What are the main contents and construction techniques of column reinforcement binding?

What are the main contents and construction techniques of column reinforcement binding? The following Zhong Da consults the bidding teacher to answer your questions for your reference.

1, construction technology: erection of scaffold supported by column reinforcement → set of column stirrups → connection and binding of vertical reinforced bars → drawing stirrup spacing lines → binding stirrups.

2. Erection of scaffold supported by column rebar: the column rebar support frame is erected with scaffolding steel pipes, and springboard is laid around the working surface and safety net is hung.

3. Setting column stirrups: According to the spacing required by the drawings, calculate the number of stirrups for each column. First, set stirrups on the steel bars protruding from the lower layer, and then tie the positioning steel bars and column steel bars.

4. Mechanical connection: After the main reinforcement of vertical reinforced column is installed, the dimensions of mechanical connection joints and sleeves shall meet the requirements of design and relevant specifications.

5. Draw the stirrup spacing line: draw the stirrup spacing line with chalk on the vertical bar of the column that has been erected.

6. Column stirrup binding: The joints of stirrups (where hooks overlap) should be staggered on the longitudinal reinforcing bars at the four corners. Column corner reinforcing bars and stirrups should be staggered and fastened with double buckles, and the fastening buckles should be splayed with each other. Stirrups should be perpendicular to the main reinforcement.

7, the lower vertical exposed floor with column hoop fixed.

8. Cross-section change: The exposed part of the lower column rebar should shrink accurately before binding the upper beam.

9, the main reinforcement processing.

10, thickness of protective layer: it meets the design and specification requirements, and adopts column positioning ribs.
