A modular construction system (10) is provided, the preferred embodiment of which is directed toward the construction of structural walls (26). The construction system (10) employs precast wall units (12) and a variety of spacer/tensioning, spacer, tensioning, and extension assemblies (14, 16, 18 and 20). The wall units (12) contain a plurality of cavities (44) and are made of concrete with side walls (36) reinforced with prestressed tension wires (48). In the process of constructing a wall (26), the wall units (12) are stacked one upon the other onto threaded wall bars (24) that extend upwardly from a foundation (22). The spacer/tensioning assembly (14) and the spacer assembly (16) provide alignment during the stacking process and also create mortar joints (52). The spacer/tensioning assembly (14) and the tensioning assembly (18) are utilized in conjunction with the wall bars (24) to tension the wall units (12) onto a lower wall units (12) and the foundation (22). When stacked, the internal structure of the wall units (12) creates vertically and horizontally extending passages (85 and 86) into which grout (84) is poured to create a monolithic wall (26).

La présente invention concerne un système de construction modulaire (10) dont le mode de réalisation préférentiel vise la construction de gros murs (26). Ce système de construction (10) utilise des éléments de murs préfabriqués (12) et divers ensembles d'écartement-traction, d'écartement, de traction et d'allongement (14, 16, 18 et 20). Les éléments de murs (12) comportent diverses cavités (44) et ils sont faits de béton, les parois latérales étant renforcées par des fils de traction précontraints (48). Durant le processus de construction d'un mur (26), les éléments de murs (12) sont empilés sur des tiges murales filetées (24) qui montent depuis les fondations (22). L'ensemble (14) d'écartement-traction et l'ensemble d'écartement (16) assurent l'alignement pendant l'empilage et créent aussi des joints pour mortier (52). L'ensemble d'écartement-traction (14) et l'ensemble de traction (18) sont utilisés, de concert avec les tiges murales (24), pour tirer les éléments de murs (12) sur des éléments de murs placés plus bas (12) et sur la semelle de fondations (22). Quand les éléments de murs (12) sont empilés, leur structure intérieure crée des passages verticaux et d'autres horizontaux (85, 86) dans lesquels on verse du mortier (84) pour obtenir un mur monolithique (26).
