Description

Technical Field

[0001] The present invention belongs to the technical field of warehousing equipment, and particularly relates to a shelf board. Background Art

[0002] As the most common form of warehousing shelves, mezzanine shelves are widely used in industries such as manufacturing, logistics, and warehousing. As a shelf board for carrying and placing goods, it is an important component of the shelf. Currently, the shelf boards commonly used in the market are made by cutting steel plates, folding the four sides, and welding reinforcing ribs at the bottom of the steel plates.

[0003] The utility model patent with the patent number 201920516631.7 discloses a shelf board for shelves. The shelf board includes a board surface, reinforcing ribs are arranged on the board surface, a first flanging and a second flanging are respectively arranged on the opposite edges of the board surface, both the first flanging and the second flanging are folded towards the side where the reinforcing ribs are located, and the folded parts of the first flanging and the second flanging towards the board surface are completely attached to the board surface, and the first flanging and the second flanging are respectively parallel to the reinforcing ribs. The edge part of the shelf board is completely attached to the board surface as a kind of reinforcing rib, which can reduce the number of additional reinforcing ribs, save more materials, and improve the stability and load-bearing capacity of the shelf board.

[0004] The utility model patent with the patent number 202023137915.7 discloses a steel shelf board for shelves, which includes a steel plate, cross bars, and reinforcing ribs. Both sides of the steel plate are bent downward into an L shape, and cross bars are respectively arranged at both ends of the steel plate. A number of reinforcing ribs are evenly arranged between the two cross bars. The design of this steel shelf board improves the load-bearing capacity of the shelf board and enhances the anti-bending ability of the shelf board, increasing the range of the weight of goods that the shelf board can carry.

[0005] The utility model patent with the patent number 202022672101.7 discloses an adjustable shelf bearing panel. It includes: a panel, a horizontal support, a reinforcing rib, a limit, and a hexagonal bolt. Downward flangings and then inward flangings are provided at the top ends of both sides of the panel, several longitudinal reinforcing ribs are provided, the cross section of the horizontal support is a horizontal concave shape, and a concave reinforcing groove is provided in the middle of the side wall. The horizontal supports on both sides of the panel are respectively embedded inside the folded corners of the panel, and the inward flangings on the panel are embedded in the reinforcing grooves on the side walls of the horizontal supports. A number of long oval holes are provided on the bottom edge of the horizontal support, and several limits are fixed on both sides of the bottom edge of the horizontal support through the hexagonal bolts passing through the long oval holes. This bearing panel strengthens the bearing capacity, improves the structural stability, is convenient for disassembly and assembly, and has a stable structure.

[0006] It can be seen that the existing shelf boards all improve their load-bearing capacity by welding stiffeners at the bottom of the boards. During production, the shelf boards require multiple processes such as cutting and welding, and automated production cannot be achieved, resulting in relatively high processing costs. At the same time, the board body and the stiffeners belong to two separate components, and the downward gravity of the board body directly acts on the stiffeners. Under stress, the stiffeners will deform, and the stiffeners are only fixed to the board through welding points. After long-term use, metal fatigue is likely to occur at the welding points, resulting in tearing. If the shelf board is damaged, during the situation of carrying heavy objects, production accidents will occur and the carried goods will be damaged. Summary of the Invention

[0007] The purpose of the present invention is to provide a shelf board in view of the deficiencies of the prior art, wherein the board body of the shelf board is integrally formed.

[0008] The present invention includes a board body and sealing strips provided on both sides of the board body.

[0009] The said board body is integrally formed and is made by folding a metal plate, and includes a flat plate portion, flanges and stiffeners. Integral forming not only facilitates continuous processing and production, but also improves the strength of the board body.

[0010] At the positions near the edges of the two opposite sides of the metal plate, it is first folded vertically downward, and then folded inward to form flanges.

[0011] The metal plate between the two flanges is folded to form 2 - 5 stiffeners. The stiffeners are arranged parallel to the flanges, on the same side, with basically the same height. The metal plate between two adjacent stiffeners is the flat plate portion.

[0012] The overall cross-section of the said stiffener is triangular. Each stiffener includes two flipping parts and a turning part: the metal plate is first folded vertically downward to form a flipping part; then it continues to flip outward and then turns up to form a turning part; then it is folded upward and then horizontally folded to form another flipping part. The triangular cross-section design of the stiffener is more stable and improves the bearing pressure.

[0013] The two flipping parts are arranged close to each other. One flipping part has a slot, and the corresponding position of the other flipping part has a protrusion. The two flipping parts are fixed through the slot and the protrusion. After the stiffener is folded, the slot and the protrusion are pressed by a roller. The slot and the protrusion fix the two flipping parts, ensuring the stability of the board body and preventing the board body from deforming due to the separation of the two flipping parts.

[0014] The board body is continuously processed and then cut according to the required size. The cutting direction is downward along the cross-section direction of the flanges and the stiffeners from the top surface of the flat plate portion, avoiding scratching the users.

[0015] The seal described above is formed by folding a metal strip. The position of the metal strip near the long side edge is folded in the same direction to form a wide flange and a narrow flange. The wide flange is provided with a socket corresponding to the position of the reinforcing rib. The socket of the seal is aligned with the reinforcing rib and inserted inward from the end face of the reinforcing rib to wrap both ends of the reinforcing rib and at least wrap the parts of the two ends of the flange parallel to the flat part. The wide flange is fixedly connected to the bottom surface of the flat part of the shelf board body by spot welding.

[0016] Further, the reinforcing ribs are three parallel and evenly arranged ones.

[0017] The main part of the present invention - the plate body is integrally formed. The metal plate is processed by sheet metal technology into a plate body with flanges and reinforcing ribs, realizing automated processing and greatly improving production efficiency. More importantly, for the integrally formed plate body, no processes such as welding are required. The reinforcing ribs and the plate surface are integrated, and no tearing or the like will occur, making the plate body more firm. The reinforcing ribs adopt a triangular cross-section design, which can effectively improve the load-bearing pressure. The processing technology of the present invention is simple and practical and more firm. Description of the Drawings

[0022] The following further describes the present invention in conjunction with the drawings and specific embodiments.

[0023] The shelf board includes a plate body and seals arranged on both sides of the plate body.

[0024] As Figure 1 shown, the plate body 1 is formed by folding a metal plate and is integrally formed. Specifically, it includes a flat part 11, a flange 12, and a reinforcing rib 13. The positions of the two opposite sides of the metal plate near the edge are first folded vertically downward and then folded inward to form the flange 12.

[0025] The metal plate between the two flanges 12 is folded to form three evenly distributed reinforcing ribs 13. The folding method of each reinforcing rib is the same. Specifically, as Figure 2As shown: The metal plate is first folded vertically downward to form a flipped part 131; then it continues to be turned outwards and then rotated and turned upwards to form a rotating part 132; then it is folded upwards and then horizontally to form another flipped part 133. The two flipped parts 131 and 133 are closely adjacent to each other, and the cross-section of the rotating part 132 is triangular. One flipped part 131 has a card slot 134, and the corresponding position of the other flipped part 133 has a protrusion 135. The protrusion 135 is snapped into the card slot 134 to fix the two flipped parts. During the processing, after the reinforcing rib is folded and formed, the protrusion 135 and the card slot 134 are pressed by a roller. The roller is similar to a gear. One roller is provided with protruding teeth, and the other is correspondingly provided with recessed grooves. The two rollers are respectively rotated on the outside of the flipped part, and through the teeth and grooves, the embedded protrusion 135 and card slot 134 are pressed on the two flipped parts on the plane. The two flipped parts are fixed by the protrusion and the card slot, making the reinforcing rib more stable and not coming apart when bearing heavy objects. In addition, the use of a rotating part with a triangular cross-section also improves the pressure resistance of the reinforcing rib. The metal plate between two adjacent reinforcing ribs 13 is the flat plate part 11. The reinforcing ribs 13 are arranged in parallel with the flanging 12, on the same side of the flat plate part 11, and have basically the same height.

[0026] The plate body is continuously processed and then cut according to the required size. The cutting direction is from the top surface of the flat plate part to the direction of the reinforcing rib (i.e., cutting downward along the cross-section direction of the flanging and the reinforcing rib), so that the burrs generated by metal cutting are located at the edge of the bottom surface of the flat plate part and face downward; in the case of using this cutting direction, the top surface edge of the flat plate part is very smooth and will not scratch the user's hand.

[0027] As Figure 3 shown, the seal 12 is formed by folding a metal strip. The position of the metal strip near the long side edge is folded in the same direction to form a wide flanging 121 and a narrow flanging 122. The width of the wide flanging 121 is greater than the width of the narrow flanging 122. Three sockets 123 are opened at the position of the wide flanging 121 corresponding to the reinforcing rib.

[0028] As Figure 4 shown, during assembly, the socket 123 of the seal is aligned with the reinforcing rib 13 and inserted inward from the end face of the reinforcing rib to wrap the two ends of the reinforcing rib 13. The narrow flanging 122 of the seal wraps the part of the flanging ends parallel to the flat plate part. The wide flanging 121 is fixedly connected to the bottom surface of the flat plate part 11 of the plate body by spot welding, as Figure 4 the solder joints 124 in. Since the bottom surface edge of the flat plate part contacts the wide flanging 121 of the seal 2, the end of the burr generated by cutting (located at the bottom surface edge of the flat plate surface) abuts against the wide flanging 12, and at the same time, the narrow flanging 122 of the seal wraps the horizontal part of the flanging, and the downward burrs in this part are also enclosed and cannot scratch the user's hand. Therefore, after the shelf board provided by the present invention is processed, no deburring treatment is required.
