Description

Reinforcing bar self-locking connection structure
Technical field
The utility model is related to a kind of reinforcing bar self-locking connection structure, be mainly used for reinforcing bar and concrete bodies or reinforcing bar with Between reinforcing bar it is quick, be reliably connected, it can also be used to the connection between bolt and concrete bodies or bolt and bolt.
Background technology
Currently, the fields such as construction are frequently necessary to reinforcing bar being attached with concrete bodies, by reinforcing bar and reinforcing bar.Tradition Reinforcing bar and bar connecting, mainly have straight screw sleeve connection, welding, cold extrusion sleeve connection, grout sleeve connection etc..These Connection type is required to larger operating space and a large amount of manual operations, or even operator is needed to have certain professional skill Can, it is unfavorable for the raising of efficiency.And traditional reinforcing bar connect the mode of being mainly the following with concrete bodies:
One, it beats expansion bolt, punch inserting expansion bolt in concrete bodies, then weld reinforcing bar to be connected;
Two, bar planting, in concrete bodies internal drilling, with structure glue sticking anchor bar;
Three, built-in fitting, pre-embedded steel slab and anchor bar before casting concrete;
Four, embedded bar, the embedded bar before casting concrete.
The connection type of above-mentioned reinforcing bar and concrete bodies has their own advantages, and also suffers from certain drawbacks simultaneously, wherein playing expansion The switching performance of bolt is poor, is not suitable for long-term stress load;Bar planting then has that cost is high, destroys that big, durability is poor to original structure The problems such as;Built-in fitting occupied space is big, needs preservative treatment;Influence of the embedded bar then to construction formwork installation is big.Therefore, Shen Asking someone, exploration exploitation is a kind of to occupy little space, not to influence the reinforcing bar company that construction formwork is installed, easy to operate, stress weight bearing power is strong Binding structure.
Utility model content
The technical problem to be solved by the utility model is to provide one kind to occupy little space, easy to operate, stress load The strong reinforcing bar self-locking connection structure of ability.
The technical solution of the utility model is as follows:A kind of reinforcing bar self-locking connection structure, including steel bar end to be connected, Further include sleeve, the sleeve is spliced by least two circumferentially uniformly distributed sleeve blocks, and lantern ring is housed in bush outer sleeve;Institute It states sleeve upper end and is provided with vertical mounting hole, at least two installations side by side up and down are provided on the top of the inner wall of the hole installing Slot is respectively and fixedly provided with lock sheet groups in each mounting groove, and the lock sheet groups include at least three circumferentially uniformly distributed locking plates, in institute It states lock sheet groups outer hoop and is cased with spring ring, the outer shroud and spring ring of the lock sheet groups are caught in corresponding mounting groove, the locking plate The inner ring of group stretches out corresponding mounting groove, and the internal ring wall of each lock sheet groups is in up big and down small circular conical surface;In the reinforcing bar End machining has to be inserted into mounting hole with the one-to-one annular groove of lock sheet groups, the steel bar end until each locking plate from top to bottom Group is caught in corresponding annular groove, and the cell wall of the annular groove and the circular conical surface of lock sheet groups and bottom surface coincide.
Using the above structure, the sleeve that setting is spliced by least two sleeve blocks is being covered in bush outer sleeve encapsulation ring Cylinder upper end is provided with mounting hole, and mounting groove is arranged in inner wall of the hole installing, and lock sheet groups are clamped in mounting groove, and lock sheet groups will by spring ring Multiple locking plate cuffs form, and the inner ring of lock sheet groups is provided with up big and down small circular conical surface, in steel bar end insertion sleeve, steel bar end Be equipped with the one-to-one annular groove of lock sheet groups, steel bar end is limited in sleeve using the cooperation of lock sheet groups and annular groove, it is real Border in sleeve in use, first shape to sleeve lock sheet groups using lantern ring, then by lantern ring, sleeve, lock sheet groups Integral built-in is in concrete bodies, and the whole the space occupied in concrete bodies of lantern ring, sleeve, lock sheet groups is small, to concrete bodies Intensity effect is small;When needing to connect reinforcing bar, in steel bar end insertion sleeve, will directly connect single reinforcing bar only needs about 1~3 second Time, it is easy to operate, quick, do not need professional skill;Also, the cell wall of steel bar end annular groove and the circular conical surface of lock sheet groups and Bottom surface coincide, and improves the reliability and stability that sleeve is connect with steel bar end, stress weight bearing power is strong.It is particularly suitable for straight Reinforcing bar of the diameter no more than 20mm quickly connects, it can also be used to the quick connection of bolt.
Pad is equipped with compressed spring between the steel bar end and the interior bottom of mounting hole.Under the action of compressed spring, steel Muscle end is pushed against with lock sheet groups, can be effectively prevented between reinforcing bar and sleeve and axially be slid.
Structure glue or the special grouting material of concrete are filled in the mounting hole.When bar connecting or it is bolted When needing not only to bear pulling force but also bearing pressure, first injecting structure glue or concrete are special in mounting hole before steel bar end is inserted into With grouting material, steel bar end is inserted into, after structure glue or concrete special grouting material solidification, you can to steel bar end into Row is fixed.
The lower end of the steel bar end is in up big and down small cone., quickly insertion sleeve smooth convenient for steel bar end It is interior.
Annular groove is provided on the external annulus of the lock sheet groups, the spring ring is caught in annular groove.Convenient for being carried out to spring ring Positioning and limit avoid spring ring dislocation from influencing the locking function of lock sheet groups.
Preferably, the sleeve is made of two circumferentially uniformly distributed sleeve blocks, the mounting groove is on mounting hole top Under uniformly at intervals there are three, each lock sheet groups include circumferentially uniformly distributed six locking plates.
When the utility model is connect as reinforcing bar with concrete bodies, the lower end overstriking of the sleeve forms annular portion.Have Conducive to the reliability and stability connected between reinforcement sleeve and concrete bodies.
Further, horizontal reinforcing rib, the both ends of the reinforcing rib are fixed in the lower end of the sleeve annular portion Stretch out the outer shroud of annular portion.Be conducive to further strengthen the reliability and stability connected between sleeve and concrete bodies.
When the utility model is used as the connection between reinforcing bar and reinforcing bar, structure and the sleeve upper end of the sleeve lower end Structure mirror image.The structure of mirror image up and down is set in this way, can be used for connecting two reinforcing bars.
Advantageous effect:The utility model by sleeve block by being spliced into sleeve, in bush outer sleeve encapsulation ring, in sleeve upper end It is provided with mounting hole, lock sheet groups is clamped in inner wall of the hole installing setting mounting groove, is coordinated using the annular groove of lock sheet groups and steel bar end, it will Steel bar end and sleeve connection, to provide it is a kind of occupy little space, the reinforcing bar self-locking that easy to operate, stress weight bearing power is strong Tight connection structure.
