Patent ID: 7832158

Claim:
A wall structure having an inner area of a framing or framework divided into a plurality of openings by metal frame bars arranged in a lattice pattern, further comprising: polygonal surface glass panes fitted in a subset of said plurality of openings to close said subset of said plurality of openings; metal plates fitted in remaining openings to close said remaining openings; spacers, softer than said surface glass panes and said frame bars, formed of a hard material with Young's modulus (E) at 1,000-70,000 N/mm 2 , for transmitting external forces through said frame bars and said polygonal surface glass panes are mounted in said subset of said plurality of openings between end surfaces extending along four sides of said polygonal surface glass panes and said frame bars, said spacers not adhering to said polygonal surface glass panes are spaced from corners of said surface glass panes; and elastic cushioning members, softer than said spacer, formed of a soft material with Young's modulus (E) at less than 1,000 N/mm 2 , for preventing transfer of external forces from the frame bars are mounted between the end surfaces around the corners of each surface glass pane and the frame bars, and between glass surfaces of the surface glass pane and the frame bars.
