Description
Technical field
This utility model relates to a kind of building implement, is specifically related to a kind of mould broaching equipment.
Background technology
Rear anchoring, i.e. by related art method anchoring on existing concrete structure, is relative to casting concrete
Time the first anchoring (pre-buried) of pre-plugged and name, there is easy construction, use the advantage such as flexibly.Rich along with product category
Rich, the reduction of expense, construction technology universal, concrete post anchoring technology by the initial stage be only limitted to transformation, structural strengthening project by
Step is widely adopted in new construction.
Crab-bolt is the general name of all rear anchoring assemblies, is that connected piece anchors to the anchoring on the base materials such as concrete
Assembly.Larger difference is there is in crab-bolt by its operation principle and the difference of structure, anchoring property and the scope of application.
Expanding anchor bolt is the reaming by foot of hole concrete, the concrete inclined-plane formed after utilizing reaming and crab-bolt
Mechanical interlocked between expansion cone, it is achieved the anchoring to structural mount.It is high that expanding anchor bolt belongs to reliability in crab-bolt；Peace
The high-performance crab-bolt of Quan Xinggao.
The reaming of foot of hole concrete, in practice of construction, owing to not having reliable and practical reaming tool, result in expansion
The high-performance of pass crab-bolt cannot embody.Make expanding anchor bolt be transformed to friction-type mechanical anchor in engineering uses, give
Engineering project brings great potential safety hazard.
Utility model content
Technical problem to be solved in the utility model is owing to not having reliable and practical reaming tool, result in reaming type
The high-performance of crab-bolt cannot embody so that expanding anchor bolt is transformed to friction-type mechanical anchor, to engineering in engineering uses
