1. Improving the quality of reinforcing steel works remarkably:

　　與傳統(tǒng)手工綁扎鋼筋相比，焊接網(wǎng)具有網(wǎng)片鋼度度大、彈性好、間距均勻，

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

　　澆筑混凝土?xí)r鋼筋不易被局部踏彎，混凝土保護(hù)層厚度易于控制、均勻，在橋面鋪裝中，實(shí)測(cè)焊接網(wǎng)保護(hù)層的合格率在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、明顯提高施工速度：

　　2. Improving the construction speed obviously:

　　國(guó)內(nèi)外大量施工實(shí)踐表明，采用焊接網(wǎng)大量降低了現(xiàn)場(chǎng)安裝工時(shí)，省去了鋼筋加工場(chǎng)地。在鋼筋用量相同的情況下，1000kg焊接網(wǎng)如按單層鋪放約需4工時(shí)，如采用雙層網(wǎng)需6個(gè)多工時(shí)，二手工綁扎需22工時(shí)，與人工綁扎時(shí)間相比大約可節(jié)約人工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、增強(qiáng)混凝土抗裂性能：

　　3. Strengthening the crack resistance of concrete:

　　人工用鋼絲綁扎的交叉點(diǎn)易于滑動(dòng)，鋼筋與混凝土握裹力較弱，易產(chǎn)生裂縫，而焊接網(wǎng)焊點(diǎn)不僅能承受壓力，還能承受剪力?？v橫向鋼筋形成網(wǎng)狀結(jié)構(gòu)共同起粘結(jié)錨固作用，當(dāng)焊接網(wǎng)鋼筋采用較小直徑，較密的間距時(shí)，由于單位面積焊接點(diǎn)的增多，更有利于增強(qiáng)混凝土的抗裂性能，能夠減少75％以上的裂縫發(fā)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、具有較好的綜合經(jīng)濟(jì)效益：

　　4. It has better comprehensive economic benefits:

　　節(jié)省時(shí)間：采用焊接網(wǎng)節(jié)省了大量現(xiàn)場(chǎng)綁扎人工和施工現(xiàn)場(chǎng)，可以做到文明施工，使鋼筋工程質(zhì)量明顯提高，由于焊接網(wǎng)在工廠提前預(yù)制，現(xiàn)場(chǎng)不需要再加工，無鋼筋廢頭，由于縮短了施工周期，從而減少了吊裝機(jī)械等費(fèi)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.

　　節(jié)省鋼材：與使用I級(jí)鋼筋相比，帶肋鋼筋網(wǎng)的設(shè)計(jì)強(qiáng)度比I級(jí)鋼筋提高了70％左右，考慮一些構(gòu)造要求后，仍可節(jié)省鋼材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%.
