Composition of precast concrete wall and precast concrete column for outdoor to sustain external force

摘要

PURPOSE: A precast concrete outer wall system pressed by external force is provided to improve quality, to make repeat production possible, to mass-produce, to reduce the construction period in a job site, to increase productivity by manufacturing a precast concrete outer wall as well as an outer column in a factory and to reduce labor costs in a job site and an input of materials and to simplify on the arrangement of a job site by assembling and connecting simply in a job site. CONSTITUTION: A precast concrete outer wall system pressed by external force comprises an external column(10) manufactured by precast concrete in a sectional shape having an appointed width, height and length and supporting an upper structure, several external walls(20) arranged to the external column(10) and manufactured by precast concrete in a sectional shape having an appointed width, height and length against external force, wherein the external walls(20) are connected with the external column(10) by a cast-in-place concrete(30) and contains a wide inner concrete layer(130) and a narrow outer concrete layer(140).
