通过铁路圆端型桥墩带拉杆复合模板的受力设计实例,介绍该种模板的构造、理论计算方法及其特点。拉杆是连结内外两组模板的主要连接件,其作用是保持内外模板的间距,抵抗模板两侧的混凝土侧压力和其他荷重,确保模板有足够的刚度和强度。 Through the example of the force design of the composite model of the round-end piers of the railway piers, the structure, theoretical calculation method and characteristics of the template are introduced. The tie rod is the main connecting piece connecting the inner and outer two sets of formwork. Its function is to maintain the spacing between the inner and outer formwork and resist the concrete side pressure and other loads on both sides of the formwork to ensure that the formwork has sufficient rigidity and strength.
