Document Type and Number:
Japanese Patent JP2015200118
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a construction method of a concrete structure capable of securing a characteristic of a material adjacently installed in existing concrete, by reducing influence of cold heat of the existing concrete, when constructing the concrete structure by joining to the existing concrete.SOLUTION: An under surface of a concrete plate 2 for constituting a heater 1 is contacted with/placed on a surface of a vicinal range of a reverse surface of a joint surface with a new concrete structure 10 of existing concrete 8, and in a state of covering at least an upper surface of the concrete plate 2 with a heat insulation material 4, heat generated from a heater wire 3 buried in the concrete plate 2 is transmitted to the existing concrete 8 via the concrete plate 2, and the existing concrete 8 is put in a state of being heated to the predetermined temperature, and next, a grout material G is installed inside a built-in metal tube of a PC cable 12 attached to a coupler 9 buried in the existing concrete 8 and buried in the new concrete structure 10.
