinal beams are connected through the hidden cover beams, and each hidden cover beam comprises a cover beam steel top plate, a cover beam steel bottom plate and a bent beam steel web which define a box type structure. The bent beam steel web is arranged between the bent beam steel top plate and the bent beam steel bottom plate. According to the hidden cover beam connecting structure, the adjacent longitudinal beams are connected through the hidden cover beams, an existing conventional structure that the longitudinal beams are placed on the cover beams does not need to be adopted, the clearance height under a bridge can be fully utilized, the wiring length of the bridge is reduced, the use of a support can be omitted, and the trouble of replacement and maintenance is avoided.

Description

technical field [0001] The invention belongs to the field of bridges, in particular to a cover-beam connection structure. Background technique [0002] In recent years, with the acceleration of urbanization, in order to improve the efficiency of urban traffic, more and more urban viaducts have been built on the original urban arterial roads. In order to reduce the interference to road traffic and surrounding residents, prefabricated bridges with the goal of "factoryization, assembly, greening, and rapidity" are being applied to urban viaducts more and more. Steel plate composite girder bridges and steel box girder bridges are typical prefabricated bridges, which have the advantages of factory prefabrication, overall hoisting, and convenient and quick construction. [0003] In the traditional bridge form, several steel plate composite girders or steel box girders (longitudinal girders) are placed on the cover girders, bearings are placed between the longitudinal girders and ...
