Description

TECHNICAL FIELD The present invention relates to an assembly type aluminum pallet, and more particularly, it is very simple and easy to assemble and disassemble, greatly improving productivity and recyclability, and firmly maintaining the assembled state. It is, of course, related to prefabricated aluminum pallets that are aesthetically pleasing.

Conventionally, a plurality of upper plates horizontally arranged at regular intervals, a first intermediate plate arranged and assembled on the lower surface of the center of the upper plate in the orthogonal direction, and arranged in the lower surface of both sides of the upper plate in the orthogonal direction. A second intermediate plate having cover pieces for protecting both lengthwise cut surfaces of the assembled upper plate, and a fork insertion part such as a forklift against the lower surfaces of the first and second intermediate plates are taken into consideration. The ratchet-shaped locking protrusions formed of the first and second intermediate plates correspond to the support wall of the upper mounting space. A square box assembled so as to be detachable from each other by a coupling means formed by ratchet-shaped locking protrusions, an underlay member including a reinforcing core detachably attached to the hollow interior of the square box, and a square of the underlay member The underlay is attached by means of a coupling means formed of ratchet-shaped locking projections formed on the support wall of the lower mounting space provided in the box and ratchet-shaped locking projections formed to correspond to the locking projections. There is a prefabricated aluminum pallet (Korea Registered Patent No. 10-0661338) which is detachably attached to the lower surface of the member and includes a lower plate which is arranged and assembled in the same direction as the first and second intermediate plates. .

However, such an assembled aluminum pallet has a minimum number of intersections between the first and second intermediate plates and the upper plate, which intersect the middle and left/right end portions of the upper plate in order to achieve the maximum weight reduction of the product. Since each rivet is fixed by one rivet, there is a problem that the rivet fixing part is easily damaged due to vibration or shock generated when cargo is loaded or moved, resulting in a shortened service life.

In addition, each assembly part must have a solid assembly structure to withstand the load of the loaded cargo as well as the shock generated during loading or moving the cargo, and the first and second intermediate plates The left and right support walls at the top of each of the underlay members are connected to the left and right support grooves at the bottom of each of the first and second intermediate plate members, and the left and right support walls at the bottom of each underlay member are connected to the left and right support grooves at the bottom of each of the lower plate members. Therefore, when cargo is loaded or moved, vibrations and impacts that are greater than the bonding force between the underlying member and the lower plate may occur, causing the first and second intermediate If it is applied to the plate or lower plate in the lengthwise (back and forth) direction, the connecting part of the underlay member and the lower plate member will slide in the length (front and back) direction, and in severe cases, There is also the problem that each assembled part is easily deformed or damaged, making it impossible to safely transport cargo.

In addition, the square column-shaped underlay member is formed by connecting the reinforcing core material so as to penetrate the hollow part of the square box having a vertical hollow part, and extending to both sides of the front wall of the reinforcing core material. The entry blocking pieces are hooked to the front ends of the left and right walls of the underlay member and are formed to extend on both sides of the rear wall of the reinforcing core member. However, due to the structure of the elastic locking piece and the hollow portion, even if the outer peripheral surface of the elastic locking piece is rounded, when the elastic locking piece passes through the hollow portion, the rear wall of the reinforcing core member makes it elastic. Since the space between the locking pieces cannot be narrowed, it is difficult to assemble the reinforcing core member so as to pass through the hollow portion of the rectangular box, which makes it impossible to implement.

In addition, by improving the mutual assembly structure between the members that make up the pallet by a detachable system, it is easy to disassemble and assemble, and it is easy to partially repair the constituent members. When it is necessary to repair the intermediate plates, the rivets, as well as the underlying member and the lower plate, must be forcibly separated, so the repair work is very difficult and takes a lot of time. However, there are also problems such as the damage caused by the damage and the difficulty of repair.

In addition, since the upper plate is fixed under the second intermediate plate provided with the cover piece, the cut sides of the upper plate in both length directions are safely protected, so that there is no risk of physical injury due to handling. Although it is said that there is an advantage that handling safety is improved by preventing it, the front and back surfaces of the cover pieces of the second intermediate plate material are exposed as they are at the four corners, so there is a risk of physical injury. However, there are also some problems such as not being able to solve all problems.
