[0017]Referring to FIG. 1 to FIG. 7, an assembled-type door core is shown in the figures, including a hinge edge door core assembly module 1, a lock edge door core assembly module 2, and several cross beams 3 connected between the hinge edge door core assembly module 1 and the lock edge door core assembly module 2, where a first slot 4 for insertion of the cross beam 3 is arranged at a corresponding position of the hinge edge door core assembly module 1 and the lock edge door core assembly module 2, and after the cross beam 3 is inserted into the hinge edge door core assembly module 1 and the lock edge door core assembly module 2, the cross beam is assembled and fixed by a fastener. The fastener is a screw, a bolt, or a rivet. After the door core is assembled, the door core is coated with a layer of facing layer. A mounting position for mounting of a hinge is reserved on the hinge edge door core assembly module 1, and the hinge can also be directly mounted on the door core, so that ...

embodiment 2

[0024]The difference between this embodiment and embodiment 1 lies in that: in this embodiment, one end of the cross beam can further be fixed to one of the hinge edge door core assembly module 1 and the lock edge door core assembly module 2, the other end of the cross beam is a free end, and the width of the door core is adjusted by adjusting a position of the free end. When this solution is adopted, the first slot 4 at the position corresponding to the hinge edge door core assembly module 1 or the lock edge door core assembly module 2 at the fixed end of the cross beam may not be arranged.

embodiment 3

[0025]Referring to FIG. 8 and FIG. 9, the difference between this embodiment and embodiment 1 lies in that: in this embodiment, a middle cover 7 is connected to the cross beam 3. The middle cover 7 is a plate body, and may be arranged on one side or both sides of the cross beam 3 as required, so that the strength of the door core is improved. The middle cover 7 and the cross beam 3 are connected or welded by a fastener, and the fastener may also be a screw, a bolt or a rivet.
