Abstract
The invention discloses an arch bridge supporting tool for improving arch bridge construction stability and a construction method thereof, belonging to the field of municipal construction. The arch bridge supporting tool disclosed by the invention comprises angle steel and at least two connecting rods horizontally fixed on an arch bridge main beam, wherein one side of the angle steel is perpendicular to the connecting rods and is fixedly connected with the connecting rod; and a horizontal forced plane used for supporting the arch is formed on the other side of the angle steel. The arch bridge supporting tool disclosed by the invention provides a stress plane for an arch bridge plate supporting system, and the condition that a stressed plane of scaffolding steel pipes (arches) is suspended is avoided; and moreover, in the arch bridge construction process, when the arch is constructed on the beam plate on the upper part of a web arch, the arch vertical rod is erected on the angle steel plane to form a lower stressed plane, and the upper load can be vertically transferred to the arch bridge main beam. The arch bridge supporting tool disclosed by the invention is simple in structure, convenient to operate, low in cost and high in construction efficiency, the stress stability of the arch can be greatly improved, and the construction safety is guaranteed.
Description
Technical field
The present invention relates to municipal construction field, prop up stake tool and construction method particularly to a kind of arch bridge increasing Arch Bridge Construction stability.
Background technology
In construction stages of arch bridge, due to arch bridge girder curvature and continually varying slope, cause the support (bow member) of spandrel arch top beam slab without plane of constraint, the biggest to the stability influence of arch bridge beam plate supporting system.
Prior art not yet discloses the technical scheme of any solution problem above, is unfavorable for Arch Bridge Construction stability.
Summary of the invention
In order to make up the deficiencies in the prior art, the invention provides a kind of arch bridge increasing Arch Bridge Construction stability and prop up stake tool and construction method.
The technical scheme is that
A kind of arch bridge increasing Arch Bridge Construction stability props up stake tool, is fixed on the connecting rod on arch bridge girder including angle steel and at least two levels；Described angle steel while being perpendicular to connecting rod and being fixedly connected with the connecting rod, the another side of described angle steel forms the horizontal force plane for scaffold vertical rod.
Preferably, described connecting rod is spiral.Spiral is used directly to be connected with arch bridge girder, and good fixing effect.
Preferably, a length of 10-30 centimetre of described connecting rod；The diameter of described connecting rod is at least 15mm.Connecting rod is used for supporting angle steel, and angle steel is as the stress surface of bow member, and therefore, connecting rod to have enough intensity.
Preferably, described angle steel is equal leg angle.
Preferably, the specification of described angle steel is ∠ 50 × 50 × 3.
Further, a length of 0.8-1.5 rice of described angle steel.
The arch bridge using described increase Arch Bridge Construction stability props up the method for stake tool construction, described connecting rod level is anchored on arch bridge girder, and described angle steel is fixed on connecting rod；After described angle steel is fixed on connecting rod, connect with described connecting rod is erected in connecting rod, and the another side of described angle steel forms the plane of constraint of level；During the Beam-Slab Construction bow member of spandrel arch top, bow member vertical rod is supported on this plane of constraint.
Preferably, described angle steel is welded in connecting rod.
The invention have the benefit that
The present invention is that arch bridge beam plate supporting system provides plane of constraint, it is to avoid the unsettled situation of scaffolding steel pipe (bow member) stress surface；In construction stages of arch bridge, during the Beam-Slab Construction bow member of spandrel arch top, bow member vertical rod is erected in angle steel plane, forms bottom plane of constraint, it is possible to by upper load vertical transmission in arch bridge girder.Present configuration is simple, easy to operate, low cost, and efficiency of construction is high, it is possible to be greatly improved the stability under loading of bow member, it is ensured that construction safety.
It addition, use the present invention to prop up the method simple possible of stake tool construction, be suitable to popularization and application.
