Abstract

The present invention relates to a support which is used for loading steel materials and has a hole formed in an I-beam structure on a plastic body.

Description

Plastic support for steel material

The present invention relates to a steel pedestal for use in loading steel.

Since the existing steel support is used as a pine tree which depends on imports, it is difficult to sterilize and disinfect according to the insecticide, and it is difficult to use it in terms of strength and weight. In order to solve this problem, It is imperative to develop semi-permanent materials.

Registration Utility Model No. 20-0420877

It is an object of the present invention to overcome the above-mentioned problems and it is an object of the present invention to provide a steel product having high impact strength, deformability and high impact strength at low temperature for use as a steel plate, Since it requires high impact physical properties to be prevented, it has excellent strength and various physical properties as shown in Table 1, and provides a plastic support which can withstand the load even when the load is dispersed as shown in Table 1 .

In the present invention, a method of producing a plastic bearing by extruding a material mixed with 90% of high-density polyethylene and 10% of low-density polyethylene in the field of various steel products.

In the production of plastic pedestals, it is shaped like a figure on the surface, which is characterized by a structure in which the load is dispersed in the field.

The present invention can be used in a steel manufacturing plant to substitute a special wood, which is used for the production of steel products,

By using polyethylene resin, the environment can be recycled and it can be used several times instead of one or two times without being affected by changes in weather (snow, boiling) compared to existing wood, thus reducing manufacturing cost.

BRIEF DESCRIPTION OF THE DRAWINGS Fig.

Hereinafter, the technical idea of the present invention will be described more specifically with reference to the accompanying drawings.

SUMMARY OF THE INVENTION The present invention has been made to solve the problems of the prior art,

As a means, 90% of a high-density polyethylene resin having excellent impact resistance is mixed with 10% of low-density polyethylene having good deformability and extrusion-molded as shown in Fig.

As compared with the conventional abobe wooden support, the strength was improved by more than three times in the impact strength and the deformability. As shown in Fig. 1 of the present invention, by extruding into the I-beam structure, the load received on the support surface This makes it more durable and has a better effect than the conventional special purpose baby cradle.

[Example 1]

The raw material mixing ratio of the injection molding material was prepared by extruding 90% of high-density polyethylene resin and 10% of low-density polyethylene resin into an I-beam structure using a melt extruder having a length and a length of 100,000 mm shown in the figure

As shown in the figure, the extruded material is extruded in the form of an I-Beam structure on the inner surface of the extruded material to improve the septum strength by dispersing the load of the support, and the embossed shape is formed on the surface,

1. beam 2. beam hole

Claims (2)
