1. Segmentation (blocks) of steel mesh and steel skeleton should be determined according to the structural reinforcement characteristics and lifting capacity. Generally, the area of steel mesh should be 6 ~ 20m2, and the length of steel frame should be 6 ~ 12m.
2. Temporary reinforcement measures should be taken to prevent skewed deformation during transportation and installation. Fig. 9-121 is the temporary reinforcement of steel mesh.
3. The hanging points of steel mesh and steel frame should be determined according to their size, weight and stiffness. Horizontal steel mesh with width greater than 1 m should be lifted by four points; steel skeleton with span less than 6 m should be lifted by two points; steel skeleton with large span and poor stiffness should be lifted by four points of cross hanger beam (iron flat pole). In order to prevent the stress and deformation of the steel bar at the hanging point, the bottom hoisting or the shortening of the steel bar can be adopted.
4. The method of bonding the joint of steel mesh and steel skeleton is the same as that of bonding steel reinforcement on site.

鋼筋焊接網的鋼筋標準：產品精度高,誤差小,質量好等特點,鋼筋網是一種焊接成型的網狀鋼筋制品，是縱向和橫向鋼筋分別以一定的間距排列且互成直角，全部交叉點均用強電阻壓力熔焊在一起的鋼筋網片。鋼筋是根據社會生產需要而制訂出的材料標準，它的屈服強度、極限強度、延伸率、冷彎及可焊性均有很大的不同，不同級別的鋼筋使用位置也有很大的不同。一級鋼屈服強度235MPa，極限強度310MPa，二級鋼屈服強度335MPa，極限強度510MPa，三級鋼屈服強度400MPa，極限強度600MPa。所以鋼筋網所用的鋼筋為三級鋼冷軋CRB550材質?，F在生產的鋼筋焊接網大部分是用于橋面的鋪設 大家都知道近幾年來橋面的垮塌事故經常性的發生 造成不可估計的財產損失 所以橋面所用的鋼筋網固然也很重要 一些小的作坊廠子在做的時候質量不合格 偷梁換柱安裝上去留有一定的安全隱患 鋼筋網所用的規格尺寸均按標準設計 所以鋼筋網的質量一定嚴格按標準設計的規格尺寸生產。
Reinforcement standard of welded reinforcing steel mesh: high precision, small error, good quality and so on. Reinforcing steel mesh is a kind of welded net-shaped reinforcing steel products. It is a reinforcing steel mesh with longitudinal and transverse reinforcing bars arranged at a certain distance and at right angles to each other. All intersections are welded together by strong resistance pressure. Reinforcement bar is a material standard formulated by the state according to the needs of social production. Its yield strength, ultimate strength, elongation, cold bending and weldability are very different, and the use position of different grades of reinforcement bar is also very different. Yield strength of grade I steel is 235 MPa, ultimate strength 310 MPa, yield strength 335 MPa of grade II steel, ultimate strength 510 MPa, yield strength 400 MPa of grade III steel and ultimate strength 600 MPa. So the reinforcing bars used in the reinforcing bar net are CRB550 cold-rolled grade three steel. Now most of the welded steel mesh is used for bridge deck laying. Everyone knows that in recent years, the frequent occurrence of bridge deck collapse accidents has caused inestimable property losses. So the steel mesh used for bridge deck is also very important. Some small workshop factories have unqualified quality to steal beams and replace columns to install steel mesh with certain safety risks. The steel mesh is designed according to the national standard, so the quality of the steel mesh must be strictly produced according to the specifications and sizes designed by the national standard.
