Template and method for manufacturing the template

Abstract

We provide templates that are compact and easy to transport. [Solution] The present invention comprises a plate-shaped template body 10, a cylindrical member 1 that penetrates the template body 10 in the thickness direction, and a long nut 2 whose upper end is inserted into the cylindrical member 1. The long nut 2 has a small diameter portion provided on the upper end, a large diameter portion provided on the lower end that is continuous with the small diameter portion, a stepped portion connecting the small diameter portion and the large diameter portion, and a female screw hole that penetrates axially along its entire length. The outer diameter of the small diameter portion inserted inside the cylindrical member 1 is approximately the same as the inner diameter of the cylindrical member 1, and the outer diameter of the large diameter portion is larger than that of the small diameter portion.

Claims

1. A template used for positioning bolts for mounting seismic isolation members in seismically isolated buildings, and anchor bolts for buildings, A flat template body, A cylindrical member that penetrates the template body with the thickness direction of the template body as the axial direction, A long nut whose upper end is inserted into the cylindrical member and Equipped with, The template is characterized by having a long nut, which is provided on the upper end side and has an outer diameter substantially the same as the inner diameter of the cylindrical member and is inserted into the inside of the cylindrical member; a large diameter portion provided on the lower end side that is continuous with the small diameter portion and has an outer diameter larger than the small diameter portion; a stepped portion that connects the outer surface of the small diameter portion and the outer surface of the large diameter portion; and a female screw hole that penetrates axially along its entire length.

2. The template body is made of precast concrete or precast mortar. The concrete template according to claim 1, wherein the cylindrical member has a flange or grooves extending in the outer direction on its outer surface.

3. The template according to claim 1, wherein the cylindrical member is formed with a tapered inner surface that becomes larger in diameter towards the bottom, and the long nut is provided with a tapered outer surface that becomes larger in diameter towards the bottom, matching the inner surface of the cylindrical member.

4. A method for manufacturing a template according to claim 2, A method for manufacturing a template, comprising: a cylindrical member placement step of placing the cylindrical member on the bottom surface of a flat box-shaped formwork formed from a bottom surface that opens upward and is horizontal, and side walls surrounding the bottom surface, with the axial direction being vertical; a long nut erection step of erecting the long nut by inserting the small diameter portion of the long nut into the inside of the cylindrical member from above; a positioning step of positioning the long nut with a precast template to position the cylindrical member within the formwork; and a pouring step of pouring concrete or mortar into the formwork to the extent that the lower end face of the cylindrical member is not buried, with the long nut fixed with the precast template.
