抗震加固中,圈梁与横墙拉结习惯采用钢拉条(外露)或钢筋混凝土楔。这种作法的缺点是,破坏墙面较多,影响美观,在施工期间影响室内工作。 我们在攀钢钢研所主楼的抗震加固设计中,圈梁与横墙之间采用锚杆拉结。这种作法,破坏墙面较少(仅钻孔截面);因锚杆在横墙之 In the seismic strengthening, the ring beam and the transverse wall pull tie are often used steel pull bars (exposed) or reinforced concrete wedges. The disadvantage of this practice is that it destroys more walls and affects the appearance, and affects the interior work during construction. In the seismic strengthening design of the main building of the Panzhihua Iron and Steel Research Institute, we used bolts to pull the knot between the ring beam and the cross wall. This practice has less damage to the wall (only drilled sections);
