BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a plate material pressurizing apparatus, and more particularly, to an apparatus for performing a pressurization test on a plate material.

Generally, when pressure measurement test is performed on a plate-type material, fix the upper and lower portions of the specimen, narrow the gap between the upper and lower sides, and measure the shape and damage of the specimen.

When the compressive stress applied to the specimen is measured, the warpage occurs frequently in the plane direction of the specimen due to the characteristics of the specimen.

As a result, the compressive stress applied to the specimen is not fully transferred, and the force is dispersed in the other direction, so that the compressive stress acting on the specimen can not be precisely measured.

In most cases, the compressive stress measurement apparatus of a generally used plate type specimen is measured by using a pressure applied to a member on one side of the specimen when the pressurization is performed.

Therefore, it was difficult to understand how the compressive stress directly affects the specimen.

In addition, the size and shape of the specimen may vary. In order to perform the pressure test on the corresponding specimen, it has been difficult to produce a corresponding device separately.

Therefore, it is necessary to develop a device capable of accurately measuring the compressive stress applied to a specimen of a plate-like material, and it is necessary to develop a device capable of measuring pressurization in accordance with various specimens.

It goes without saying that the first plate 100 and the second plate 200 are spaced apart from each other by a width not to interfere when the specimen P is stretched or compressed in the upward and downward directions.

Since the fixing member 320 fixing the upper portion of the specimen P can directly press the fixing member 320, the fixing member 320 can be inserted into the gap between the first plate 100 and the second plate 200 .

Needless to say, there is no limitation on the number and shape of the fixing member 320 and the lower fixing member 420 that can fix the specimen P in the up and down directions.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or scope of the invention as defined in the appended claims. .
