Abstract
Injection mortar for anchoring a fastener containing a chemical composition that can cure in a curing process, and means for initiating the curing process characterized in that the chemical composition cures when irradiated with electromagnetic radiation, the means for initiating the curing process is formed by a radiation source for electromagnetic radiation, and the radiation source is placed within the anchoring zone.
Claims20
Injection mortar for fixing a fixing element in an injection mortar range in a bore hole comprising
- (a) a chemical composition adapted to cure in a curing process;
- and means for starting said curing process and wherein
- (b) said chemical composition cures upon exposure to electromagnetic radiation;
- (c) said means for starting said curing process is formed by a radiation source for electromagnetic radiation;
- (d) said radiation source is configured to be placed within said injection mortar range when inserted into said bore hole;
- and
- (e) wherein said radiation source comprises at least one light emitting diode which has contacts for a current supply and for a control outside said injection mortar range, and wherein
- (i) said at least one light emitting diode is arranged in said injection mortar range, and wherein said light emitting diode is configured to entirely or partly remain in said injection mortar range, or
- (ii) a sleeve is provided surrounding said at least one light emitting diode, wherein said sleeve is configured to entirely or partly remain in said injection mortar range and wherein said sleeve and said radiation source are configured to have said radiation source retractably inserted into said sleeve so said radiation source can be retracted from said sleeve when said sleeve remains in said injection mortar range.
Use of a reactive resin which is curable by exposure to UV radiation and of a radiation source as an injection mortar for fixing a fixing element, wherein said radiation source or a sleeve surrounding it, which is adapted to have said radiation source retractably inserted, remains entirely or partly in said injection mortar range, and wherein said radiation source is at least one light emitting diode or at least one optical fiber.
