The utility model is realized by the following technical scheme:
a large-span single rib upper supporting arch structure bridge for suspension type monorail which characterized in that: including pier stud, arch rib, end crossbeam, track walking roof beam, well crossbeam, wherein the end crossbeam supports the capital of pier stud, the track walking roof beam set up the cross-bridge of end crossbeam to both sides and with end crossbeam fixed connection, two the interval arrangement has between the track walking roof beam well crossbeam, the arch rib sets up the below of well crossbeam and between them through a plurality of steel stand fixed connection.
And parallel connection is arranged between the two track walking beams.
The parallel connection and the track walking beam are connected through bolts to form a whole.
And two ends of the arch rib are welded with the end cross beam.
The middle cross beam and the track walking beam are connected through bolts to form a whole.
The pier column is of a combined structure of a steel box section and a concrete section, and the pier tops of the pier column are of steel structures within a certain range.
The track walking beam adopts a U-shaped steel section track beam.
The utility model has the advantages that: the suspension type single-rail beam with large crossing capacity, good landscape effect and rich cultural connotation meets the requirements of scenic spots and parks on a large-span landscape track beam bridge; the vertical rigidity of the bridge span is improved, and the transverse stability and the comfort of the travelling crane are ensured; simple structure is reasonable, and construction is convenient, and the efficiency of construction is high, is suitable for the popularization.

Detailed Description
The features of the utility model and other related features are described in further detail below by way of example in conjunction with the following figures to facilitate understanding by those skilled in the art:
as shown in fig. 1-4, reference numerals 1-8 are respectively represented as: arch rib 1, pier stud 2, steel upright post 3, middle cross beam 4, end cross beam 5, parallel connection 6, arch foot 7, track walking beam 8.
Examples: as shown in fig. 1 to 4, the large-span single-rib upper-bearing arch bridge for suspension monorail in this embodiment is used as a double-line suspension monorail bridge that can be erected in scenic spots, gardens and other places, and is mainly used in areas such as ancient buildings, protection areas, landscape lakes and the like in cross-regions.
As shown in fig. 1 to 4, the structural bridge main body comprises pier columns 2 at two sides, and bearing platforms and corresponding foundations are arranged at the bottoms of the pier columns 2 at two sides so as to ensure structural stability of the pier columns 2. An end cross beam 5 is arranged above the pier column 2, and the end cross beam 5 is fixedly connected with the pier column 2. Rail running beams 8 are provided on both sides of the end cross beam 5, respectively, to form a double line structure. A plurality of middle cross beams 4 which are uniformly arranged at intervals along the running direction are arranged between the track running beams 8 at the two sides so as to connect the track running beams 8 at the two sides to form an integral structure; meanwhile, parallel links 6 which are arranged in a crossing way are further arranged between the track walking beams 8 in the area between the middle cross beams 4, so that the connection strength between the two track walking beams 8 is further improved, and the integrity is ensured.
Below the track running beam 8, a rib 1 is provided, which rib 1 is a single rib. Steel upright posts 3 are arranged between each middle cross beam 4 and each arch rib 1, and the arch ribs 1 and the middle cross beams 4 can be connected into an integral structure through the arrangement of the steel upright posts 3; while the two ends of the arch rib 1 are fixedly connected with the end cross beam 5.
In this embodiment, the arch rib 1 belongs to a tension member, and adopts a wide box section, stiffening ribs can be arranged along the longitudinal direction of the arch rib, and vertical stiffening ribs are arranged on the circumference of each steel upright 3 for the arch rib 1 so as to counteract the warping of the steel plate caused by overlarge local compression.
The embodiment is implemented in specific manner: the arch rib 1 adopts a box-shaped section, and the arch foot 7 and the end cross beam 5 are welded and fixed. The end cross beam 5 adopts a box-shaped cross section. The middle cross beam 4 adopts a box-shaped section, and is welded and fixed with the steel upright post 3 and the track walking beam 8.
The pier column 2 is a combined structure of a steel box section and a concrete section, and the pier top of the pier column is of a steel structure within a certain range, so that the pier column can be quickly assembled with the end cross beam 5 above the pier column through measures such as high-strength bolts or welding. The lower structure of the pier column 2 can adopt a high-strength concrete structure, the concrete is a prefabricated component, and the longitudinal stability and the transverse stability of the pier are improved through connection between the embedded component and the steel structure on the upper part of the pier column 2.
Although the foregoing embodiments have been described in some detail with reference to the accompanying drawings, it will be appreciated by those skilled in the art that various modifications and changes may be made thereto without departing from the scope of the utility model as defined in the appended claims, and thus are not repeated herein.
