PROBLEM TO BE SOLVED: To construct a reinforced concrete building under noiseless and quiet work environment in a short construction term at the construction site by using combination of a precast method and a prestressed method. SOLUTION: A concrete wall W formed of integrated heat insulating panels 2 comprising an extrusion molding cement plate 2A and a heat insulating layer 2B at an external surface and provided with gas permeable layers AG, AG' on the inner side is integrated with a concrete floor slab part S with a width which is the same as that of the concrete wall W at a curved joining part C1. A bearer B projected from a floor slab surface Sf is provided on an upper end of the concrete wall W, and a cut out H1' arranged in an adequate place is provided in a lower front surface of the bearer B of the concrete wall W, and a precast concrete body 1 for precast introduction which has a cut out hole H1 formed by cutting off of a heat insulating panel piece 2' is provided at a position corresponding to the cut out H1. Precast concrete bodies 1 are mutually strained and fixed on upper, lower, left, and right side by PC steel materials 7A, 7B in an opposed joined configuration of front end sides SF of the concrete floor slab. The external heat-insulation prestressed building is constructed by fitting the cut-off heat insulating panel piece 2' in the cut out hole H1 of the heat insulating panel.
