Reinforcement net is mainly used for paving municipal bridges and highway bridges, rebuilding old bridges and crack resistance of piers. Through the quality inspection of thousands of bridges in China, the results show that the quality of deck pavement can be significantly improved by using welded steel bars. The qualified rate of protective layer thickness can reach more than 97%, the smoothness of bridge deck can be improved, there are almost no cracks on bridge deck, the paving speed has increased by more than 50%, and the cost of deck paving has been reduced by 10%. How is the steel mesh installed? What are the installation steps?

　　桥梁钢网铺装的主要顺序是:安装底网——附加垫网或钢筋安装——支撑面网铺装——垂直和水平面网铺装——附加网和钢筋安装。

　　The main sequence of bridge steel mesh pavement is: installation of bottom mesh - Additional cushion mesh or steel bar installation - support surface mesh pavement - vertical and horizontal mesh pavement - Additional mesh and steel bar installation.

　　在铺设底网时，应注意主应力杆应位于网的底部，而在铺设面网时，主应力杆应位于网的顶部。

　　When laying the bottom net, it should be noted that the main stress bar should be located at the bottom of the net, while when laying the surface net, the main stress bar should be located at the top of the net.

　　相邻两个网片重叠时，应在重叠区域的中心和两端牢固地使用钢丝绑扎，绑扎点不得少于3个。每一个与附加钢筋和焊接网连接的节点都应用铁丝固定牢固。

　　When two adjacent meshes overlap, steel wire should be firmly tied at the center and both ends of the overlapping area, and the binding points should not be less than three. Each joint connected with additional steel bar and welded wire shall be securely secured by wire.

　　充分垫马凳和垫块，确保钢筋在混凝土保护层的厚度和尺寸。

　　Fully cushion the horse stool and cushion block to ensure the thickness and size of the steel bar in the concrete protective layer.

　　钢网是由纵向和横向的钢筋通过捆绑或焊接交叉而成。是建设部“2005年建筑业10项新技术推广应用”的内容之一。

　　The steel mesh is made of longitudinal and transverse reinforcing bars which are bundled or welded together. It is one of the contents of the Ministry of Construction's "Promotion and Application of Ten New Technologies in Construction Industry in 2005".

　　钢筋网理论重量计算公式:

　　The formulas for calculating the theoretical weight of steel mesh are as follows:

　　网孔理论重量(KG) =网孔所用钢筋长度(M)*钢丝直径(MM)*钢丝直径(MM)*0.00617(参数10根钢筋0.616539 KG/M)

　　Mesh theoretical weight (KG) = length of reinforcement (M) * diameter of steel wire (MM) * diameter of steel wire (MM) * 0.00617 (parameter 10 bars 0.616539 KG/M)

　　钢网应用于梁柱楼板、屋面、墙体、混凝土路面、桥梁路面、机场跑道、隧道衬砌、箱体涵洞、码头楼板、预制构件等领域。

　　Steel mesh is used in beam-column floor, roof, wall, concrete pavement, bridge pavement, Airport runway, tunnel lining, box culvert, wharf floor, prefabricated components and other fields.
