Abstract

The present disclosure discloses plastic composite board comprising an upper board, a lower board, and a fastener. The lower board supports the upper board. The upper board comprises a panel and a downward edge disposed on a periphery of the panel. The periphery of the panel sinks downward to define a horizontal step surface, and the downward edge extends downward from an outer edge of the horizontal step surface. The fastener comprises a buckle groove. An inner side of the buckle groove defines an opening, and the buckle groove surrounds side portions of the upper board and the lower board to fixedly clamp the upper board and the lower board together. An upper wall of the buckle groove abuts the horizontal step surface, and a top surface of the fastener is lower than a top surface of the upper board.

First claim

What is claimed is:

1. A plastic composite board, comprising:
an upper board,
a lower board, and
a fastener, wherein:
the lower board supports the upper board,
the upper board comprises a panel and a downward edge disposed on a periphery of the panel,
the periphery of the panel sinks downward and outward to define a first inclined surface,
a periphery of the first inclined surface extends outward to define a horizontal step surface,
the downward edge extends downward from an outer edge of the horizontal step surface,
the fastener comprises a buckle groove,
an inner side of the buckle groove defines an opening,
the buckle groove surrounds side portions of the upper board and the lower board to fixedly clamp the upper board and the lower board together,
an upper wall of the buckle groove abuts the horizontal step surface, and
a top surface of the buckle groove is lower than a top surface of the upper board.

2. The plastic composite board according to claim 1 , wherein:
the fastener is formed by bending a metal sheet,
the fastener further comprises an upper press edge, a side block edge, a lower press edge, and a vertical edge connected in series, and
the upper press edge, the side block edge, and the lower press edge are arranged to define the buckle groove.

3. The plastic composite board according to claim 2 , wherein a lower end of the vertical edge curls inward to define a curled edge.

4. The plastic composite board according to claim 1 , wherein:
the fastener is formed by bending a metal sheet, and
the fastener further comprises a bottom support frame connected to a lower end of the buckle groove.

5. The plastic composite board according to claim 4 , wherein:
the fastener further comprises an upper press edge, an outer block edge, a lower bottom edge, an inner block edge, a lower press edge, and a connection edge connected in series,
the connection edge abuts the outer block edge,
the outer block edge, the lower bottom edge, the inner block edge, and the lower press edge are arranged to define the bottom support frame,
the upper press edge abuts the horizontal step surface, and
the lower press edge abuts the lower board.

6. The plastic composite board according to claim 4 , wherein:
a side of the bottom support frame facing an inner side of the panel defines a second inclined surface extending upward and inward from a bottom of the side of the bottom support frame.

7. The plastic composite board according to claim 1 , wherein:
the fastener is an aluminum member,
the fastener further comprises a bottom support frame, a side block edge extending vertically upward from an outer end of a top surface of the bottom support frame, and an upper press edge extending horizontally inward from a top end of the side block edge,
the top surface of the bottom support frame, the side block edge, and the upper press edge are arranged to define the buckle groove,
the upper press edge abuts the horizontal step surface, and
the top surface of the bottom support frame abuts the lower board.

8. The plastic composite board according to claim 7 , wherein:
an inner side of a lower portion of the bottom support frame comprises a guide angle, and
a width of a bottom surface of the bottom support frame is smaller than a width of the horizontal step surface.

9. The plastic composite board according to claim 8 , wherein an inner end of the top surface of the bottom support frame extends horizontally inward to define a support board.

10. The plastic composite board according to claim 1 , wherein:
a periphery of the lower board comprises a reinforcing edge horizontally disposed, and
the reinforcing edge supports a lower end of the horizontal step surface.

11. The plastic composite board according to claim 1 , wherein:
the lower board comprises a honeycomb-shaped board and an upward edge connected to a periphery of the honeycomb-shaped board, and
the upward edge abuts the downward edge.
