| 摘要: |
| 为满足哈尔滨SP板厂搬迁需要,完成了该厂房的结构迁移改造．经检测鉴定,原厂房的排架柱、吊车梁、联系梁、竖向与水平支撑等结构构件可应用于新厂房．考虑到新厂房生产SP板的起吊与运输需要,通过植筋及加大截面法将排架柱接高1.8 m,加固后的排架柱直接安装在新厂房的混凝土杯口基础内．拆运的屋面梁、吊车梁及相关支撑安装就位后,在屋面梁上间隔布置了预设天窗洞口双T板与实心双T板作为屋盖,保证了厂房结构体系的安全性与经济性,有效改善了新厂房的采光通风． |

| Abstract: |
| To relocate the spancrete slab factory in Harbin, the major structural members retrofitted have been removed to a new factory. All of members including the columns, crane beam, precast beam, vertical and horizontal braces are used in new factory after detecting and identifying. The columns were increased 1.8 m by plant rebar and enlarging cross-section, and erected in new isolated footings. Other members, such as, crane beams, roof beams and braces were connected with columns. The double Tee slabs with and without rectangular holes were arranged by regular intermission on the roof beams. The safety and economy may be insured after forming the bent frames, meanwhile, the day lighting is improved. |
