Detailed Description
The present invention will be described in further detail with reference to examples and drawings, but embodiments of the present invention are not limited thereto.
Example 1:
in this embodiment, a construction method and structure of an embedded channel steel are provided, wherein the bottom surface of the embedded channel steel 1 faces a reinforcing mesh 5 for a designed wall, a screw rod 2 perpendicular to the embedded channel steel 1 is installed on the bottom surface of the embedded channel steel 1, a connecting steel bar 3 parallel to the screw rod 2 is installed at the free end of the screw rod 2, the thickness of the embedded channel steel 1, the sum of the length of the screw rod 2 and the length of the connecting steel bar 3 is equal to the thickness of the designed wall, and the installation position of the embedded channel steel 1 is controlled by connecting the connecting steel bar 3 with the reinforcing mesh 5.
During construction, the length of the connecting steel bars 3 is measured, the length of the connecting steel bars 3 needs to meet design requirements, lofting is carried out according to the distance and the height of the design requirements, the installation position of the connecting steel bars 3 is determined, and in the embodiment, the connecting steel bars 3 are welded with the steel bar meshes 5. After the connecting steel bars 3 are welded, the corresponding embedded channel steel 1 is installed, the corresponding screw rods 2 on the embedded channel steel 1 are aligned with the connecting steel bars 3, and then the screw rods 2 are welded with the connecting steel bars 3.
