Straight section of thick bamboo structure 20 one end is provided with the internal thread, has seted up the external screw thread in the reinforcing bar one end of butt joint, and sleeve structure's straight section of thick bamboo structure 20 one end can be established through the helicitic texture cover and fix on the reinforcing bar.

At one end of the trumpet structure 30, a latch 31 is provided to protrude outward along the inner wall of the sleeve. A space for inserting the bolt 31 is reserved between the bolt 31 and the inner wall of the other side of the sleeve. An arc surface 311 is arranged on one side of the bolt 31 close to the inner center of the sleeve. A spring 32 is fixedly arranged on the inner wall of the sleeve of the horn-shaped structure. The other end of the spring is connected with a connecting rod 33, and the other end of the connecting rod is fixedly connected with the central position of an arc-shaped disc 34. In the initial position, i.e. when the sleeves are not docked, the spring 32 is in a relaxed state. Since the spring has a certain strength, although the link and the arc plate have a certain self weight, the spring 32 has a strength enough to support the link and the arc plate. The arc-shaped disc 34 comprises an arc-shaped surface positioned on one side of the straight-tube structure 20 and a plane positioned on one side of the bolt. One end of the arc surface of the arc disc 34 is attached to the arc surface of the bolt 31, and when the arc disc is subjected to external force, the arc surface of the arc disc can move along the arc surface 311 of the bolt in an attaching manner. The arc-shaped discs on both sides of the connecting rod 33 are symmetrical in structure, and the radians of the arc-shaped surfaces are the same. In the present embodiment, the plug 31 has a hollow bent structure. With such a structure, the weight of the sleeve can be reduced.

When two sleeves are butted, two telescopic bolts are respectively positioned on one opposite side, two telescopic bolts are respectively inserted from the space of the horn-shaped structure port opposite to the telescopic bolts, in the inserting process, the inserted bolts are butted with the arc-shaped disc in the sleeve opposite to the inserted bolts, the arc-shaped disc is forced to rotate along the arc-shaped surface of the bolt in the same sleeve, the spring is in the inserting process from a loosening state to a stretching state, the bolt is continuously inserted, the arc-shaped disc rotates to a certain angle, the other end of the arc-shaped disc enters the arc-shaped surface of the inserted bolts, the butting force of the bolts is lost, then the arc-shaped disc returns under the action of spring force, the arc-shaped disc is positioned in a self-locking cavity formed between the two bolts, and two ends of the arc-shaped surface of the arc-shaped disc are respectively attached to the arc-shaped surfaces of the two opposite bolts. After the two sleeves are butted, the arc-shaped discs in the two sleeves are opposite and are simultaneously positioned in a self-locking cavity formed by the two bolts. Under the action of the self-locking cavity and the spring 32, the two sleeves can be prevented from being separated from each other.

When the column steel bar is constructed, the column steel bar cage is divided into an upper section and a lower section for construction, and external threads are respectively arranged at the ends of the upper section and the lower section of the steel bar, which need to be butted. After the binding of the lower section of the steel reinforcement cage of the column steel reinforcement cage is finished, the first sleeve 10 is sleeved on the upper end of each steel reinforcement one by one, and the bolt on the first sleeve 10 is adjusted to face the same direction.

Example 2

In this embodiment, the two sleeve structures are completely different. Including a first sleeve 40 and a second sleeve 50 that are insertably mated.

The first sleeve 40 includes one end 41 connected to the end of the column reinforcement and an abutting portion 42 that abuts the second sleeve. One end 41 connected with the column steel bar connecting end is of a straight cylinder structure, and the inner wall of the straight cylinder structure is provided with internal threads which can be in threaded connection with the column steel bar connecting end.

The abutting portion 42 is of a cylindrical structure having an outer diameter larger than that of the end 41 connected to the end of the column reinforcement. The end of the abutting portion 42 abutting the second sleeve 50 is provided with a trumpet-shaped structure. At least two locking mechanisms are uniformly arranged along the circumferential direction of the outer circumferential wall of the abutting part 42. Three latching mechanisms are typically employed. The locking mechanism comprises a limit groove 421 horizontally and fixedly arranged on the outer peripheral wall of the butt joint part 42, and a through hole is formed in the first sleeve wall provided with the limit groove 421. The bolt 422 is fixed on the limit groove 421 through the spring 423, and the limit groove 421 ensures that the bolt 422 extends and retracts linearly. When the spring 423 is in a relaxed state, the latch 422 passes through a through hole formed in the first sleeve wall, and partially extends into the hollow inner cavity of the first sleeve. An arc-shaped surface 4221 is arranged on the bolt 422, and the arc-shaped surface of the bolt in the first sleeve is opposite to one end of the butt joint of the first sleeve. In order to prevent the concrete from influencing the state of the spring when the column reinforced concrete is poured, the positioning groove is provided with a cover, the spring is completely sealed in the positioning groove, and the concrete is prevented from entering.

And the second sleeve 50 comprises one end 51 connected with the connecting end of the column steel bar and an abutting part 52 which is inserted and butted with the second sleeve. One end 51 connected with the column steel bar connecting end is of a straight cylinder structure, and the inner wall of the straight cylinder structure is provided with internal threads which can be in threaded connection with the column steel bar connecting end.

The abutting portion 52 is of a cylindrical structure having an outer diameter larger than that of the end 51 connected to the column-rebar connecting end. The outer diameter of the abutment portion 52 is the same as or slightly smaller than the inner diameter of the abutment portion 42 of the first sleeve 40. A limit hole 521 for the bolt to pass through is opened at a position of the abutting portion 52 opposite to the bolt.

When the second sleeve 50 is inserted into the first sleeve 40, the second sleeve 50 presses the arc-shaped surface of the latch 422, so that the latch 422 exits from the hollow inner cavity of the first sleeve 40, and at the moment, the spring 423 is in a compressed state; when the limiting hole of the second sleeve 50 is moved to the latch 422, the latch 422 loses the extrusion force, the latch 422 passes through the through hole of the first sleeve wall and the limiting hole 521 on the second sleeve 50 wall under the elastic force of the spring 423 to extend into the hollow inner cavity of the second sleeve 50, the second sleeve 50 is locked in the first sleeve 40, and at the moment, the second sleeve 50 also moves to the bottom in the butt joint part 42 of the first sleeve 40. The second sleeve 50 and the first sleeve 40 are conveniently aligned because the abutting end of the first sleeve 40 is of a trumpet-shaped structure.

For better locking connection effect, a ring of locking mechanisms may be respectively disposed on the outer circumferential surfaces of the abutting portions 42 of the first sleeve 40 near the two ends. The locking mechanism needs to be arranged in a staggered mode, and correspondingly, the limiting hole of the second sleeve 50 also needs to be arranged in a staggered mode. The purpose of the error setting is to ensure that the limiting hole that enters the first sleeve 40 first does not have a relationship with other locking mechanisms when the plug is inserted into the butt joint.

For better insertion and butt joint, the cross section of the limiting hole 521 of the second sleeve is set to be a horn-shaped structure, and the width of the large-diameter end of the horn-shaped structure is larger than that of the bolt. Referring to fig. 3, one end of the limiting hole contacting the first sleeve is a large diameter end. When the second sleeve is inserted into the first sleeve and the position is deviated, the lock tongues abut against the inclined plane at one side of the horn-shaped structure of the limiting hole under the action of spring force, and because at least two locking mechanisms are arranged, at least two lock tongues respectively abut against the inclined plane at one side of the horn-shaped structure of the limiting hole corresponding to the lock tongues; under the combined action of a plurality of springs and a plurality of lock tongues, one end of the first sleeve or the second sleeve connected with the column steel bar rotates, so that the lock tongues penetrate through the limiting holes to enter the hollow inner cavity of the second sleeve. Therefore, the cross section of the limiting hole is set to be of a horn-shaped structure, and when the maximum diameter of the limiting hole is larger than the diameter of the lock tongue, and the first sleeve and the second sleeve are butted, large allowable contraposition deviation exists.
