Description

一种H型钢组合异形柱门式刚架结构装配方法A kind of H-shaped steel combined special-shaped column portal rigid frame structure assembly method 技术领域technical field
本发明属于异形柱门式刚架结构装配技术领域,具体涉及一种H型钢组合异形柱门式刚架结构装配方法。The invention belongs to the technical field of assembling a special-shaped column portal rigid frame structure, and particularly relates to an assembly method of an H-shaped steel combined special-shaped column portal rigid frame structure.
背景技术Background technique
我国每年的单层工业厂房建设量非常大。门式刚架轻型房屋钢结构是常采用的结构体系,国家也颁布实施了《门式刚架轻型房屋钢结构技术规范》规范也规定了目前国内的门式刚架结构仅能用于起重量不大于20吨的A1~A5工作级别的桥式吊车。按照规范,门式刚架柱为等截面或变截面的H形钢柱,带桥式吊车的门式刚架结构采用等截面柱。目前应用的门式钢架结构纵向不设置与门架柱刚接的纵向钢梁,只设置支撑系统(上柱间支撑,下柱间支撑和屋面支撑)与钢系杆(牛腿处,檐口和屋脊),而门架柱为H形柱,强轴作用于钢架平面内,其绕弱轴的刚度较差,平面外稳定性依靠柱间支撑程度较高,自身的平面外稳定强度较低,上述这些原因决定了目前所使用的门式钢架结构的纵向刚度比较差,不能承受20吨以上桥式吊车带来的水平作用荷载,需要按重型厂房结构设计,结构复杂且用钢量不合理而增加结构造价。与我国倡导的发展绿色建筑和“节地、节能、节水、节材”的建筑可持续发展战略相违背。我国热轧H型钢的年产量已高达1600万吨,但热轧H型钢在钢结构中的应用仅为15%~20%,远低于发达国家40%~50%的水平,不利于国家经济建设。即使想在带20吨以下桥式吊车的门式刚架结构中使用热轧H型钢,由于其弱轴刚度差,现有生产的型钢截面不容易满足门架柱稳定承载力的要求,需要采用焊接H形截面,造价提高。国外现有热轧H型钢应用比例高的原因是采用了热轧H型钢和剖分T型钢焊成的钢异形柱替代热轧H型钢柱。但是剖分T型钢由于市场使用份额少,我国一些大型钢铁公司也是按订单来组织生产,因此剖分T型钢价格较热轧H型钢高,货源短缺,而且剖分T型钢的截面高度有限(高度仅为所选热轧H型钢的一半),因此采用钢异形柱的实际工程几乎没有。近年来,我国政府大力推广各类装配式结 构,对结构装配率也有明确要求,提高现有门式刚架的结构装配率也是必然的趋势。my country's annual construction of single-story industrial plants is very large. The steel structure of portal rigid frame light house is a commonly used structural system. The state has also promulgated and implemented the "Technical Specification for Steel Structure of Portal Rigid Frame Lightweight House", which also stipulates that the current domestic portal rigid frame structure can only be used for lifting weight. Overhead cranes of A1 to A5 working levels not greater than 20 tons. According to the specification, the portal frame column is an H-shaped steel column with constant or variable cross-section, and the portal frame structure with bridge crane adopts equal-section columns. The currently applied portal steel frame structure is not provided with longitudinal steel beams rigidly connected to the portal columns, but only with support systems (support between upper columns, support between lower columns and roof support) and steel tie rods (corbels, cornices) and roof ridge), and the gantry column is an H-shaped column, the strong axis acts in the plane of the steel frame, its stiffness around the weak axis is poor, the out-of-plane stability depends on the support degree between the columns, and its own out-of-plane stability strength is relatively high. The above reasons determine that the longitudinal rigidity of the currently used portal steel frame structure is relatively poor, and it cannot withstand the horizontal action load brought by the bridge crane of more than 20 tons. Unreasonable and increase the structural cost. It is contrary to the development of green buildings and the sustainable development strategy of "land saving, energy saving, water saving and material saving" advocated by our country. The annual output of hot-rolled H-beams in my country has reached 16 million tons, but the application of hot-rolled H-beams in steel structures is only 15% to 20%, far below the level of 40% to 50% in developed countries, which is not conducive to the national economy. building. Even if you want to use hot-rolled H-section steel in the portal frame structure with overhead cranes below 20 tons, due to the poor stiffness of the weak shaft, the existing section of the section steel is not easy to meet the requirements of the stable bearing capacity of the gantry column. Welding H-shaped section increases the cost. The reason for the high application ratio of existing hot-rolled H-beams abroad is that the hot-rolled H-beams are replaced by steel special-shaped columns welded by hot-rolled H-beams and split T-beams. However, due to the small market share of split T-section steel, some large steel companies in my country also organize production according to orders. Therefore, the price of split T-section steel is higher than that of hot-rolled H-section steel, and the supply is in short supply. Moreover, the section height of split T-section steel is limited (height). Only half of the selected hot-rolled H-beam), so there is almost no actual engineering with steel special-shaped columns. In recent years, the Chinese government has vigorously promoted various prefabricated structures, and has clear requirements for the structural assembly rate. It is also an inevitable trend to improve the structural assembly rate of the existing portal frame.
