Before the reinforcement mesh is laid, a reinforcement mesh placement plan should be drawn up. When the steel mesh is laid, it should be placed on the site according to the practical needs of the site. When the steel mesh is thin, the zigzag deformation function of the steel mesh can be used. Yes, the center part of the welded mesh is twisted so that both ends can pierce the beam, and then the mesh is laid.

When the steel mesh cannot be detoured, 1-2 steel bars can be welded at the end of the welded mesh, and then the two heads are inserted into the beam, and the straight bar method is used to select the on-site separation method. The connection of the cutting rod, the steel bar and the welded mesh should be selected for the connection of the wire rope. Use two methods to set the bottom mesh of the steel mesh and stop filling it.

The surface network of the two-way reinforcement of the welded steel mesh should be selected by the plane lap joint. It should be set on a lower force, it should be set on the 1/4 span section of the beam side, and the length of the loop should not be less than 30dd, and the diameter of the steel bar should not be less than the lap length of the small rebar lap joint Should not be less than 1.3 times the minimum anchorage length between the final two welded joints.

It should not be less than 200 for the lap area, and the interval between the transverse bars of each welded steel mesh sheet should not be less than 1, and the interval between the outer bars of the two steel mesh sheets should not be less than 50. The rib mesh When the length of the small lap should be 1.3 times the length of the small anchor, and should not be less than 300, one of the two steel mesh sheets in the lap belt is not laterally reinforced.

The main process of stencil paving is: the welded stencil should be positioned and screened according to the planning drawings. The order of steel mesh sheets is the bottom mesh of the equipment - additional buffer mesh or steel reinforcement - support surface network laying - vertical and horizontal surface network laying - additional network and reinforcement. When laying the bottom mesh, the main stress reinforcement should be located below the mesh. When laying the ground net, the required reinforcement will be placed on top of the net.
