Construction method for solving corrosion of steel bars at bottom of frame beam
The invention relates to the field of corrosion prevention of beam bottoms, and particularly relates to a construction method for solving corrosion of steel bars at the bottom of a frame beam. The construction method comprises the steps that a decorative layer at the bottom of the frame beam is ground off; rust of the corroded steel bars at the bottom of the frame beam is removed; the surface of the bottom of the frame beam and the surfaces of the steel bars are cleaned up; the surfaces of the steel bars are coated with antirust layers; the bottom of the frame beam is coated with a first layerof carbon fiber reinforcing glue, then carbon fiber cloth is pasted on the first layer of carbon fiber reinforcing glue, the carbon fiber cloth is coated with a second layer of carbon fiber reinforcing glue, and then medium sand is evenly scattered on the second layer of carbon fiber reinforcing glue; after the second layer of carbon fiber reinforcing glue is solidified, the surface of the mediumsand is coated with a layer of cement mortar, and then an alkali-resisting fiber mesh is pressed in; and construction of the decorative layer on the ground of the frame beam is completed. According to the construction method, air is prevented from making direct contact with the steel bars, the steel bars are prevented from being corroded, the service life of the steel bars is prolonged, and the structural safety of a steel box beam is improved.
本发明涉及梁底防腐领域，尤其是一种解决框架梁底钢筋锈蚀的施工方法，将框架梁底的装饰层磨掉；将框架梁底腐蚀的钢筋的铁锈去除掉；将框架梁底表面及钢筋表面清扫干净；钢筋表面涂刷防锈层；框架梁底部涂刷第一层碳纤维加固胶，然后在第一层碳纤维加固胶上粘贴碳纤维布，在碳纤维布上涂刷第二层碳纤维加固胶，然后将中砂均匀撒在第二层碳纤维加固胶上；第二次碳纤维加固胶凝固后，在中砂表面涂抹一层水泥砂浆，然后压入耐碱纤维网隔；框架梁地面装饰层施工完成。本发明阻绝空气与钢筋直接接触，防止钢筋被腐蚀，延长了钢筋的使用寿命，增加了钢箱梁的结构的安全性。
