Steel bar planting-free construction method for constructional column steel bars

The invention relates to building construction, in particular to a constructional column steel bar planting-free construction method. The method comprises the following steps that S1, a steel plate is manufactured, and mounting holes are formed in the steel plate; s2, the sleeve is installed in the installation hole of the steel plate, and the sleeve and the steel plate form a steel plate assembly; s3, a steel plate assembly is placed, before main structure steel bars are bound, the steel plate assembly is placed at the installation position to serve as a protection layer cushion block, and after the main structure steel bars are bound, the steel plate assembly is installed again; s4, main body structure concrete pouring; s5, steel bar threading; s6, the steel bars are installed in the sleeves; s7, carrying out a pull-out test; and S8, binding constructional column steel bars. The device is easy to manufacture, convenient to operate and capable of bearing higher tension, and the steel bar planting quality is
