Title:
アンカー埋め込み用孔の構造および溝形成装置
Document Type and Number:
Japanese Patent JP7077211
Kind Code:
B2
Abstract:
To provide a hole structure that can resolve filling defects for holes for embedding anchors that are drilled horizontally, and a device that can realize the structure.SOLUTION: The present invention is provided with a guide part that limits the movement of a rod 20 so that a drill blade 30 of a drill part contacts only the lower half section of a hole, and a groove Z is formed only at the lower half section of the hole inner peripheral surface. A filling material easily flows into the groove Z that is formed only at the lower half section of the hole, and this prevents filling defects for the filling material.SELECTED DRAWING: Figure 3
