Abstract
A self-fastening threaded insert is described, with respect to a slab of building material, comprising a bearing element with respect to the slab, a deformation element adapted to interact with the slab, and a supporting element cooperating with the bearing element. The deformation element is deformed due to the effect of an external load transmitted by the supporting element, and is adapted to transmit to the slab forces which are perpendicular to an application force of the external load to be able to fasten the threaded insert to the slab. A process for assembling such threaded insert is also described.
Claims8
A self-fastening threaded insert adapted to be mounted with respect to a slab of building material, the threaded insert comprising:
- a bearing element;
- at least three spaced apart deformation elements adapted to interact with said slab, wherein each deformation element comprises an elastic toothed crown having teeth over the entire circumference of the crown, and is adapted to be housed with interference in a cylindrical recess of said slab, wherein teeth of adjacent crowns are offset from one another;
- a spacer ring connected to a respective deformation element;
- and
- a supporting element cooperating with said bearing element, wherein said at least one deformation element is deformed due to the effect of an external load transmitted by said supporting element, said at least one deformation element being adapted to transmit to said slab forces which are perpendicular to an application force of said external load to be able to fasten said threaded insert to said slab.
