Steel mesh reinforced concrete pavement on the application of reinforced concrete pavement with steel mesh minimum diameter and the maximum spacing should be consistent with existing industry standard "Highway Cement Concrete Pavement Design Specification" JTG D40 requirements. When using cold-rolled ribbed steel mesh films, bar diameter not less than 8mm, longitudinal reinforcement spacing should not exceed 200mm steel mesh specifications, transverse reinforcement spacing should not exceed 300mm. The vertical and horizontal steel mesh reinforcement should adopt the same diameter steel mesh, reinforced protective layer thickness of not less than 50mm. Reinforced concrete pavement reinforcement steel mesh can be reinforced with steel mesh concrete pavement of the relevant regulations. 1, concrete pavement structures with fixed dovetail joints expansion dowel bar can not be set, it would be adjacent to the ends of the inner structures of the plate with bunk steel mesh; or a length of about 6 to 10 times the thickness range thickness gradually increased by 20%. 2, concrete pavement and bridge phase, when high-quality slab bridge with steel mesh, and the concrete slab should be arranged between the surface laminates long 6 a 10mm steel mesh concrete surface transition board. When the bridge is of bias, the reinforced concrete slab should be part of an acute angle steel mesh reinforcement. 3, the surface layer of concrete structures under the box-shaped transverse cross, its top surface to the bottom surface or embedded grassroots distance of less than 400mm, the top width and both sides of the structures, concrete surface layer should be laid double steel mesh reinforcement mesh production process, steel mesh on the lower surface of each layer from the top and bottom 1/4 of a 1/3 of the thickness of the Department. Under the concrete surface with a circular transverse cross tubular structures, its top surface to the bottom surface when the distance is less than 1200mm, the structures on both sides, should be laid within the concrete surface layer steel mesh, steel mesh surface located at a distance top layer 1/4 - 1/3 the thickness at. From the industry standard "Highway Cement Concrete Pavement Design Specification" JTG D40-2002. Steel mesh the technical requirements of technical rules, welded mesh should adopt CRB550 grade cold-rolled ribbed steel production, may also CRB510 grade cold rolled smooth steel production. A welded mesh should adopt the same type of steel welded into. Welded mesh according to the shape, size is divided into two kinds of styling and customization. Welded mesh in both directions setting the bar spacing and diameter can vary, but in the same direction of the reinforcement should have the same diameter, pitch and length in the relevant standards, regulations and the requirements made. Custom welded shapes, sizes should be based on the design and construction requirements, combined with the specific project circumstances, negotiated by both parties. Welded mesh reinforcement diameter 4-14mm, which can be used to upgrade 0.5mm diameter. Consider transportation conditions, welded mesh length should not exceed 12m, the width should not exceed 3.4m. Welded steel production direction (or called longitudinal reinforcement) spacing appropriate for the 100,150,200 mm, in the other direction reinforcement spacing is generally 100,150,200,300 mm, sometimes up to 400mm. When the vertical and horizontal bars are welded single bar, the smaller nominal diameter of reinforcement should not be less than the nominal diameter thick reinforced 0.6 times that dmin ≥ 0.6damx. Welded joints shear force (in units of N) should not be less than 150 thick reinforced with nominal cross-sectional area (in units of mm2) of the product.
