Abstract
A powder-actuated mechanical lock concrete anchor, wherein the lower end portion of the concrete anchor is adapted to be disposed within the lower end portion of a blind bore drilled within a concrete substrate, and wherein a powder-actuated mechanical locking device is located within the lower end portion of the concrete anchor such that when the powder-actuated mechanism of the powder-actuated mechanical locking device is in fact actuated, either electrically or mechanically, the mechanical locking device will effectively be expanded radially outwardly so as to be lockingly engaged within lower side wall portions of the concrete substrate so as to in fact mechanically lock the concrete anchor within the blind bore drilled within the concrete substrate.
Claims17
An expansively-actuated mechanical lock anchor to be lockingly engaged within a bore defined within a structure, comprising:
- a solid rod anchor member defined around a longitudinally extending axis and adapted to be disposed within a bore pre-drilled within a structure into which said solid rod anchor member is to be fixedly secured;
- a housing, containing an expansively-actuated means, disposed within a lower end portion of said solid rod anchor member;
- mechanical locking means disposed upon said housing for moving outwardly from said housing and into engagement with side wall portions of the structure within which the pre-drilled bore is defined so as to lockingly engage said solid rod anchor member within the structure;
- and
- means for actuating said expansively-actuated means disposed within said lower end portion of said solid rod anchor member so as to cause said mechanical locking means to be moved outwardly from said housing and into engagement with the side wall portions of the structure within which the pre-drilled bore is defined so as to lockingly engage said solid rod anchor member within the structure.
