Embodiment Construction

[0027] Attached below figure 1 to attach Image 6 The present invention will be further described.

[0028] The technical scheme that the present invention overcomes its technical problem adopts is:

[0029] The overall binding and hoisting construction method of the upward mobile formwork steel bar includes the following steps:

[0030] a) Concrete is poured at the reinforcement skeleton 18 in the outer formwork 22 to form a box girder; b) the poured box girder is subjected to equal-strength maintenance, tensioning, grouting and anchoring construction procedures; c) in step a) And while step b) is being constructed, a mold 4 is set on the concrete box girder that has been poured and formed in the previous hole, and the bottom plate reinforcement, web reinforcement, and prestressed steel of the next hole are bound on the mold 4 along the longitudinal direction. Bundle, assemble the inner mold, bind the roof reinforcement and pass the steel strands to finally form the steel ...

Abstract

The invention relates to an overall reinforcement binding and hoisting construction method and construction device adopting upstroke movable scaffolding. Concrete is poured in the position of a reinforcement cage in an external formwork to form a box girder; the poured box girder is subjected to construction procedures including equal-strength curing, tensioning, grouting and anchor sealing; meanwhile, a mold is arranged on the box girder poured in a former hole, and the reinforcement cage is bound on the mold in the longitudinal direction. Then the upstroke movable scaffolding passes a hole and moves the a next span, after adjustment in position, the reinforcement cage is conveyed to the upstroke movable scaffolding from inside of the mold and is hoisted to the external formwork through a hoisting device to realize synchronous operation, and the construction period for each hole can be shortened by about 5 days. Compared with the traditional construction process, the requirements for large span, large tonnage and high clearance are met, and the construction method and the construction device are also applicable to conditions that gantry crane traveling tracks cannot be arranged below a bridge surface for offshore construction and the like.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a construction method and a construction device for integrally binding and hoisting steel bars of an upward mobile formwork frame. Background technique [0002] The mobile formwork bridge building machine is a construction machine with its own formwork, which uses the cap or pier column as a support to pour the bridge on site. The construction process of the mobile formwork is a flow operation, and the steps are as follows: 1. Move the formwork through the hole and adjust it in place; 2. Bind the bottom, web steel bars, and arrange prestressed steel beams; 3. Assemble the inner mold; 4. Bind the top plate 5. Pouring box girder concrete; 6. Equal strength maintenance; 7. Tensioning, grouting, and anchor sealing. The construction period of each beam is about 18 days. The mobile formwork construction process must be completed before the next process can be carried out....
