Embodiment Construction

[0019] Shown in conjunction with accompanying drawing, the technical scheme of the present invention is further described:

[0020] A bridge girder slab hoisting and positioning steel bar precise placement technology, including positioning steel bar 1, a drum 2, the drum 2 is a hollow drum, and the drum 2 does not include a top surface and a bottom surface;

[0021] The precise placement technology of the positioning reinforcement includes the following steps:

[0022] S1: place the drum 2 at the fixed position where the steel bars need to be positioned;

[0023] S2: Pouring concrete into the drum 2 to fill up the drum 2;

[0024] S3: After the concrete fills the drum 2, quickly insert the steel bar 1 into the concrete of the drum 2, and the insertion position of the steel bar 1 is the position that needs to be accurately positioned.

[0025] In this embodiment, it is preferable to select the inner diameter of the drum 2 to be 5-10 cm, and the height of the drum body 2 to be...

Abstract

The invention discloses a bridge beam plate hoisting position steel bar accurate arrangement technology. The technology involves a position reinforcing steel bar and a circular barrel; the circular barrel is a hollow barrel, and the circular barrel does not comprise a top surface and a bottom surface; the positioning reinforcing steel bar accurate placement technology comprises the following stepsS1, the circular barrel is placed at a position where the position reinforcing steel bar needs to be fixed; S2, concrete is poured into the circular barrel, and the circular barrel is filled with theconcrete; and S3, after the circular barrel is filled with the concrete, the reinforcing steel bar is rapidly inserted into the concrete in the circular barrel, and the insertion position of the reinforcing steel bar is the position needing to be accurately positioned. According to the technology, a pre-buried sleeve is used for positioning during pouring and the position reinforcing steel bar isaccurately arranged after pouring so that the position reinforcing steel bar can be effectively and accurately arranged, and the beam plate can be smoothly hoisted and arranged.

Description

technical field [0001] The invention belongs to the field of bridge engineering, and in particular relates to a technology for precise placement of steel bars for hoisting and positioning bridge girder slabs. Background technique [0002] The traditional beam slab positioning reinforcement is welded to the steel mesh before pouring the cap and cover beam. Due to the deviation during the pouring process, the position of the reinforcement and the beam slab collides during hoisting. Utilizing the technology of pre-embedded sleeve positioning during pouring and accurately positioning the positioning reinforcement after pouring, the positioning reinforcement can be effectively and accurately set to facilitate the smooth hoisting and installation of beams and slabs. [0003] The application number is: CN201621299559.X, the application date is: 20161130, and the name is: a precise placement technology for hoisting and positioning steel bars of bridge beams and slabs. The accuracy ...
