Grouting sleeve structure and construction method

MA YUEQIANG / ZHANG YICHI / XIA YIBING

In order to simplify the construction process of a grouting sleeve, improve the construction efficiency of the grouting sleeve and reduce the human and financial cost, the invention provides a grouting sleeve structure and a construction method. The grouting sleeve structure comprises a sleeve, a sleeve sealing sleeve, a grout overflowing hole, a grout overflowing opening sealing sleeve and a structural adhesive, wherein the sleeve sealing sleeve is arranged at the bottom of the sleeve, the grout overflowing hole is formed in the top of the sleeve wall of the sleeve, the grout overflowing opening sealing sleeve is arranged at the grout overflowing opening of the grout overflowing hole, and the structural adhesive is arranged in the sleeve. According to the grouting sleeve structure, the structural adhesive is packaged in the sleeve, a to-be-connected steel bar is inserted into the sleeve from the sleeve sealing sleeve during construction, and the structural adhesive in the sleeve can react after making contact with the to-be-connected steel bar so as to generate a solidification body, so that a force transmission structure is formed, and the connection between components is completed.

为了简化灌浆套筒的施工工艺、提高灌浆套筒的施工效率、减少人力财力成本，本发明提供一种灌浆套筒结构及施工方法。本发明的一种灌浆套筒结构，包括套筒、设置于套筒底部的套筒封套、设置于套筒筒壁顶部的溢浆孔、设置于溢浆孔的溢浆口处的溢浆口封套、以及设置于套筒内的结构胶。本发明的一种灌浆套筒结构，将结构胶封装于套筒中，施工时，将待连接钢筋从套筒封套处插入套筒中，套筒内的结构胶与待连接钢筋接触后可发生反应，生成凝固体，从而形成传力结构，完成构件之间的连接。
