Abstract

PURPOSE:To exactly pack a filling material into a foundation as well as raise the accuracy of the level regulation by using a vertically mavable anchor bolt with thread, a level-adjustable formwork, and a filling material, e.g., cement mortar, etc. CONSTITUTION:A vertically movable anchor bolt 1 with thread is placed at the top end of a concrete foundation 2, and its top level is set up to a given one. Then, a formwork 3 with a screw 4 for regulating its vertical movement is set on the top end of the concrete foundation 2, the top end is leveled with the anchor bolt 1 by the screw 4, and a filling material 5 of cement mortar, etc., is packed. After the filling material 5 is hardened to a given strength, the bottom plate 8 of a pillar 9 is fixed to the upside of the filling material 5, a formwork 7 is set around the concrete foundation, and then a filling material 6 of cement mortar, etc., is packed under pressure.

べるような問題点が指摘されていた。[Detailed description of the invention] Conventionally, when installing columns and machines, the height is adjusted using liners (steel plates) or wedges, and then hard cement mortar (or non-shrinkable mortar) is applied. A construction method in which the gap between the base plate and the foundation concrete was filled with rods or other tools was generally adopted, but the following problems were pointed out.

■　ライナー（鋼板）とクサビ等による高さの調整は作
業能率が悪くしかも高精度が期待出来ない。■ Height adjustment using liners (steel plates) and wedges is inefficient and high precision cannot be expected.

浸透を招きやすい） ■　雨水の浸透による錆によってライナー（鋼板）が減
肉した場合、上部荷重の載荷がライナー（鋼板）に期待
出来なくなり詰めモルタル部分への過大荷重となる。■ Since a liner (steel plate) and wedge are used, it will be a hindrance when filling with mortar later, and the mortar will not be filled completely uniformly, which may result in voids in some areas (easily inviting rainwater to seep in). If the liner (steel plate) becomes thinner due to rust caused by rainwater penetration, the liner (steel plate) cannot be expected to carry the upper load, resulting in an excessive load on the filling mortar section.

■　ライナー（鋼板）と詰めモルタルは異質である為に
完全に一体化せず上部荷重及び機械等の繰り返し荷重等
に対しては弱点となる。■ Because the liner (steel plate) and filling mortar are different, they are not completely integrated, making them vulnerable to upper loads and repeated loads from machinery, etc.
