Embodiment 1

[0053] The first embodiment of the present invention provides a bent frame device of a multi-layer bridge structure, which is suitable for figure 1 The multi-layer bridge structure shown is a four-layer structure from top to bottom: the first layer is a special-shaped box girder structure, roughly in the shape of a cross, connecting vehicles in four directions, and the structure is the current Pouring prestressed reinforced concrete structure, pier columns are set under the four corners of the special-shaped box girder structure, numbered respectively B1P10, B1P8, B2-1P6, B2-2P0, and B1P9 pier columns are set in the middle of the special-shaped box girder structure; B1P8 piers The column is located on the east side of the special-shaped box girder, connecting the vehicles on the east side bridge with the special-shaped box girder; the B1P10 pier column is located on the west side of the special-shaped box girder, connecting the vehicles of the west bridge with the special-shaped ...

Embodiment 2

[0070] In the middle of the main line bridge, there is a three-story bridge structure (such as a station, an exhibition hall, a theater, etc.), and a special-shaped box girder needs to be set above the building structure to connect vehicles in four directions. Compared with the applicable situation of the first embodiment, there is no S2 ramp bridge that is connected to the main line bridge. In this case, the second embodiment is adopted. The difference between the second embodiment and the first embodiment is that the second embodiment no longer includes the full bowl buckle rack arranged at the bottom of the ramp, and the rest are the same as those of the first embodiment, which will not be described in detail here.

Embodiment 3

[0072] For a three-layer bridge structure in which there is an intermediate building structure (such as a station, an exhibition hall, a theater, etc.) in the middle of the main line bridge, and a special-shaped box girder needs to be set above the building structure to connect vehicles in four directions, the present invention also provides a The cross construction method of multi-layer bridge structure, the construction process is as follows Figure 4 As shown, including the following steps:

[0073] In step S101, the main line bridge box girder is erected, and the main line bridge deck concrete paving is performed based on the main line bridge box girder.

[0074] After the prefabricated main line bridge box girder is transported to the construction site, it is first erected; then the main line bridge deck concrete paving is carried out based on the main line bridge box girder.

[0075] Step S102, the construction of the B1P9 pier at the center of the special-shaped box beam.

Abstract

The invention relates to a multi-layer bridge structure framed bent device and a crossed construction method. A connection pier full bowl buckle framed bent is set up at the position of a special-shaped box girder connection pier stud; a bailey beam middle support top bowl buckle framed bent and a door opening bowl buckle framed bent are set up on two bridge floors of a main bridge respectively; the two sides of each bridge floor of the bottom of the main bridge are each provided with a steel pipe column support, a bailey beam in the bridge direction is connected to the upper portion of the steel pipe column support, and a bailey bridge stretching over the bridge transverse direction is arranged above the bailey beam in the bridge direction; a beam bottom support is arranged on the bailey beam in the bridge transverse direction is connected with a special-shaped box beam bottom formwork, a middle building is omitted, and the requirement for the bearing capacity and stability of the whole framed bent is met, so that the construction safety and construction schedule are ensured; according to different positions, corresponding framed bents are arranged, so that the construction cost is saved; meanwhile, by arranging the door opening bowl buckle framed bent on the main bridge, the requirement for smooth traffic can be met.

Description

Technical field [0001] The invention relates to the technical field of civil engineering construction, in particular to a cross construction technology for multi-layer bridge structures. Background technique [0002] With the progress of society, the transportation network is also growing. Due to the limited space, more and more layers and heights of bridge structures have been designed. In the construction process of multi-layer bridge structures, the selection of the concrete bent form and the placement position for supporting the bridge structure are particularly important, which will directly affect the construction safety, construction progress, construction cost, and smooth traffic of the multi-layer bridge structure. Wait. [0003] For the multi-storey bridge structure where there are building structures (such as stations, exhibition halls, theaters, etc.) in the middle of the main line bridge, and special-shaped box girder needs to be set above the building structure to c...
