Description
Technical field
The present invention relates to construction building technical field of structures, specially a kind of arch rib of long-span steel arch bridge assembly is interim
Bracket.
Background technique
With the development of China's cause of modernization, the construction of the large bridges such as domestic all kinds of bridge spanning the seas, river-spanning bridge is got over
Come more, these Longspan Bridges are steel structure bridge mostly, wherein steel arch bridge be used as across existing highway, railway, mountain valley,
The type of bridge in river has obtained a large amount of application.
With emerging in multitude for steel construction arch bridge, various construction methods are also applied therewith, for example cantilever is spelled
Dress method, branch frame in bulk method, stayed knotting method and the assembled method of jacking etc..But for easily just more than the steel construction of hundred meters of spans
Most of construction method is all limited to the factors such as the environment of construction site, place range size for arch bridge.Currently, most widely used
General or using setting up interim transverse girder between arch rib frame, the method for high altitude bulk carries out the installation of arch rib of long-span steel arch bridge, but
It is for many long-span steel arch bridges, span reaches rice up to a hundred, and arch rib weight reaches thousands of tons of, and arch rib rise reaches tens of
Rice, can encounter following point in high altitude bulk:
1, arch rib and stull weight are big, high to the structural bearing force request of temporary support；
2, arch rib rise is higher, its too high Out-of-plane Stability of support frame scaffolding height is difficult to ensure；
3, truss camber, lateral plane degree, absolute altitude, errors of centration are difficult to control.
Summary of the invention

The problem that assembly supporting frame construction difficulty is high, structural soundness is poor, arch rib splicing accuracy is not high.
(2) technical solution
To realize reliable above structure, simple installation, guarantee construction safety, facilitating the purpose of carrying out high accuracy install arch rib, this
Invention provides the following technical solutions: a kind of arch rib of long-span steel arch bridge assembly falsework, including upright bar and lacing, described
Lacing is welded at left and right sides of column, and the upright bar is formed with column, the upright bar by the combination of lattice with lacing
The column being composed with lacing is provided with X, Y direction between 16 groups and column altogether and is respectively arranged with a pair of suitable bridge Xiang Lian
It is that truss and direction across bridge contact truss, it is consistent in length to be arranged with multiple groups in the pillar construction that the upright bar is composed with lacing
Node section, between the upright bar node section be welded in bolt it is fixed by way of be fixed, it is oblique right that the lacing passes through
The setting of angular formula is connected and fixed at each node section of upright bar；The suitable bridge contacts truss to connection truss and direction across bridge and leads to
The rectangular frame structure of column-type is crossed, the suitable bridge contacts truss in such a way that bolt docks with direction across bridge to connection truss
It is fixed with upright bar；The column top that the upright bar and lacing are constituted is provided with transformation platform, and the transformation platform is held in the palm by top
Frame crossbeam and top support frame stringer constitute flat surface, and the top support frame crossbeam is along bridge to the upright bar top for being fixed on each column
Portion, the top support frame stringer direction across bridge are fixed on top support frame crossbeam, and top support frame stringer upper end is provided with very heavy
Top is equipped with jack bearing beam, is symmetrically arranged at left and right sides of the jack between the jack and top support frame stringer
A pair of of interim bearing beam of arch rib, direction across bridge is equipped with channel steel, the channel steel and top support frame crossbeam between the top support frame crossbeam
It is fixedly connected in such a way that bolt docks, the channel steel upper surface is equipped with steel mesh piece.
Further advantage, the top support frame crossbeam, top support frame stringer, jack bearing beam and the interim bearing beam of arch rib are equal
For Two bors d's oeuveres or Three kinds of hors d'oeuvres I-steel.
Further advantage, between the column that the upright bar and lacing are constituted by along bridge to contacting truss and direction across bridge contacts
Truss connection, and it is all made of space truss form to the connection that connection truss and direction across bridge contact truss and column along bridge, and
Upright bar, column bottom end are fixedly connected with job location body frame when installation.
Further advantage, the jack structure type are screw jack, and jack upper end and arch rib when installing
Lower surface fits closely.
Further advantage, it is horizontal that the channel steel is uniformly layed in two sides top support frame in such a way that direction across bridge, spacing is 650mm
Lower flange of girder edge position, and channel steel upper surface is fixedly connected with steel mesh piece.
(3) beneficial effect
Compared with prior art, the present invention provides a kind of arch rib of long-span steel arch bridge assembly falsework, have following
The utility model has the advantages that
1, this kind of arch rib of long-span steel arch bridge assembly falsework, is taken with upright bar lacing in work progress fill in the early stage
Column and construction site in bracket install and fix, and all parts such as transformation platform upper end jack are passed through into top support frame
Horizontal, stringer docks fixation with rod end, to complete building for support frame, when carrying out arch rib assembling construction, by every side arch rib
9 segments production are divided to march into the arena, it is by truck crane that the rib-hoisting of each segment is interim to the corresponding arch rib of installed position afterwards
On bearing beam, by being fixed temporarily between the arch rib of each segment and between two sides arch rib and stull by connecting plate to guarantee that it is steady
Fixed, then site operation personnel are finely adjusted by the arch rib absolute altitude of each segment of jack pair, are corrected, then weld arching, complete
It constructs at arch rib in assembly, compared to traditional arch rib assembly support frame, this kind of temporary support construction is completed simultaneously
In arch rib arching and after stablizing, is unloaded step by step by jack, separate support frame with arch rib, finally remove support again
Frame must be followed first to fill and be torn open afterwards in support frame demolishing process, filled the principle first torn open afterwards and gradually removed, be connected to conversion with jack pair
Platform upper end arch rib can facilitate construction personnel accurately to adjust the absolute altitude of each segment arch rib, improve the installation accuracy of arch rib；
2, this kind of arch rib assembly temporary support simultaneously, by the lattice column being made of upright bar and lacing, and its it is vertical
The fixed form of each segment of column decreases while ensure that firm support frame structure, construction safety and construction quality
The investment of large-scale hoisting machinery equipment, reduces construction cost, and the assembly of each segment arch rib, fine tuning, correction, welding and rectifys
The processes such as just operate on the transformation platform on falsework platform, it is ensured that safety saves artificial, falsework conduct
One Auxiliary support not only contributes to the splicing accuracy of control arch rib in this project, also ensures arch rib during the installation process
Overall stability, provide reference for similar engineering；
3 and in the construction process, construction personnel passes through the screw type each segment of jack pair arch rib on transformation platform
When being finely adjusted, guarantees that platform is firm in such a way that channel steel is fixed on top support frame crossbeam, while operating personnel is safe, pass through
The steel mesh piece that there is uniform place mat on channel steel avoids in work progress, and construction material etc. falls between rig bracket crossbeam and applies
Workshop, it has avoided falling object from high altitude and has threatened to construction site staff, further ensured the construction peace of support frame
Entirely.
