Abstract
Disclosed is an arch bridge suspender component, comprising a finished cable 5, an upper anchor head 6 which connects 5, and a lower anchor head 4. The utility model is characterized in that the suspender component also comprises a pulling rod component 1, a ball-shaped hinge 2 and a connecting sleeve 3; the lower end of the pulling rod component 1 is fixed at the lower surface of the beam; the upper end of the pulling rod component 1 is connected to an upper nut 21 of the ball-shaped hinge 2; an lower nut 22 of the ball-shaped hinge 2 is connected to the lower end of the connecting sleeve 3 by threads; the lower anchor head 4 is connected to the top end of the connecting sleeve 3; the pulling rod component consists of a pulling rod 12 and a nut 13; the upper anchor head 6 and lower anchor head 4 are separately cold-molded anchor or button head anchor, or both are cold-molded anchor or button head anchor. The suspender component has simple antisepsis and largely increased reliability; as the ball-shaped hinge is arranged in the suspender component, the utility model can effectively prevent the affiliated stress of the carling stretching of the bridge caused by temperature stress; the utility model can also prevent the affiliated stress and bending moment of the short suspender caused by temperature stress and construction error.
Description
One, technical field:
The utility model relates to a kind of suspension rod assembly, particularly a kind of arch bridge suspender assembly.
Two, background technology:
At present various arch bridges, in concrete-filled steel tubes arch bridge, concrete arch-type bridge, steel case arch bridge, suspension rod all is to adopt chill casting anchor or bulb-end anchorage, forms the suspension rod system by anchor head 4 under anchor head or the bulb-end anchorage under anchor head 6, finished product rope 5 and the chill casting anchor on anchor head or the bulb-end anchorage on the chill casting anchor.The suspension rod upper end is passed arch ring and is anchored at plane on the arch ring 8 by last anchor head, the suspension rod lower end is passed crossbeam and is anchored at crossbeam 7 lower planes (referring to Fig. 2) by following anchor head, the load that crossbeam bears is passed to cable body by following anchor head, and cable body is passed to anchor head, and last anchor head is passed to arch ring again.There is following shortcoming in this kind suspension rod system: bridge floor is because the impact of vehicle or other load, and the change in length of the bridge floor longeron that causes owing to variations in temperature is destroyed plane and following anchor head junction on the crossbeam, cause poor sealing, be easy to infiltration and cause anchor head and cable body steel wire immersion corrosion steel wire down, have a strong impact on the use of suspension rod, gently then shorten suspension rod application life, heavy then cause that bridge caves in.
Three, summary of the invention:
Technical problem to be solved in the utility model is: solve arch bridge suspender lower end corrosion-resistant problem, eliminate because thermal stresses causes the bridge floor drift, thereby suspension rod is produced additional stress and because the additional bending moment that construction error produces suspension rod.
Its technical scheme of dealing with problems is: bottom, suspension rod crossbeam position increase by one by rod assembly, spherical hinge on the rigid structures that constitutes of lower nut, adapter sleeve, the rod assembly lower end is anchored in the crossbeam lower plane, the upper end is connected with adapter sleeve by spherical hinge, and anchor head links into an integrated entity under adapter sleeve and the suspension rod.
Its concrete structure is: a kind of arch bridge suspender assembly, comprise finished product rope and the last anchor head that is attached thereto, following anchor head, it is characterized in that: this suspension rod assembly also comprises the rigid structures that is made of rod assembly, spherical hinge, adapter sleeve, rod assembly upper end is connected with top nut in spherical the hinge, lower nut and adapter sleeve lower end be by being threaded in the spherical hinge, links to each other on following anchor head and the adapter sleeve.
Upper and lower anchor head can be respectively chill casting anchor or bulb-end anchorage, can all be chill casting anchor or bulb-end anchorage simultaneously also.
During use, upper end with suspension rod---be that finished product rustling sound body one end is anchored in plane on the arch ring by last anchor head, and the lower end of suspension rod---the other end that is finished product rustling sound body links to each other with adapter sleeve by following anchor head, the rod assembly upper end is connected with adapter sleeve by spherical hinge, and the rod assembly lower end is anchored in the crossbeam lower plane, thereby whole suspension rod assembly is linked into an integrated entity, and be anchored between the crossbeam of the arch ring of arch bridge and bridge.
Owing to adopt said structure, the utlity model has following advantage:
1, improve the antiseptic property of suspension rod effectively, and reliability improves greatly.Rod assembly is installed in the crossbeam, pours into behind the anticorrosion grease and only need make regular check on, and can guarantee safety.Anchor head under the ground tackle is risen to the crossbeam top, solved time anchor head waterproof problem.
2, spherical hinge is set in the suspension rod assembly, has reduced the bridge longeron elongation that causes owing to thermal stresses effectively and the subsidiary stress of suspension rod increase; Can also eliminate on the arch ring that causes owing to construction error pre-pipe laying effectively and misalign the additional bending moment that causes the suspension rod increase with the pre-pipe laying of crossbeam;
3, in arch bridge, short steeve uses this suspension rod assembly can prevent the generation of this situation effectively owing to subsidiary stress and moment of flexure that thermal stresses and construction error cause are even more serious.
Four, description of drawings:

Fig. 2: existing arch bridge suspender modular construction and installment state schematic diagram.
Five: the specific embodiment:
Embodiment:
A kind of arch bridge suspender assembly comprises finished product rope 5 and the last anchor head 6 that is attached thereto, following anchor head 4, and this suspension rod assembly also comprises the rigid structures that is made of rod assembly 1, spherical hinge 2, adapter sleeve 3, rod assembly 1 upper end and spherical top nut 2 of cutting with scissors in 2
1Connect lower nut 2 in the spherical hinge 2
2With adapter sleeve 3 lower ends by being threaded, anchor head 4 links to each other with adapter sleeve 3 upper ends under the bulb-end anchorage.
Described rod assembly 1 is by pull bar 1
2, nut 1
3Form, above-mentioned upper and lower anchor head can be respectively chill casting anchor or bulb-end anchorage, can all be chill casting anchor or bulb-end anchorage simultaneously also.Among Fig. 1,1
1Be pad.
During use, upper end with suspension rod---be that finished product rope 5 cable bodies upper end is anchored in plane on the arch ring by last anchor head 1, anchor head 4 links to each other by thread connecting mode with adapter sleeve 3 and the other end of finished product rope 5 cable bodies passes through down, rod assembly 1 upper end is connected with adapter sleeve 3 by spherical hinge 2, rod assembly 1 lower end is anchored in the crossbeam lower plane, thereby whole suspension rod assembly is linked into an integrated entity, and be anchored between the crossbeam of the arch ring of arch bridge and bridge.
