Title:
SEMICONDUCTOR FACTORY GRID BEAM STRUCTURE AND METHOD FOR CONSTRUCTING SAME
Document Type and Number:
WIPO Patent Application WO/2019/066136
Kind Code:
A1
Abstract:
The purpose is to provide a semiconductor factory grid beam structure and a method for constructing same. The semiconductor factory grid beam structure is installed inside a semiconductor factory and comprises: posts which are vertical columns erected in the longitudinal and the transverse direction at predetermined intervals; unidirectional beams cradled on and fixed to the upper portions of two adjacent posts, thereby connecting the upper portions of the posts in the transverse direction; and rectangular grid beams installed so as to fill the rectangular horizontal area formed and surrounded by the unidirectional beams. Protruding stepped portions are formed on the side surfaces of the unidirectional beams, and recessed stepped portions are formed on the side surfaces of the grid beams. The bottom surfaces of the stepped portions on the side surfaces of the grid beams are cradled on the upper surfaces of the stepped portions on the side surfaces of the respective unidirectional beams, thereby installing the grid beams. Mortar is injected into a gap between the end portions of two unidirectional beams joining at the upper portions of the posts and into a gap between the side surfaces of the unidirectional beams and side surfaces of the grid beams. Accordingly, the end portions of the unidirectional beams are bonded and fixed to each other, and the unidirectional beams and the grid beams are bonded and fixed to each other, thereby providing a means capable of completing the coupling in a much shorter time than in the case of pouring and curing concrete. In addition, the structure is large enough to endure vibrations, thus the coupling between the grid beams, the unidirectional beams, and the posts can become more robust.
