Detailed Product Description: | Reinforced concrete pavement with a minimum diameter of steel mesh 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, transverse reinforcement spacing should not exceed 300mm. The vertical and horizontal steel mesh reinforcement should adopt the same diameter, 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, the bridge has a slab, the slab should be provided between the laminate and the concrete surface 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, 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. |
