Lightweight Interior Sidewall and Method for Fabricating the Same

A method for fabricating an interior sidewall, comprising:

• (1) providing lightweight slabs having at least the same thickness and length, wherein each slab has a longitudinal groove defined in a central region of two sides thereof;
• (2) fixing an elongated clamp of a reverse U-shape on a ceiling at a location for receiving the placement of the sidewall, wherein the clamp has an opening oriented downward and retains a flexible element therein;
• (3) vertically erecting the slabs adjacent to each other on a floor, and engaging an upper edge of each slab into the elongated clamp;
• (4) locking a bottom edge of each of slab with a support element used for adjusting the height of each slab;
• (5) fixing a baseboard at a lower portion of a front surface and a rear surface of each slab, wherein the baseboard is tightly adhered on the floor;
• and
• (6) forming an injection hole at an upper region of an interface between the two slabs for injecting a viscous binder substance that fills up each of the longitudinal grooves and a gap between the bottom edge of each slab and the floor.
