一、情况简介 常州印染机械试验厂为了满足工艺设备布置安装及采光要求,在国内首先采用此类结构的较大柱网(12 x 13.5m)。屋面为倒T形板轻型结构,为了减少锯齿形屋面梁构件自重,减小横梁断面,节约钢材水泥用量,提高构件抗裂度,在锯齿屋面横梁上预加应力。为使风道大梁(12m跨度方向)外表面平整及减少大梁
I. Brief Introduction Changzhou Dyeing and Printing Machinery Testing Factory adopts a large column net (12 x 13.5m) of this type of structure in order to meet the requirement of installation and lighting of the process equipment. The roof is an inverted T-shaped plate light structure, in order to reduce the self-weight of the sawtooth-shaped roof beam members, reduce the cross-section of the beam, save the amount of steel cement, increase the crack resistance of the components, and prestress on the sawtooth roof crossbeam. In order to smooth the outer surface of the air girder (in the direction of 12m span) and reduce the girder
