楼梯钢管扶手广泛应用于工业与民用建筑工程中,但其在平台转折处的连接处理采取热煨和冷弯圆弧工艺总有不尽人意之处。 热煨工艺:①在钢管内灌砂,砂要烘干,并且灌装密实;②均匀煨烤弯曲部位,直至钢表面呈现红黄状态;③按设计扶手坡度及梯井宽度先进行平面弯曲,再进行空间弯曲;④检查无误后自然冷却,清除管内砂子。 冷弯工艺:①应用微积分以直代曲无限分原
Staircase steel handrails are widely used in industrial and civil construction projects, but the connection process at the turning point of the platform adopts hot squat and cold-bend circular arc crafts are always unsatisfactory. Hot crucible process: 1 sand filling in the steel pipe, sand to be dry, and filling and compacting; 2 evenly crucible bending parts, until the steel surface shows a red and yellow state; 3 according to the design of handrail slope and ladder well width first plane bending, Then conduct space bending; 4 after the check is natural cooling, remove the sand inside the tube. Cold bending process: 1 Applying Calculus to Infinitely Unlimited Original
