一、概况在我国钢结构工程中,高强螺栓连接技术发展很快,目前已在桥梁和工业建筑中得到广泛应用。以正在建设中的现代化大型钢铁联合企业上海宝山钢铁总厂为例,其厂房和构筑物的钢结构总量约30万吨,从码头栈桥、皮带通廊、烟囱塔架、矿槽钢架到工业厂房中的大跨度屋架、大吨位吊车梁、大型柱子和悬挂立式锅炉的电厂钢板梁等,现场安装全部采用了高强螺栓连接,高强螺栓的
I. Overview In China’s steel structure project, high-strength bolting technology has developed rapidly and is now widely used in bridges and industrial buildings. Taking the Shanghai Baoshan Iron and Steel Plant, a modern large-scale iron and steel conglomerate under construction, as an example, the total steel structure of its plants and structures is approximately 300,000 tons, ranging from pier trestles, belt corridors, chimney towers, and steel channels to industry Large-span roof trusses, large-tonnage crane girders, large-scale columns and power plant steel plate girders for hanging vertical boilers in the workshop are all installed on the site with high-strength bolts and high-strength bolts.
