The splicing accuracy of the precast concrete splicing component is high.

The invention discloses an LED panel light and a border thereof. The border is formed by splicing two first border section bars and two second border section bards through four angle connectors. The two second border section bars are opposite to each other. First inserting holes are formed in the first border section bards, and second inserting holes are formed in the second border section bards. The angle connectors are plate punching parts and are provided with first inserting arms and second inserting arms. The included angle formed between plane surfaces of the first inserting arms and plane surface of the second inserting arms ranges from 80 degrees to 100 degrees. The roots of the first inserting arms are connected to the roots of the second inserting arms. The heads of the first inserting arms are inserted into the first inserting holes of the first border section bards, the heads of the second inserting arms are inserted into the second inserting holes of the second border section bards, and at least three prop-up positions are arranged on the inserting arms and the inner walls of the inserting holes. The roots of the first inserting arms are bigger than the heads of the first inserting arms, so are the second inserting arms. The LED panel light is simple and reasonable in structure, convenient to assemble and debug, and high in yield and production efficiency.

The invention discloses a bolt pin-type crossed tenon tooth precast concrete unit and a preparation method thereof. The bolt pin-type crossed tenon tooth precast concrete unit comprises a first splicing part, a second splicing part, segregation boards and shearing force locking bolt pins. Tenon teeth and mortises are arranged at the splicing ends of the first splicing part and the second splicing part at intervals. Each tenon tooth is a prism with the trapezoidal cross section. The segregation boards are provided with folding structures consistent with the tenon teeth and the mortises of the second splicing part. Bolt pin holes are formed in the positions, corresponding to bolt pin mounting cavities of the second splicing part, of the segregation boards. The shearing force locking bolt pins are mounted in the first bolt pin mounting cavities and the second bolt pin mounting cavities in a penetrating mode. The bolt pin-type crossed tenon tooth precast concrete unit is simple in structure. The precision requirement for formworks is low at the prefabrication stage.
