在青岛某厂锅炉房施工中,由于厂房内装有炉体钢架及其本体,而外部施工场地有限,其上的三榀薄腹大梁吊装困难。经有关吊装单位察看,认为即使用两台40～50t级的吊车也无法将薄腹梁就位。在此情况下,我们采用了薄腹梁墙顶平移就位施工,顺利地将跨度12m的三榀薄腹梁安装就位。 1 工程概况锅炉房为该厂某新上项目的组成部分,高度20m,长29.5m,主厂房宽12m。大梁跨度12m,理论质量5.2t,连其固定架计算在内,约6t。从现场来看,较有利的吊装位置在东
In the construction of a boiler plant in a factory in Qingdao, due to the steel frame and its body in the plant, the external construction site is limited and it is difficult to lift the three-inch thin-walled girder. After reviewing the relevant lifting units, it is believed that the use of two 40-50t cranes will not be able to place thin webs in place. Under this circumstance, we adopted the construction of a thin-belly girder roof in translation and successfully installed a three-inch thin-web girder with a span of 12m. 1 Project Overview The boiler room is an integral part of a new project of the plant, with a height of 20m, a length of 29.5m, and a main plant of 12m. The span of the girder is 12m, the theoretical mass is 5.2t, and its fixed frame is included, about 6t. From the scene, the more favorable lifting position is in the east
