Description
Technical field
The utility model belongs to technical field of bridge construction, particularly relates to high pier over-form construction.
Background technology
High pier adopts over-form construction usually, three groups of vertical sections templates are formed turns over mould template system, turn over the mould last time at every turn and to build below pier shaft two sections templates in top layer template, form the template that next pier shaft turns over mould sections, and before carrying out next pier shaft and turning over mould sections model sheetinstallat, first must carry out the installation colligation of next pier shaft sections reinforcing bar, owing to there is no outrigger in over-form construction, personnel do not have the job platform of reinforcement installation colligation, and reinforcement installation moves stock and provides a job platform and security protection for operating personnel carries out reinforcement installation colligation in high-altitude exactly.
Current in high pier over-form construction, common reinforcement installation colligation job platform has three kinds: 1, utilize and turn over mould and pier shaft and reserve pin-and-hole or directly utilize and turn over mould and install rod iron latch to pulling eye, bottom steel welding is connected into a framework, on framework, double scaffold tubes is set up in welding, plug-in safety net, scaffold tubes frame arranges upper and lower two job platforms, the general 12m of frame pipe height, four jacks and wire rope is utilized upwards to promote time mobile, after putting in place, latch is installed, structural steel frame falls within latch, removes jack Hoisting System; 2, Thin-wall Hollow Pier utilization is first turned over mould and is connect high internal mold, and the mobile stock be connected into by steel welding hangs on internal mold top, and operating personnel carries out reinforcement installation colligation by upper lower platform; 3, utilize the back cord turning over mould, the column of the mobile stock be connected into by steel welding directly drops on top layer and turns on mould back cord, and personnel carry out reinforcement installation colligation by upper and lower job platform.
There is shortcoming, method 1 in above-mentioned three kinds of methods: mobile stock height is higher, poor stability, and mobile by jack lifting, translational speed is slow, length consuming time, and during installation latch, danger is larger; Method 2: mobile stock is placed in internal mold top by top cross-bar, and job platform is suspended structure, and wind resistance is poor, poor stability, easily causes the imbalance to side load, poor stability.Method 3: mobile stock column is directly placed in and turns on mould back cord, and contact surface is little, and wind resistance is poor, causes stock to be moved by force unbalance in operation process, and stability and safety are not fine.
Utility model content
The purpose of this utility model is: in the high pier over-form construction of prior art, reinforcement installation colligation move stock form of structure and with the connected mode of fixedly turning over mould section or pier shaft, less stable, wind resistance and the poor performance of bearing out-of-balance force, safety is not fine, this patent, by changing structure and the mounting means of stock, improves stability and the safety of stock.
The purpose of this utility model is realized by following technical proposals:
A kind of high pier over-form construction reinforced bar installs mobile stock, comprise collar tie beam, column, platform beams, diagonal brace, shield posts, protection level railing, platform springboard and stock move suspension hook, described collar tie beam comprises and is supported in top layer around pier shaft and turns over support collar tie beam on mould template adpting flange plate, and correspondence is located at the top beam above support base collar tie beam, described column is spaced along pier shaft and is connected between support base collar tie beam and top beam, on described column, be fixed with described platform beams respectively down, and be also connected with described diagonal brace between lower platform crossbeam and column, on, lower platform crossbeam is supported with respectively described platform springboard, on, lower platform crossbeam is connected with shield posts between outer end, protection level railing is provided with between shield posts, column top described in some is also provided with described stock and moves suspension hook.
As selection, bottom described support collar tie beam, loopful and top layer turn over mould template adpting flange plate and contact, and the inside casing size supporting collar tie beam is large compared with pier shaft cross section, and housing edge is large compared with turning over mould flanged plate, while column comparatively support at the bottom of collar tie beam and extend downwards.
