Technical Field
The utility model belongs to the technical field of the bridge erects, concretely relates to from anchor formula suspension bridge anchor span closure with support stop device that can slide.
Background
The process of forming the bridge of the self-anchored suspension bridge is a construction method of 'beam first and cable second'. And a full support structure cannot be erected in the beam forming process, so that the beam is formed by adopting a temporary cable-stayed bridge mode. For a multi-span continuous self-anchored suspension bridge, a method of position-shifting anchor span is mostly adopted for closure in the related technology.
The multi-span continuous bridge displacement anchor span closure method has great influence on the construction period of the bridge and the construction quality of the bridge. At present, the closure method of a multi-span continuous bridge usually comprises closure of side spans first and closure of middle spans last, and the construction is characterized in that the bridge span is usually small, and the longitudinal displacement (the driving direction of a bridge deck) of the concrete of the cast-in-place section beam body anchoring section or the anchoring section is very small or even negligible during closure. However, when the span of the bridge is large, the longitudinal displacement of the concrete of the anchoring section or the anchoring section is large, the longitudinal displacement of the slidable bracket for supporting the concrete of the anchoring section or the anchoring section is also large, and in order to avoid that the relative disturbance of the two ends of the closure opening affects the quality of the concrete of the closure opening, a device capable of limiting the longitudinal relative displacement of the beam bodies (the slidable bracket) on the two sides of the closure opening is needed.
SUMMERY OF THE UTILITY MODEL

Optionally, the support device further comprises a support claw, the support claw is L-shaped, one end of the support claw is connected to the side face of the support seat, and the other end of the support claw is flush with the lower end face of the gasket. The supporting claws can prevent the support from inclining or reduce the inclination tendency of the support, increase the friction force between the support and the cross beam, and replace the welding of the gasket and the cross beam by welding the supporting claws and the cross beam to protect the gasket.
Optionally, two adjacent supports are connected together by a cross bar. Further increasing the stability of the support.
Optionally, the gasket is formed by stacking a plurality of sheets on each other. The thickness of gasket is convenient to adjust according to the job site condition.
Optionally, the connection between the support claw and the support seat is welding. So that the connection between the supporting claw and the support is firm.
Optionally, the connection between the support jaw and the support is a hinge. The lower end face of the supporting claw and the lower end face of the gasket are kept flush.
