Description

Structuralally stable sheet of steel sheet packaging {SUPPORTER FOR PACKING STEEL PLATE HAVING STABLE STRUCTURE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steel plate packaging pedestal, and more particularly, to a steel plate packaging pedestal used for packaging for transporting and loading steel sheets cut to a certain standard.

In general, a cold rolled steel sheet or a hot rolled steel sheet produced in an ironworks is cut to an appropriate size for sale after production, and packed in a stacked state in which several sheets are stacked in order to store or transport the cut steel sheet to a specific place. At this time, supporting the steel sheet to be loaded is a steel plate packaging pedestal.

Conventionally, the steel plate packaging pedestal made of wood is used a rigid wood such as Abiton (Apitong), a lower pedestal having a rectangular cross-section arranged in a plurality of horizontally spaced at a predetermined interval, and a rigid wood such as avidone And an upper pedestal having a rectangular cross section for loading a steel sheet in a state where a plurality of the plurality is arranged in a horizontal state at a predetermined interval in the state intersected with the upper part of the lower pedestal, wherein the lower pedestal and the upper pedestal are fixed to each other with a nail. Was fixed.

As described above, the steel plate packaging pedestal made of wood uses firstly imported timber, which increases raw material costs, which requires a lot of manufacturing cost. Second, the heavy weight of the pedestal itself increases the transportation cost. Third, the lower pedestal and the upper pedestal. Fixing nails used to fix them easily corroded, shortening the life span of the pedestals, as well as the risk of safety accidents.

In order to improve this, Korean Patent No. 10-0806700 (registered on February 18, 2008, title “Steel Sheet Packaging Stand”) proposes a stand as shown in FIG. 6.

However, the steel plate packaging pedestal proposed in Korean Patent No. 10-0806700 as described above has the following disadvantages or problems.

First, the stepped portion formed by the trapezoidal shape shown by reference numeral 21 formed on the upper surface of the pedestal and the bracket (connection band plate) shown by reference numeral 30 actually causes pressing marks on the surface of the steel sheets. Will be. If a mark is generated during transportation due to the stepped portion as described above on the surface of the steel plate placed on the pedestal, there is a disadvantage that the function as a product is lost.

Second, the upper surface of the upper pedestal is open, so that the phenomenon of gradual inward due to the side impact occurs. That is, the upper pedestal is a structure that is very vulnerable to side impact. In order to reinforce this, the bracket shown by reference numeral 30 is reinforced, but the steel sheet is primarily damaged by the stepped shape formed by the portion, and in other areas except the portion, the sheet is crushed inward by the side impact. Is inevitable. In addition, such an gradation is a constant angle is formed in the upper edge portion by the development can make a longitudinal mark on the steel sheet.

Third, the upper surface of the lower pedestal 10 is a flat structure is not welded properly when welding with the upper pedestal 20. In detail, both the lower pedestal and the upper pedestal are made of steel, but the surface of the lower pedestal and the upper pedestal are plated with hot-dip galvanized material so that the hot-dip galvanized portion of the lower pedestal and the upper pedestal are not substantially welded to the steel plate and the steel pedestal. The molten zinc plated part is melted by heat, but rather a structure that prevents bonding by welding.

In particular, Figure 1 is a perspective view schematically showing the overall appearance of a steel plate packaging pedestal according to one preferred embodiment of the present invention, Figure 2 is a steel plate packaging pedestal according to one preferred embodiment of the present invention shown in FIG. Figure 3 is a view showing a view from above, Figure 3 is a view showing a view from below the steel plate packaging pedestal according to one preferred embodiment of the present invention shown in Figure 1, Figure 4 is shown in Figure 1 It is a side cross-sectional view of the base plate packaging stand according to one preferred embodiment of the present invention.

1 to 4 together, the steel plate packaging pedestal according to one preferred embodiment of the present invention is the lower pedestal 110 and the upper pedestal 120 is vertically cross-linked with respect to the upper surface of the lower pedestal 110 It includes. The lower pedestal 110 and the upper pedestal 120 is at least partly or entirely made of steel.

The lower pedestal 110 is arranged side by side as shown in Figures 1 to 4, each has a cross-section of the upper open trapezoidal shape of the lower side is smaller than the length of the upper side. In order to form such a trapezoidal cross section, a process of bending a flat iron plate into a trapezoidal shape is required. Of course, each steel plate may be connected to each other by a method such as welding to realize a trapezoidal shape. However, in addition to the welding process, the welding process may be added and the reliability of the welded part may not be easily obtained. It would be desirable to implement a trapezoidal shape rather than a bending process. In addition, a plurality of vertically long emboss 140 is formed on the side of the lower pedestal 110, the rigidity of the lower pedestal 110 is increased by these emboss 140 to prevent deformation due to the bending load It helps. For example, by forming these emboss 140, even if a cold rolled steel sheet having a thickness of about 3.0 mm is to be replaced by a cold rolled steel sheet having a thickness of about 1.4 to 1.5 mm, the strength is similar.

The upper pedestal 120 is cross-coupled to the upper surface 111 of the lower pedestal 110 in a direction perpendicular to the upper surface of the lower pedestal 110. That is, the open lower surface 121 of the upper pedestal 120 is coupled to the upper surface 111 of the lower pedestal 110. At this time, the lower pedestal 110 and the upper pedestal 120 is coupled by welding, such as spot welding. In addition, as an embodiment of the present invention, for example, a circular emboss 150 is formed on the upper surface of the lower pedestal 110 or the upper surface or both of the upper pedestal 120, the lower pedestal ( 110 or the zinc plated plated on the surface of the upper pedestal 120 is melted and quickly gathered into the embossed steel is exposed to form a strong welding bond between each other. In the prior art, for example, when the spot welding of the lower pedestal 110 and the upper pedestal 120, the molten zinc plated material is present in a molten state in place, it is a factor that prevents mutual welding coupling.

Unlike the lower pedestal 110, the upper pedestal 120 coupled to the lower pedestal 110 has a cross section of a lower open trapezoidal shape having a lower side larger than the upper side as shown in FIGS. 1 to 4. . In order to form such a trapezoidal cross section, a process of bending a flat plate like a lower pedestal 110 into a trapezoidal shape is required. Of course, each steel plate may be connected to each other by a method such as welding to realize a trapezoidal shape. However, in addition to the welding process, the welding process may be added and the reliability of the welded part may not be easily obtained. It would be desirable to implement a trapezoidal shape rather than a bending process. In addition, on the side of the upper pedestal 120 is formed a plurality of vertically long emboss 140, such as the lower pedestal 110, the rigidity of the upper pedestal 110 is increased by these emboss 140 It helps to prevent deformation due to flexural load. For example, by forming these emboss 140, even if a cold rolled steel sheet having a thickness of about 3.0 mm is to be replaced by a cold rolled steel sheet having a thickness of about 1.4 to 1.5 mm, the strength is similar.

In addition, for example, a dot or circular emboss 150 is formed on the upper surface of the upper pedestal 120, and the rigidity of the upper pedestal 110 is increased by these embossing 150 to prevent deformation due to the bending load. It helps.

In addition, according to the present invention, the angle of the trapezoidal obtuse corner portion of each of the lower pedestal 110 and each upper pedestal 120 is advantageously an angle of more than 90 degrees to less than 100 degrees. If these angles are too large, they are crushed by the load of the steel plate placed on the upper portion, and if the angle is too small, the circular shape of the cross section may be damaged due to the buckling deformation occurring at the bending load.

In addition, according to a preferred embodiment of the present invention, at least the upper portion of the upper portion and the lower portion of the lower portion of the upper pedestal and the lower pedestal of the coupling portion of the lower pedestal 110 and the upper pedestal 120 It is preferable that the reinforcing plate 160 is welded to the portion where the pedestal is coupled, starting from the lower edge of the lower pedestal to a part of the lower surface of the upper pedestal. By this reinforcement plate 160 is to prevent deformation by a separate transport machine.

The steel plate packaging pedestal according to the present invention structured as described above has a lower cross-type trapezoidal cross-section of the lower side of which the length of the lower side is larger than the length of the upper side, unlike the prior art. Such defects do not occur.

In addition, since the open lower portion of the upper pedestal is coupled to the upper surface of the lower pedestal, a bracket for preventing a phenomenon such as a gap in the prior art is not required. In addition, since there is no such bracket, it is possible to avoid the occurrence of marks.

In addition, since there is no open portion on the upper surface of the upper pedestal, the gradation phenomenon does not occur even by the side impact.

Furthermore, durability is improved because a structure for reinforcing the bracket and the support orientation of the lower pedestal for reinforcing the lower pedestal is formed.

In addition, since the emboss is formed on the upper surface of the upper pedestal itself improves durability. In addition, a plurality of embosses are formed on the side in the longitudinal direction, thereby improving side durability.

Moreover, the concave emboss is formed in the welding part of the upper pedestal and the lower pedestal so that the galvanizing material, which prevents the mutual bonding during welding, is filled with steel and the steel material is exposed, so that the mutual bond becomes very strong. will be.
