Description
Technical field
The present invention relates to a kind of stand alone type Sarasota built-in steel anchor beam accurate positioning device and installation method, belong to fixed building
Thing be exclusively used in the method and technology field built a bridge.
Background technology
The Sarasota of cable-stayed bridge is the main supporting member of whole bridge, and beam body load is converted into vertical load by suspension cable and passes
Passing Sarasota, Sarasota is complicated with the anchorage zone stress condition of suspension cable joint.In highway bridge, it is typically designed to built-in
Steel anchor beam structure, the horizontal component powerful to resist suspension cable.
Built-in steel anchor beam has two kinds of structures to design: 1) end to end structure, it is only necessary to location head joint steel anchor beam, follow-up steel anchor
Beam embedded board is directly seated on the steel anchor beam that a joint is complete；2) independent structure, then showing as each steel anchor beam is
Need the independent individual of location.
And steel anchor beam mounting means has two kinds: 1) separate type installation, both sides steel anchor beam embedded board is the most first installed, then steel is installed
Anchor beam beam body, the method cannot direct measurement and positioning, high-altitude connects low precision, and assembled difficulty is big；2) monoblock type is installed: by tower
Hanging device promotes whole sections steel anchor beam, and hand fit is in place, and the method precision is the highest, and tower crane cannot be right during adjusting attitude
Steel anchor beam installation site carries out real-time measurement, and adjustment difficulty is big, and location efficiency is low.
According to the applicant understood, the precision controlling of steel anchor beam location is the key technology of cable-pylon anchorage zone construction, directly affects
Whole anchorage zone steel anchor beam is linear and later stage hanging cable of stay cable is constructed, but above-mentioned steel anchor beam mounting process all exists: it is fixed to install
Position precision is the highest, it is impossible to realizes accurate adjustment, the time-consuming and shortcoming of poor effect, especially can not solve independent type steel anchor beam high-altitude
Overall location difficulty, the unmanageable problem of precision.
Summary of the invention
The technical problem to be solved in the present invention is, not enough for prior art, proposes entirety location, a kind of steel anchor beam high-altitude
Quick and precisely and the high free-standing Sarasota built-in steel anchor beam accurate positioning device of precision and installation method.
The present invention solves that one of technical scheme that above-mentioned technical problem proposes is: a kind of stand alone type Sarasota built-in steel anchor beam
Accurate positioning device, including support and be located on the concrete segment end face of bottom and be respectively positioned at the anchor slab of steel anchor beam end
Backing plate, limited block and transverse micro-adjustment mechanism；Multiple bedplates that described support includes being embedded on the concrete segment end face of bottom,
The column being fixed on bedplate, the two main spandrel girders being separately fixed on adjacent two root posts and being oppositely arranged and connection
The link of described column, described main spandrel girder is shaped with for laying the trapezoidal recessed uncovered of steel anchor beam beam body, described trapezoidal under
Recessed open-mouth is provided with and is fixed in steel anchor beam beam body and for filling up the wedge piece in space between steel anchor beam beam body and main spandrel girder
Block；Described backing plate is located at anchor slab bottom surface and can move up and down, and described limited block is resisted against at the anchor slab back side, described the most micro-
Regulating mechanism includes two bearing plates bearing against on anchor slab two sides and for moving a jack of each bearing plate.
The present invention solves that the two of the technical scheme that above-mentioned technical problem proposes is: a kind of stand alone type Sarasota built-in steel anchor beam
Accurately installation method, use claim 1 to 6 arbitrary as described in free-standing Sarasota built-in steel anchor beam accurate positioning device,
Comprise the following steps:
1) before the bottom concrete segment at Sarasota pours, difference mounting seat plate, spiral shell at the top of bottom concrete segment
Bar, tower wall embedded board and counter-force seat；
2) pouring bottom concrete segment, after bottom concrete segment solidifies, mounting bracket also makes the trapezoidal of winner's spandrel girder
The height of recessed open-mouth reaches preset height；
3) backing plate is installed, screws fine-tuning nut and make pad plate top surface height reach preset height, synchronize limited block and horizontal stroke are installed
To micro-adjusting mechanism；
4) using the hanging device that Sarasota is other, integral hoisting steel anchor beam, to installation site top, slowly transfers steel anchor beam so that steel
The anchor slab of anchor beam falls within a backing plate, and anchor beam beam body falls within the trapezoidal recessed open-mouth of main spandrel girder；
5) use correcting wedge to fill up space between steel anchor beam beam body and main spandrel girder, and carry out steel anchor beam Slope angle adjustment, full
After foot predetermined inclination degree, with bolt, correcting wedge is fixed in steel anchor beam beam body, forms entirety；
6) accurate measurement steel anchor beam anchor point transversal displacement, by transverse micro-adjustment mechanism, promotes anchor slab to move to adjust steel anchor beam
To predeterminated position.
The present invention uses technique scheme to provide the benefit that: 1) present invention is by being located at support, is provided with on support
The two main spandrel girders being fixed on adjacent two root posts and being oppositely arranged, main spandrel girder is shaped with for laying steel anchor beam beam body
Trapezoidal recessed uncovered, it is simultaneously provided with a backing plate, limited block and transverse micro-adjustment mechanism, so, steel anchor beam elevation and lengthwise position can
Determine in a pre-installation, lift the rear lateral attitude that only need to utilize transverse micro-adjustment mechanism accurate adjustment steel anchor beam in place, pass through correcting wedge
Control steel anchor beam positioning posture, it is possible to weaken steel anchor beam Affecting Factors of Accuracy in an orderly manner and save the adjustment time, efficiently solve
Common process positioning precision is the highest, it is impossible to realize accurate adjustment, the time-consuming and shortcoming of poor effect, solves Sarasota stand alone type
Steel anchor beam high-altitude entirety location difficulty, the unmanageable problem of precision；2) take into full account during support Design that major project structure is divided
Joint construction, is prevented effectively from and clashes with mould installing space in Sarasota, do not affect tower body concrete and normally pour, it is to avoid rope
Ta Neimo perforate, has saved cost；
3) this construction method thinking is distinct, simple to operate, Stability Analysis of Structures, work efficiency height, improves steel anchor beam installation accuracy.
