PURPOSE:To install a foundation bolt so as to be very difficult to pull-off without much labor required for installation, by a method wherein a hollow structure having eneven inner and outer surfaces is located, concrete is placed, the foundation bolt is inserted into the hollow structure to integrally form them by means of a curing material. CONSTITUTION:A setting and installing structure for a foundation bolt 33 is cylindrical, and forms a continuous surface formed with a projection 21 and a recess 22, and the under surface is closed with a bottom plate 25. Thereafter, a cover 27, attached thereto, is temporarily placed in the set position of the foundation bolt 33, and after reinforcing bars are arranged, concrete 35 is placed. The foundation bolt 33 is attached to a foundation panel 6 to insert it into the setting and installing structure, mortar 8 is poured up to the surface of the foundation panel 6, and a part of the mortar 8 is also poured in the setting installing structure. This enables installation of the foundation bolt having a high resistance force against pull-off without needing much labor. |
