Abstract

The invention provides a novel steel pipe truss composite beam bridge, and relates to a bridge adopting steel pipe truss composite beams. The steel pipe truss is an inverted triangular truss composed of a lower steel pipe 1, two upper steel pipes 2, spatial steel pipe tilted belly poles 3 and a horizontal steel pipe stay pole 4, the upper steel pipes 2 are welded with a pallet and a shear key block 5, and a concrete slab 6 forms an integrated structure together with the steel pipe truss through the pallet and the shear key block, and participates in load taking. A fulcrum joist 7 is arranged on the outer side of the upper steel pipe at each fulcrum, and the fulcrum joints are taken as the supporting points of the bridge span, and are supported at the pier tops of a Y-shaped bridge pier. As the invention adopts the steel pipe truss composite beams, the material properties of concrete and steels can be fully exerted, the steel pipe structure has good sealing performance and good plate stability, the improvement of the structure durability is facilitated, and the maintenance cost and the work load are reduced. The steel pipe truss has concise appearance, thereby obtaining better scenic effect; the supporting points of the bridge span are positioned at the two ribs of the main girder, the structural focus of the main girder is low, and the wind-resistance stability and the seismic stability of the structure are improved.

Description

A kind of novel steel tube longeron combination grinder bridge
Technical field
The present invention relates to a kind of bridge that adopts steel tube longeron combination grinder.
Background technology
Bondbeam can be given full play to material behavior, has the advantages that the rigidity of structure is big, economic and technical norms are good, at home and abroad is used widely.Bondbeam form commonly used at present mainly contains plate girder bondbeam, steel case beam bondbeam and steel truss bondbeam etc.
Railway, highway and municipal bridge engineering under the condition of manufacturing field, transportation and lifting conditions permit, adopt steel tube longeron combination grinder can give full play to the material behavior of concrete and steel.Steel tubular structure has good sealing property and plate stability, is beneficial to the raising structure durability, reduces maintenance costs and workload.The steel pipe truss profile is succinct, can obtain landscape effect preferably.
Summary of the invention
The objective of the invention is at above-mentioned present situation, aim to provide a kind of novel steel tube longeron combination grinder bridge, enrich the structure types of composite beam bridge, for a kind of new approaches are opened up in the design of composite beam bridge.
The implementation of the object of the invention is, a kind of novel steel tube longeron combination grinder bridge, steel pipe truss is for by single lower edge steel pipe 1, two " del " truss that wind up steel pipe 2, space steel pipe diagonal web member 3 and horizontal steel tube strut 4 are formed, welding pallet and shear connector 5 on the steel pipe 2 wind up, concrete slab 6 forms one by pallet and shear connector 5 with steel pipe truss, whenever stride the arranged outside fulcrum joist 7 of the steel pipe 2 that winds up at fulcrum place, fulcrum joist 7 is supported on the Dun Ding of " Y " shape bridge pier 8.
The present invention has following advantage:
1. adopt steel tube longeron combination grinder can give full play to the material behavior of concrete and steel;
2. steel tubular structure has good sealing property and plate stability, is beneficial to the raising structure durability, reduces maintenance costs and workload;
3. the steel pipe truss profile is succinct, can obtain landscape effect preferably;
4. the spanning fulcrum is positioned at girder two sides of body, and the main beam structure center of gravity is low, is beneficial to the wind resistance, the seismic stability that improve structure.
Description of drawings
Accompanying drawing is a structural representation of the present invention
The specific embodiment
With reference to accompanying drawing, steel pipe truss of the present invention is for by single lower edge steel pipe 1, two " del " truss that wind up steel pipe 2, space steel pipe diagonal web member 3 and horizontal steel tube strut 4 are formed, wind up welding pallet and shear connector 5 on the steel pipe 2, concrete slab 6 forms integrated structure and stressed jointly by pallet and shear connector 5 with steel pipe truss.
Whenever stride the arranged outside fulcrum joist 7 of the steel pipe 2 that winds up at fulcrum place, the supporting-point as spanning is supported on the Dun Ding of " Y " shape bridge pier 8.
