Description

Assembly type steel pallet

The present invention relates to a prefabricated metal pallet, and more particularly, to a pallet for a pallet, which is capable of stacking and transporting an upper plate and a lower plate integrally coupled with each other to support a pallet, The present invention also relates to a prefabricated steel pallet which can be easily assembled and disassembled so that it can be quickly and accurately assembled and used in the field, as well as minimizing the weight of the pallet formed by joining the steel frames and enhancing the supporting force.

Generally, a pallet disposed at the lower part of a bundle bundle for facilitating the transportation of forklifts is made of wood, synthetic resin, etc., and has been widely used for transportation of cargoes at most factories or quays.

However, the conventional pallet described above has a problem in that the volume of the empty pallet itself except for the cargo is formed to be too large, which makes the volume of the cargo unnecessarily unnecessarily large, resulting in an excessive cost of logistics.

In addition, the pallet of wood material can be produced various kinds of germs, which is unsafe for hygiene, and a pallet made of plastic or synthetic resin that can replace it is advantageous in that the production cost is low. However, So that it is practically impossible to produce pallets of various sizes.

In recent years, in order to compensate for this problem, conventional steel pallets have been produced, but the number of parts has increased, resulting in problems such as an increase in production costs and difficulty in automating mass production, and the assembled piece bolts are easily relaxed due to vibration during prolonged use And the shortage of the service life of the pallet has shortened. After that, the entire pallet has been integrally manufactured up to the leg portion. However, various difficulties such as the excessive installation of the equipment cost are appearing. In order to achieve the purpose of the pallet, And so on.

In addition, conventionally, since the middle plate for joining the upper plate and the lower plate is manufactured by welding, even when the pallet is not used, it must be transported and stored in the assembled state. Therefore, the pallet is heavy and bulky, So that it is not easy to handle.

As a technique for solving such a problem, Korean Patent Registration No. 10-1222932 discloses a prefabricated pallet, which is a registered patent of the present applicant, and its main technical structure is a prefabricated pallet comprising a top plate, Wherein the intermediate support is slidably fitted between the upper plate and the lower plate.

That is, the above-mentioned prior art is characterized in that the middle plate is fitted between the upper plate and the lower plate by a sliding method so that the upper plate and the lower plate constituting the pallet can be easily assembled by a simple structure. However, Even if pallets are made of a single piece of steel plate, the pallets may be deformed when the heavy cargo is continuously transported, and the rim of the pallet may be sharpened, .

In addition, the conventional steel pallet has been made into a roll structure by applying a lot of curvature to the plate-shaped plate in order to strengthen the supporting force while being made to have a light structure. However, There is a problem that the outer portion of the pallet becomes very vulnerable to damage.

More specifically, the upper plate 100 supports a load placed on the upper portion. The upper plate 100 includes a first outer frame 110 having a 'ㅁ' shape and a second outer frame 110 ' And a plurality of first and second vertical frames 120 and 130 installed in the longitudinal direction inside the first and second vertical frames 110 and 110.

That is, the rim of the upper plate 100 is formed by using the first outer frame 110, and the rim of the first outer frame 110 is formed on the inner side of the first outer frame 110 by a predetermined distance, The first vertical frame 120 and the second vertical frame 130 are provided in the vertical direction by a welding method such as welding so as to be able to support the load placed on the upper portion, (200) can be integrally coupled between the first and second vertical frames (120, 130).

As shown in FIG. 2, the first outer frame 110 and the first and second vertical frames 120 and 130 may be formed such that their longitudinal sides have a cross-section of a ' The first and second vertical frames 120 and 130 are formed such that the opened side faces in opposite directions, that is, the closed side is the same as the first side, And a leg member 200 to be described later is installed between the closed side faces of the first and second vertical frames 120 and 130 so as to be integrally installed by a joining method such as spot welding.

In addition, the first outer frame 110 is formed by rounding four corners so as to prevent the occurrence of injury or damage to the load due to the sharpness of the corner portions.

In addition, the first outer frame 110 and the first and second vertical frames 120 and 130 formed to have a 'C' -shaped cross-section prevent deformation due to loads or shocks from the external load The thickness of the closed side provided in the vertical direction may be thicker than the side provided in the horizontal direction so that the both side ends and the outer edge portions are rounded by the side rolling method, And can be configured so as to prevent an operator from being injured.

Meanwhile, the first and second vertical frames 120 and 130 may have a double structure in order to improve the structural strength of the first and second vertical frames 120 and 130 and to prevent deformation of the load due to the load, In this case, the first and second vertical frames 120 and 130 are manufactured by bending one plate.

More specifically, as shown in FIGS. 7A and 7B, one plate is folded to form upper and lower surfaces of the first and second vertical frames 120 and 130 ' And both ends of the plate are bent so as to be engaged with each other and are bent so as to be engaged with each other at the closed side portions of the first and second vertical frames 120 and 130 so that the first reinforcing portions 124 and 134 made of a five- As shown in FIG.

The leg member 200 is vertically connected between the upper plate 100 and the lower plate 300 to support the upper plate 100. The upper and lower legs 200 are formed in a shape U 'shape so that the upper end thereof is integrally coupled between the first and second vertical frames 120 and 130 of the upper plate 100.

That is, the leg member 200 is integrally joined between the first and second vertical frames 120 and 130 by the joining method such as welding or the like by fastening using bolts or rivets, The upper part 100 having the upper part opened is transported to the worksite for the purpose of export or the like, as shown in FIG. 14, the upper part 100, to which the leg parts 200 are integrally connected, So that it is possible to reduce the volume and to reduce the cost of logistics accordingly.

In addition, the leg member 200 is formed in a shape of upper light lowering so that the volume of the upper plate 100, to which the leg members 200 are integrally coupled, can be minimized, Both sides are opened so that the lamination can be more easily performed and the weight can be reduced.

4 (a), a bent portion 210 is formed at the upper end of the leg member 200 to bend outward. Both ends of the bent portion 210 are bent upward This increases the contact area between the leg member 200 and the first and second vertical frames 120 and 130 so that the leg member 200 is more tightly coupled between the first and second vertical frames 120 and 130 .

In addition, one or more first forceps 220 are formed on both sides of the leg member 200, that is, on both sides in the longitudinal direction, so that the load bearing capacity, i.e., the structural strength, of the leg member 200 can be improved So that the shape of the leg member 200 can be prevented from being deformed by a load of the load or an impact from the outside.

An engaging groove 230 is formed on the lower both sides of the leg member 200. The engaging member 320 of the lower plate 300 to be described later is engaged with the engaging groove 230. [

5 (a) and 5 (b), a leg member 200 is formed to have a U-shaped shape with both upper and lower sides opened, The folded portion 210 may be formed in two or more folds outwardly bent at the upper end of the leg portion 200 to improve the supporting force of the leg member 200.

That is, the outer end of the bent portion 210 is bent downward or upward so that the end portion is directed inward, so that the reinforcing portion 250 having two layers can be formed at the upper end of the leg member 200, It is possible to improve the supporting force of the leg member 200 and to prevent the deformation of the bent portion 210 due to the load applied to the leg member 200. [

In this case, although not shown, it is needless to say that the bending process for forming the reinforcing portion 250 may be repeated a plurality of times so that the reinforcing portion 250 may be composed of three, four or more layers.

6 (a) and 6 (b), a bridge member 200 is formed to have a shape of 'U' shaped in an open shape in which both upper and lateral sides are open, In this case, the load applied by the load placed on the upper portion of the upper plate 100 is smaller than the load applied to the upper portion of the upper plate 100, The load bearing capacity can be improved and the deformation due to the load can be reduced.

In addition, when the leg members 200 are formed so as to have an outwardly convex circular arc shape in both longitudinal sides of the leg member 200, there is an advantage that stacking of the leg members 200 is performed more smoothly during transportation of the pallet 10 .

A concave groove 240 having an arc-shaped cross section protruding inward may be formed on the lower surface of the leg member 200. The concave groove 240 functions as a cushion to be formed on the upper surface of the upper plate 100 And to absorb the impact caused by the load applied from the loaded load.

At this time, a seating groove 326, which is the same as the shape of the groove 240 of the leg member 200, is formed in the receiving member 320 of the lower plate 300 to be described later to improve the cushioning function by the groove 240 .

Next, the lower plate 300 is connected to the lower portion of the upper plate 100 by the leg member 200, and supports the pallet 10 so that the pallet 10 can be stably placed on the ground. As shown in FIG. 3, A second outer frame 310, and a receiving member 320. [

More specifically, the second outer frame 310 is formed in a U-shape and constitutes a rim portion of the lower plate 300, and has the same structure as the first outer frame 110 of the upper plate 100 Lt; / RTI >

The support member 320 is vertically connected to the inside of the second outer frame 310 by a welding method or the like and supports the lower end of the leg member 200 to support the pallet 10 And so on.

The support member 320 includes a support portion 322 having a horizontal surface on which the leg member 200 is placed and a support portion 322 formed on both ends of the support portion 322 and bent on both sides of the support member 322, And a vertical portion 324 configured to surround the vertical portion 324. The vertical portion 324 has a fastening portion 324a formed at an upper end thereof so as to be fastened to the coupling groove 230 formed at a lower portion of the leg member 200 Consists of.

4 (b), a hook-shaped fastening portion 324a, which is bent inward, is formed at the upper end of the vertical portion 324 and is formed on both sides of the lower portion of the leg member 200 The fastening portion 324a is engaged with the coupling groove 230 so that the leg member 200 can be coupled to the supporting member 320. [

Since the pallet 10 according to the present invention including the leg member 200 and the support member 320 is made of a steel material having elasticity such as steel, The vertical member 324 of the support member 320 extends to both sides so that the leg member 200 enters the support member 320 and the support member 320 When the fastening portion 324a of the fastening portion 324a reaches the position of the coupling groove 230 formed in the leg member 200, the vertical portion 324 is again narrowed by the elasticity, The leg member 200 and the supporting member 320 can be coupled with each other by a simple process so that the fastening of the upper plate 100 and the lower plate 300, So that it can be easily performed in the field.

The support portion 322 of the support member 320 may have at least one second force portion 322a formed therein. As shown in FIG. 4B, The leg member 200 and the support member 320 are formed in a position corresponding to the first forceps 220 formed on the member 200 so that the support member 320 can stably support the leg member 200 So as to improve the structural strength of the support member 320. [0064]

Next, the lower plate 300 may further include a transverse member 330 connected to the support member 320 in the transverse direction. The transverse member 330 may be formed by a welding method or the like And is connected between the support members 320 to improve the structural strength of the lower plate 300.

3, the transverse member 330 may have a U-shaped cross section or may have a square pipe shape to minimize the overall weight increase while improving the structural strength of the lower plate 300 . &Lt; / RTI >
