Interpretation of centralized marking of steel bars

JZL2(5)600 * 1000y: foundation beam, the number of beams is 2,5 spans, the width of beam is 600, the height of beam is 1000, with waist beam.

φ 10 @ 200(4): spacing of stirrup φ 10 is 200, with 4 limb hoops.

B4φ25； T2φ 18+4φ 16:4φ25 lower reinforcement; Upper reinforcement 2 φ 18+4 φ 16.

n4φ 16； Lφ8@400: There are four torsion bars on the side, 16, and the lacing spacing is 400.

yφ20 @ 250； Φ 8 @ 300: The distance between bottom reinforcement 20 and stirrup 8 is 250 and 300 respectively.

For the longitudinal reinforcement on the upper part of the beam bracket, when there are multiple rows of longitudinal reinforcement on the upper part of the beam bracket, each row of longitudinal reinforcement is separated from top to bottom with diagonal lines "/".

When the longitudinal reinforcement in the same row has two diameters, connect the longitudinal reinforcement with the plus sign "+",and write the corner longitudinal reinforcement in front.

There are four longitudinal bars in the upper part of the beam support, with 2φ 25 in the corner and 2φ 22 in the middle. The upper part of beam support should be marked as 2φ 25+2φ 22.

When the upper longitudinal bars on both sides of the middle bearing of the beam are different, they should be marked on both sides of the bearing respectively; When the upper longitudinal bars on both sides of the middle support of the beam are the same, the reinforcement value can be marked only on one side of the support, and the other side can be omitted.
