摘要
Vandalism resistant building modules suitable for detention and secured storage facilities provide good architectural properties and significant resistance to noise, fire and impact. Thus, steel shell modules are welded together to produce steel inner and outer walls (11, 12). The modules contain strengthening and bullet deflecting internally directed steel baffles (30, 31) and various types of insulating materials. Construction is facilitated by providing modules that are welded together along only two lines coinciding with mating end positions on the steel plate inner and outer walls (11, 12). Three steel panel pieces are formed into a module, each being partly triangular in cross section so that only one weld seam (22) between two of the panels is required in assembling the three pieces which thereby form the internal baffles (30, 31) at angles for deflecting bullets.
