Reinforcing steel bar welded mesh

The utility model relates to a reinforcing steel bar welded mesh which belongs to the technical field of building materials. The reinforcing steel bar welded mesh comprises transverse reinforcing steel bars parallel to each other and vertical reinforcing steel bars parallel to each other. The transverse and vertical reinforcing steel bars are connected by welding. The strength of the reinforcing steel bar welded mesh is 210-380N/mm . According to the reinforcing steel bar welded mesh, joints among the transverse and vertical reinforcing steel bars are welded and fixed, so that the antis-slippage capacity of a composite floor is effectively improved. The vertical reinforcing steel bars are bonded with concrete to a great extent, so that slippage of concrete is effectively inhibited, and therefore, the bearing capacity of the composite floor is effectively improved.
