Description

Technical Field

[0001] The present application relates to the technical field of storage furniture, and in particular to a beam-column connection structure and a storage rack. Background Art

[0002] Shelves are used to store or organize items and are widely used in homes, offices, storage rooms, garages, and more. There are many types of shelves, including ceiling-mounted shelves, floor-standing shelves, and wall-mounted shelves. Heavy-duty shelves with high load-bearing requirements are typically floor-standing shelves placed on the ground. These shelves consist of at least two sets of vertical racks and multiple shelves distributed along the height of the racks and connected to the two sets of racks. Each set of vertical racks includes two vertical columns. Each shelf includes two parallel beams running along the length of the rack, with a shelf connected between the two beams. For example, the storage rack disclosed in patent application CN211961579U features two rows of symmetrically distributed butterfly holes on each column. The ends of the crossbeams are connected to L-shaped right-angle blocks that snap onto two adjacent surfaces of the columns. The blocks are equipped with two fixing blocks that snap onto the upper and lower butterfly holes in a row of butterfly holes, respectively. To assemble this rack, first assemble the two sets of vertical frames, then connect the two crossbeams of the shelf to the two sets of vertical frames, and finally, connect the storage board between the two crossbeams.

[0003] The above-mentioned related technical storage shelves or racks have the following defects during actual use: the fixing blocks on the right-angle blocks at both ends of the shelf beam are used to connect with the butterfly holes on the columns, which are generally stamped on the right-angle blocks. The gravity borne by the shelf is applied to the column through the fixing blocks on the right-angle blocks. If the shelf bears a heavy weight, it is easy to cause the fixing blocks on the right-angle blocks to break, causing the shelf to fall off or tilt, and its load-bearing capacity is poor and the connection stability is not high. Utility Model Content

[0004] The technical problem to be solved by the present application is to overcome the defects of the above-mentioned related technologies and provide a beam-column connection structure with strong load-bearing capacity and high connection stability.

[0005] The technical solution of the present application is to provide a beam-column connection structure with the following structure: comprising columns and beams, the columns being provided with at least two positioning holes along the height direction; the ends of the beams being connected to connecting plates, the connecting plates being provided with at least two positioning blocks along the height direction, and the two positioning blocks being respectively matched and plugged into the two positioning holes; the connecting plates and the columns being fastened together by fasteners.

[0006] In some embodiments, two positioning blocks are formed by bending on the connecting plate, and each positioning block is arranged perpendicular to the connecting plate.

[0007] In some embodiments, a connecting hole is provided on the connecting plate, and a mounting hole corresponding to the connecting hole is provided on the column; after the positioning block is plugged into the positioning hole, the connecting hole coincides with the mounting hole, and the fastener is connected in the connecting hole and the mounting hole to fasten the connecting plate to the column.

[0008] In some embodiments, the connecting plate includes adjacent first and second plates, the first and second plates are respectively adhered to the first surface and second surface adjacent to the column, the second plate is connected to the end of the beam, the positioning hole is set on the first surface, and the positioning block is set on the first plate.

[0009] In some embodiments, the mounting holes are provided on the first surface.

[0010] In some embodiments, the mounting hole is located between two adjacent positioning holes.

[0011] In summary, the beam-column connection structure of the present application has the following advantages over related technologies: The connecting plate at the end of the beam of this beam-column connection structure is positioned by inserting and positioning the positioning block into the positioning hole on the column, and then fasteners are used to fasten the connecting plate to the column. Therefore, the load-bearing capacity of the beam is shared by the inserting structure of the positioning block and the positioning hole and the fasteners, thereby enhancing the load-bearing capacity of the beam. Furthermore, the fasteners secure the connecting plate to the column, making the connection structure between the connecting plate and the column more stable and secure. Furthermore, when adjusting the height of the beam or disassembling the beam, the connecting plate can be easily removed from the column by simply removing the fasteners, making the height adjustment or disassembly of the beam very convenient and labor-saving.

[0016] Compared with the related art, the storage rack of the present application has the following advantages: the storage rack adopts the beam-column connection structure of the above-mentioned embodiment, and the load-bearing capacity of the layer assembly is jointly borne by the plug-in structure of the positioning block and the positioning hole through the beam and the fasteners, thereby enhancing the load-bearing capacity of the layer assembly; furthermore, the connecting plate of the layer assembly beam is fixed to the column by fasteners, thereby making the connection structure between the connecting plate and the column more stable and firm, and thus making the connection structure between the layer assembly and the frame more stable and firm.

[0029] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of the present application and are not intended to limit the scope of protection of the embodiments of the present application. Those skilled in the art may adjust them as needed to suit specific application scenarios.

[0030] In the description of the embodiments of this application, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of this application based on the specific circumstances.

[0031] In the embodiments of the present application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, a first feature being "above," "above," and "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0032] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] See also Figures 1 to 4As shown; the embodiment of the present application discloses a beam-column connection structure, specifically, a connection structure between a beam 200 and a column 100 used on a rack, shelf, bookshelf, etc. The beam-column connection structure includes a column 100 and a beam 200, wherein the column 100 is provided with at least two positioning holes 101 along the height direction; a connecting plate 201 is connected to the end of the beam 200, and the connecting plate 201 is provided with at least two positioning blocks 202 along the height direction. The two positioning blocks 202 are respectively matched and plugged into the two positioning holes 101 to achieve the positioning of the beam 200 on the column 100.

[0034] For example, see Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the column 100 and the beam 200 are both formed by integrally bending metal sheets. The cross section of the column 100 is rectangular and the inner side wall has an opening along the length direction. The column 100 has a first surface 107 and a second surface 108 adjacent to each other. The first surface 107 is the outer side surface of the column 100, which is parallel to the length direction of the beam 200, and the second surface 108 is perpendicular to the length direction of the beam 200; a plurality of positioning holes 101 are opened on the first surface 107 of the column 100 and along the height direction of the column 100 for adjusting the height of the beam 200. The user adjusts the height of the beam 200 according to the size of the item.

[0035] Furthermore, in this embodiment, the connecting plate 201 is fixedly connected to the end of the beam 200 by welding. Specifically, the connecting plate 201 includes adjacent first plates 208 and second plates 209, and the first plates 208 and second plates 209 are an integrally bent structure; the first plates 208 and second plates 209 are respectively fitted with the first surface 107 and the second surface 108 adjacent to the column 100, and the second plate 209 is welded and fixed to the end of the beam 200.

[0036] To facilitate the insertion of the positioning blocks 202 on the connecting plate 201 into the positioning holes 101 on the pillars 100, the positioning holes 101 are provided on the first surface 107, and the positioning blocks 202 are provided on the first plate 208. Specifically, in the above-described embodiment, two positioning blocks 202 are formed by bending on the connecting plate 201. Specifically, the two positioning blocks 202 are respectively provided at the upper and lower ends of the first plate 208, and each positioning block 202 is arranged perpendicular to the connecting plate 201. The two positioning blocks 202 are provided at the upper and lower ends of the first plate 208, so that the plate 208 can be bent directly in a bending mold, improving processing convenience.

[0037] In order to facilitate processing and reduce processing costs, in this embodiment, the positioning hole 101 is a rectangular through hole, and the positioning block 202 is configured as a plate-shaped or square-shaped positioning block 202 that matches and plugs into the positioning hole 101 .

[0038] It will be appreciated that in this embodiment, the first plate 208 and the second plate 209 of the connecting plate 201 are perpendicular to each other, and the first surface 107 and the second surface 108 of the column 100 are perpendicular to each other. When the crossbeam 200 is installed on the column 100, the first plate 208 of the connecting plate 201 is parallel to the first surface 107 of the column 100, and the connecting plate 201 is installed perpendicular to the first surface 107 of the column 100. This allows the positioning blocks 202 on the first plate 208 to be easily inserted into the positioning holes 101 on the first surface 107 of the column 100, making installation simple and convenient.

[0039] Further in this embodiment, in order to make the connection between the column 100 and the beam 200 more firm and stable, and to improve the load-bearing capacity of the beam 200; Figure 3 and Figure 4 As shown, the connecting plate 201 is fastened to the column 100 via the fastener 3. Specifically, the connecting plate 201 at the end of the crossbeam 200 is first inserted and positioned in the positioning hole 101 on the column 100 via the positioning block 202, and then the connecting plate 201 is fastened to the column 100 via the fastener 3. This allows the load-bearing capacity of the crossbeam 200 to be shared by the insertion structure of the positioning block 202 and the positioning hole 101, as well as the fastener 3, thereby enhancing the load-bearing capacity of the crossbeam 200. Furthermore, the fastener 3 secures the connecting plate 201 to the column 100, making the connection between the connecting plate 201 and the column 100 more stable and secure. To adjust the height of the crossbeam 200 or dismantle it, the connecting plate 201 can be easily removed from the column 100 by simply removing the fastener 3, making height adjustment or dismantling of the crossbeam 200 very convenient and labor-saving.

[0040] In the above embodiment, the fastener 3 is a connecting screw that fastens the connecting plate 201 and the column 100. After the connecting screw passes through the connecting plate 201 and the column 100, it is locked by a nut. Specifically, each connecting plate 201 is connected to a connecting screw to lock the connecting plate 201 on the column 100, thereby achieving a stable connection between the connecting plate 201 and the column 100. For example, see Figure 3 and Figure 4 As shown, a connecting hole 210 is provided on the connecting plate 201, and a mounting hole 102 corresponding to the connecting hole 210 is provided on the column 100; after the positioning block 202 is plugged into the positioning hole 101, the connecting hole 210 coincides with the mounting hole 102, and then the fastener 3 is connected in the connecting hole 210 and the mounting hole 102, thereby fastening the connecting plate 201 to the column 100.

[0041] In other embodiments, the fastener 3 may also be a pin tightly fitted with the mounting hole, or a bolt directly threadedly connected to the mounting hole, etc. Similarly, in other embodiments, the fastener may also be a hoop that can lock the connecting plate to the column, etc.

[0042] Furthermore, in this embodiment, the connection hole 210 is provided on the first plate member 208 of the connection plate 201, and the mounting hole 102 is provided on the first surface 107 of the column 100, with the mounting hole 102 being located between two adjacent positioning holes 101. After the positioning block 202 of the connection plate 201 is plugged into the positioning hole 101 on the column 100, the connection hole 210 on the connection plate 201 will correspond to and coincide with the positioning hole 101 on the column 100, facilitating the installation of the fastener 3. In other words, the plugging and mating of the positioning block 202 with the positioning hole 101 provides a positioning function, thereby enabling quick alignment of the connection hole 210 and the mounting hole 102.

[0043] In the above embodiment, the mounting hole 102 is located between two adjacent positioning holes 101, which may mean that the height of the mounting hole 102 is between the heights of the two adjacent positioning holes 101. Specifically, the mounting hole 102 may be located at a certain position on the connecting line of the two adjacent positioning holes 101, or may be located at a position deviated from the connecting line of the two positioning holes 101.

[0044] See also Figures 5 to 10 As shown; another embodiment of the present application discloses a storage rack, comprising a vertical frame 1 and a layer assembly 2 connected to the vertical frame 1, the vertical frame 1 comprising a column 100, the layer assembly 2 comprising a crossbeam 200, and the connection structure between the crossbeam 200 and the column 100 adopts the crossbeam-column connection structure of the above embodiment. The load-bearing capacity of the layer assembly 2 is enhanced by the crossbeam 200, which is shared by the plug-in structure of the positioning block 202 and the positioning hole 101, and the fastener 3. Furthermore, the fastener 3 is used to fix the connecting plate 201 of the crossbeam 200 of the layer assembly 2 to the column 100, thereby making the connection structure between the connecting plate 201 and the column 100 more stable and firm, thereby making the connection structure between the layer assembly 2 and the vertical frame 1 more stable and firm.

[0045] Specifically in this embodiment, see Figure 5 、 Figure 6 and Figure 7As shown, the storage rack includes at least two upright frames 1 and at least one shelf assembly 2. Each upright frame 1 includes two vertical columns 100 arranged along the width of the rack. A first tie rod 103 and a second tie rod 104, arranged along the height of the upright frame 1, are connected between the two upright frames 100. An inclined support rod 105 is connected between the first tie rod 103 and the second tie rod 104. The shelf assembly 2 is disposed between the two upright frames 1 and includes a crossbeam 200 and a storage board 203 connected to the crossbeam 200.

[0046] For example, see Figure 5 、 Figure 6 and Figure 7 As shown, the openings of the two columns 100 of each stand 1 are arranged opposite each other. A pair of connecting blocks 106 are connected to the opposing inner walls of the upper portions of the two columns 100 of each stand 1, with a first tie rod 103 connected between the connecting blocks 106. A pair of connecting blocks 106 are also connected to the opposing inner walls of the lower portions of the two columns 100, with a second tie rod 104 connected between the connecting blocks 106. A support rod 105 is arranged at an angle, with the upper end of the support rod 105 screwed to the first tie rod 103, and the lower end of the support rod 105 screwed to the second tie rod 104. The two columns 100 are connected to form a firmly connected stand 1 by the first tie rod 103, the second tie rod 104, and the support rod 105.

[0047] In order to facilitate the installation of the shelf assembly 2 and the stand 1, see Figure 9 As shown, each end of each beam 200 of the layer assembly 2 is connected to a connecting plate 201, and each connecting plate 201 is provided with two positioning blocks 202 that are respectively plugged into the two positioning holes 101 on the column 100. After the positioning blocks 202 on the connecting plates 201 at both ends of the beam 200 are respectively plugged into the positioning holes 101 on the two columns 100 on the same side of the two uprights 1, each connecting plate 201 is fastened to the column 100 by a fastener 3.

[0048] For example, see Figure 7 、 Figure 8 and Figure 9As shown, each column 100 has multiple positioning holes 101 evenly spaced along its height, with mounting holes 102 located between adjacent positioning holes 101. The shelf assembly 2 includes two crossbeams 200. The connecting plates 201 at both ends of the crossbeam 200 on the front side of the shelf are connected to the two columns 100 on the front side of the two vertical frames 1, respectively. The connecting plates 201 at both ends of the crossbeam 200 on the rear side of the shelf are connected to the two columns 100 on the rear side of the two vertical frames 1, respectively. The spacing between the two positioning blocks 202 on each connecting plate 201 is equal to the spacing between two adjacent positioning holes 101. After the positioning blocks 202 on the connecting plate 201 are inserted and positioned into the positioning holes 101 on the column 100, the fasteners 3 are passed through the connecting holes 210 on the connecting plate 201 and the mounting holes 102 on the column 100, and the connecting plate 201 is locked to the column 100 using the nuts of the fasteners 3.

[0049] In some embodiments, if there are more than two vertical racks 1, the columns 100 of each vertical rack 1 are provided with two groups of positioning holes 101 symmetrically distributed along the width direction of the columns 100, and each group of positioning holes 101 includes a plurality of positioning holes 101 evenly spaced along the height direction; this arrangement facilitates the simultaneous installation of the shelf assembly 2 on both sides of the vertical rack 1, thereby extending the length direction of the shelf. Figure 7 The rack shown is a single-section rack. If it is a double-section rack, the shelf assembly 2 needs to be installed on both sides of the middle vertical frame 1 at the same time.

[0050] It is not difficult to understand that in the relevant technology, the butterfly hole on the column is generally set as an oblique hole with a large opening at the upper end and a small opening at the lower end to facilitate the clamping of the fixing block. After the fixing block is clamped with the butterfly hole, the pressure of the weight of the goods on the shelf makes the fixing block and the lower end of the butterfly hole clamped very tightly, which makes the height adjustment and disassembly of the shelf very laborious and inconvenient to operate; in this embodiment, when adjusting the height of the shelf assembly 2 or disassembling the shelf assembly 2, it is only necessary to remove the fastener 3 to easily remove the connecting plate 201, so that the height adjustment or disassembly of the shelf assembly 2 is very convenient and labor-saving.

[0051] In other embodiments, all the positioning blocks on the connecting plate may be provided on the second plate member, and the connecting holes for the fasteners may be provided on the first plate member of the connecting plate.

[0052] The deck assembly 2 is an assembled structure, comprising at least two beams 200, each of which is provided with a plurality of pairs of sockets 207; a plurality of support rods 205 are provided between two adjacent beams 200; each support rod 205 is provided with a plug block 206 at both ends, and the two plug blocks 206 at both ends of the support rod 205 are respectively matched and plugged into a pair of sockets 207 on two adjacent beams 200. Figure 9 and Figure 10As shown, in this embodiment, each shelf assembly 2 includes two crossbeams 200 and a storage plate 203 connected to the two crossbeams 200. The storage plate 203 is a metal mesh plate, and a plurality of support rods 205 are provided between the two crossbeams 200. That is, when assembling the shelf assembly 2, the two crossbeams 200 are first clamped and positioned with the columns 100 of the two vertical frames 1, and the connecting plates 201 at the ends of the crossbeams 200 are fixed to the columns 100 using fasteners 3, ensuring that the two crossbeams 200 are at the same horizontal height. Then, the plugs 206 at both ends of the support rods 205 are respectively inserted into a pair of sockets 207 on the two crossbeams 200. After the support rods 205 are fully assembled, the metal mesh plate is covered, and the four corners of the metal mesh plate are fixedly connected to the two crossbeams 200 using screws.

[0053] It is easy to understand that the shelf assembly 2 is also a metal component and is relatively heavy. If the entire shelf assembly 2 is assembled with the stand 1, it will inevitably require the cooperation of at least two people to complete the assembly, which is a laborious process. In this embodiment, the structural arrangement of the shelf assembly 2 allows the crossbeam 200 of the shelf assembly 2 to be assembled with the stand 1 first, and then the support rods 205 and storage board 203 of the shelf assembly 2 are assembled. This makes the assembly between the shelf assembly 2 and the stand 1 more labor-saving and can be easily completed by only one person.

[0054] Furthermore, in the above embodiment, the four corners of the metal mesh are connected to mounting plates 204, which are fixed to the crossbeam 200 by screws. This arrangement makes the connection between the storage plate 203 and the crossbeam 200 more firm and stable.
