摘　　要：分体式内膨胀墙体拉结筋连接技术是在膨胀螺栓的基础上改进产生的一种新型的锚固技术。采用分体式内膨胀螺栓进行植筋锚固,其锚固力由膨胀锚固套管与锚固基体之间的摩擦力和机械咬合力组成,与传统的注胶植筋的胶固方式相比,抗拔力大、抗振性能好、锚固质量高,在实际工程中有较好的推广应用价值。The interconnection technology of tie-bar for split type internal expansion wall is a new type of anchorage technology improved on the basis of expansion bolts. The split type internal expansion bolt has been applied to the post-embedding technology, in which the anchorage force is composed of the frictional force and the mechanical biting force between the expansion anchoring sleeve and the anchoring matrix, comparing with the traditional gluebonding anchorage mode, it has high tensile strength, good vibration resistance, excellent anchorage quality, which has won better popularization and application value in the practical engineering.
