LAMINATED UNIT OF CERAMIC SHEET

摘要

A laminated unit of a ceramic sheet is provided to prevent a fixing unit from being loosed according to the repetition of vertical load by absorbing impact load through slits formed in each plate. A laminated unit(10) of a ceramic sheet includes top and bottom plates(11,12), a plurality of posts(13), a fixing unit(14), and a pressing bar(16). The top and bottom plates are formed in a shape of a plane and a plurality of slits(30) are formed across vertical cross-sections of the top and bottom plates. Top and bottom ends of the posts are closely connected to the corresponding surfaces of each plate to horizontally support the top and bottom plates. The fixing unit has a bolt(14a) inserted into a contact portion between the posts and the plates and a button(14b) encompassing the bolt. The pressing bar is attached to a bottom surface of the bottom plate and presses a top surface of a bottom laminated ceramic sheet.
