1. Improving the quality of reinforcing steel works remarkably:

　　与传统手工绑扎钢筋相比，焊接网具有网片钢度度大、弹性好、间距均匀，

　　Compared with the traditional manual binding of steel bars, the welded mesh has the advantages of high stength, good elasticity and even spacing.

　　浇筑混凝土时钢筋不易被局部踏弯，混凝土保护层厚度易于控制、均匀，在桥面铺装中，实测焊接网保护层的合格率在95％以上。

　　When pouring concrete, the steel bar is not easy to bend locally, and the thickness of concrete protective layer is easy to control and uniform. In the bridge deck pavement, the qualified rate of welding net protective layer is more than 95%.

　　2、明显提高施工速度：

　　2. Improving the construction speed obviously:

　　国内外大量施工实践表明，采用焊接网大量降低了现场安装工时，省去了钢筋加工场地。在钢筋用量相同的情况下，1000kg焊接网如按单层铺放约需4工时，如采用双层网需6个多工时，二手工绑扎需22工时，与人工绑扎时间相比大约可节约人工50％～70％。

　　A large number of construction practices at home and abroad show that the use of welded mesh greatly reduces the site installation time and saves the steel bar processing site. With the same amount of reinforcement, it takes about 4 man-hours for 1000kg welding net to be laid by single layer, 6 man-hours for double layer net and 22 man-hours for second-hand binding, which can save about 50%-70% of man-made binding time compared with manual binding time.

　　3、增强混凝土抗裂性能：

　　3. Strengthening the crack resistance of concrete:

　　人工用钢丝绑扎的交叉点易于滑动，钢筋与混凝土握裹力较弱，易产生裂缝，而焊接网焊点不仅能承受压力，还能承受剪力。纵横向钢筋形成网状结构共同起粘结锚固作用，当焊接网钢筋采用较小直径，较密的间距时，由于单位面积焊接点的增多，更有利于增强混凝土的抗裂性能，能够减少75％以上的裂缝发生。

　　Artificial steel wire bonded intersection is easy to slip, steel bar and concrete bonding force is weak, easy to produce cracks, and welded mesh solder joint can not only withstand pressure, but also bear shear force. Longitudinal and transverse reinforcing bars form a network structure to act as bonding and anchorage. When welded reinforcing bars adopt smaller diameter and denser spacing, the increase of welded joints per unit area is more conducive to strengthening the crack resistance of concrete, which can reduce the occurrence of cracks by more than 75%.

　　4、具有较好的综合经济效益：

　　4. It has better comprehensive economic benefits:

　　节省时间：采用焊接网节省了大量现场绑扎人工和施工现场，可以做到文明施工，使钢筋工程质量明显提高，由于焊接网在工厂提前预制，现场不需要再加工，无钢筋废头，由于缩短了施工周期，从而减少了吊装机械等费用。

　　Save time: The use of welding net saves a lot of manual binding and construction site, can achieve civilized construction, so that the quality of steel engineering is significantly improved. Because welding net is prefabricated in advance in the factory, the site does not need to be reprocessed, there is no steel waste, because the construction cycle is shortened, thus reducing the cost of hoisting machinery.

　　节省钢材：与使用I级钢筋相比，带肋钢筋网的设计强度比I级钢筋提高了70％左右，考虑一些构造要求后，仍可节省钢材25％以上

　　Save steel: Compared with grade I steel bar, the design strength of ribbed steel bar net is about 70% higher than grade I steel bar. Considering some structural requirements, steel can still be saved by more than 25%.
