Description

Technical Field

[0001] This invention relates to the field of shelving technology, and more particularly to a torsion-resistant Σ-beam shelving. Background Technology

[0002] With economic progress and the rapid development of the logistics industry, large shelving units for storing goods have become widely used. To ensure the safety of stored goods, the structural stability of the shelving is a crucial consideration.

[0003] The beams of Σ-beam racks are formed by bending tubing, resulting in high strength and low material usage, thus making them widely used. For example... Figure 1 and Figure 2 As shown, the beam 200 of the Σ beam rack includes an upper flange 210 and a web 220. Goods are placed on the upper flange 210 of the beam 200. The gravitational load G generated by the goods acts on the upper flange 210 and is transmitted to the web 220. Due to the eccentricity between the point of application of the gravitational load G and the point of application of the supporting force F of the web, the beam 200 will twist. Continuing as... Figure 3 As shown, existing solutions for installing Σ-beam racks involve either installing N-shaped tie rods on the front and rear beams 200, or increasing the thickness of the beams 200. However, both methods are difficult to install, require a large amount of steel, and are costly.

[0004] Therefore, there is an urgent need to propose a torsion-resistant Σ-beam rack and its installation method to solve the above problems. Summary of the Invention

[0005] This invention provides an anti-torsion Σ-beam rack that can solve the problem of Σ-beam torsion, and uses less steel and has a lower cost.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An anti-torsion Σ-beam rack includes at least four vertically arranged uprights, at least two Σ-beams, and at least two reinforcing members. At least two of the uprights are located at the front of the anti-torsion Σ-beam rack, and at least two of the uprights are located at the rear of the anti-torsion Σ-beam rack. Each pair of Σ-beams forms a group. The two ends of one Σ-beam in the same group are vertically connected to the two uprights located at the front of the anti-torsion Σ-beam rack, and the two ends of the other Σ-beam are vertically connected to the two uprights located at the rear of the anti-torsion Σ-beam rack. Each Σ-beam includes an upper flange and a web. The upper flanges of the Σ-beams in the same group are flush. Each reinforcing member is connected to one Σ-beam. The reinforcing member and the upper flange are located on opposite sides of the web, and the top surface of the reinforcing member is flush with the top surface of the upper flange.

[0008] As an optional technical solution for anti-torsion Σ-beam racks, the reinforcing member is an L-shaped bent member, including a pressure-bearing section and a connecting section. The pressure-bearing section is flush with the upper flange, and the connecting section is fitted and connected to the web.

[0009] As an optional technical solution for anti-torsion Σ-beam racks, the reinforcing member further includes a first inner bend section, which is formed by bending the pressure-bearing section downwards.

[0010] As an optional technical solution for anti-torsion Σ-beam racks, the connecting section is connected to the web plate by multiple bolts.

[0011] As an optional technical solution for the anti-torsion Σ-beam rack, one of the bolts is located at the center position of the Σ-beam along the width direction of the anti-torsion Σ-beam rack, and the remaining bolts are symmetrically distributed along the width direction of the anti-torsion Σ-beam rack relative to the center position.

[0012] As an optional technical solution for the anti-torsion Σ-beam rack, the dimension of the reinforcing member along the width direction of the anti-torsion Σ-beam rack is smaller than the dimension of the Σ-beam along the width direction of the anti-torsion Σ-beam rack.

[0013] As an optional technical solution for the anti-torsion Σ-beam rack, the anti-torsion Σ-beam rack further includes two side support rods located on the anti-torsion Σ-beam rack, with the two ends of the side support rods being vertically connected to two uprights located at the front and rear of the anti-torsion Σ-beam rack, respectively.

[0014] As an optional technical solution for the anti-torsion Σ-beam rack, the anti-torsion Σ-beam rack also includes multiple diagonal bracing rods located on the sides of the anti-torsion Σ-beam rack, and the diagonal bracing rods are diagonally connected to two uprights located at the front and rear of the anti-torsion Σ-beam rack, respectively.

[0015] As an optional technical solution for anti-torsion Σ-beam racking, the Σ-beam is threadedly connected to the upright.

[0016] As an optional technical solution for the anti-torsion Σ beam rack, the anti-torsion Σ beam rack also includes four feet, and the uprights are inserted into the feet.

[0017] The beneficial effects of this invention are as follows:

[0018] This invention provides a torsion-resistant Σ-beam rack, comprising at least four uprights, at least two Σ-beams, and at least two reinforcing members. Each Σ-beam includes an upper flange and a web. Goods are placed on the top surface of the upper flanges of two Σ-beams in the same group. The web generates a load-bearing supporting force to support the goods. Due to the high strength of the Σ-beams, heavy goods can be stored. The reinforcing members are connected to the Σ-beams, and are located on opposite sides of the web, with the top surface of the reinforcing members flush with the top surface of the upper flanges. Half of the load is applied to the upper flanges, and half to the reinforcing members; that is, the upper flanges and reinforcing members jointly bear the load generated by the goods. The loads on the upper flanges and reinforcing members are symmetrical with respect to the web and are simultaneously transmitted to the web. In other words, the reinforcing members balance the eccentricity of load transmission in existing technologies, fundamentally solving the problem of Σ-beam torsion. Furthermore, the reinforcing members have a simple structure, use less steel, and are low in cost. Attached Figure Description

[0032] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] This embodiment provides an anti-torsion Σ-beam rack that can solve the problem of Σ-beam torsion, and uses less steel and has a lower cost.

[0034] Specifically, such as Figures 4 to 8As shown, the anti-torsion Σ-beam rack includes at least four vertically arranged uprights 100, at least two Σ-beams 200, and at least two reinforcing members 300. At least two uprights 100 are located at the front of the anti-torsion Σ-beam rack, and at least two uprights 100 are located at the rear of the anti-torsion Σ-beam rack. Each pair of Σ-beams 200 forms a group. The two ends of one Σ-beam 200 in the same group are vertically connected to the two uprights 100 located at the front of the anti-torsion Σ-beam rack, and the two ends of the other Σ-beam 200 are vertically connected to the two uprights 100 located at the rear of the anti-torsion Σ-beam rack. Goods can be placed on the two Σ-beams 200. The Σ-beam 200 includes an upper flange 210 and a web 220. The upper flanges 210 of the Σ-beams 200 in the same group are flush. The load G of the cargo acts on the upper flanges 210 of the two beams 200 and is then transferred to the web 220. The web 220 generates a supporting force F to support the cargo and bear the load G. The Σ-beam 200 has high strength and can store heavy cargo. Each reinforcing member 300 is used in conjunction with one Σ-beam 200. The reinforcing member 300 is connected to the Σ-beam 200. The reinforcing member 300 and the upper flange 210 are located on opposite sides of the web 220, and the top surface of the reinforcing member 300 is flush with the top surface of the upper flange 210. Half of the load G of the cargo is applied to the upper flange 210 and the other half to the stiffener 300. That is, the upper flange 210 and the stiffener 300 jointly bear the load G generated by the cargo. The loads on the upper flange 210 and the stiffener 300 are symmetrical with respect to the web 220 and are simultaneously transmitted to the web 220. In other words, the stiffener 300 balances the eccentricity of load transmission in existing technologies, fundamentally solving the problem of torsion of the Σ-beam 200. The stiffener 300 has a simple structure, uses less steel, and has low cost.

[0035] It should be noted that in actual application, the goods pallet is placed on the crossbeam 200, and the goods are placed on the pallet.

[0036] Further, see also Figure 6 The reinforcing member 300 is an L-shaped bent component, including a pressure-bearing section 310 and a connecting section 320. The pressure-bearing section 310 is flush with the upper flange 210, and the connecting section 320 is fitted and connected to the web 220. The L-shaped bent component can be integrally formed, which is simple to process and has a simple structure. The pressure-bearing section 310 and the upper flange 210 jointly bear the load generated by the cargo, and the connecting section 320 is used for connection with the web 220. Of course, the reinforcing member 300 can also be a separate component welded together. This application does not specifically limit the structural form and manufacturing method of the reinforcing member 300.

[0037] Furthermore, the reinforcing member 300 also includes a first inner bend section 330, which is formed by bending the pressure-bearing section 310 downwards. The edge of the pressure-bearing section 310 forms a downward bending angle, making the edge of the pressure-bearing section 310 smooth and neat, which is conducive to the stable placement of stored goods.

[0038] Similarly, the common Σ crossbeam 200 also includes a second inner bend 230, which is formed by bending the upper flange 210 downwards.

[0039] In some embodiments, the connecting segment 320 is welded to the web plate 220, and the welding connection is simple and strong. In this embodiment, the connecting segment 320 and the web plate 220 are connected by multiple bolts, making the connecting segment 320 and the web plate 220 detachably connected, which facilitates the replacement of the reinforcing member 300, and the bolt connection is simple and low in cost.

[0040] Furthermore, continue as Figure 7 and Figure 8 As shown, since the goods are usually placed in the center on the anti-torsion Σ beam shelf, the center of gravity of the resulting load is located at the center of the Σ beam 200 and the reinforcement 300 along the width direction of the anti-torsion Σ beam shelf. Therefore, placing one bolt at the center of the width direction of the anti-torsion Σ beam shelf and distributing the remaining bolts symmetrically along the width direction of the anti-torsion Σ beam shelf relative to this center position can increase the connection strength between the Σ beam 200 and the reinforcement 300.

[0041] As described above, goods are typically placed centrally on the anti-torsion Σ-beam rack. The resulting load center is located at the center of the Σ-beam 200 and the reinforcing member 300 along the width of the anti-torsion Σ-beam rack. Therefore, the reinforcing member 300 only needs to be installed in the middle along the width of the anti-torsion Σ-beam rack. Consequently, the dimension of the reinforcing member 300 along the width of the anti-torsion Σ-beam rack is smaller than the dimension of the Σ-beam 200 along the width of the anti-torsion Σ-beam rack.

[0042] Continue as Figure 7 As shown, in this embodiment, in order to increase the strength of the anti-torsion Σ beam rack, the anti-torsion Σ beam rack also includes two side support rods 400 located on the sides of the anti-torsion Σ beam rack. The two ends of the side support rods 400 are respectively vertically connected to two uprights 100 located at the front and rear of the anti-torsion Σ beam rack.

[0043] To further increase the strength of the torsional Σ-beam rack, see [link to relevant documentation]. Figure 5 The anti-torsion Σ beam rack also includes multiple diagonal braces 500 located on the sides of the anti-torsion Σ beam rack. The diagonal braces 500 are diagonally connected to two uprights 100 located at the front and rear of the anti-torsion Σ beam rack, respectively.

[0044] To increase the stability of the anti-torsion Σ beam rack, the anti-torsion Σ beam rack also includes four feet 600, with uprights 100 inserted into the feet 600.

[0045] In this embodiment, the Σ beam 200 is threadedly connected to the column 100. The detachable connection facilitates the installation and replacement of the Σ beam 200, and the connection is simple and low-cost.

[0046] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
