Description
Technical field
The present invention relates to a kind of in bridge rotating method construction ball pivot installation process, the construction technology that adopts special-purpose location skeleton to position, adjust.
Background technology
After Bridge Rotation Construction Technique refers to that bridge construction is made to (cast or splicing) is shaped in non-design axial location, by a kind of job practices in place of turning.It can be converted into the operation in the obstacle overhead on the bank or subaerial operation.According to the rotation direction of bridge construction, the method that it can be divided into vertical turn construction method, Horizontal Swing Construction method and flat turn and combine with vertical transfer, wherein to flat turn the method application at most.
The method of flatting turn is disturbed little, safe to existing railway, speedway; For high mountain gorge, The water is deep and the current fast or the river course of often navigation on the advantage of the large span structure that sets up be also very significant.
The method of flatting turn realizes bridge rotating by rotor system, and rotor system is comprised of ball pivot, slideway, spike etc., and ball pivot, slideway be as the core of rotor system, and its location is adjusted particularly important.Ball pivot commonly used is divided into steel concrete ball pivot and steel ball hinge, steel ball hinge have machining accuracy high, can bear the advantages such as little than the large weight of turning, friction factor, that the time of turning is short, safe and reliable, therefore in the method for turning at present construction, usually use the steel ball hinge, under this background, need to a kind ofly with skeleton, carry out the location of steel ball hinge, slideway and the construction technology of adjustment.
Summary of the invention
The object of the invention is to solve steel ball hinge, slideway in the elevation of accurate location, ball pivot sphere and the slideway of installation process median-plane location and the adjustment of the discrepancy in elevation, and provide a kind of, with the location skeleton, beam Rotary ball hinge and slideway are positioned to the construction technology of adjustment.
To achieve these goals, the technical scheme that the present invention takes is: a kind of with the location skeleton beam Rotary ball hinge and slideway are positioned to the construction technology of adjustment, comprise the following steps:
1, ball pivot, slideway frame design are made
Ball pivot, slideway skeleton adopt the angle steel welding to form, and weld seam all adopts continuous fillet weld, and postwelding guarantees the distortionless distortion of group welding piece, at ball pivot, slideway skeleton end face, adjusting nut is set simultaneously;
2, ball pivot, slideway skeleton built-in fitting arrange
When bearing platform construction, carry out the setting of ball pivot, slideway skeleton base built-in fitting, the deviations of built-in fitting is not more than 5mm, and emits the centre of location, the slideway plan-position of ball pivot on cushion cap;
3, ball pivot, slideway framework location are adjusted
Employing pad steel-sheet method under ball pivot, slideway skeleton base is carried out the adjustment of framework location absolute altitude, after adjustment, takes first interior rear outer welding sequence to carry out ball pivot, the welding of slideway skeleton base;
4, utilize skeleton to carry out ball pivot and slide rail scale height adjustment
Ball pivot skeleton base has welded, ball pivot utilizes ball pivot skeleton adjusting nut to carry out the adjustment of ball pivot absolute altitude after lifting; Slideway skeleton and slideway steel plate are adjusted with the bolt segmentation after dividing eight joints to install, and after a joint slideway skeleton adjustment completes, carry out the adjustment of next section slideway, and adjust on survey limit, limit.
Beneficial effect of the present invention is: (1) skeleton structure is simple, reasonable in design, Stability Analysis of Structures, installation rate are fast.(2) adjusting nut by the skeleton end face carries out ball pivot, the adjustment of the slideway discrepancy in elevation, and easily and effectively, it is high that the discrepancy in elevation is adjusted precision in this measure.

The specific embodiment
Below in conjunction with specific embodiment, further set forth this patent.Should be understood that these embodiment only are not used in the scope of restriction this patent for this patent is described.Should be understood that in addition those skilled in the art can make various changes or modifications this patent after the content of having read this patent instruction, these equivalent form of values fall within the application's appended claims limited range equally.
The difficult point of framework location adjustment construction of the present invention, measure is:
1, skeleton, all by factory's welding production, guarantees the welding quality of skeleton.
2, skeleton takes to reinforce location measure in transportation, distortionless distortion while guaranteeing that skeleton is transported to job site.
3, skeleton base steel plate built-in fitting is set on cushion cap, installation deviation is not more than 5mm.
4, after framework location according to survey data, adopt rational welding sequence to carry out the welding of skeleton base.
5, when building the skeleton concrete, take fixation, avoid skeleton that off normal occurs in concreting process.
Install in conjunction with No. 11 line north extension line project Shanghai-Nanjing Expressway bridge Rotary ball hinges of Shanghai Rail Transit and slideway, the specific embodiment of the invention method be described:
1, ball pivot, slideway frame design are made
As shown in Figures 1 to 6, after ball pivot, slideway frame design complete, in the processing of professional ball work production unit, ball pivot, slideway skeleton are formed by the angle steel welding, and weld seam all adopts continuous fillet weld, and the while arranges adjusting nut at ball pivot, slideway skeleton end face.In transportation, in ball pivot, slideway skeleton, add section steel reinforcement, guarantee that skeleton is transported to distortionless distortion behind job site.
2, ball pivot, slideway skeleton built-in fitting arrange
When bearing platform construction, the pre-embedded steel slab of 4 100mm * 100 * 20mm is set in ball pivot, slideway skeleton base corresponding position, absolute altitude, lower than design elevation 5mm, allows some leeway to ball pivot, the adjustment of slideway skeleton absolute altitude.Emit the centre of location, the slideway plan-position of design ball pivot on cushion cap.
3, ball pivot, slideway framework location are adjusted
The steel-sheet method of employing pad 1mm, 2mm under ball pivot, slideway skeleton base is carried out the adjustment of framework location absolute altitude, controls four jiaos of discrepancy in elevation and is not more than 2mm.After adjustment, take the mode be symmetrically welded to weld, welding sequence be first in after outside, along same direction, welded.
4, utilize ball pivot, slideway skeleton to carry out ball pivot and slide rail scale height adjustment
Ball pivot skeleton base utilizes ball pivot skeleton adjusting nut to carry out the adjustment of ball pivot absolute altitude after having welded (Fig. 1,2), ball pivot lifting.The method of adjusting is by the elongated tooth (the highest elevation adjustable range is 6cm) of opening of adjusting bolt, along a direction, adjusts successively adjacent 2 discrepancy in elevation.
Slideway skeleton and slideway steel plate (Fig. 3,4,5) minute eight joints are installed (Fig. 6).Bolt is regulated concrete grammar and principle is: first tight after pine, 4 nuts of adjacent Internal and external cycle form one group, first in after outside, the amplitude that 4 nuts are adjusted is unsuitable excessive, is controlled at 2 to 3mm, avoids steel plate to produce distortion.After one joint slideway adjustment completes, clockwise (or inverse clock) carries out the adjustment of next section slideway, and adjust on survey limit, limit.
