Construction project: construction plan of reinforcing steel works

Reinforcement is one of the essential building materials in construction engineering. To save steel building materials and ensure construction quality, it is necessary to have a perfect steel construction plan. The original intention of the plan is to better handle the details and implement the actual operation. . So how do you do the construction of the steel works?

1. Steel Processing

(1) Processing of steel raw materials

1) Processing strictly according to the single batching of steel bars: determining the bending adjustment value, bending hook increase length, stirrup adjustment value and other parameters to ensure that the length of blanking is accurate;

Rebar rust removal: Rebar should be rust removal before cutting, the surface of the steel bar grease stains, paint stains and floating skin, rust and other clean, so as not to affect its bond with concrete effect;

2) Straightening of reinforcing steel bar: the cold drawing ratio of the steel bar straightened by hoist is not more than 4% for Grade I steel and less than 1% for Grade II steel.

3) steel bar cutting: steel bar cutting machine should be used according to its diameter and steel bar grade and other factors to determine the use of steel bar cutting operation, cutting the same specification of steel bar according to the length of different combinations, overall layout, first cut long material, then cut short material, reduce short head, reduce loss, cut length allowable error of 5 mm;
