Abstract: A glass modular construction block is provided with a form-fitting frame of an integral foam material, and wherein the frame on the impact surface is provided with projections and recesses, which permit a firm plug-in connection. Along the narrow sides, the frame includes sealing projections. The space between the sealing projection serves for the insertion of reinforcement bars made of flat sections, which are provided with through-going openings for the plug-in projections. Setting of the glass modular construction blocks is accomplished without any additional adhesive means, so that a wall or wall portions constructed from such glass modular construction blocks can be disassembled, and so that the glass modular construction blocks are reusable.
