Abstract

The invention relates to a frame part of an installation casing comprising: an installation panel for receiving equipment to be installed and a frame plate. In order to achieve a structure, in which the equipment installed in the installation casing can be protected from external vibration, a space between the installation panel and/or the frame plate is provided with protruding dents, and the installation panel and the frame plate are joined together by means of the dents.

Claims

1. A frame part of an installation casing, comprising:

an installation panel for receiving devices to be installed, and

a frame plate, and in which

the installation panel and/or the frame plate comprises dents which protrude into a space between the installation panel and frame plate,

the installation panel and frame plate comprise an angle,

the dents are arranged on both sides of the angle of the installation panel and frame plate, and

the installation panel and frame plate are fastened to each other through the dents on both sides of the angle of the installation panel and frame plate.

2. The frame part as claimed in claim 1, wherein the installation panel and frame plate are fastened to each other through the dents with intangible riveting.

3. The frame part as claimed in claim 1, wherein at least part of the area of the dents is perforated.

4. The frame part as claimed in claim 1, wherein

the installation panel and frame plate have dents settling against each other, and

the installation panel and frame plate are fastened to each other through the dents that settle against each other.

5. The frame part as claimed in claim 1, wherein the dents are mainly conical in shape.

6. A method for manufacturing a frame part of an installation casing, the method comprising

taking into use an installation panel and a frame plate,

selecting for shaping the installation panel or frame plate, or alternately both the installation panel and the frame plate, to form dents at predetermined locations in the selected plate,

bending the installation panel and frame plate to form an angle in the installation panel and frame plate so that there are dents on both sides of the angle,

setting the installation panel and frame plate to face each other in such a manner that the dents protrude into the space between the installation panel and frame plate, and

joining the installation panel and frame plate to each other through the dents.

7. The method as claimed in claim 6, wherein during the shaping, perforations are formed in the areas where the dents are made.

8. The method as claimed in claim 6, comprising joining the installation panel and frame plate to each other through the dents by using intangible riveting.
