2. Beam and slab <br>reinforcement construction 1. Beam reinforcement is usually tied after the beam bottom formwork is supported. After lashing, the side formwork is supported after inspection. The secondary beams with low cross-section (≤500) are not required. For this effect, the beams can be set up and tied, and then the beam tendons can be dropped. When the longitudinal reinforcement of the beam adopts two upper and lower layers, a 25mm diameter steel bar can be used between the two layers to maintain the row spacing of the upper and lower steel bars. The main and secondary beams should be connected with lifting reinforcement and stirrup reinforcement according to the design requirements. The joints of the ribs should be staggered on both sides of the beam, and the joint positions should meet the design requirements and be staggered. <br>3. The slab reinforcement should be constructed after the beam reinforcement is tied up. Before lashing, mark the template on the template according to the specifications required by the design. The hooks of the bottom steel bars should face up, and the hooks of the upper steel bars should face down and be anchored in the beam. For slabs with double ribs, foot supports should be added between the upper and lower ribs to ensure the distance between the two ribs. <br>4. At the intersection of beams, slabs, and columns, the steel bars are often dense, and it is difficult to mortar during concrete pouring. When tying the concrete, the amount should be measured to create conditions for the concrete pouring, and the spacing between the steel bars should be at least 30mm. To prevent the steel bars from being raised or pressed down during the pre-embedding of water and electric wires, pad blocks should be added as required before concrete pouring.

2. Beam, plate construction<br>1. Beam ribs are usually tied up after the beam bottom mold is well tied, tied after unsure and then side mold support, for the cross-section is not high (≤500) secondary beam can not be affected by this, the beam can be tied up, tied and then the beam ribs fall. When the beam vertical rebar adopts the upper and lower two layers, can be used in two layers between the pads with a diameter of 25mm of rebar, in order to maintain the rowing of the upper and lower rebar, the main secondary beam junction should be in accordance with the design requirements of the addition of lifting ribs and hoop encryption, the joints of the hoops should be staggered on both sides of the beam, the joint position should meet the design requirements and staggered with each other.<br>3. The ribs should be constructed after the beam ribs are tied, and the specifications of the design requirements are crossed on the template before the tie-up. The hook of the bottom rebar should be facing up, and the hook of the upper steel bar should be facing down and anchored in the beam. For double-layered ribs, foot support should be added between the upper and lower ribs to ensure the spacing of the two-layer ribs.<br>4. At the intersection of beams, plates and columns, often the rebar is denser, the concrete pouring is difficult, the amount of the concrete should be tied to create conditions for concrete pouring, so that the bar spacing at least 30mm spacing, the beam plate is tied, should prevent the water wire pipe pre-buried when the rebar is raised or pressed down, before concrete pouring according to the requirements of the pad block.

Beam and slab reinforcement<br>1. The beam reinforcement is usually bound after the beam bottom formwork is supported, and the side formwork support can be carried out after the binding is checked to be correct. The secondary beam with low section (≤ 500) can not be affected by this. The beam can be lifted and bound, and the beam reinforcement can be dropped after binding. When the longitudinal reinforcement of beam adopts upper and lower layers, the reinforcement with diameter of 25 mm can be padded between the two layers to maintain the row spacing of upper and lower reinforcement. Hanging bars and stirrups shall be added at the junction of primary and secondary beams according to the design requirements. The joints of stirrups shall be staggered on both sides of the beam, and the joint position shall meet the design requirements and be staggered.<br>3. The plate reinforcement shall be constructed after the beam reinforcement is bound, and the line shall be drawn on the formwork according to the design requirements before binding. The hook of bottom reinforcement shall face upward, and the hook of upper reinforcement shall face downward and be anchored in the beam. For the slab with double-layer reinforcement, the foot brace should be added between the upper and lower reinforcement to ensure the spacing between the two layers of reinforcement.<br>4. At the intersection of beam, slab and column, the reinforcement is often dense, and it is difficult to pour the concrete during concrete pouring. During the binding, it is necessary to create conditions for concrete pouring, so that the spacing of steel bars is at least 30mm. After the binding of beam and slab reinforcement, it is necessary to prevent the reinforcement from being raised or pressed down when the water and electricity pipelines are embedded. Cushion blocks shall be added before concrete pouring.<br>
