一、概述以往,在工业建筑中多采用双柱伸缩缝,即在厂房横向伸缩糙处采用双柱和双屋架。因而这些地方的柱子和屋架不能充分发挥其承重作用,造成建筑材料的浪费。我们遵照伟大领袖毛主席关于:“节省每一个铜板为着战争和革命事业,为着我们的经济建设,是我们的会计制度的原则”的教导,在工人同志的指导下,于1966年开始在某车间采用单柱伸缩缝,即在横向伸缩缝处,柱子和屋架的数量只有一个。该车间最大吊车起重量为125吨中级工作制,柱子为混凝土双肢柱和工字形柱,屋架与
I. Overview In the past, double-column expansion joints were widely used in industrial buildings, that is, double columns and double roof trusses were used in the horizontal stretching and contraction of the building. As a result, pillars and trusses in these areas are unable to fully exert their load-bearing effects, resulting in a waste of building materials. We followed the instructions of the great leader Chairman Mao on the “Save every copper plate for war and revolutionary cause, for our economic construction, is the principle of our accounting system.” Under the guidance of the workers’ comrades, we began to work in 1966. A workshop uses single-column expansion joints, that is, at the lateral expansion joints, the number of pillars and trusses is only one. The largest crane in the workshop has a lifting capacity of 125 tons. The pillars are concrete double-legs and I-shaped pillars.
