Description
Technical field
It is a kind of plug-in type connecting sleeve the utility model relates to build the interfacing part of screw-thread steel.
Background technique
In technical field of building construction, screw-thread steel connection type is mainly overlapped by binding, be mechanically connected and welded three kinds,
In it is most commonly used be mechanical connection.Such as the publication number CN101624854A that Chinese patent literature is published, publication date in January, 2010
It is 13 days, entitled " a kind of reinforcement end reinforced large-diameter threaded connector and attaching method thereof " comprising screw rod, spiral shell
Set, the both ends of screw rod have outer straight thread respectively, are equipped with the interior straight thread to match with the outer straight thread on screw rod, screw rod in swivel nut
Outer straight thread be screwed on the interior straight thread of swivel nut.Its connection method is the identical spiral shell identical with rotation direction of diameter that is successively alternately screwed on
Bar, swivel nut, to complete steel reinforcement abutting joints.This kind of structures and methods are although feasible, but are primarily adapted for use in the docking of reinforcing bar level, for
When steel bar vertical docks, then since the length of vertical reinforcement is longer, the difficulty of centering is bigger, is not easy the operation that is screwed on.And after docking
The strength support of swivel nut is fully relied on, it is more demanding to swivel nut, once swivel nut is broken, it be easy to cause irreparable damage.
The for another example Authorization Notice No. CN2690477Y that Chinese patent literature is published, it is authorized announcement date on April 6th, 2005, real
It is " sleeve extruding and direct screw combined steel bar joint " with New Name, is made of half-thread formula sleeve and stud, half spiral shell
The front half section of line formula sleeve is inner screw sheath, and the second half section is extruded sleeve, is press-connected on steel bar end with its extruded sleeve, stud
Both ends be threaded in the inner screw sheath of two half-thread formula sleeves of docking respectively, to realize the docking of reinforcing bar.And
By the way that thread rotary orientation is arranged, it can also realize and directly screw the docking that stud realizes two half-thread formula sleeves, to facilitate reinforcing bar
Docking.Although this kind of structure is able to achieve the rapid abutting joint of reinforcing bar, but equally exist vertical reinforcement docking when, the more difficult assurance of centering,
It is not easy the operation that is screwed on, while only relying on the strength support of stud, it is clear that there are certain construction safety hidden danger.
For this purpose, needing to improve existing steel reinforcement abutting joints structure.
