Described precast unit interior thickness diminishes and forms plate face groove, and the two sides of plate face groove are connected with reinforcing bar, hang with reinforced steel bar ring on it; Or plate face groove has one or more transverse concave grooves on side, described transverse concave groove two sides are connected with vertical muscle, on described vertical muscle, hang with reinforced steel bar ring.During the T-section point that can be used for precast unit connects or the seam of other precast concretes.

In-line or L shaped concrete thin plates are stretched out in described precast unit side.Can be used in the L shaped node connection or floor connection of precast unit, or the seam of other precast concretes.

The present invention compared with prior art has following advantage.

(1) precast unit of the present invention hangs with reinforced steel bar ring, and reinforced steel bar ring is hinged on prefabricated units, or reinforced steel bar ring can freely adjust position within the specific limits, facilitates reinforcing bar connection between transportation, installation and the prefabricated units of precast unit etc.

(2) there is transverse concave groove precast unit of the present invention side, and vertical muscle connects the two sides of transverse concave groove, can improve the binding ability of seam crossing.In the processes such as the transportation of precast unit, installation, described reinforced steel bar ring can all or part ofly be placed in transverse concave groove, convenient construction.

(3) precast unit of the present invention can improve the industrialized level of precast concrete.Existing precast unit side reserved steel bar, job site on reserved steel bar again configuration reinforcement realize the connection between prefabricated units; Reinforced steel bar ring in the present invention can replace the reinforcing bar that in prior art, job site configures on reserved steel bar, reduces job site reinforcing bar configuration quantity, and the part reinforced bar engineering of job site is transferred to factory, improves industrialization of construction industry level.
