<p><P>PROBLEM TO BE SOLVED: To support securely a slip form apparatus against a horizontal force applied to the slip form apparatus by a wind, a earthquake etc. by supporting with a concrete of an old material age rather than with a concrete of a young material age inside concrete forms. <P>SOLUTION: A slip form apparatus 10 is composed of a yoke 30, a pair of concrete forms 40, a support plate 50 which is installed beneath the concrete forms 40, a jack for a vertical displacement 60, a connection material 70 to connect the yoke 30 with the support plate 50, and a jack for a horizontal displacement 65 which displaces the support plate 50. When a massive horizontal force is applied, the slip form apparatus 10 is inclined and the support plate 50 abuts on a inner periphery of a concrete structure 1, having a old material age, i.e. expressing a high-strength, and supports the slip form apparatus 10. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
