SELF DRILLING MASONRY ANCHOR

摘要

A self drilling masonry anchor (10) or the like comprising at least one partially split outer tube (11) having first and second ends into which a partially threaded bolt (12) is substantially received therein with a thicker portion (13) of the bolt (12) protruding from the second end of the tube (11). A nut or screw means (15) with an internal thread corresponding to the thread on the bolt (12) is positioned adjacent and in use abutting against the first end of the tube (11) whereby the partially threaded bolt (12) is able to be screwed through or into the nut or screw means (15) to be drawn out of the tube (11). The thicker portion (13) of the bolt (12) has a drill tip (16) with a diameter at least as wide as the tube (11) with the drill tip (16) being used to drill into masonry, wood or like material whereby the tube (11) is inserted into the drilled hole during the drilling thereof. The bolt (12) is drawn out of the tube (11) by use of the nut or screw means (15) thereby drawing the thicker portion (13) into the tube (12) which results in the expansion in diameter of the split tube (11) thus being anchored in the hole.
