WHITEWASH STOPPER STRUCTURE FOR CONCRETE PLACING JOINT, AND INSTALLATION METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a method that prevents whitewash from flowing out to a beam side from a concrete placing joint, when high-strength and high-fluidity concrete is placed on a column side and ordinary concrete is placed on the beam side and a slab side.;SOLUTION: A beam floor 5 at a position away from a column side by a specified dimension is opened in a rectangular form, and a cut-out piece 7 of the opened beam floor is erected toward the column side, to make a whitewash stopper for the beam floor 5, while providing an air fence, a mold lath, a metallic plate or other concrete stopper at a concrete placing joint. When placing concrete on the column side, the whitewash stopper prevents certain spreading of whitewash that has passed through a mesh of the lath material and whitewash flowing out from a gap between the concrete stopper and the beam floor 5 to the beam side. Whitewash that has flown over the whitewash stopper flows down from an opening 6, without spreading into the beam floor.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
