Hole, according to《Concrete structure reinforcement design specification》The requirement of the 15th chapter embedding re-bar technique, Full threaded rod exist in GB50367-2013
When chemically-planted steel bar anchors, bore diameter at least needs big 4mm than Full threaded rod diameter, then with small brushes or small air pump by hole inner powder
Dirt is removed clean, is then put into chemical constitution glue in hole again, inserts Full threaded rod, reach after structure adhesive curing chemically-planted steel bar with
Concrete or the purpose of brick wall anchoring.
But existing chemically-planted steel bar technology, when in Full threaded rod implant bore, Full threaded rod often eccentric displacement, from
And the anchoring quality of Full threaded rod is impacted.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of chemically-planted steel bar component, pass through
The locating ring of setting can make it that Full threaded rod is preferably in middle position during chemically-planted steel bar.
To achieve the above object, the utility model provides following technical scheme：
A kind of chemically-planted steel bar component, including be plugged on the Full threaded rod on concrete component in drilling and be set in full spiral shell
On rasp bar and locating ring that outer ring surface abuts with drill hole inner wall.
By using above-mentioned technical proposal, pass through the Full threaded rod when being arranged the anchoring that locating ring enables on Full threaded rod
It is placed in the middle in the borehole, improve anchoring quality, by lifting anchoring quality, reduction anchorage length can be reached, save it is artificial and
The purpose of material expenditure, remarkable in economical benefits.
Preferably, excessive glue mouth is offered on the locating ring.
By using above-mentioned technical proposal, by opening up excessive glue mouth on locating ring, when being anchored, bonding can be made
Agent is flowed out from excessive glue mouth.
Preferably, the excessive glue mouth is included in the multiple overflows equidistantly opened up on locating ring external margin circumferencial direction
Groove.
By using above-mentioned technical proposal, pass through the overflow launder opened up outside locating ring so that locating ring and drilling side
The contact area of wall reduces so that it is smaller that force of sliding friction when both ends carry the Full threaded rod of locating ring is inserted during anchoring.
Preferably, the excessive glue mouth is included in the multiple overflows along the circumferential direction equidistantly opened up on the anchor ring of locating ring
Hole.
By using above-mentioned technical proposal, by the spout hole opened up on locating ring, slided on the outside of locating ring with drilling
Contact, bonding agent are extruded from spout hole.
Preferably, the excessive glue mouth is included in the relative twice deep-slotted chip breaker opened up on the anchor ring of locating ring.
By using above-mentioned technical proposal, by the deep-slotted chip breaker opened up, the area of excessive glue mouth is increased so that bonding agent is more
Easily overflow.
Preferably, the locating ring along the Full threaded rod it is axially arranged have it is multiple.
By using above-mentioned technical proposal, by setting multiple locating rings, the Full threaded rod upper and lower ends in anchor and position
All in center condition.
Preferably, the positioning ring thickness is 1.8-2.2mm.
By using above-mentioned technical proposal, the thickness setting of locating ring is relatively thin, and Full threaded rod chemically-planted steel bar is effectively anchored
Depth is almost without influence.
In summary, the utility model has the advantages that：
1st, by when being arranged the anchoring that locating ring enables on Full threaded rod Full threaded rod it is placed in the middle in the borehole, improve
Anchoring quality, by lifting anchoring quality, reduction anchorage length can be reached, save the purpose of artificial and material expenditure, it is economical
Remarkable benefit；
2nd, the overflow launder by being opened up outside locating ring so that the contact area of locating ring and borehole sidewall reduces, and makes
It is smaller that force of sliding friction when both ends carry the Full threaded rod of locating ring is inserted when must anchor；
3rd, by the deep-slotted chip breaker opened up, the area of excessive glue mouth is increased so that bonding agent is easier to overflow.
