钢筋最基础的 最重要的知识（The most basic and important knowledge of steel bars） Said method, stirrup: The diameter of 10@100/200 (2) said the stirrup is 10, 100 non encrypted encryption area space, area distance of 200, all double hoop. The diameter of 10@100/200 (4) said the stirrup is 10, 100 non encrypted encryption area space, area distance of 200, all limbs hoop. The diameter of 8@200 (2) said the stirrup is 8, double hoop spacing is 200. The diameter of 8@100 (4) /150 (2) said the stirrup is 8, the encryption interval of 100 limbs hoop, non encrypted area spacing 150, double hoop. At the same time, a method of said beam main reinforcement and beam main reinforcement: The 3 Phi 22, Phi 20 3 3 22 with said upper bar, lower reinforced 3 phi 20. The 2 Phi 12, Phi 18 3 2 12 said the upper bar, lower reinforced 3 phi 18. The 4 Phi 25, Phi 25 4 4 25 with said upper bar, lower reinforced 4 phi 25. The 3 Phi 25, Phi 25 5 3 25 with said upper bar, lower reinforced 5 phi 25. Said method, two (standard support: upper beam reinforcement in the beam section) The 2 said the two Phi 20 Phi 20 steel, a long pass arrangement for double hoop. The 2 22+ (4 Phi Phi 12) said 2 to 4 with a diameter of 22 mm long, with 12 erect steel hoop for six. The 6 Phi 25 4/2 said 4 reinforced the upper upper row of 2 Phi 25, Phi 25. The 2 phi 22+ Phi 22 2 said only one row of steel bars, two in the corner, two in the middle, uniform layout. Three, Liang Yaozhong said the method of reinforcement: The G2 said the structure of reinforced beam with 12 sides, each side of a diameter of 12. The G4 said the structure of phi 14 reinforced beams on both sides, each side two phi 14. The N2 said on both sides of the beam diameter of 22 torsion bars, each side of a diameter of 22. The N4 said on both sides of the beam diameter of 18 torsion bars, each side two phi 18. Said method four, the lower part of steel beams: (lower standard in beam) The 4 Phi 25 said only one row of the main reinforcement, 4 Phi 25 all extende
