Description

The postframe reinforcement materials of assembly type pallet}

The present invention is related to the post frame reinforcement member of the prefabricated pallet. More specifically, the present invention is to install reinforcement members on both ends of the longitudinal base frame that supports the post frame to effectively support the post frame where the load is concentrated when the pallet is loaded in multiple stages. This relates to post-frame reinforcing members of prefabricated pallets.

As is well known, pallets are used to load and transport multiple items, and are used in a variety of ways throughout the industry.

The types of pallets are divided into plate type and box type depending on their shape.

The former, plate-type pallet, is constructed by installing brackets to secure parts on a floor frame without using side walls. This plate-type pallet is designed to be suitable for loading large parts, especially vehicles manufactured in the form of semi-finished products.

The latter, a box-type pallet, is built vertically on top of multiple floor frames and is made up of side walls that form the four sides of the pallet, making it suitable for loading small parts.

On the other hand, the box-type pallet described above has the disadvantage of exposing many problems during storage and transportation compared to the plate-type pallet because the volume of the pallet increases due to the side walls.

A representative prior art related to a box-type pallet is the Republic of Korea Intellectual Property Office Patent No. 10-1611095 (laminated connection unit of folding pallet).

The prior art includes a base frame, a vertical frame installed vertically at the outer edge of the base frame, and a horizontal frame positioned in a horizontally lying state between the vertical frames, and both ends of which are connected and fixed to the vertical frame with a connecting bracket. In the foldable pallet composed of a frame, a support frame having a length corresponding to the foldable pallet and having a cross-section formed to have a "ㄷ" shape is welded and fixed to the bottom of the base frame, and an upward support frame is attached to the bottom end of the support frame. a locking piece that is bent vertically, a fixing frame accommodated inside both ends of the support frame, and a plurality of pieces are formed on the bottom surface of the fixing frame at a predetermined distance apart from each other, and the locking pieces of the support frame are selectively fastened to the fixing frame. A connection unit is installed to connect and secure two foldable pallets stacked upwards and downwards, which are made of the same structure and consist of a fastening slot for connecting and fixing the frame to the support frame and a hole formed between the fastening slots, and the fixing unit is installed. A protrusion protruding from the upper surface of a connecting bracket provided on a foldable pallet disposed below the foldable pallet is inserted into the hole of the frame, and is configured to connect and secure two foldable pallets stacked upward and downward. .

However, when conventional folding pallets are stacked vertically in multiple stages, the load from the upper pallet is concentrated from the lower pallet to the vertical frame at the corner, and the base frame supporting the vertical frame is not provided with a separate reinforcement means, so it is not used for a long time. When loading, the base frame cannot support the load transferred to the vertical frame and is bent or deformed, causing it to lose its function as a pallet.

As shown in FIGS. 1 to 7, the prefabricated pallet 100 includes a base frame 50, a floor frame 10 placed in a grid form on the upper surface of the base frame 50, longitudinal and transverse frames 20, 30) and post frame 40 to form the exterior.

The base frame 50 is a frame constituting the bottom of the pallet 100, and is configured to have one side open so as to have an angle cross-sectional shape of "⊃", preferably a vertical plate 52, the vertical plate 52 ) upper and lower plates (54, 56) bent at right angles in the horizontal direction at the upper and lower ends of the upper and lower plates (54, 56), upper and lower bent plates (58) bent at right angles in the vertical direction again at the ends of the upper and lower plates (54, 56) 59), and an opening 51 formed between the upper and lower bent plates 58 and 59.

The reason why the base frame 50 is molded so that an opening 51 is formed on one side is to minimize the use of materials used in molding the base frame 50. However, if one side of the base frame 50 is opened, the strength becomes weak and cannot support the load transmitted to the post frame 40. Therefore, the reinforcing member 70 of the present invention is inserted into the opening 51 of the base frame 50. ) was installed separately on the inside of both ends formed to reinforce the strength of the base frame 50.

The floor frame 10 is a frame installed on the upper surface of the base frame 50 in a grid shape along the longitudinal and transverse directions at regular intervals from each other.

The longitudinal frame 20 is a frame that forms the left and right walls among the four walls of the prefabricated pallet 100.

When describing the structure of one longitudinal frame 20, the longitudinal frame 20 has a "∩" cross-sectional structure and is molded to form a space inside, and a diagonal bar 24 is formed on the upper surface of the floor frame 10. ) is a frame that is spaced a certain distance apart and installed horizontally.

The diagonal bar 24 blocks boxes loaded on the base frame 10 from escaping into the space between the longitudinal frame 20 and the floor frame 10.

The post frame 40 is a frame installed vertically on the upper surfaces of both ends of the base frame 50, which is installed on the outer floor on both sides of the pallet. And it is a frame installed at a butt area where the transverse frames 20 and 30 are butted at right angles, and supports the longitudinal frame 20 and the transverse frame 30 to prevent them from being pushed over by the boxes being loaded.

The transverse frame 30 is a frame that forms the front and rear side walls among the four walls of the prefabricated pallet 100. That is, the transverse frames 30 are manufactured in plural pieces with the same structure and are erected vertically at the front and rear surfaces of the floor frame 10, respectively, to form the front and rear side walls of the prefabricated pallet.

The post frames 40 mounted on both ends of the base frame 50 are fixed in a one-touch manner by the support member 48 and the holder member 42.

The holder member 42 is attached to the lower end of the post frame 40, and a locking piece 44 is integrally formed on one side of the holder member 42.

The support member 48 is a member welded and mounted on both ends of the base frame 50, and the holder member 42 installed on the post frame 40 is placed in the support member 48. In addition, a locking groove 46 is formed on one side of the support member 48 for hanging the locking piece 44 of the holder member 42.

The post frame 40 can be easily fixed to both ends of the base frame 50 through the holder member 42 and the support member 48 having this structure.

Meanwhile, reinforcing members 60 supporting the load transmitted to the post frame 40 are further installed inside both ends of the base frame 50 on which the post frame 40 is supported, and the reinforcing members 60 It consists of a side plate 62 and upper and lower plates 64 and 66 provided on the upper and lower sides of the side plate 62, and reinforcing ribs 70 are provided on the front and rear sides of the reinforcing member 60, respectively. .

The reinforcing rib 70 includes a side plate 72 and upper and lower plates bent at right angles in the horizontal direction, respectively, to have the same cross-sectional shape as the base frame 50. Parts 74 and 76, an upper bent portion 78 formed by bending the tip of the upper plate portion 74 at a right angle downward, and a lower bent portion formed by bending the tip of the lower plate portion 76 at a right angle upward. (80) and upper and lower guide rails (82, 84) provided on the outer surfaces of the upper and lower bent portions (78, 80).

The upper and lower bending plates 58, 60 formed on the upper and lower portions of the base frame 50 are inserted into the upper and lower guide rails 82 and 84, respectively. ) is caught on the upper and lower bent portions 78 and 80 of the reinforcing rib 70, and through this, the reinforcing member 60 is assembled to both ends of the base frame 50 and at the same time is connected to the upper and lower bent portions 78 and 80 of the reinforcement rib 70. The weak strength of the base frame 50 is strengthened.

After the reinforcing member 60 is assembled to the base frame 50, the reinforcing member 60 and the base frame 50 are welded and fixed to each other to prevent movement.

In addition, the upper plate 64 of the reinforcing member 60 is welded to the support member 48, which is a means used to fix the above-described post frame 40 to the base frame 50, while the support member 48 is raised. The post frame 40 is fixed to the member 48 with a holder member 42.

That is, the post frame 40 is fixed to the welded support member while placed on the base frame 50 and the upper plate 64 of the reinforcing member 60, so that when the pallet is stacked in multiple stages, the pallet is connected to the post frame 40. Even if the load of (100) is transmitted, the base frame 50 and the reinforcing member 60 are supported together, preventing problems such as bending or deformation of the base frame 50 without being able to withstand the load as in the past. You can.

To assemble the reinforcing member 60, the base frame 50, and the post frame 40, first, the upper and lower bent plates 58 and 60 formed on the inside of both ends of the base frame 50 are connected to the reinforcing member 60. The upper and lower bent plates (58, 60) are inserted into the upper and lower guide rails (82, 84) formed on the reinforcing rib (70) and are hung on the upper and lower bent portions (78, 80) of the reinforcing rib (70). The reinforcing member 60 is introduced into the inside of the base frame 50 so that it holds, and then, when it reaches the appropriate position, the reinforcing member 60 is welded to the base frame 50 and fixed.

Next, the holder member 42 is welded to the lower end of the post frame 40 and the support member 48 is placed on the upper plate 64 of the reinforcing member 60, and then the holder member ( 42) is placed on the support member 48, and then the locking piece 44 of the holder member 42 is fastened to the locking groove 46 of the support member 48 to form the post frame 40 and the base frame 50. ) And the assembly of the reinforcing member 60 is completed.

In other words, when multiple pallets assembled as above are stacked vertically in multiple stages, the base frame 50 and the reinforcing member 60 together support the load transmitted to the post frame 40, thereby preventing the base frame 50 from bending. and can effectively support the pallet without deformation. In particular, even if the shape of the base frame 50 is molded so that an opening 51 is formed on the inside of the base frame 50 in consideration of cost reduction, etc., the weakness in durability is compensated through the reinforcing member 60 to form a post. The frame can be supported without bending or deformation.
