This invention discloses a method for preparing a fully composite material rod with joints, belonging to the field of composite material connection technology. The method includes the following steps: S10, preparing a composite material rod body, pre-processing both ends of the composite material rod body with a rod body mold, removing the rod body mold after pre-processing to form the rod body component; S20, molding the composite material joint and composite material transition piece separately, then pressurizing and merging the composite material joint and composite material transition piece into a connecting joint; S30, integrally molding the connecting joint and the rod body component, and pressurizing and curing to complete the fully composite material rod product with joints. The fully composite material rod prepared by this invention has no metal parts, no fasteners, and minimizes thermal stress at high temperatures; the mold processing is simple, with no special processing required for the rod mold, connecting piece mold, and transition piece mold; the fiber continuity between the rod and the joint is good, ensuring the stress performance of the rod.

The utility model discloses an embedded part connecting structure, and relates to the technical field of embedded parts. Comprising an embedded plate and a plurality of anchor bars connected with the embedded plate. The embedded plate is detachably connected with a formwork used for concrete pouring through a plurality of bolt assemblies. An adjusting assembly is arranged between the anchor bar and the embedded plate; the adjusting assembly comprises a sliding rail and a sliding block matched with the sliding rail. The sliding rail is connected with the embedded plate, and the sliding block is connected with the anchor bar. Two sliding grooves are formed in the sliding rail, and limiting units used for limiting the sliding blocks are connected to the sliding grooves in a sliding mode.
