How to check whether the steel mesh is qualified？

When the steel bars are thick and the welded mesh cannot be bent, the ends of the welded mesh can be welded with 1-2 less steel bars, and then the two ends can be pierced into the beam. Steel wire lashing should be used at each node where the additional steel bars are connected to the welded mesh.

There are two methods for the bottom mesh of the steel mesh: vertical reinforcement and cushion mesh. The surface mesh of the ribbed steel welded mesh should be flat lap joints. It should be set at a place where the force is small, and it is better to set it at a distance. Outside the 1/4 clear span section of the beam side, the lap length should not be less than 30dd as the lap direction, and the diameter of the steel bar should not be less than 250mm.

Between the ends of two welded meshes, the minimum lap length of the steel bar lap joint should not be less than 1.3 times the minimum anchoring length la, and should not be less than 200 mm. In the overlap area, the transverse reinforcement of each welded steel mesh shall not be The spacing between the outermost transverse reinforcement of less than one or two reinforcement meshes should not be less than 50 mm. When one of the two steel meshes in the overlap area has no transverse reinforcement, the minimum overlap length of the ribbed steel mesh should be 1.3 times the minimum anchoring length la, and should not be less than 300mm. When the diameter of the longitudinally stressed steel bar in the lap area is d≥10mm, the lap length should be increased by 5d.

Reinforcement mesh equipment future inspection method: The primary process of steel mesh paving is: the welded steel mesh must be positioned according to the design drawing-mesh equipment-mesh-check and check. The primary order of steel mesh paving is: equipment bottom net-additional mat or steel equipment-bearing surface net paving-vertical and horizontal surface net paving-additional net and steel equipment.
