Technical field
The utility model relates to the anchorage style in a kind of movable bridge, relates in particular to a kind of vertical transfer movable bridge bearing support anchor structure that is used for.
Background technology
Movable bridge is meant and is navigation needs, the bridge of mode foldings such as superstructure can be revolved perpendicularly to revolve, to put down, lifting.Busy when land transport, ship's navigation is arranged on the river and fixed bridge can not be built in navigational clearance when above, just need to build movable bridge, thereby to solve land and water transportation.Movable bridge commonly used has: the 1. upright bridge that changes.The bridge of the rotatable folding on facade of the bridge span structure above the navigation channel.The whole title list Ye Shili that strides bascule changes movable bridge from an end folding; Folding is divided into the upright movable bridge that changes of title double-valve type of two parts bascule from two ends.Bascule is provided with mechanical device and electrical equipments such as hinge and balance weight.2. lift bridge.The spanning of navigation part is made liftable structure movable bridge two ends respectively has a pylon, places with mechanical, electrical device and balance weight.3. swing bridge.Bridge span structure is around the movable bridge of a vertical pivot rotation.No matter be the movable bridge which kind of opens form; All can relate to the anchoring of different modes; Require to be satisfied its peripheral shearing and resistance by the bearing capacity of anchoring body after the anchoring; Especially to the anchoring of bearing support, the absolute error of requirement itself and a plurality of relative errors need satisfy outside the mechanical system requirement, can bear level and vertical load simultaneously.At present, direct pre-buried steel member is adopted in the anchoring in to movable bridge between the bearing support of block bearing and the main pier usually, because concrete need vibrate; Add the concrete shrinkage reason; The position of steel member is difficult to guarantee, therefore, can not reaches the job requirement of mechanical system.
The utility model content
To above-mentioned prior art, the utility model provides a kind of anchor structure of vertical transfer movable bridge bearing support, and this anchor structure can make the absolute error of itself and a plurality of relative errors need satisfy outside the mechanical system requirement, can bear level and vertical load simultaneously.
In order to solve the problems of the technologies described above, the technical scheme that the anchor structure of the utility model vertical transfer movable bridge bearing support is achieved is: this anchor structure comprises main pier and bearing support fixation steel plate, anchoring between said main pier and the said bearing support fixation steel plate; Said anchoring comprises anchor plate, little swollen concrete connecting portion of exempting to shake, a plurality of adjusting screw(rod), a plurality of T hook bolt that is set with steel pipe; Said anchor plate is arranged in the said main pier and is parallel with said bearing support fixation steel plate; In said main pier, be positioned on the periphery of anchoring and be provided with a plurality of adjusting screw(rod) pre-embedded steel slabs; Said adjusting screw(rod) is connected in said bearing support fixation steel plate and said adjusting screw(rod) pre-embedded steel slab; The head of said T hook bolt is positioned at said anchor plate end, and the other end of said T hook bolt stretches out anchoring after passing said bearing support fixation steel plate.
The anchor structure of the utility model vertical transfer movable bridge bearing support wherein, has the gap between said T hook bolt and the suit steel pipe above that.Be provided with a cutout with said bearing support fixation steel plate contact jaw on said little swollen concrete connecting portion of exempting to shake.Said a plurality of T hook bolt that is set with steel pipe is covered with on described bearing support fixation steel plate according to array.
Compared with prior art the utlity model has following beneficial effect: bearing support fixation steel plate horizontal tilt angle is not more than 1 '; Two bearing support fixation steel plates of same main pier discrepancy in elevation is not more than 2mm, and four bearing support fixation steel plate discrepancy in elevation of two main piers are not more than 3mm.If construction error has expansion slightly, will cause equipment attrition, reduce service life of equipment.In the technology of anchoring, comprise the little swollen concrete part of shaking of exempting from that first phase concreting part and second phase build.Wherein, in the first phase concreting, vibrate because of needs adopt machinery, if directly imbed steel member group wherein, construction error only can reach ± 20mm, is 10 times that mechanical system requires.And be to come regulating shaft bearing fixation steel plate through adjusting screw(rod) in the utility model, can satisfy the mechanical system requirement; In exempting from of building of second phase shaken little swollen concrete, because of little swollen concrete of exempting to shake need not vibrate, and anti-contracility can be superior, the plan-position precision that makes the bearing support fixation steel plate within ± 2mm, thereby effectively control construction error.In addition, the cutout in the utility model can satisfy horizontal force request, and the T hook bolt that is enclosed within the steel pipe can satisfy the vertical applied force requirement.
