某发电设备厂出口机组车间,设计为柱距12m 跨度30m 的钢筋砼排架结构,柱为长26250mm 宽2300mm 高700mm 的双肢柱,自重71000kg,见图1。由于受现有设备能力的限制,由整节柱改为二节接柱;接柱连接方式也由常规剖口焊改为新颖的钢筋冷压连接。
The outlet unit workshop of a power generation plant is designed as a reinforced concrete truss structure with a span of 12m and a span of 30m. The column is a twin limb with a length of 26250mm, a width of 2300mm and a height of 700mm. Its weight is 71000kg. See Figure 1. Due to the limitation of the existing equipment capacity, the entire section of the column was changed to two sections. The column connection mode was changed from the conventional section welding to the novel steel cold pressure connection.
