Description

Technology Field

[0001] The present invention relates to a pallet rack and a bracket for connecting the load beam thereof, and more specifically, to a pallet rack and a bracket for connecting the load beam thereof, wherein the load beam is firmly connected to a vertical post. Background Technology

[0002] The following description merely provides background information related to the present invention and does not constitute prior art.

[0003] Generally, logistics warehouses (or logistics storage warehouses) are used as storage facilities for temporarily or for long-term storage of all daily goods, such as various foodstuffs, beverages, clothing, home appliances, miscellaneous goods, and industrial supplies, which are mass-produced at factories or production sites.

[0004] Furthermore, due to the recent rapid development of the logistics industry, these logistics warehouses are moving beyond simple logistics management to foster the creation of new businesses, ranging from the placement of stored inventory to efficient inbound and outbound shipments and inventory management. Consequently, they are being designed and constructed to enable the storage of large volumes of goods through the more efficient utilization of storage space, along with the faster inbound and outbound shipment of mass-produced items.

[0005] The design and operation of the above-mentioned logistics warehouse generally involves dividing racks with a width and height capable of handling pallets of a certain standard into aisle sections and mounting them vertically in multiple layers, after which pallets loaded with logistics are stored in the pallet racks via a forklift or forklift in the aisle sections of the fixed standard racks.

[0006] In addition, when shipping goods in a loaded state, the pallet loaded with goods is likewise moved to the ground or a transport vehicle using a forklift or forklift.

[0007] Here, a pallet refers to a support used to stably transport goods when carrying them with a forklift or similar equipment. Since goods may fall or be crushed and damaged when transported directly on a pallet, a pallet rack is a structure formed to allow for stacking in multiple layers by using a pallet as a support and forming protective guards on the sides.

[0008] Conventional pallet racks include a two-tier pallet rack with one side and the top open, disclosed in Public Patent Publication 10-1998-0048929, and a bracket for connecting a pallet rack load beam to a vertical beam, disclosed in Registered Patent Publication 10-0776531.

[0009] In this rack frame (100) on which the above-mentioned items are loaded, load beams (300) are mounted along vertical beams (200) at regular intervals, and the joints are fixedly connected through brackets (400). That is, it is common practice to insert the mounting protrusions (420, 440) of the bracket (400) into the mounting grooves (220, 240) formed in the vertical beams (200), then fix them together using bolts (520) and nuts (540), and then align the load beams (300) with the side of the bracket (400) and fix them together through welding.

[0010] And Figure 1 is a drawing showing the joint portion of a vertical beam (200) and a bracket (400), wherein mounting grooves (220) are formed along the upper and lower portions of the vertical beam (200) at regular intervals, and mounting protrusions (420) formed in the shape of the Korean character 'ㄱ' are mounted on the bracket (400) on the lower horizontal surface (222) of the mounting grooves (220).

[0011] However, since the above-mentioned coupling structure is fixed by only the horizontal surface (422) of the mounting projection (420) being caught on the lower horizontal surface (222) of the mounting groove (220), the load is concentrated on the mounting projection (420), making it difficult to use for a long time, and there was a problem that the mounting projection (420) was immediately damaged when used in a cold storage warehouse.

[0012] In addition, the bracket (400) and the load beam (300) are not firmly connected, so there is a problem that they may be damaged when heavy items are loaded for a long period of time. The problem to be solved

[0013] The technical problem that the present invention aims to solve is to improve upon the inconveniences of the prior art by providing a pallet rack and a bracket for connecting to a load beam, wherein the bracket is securely connected to the load beam and the vertical post to prevent damage to the bracket caused by the load of the goods during placement and storage.
