Description

一种箱型桥弦杆的制作方法 技术领域
本发明属于钢结构建筑技术领域，特别涉及一种箱型桥弦杆的制作方法。
背景技术
传统的桥梁大多是钢筋水泥制成，其施工周期较长，且容易受到环境的影响，影响其整个工期，而钢结构建筑，受到施工环境的影响较小，且其施工周期较短，因而近年来受到广泛的应用。
弦杆是指桁架上、下外围的杆件，上边的杆件称为上弦杆，下边的杆件称为下弦杆。无论是上弦杆还是下弦杆，其在桥梁中都不是独立设置的，大多都是需要与其他部件进行连接的，尤其是下弦杆，其不仅需要与上弦杆进行竖向连接，还需要与桥面以及端梁进行横向连接，各个部件之间的组装难度较大，现有的弦杆不具备这么多的连接节点，其在安装时，就需要采用诸多的转接件才能够实现连接，不仅增加了施工成本，同时还会增加施工的难度，延长施工的周期。
发明内容
