specific Embodiment approach 1

[0037] Embodiment 1: The prefabricated corrugated steel-concrete top-supported bridge in this embodiment includes a corrugated steel-concrete arch 1, a plurality of columns 2 and a bridge deck 3, wherein the corrugated steel-concrete arch 1 is made of multi-section prefabricated corrugated steel - Concrete segments 4 are connected, and a column head 5 is arranged on the upper surface of part of the prefabricated corrugated steel-concrete segment 4 to form a prefabricated corrugated steel-concrete segment 6 containing the column head. The column 2 is erected on the column head 5, and the column 2 The bridge deck 3 is erected on the column top surface;

[0038] The prefabricated corrugated steel-concrete segment 4 is a single-layer corrugated steel-concrete structure or a double-layer corrugated steel-concrete structure, the single-layer corrugated steel-concrete structure is poured with concrete on the surface of the single-layer corrugated steel 7, and the double-layer corrugat...

specific Embodiment approach 2

[0040] Embodiment 2: This embodiment is different from Embodiment 1 in that the steel plate surface of the concrete poured on the corrugated steel 7 in the prefabricated corrugated steel-concrete segment 4 is uniformly provided with shear studs.

[0041]For the corrugated steel plate-concrete segment proposed in this embodiment, the corrugated steel plate needs to be welded with shear studs to increase the connection between the corrugated steel and the concrete, and prevent disengagement during the stress process, which affects the mechanical performance; During the assembly process, the connection of corrugated steel plates must meet the requirements of "Corrugated Steel Tubes (Plates) for Highway Culvert Passages" (JTT791-2010).

specific Embodiment approach 3

[0042] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the corrugated structure of the corrugated steel 7 in the prefabricated corrugated steel-concrete section 4 extends along the width direction of the bridge.

Abstract

The invention discloses a prefabricated corrugated steel-concrete deck type bridge and a construction method thereof, relates to a deck type bridge and a construction method thereof, and aims to solve the technical problems that an existing arch bridge structure is insufficient in bearing capacity and slow in cast-in-place construction. The deck type bridge comprises a corrugated steel-concrete arch body, a plurality of stand columns and a bridge deck slab, the corrugated steel-concrete arch body is formed by connecting a plurality of prefabricated corrugated steel-concrete sections, and column heads are arranged on the upper surfaces of part of the prefabricated corrugated steel-concrete sections to form the prefabricated corrugated steel-concrete sections with the column heads, and bridge deck slabs are erected on the top faces of the stand columns; the prefabricated corrugated steel-concrete sections are of a single-layer corrugated steel-concrete structure or a double-layer corrugated steel-concrete structure. The section is stable and high in bearing capacity, the possibility of local buckling of the corrugated steel section in the installation process is reduced, the corrugated steel plays a part of formwork role, formwork construction is reduced, and the construction speed is increased.

Description

technical field [0001] The invention relates to an overhead bridge and a construction method thereof. Background technique [0002] my country will focus on transforming urban development patterns, shaping urban features, improving urban environmental quality, focusing on innovating urban management services, vigorously promoting prefabricated buildings, and increasing policy support. The ratio reaches 30%. Therefore, the use of prefabricated buildings will be the trend of social development. [0003] The application history of corrugated steel structure can be traced back to the end of the 19th century. In 1892, W.Q.O'Neill bought out the patent of corrugated steel pipes. Coupled with the rapid development of the steel industry at that time, corrugated steel pipes began to be widely used all over the world. The domestic research and application of corrugated steel bridges and culverts are relatively late. It first appeared before liberation and was mainly used in water c...
