Existing building beam reinforcing method
The invention provides an existing building beam reinforcing method, and belongs to the technical field of existing building beam reinforcing. According to the existing building beam reinforcing method, the bottom of an existing building beam is supported and underpinned, and a temporary support for the existing building beam is added; a constructor determines the size and the deformation condition of the existing building beam through laser contrast construction drawings; the method comprises the following steps: estimating a load borne by a beam of the existing building; the drilling position is determined, prestressed tendons are placed after drilling, reinforced concrete is poured, and solidification of the reinforced concrete is accelerated through infrared irradiation; the cracks in the existing building beam are welded through laser beams; the method can solve the problems that an existing building beam reinforcing method cannot completely eliminate potential cracks and deformation of a beam body, so that certain potential safety hazards still exist in the using process of the beam body, and the reinforcing effect is weakened as time goes on.
本发明提供了一种既有建筑房梁加固方法，属于既有建筑房梁加固技术领域，该既有建筑房梁加固方法为在既有建筑房梁的底部支撑托换，增加对所述既有建筑房梁的临时支撑；施工人员通过激光对照施工图纸确定所述既有建筑房梁的尺寸以及变形情况；通过对所述既有建筑房梁受到的载荷进行预估；确定钻孔位置，钻孔后置入预应力筋后灌入钢筋混凝土，通过红外照射加快所述钢筋混凝土的凝固；通过激光束焊接所述既有建筑房梁内部的裂缝；该方法能够解决现有的既有建筑房梁加固方法无法完全消除梁体潜在的裂缝和变形，导致梁体在使用过程中仍然存在一定的安全隐患，随着时间的推移，加固效果会减弱的问题。
