Referring to FIG. 1 to FIG. 7, a floor decker according to an embodiment of the present invention includes a first metal plate 100 and a second metal plate 200, and an upper end of the first metal plate 100 is punched downward to form a plurality of first protrusions 110; the second metal plate 200 is disposed below the first metal plate 100, a lower end surface of the first protrusion 110 is attached to an upper end surface of the second metal plate 200, and the first metal plate 100 is fixedly connected to an edge of the second metal plate 200; and a lower end of the second metal plate 200 is provided with a plurality of supporting legs 300. Compared with the prior art, in the embodiment of the present invention, the upper end of the first metal plate 100 is punched downward to form the plurality of first protrusions 110, the lower end surface of each first protrusion 110 is attached to the upper end surface of the second metal plate 200, the first protrusion 110 functions as a supporting column and can fill gaps between the first metal plate 100 and the second metal plate 200 to form a honeycomb-like structure, which improves the connection strength between the first metal plate 100 and the second metal plate 200, thereby increasing the bearing capacity of the floor decker; no supporting column needs to be arranged between the first metal plate 100 and the second metal plate 200, which can not only simplify machining procedures and improve production efficiency, but also reduce the overall weight of the floor decker to facilitate carrying and use by operators; the upper end surface of the first metal plate 100 is punched downward to form the plurality of first protrusions 110, so that the upper end surface of the first metal plate 100 is a non-smooth plane, which increases a friction force between the first metal plate 100 and goods, prevents the goods from slipping under the action of an external force, and is safe to use; in addition, the floor decker can be assembled only with two thin metal plates and supporting legs 300, which is simple in structure and low in production cost; and the metal material is convenient to recycle, and thus the floor decker is environment-friendly and saves resources. Specifically, the first metal plate 100 and the second metal plate 200 are made of galvanized sheets or electrolytic sheets. The galvanized sheets and the electrolytic sheets have high strength, high ductility, corrosion resistance and nuclear radiation resistance, efficiently reflect ultraviolet rays and are easy to machine, light, recyclable, free of insects and low-carbon and environment-friendly, so using the galvanized sheets or the electrolytic sheets to make the floor decker fully meet the use requirements for the floor decker. The floor decker made of the galvanized sheets or the electrolytic sheets generates little waste after being dismantled, and the recovery rate of the floor decker made of the removed galvanized sheets or electrolytic sheets is over 80%, which meets the requirements of environmental protection efficiency. It can be understood that the same technical effect can be achieved by stamping the second metal plate 200 to form the first protrusion 110, and attaching the upper end surface of the first protrusion 110 to the lower end surface of the first metal plate 100.
Further, there are nine supporting legs 300, and the nine supporting legs 300 are uniformly arranged at the lower end of the second metal plate 200 in three rows and three columns. As such, the floor decker can be better fixed, thereby preventing the floor decker from moving or deforming during working. Certainly, four, six, twelve or another number of supporting legs 300 may be arranged based on the actual size of the floor decker. The specific number of the supporting legs 300 is not limited herein.
As shown in FIG. 1 to FIG. 7, in some embodiments of the present invention, a plurality of second protrusions 210 are formed on the second metal plate 200 by stamping, and the lower end surfaces of the first protrusions 110 are attached to the upper end surfaces of the second protrusions 210. The second metal plate 200 is punched to form the plurality of second protrusions 210, and the second protrusions 210 are aligned with and attached to the first protrusions 110 to form columns, which further improves the connection strength between the first metal plate 100 and the second metal plate 200. In addition, the first protrusions 110 and the second protrusions 210 are aligned and connected with each other, which can further a gap between the first metal plate 100 and the second metal plate 200, so that the thicknesses of the first metal plate 100 and the second metal plate 200 can be further reduced while the strength requirements are met, thereby reducing production costs and the overall weight of the floor decker according to the embodiment of the present invention. It can be understood that the number of the first protrusions 110 is equal to the number of the second protrusions 210.
As shown in FIG. 1, FIG. 2, FIG. 3 and FIG. 5, further, to prevent water from accumulating in a groove of the first metal plate 100 at the position corresponding to the first protrusion 110 when wet goods are transferred and affecting use, a first through-hole 410 for draining water penetrates between the first protrusions 110 and the second protrusions 210 in a vertical direction. By providing the first through-hole 410, the water can be quickly discharged after the floor decker is cleaned. Specifically, attaching positions between the first protrusions 110 and the second protrusions 210 are fixed through spot welding to further improve the fastening performance of connection between the first protrusions 110 and the second protrusions 210.
As shown in FIG. 5, in some embodiments of the present invention, circular grooves 430 are formed in the first metal plate 100 at positions corresponding to the first protrusions 110 and in the second metal plate 200 at positions corresponding to the second protrusions 210. As such, the first protrusions 110 and the second protrusions 210 are formed on first metal plate 100 and the second metal plate 200 by stamping, thereby facilitating production. The first protrusions 110 and the second protrusions 210 are set into a circular shape, so that the contact area between the lower end surfaces of the first protrusions 110 and the upper end surfaces of the second protrusions 210 can be increased, and the supporting effect is more ideal. Certainly, according to the actual needs, the positions of the first metal plate 100 corresponding to the first protrusions 110 and the positions of the second metal plate 200 corresponding to the second protrusions 210 are set into grooves that are square or in other shapes, so that the first protrusions 110 and the second protrusions 210 can also be formed by stamping, to achieve the same technical effect.
As shown in FIG. 1 to FIG. 3 and FIG. 6 to FIG. 9, in some embodiments of the present invention, the supporting leg 300 is a hollow conical supporting leg, and one end of the conical supporting leg connected to the second metal plate 200 is a large-diameter end. The first metal plate 100 and the second metal plate 200 are both provided with third through-holes 420 communicated with an inner cavity of the supporting leg 300. As such, during transportation, the supporting leg 300 of one floor decker can pass through the third through-hole 420 and is placed in the inner cavity of the supporting leg 300 of another floor decker, so that a plurality of floor deckers are stacked together, which reduces the occupied area of the plurality of floor deckers according to the embodiment of the present invention during packing and transportation and reduces transportation costs. In addition, when the floor deckers are idle, they can be stacked together, which reduces the occupied area and saves storage space. Specifically, to prevent water from accumulating in the hollow supporting leg 300, the second through-hole 310 passes through the lower end surface of the supporting leg 300.
As shown in FIG. 7, FIG. 10 and FIG. 11, further, a second boss 180 is disposed at the lower end of the first metal plate 100 at the position corresponding to the supporting leg 300, a lower end surface of the second boss 180 is attached to the upper end surface of the second metal plate 200, and the third through-hole 420 passes through the second boss 180. As such, the hollow second boss 180 has the same function as the first protrusions 110 and the second protrusions 210, and functions to fill the gap between the first metal plate 100 and the second metal plate 200, thereby enhancing the strength of the positions of the floor decker where the supporting legs 300 are arranged.
In another embodiment of the present invention, the second metal plate 200 is punched to form a plurality of second protrusions 210, the first protrusions 110 are hollow first bosses, and fifth through-holes for embedding the first bosses are formed in the second protrusions 210. As such, when the first metal plate 100 and the second metal plate 200 are assembled, the first protrusions 110 are embedded in the fifth through-holes correspondingly embedded in the corresponding second protrusions 210, the upper end surfaces of the second protrusions 210 are attached to the lower end surface of the first metal plate 100. This can prevent the first metal plate 100 from moving relative to the second metal plate 200 in the process of fixedly connecting the first metal plate 100 to the edge of the second metal plate 200, to assemble the first metal plate 100 and the second metal plate 200 into a whole.

As such, the tail end of the first hook edge 130 always abuts against a side wall of the U-shaped groove 230, so that the first metal plate 100 is fixedly connected to the edge of the second metal plate 200. This prevents the situation that during use of the floor decker, the first metal plate 100 is shifted relative to the second metal plate 200, resulting in misalignment contact between the first protrusion 110 and the second protrusion 210. Therefore, the strength of the floor decker according to the embodiment of the present invention meets the use requirements.
As shown in FIG. 12 and FIG. 13, in a second embodiment of the present invention, the edge of the second metal plate 200 is folded upward to form a third vertical edge 240, and the edge of the first metal plate 100 is folded downward to form a fourth vertical edge 140 surrounding the third vertical edge 240. A lower end of the fourth vertical edge 140 is fixed to a side wall of the third vertical edge 240 through welding. The lower end of the fourth vertical edge 140 is fixed to the side wall of the third vertical edge 240 through spot welding, so that the edge of the first metal plate 100 wraps the edge of the second metal plate 200, and thus the second metal plate 200 is fixedly connected in a cavity defined by the edge of the first metal plate 100; and no displacement occurs between the first metal plate 100 and the second metal plate 200, thereby ensuring that the first protrusion 110 and the second protrusion 210 are always in alignment contact, and ensuring that the strength of the floor decker according to the embodiment of the present invention meets the use requirements.
As shown in FIG. 14 and FIG. 15, in a third embodiment of the present invention, the edge of the second metal plate 200 is folded upward to form a fifth vertical edge 250, the edge of the first metal plate 100 is folded downward to form a sixth vertical edge 150 surrounding the fifth vertical edge 250, and the length of the sixth vertical edge 150 is greater than that of the fifth vertical edge 250. A lower end of the sixth vertical edge 150 is folded inward by 90° to form a horizontal hook edge 160, and an upper end surface of the horizontal hook edge 160 is attached to the lower end surface of the second metal plate 200. As such, the first vertical edge 220 on the first metal plate 100 and the horizontal hook edge 160 wrap the edge of the first metal plate 100, so that the first metal plate 100 and the second metal plate 200 are connected to be a whole, thereby preventing the first metal plate 100 from moving relative to the second metal plate 200.
As shown in FIG. 16 and FIG. 17, in a fourth embodiment of the present invention, the edge of the second metal plate 200 is folded upward to form a seventh vertical edge 270, an upper end of the seventh vertical edge 270 is folded inward to form a second arc edge 271, a tail end of the second arc edge 271 abuts against the upper end surface of the second metal plate 200, the edge of the first metal plate 100 is folded downward to form an eighth vertical edge 190 surrounding the seventh vertical edge 270, a lower end of the eighth vertical edge 190 is folded inward to form a third arc edge 191, a tail end of the third arc edge 191 abuts against the lower end surface of the first metal plate 100, and a middle portion of the third arc edge 191 is attached to an outer side wall of the seventh vertical edge 270 and fixed through welding. The third arc edge 191 and the second arc edge 271 are folded on the first metal plate 100 and the edge of the second metal plate 200, respectively, the tail end of the third arc edge 191 abuts against the lower end surface of the first metal plate 100, and the tail end of the second arc edge 271 abuts against the upper end surface of the second metal plate 200, so that the strength of the floor decker according to the embodiment of the present invention can be further improved. The middle portion of the third arc edge 191 is attached and fixed to the outer side wall of the seventh vertical edge 270 through spot welding, so that the first metal plate 100 and the second metal plate 200 are connected to be a whole, thereby preventing the first metal plate 100 from moving relative to the second metal plate 200.
As shown in FIG. 18 and FIG. 19, in a fifth embodiment of the present invention, the edge of the first metal plate 100 is folded downward to form a first L-shaped folded edge 170, the edge of the second metal plate 200 is folded upward to form a second L-shaped folded edge 260, a lower end surface of the first L-shaped folded edge 170 is attached to an upper end surface of the second L-shaped folded edge 260, fourth through-holes pass through the first L-shaped folded edge 170 and the second L-shaped folded edge 260, and the fourth through-holes are for bolts to pass through and be matched with nuts for fixing. The first metal plate 100 is attached and fixed to the second metal plate 200 through matching between the bolts and the nuts, so that the first metal plate 100 is prevented from moving relative to the second metal plate 200, and the first protrusions 110 and the second protrusions 210 are always in alignment contact.
