Title:
コンクリート打ち分けの確認方法およびコンクリート構造物の構築方法
Document Type and Number:
Japanese Patent JP7187743
Kind Code:
B2
Abstract:
To propose a concrete placement confirmation method and a concrete structure construction method that can reasonably grasp the change point of the strength of the cast concrete when placing different types of concrete continuously in the height direction.SOLUTION: After placing a lower concrete 2 to a predetermined height, when placing an upper concrete 3 from below a concrete placing upper surface 1a of an existing placed concrete, by placing a sinking weight 71 that does not sink to either the lower concrete 2 or the upper concrete 3 but sinks to the other on the concrete placing upper surface 1a, it is confirmed whether the concrete facing the concrete placing upper surface 1a is switched from the lower concrete 2 to the upper concrete 3.SELECTED DRAWING: Figure 2
