根據(jù)規(guī)定,腳手架必須設(shè)置縱、橫向掃地桿??v向掃地桿應(yīng)采用直角扣件固定在距鋼管底端不大于200mm處的立桿上。橫向掃地桿應(yīng)采用直角扣件固定在緊靠縱向掃地桿下方的立桿上。腳手架是建筑施工中不可缺少的臨時設(shè)施。它是為解決在建筑物高部位施工而專門搭設(shè)的操作平臺,用于施工作業(yè)和運輸通道,臨時堆放施工材料和機具。因此,腳手架在砌筑工程、混凝土工程、裝修工程中有著廣泛的應(yīng)用。腳手架的主要作用 1)可以使操作人員在不同部位進(jìn)行施工操作; 2)按規(guī)定要求在腳手架上堆放建筑材料; 3)進(jìn)行短距離的水平運輸; 4)保證施工作業(yè)人員在高處作業(yè)時的安全。請參考下面的中英文對照:滿堂腳手架的立桿間距1.2m,橫桿間距為1.6m。每隔12m設(shè)置一道剪力撐。搭設(shè)方法見下圖。立桿與縱、橫向掃地桿連接固定,縱橫向立桿應(yīng)在同一條直線;縱、橫桿搭接接頭不要大于50%,即桿件接頭要錯位搭接。立桿搭設(shè)時應(yīng)通過吊垂線保證其垂直度,垂直誤差不得大于20mm。spacing between poles of full scaffold is 1.2m, and set cross bridging for every 12m, and method please see following sketch. poles shall be erected as per the location, and fasten the poles with longitudinal and transverse bottom pole, and longitudinal and transverse poles shall be at the same straight line. overlap junctions of longitudinal and transverse poles shall be not more than 50%, that is, pole junctions shall be overlapped staggered. verticality shall be ensured by plumb line when, and tolerance of verticality shall be not more than 20mm.
