PROBLEM TO BE SOLVED: To need no skilfull technique and execute a void slab with a small number of workers in a short period, by assembling an easily portable void form made of light-weight raw materials in metal fixings for void blocks and connecting them both lengthwise and crosswise. SOLUTION: Easily portable void forms 2,... made of light-weight raw materials having a certain length are assembled in metal fittings 1, 1 for void blocks to form a plurality of void form-assembled blocks. These void blocks are laterally connected to each other by binding mutual metal fittings 1 and further, vertically connected by using connecting projections and recessions of the void forms themselves. Welded wire nettings for the upper and lower end reinforcements 3, 3, 4, 4 which are fabricated in a factory to have transferable dimentions, and the void blocks and simple swell-preventive metal fittings 5... assembled in the metal fittings 1, are separately sent in or these are sent in as a half unit. Thereafter, these are connected together. In this way, the structure can be constructed by a small number of workers in a short period.
