Description
Technical field
The utility model relates to bridge construction support technology field, particularly relates to a kind of bridge main subarch rib docking auxiliary stand structure.
Background technology
Some large bridges are constructed, arch rib on bridge is divided into some sections, after being positioned at the main arch rib location at bridge two ends, then with crossing suspender, subarch rib is docked on main arch rib successively, then welding effect is carried out, during main arch rib location, one end is connected with bridge pier, the other end needs auxiliary stand to support, during docking, the weight of major-minor arch rib needs auxiliary stand to bear, in the process of simultaneously docking, subarch rib can produce a very large horizontal applied force to auxiliary stand in the process of main arch rib end movement, the stability of auxiliary stand can be had a strong impact on like this, easily cause security incident.
Utility model content
The utility model, in order to solve the aforementioned problems in the prior, provides a kind of supporting & stablizing, use safety, can ensure the auxiliary stand structure that major-minor arch rib accurately docks.
To achieve these goals, the utility model adopts following technical scheme:
A kind of bridge main subarch rib docking auxiliary stand structure, comprise steel structure support, the upper end of described steel structure support is provided with the gripper shoe of inclination, main arch rib upper end is overlapped on the low inclined-plane, one end of gripper shoe, one end upper side low in gripper shoe is also provided with the steel liner plate for supporting main arch rib, one end high in described gripper shoe is also provided with jack, the upper end of jack is provided with wedge shape protector, described gripper shoe is also provided with sliding plate support, the upper end of sliding plate support is provided with the substrate parallel with gripper shoe, is provided with slide plate on the upside of described substrate.Main arch rib outer end overlap joint is on the supporting plate also by steel liner plate height-fine adjustment, then by suspender, subarch rib is hung the outer end of close main arch rib, subarch rib passes through Cable tension between two ends, transfer suspender gradually, the end of subarch rib is made to ride on jack, then control jack to decline, the two ends of subarch rib are made to be pressed on slide plate, then cable wire is unclamped gradually, the two ends of subarch rib are outwards opened along slide plate and are docked with main arch rib, now the active force of subarch rib is completely vertically pressed on steel structure support, to main arch rib, the joint of subarch rib carries out weld job, finally dismantle steel structure support, in major-minor arch rib docking work progress, steel structure support can not be subject to powerful horizontal applied force, supporting & stablizing, use safety.
As preferably, be welded to connect between the lower end of described sliding plate support and gripper shoe, the both sides, upper end of substrate are provided with slide rail, and slide rail is provided with chute, and the downside of described slide plate is provided with the guiding raised line coordinated with chute.
As preferably, the bottom of described chute is provided with needle roller, and the lower end of described guiding raised line contacts with needle roller, and the both sides, openend of described chute are provided with spacing blend stop, and the lower end of described guiding raised line extends to form separation prevention bar to both sides.Needle roller can reduce the frictional force led between raised line and chute, and spacing blend stop, separation prevention bar can be deviate from by anti-limited slip plate from chute, use safer.
As preferably, the upper side of described slide plate is fixed with polyfluortetraethylene plate.Because subarch rib entirety is curved, the contact surface of itself and slide plate is also cambered surface, therefore on the upside of slide plate, fixes polyfluortetraethylene plate, deformation can occur thus adapt with subarch rib cambered surface during polyfluortetraethylene plate pressurized.
Therefore, the utility model has supporting & stablizing, use safety, can ensure the beneficial effect that major-minor arch rib accurately docks.
