Assembled floor unit
The invention relates to an assembled floor unit. The bottom plate of the assembled floor unit is rectangular and comprises a frame and a middle part; the frame is provided with a clamping hook and a clamping groove, the clamping hook is suitable for cooperating with the clamping groove to enable multiple blocks of bottom plates to connect and combine; the frame and the middle part are integrally formed; a plurality of through holes penetrating the thickness direction of the bottom plate are array-distributed in the middle part. The bottom plate has the advantages of material saving, easy manufacture, light weight, and the like. The assembled floor unit with the bottom plate can eliminate the process of embedding a filling layer into the bottom plate, and the light weight but high strength is beneficial to the transportation and export sales of the product.
1. An assembled floor unit, comprising:
a bottom plate comprising a first surface and a second surface, and a decorative plate mounted on the first surface of said bottom plate;
said bottom plate comprises a frame and a middle part, the middle part having an edge;
at least one pair of opposite sides of said frame being provided with a clamping groove respectively, an opening side of said clamping groove facing the second surface;
a plurality of clamping hooks extending outwardly from said at least one pair of opposite sides respectively, a hook portion at an end of said hooks extending away from the second surface;
said clamping hooks being configured to be engaged with a corresponding clamping groove on another bottom plate to combine multiple bottom plates,
wherein said frame includes at least one reinforcing rib extending from a root of said hooks towards the edge of said middle part,
wherein said frame and said middle part are integrally injection molded and are composed of ABS engineering plastic or PS engineering plastic and respective upper surfaces thereof are at same level as the first surface;
a plurality of through holes penetrating a thickness direction of the bottom plate are array-distributed in said middle part; and
the decorative plate is adhered with glue to the upper surfaces of said frame and said middle part.
2. The assembled floor unit according to claim 1 , wherein both ends of said clamping groove are open.
3. The assembled floor unit according to claim 1 , wherein a plurality of long-circle main-holes are array-distributed in said middle part, and a first long annular rib plates extend along hole edges of the long-circle main-holes and toward the second surface of said bottom plate, ends of the first long annular rib plates are at the same level as the second surface of said bottom plate; two adjacent first long annular ribs are connected by strip ribs, and a outermost first long annular ribs are connected to said frame by strip ribs.
4. The assembled floor unit according to claim 3 , wherein a plurality of long-circle sub-holes are array-distributed in said middle part, said long-circle sub-holes and said long-circle main-holes are alternately distributed, second long annular rib plates extends along hole edges of said long-circle sub-holes towards the second surface of said bottom plate, and ends of the second long annular ribs are at the same level as the second surface of said bottom plate.
5. The assembled floor unit according to claim 1 , wherein a plurality of thickening ribs are extended outwardly from a back surface of said bottom plate along the thickness direction of said bottom plate, and distances of each thickening ribs extending outward are equal.
6. The assembled floor unit according to claim 5 , wherein a plurality of thickening columns are provided between said thickening ribs and extend outwardly along the thickness direction of said bottom plate, and the distance of said thickening columns extending outward is equal to that of said thickening ribs extending outward.
7. The assembled floor unit according to claim 1 , wherein the middle part of said bottom plate is a grid plate, and said grid plate includes evenly distributed rectangle grid holes, and a part of said grid holes are configured as said through holes.
8. The assembled floor unit according to claim 7 , wherein the first surface of said middle part is provided with at least one reinforcing strip, said reinforcing strip covering a part of the grid holes of said grid plate, a surface of said reinforcing strip is at the same level as the first surface, and said reinforcing strip is laterally or longitudinally connected to said frame, and is integrally formed with said middle part and frame.
9. The assembled floor unit according to claim 8 , wherein a thickness of said reinforcing strip is 1-1.5 mm (0.039-0.059 inch) in the thickness direction of said bottom plate.
10. The assembled floor unit according to claim 1 , wherein the at least one reinforcing rib is a plurality of reinforcing ribs, and said frame includes the reinforcing ribs extending from the root of said hooks towards the edge of said middle part.
11. The assembled floor unit according to claim 10 , wherein said reinforcing ribs are orthogonal to a wall and a bottom of said clamping grooves.
12. The assembled floor unit according to claim 11 , wherein corners of the second surface of said bottom plate are provided with reinforcing points extending from the bottom of the clamping groove to the second surface, and ends of said reinforcing points are flush with the second surface of said bottom plate or between the groove bottom and second surface of said clamping grooves.
