Reserve/cavity conserving body for concrete wall of building, has annex modules fixed at top of base module, where bottom surface and heights of annex modules are identical to top surface and lesser than height of base module, respectively

摘要

The body has annex modules (3, 4) fixed at top of a base module (2) by an assembling unit (10). A module group is associated to the module (2) whose extension by the modules (3, 4) is smaller with respect to the height of the module (2). The module (2) has a magnet (9) to position and maintain the module (2) on branches. The modules are widened along same slope and has a polygonal base, where a bottom surface of the modules (3, 4) is identical to a top surface of the module (2). The height of each annex module is lesser than the height of the module (2). The modules are formed of resin blocks.
