摘要： PROBLEM TO BE SOLVED: To provide an anchor bolt and a method for correcting the deformation thereof in which the workability can be improved by making it easier to set the anchor bolt on a template. SOLUTION: The U-shaped anchor bolt includes a U-shaped bolt body 2 having left and right axial portions 2b, 2b which extend from both ends of a bottom portion 2a so as to be bent upwardly and in which a screw thread is formed on the outer periphery of each of the portions 2b, 2b and a steel band 3 which is mounted to both the axial portions 2b, 2b to connect both the portions so that the interval between the portions can be adjusted to a predetermined dimension. In this case, since the interval between the axial portions can be kept by the band 3 at a dimension specified at the time of fabrication, when the U-shaped anchor bolt 1 is set on a template 4 at a construction site, the portions 2b, 25 can be easily inserted into mount holes of the template 4.

摘要： PROBLEM TO BE SOLVED: To prevent the generation of cleavage to mortar and attain miniaturization by providing a reinforcing frame formed of steel material, at the peripheral edge part of mortar at the time of anchoring a steel column base with a column base hardware jointed to the lower end part of a steel column, onto foundation concrete through an anchor bolt, interposing mortar at the upper end face of the foundation concrete. SOLUTION: A steel column base 6 with a column base hardware 4 jointed to the lower end part of a steel column 5 is anchored onto foundation concrete 9 through an anchor bolt 1 embedded in the foundation concrete and a nut 9 screwed with the upper end part of the anchor bolt 1, interposing mortar at the upper end face of the foundation concrete 2. In this case, a reinforcing frame 11 formed of steel material is provided at the peripheral edge part of mortar 7. The reinforcing frame 11 is formed of a band steel plate of 6-9mm in thickness, for instance, jointed in endless shape, and installed on the foundation concrete 2 before the installation of the steel column base 6 so as to serve as a form at the time of filling mortar 7. A space W can thereby be made small, and column base structure can be miniaturized.

摘要： PROBLEM TO BE SOLVED: To increase shearing yield strength of a steel column base, prevent looseness of an anchor bolt and install the steel column base easily by filling grout into a clearance between the anchor bolt and a bolt hole from a grout filling hole having an opening at the side face of a column base hardware and communicated with the bolt hole. SOLUTION: A steel column base with a column base hardware 11 integrally jointed to the lower end part of a steel column is placed on foundation concrete 9. The upper end part of an anchor bolt 17 embedded in the foundation concrete 9 is inserted through a bolt hole 21 provided in the column base hardware 11, and fixed by a nut 16. A grout filling hole 22 communicated with the hole 21 is provided having an opening 23 at the side face of the column base hardware 11. Grout is filled from the grout filling hole 22 into a clearance between the anchor bolt 17 and the bolt hole 22. Part of the filled grout infiltrates into the nut 16 from a washer 15 and spurts out from the upper part of the nut 16, so that filling can be confirmed, and the anchor bolt 17 and the column base hardware 11 can be integrated.

摘要： PROBLEM TO BE SOLVED: To provide positioning construction capable of being easily removed from an anchor bolt, being done with less materials and using a template without requiring any large space in the case of conveyance or storage. SOLUTION: Two templates 12 formed in an L-shape are used to arrange then in symmetrical positions. Thereby, every through-hole is not required to be pulled out simultaneously from the upper end section 1a of every anchor bolt 1 like a conventional template formed of one sheet of plate member, and since through-holes 12a and 12b can be simultaneously pulled out from the upper end section 1a of some of anchor bolts 1 one by one of the L-shaped templates 12, the templates 12 can be easily removed in comparison with the conventional template formed of one sheet of plate member capable of being removed from the upper end section 1a of the anchor bolt 1.
