某大型公建因楼层净高严格受控,大跨度、大荷载的梁截面高度受到限制,普通混凝土梁及常规的型钢组合梁难以满足设计要求,故创造性地发明采用了型钢-混凝土组合U型梁,其结构简单、施工方便、承载力强、可提高抗弯能力、减少钢材消耗量、具有经济节约性、能减小构件25%的自重、缩短工程工期等,并可与任意的钢牛腿连接而实现与次梁的顺利相接。
Due to the strict control of the floor height of a large public building, the height of the beam with large span and large load is limited. The conventional concrete beam and the conventional steel-made composite beam are difficult to meet the design requirements. Therefore, the invention adopts the steel-concrete combination type U The beam has the advantages of simple structure, convenient construction, strong bearing capacity, improved bending resistance, reduced consumption of steel, economic saving, self-weight reduction of 25% of components, shortening of project duration, etc., and can be combined with any steel cow Legs connected to achieve the smooth connection with the secondary beam.
