The main purpose of steel binding construction is to effectively fix the formed steel bars in the corresponding parts according to the requirements of design drawings to form the design shape. In the process of construction, the following points should be noted:
1, the location (reinforcement type, molding size and reinforcement location) of the rebar shall be accurate and firm, and the concrete shall not be deformed due to vibration during pouring;
2, binding joint, joint position, joint distribution rate, reinforcement spacing, anchorage length, etc. Comply with the specifications and design requirements.
3. When binding steel bars, the protective layer pad must be placed according to the designed protective layer thickness, and it shall be firmly bound with steel bars without displacement.
4. When the steel bar is bound, the "eight-buckle" binding method is generally adopted to ensure that the steel bar is bound in place, and the long iron wire should be thrown inside to prevent people from sticking or being exposed after pouring concrete;
5, flat plate binding one-way plate can use "plum blossom" binding method, but the edge of the plate should be not less than two strong binding, two-way plate should be strong binding.
