Embodiment Construction

[0064] The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing:

[0065] like Figure 1~Figure 10 As shown, the precision positioning and fixing device for pre-embedded steel bars in the cast-in-place bottom plate of the side wall of the prefabricated trench includes the lower horizontal positioning and fixing frame, the middle level horizontal positioning and fixing frame and the upper level horizontal positioning and fixing verification set that are arranged in sequence from bottom to top Board and eight uprights 1. The vertical rod 1 is used to connect the lower level horizontal positioning fixed frame, the middle level horizontal positioning fixed frame and the upper level horizontal positioning fixed verification cover plate in sequence, and after the connection, a rectangular three-dimensional frame structure device is formed together.

[0066] The precision positioning and fixing device is a rectangular thr...

Abstract

The invention relates to a precise positioning and fixing device for embedded steel bars in a cast-in-place bottom plate of a fabricated channel side wall. The precise positioning and fixing device comprises a lower-layer horizontal positioning and fixing frame, a middle-layer horizontal positioning and fixing frame, an upper-layer horizontal positioning and fixing verification sleeve plate and a plurality of vertical rods. The lower-layer horizontal positioning and fixing frame comprises two fixing frame long rods, a positioning toothed plate strip and a plurality of transverse rods; the middle-layer horizontal positioning and fixing frame and the lower-layer horizontal positioning and fixing frame are the same in structure; the vertical rods are arranged between the middle-layer horizontal positioning and fixing frame and the lower-layer horizontal positioning and fixing frame; and the upper-layer horizontal positioning and fixing verification sleeve plate is correspondingly arranged above the middle-layer horizontal positioning and fixing frame, and the top ends of the vertical rods exceed the upper-layer horizontal positioning and fixing verification sleeve plate. The invention further relates to a construction method of the precise positioning and fixing device for the embedded steel bars in the cast-in-place bottom plate of the fabricated channel side wall. The problems that in the construction process of cast-in-place bottom plate pre-embedded vertical steel bars, the positioning deviation is large, binding is loose, and fixing is not firm can be solved.

Description

technical field [0001] The invention relates to the technical field of water conservancy and building construction, in particular to a precision positioning and fixing device and construction method for pre-embedded steel bars in the cast-in-place bottom plate of the side wall of an assembled trench. Background technique [0002] The existing prefabricated trench adopts prefabricated and cast-in-place hybrid prefabricated structure and construction method. Reinforced concrete side walls are prefabricated in the factory and reinforced concrete for the cast-in-place floor is carried out at the construction site, and then prefabricated on the poured concrete floor. Assembly and installation of side walls, assembled into reinforced concrete trenches. [0003] During the construction of the prefabricated trench, there is a structural connection problem between the steel bars between the cast-in-place base plate and the fabricated side wall, which requires the installation of pre-...
