The construction method of steel bar framework of box beam overall binding, integral hoisting is characterized in that this construction method comprises the steps:
One, outer loose tool top cross bar is welded on the top of outer loose tool vertical rod, the lower end of outer loose tool brace is connected with bolt with outer loose tool brace lower fulcrum plate, the upper end of outer loose tool brace is with in the loose tool vertical rod outside of outer loose tool brace stull bolt, and the lower end of outer loose tool vertical rod is all fixing with the welding of loose tool rod member built-in fitting;
Two, inner die vertical rod short sleeve is welded on the loose tool vertical rod built-in fitting, the inner die vertical rod is inserted in the inner die vertical rod short sleeve, and the inner die cross bar is linked to be integral body by inner die vertical pole and inner die vertical rod, forms the inner die travel(l)ing rest;
Three, the upper end that will lack drag-line and long drag-line is fixed on the lifting shoulder pole that is welded by shaped steel, and the steel pipe below the top layer reinforcing bar that the lower end of short drag-line and long drag-line is passed the top layer reinforcing bar 15 of top board and base plate respectively tangles is sling whole framework of steel reinforcement.
Advantage of the present utility model:
What 1), reinforcing bar binding inner tube of a tyre mould bases adopted is to install and remove travel(l)ing rest fast, after finishing, installs the base plate reinforcing bar binding during construction, remove before the lifting, make top board reinforcing bar and base plate and web reinforcement on the loose tool frame once colligation become whole, can guarantee the globality of framework of steel reinforcement structure and the accuracy of positioning control, the time that the reinforcing bar binding operation is taken on precast pedestal is the shortest, and easy to operate, quick again.
2), reinforcing bar binding inner tube of a tyre mould bases is pin-connected panel, vertical rod was directly inserted and is arranged in the short sleeve of case beam spilled water hole position when inner die was installed, and did not clash with case beam base arrangement reinforcing bar, install simple, remove rapidly, occupied ground is little.
3), framework of steel reinforcement hangs many drag-lines by the lifting shoulder pole, tangle the steel pipe under the top layer reinforcing bar, steel pipe plays the distribution beam action, thereby steel bar framework of box beam weight is hung on the steel pipe, neither increase the elevating capacity of lifting appliance, make the bulk deformation of framework of steel reinforcement and local deformation reach minimum again.
