一、前言抗震加固新加构造措施,必须使新、旧部分连接成一个整体共同进行工作,才能发挥加固的效能。因此连接节点质量的好坏非常重要。几年来,我们在工程中先后使用钢拉杆、膨胀螺栓、树脂锚杆和砂浆锚杆等多种方法。比较几种做法,砂浆锚杆效果最为显著。其优点是连接可靠、减少对住户的干扰、成本低、设备简单、容易操作,有利于提高抗震加固工程的质量和加快施工进度,所以极易推广应用。
I. INTRODUCTION With the addition of structural measures for seismic strengthening, it is imperative that the new and old parts be connected together as a whole to work together in order to achieve enhanced performance. Therefore, the quality of the connection node is very important. Over the past few years, we have used steel pull rods, expansion bolts, resin anchor rods, and mortar anchor rods and other methods in our engineering. Comparing several approaches, mortar bolts are most effective. Its advantages are reliable connection, reduced interference to tenants, low cost, simple equipment, easy operation, and it is conducive to improving the quality of anti-seismic reinforcement works and accelerating the construction progress, so it is easy to promote and apply.
