The main laying steps of the steel mesh are: first of all, to install the design drawing to place and position, followed by the installation of the steel mesh, again is the mesh, and then is to check and accept it.
The installation of the bottom net, followed by the installation of reinforcement and cushion net, again is the installation of the bearing surface net, and the vertical and horizontal direction of the surface net installation, and then again the installation of the net and reinforcement. When installing the bottom net, there are several points that need special attention. First of all, the main reinforcement should be installed below the net. When laying the surface net, the main reinforcement should be installed above the net.
If two adjacent mesh between the need to build, in the lap of the center position should be tied and fixed with wire, binding points can not be less than three. The role of wire mesh in exterior wall plastering is mainly a measure to prevent falling off from a safety point of view, and the role of anti-cracking is relatively small, because of the position of the problem.
And for the external insulation system is used in the brick veneer, as for the role of the first should also be anti-shedding and anti-cracking, so it should choose the grid 0.6×10×10, the conversion of the grid from the specifications of the national provisions of the steel wire mesh, using the conversion of steel content.
Concrete structure, reinforced concrete is composed of two different material steel and concrete composite materials, two kinds of material has a good bonding performance is the basis of their common work, from the Angle of reinforced bond anchorage concrete cover request, is to ensure that the steel bar and its surrounding concrete can work together, and give full play to calculate the strength and steel.
