What are the standard practices for reinforcement construction?
WALL COLUMN REINFORCEMENT LIMBING REINFORCEMENT REQUIREMENTS, LEVEL (stirrup) REINFORCEMENT SPACING MEETINGER DESIGN REQUIREMENTS, LEVEL REINFORCEMENT OR stirrup and each main reinforcement shall be bound in place, and jumping binding is prohibited.
1, wall column steel binding requirements line binding, horizontal (stirrup) steel spacing to meet the design requirements, horizontal reinforcement or stirrup and each main reinforcement intersection position binding in place, it is strictly prohibited to jump binding
2. Before pouring concrete, it is recommended to use PVC pipe to protect the main reinforcement from pollution; if no protection is taken, special personnel shall be assigned to clean it in time.
3. Stirrup shall be added at 500mm from the pouring plate surface, and the main reinforcement of the fixed column shall be offset.
4. Reinforcement diameter of wall and column ≥ 20mm, with mechanical joint
5. Reinforcement diameter of wall and column <20mm, electroslag pressure welding
6. Stirrup in the column core area: processed and welded into a reinforcement cage as shown in the figure, and the beam reinforcement will sink to the predetermined position when the binding is completed.
7, beam reinforcement binding main reinforcement spacing distribution is uniform, stirrup binding in place (stirrup and each main reinforcement intersection position must be effectively bound firmly)
8, beam main reinforcement diameter ≥ 20mm, using mechanical joints; beam main reinforcement <20mm using welding or binding lap
9. At the junction of primary and secondary beams, the stirrup in the direction of the main beam shall be bound at the junction position according to the spacing of the design drawings.
10. Beam and column stirrups shall be bent into an angle of 135 degrees according to seismic requirements.
11, beam reinforcement a row of reinforcement and two rows of reinforcement are separated by separating reinforcement, the diameter of the separating reinforcement is ≥ the diameter of the main reinforcement or 25mm; Separating bars are set at 500mm from the edge of the support, and one bar is set every 3m in the middle.
