Description
Technical field
The present invention relates to a kind of anchor studs technical fields, and in particular to a kind of building wall spike devices convenient for firm installation.
Background technique
Intumescent anchor studs are to squeeze the anchor studs that anchor hole hole wall forms anchorage effect using expansion piece.Be using centrum with
Moving towards for expansion piece, promotes expansion piece to expand, and generates swelling agent pressure with hole wall concrete, and act on by shearing friction
It generates withdrawal resistance and realizes a kind of component anchored to connected piece.
Structure is complicated for current existing anchor studs, and installation is inconvenient, and anchor studs and anchoring casing pipe must match, and works as wall
When body hardness is higher, the expansion piece of anchoring casing pipe cannot achieve expansion, so that anchoring is loosely；In order to solve when wall hardness is higher
When, the expansion piece of anchoring casing pipe cannot achieve expansion issues, and existing anchor studs when in use, are matched on wall in advance to brill
The tail end in hole carries out reaming, then installs anchor studs again, since the size of reaming is difficult to be fitted close with the enlarged footing of anchor studs,
It is shaken after being installed so as to cause anchor studs.
