Embodiment 1

[0029] like Figure 1-7 As shown in the figure, the present invention provides a shaping formwork for a box girder steel frame, including a formwork base 1, a reinforcing bar positioning frame 3 and a base 6, the formwork base 1 includes a base body 11, and the side surface of the base body 11 is connected to the base 6. The side of the base 6 is fixedly connected, the interior of the pedestal body 11 is movably installed with a moving plate 14, the upper surface of the moving plate 14 is fixedly connected with the bottom surface of the reinforcing bar locating frame 3, and the upper surface of the moving plate 14 is fixedly installed on the reinforcing bar locating frame 3. The conveying pipe fixing rod 5 on the left side, the steel conveying pipe 4 is fixedly installed on the conveying pipe fixing rod 5, and one end of the steel conveying pipe 4 extends to the inside of the reinforcement positioning frame 3 and is fixedly connected with the steel reinforcement positioning fra...

Embodiment 2

[0034] like Figure 1-7 As shown, on the basis of Embodiment 1, the present invention provides a technical solution: preferably, the side surface of the moving plate 14 is movably connected with the side surface of the base 6, and the bottom surface of the moving plate 14 is fixedly installed with traveling wheels, and the traveling wheels are evenly distributed On the bottom surface of the moving plate 14, the bottom surface of the inner cavity of the pedestal body 11 is provided with a moving groove 13, and the moving groove 13 is slidably connected with the traveling wheel. The expansion and contraction of the hydraulic system 12 cooperates with the traveling wheels on the bottom surface of the moving plate 14 to slide in the moving groove 13, so that the moving plate 14 uses the expansion and contraction of the hydraulic system 12 to move toward the base body 11, so that the steel bars are separated from the steel bar conveying pipes 4, and the removal is completed. It avo...

Embodiment 3

[0036] like Figure 1-7 As shown, on the basis of Embodiment 1, the present invention provides a technical solution: preferably, a top beam 31 is fixedly installed on the top of the rebar positioning frame 3, and a bottom beam 61 is fixedly installed on both ends of the upper surface of the base 6, and the base The upper surface of 6 is fixedly installed with a bottom reinforcement pad 62, the bottom reinforcement pad 62 is symmetrically arranged with respect to the center line of the base 6, and a bottom reinforcement groove 621 is opened on the upper surface of the bottom reinforcement pad 62, and the bottom reinforcement slot 621 is evenly distributed on the bottom surface. On the upper surface of the reinforcing steel backing plate 62, the inner surface of the reinforcing steel conveying pipe 4 is provided with a roller groove 41, the number of the roller grooves 41 is several, and the several roller grooves 41 are evenly distributed on the inner wall of the reinforcing ste...

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...
