Abstract
The utility model relates to the field of bridge construction, in particular to a bridge hollow high pier internal formwork simple working platform. The bridge hollow high pier internal formwork simple working platform solves the problems that work amount of erecting steel pipe scaffolds is large, cost is high, disassembly and assembly difficulty is large, builders climb up a pier and climb down the pier inconveniently and the like in existing construction. The bridge hollow high pier internal formwork simple working platform comprises reserved installation holes arranged in two side walls of a pier body, and positioning bars inserted in the reserved installation holes in a penetrating mode. Horizontal supports close to the two side walls of the pier body and perpendicular to the longitudinal center line of a bridge are erected on the positioning bars, two horizontal supports are provided with longitudinal supports at intervals, a lower operating platform is paved on the longitudinal supports and provided with an integrated type steel pipe scaffold, and an upper operating platform is arranged on the top of the integrated type steel pipe scaffold. According to the bridge hollow high pier internal formwork simple working platform, work amount of the scaffolds is small, the cost is low, operation is simple and convenient, construction is quick, the builders can climb up the pier and climb down the pier conveniently, structural design is reasonable, use is convenient, application range is wide, installation speed and climbing speed are quick, and the bridge hollow high pier internal formwork simple working platform has high application value and wide application prospect.
Description
Technical field
The utility model relates to technical field of bridge construction, is specially the simple and easy working platform of a kind of bridge Hollow High Pier internal mold.
Background technology
The variable cross-section high pier is modal substructure form in mountainous area highway and the railroad bridge, and is more common when particularly bridge construction is higher, and two kinds of forms of the solid high pier of nonuniform thin-walled hollow pier and variable cross-section are generally arranged.For the internal mold construction of nonuniform thin-walled hollow pier, its traditional method is to set up steel pipe scaffold from the bottom to the top in pier, until pier construction is complete, remove again scaffold, there is following problem in this way in practice of construction, and 1, to set up the steel pipe scaffold engineering quantity large, cost is high; 2, dismounting difficulty is large; 3, pier is inconvenient about the constructor.
Summary of the invention
The utility model exist when solving existing bridge hollow pier internal mold construction set up that the steel pipe scaffold engineering quantity is large, cost is high, the dismounting difficulty large, constructor's problem such as pier inconvenience up and down, provide a kind of bridge Hollow High Pier internal mold simple and easy working platform.
The utility model is to adopt following technical scheme to realize: the simple and easy working platform of bridge Hollow High Pier internal mold, comprising that the interval is symmetricly set on the reserving installation hole of pier shaft two side and runs through is plugged in the reserving installation hole, and an end exposes the locating bar in the pier, locating bar is added to be provided with respectively near the pier shaft two side, and the horizontal support vertical with the bridge longitudinal centre line, space-stop rack is provided with the longitudinal carrier with bridge longitudinal center line parallel on two horizontal supports, be equipped with the bottom operating platform on the longitudinal carrier, the integrated steel tube scaffold identical with one-time-concreting concrete height is installed on the operating platform of bottom, and integrated steel tube scaffold top is provided with the upper operating platform.
Be provided with jacking between described integrated steel tube scaffold and the upper operating platform, jacking is used for adjusting the levelness of upper operating platform.
Adopt structure design of the present utility model, in pier shaft, set up by the bottom operating platform, the internal mold working platform of the reusable edible that integrated steel tube scaffold and upper operating platform consist of, this working platform can along with pier shaft build the height rising and constantly climb, utilize tower crane whole to promote up and down operating platform and steel pipe scaffold, so circulation, until finish the construction of whole pier shaft, wherein be convenient to tie up reinforcing bar and vertical internal mold at the bottom operating platform, according to one-time-concreting concrete height, establish the integrated steel tube scaffold that not dismounting can be recycled thereon, the scaffolding steel pipe top is upper by behind the jacking adjustment height, set up the upper operating platform, be convenient to tie up reinforcing bar, found internal mold and lay distributing device, concreting, by practical proof, the utlity model has following advantage:
1, do not need to set up steel pipe scaffold from the bottom to the top in pier, only need according to the disposable integrated steel tube scaffold of setting up of one-time-concreting concrete height, the scaffolding work amount is little, and cost is low;
2, the workman operates at the upper and lower part operating platform, and is time saving and energy saving, easy and simple to handle, and construction fast;
3, constantly rise owing to whole working platform, pier inner platform lower space can in time apply permanent spireme cat ladder in the pier by design, like this pier about the constructability personnel.
In a word, the utility model reasonable in design, easy to use, applied widely, the hollow pier of all compound sections all can adopt this working platform to carry out the internal mold construction, and installation rate is fast, climbing speed is fast, has higher using value and comparatively wide application prospect.
