錨固連接支架用于軌體在錨固點位置和膨脹伸縮頭部件的安裝，要求軌體（或伸縮頭）在該安裝點截面沿X、Y、Z三個方向準確定位、牢固連接。
　　錨固連接支架上附件是帶安裝連接孔的板式結構，用于錨固點安裝時，軌體安裝槽內置一塊錨固連接內夾板，通過螺紋連接與絕緣子上附件安裝板實現安裝鎖 固，連接簡單可靠、牢固穩定。用于膨脹伸縮頭安裝時，軌體安裝槽內置的膨脹頭伸縮扣板通過螺紋連接與絕緣子上附件安裝板實現安裝鎖固。
The anchorage connection support is used for installation of the rail body in the anchorage point position and of the expansion joint components. It is required to position accurately and connect firmly the rail body (or expansion joint) in the cross section of the installation point along the directions of axes X, Y and Z.
The upper accessory of the anchorage connection support is of plate type structure with installation connection hole. In the event of use for installation in the anchorage point, an internal cleat for anchorage installation is provided in the installation slot of the rail body; installation locking is achieved by means of threaded connection and installation plate for the upper accessory of insulator; the connection is simply, reliable, firm and stable. In the event of use for installation of expansion joint, installation locking between the expansion gusset plate of expansion joint in the installation slot of the rail body and the installation plate for the upper accessory of insulator by means of threaded connection.
