Description
Technical field
The present invention relates to anchor plate technical field, and in particular to one kind is used for Bar Anchorage plate fast fixing tool and its made
Use method.
Background technology
The anchor plate of reinforcing bar is a basic fundamental in concrete structure engineering, is all types of industries and civil buildings, big
In an important technology in the concrete structure engineering design and construction such as bridge beam, hydro-structure, subway, tunnel, nuclear power station
Hold.Reinforcing steel bar machinery anchorage technology provides a kind of brand-new mechanism anchorage method for the Bar Anchorage in concrete structure, by spiral shell
Cap is connected through a screw thread mode and the end reinforced anchor plate for being connected to form reinforcing bar with the anchor plate that backing plate is combined into one.It is acted on
Mechanism is：The anchor force of reinforcing bar is held jointly by the cohesive force between reinforcing bar and concrete and the Local bearing capacity of anchor plate to be carried or entirely
Portion is undertaken by anchor plate.This refers to art and compares traditional reinforcing steel bar machinery anchorage technology, and Bar Anchorage plate is applied in concrete structure,
Can reduce anchorage length of steel bar 40% again on, save anchor bar more than 40%；Bar Anchorage plate is applied in frame joint, can
Anchoring steel more than 60% are saved, anchor plate is connected through a screw thread with end reinforced.Anchor plate has anchoring rigidity big, anchors
The advantages that performance is good, convenient construction, is advantageous to commercialized supply.
End reinforced anchor plate is by manually screwing at present, for the connection tightness of anchor plate and reinforcing bar
Be by artificial judgment, some is only to tighten by hand, some be then after first tightening by hand again by corresponding spanner again
Tighten.The connection tightness of anchor plate and reinforcing bar has very big influence to the quality of the section concrete structure.
In place of the mounting means Shortcomings of above anchor plate, one, manually install, not only installation rate is slow, efficiency
It is low, and very waste of manpower, it is the rational Distribution utilization of progress to labour.2nd, artificial judgment anchor plate and reinforcing bar are passed through
Connection jail in very big human error, as human physical power is constantly slowly consumed, its judgement significantly by
Influence, Gu manually judge that the connection jail of anchor plate and reinforcing bar is inaccurate.3rd, workmen can have necessarily lazy at work
Property, however not excluded that the situation of half-hearted work, it is possible to simply anchor plate is screwed on reinforcing bar and not fastened, is severely impacted
The quality of concrete structure, it is unfavorable for improving construction quality.
The content of the invention
For in the prior art the defects of, the present invention provide one kind is used for Bar Anchorage plate fast fixing tool and its use
Method, to reduce time and the labour required for installation anchor plate, operating efficiency is improved, while be also correspondingly improved installation matter
The quality of amount and engineering.
The invention provides one kind to be used for Bar Anchorage plate fast fixing tool, including power delivery section, flexible axle and hand
Hold part；The portion of the handle is connected by the flexible axle and the power delivery section；The portion of the handle includes outer
