Construction method for reinforcing steel plate wall bottom I-shaped steel flange plate hole
The invention discloses a construction method for steel plate wall bottom I-shaped steel flange plate trepanning reinforcement, which comprises the following steps of: forming an arc-shaped hole in a steel plate wall bottom I-shaped steel flange plate for vertical reinforcing steel bars to penetrate through; reinforcing steel plates are additionally welded at the positions of the arc-shaped holes, and open holes which are consistent in shape and size are formed in the positions, corresponding to the arc-shaped holes, of the reinforcing steel plates. The limiting value of the stress peak value is reduced by optimizing the hole shape of the I-shaped steel flange plate at the bottom of the steel plate wall, fatigue and brittle fracture of the component are avoided, the overall bearing capacity of the flange plate is improved by additionally welding the reinforcing steel plate, the service life of the component is prolonged, meanwhile, the flange plate does not need to be replaced with a material with higher yield strength, and the cost is reduced. And the cost is saved.
本发明公开了一种钢板墙底部工字钢翼缘板开孔补强的施工方法，其包括步骤：于钢板墙底部工字钢翼缘板上开设圆弧形孔，供竖向钢筋穿设；于圆弧形孔的位置加焊补强钢板，所述补强钢板对应所述圆弧形孔的位置开设有形状和大小均一致的开孔。本发明通过对钢板墙底部工字钢翼缘板开孔形状的优化降低了应力峰值的极限值，避免了构件疲劳和脆性断裂，并通过加焊补强钢板提高翼缘板整体承载力，增加了构件的使用寿命，同时翼缘板不需要替换为屈服强度更高等级的材质，节约了成本。
