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?

　　橋梁鋼網(wǎng)鋪裝的主要順序是:安裝底網(wǎng)——附加墊網(wǎng)或鋼筋安裝——支撐面網(wǎng)鋪裝——垂直和水平面網(wǎng)鋪裝——附加網(wǎng)和鋼筋安裝。

　　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.

　　在鋪設(shè)底網(wǎng)時，應(yīng)注意主應(yīng)力桿應(yīng)位于網(wǎng)的底部，而在鋪設(shè)面網(wǎng)時，主應(yīng)力桿應(yīng)位于網(wǎng)的頂部。

　　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.

　　相鄰兩個網(wǎng)片重疊時，應(yīng)在重疊區(qū)域的中心和兩端牢固地使用鋼絲綁扎，綁扎點不得少于3個。每一個與附加鋼筋和焊接網(wǎng)連接的節(jié)點都應(yīng)用鐵絲固定牢固。

　　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.

　　充分墊馬凳和墊塊，確保鋼筋在混凝土保護(hù)層的厚度和尺寸。

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

　　鋼網(wǎng)是由縱向和橫向的鋼筋通過捆綁或焊接交叉而成。是建設(shè)部“2005年建筑業(yè)10項新技術(shù)推廣應(yīng)用”的內(nèi)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".

　　鋼筋網(wǎng)理論重量計算公式:

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

　　網(wǎng)孔理論重量(KG) =網(wǎng)孔所用鋼筋長度(M)*鋼絲直徑(MM)*鋼絲直徑(MM)*0.00617(參數(shù)10根鋼筋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)

　　鋼網(wǎng)應(yīng)用于梁柱樓板、屋面、墻體、混凝土路面、橋梁路面、機(jī)場跑道、隧道襯砌、箱體涵洞、碼頭樓板、預(yù)制構(gòu)件等領(lǐng)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.
