Description

Technical Field

[0001] The utility model relates to the field of mounting bracket construction devices, in particular to a super-thick foundation bottom plate steel bar layered mounting bracket construction device. Background Art

[0002] For building foundation with thick slab, horizontal steel mesh is usually designed with multiple layers including upper, middle and lower layers. The installation and binding of steel bars shall be carried out layer by layer from bottom to top. After the installation and binding of the next layer of steel bars is completed, brackets shall be set for the previous layer of steel bars to form a stable support for each layer of steel mesh and prevent collapse accidents during the installation and binding of steel bars and concrete pouring.

[0003] The current support method is to provide support by setting steel stirrups at the bottom of each layer of steel mesh or to use steel sections to set vertical pillars and horizontal cross bars to form a support frame, and lay horizontal steel mesh on the frame.
