Repairing and reinforcing method for earthquake-damaged concrete frame structure
The invention discloses a method for repairing and reinforcing an earthquake-damaged concrete frame structure, which comprises the following steps of: removing crushed concrete in an existing concrete frame, and pouring a high-strength grouting material to repair the appearance; h-shaped steel is connected to the inner side of a column in the existing concrete frame in parallel through a plurality of anchor bolts, and one end of a screw in each anchor bolt penetrates through a flange and an end plate of the H-shaped steel to be fixed in a drill hole of the existing concrete frame; the other end of the screw rod is fixed through a nut; a gap is reserved between the H-shaped steel and the existing concrete frame, a high-strength grouting material is poured into the gap, and repairing and reinforcing are completed after forming. According to the method, the crushed concrete is removed, and then the removed part is poured with the high-strength grouting material again, so that the structure is repaired; the structure is further reinforced on the inner side of the column through the method that anchor bolts are connected in parallel with H shapes, and the anti-seismic performance is improved.
本发明公开了一种震损混凝土框架结构的修复加固方法，包括，剔除既有混凝土框架中的压溃混凝土，浇筑高强灌浆料进行外形修复；将H型钢通过多个锚栓并联在既有混凝土框架中的柱子内侧，锚栓中的螺杆的一端穿过H型钢的翼缘和端板固定在既有混凝土框架的钻孔中；螺杆的另一端通过螺帽进行固定；H型钢与既有混凝土框架之间预留空隙，在空隙处浇筑高强灌浆料，成型后完成修复加固。本发明通过剔除压溃的混凝土，然后将剔除的部分重新浇筑高强灌浆料，从而实现对结构的修复；在柱子内侧利用锚栓并联H型的方法对结构进一步加固，提升抗震性能。
