The lane body comprises a frame and a grating plate 20 disposed on the frame; the first reinforcement layer is disposed on the back of the grating plate 20; the second reinforcement layer 70 is disposed on the front of the grating plate 20, with at least a portion of the grating plate 20 embedded in the second reinforcement layer 70. The lane provided by the embodiment of the present invention can be flexibly placed in any desired location. The second reinforcement layer 70 improves the overall structural strength and does not damage forklift wheels. The grating plate 20 also serves as anti-cracking reinforcement for the second reinforcement layer 70, ensuring its durability. The first reinforcement layer ensures that the thickness of the second reinforcement layer 70 is not excessive while maintaining overall structural strength, thus avoiding deformation of the lane caused by the increased weight of the second reinforcement layer 70 and reducing costs. Therefore, the lane provided by the embodiment of the present invention combines the advantages of portability, durability, protection of forklift wheels, and low cost.

[0032] Specifically, the frame includes a plurality of frame bars 11 and a plurality of inner frame bars 12. The plurality of frame bars 11 are connected end to end to form a closed frame. The plurality of inner frame bars 12 are disposed within the closed frame and spaced apart along a first direction. The grille plate 20 is disposed within the closed frame and supported by the plurality of inner frame bars 12. In this embodiment, there are four frame bars 11, which are connected end to end to form a rectangular closed frame. The inner frame bars 12 are parallel to the length of the rectangular closed frame, and the plurality of inner frame bars 12 are spaced apart along the width direction (i.e., the first direction) of the rectangular closed frame. In this embodiment, the frame bars 11 and the inner frame bars 12 are both made of steel pipes with a rectangular cross-section; the grille plate 20 is a hot-dip galvanized component. Furthermore, the frame includes a guardrail 13. The upper ends of the two frame bars 11 extending along the length of the rectangular closed frame are each provided with a guardrail 13. The guardrail 13 is used to provide protection when a forklift is traveling on the lane.

[0033] Optionally, the first reinforcement layer includes a plurality of panels 30, which are placed between adjacent inner frame bars 12 and between the inner frame bars 12 and the border bars 11. Optionally, the panels 30 are extruded boards. The second reinforcement layer 70 is a concrete surface layer. The concrete surface layer is formed by pouring concrete on the front surface of the grid plate 20. In this embodiment, the concrete is C40 micro-expanded fine stone concrete.

[0034] The driveway further includes a formwork 50, which is mounted on the back of the frame and connected to the inner frame bars 12 of the frame via fasteners 60. The first reinforcement layer is located between the grating plate 20 and the formwork 50. The formwork 50 not only secures the first reinforcement layer but also supports the second reinforcement layer 70, ensuring the quality of the casting of the second reinforcement layer 70. In this embodiment, the formwork 50 is made of galvanized steel.

[0035] Furthermore, the lane also includes a frame 40, which is arranged around the frame, and the upper end surface of the frame 40 is higher than the front surface of the grille plate 20. The second reinforcement layer 70 is located in the space enclosed by the frame 40 and is no higher than the upper end surface of the frame 40. The frame 40 can limit the position of the second reinforcement layer 70, ensuring the casting quality of the second reinforcement layer 70.

[0036] Combine Figure 5 The manufacturing method of the lane is described in detail. The manufacturing method of the lane is used to manufacture the above-mentioned lane, and includes the following steps:

[0037] S1. Turn the lane body over so that the back is facing upward.

[0038] S2. Fill the back surface of the grid plate 20 with a plate member 30 to form a first reinforcement layer.

[0039] Specifically, the space between adjacent inner frame bars 12 and between the inner frame bars 12 and the border bars 11 is filled with plate members 30 to form a first reinforcement layer. In this embodiment, the filled plate members 30 are extruded plates with a thickness of 50 mm.

[0040] S3. Install a galvanized steel plate on the back of the frame to serve as a template 50.

[0041] Specifically, a galvanized steel sheet is placed within the closed frame formed by the frame bars 11 and supported on the back of the inner frame bars 12. Fasteners 60 (e.g., self-tapping screws) are used to securely connect the galvanized steel sheet to the inner frame bars 12. The galvanized steel sheet serves as the formwork 50, providing support during the subsequent concrete pouring to ensure the quality of the second reinforcement layer 70. In this embodiment, the thickness of the galvanized steel sheet is 1.5 mm, but this is not limiting.

[0042] S4. Turn the lane body over so that the front side faces upward.

[0043] After the lane body is turned over to face up, the lane body is supported by stirrups.

[0044] S5. Weld the surrounding frame 40 around the frame so that the upper end surface of the surrounding frame 40 is higher than the front surface of the grid plate 20.

[0045] In this embodiment, the frame 40 is made of flat iron. In this embodiment, the frame 40 has a height of 45 mm and a thickness of 3 mm, but is not limited thereto.

[0046] S6. Concrete is poured on the front surface of the grid plate 20 to form a second reinforcement layer 70 . The second reinforcement layer 70 is not higher than the upper end surface of the surrounding frame 40 .

[0047] In this embodiment, C40 micro-expanded fine stone concrete is used. It is understood that when pouring the second reinforcement layer 70, the C40 micro-expanded fine stone concrete will flow through the holes in the grid plate 20 to the back of the grid plate 20, effectively embedding the grid plate 20 into the second reinforcement layer 70. Therefore, the grid plate 20 can serve as the anti-cracking steel bar of the second reinforcement layer 70.

[0048] In this embodiment, the thickness of the second reinforcement layer 70 above the upper end surface of the grid plate 20 is 20 mm, the thickness of the grid plate 20 is 30 mm, and the thickness of the plate 30 is 50 mm, that is, the total thickness of the lane is 100 mm.

[0049] The lane is tilted when in use, supported at its lower end by multiple sets of support rods 90. These rods are spaced along the length of the lane and gradually increase in height as they approach the warehouse door, tilting the lane upward toward the warehouse door. The lane connects to the ground via a first transition plate 81, and to the warehouse door via a second transition plate 82.

[0050] Optionally, the lane provided in the embodiment of the present utility model can be used as a forklift ramp, but is not limited to this.

[0051] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
