An expansion bolt and a slip-proof expansion sleeve thereof.
The invention relates to an expansion bolt (10) for anchoring in a cylindrical borehole (40).
Disclosed are a scissor-type expansion bolt and the use thereof.
It is installed by use of foam glue and expansion bolt.
The anchor comprises a mounting plate (2) to one side of which there is secured an expansion bolt (1) and on the other side of which there is provided a quick-release operating lever (3) for the bolt.
The expansion bolt (10) expands further if the borehole (40) expands, for example as a result of cracking.
The expansion bolt (10) is anchored in the borehole (40) by the axial displacement of the expansion sleeve (14) on the expansion section (22).
According to the invention, the expansion bolt (10) is configured with a tubular bolt base part (12) to which a hollow conical expansion section (22) is moulded by forming.
