双壁波纹管圆柱模板施工技术

Construction Technology of Double-wall Corrugated Tube Formwork for Circular Column

深圳君临海域名园商务公寓楼圆柱施工中,采用了同圆柱直径相同的高密度聚乙烯双壁波纹管为模板,这种管材具有内壁光滑、轻质高强的特性,外壁呈环状波纹形,增加了该模板刚度,解决了施工过程中常规技术工艺遇到的实际问题。采用两个半圆进行组拼,减少模板拼缝,混凝土圆柱成型后,圆度准确,外观密实,颜色均匀;缩短了混凝土柱的施工工期,相较于普通圆柱木模板,可节省费用将近50%,创造了很好的经济效益。

In the column construction of ShenZhen JunLin-HaiYu business - apartment building, high density polyethylenedouble - wall corrugated tubes with the same diameter are usedfor formwork, which has smooth inner wall, light weight, highstrength and annular corrugated outer wall, increase the pipe rigidityand solve the practical problems met in the construction bythe routine techniques. Two semicircles are connected togetherto reduce the number of joint. This formwork made the circulardegree precise, the appearance compact, the color uniform.Compared with ordinary cylindrical wooden formwork, the corrugatedtube formwok shortened the construction period of concretecolumn, saved 5 0 % cost, created good economic benefit.
