Shaping formwork for box girder reinforcement cage

Abstract

The invention discloses a shaping formwork for a box girder steel reinforcement framework, and relates to the technical field of shaping formworks. The shaping formwork comprises a formwork pedestal, a steel reinforcement positioning frame and a base, the formwork pedestal comprises a pedestal body, the side face of the pedestal body is fixedly connected with the side face of the base, and a movable plate is movably installed in the pedestal body; and the upper surface of the movable plate is fixedly connected with the bottom surface of the steel reinforcement positioning frame. An output shaft of a motor rotates to drive a driving gear to rotate, a rotating shaft rotates through meshing connection of the driving gear and a driven gear, then a drive wheel and a first rolling wheel are matched to drive reinforcing steel bars in a reinforcing steel bar conveying groove to move, reinforcing steel bar conveying is completed, and the problems that a box girder is larger in size, the mass of needed reinforcing steel bars is extremely large, manual feeding wastes manpower and material resources, meanwhile, great inconvenience exists, time of workers is wasted, and the production efficiency is reduced are solved, so that the effects of saving the time of the workers and improving the production efficiency are achieved.

Description

technical field [0001] The invention relates to a shaping formwork, and relates to the technical field of shaping formwork, in particular to a shaping formwork used for a box girder steel skeleton. Background technique [0002] The traditional prefabricated box girder steel bar binding is usually to assemble the outer formwork first, then bind the bottom plate and web steel reinforcement in the formwork, then install the inner formwork, and finally carry out the roof reinforcement binding, and pour the concrete. The construction sequence is: install the side formwork and reinforce— Bottom and web steel reinforcement binding - bottom and web prestressed pipeline positioning and installation - installation of inner formwork - installation of anchor pads - top plate reinforcement binding - top plate prestressed pipeline positioning and installation - pouring concrete. [0003] The following problems exist for the prior art: [0004] 1. When using the stereotyped formwork to ma...

Problems solved by technology

[0006] The invention provides a shaped formwork for box girder reinforcement skeleton, one purpose of which is to have the ability of mechanical conveying and loading, so as to solve the problem that the volume of box girder is large, the required steel bar volume is huge, and manual loading is required. It is a waste of manpower and material resources, and at the same time there is a lot of inconvenience, resulting in a waste of workers' time and a reduction in production efficiency; another purpose is to solve the problem that the traditional stereotyped formwork needs to be disassembled after use to achieve demoulding, and frequent disassembly will cause problems. The joints of the shaped formwork are worn, resulting in a reduction in the service life of the shaped formwork and an increase in the cost of use, so as to improve the service life of the shaped formwork and reduce the cost of use
