在旧房增层改造和抗震加固中,砼构件之间、砌体之间、砌体和其它构件之间的联结处理非常重要。树脂锚杆是一种新型的粘结锚固构件,它依靠锚杆和树脂胶泥之间、树脂胶泥和构件之间的粘结力,形成粘结锚固构件。几年来,作者在旧房增层改造和抗震加固的设计和施工中,应用树脂锚杆技术,取得了显著效果。实践证明,树脂 In the addition of retrofitting and anti-seismic reinforcement of old buildings, it is very important to connect the concrete elements, masonry, masonry and other components. The resin anchor rod is a new kind of adhesive anchoring member, which depends on the adhesive force between the anchor rod and the resin clay, between the resin clay and the member, to form the adhesive anchoring member. Over the past few years, the authors have applied resin bolt technology in the design and construction of the old house building and seismic reinforcement and achieved remarkable results. Practice has proved that resin
