Abstract
The utility model relates to a front beam and rear arch stacking device for a steel arch bridge. The front beam and rear arch stacking device comprises a steel box beam support, a segmented steel box beam, a steel arch rib support and a segmented steel arch rib. The steel box beam support comprises multiple rows of steel tube lattice column piers, a force-bearing cross beam which stretches across and is placed on the tops of all rows of the steel tube lattice column piers and a supporting stand column which is vertically arranged on the force-bearing cross beam. The supporting stand column supports the segmented steel box beam in a matched mode. The steel arch rib support comprises a steel arch rib support body arranged on the steel box beam which is well laid, an arch rib force-bearing plate arranged at the top end of the support body and a supporting locating grille arranged on an arch rib force-bearing platform. The supporting locating grille is composed of multiple supporting plates which are vertically arranged on the arch rib force-bearing platform, wherein the tops of the supporting plates are on the same bevel. The front beam and rear arch stacking device for the steel arch bridge is firm in supporting and convenient to assemble and disassemble, a stress supporting structure can be arranged reasonably, and the construction sequence in the whole construction process is optimized more reasonably.
Description
Technical field
The utility model relates to a kind of constructing device of setting up of steel arch beam, is specifically related to the first beam rear arch of a kind of steel arch bridge polyunit.
Background technology
Along with the development of China's speedway, large span prestressed concrete bent cap can be widely used in highway bridge, and it is attractive in appearance that it not only increases bridge, can greatly improve the ground space under bridge simultaneously, outstanding in the city area advantage of ground space restriction.For the engineering characteristic of large span prestressed concrete bent cap, generally adopt the construction of conventional bracket (φ 48*3.5mm steel pipe full framing) method, or adopt the construction of bracket (anchor ear) method form erecting technology.
Construct at Du Dun (large span) pre-stressed concrete coping, if adopt the construction of bracket (anchor ear) method form erecting technology, exist section steel manufacture investment large, engineering quantity is large, instrument versatility poor (only a project is used), the series of problems such as technical difficulty is high, and installing space is narrow, palpus main equipment coordinative construction.Adopt the construction of conventional bracket (φ 48*3.5mm steel pipe support) method, support is pacified, is torn technology maturation open, and fast and safely, but basic specially treated workload is larger, long construction period, much time wealth.
Utility model content
The purpose of this utility model is the problem and shortage for above-mentioned existence, provide a kind of can set up easy for installation, cost cost is low, the first beam rear arch of the steel work of short construction period polyunit.
For achieving the above object, the technical scheme of taking is:
The first beam rear arch of a kind of steel arch bridge polyunit, comprise steel box beam bracket, be placed on segmentation steel case beam, steel arch rib support and segmentation steel arch rib on steel box beam bracket, described steel box beam bracket comprise many rows steel pipe frame column pier of being vertically arranged on hardened ground, across and be placed on the load crossbeam at each row's steel pipe frame column pier top and be vertically arranged on the support post on load crossbeam, described support post mates support with segmentation steel case beam; Described steel arch rib support comprises the steel arch rib rack body that is arranged on the steel case beam laying, is arranged on the arch rib load platform on rack body top and is arranged on the supporting and location grid on arch rib load platform, and described supporting and location grid are to be vertically arranged on multiple tracks top on the arch rib load platform gripper shoe on same inclined-plane.
Described support post side is welded with bearing diagonal, described adjacent two support post interval 800mm ~ 1500mm.
On described steel box beam bracket and steel arch rib support, be provided with mounting attachment.
Adopt technique scheme, obtained beneficial effect is:
The utility model support firm, assembly and disassembly convenient, can the stressed braced structures of rational design, more reasonably optimizing the sequence of construction in whole work progress, be convenient to overall assembling and build, simultaneously shuttering supporting for convenience detach, can be applicable to setting up of different steel arch bridges, highly versatile.
