Abstract
The utility model discloses a steel tube arch bridge arch rib connecting mechanism which is used for connecting two adjacent arch rib steel tubes. The connecting mechanism comprises a plurality of stiffening ribs welded to the inner wall of the end portion of each arch rib steel tube and flange discs welded to the end portions of the stiffening ribs, wherein the stiffening ribs on one arch rib steel tube penetrate through a central hole of the corresponding flange disc to extend outwards to form guiding stiffening ribs, and the guiding stiffening ribs can penetrate through a central hole of the flange disc on the other arch rib steel tube to enable butt joint of the flange discs on the two arch rib steel tubes to be achieved fast and accurately during installation. When the steel tube arch bridge arch rib connecting mechanism is used for connecting steel tube arch bridges, the butt joint between the flange discs on the two arch rib steel tubes can be achieved fast, accurately and conveniently with little time and effort, and installation efficiency is high.
Description
Technical field
The utility model relates to steel structure bridge technical field, more particularly, relates in particular to a kind of steel pipe arch bridge arch rib bindiny mechanism.
Background technology
As shown in Figure 1, traditional steel pipe arch bridge arch rib bindiny mechanism comprises and is welded in a plurality of stiffening ribs 2 on arch rib steel pipe 1 inner wall of end and is welded in the flange 3 on stiffening rib 2 ends, when installation, flange 3 on two sections of adjacent arch rib steel pipes 1 is docked, and then fix by bolted-on, to realize the effective connection between adjacent two steel pipes.Because above-mentioned bindiny mechanism does not have guide function, be not easy when mounted location, especially the docking operation of flange wastes time and energy especially, and installation effectiveness is low.
utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and a kind of steel pipe arch bridge arch rib bindiny mechanism is provided, and improves the installation effectiveness of steel pipe arch bridge.
For achieving the above object, steel pipe arch bridge arch rib provided by the utility model bindiny mechanism, for connecting two sections of adjacent arch rib steel pipes, described bindiny mechanism comprises and is welded in a plurality of stiffening ribs on arch rib steel tube end part inwall and is welded in the flange on stiffening rib end, wherein the stiffening rib on one section of arch rib steel pipe stretches out and is provided with guiding stiffening rib through the centre bore of flange, described guiding stiffening rib can, through the centre bore of the flange on another section of arch rib steel pipe, make two sections of flange on arch rib steel pipe realize docking fast and accurately when mounted.
Adopt the utility model joint steel pipe arch bridge, can make two sections of flange on arch rib steel pipe realize docking fast and accurately, time saving and energy saving, quick and convenient, installation effectiveness is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art;
Fig. 2 is the structural representation of utility model.
In figure: 1-arch rib steel pipe; 2-stiffening rib; 3-flange; The 4-stiffening rib that leads.
The specific embodiment
Below in conjunction with the embodiment in accompanying drawing, the utility model is described in further detail, but do not form any restriction of the present utility model.
Consult shown in Fig. 2, a kind of steel pipe arch bridge arch rib provided by the utility model bindiny mechanism, for connecting two sections of adjacent arch rib steel pipes 1, described bindiny mechanism comprises and is welded in a plurality of stiffening ribs 2 on arch rib steel pipe 1 inner wall of end and is welded in the flange 3 on stiffening rib 2 ends, the centre bore that wherein stiffening rib on one section of arch rib steel pipe 12 passes flange 3 stretches out and is provided with guiding stiffening rib 4, described guiding stiffening rib 4 plays the effect of guiding when mounted, it can be through the centre bore of the flange 3 on another section of arch rib steel pipe 1, make two sections of flange 3 on arch rib steel pipe 1 realize docking fast and accurately, then adopt bolt to fix two flange 3 that connect are carried out to bolt, two sections of arch rib steel pipes 1 can be connected as one to structure.
