Description

Device for supporting pipe installed in manufacturing facilities

The present invention relates to a pipe support device for supporting a pipe installed in a manufacturing facility, and more particularly, to a pipe supporting device for supporting a pipe installed through the lower and upper floors of the manufacturing facility.

In general, a building or facility in which a device such as a semiconductor is manufactured is called a line, and such a line is made of multi-layered fabs (FABs).

For example, a wafer manufacturing line of 200 mm or less has a two-layer structure of FAB (C/R: Clean Room) and Sub FAB (Plenum). Here, the fab (FAB) is a clean room (C/R) where semiconductor processing is carried out, and is an area where most workers perform work and operation and maintenance of production facilities are performed. A vacuum chamber essential for major semiconductor processes such as etching process and chemical vapor deposition can be installed in the FAB.

Sub FAB is a space in which auxiliary facilities are located to provide production facilities with chemicals necessary for the process, such as gas and chemicals, and to remove (exhaust) residual chemicals after the process is carried out.

Recently, in order to increase production efficiency, as the wafer size increases to 300 mm and the equipment density also increases, the structure of the sub-fab consisting of two layers of CSF (1st Plenum) and FSF (2nd Plenum) is also adopted.

Pipes passing through the multi-layered FABs are installed in this manufacturing facility (line). For example, a vacuum pipe connecting a vacuum pump installed in the Sub FAB of the lower layer and a vacuum chamber installed in the FAB (C/R) of the upper layer may be installed.

Korean Patent No. 10-1802286 (hereinafter referred to as 'prior art') discloses a support device for supporting a vacuum pipe for semiconductor and display manufacturing facilities.

Such a conventional support device has a problem in that the sleeve member 110 protrudes upward from the bottom 5 of the fab (FAB) to install equipment in the fab, or to obstruct the movement of the worker.

In addition, when the vacuum pipe 10 is removed due to facility change and the sleeve member 110 is to be disassembled, the opening of the floor 5 is separated by disassembling the screw coupling the sleeve member 110 to the floor 5 . It is cumbersome because it has to be blocked with a member, and there is an inconvenience in that the sleeve member 110 must be separately stored in case the vacuum pipe 10 is to be installed again later.

The problem to be solved by the present invention is, first, to provide a pipe support device with a lowered height protruding from the floor.

Second, it is to provide a pipe support device capable of closing the pipe installation path formed on the floor without removing all the pipe support devices even when the pipe is dismantled.
