Beam reinforcement label detail drawing

A, stirrup representation:

1 and φ 10@ 100/200(2) indicate that the stirrup is φ 10, the spacing between the encrypted areas is 100, and the spacing between the unencrypted areas is 200, all of which are double-arm seals.

2.φ 10 @ 100/200(4) indicates that the stirrup is φ 10, the spacing between encrypted areas is 100, and the spacing between unencrypted areas is 200, all of which are four-legged hoops.

3. Φ 8 @ 200 (2) indicates that the stirrup is Φ 8, with a spacing of 200, with leg hoops.

4. Φ 8 @ 100 (4)/150 (2) indicates that the stirrup is Φ 8, the spacing between the encrypted areas is100, the spacing between the four-legged hoops is150, and the spacing between the non-encrypted areas is two-legged hoops.

Second, the main reinforcement on the beam and the main reinforcement under the beam appear at the same time:

1, 3φ 22, 3φ 20 means that the upper reinforcement is 3φ 22 and the lower reinforcement is 3φ 20.

2.2φ 12 and 3 φ 18 indicate that the upper reinforcement is 2φ 12 and the lower reinforcement is 3 φ 18. ?

3,4 φ 25,4 φ 25 means that the upper reinforcement is 4 φ 25 and the lower reinforcement is 4 φ 25. ?

4.3 φ 25 and 5 φ 25 indicate that the upper reinforcement is 3 φ 25 and the lower reinforcement is 5 φ 25.

3. Representation method of steel bars on the upper part of the beam: (marked on the upper support of the beam)

1 and 2 Φ 20 indicate two Φ 20 steel bars, which are arranged in length and used for leg hoops. ?

2.2 φ 22+(4φ 12) means that 2 φ 22 is the total length, and 4φ 12 is used to erect the six-limb hoop upright.

3.6 Φ 25 4/2 means that the upper row of steel bars is 4 Φ 25 and the lower row is 2 Φ 25. ?

4.2 Φ 22+2 Φ 22 means that there is only one row of steel bars, two in the corner and two in the middle, evenly arranged.

Four, beam waist reinforcement representation:

1, G2φ 12 indicates the structural reinforcement on both sides of the beam, with one φ 12 on each side. ?

2.G4 φ 14 indicates the structural reinforcement on both sides of the beam, with two φ 14 on each side. ?

3.N2 φ 22 indicates the torsion bars on both sides of the beam, with one φ 22 on each side. ?

4.N4 φ 18 indicates the torsion reinforcement on both sides of the beam, with two φ 18 on each side.
