CONCRETE FLOOR SURFACE CONSTRUCTION TOOL AND CONCRETE FLOOR SURFACE CONSTRUCTION METHOD
To provide a concrete floor construction method that can simplify the joint work and significantly reduce the labor and time required for the joint work in the concrete floor construction.SOLUTION: A vertical trowel plate portion 42 of a floor surface construction tool 40 is inserted into a step portion S, an inner side surface 42b thereof is brought into contact with an outer surface F3 of a concrete layer F, and a lower surface 41b of a horizontal trowel plate portion 41 is brought into contact with a surface F1 of the concrete layer F. In this state, when an operator grasps a handle member 44 by hand and moves the floor surface construction tool 40 horizontally along a retaining frame 100 in the longitudinal direction (arrow line X direction) of the step portion (step-like gap) S, by passing the floor surface construction tool 40, a convex curved surface (R surface) F4 is formed along the longitudinal direction of a peripheral edge portion F2 of the surface F1 of the concrete layer F facing the concrete retaining frame 100.SELECTED DRAWING: Figure 5
【課題】コンクリート床面工事において、打継作業を簡易化し、打継作業に要する労力と時間を大幅に削減することができるコンクリート床面施工法などを提供する。【解決手段】床面施工具４０の垂直鏝板部４２を段差部Ｓに挿入し、その内側面４２ｂをコンクリート層Ｆの外側面Ｆ３に当接させるとともに水平鏝板部４１の下面４１ｂをコンクリート層Ｆの表面Ｆ１に当接させた状態とし、この状態で、作業者が柄部材４４を手で把持して、床面施工具４０を止め枠１００に沿って段差部（段差状隙間）Ｓの長手方向（矢線Ｘ方向）に水平移動させると、床面施工具４０の通過により、コンクリート止め枠１００と対向するコンクリート層Ｆの表面Ｆ１の周縁部Ｆ２の長手方向に沿って凸曲面（Ｒ面）Ｆ４が形成される。【選択図】図５
