Abstract
High speed railway prefabricating box girder beam-ends spiral bar positioning device is related to prestress pipe spiral bar positioning device.Mainly to solve in construction at present by spiral bar binding on box beam reinforcing bar, design the problem of end discontinuity when leading to tensioning, beam-ends cracks.It includes positioning framework, and positioning framework is equipped with several groups crossbeam, and every group of crossbeam all includes the first crossbeam and second cross beam being fixed on positioning framework；It further include several positioning fixtures, each positioning fixture includes rear positioning ring, positioning ring is welded on first crossbeam and second cross beam afterwards, middle positioning ring is connect by first leg with rear positioning ring, there is prelocalization ring in front of middle positioning ring, prelocalization ring is connect by the second supporting leg with middle positioning ring, prelocalization ring, middle positioning ring, rear positioning ring the center of circle on the same line.Advantage is to overcome presstressed reinforcing steel position the problem of deviation occur.
Description
Technical field：
The utility model relates to prestress pipe spiral bar positioning devices, give high speed railway prefabricating box more particularly to one kind
The device of beam beam-ends spiral bar positioning.
Background technique：
The main function of high speed railway prefabricating box girder beam-ends spiral bar is to protect concrete under anchor not very heavy in tensioning
The pressure on top is destroyed, and ensures that prestress pipe position is accurate, to guarantee that the position of presstressed reinforcing steel is accurate, this needs to pass through anchor
Cavities, rubber extract pipe, spiral bar three realize with one heart.At present in construction, the method that spiral bar positioning uses mainly will
Spiral bar binds or is welded on box beam reinforcing bar, and the defect done so is it is difficult to ensure that anchor recess hole, rubber extract pipe, spiral bar three
Person is concentric, and when causing to block mould, anchor recess hole rear screw reinforcing rib will receive the extruding of end mould, location dislocation, or even can be suspended in rubber
On glue withdrawing pipe, end discontinuity when eventually leading to tensioning, beam-ends cracking.
Summary of the invention：
The technical problem to be solved by the utility model is to provide one kind can guarantee anchor recess hole, rubber extract pipe, spiral bar
The concentric high speed railway prefabricating box girder beam-ends spiral bar positioning device of three.
What above-mentioned purpose was realized in：It includes positioning framework, and positioning framework is equipped with several groups crossbeam, every group of crossbeam
It all include first crossbeam and second cross beam, the both ends of first crossbeam and second cross beam are all fixed on positioning framework；
It further include several positioning fixtures, each positioning fixture includes rear positioning ring, and rear positioning ring is welded on the first cross
On beam and second cross beam, middle positioning ring is set in front of rear positioning ring, middle positioning ring is connect by first leg with rear positioning ring, described
The diameter of middle positioning ring be less than the diameter of rear positioning ring, have prelocalization ring in front of middle positioning ring, prelocalization ring passes through second
Supporting leg is connect with middle positioning ring, and the diameter of the prelocalization ring is less than the diameter of middle positioning ring, prelocalization ring, middle positioning ring,
The center of circle of positioning ring is on the same line afterwards.I.e. the positioning fixture gradually becomes smaller from the front to the back, approximate tower-shaped.
The utility model has the advantages that：The setting position of positioning fixture is determined according to the position of box girder pre-stressed muscle, is positioned
The center of circle of fixture is overlapped with the center of circle in box girder pre-stressed muscle duct, and rubber extract pipe is stretched out from preceding positioning ring, and spiral bar covers
The middle positioning ring of positioning fixture is outer and is against on rear positioning ring, is fixed securely, outer edge and the anchor recess hole of rear positioning ring
EDGE CONTACT.After the installation is completed to box beam beam-ends spiral bar, the present apparatus is removed before the installation of box beam end mould, installs case beam-ends mould
Plate ensures that anchor recess hole, rubber extract pipe, spiral bar three are concentric in this way.Which overcome 900 tons of box beams of existing high-speed railway
Beam-ends spiral bar positioning device is insecure, and spiral bar displacement causes prestress pipe position inaccurate, to cause presstressed reinforcing steel
There is the problem of deviation in position.Present apparatus structure is simple, easy to operate, and save the cost is practical.
Detailed description of the invention：
Fig. 1 is the schematic view of the front view of the utility model；
Fig. 2 is the A-A view of Fig. 1.
Specific embodiment：
Referring to Figures 1 and 2, it includes positioning framework 1, and positioning framework is equipped with several groups crossbeam, and every group of crossbeam all includes
The both ends of first crossbeam 2 and second cross beam 3, first crossbeam and second cross beam are all fixed on positioning framework；
It further include several positioning fixtures, each positioning fixture includes rear positioning ring 4, and rear positioning ring is welded on the first cross
On beam and second cross beam, middle positioning ring 5 is set in front of rear positioning ring, middle positioning ring is connect by first leg 6 with rear positioning ring, institute
The diameter for the middle positioning ring stated is less than the diameter of rear positioning ring, there is prelocalization ring 7 in front of middle positioning ring, and prelocalization ring passes through the
Two supporting legs 8 are connect with middle positioning ring, and the diameter of the prelocalization ring is less than the diameter of middle positioning ring, prelocalization ring, middle positioning
Ring, rear positioning ring three are concentric.I.e. the positioning fixture gradually becomes smaller from the front to the back, approximate tower-shaped.
