怎样吊装柱子? | 2012-4-5 10:50:00
怎样吊装柱子?
柱子的种类很多,重量差异很大,小柱子只有2t--3t重,而大柱子则达50t--60t,在大型的重工业厂房中柱子重可达100t以上。柱子按截面形状分有钜形柱,工字形柱,管形柱和双肢柱等。钢筋混凝土柱子一般都采用在现场就位制作,重量较轻的柱子也可以在构件厂集中预制,用平板拖车运到现场再进行吊装。
一般中小型柱子的吊装腔作势,可分成两个步骤:第一步先将柱子立起来插入杯口内,对准定位轴线,作初步垂直度校正后用楔子卡紧牢固,即可摘钩;第二步是在初校的基础上再进行校正至达到要求。但重型柱、偏心较大的柱、细长术等,为保证安全,可以将柱子立起后不脱钩作校正到合乎要求后将杯口楔子打紧卡牢再摘钩。
