Fabric composite high-performance concrete reinforcing method for improving anti-seismic property of masonry wall
The invention discloses a fabric composite high-performance concrete reinforcing method for improving the anti-seismic property of a masonry wall, and belongs to the technical field of reinforcing and repairing of masonry structures. The method comprises the steps that a plurality of round holes are drilled in the surface of a masonry wall, the drilling depth is not smaller than 10 times of the diameter of an L-shaped anchor bar, dust in the holes is blown away through an air gun, then epoxy resin bar planting glue is squeezed into the holes through a glue gun, the whole holes are filled with the glue, the L-shaped anchor bar is screwed into the holes, standing is conducted for 24 hours till the epoxy resin glue is solidified, and then the holes are formed; the construction method comprises the following steps: firstly, building a constructional column, then chiseling the surface of the constructional column, wetting a to-be-reinforced wall body and the surface of the constructional column with water, arranging a first layer of high-performance concrete matrix, then paving a fiber woven mesh, finally arranging a second layer of high-performance concrete matrix, and carrying out wet water maintenance, so that the anti-seismic property of the masonry wall is effectively improved; casualties and property loss caused by earthquakes are reduced, and technical support is provided for reinforcement and reconstruction of urban old communities and historical masonry buildings.
本发明公开了一种提高砌体墙抗震性能的织物复合高性能混凝土加固方法，属砌体结构的加固修复技术领域。该方法在砌体墙表面钻取多个圆孔，钻孔深度为不小于10倍的“L”型锚筋直径，将孔洞中的灰尘用气枪吹净，然后将环氧树脂植筋胶用胶枪挤入孔洞中，务必将胶灌满整个孔洞，将“L”型锚筋旋入孔洞中并静置24小时至环氧树脂胶凝固，然后将构造柱表面进行凿毛，将待加固墙体与构造柱表面用水进行湿润处理后设置第1层高性能混凝土基体，然后铺设纤维编织网，最后设置第2层高性能混凝土基体，湿水养护，有效提高砌体墙的抗震性能，减少地震带来的人员伤亡和财产损失，为城镇老旧小区以及历史砌体建筑的加固改造提供技术支持。
