Structural sandwitch plate systems are an innovative way to combine metal plates with a polyurethane elastomer core, providing a new alternative to large ship repair projects, and for structural steel in civil construction or offshore plant construction. It also has the incredible potential to simplify and improve the way you use it.

This structure sandwich plate system uses a sandwich type structure in which a polyurethane elastomer core is sandwiched between two metal plates instead of a conventional steel structure in which a reinforcement is welded to a single steel plate to form a structure. Thus, when compared to traditional steel structures, the structural sandwich plate uses less steel to achieve the same strength, simplifies the production process and exhibits several other excellent structural properties.

When using steel plates in large-scale civil engineering construction or offshore plant constructions using these structural sandwich plates, the desired strength can be achieved without the need for additional reinforcement such as a bulb flat welded on the steel plate to prevent warpage or warping.

On the other hand, the manufacturing process of the structural sandwich plate according to the standard is as follows.

To form. Then, the upper surface of the upper steel plate is pressed with a press.

Thereafter, an inlet and an air outlet are formed on the upper steel plate side, and an elastomer layer is formed between the upper and lower steel plates by injecting and curing a polymer such as an elastomer into the space through the inlet.

In this way, since the sandwich plate of the standard specification is produced in such a way that the press, the surface plate, etc. of the production line are matched to the designed standard, the press, the surface plate, etc. of the production line should be prepared separately when the customer requires a specific standard out of the standard. In addition, the production efficiency is lowered as the arrangement of each equipment is newly changed.

The present invention has been made in view of the above, and the structural sandwich plate of the structural sandwich plate which can improve the production efficiency by easily modifying the structural sandwich plate of a specific standard to meet the needs of the user without changing the existing production line Its purpose is to provide a method for modifying the specification.

One aspect of the present invention for achieving the above object is a method of modifying the standard of the structural sandwich plate to modify the structural sandwich plate of the standard specification to a specific standard corresponding to the requirements of the user, a part of the structural sandwich plate specific specification Cutting corresponding to forming a cut edge in the structural sandwich plate; And a finishing perimeter bar installation step of installing a finishing perimeter bar on the cut edge of the structural sandwich plate.

The cutting step is characterized by cutting a portion of each of the elastomer layer interposed between the upper and lower steel plate, the perimeter bar, the upper and lower steel plate of the structural sandwich plate.

The finishing perimeter bar installation step is to remove the part of the elastomer layer on the cut edge of the upper steel plate and the lower steel plate of the structural sandwich plate to form a space, characterized in that to install the finishing perimeter bar in the space. .

After applying the adhesive to the space portion is inserted into the finish perimeter bar, the finish perimeter bar is characterized in that the welded with the perimeter bar, the upper steel plate, the lower steel plate of the cut structure sandwich plate, respectively.

Another aspect of the present invention is a method of modifying the standard of the structural sandwich plate for modifying to a specific standard corresponding to the requirements of the user by cutting a part of the structural sandwich plate of the standard specification, cutting a part of the structural sandwich plate according to the specific specification After finishing the cut portion of the structural sandwich plate is characterized in that the finish by the perimeter bar.

According to the present invention as described above, since the standard of the structural sandwich plate can be easily modified to the specific standard in response to the request of the user, it is possible to effectively cope with the demand of the user without changing the existing production line, and also from the standard specification to the specific There is an advantage that can improve the production efficiency of the standard sandwich plate.
