PERPENDICULARITY MEASURING METHOD USING A TOTAL STATION FOR PRECISE CONCRETE CONSTRUCTION

摘要

PURPOSE: A perpendicularity measuring method using a total station is provided to enable precise concrete construction according to designed position by securing the position of a reference point on each layer of a high-story building.;CONSTITUTION: A perpendicularity measuring method using a total station for precise concrete construction is as follows. Four initial reference points constituting a square are set on the floor of a first layer. Concrete is placed and cured on the floor of the first layer, and the displacements of the four initial reference points are measured and corrected using a total station(T). Concrete is placed and cured on the floor of the upper layer, and the four reference points set on the initial layer are vertically transferred and set on the upper layer using the total station. The matching of the reference points on the initial layer and the reference points on the upper layer is checked using the total station.;COPYRIGHT KIPO 2012
