INSTALLATION METHOD OF AS-CAST CONCRETE STRUCTURE

摘要

PURPOSE: To lessen deterioration, contamination, discoloration, etc., and to increase the number of use times of forms by molding a concrete body with the forms formed with molding surfaces as rough surfaces, then conditioning the surfaces with surface conditioning materials to form patterns and subjecting the surfaces to top coating with a transparent waterproof agent. ;CONSTITUTION: The surfaces 3 of the concrete body 3 formed by packing ready mixed concrete into the wooden forms 1, 2 having many pieces of ruggedness on the molding surfaces 1a, 2a used ≥2 times and curing this concrete are washed. Next, the defect parts 4 generated on the surfaces 3a are packed to the same color by the first resin mortar ground surface conditioning agent 6 of a relatively high viscosity contg. pigments. The second resin mortar upper surface conditioning agent of a relatively low viscosity contg. pigments is then applied over the entire part of the surfaces 3a to form upper surface layers 7 of the prescribed thickness and the same color. Further, the surfaces of the upper surface layers 7 are impregnated with compounded resin liquids of prescribed colors by a pattern forming means, by which patterns are formed. Finally, a transparent waterproof material is applied on the surfaces of the upper surface layers 7 to form top coats 9, by which the as-cast concrete structure A is obtd.;COPYRIGHT: (C)1996,JPO
