Description
Technical field
It is consolidated the present invention relates to technical field of bridge construction more particularly to a kind of composite beam steel reinforced concrete joining section and fine tuning fills
It sets.
Background technique
Steel structure bridge is a kind of bridge for using steel as major bearing structures, with the continuous improvement of technical level,
Mountable steel bridge is all widely applied all over the world.
Currently, concreting is symmetrical in being extremely difficult on joining section girder steel in steel reinforced concrete joining section work progress, exist
It topples possibility.Concreting when on joining section girder steel generally using unilateral counterweight or it is interim it is affixed by the way of steel reinforced concrete is connected
Section plays firm effect.In other side increase equivalent counterweight to keep balancing while unilateral counterweight method is casting concrete,
Have the advantages that it is easy to operate, do not injure girder steel base material, but counterweight loading velocity and quantity are not easy to control, and safety coefficient
It is low.Temporarily affixed method is by welding that girder steel is temporarily affixed with bracket, forms girder steel and lower bracket and stablizes entirety, has
Advantage easy for construction, at low cost, still, this method is high to lower bracket stability requirement and welding operation injures girder steel mother
Material, limiting factor are more.Steel reinforced concrete joining section mostly as the controlling component being connect with steel structure bridge closure section, longitudinal absolute altitude and
Cross fall directly influences the difficulty or ease and integral linear of closure section installation, the absolute altitude and slope using closure section itself general at present
Degree adjustment is used as closure section installation method, but the method is unresolved for steel reinforced concrete joining section absolute altitude and gradient offset issue, construction
Difficulty is big, installs linear poor.
Summary of the invention

The crossbeam and cantilever beam that need to consolidate or finely tune component are close to or are pushed down to the jack of lower limit beam, lower limit beam；
The lower support bracket is fixed on support jig, and middle part connection screw thread steel from top to bottom sequentially passes through upper limit
Beam, lower limit beam and lower support bracket, upper limit beam, the reserved required screw thread of lower limit beam and lower support bracket middle part
Hole, and fixed by nut and lower support bracket, by the nut on upper limit beam as adjustable limit, limit top thousand
The relative position of Jin Ding mechanism and middle part connection screw thread steel.
Preferably, the lower limit beam is Two bors d's oeuveres i-beam frame.
Preferably, the jack is stood on lower limit beam, is pushed down at the top of jack by upper limit beam.
Preferably, the lower support bracket includes the steel pipe pile bracket being fixed on support jig, is placed on middle part connection
Gasket and steel nut on screw-thread steel.
Preferably, the steel pipe pile bracket is fixed by welding with support jig.
Preferably, the junction of the middle part connection screw thread steel and upper limit beam and lower limit beam is provided with gasket.
