Description

INSTALLATION DEVICE OF DOUBLE FLOORS WITH FRAME SUPPORTED BY BEAM}

The present invention relates to a double-bottom installation device having a frame for supporting a beam element, and more specifically, by supporting a bottom surface of the panel via a frame installed on the top of the beam element, the weight of the panel is reduced and the resistance to transverse load is increased. It relates to a double-floor mounting device with a frame for supporting beam elements that can be improved.

In general, almost all operations performed in the manufacturing process for high-precision parts or products are performed in a clean room with high cleanliness. Such a clean room is equipped with a double-bottom system that ensures a high level of floor plan for the stable installation of various process equipment and the implementation of precise functions of the transfer equipment.

The conventional double-bottom system can be largely divided into a pedestal support structure and a beam element upper installation structure.

First, the pedestal support structure is a structure that supports and connects the four corners of the panel with individual pedestals. It has the advantage of being lightweight, quick to install, easy to adjust horizontally to the panel, and high rigidity, but the size is about 600mm. Since the pedestal must be installed for each panel, the lower space of the panel becomes narrow, which limits the installation of piping, wire rods, and other devices.

In addition, the beam element upper installation structure is placed on the large post (Primary Beam, Main Beam) on the upper part of the beam, and the secondary beam (Secondary Beam, Sub Beam) is placed on the upper part of the beam. It consists of a structure that installs a double-floor panel on the upper part. Since the post spacing can be set differently depending on the rigidity of the main beam, it is possible to secure a wider space under the panel to accommodate various types of under-floor utilities. Therefore, it is often used as a substructure of a large clean room.

However, in the upper part of the beam element, since the level is adjusted from the lower part of the auxiliary beam, the double floor panel is placed on the upper part of the auxiliary beam, so individual horizontal adjustment to the panel is not easy and the rigidity is low compared to the weight of the structure. There are disadvantages.

In addition, the structure of the double floor for clean room installation makes the panel lighter and transverse in spite of various attempts within the basic structure of the pedestal structure and the beam element upper installation structure due to the enlargement of the clean room and diversification of the production process. Limitations have been shown in improving the resistance to load.
