合肥腳手架的發展歷程
上世紀80年(nian)代初,我國先(xian)后(hou)從國外(wai)引進(jin)門(men)式腳(jiao)(jiao)(jiao)(jiao)手(shou)(shou)架(jia)(jia)(jia)、碗(wan)扣(kou)式腳(jiao)(jiao)(jiao)(jiao)手(shou)(shou)架(jia)(jia)(jia)等(deng)多種型(xing)式腳(jiao)(jiao)(jiao)(jiao)手(shou)(shou)架(jia)(jia)(jia)。門(men)式腳(jiao)(jiao)(jiao)(jiao)手(shou)(shou)架(jia)(jia)(jia)在(zai)(zai)國內許多工程(cheng)中也曾大(da)量應用過,取(qu)得較(jiao)好的(de)效(xiao)果,由于門(men)式腳(jiao)(jiao)(jiao)(jiao)手(shou)(shou)架(jia)(jia)(jia)的(de)產品(pin)質量問題,這(zhe)種腳(jiao)(jiao)(jiao)(jiao)手(shou)(shou)架(jia)(jia)(jia)沒有(you)得到(dao)大(da)量推廣應用。在(zai)(zai)國內又建了一(yi)批門(men)式腳(jiao)(jiao)(jiao)(jiao)手(shou)(shou)架(jia)(jia)(jia)生(sheng)產廠(chang),其(qi)產品(pin)大(da)部(bu)(bu)分是按(an)外(wai)商來圖加工。碗(wan)扣(kou)式腳(jiao)(jiao)(jiao)(jiao)手(shou)(shou)架(jia)(jia)(jia)是新型(xing)腳(jiao)(jiao)(jiao)(jiao)手(shou)(shou)架(jia)(jia)(jia)中推廣應用最多的(de)一(yi)種腳(jiao)(jiao)(jiao)(jiao)手(shou)(shou)架(jia)(jia)(jia),但使用面還不廣,只有(you)部(bu)(bu)分地區和部(bu)(bu)分工程(cheng)中應用。
90年代以來,國內一些企業引進國外技術,開發了多種新型腳手架,如插銷式腳手架,CRAB模塊腳手架、圓盤式腳手(shou)(shou)架(jia)(jia)(jia)、方塔式腳手(shou)(shou)架(jia)(jia)(jia),以及各種(zhong)類型(xing)的爬架(jia)(jia)(jia)。至(zhi)2013年,國(guo)內(nei)腳手(shou)(shou)架(jia)(jia)(jia)生產(chan)企(qi)業百余家,主要在(zai)無(wu)錫、廣州、青島等地。從技(ji)術上(shang)來講,我國(guo)腳手(shou)(shou)架(jia)(jia)(jia)企(qi)業已具備加工(gong)(gong)生產(chan)各種(zhong)新型(xing)腳手(shou)(shou)架(jia)(jia)(jia)的能力。但(dan)是(shi)國(guo)內(nei)市(shi)場還沒有形成,施(shi)工(gong)(gong)企(qi)業對新型(xing)腳手(shou)(shou)架(jia)(jia)(jia)的認識還不足。
隨著我國大(da)(da)量現代化大(da)(da)型建(jian)筑(zhu)體系的出現,扣件式鋼管腳(jiao)手(shou)(shou)架已(yi)不能適應建(jian)筑(zhu)施工發(fa)展的需要,大(da)(da)力開發(fa)和推廣應用新(xin)型腳(jiao)手(shou)(shou)架是當務之急。實(shi)踐證明,采用新(xin)型腳(jiao)手(shou)(shou)架不僅施工可靠,裝拆(chai)速度快,而且腳(jiao)手(shou)(shou)架用鋼量可減少33%,裝拆(chai)工效提高兩倍以上(shang),施工成本(ben)可明顯(xian)下降,施工現場文明、整潔。
