Reinforcing method for welded hollow sphere joints of grid structure
The invention relates to the technical field of constructional engineering, and discloses a grid structure welding hollow sphere joint reinforcing method which comprises the steps that 1, a grid structure welding hollow sphere joint needing to be reinforced is determined; 2, the position, needing to be pasted, of a node area is polished to be smooth, the node area is a node part composed of a welding hollow ball and a steel pipe with the length of 1.5 d, and d is the diameter of the steel pipe; step 3, preparing a strip cloth block of the carbon fiber reinforced composite material; step 4, leveling a connection welding seam of the node domain; and step 5, pasting the strip cloth block to the node domain position. According to the reinforcing method of the grid structure welded hollow sphere joint, the carbon fiber material is applied to reinforcing of the curved surface welded hollow sphere joint for the first time, the characteristics of light weight, high strength, corrosion resistance and fatigue resistance of the carbon fiber material can be fully played, and the bearing capacity and fatigue performance of the grid structure welded hollow sphere joint are greatly improved; and meanwhile, the corrosion prevention problem of the welded hollow sphere joint is solved.
本发明涉及建筑工程技术领域，公开了一种网架结构焊接空心球节点的加固方法，包括：步骤1、步骤1、确定网架结构需要加固的焊接空心球节点；步骤2、将节点域需要粘贴部位打磨光滑，节点域为焊接空心球与长度为1.5d的钢管组成的节点部分，其中，d为钢管的直径；步骤3、制备碳纤维增强复合材料的条带布块；步骤4、将节点域的连接焊缝找平；步骤5、将条带布块粘贴于节点域位置。本发明提供的一种网架结构焊接空心球节点的加固方法首次将碳纤维材料应用于曲面的焊接空心球节点加固，可以充分发挥碳纤维材料轻质、高强、耐腐蚀、抗疲劳的特点，大幅度提升网架结构焊接空心球节点的承载力和疲劳性能，同时还解决了焊接空心球节点的防腐问题。
