Abstract
There is provided a method for repairing or reinforcing a structure. The method includes the steps of: providing an adhesive sheet comprising an adhesive layer comprising at least a curable resin composition whose curing is promoted by irradiation with ionizing radiation and a curing aid which generates a basic substance by irradiation with ionizing radiation; attaching the adhesive sheet to a surface of the structure; and curing the adhesive layer of the adhesive sheet in a state where the adhesive layer is exposed.
Claims18
A method for repairing or reinforcing a structure by using an adhesive sheet comprising an adhesive layer, the method comprising the steps of:
- providing the adhesive layer comprising at least a curable resin composition whose curing is promoted by irradiation with ionizing radiation and a curing aid which generates a basic substance by irradiation with ionizing radiation;
- attaching the adhesive sheet to a surface of the structure;
- and
- curing the adhesive layer in a state where the adhesive layer is exposed.
(canceled)
A method for producing a structure repaired or reinforced by using an adhesive sheet comprising an adhesive layer, the method comprising the steps of:
- providing the adhesive layer comprising at least a curable resin composition whose curing is promoted by irradiation with ionizing radiation and a curing aid which generates a basic substance by irradiation with ionizing radiation;
- attaching the adhesive sheet to a surface of the structure;
- and
- curing the adhesive layer in a state where the adhesive layer is exposed.
A method for repairing or reinforcing a structure by using an adhesive sheet comprising an adhesive layer, the method comprising the steps of:
- applying a primer comprising an epoxy resin and a polyamine-based curing agent to a surface of the structure, to perform primer treatment;
- attaching the adhesive layer to the surface of the structure subjected to the primer treatment, the adhesive layer comprising at least a curable resin composition whose curing is promoted by irradiation with ionizing radiation and a curing aid which generates a basic substance by irradiation with ionizing radiation;
- and
- curing the adhesive layer.
(canceled)
A method for producing a structure repaired or reinforced using by an adhesive sheet comprising an adhesive layer, the method comprising the steps of:
- applying a primer comprising an epoxy resin and a polyamine-based curing agent to a surface of the structure, to perform primer treatment;
- attaching the adhesive layer to the surface of the structure subjected to the primer treatment, the adhesive layer comprising at least a curable resin composition whose curing is promoted by irradiation with ionizing radiation and a curing aid which generates a basic substance by irradiation with ionizing radiation;
- and
- curing the adhesive layer.
