Conical thread quick locking type self-adapting variable diameter reinforcing steel sleeve

Abstract

This utility model discloses a tapered thread quick-locking adaptive variable diameter rebar sleeve, which relates to the field of rebar connection technology. The tapered thread quick-locking adaptive variable diameter rebar sleeve includes a rebar, and the outer wall of the rebar is provided with a connecting mechanism and a reinforcing mechanism. The reinforcing mechanism is located outside the connecting mechanism. The connecting mechanism includes two compression sleeves and a connecting sleeve. The reinforcing mechanism includes a reinforcing part and a fixing part. The reinforcing part includes two fixing rings, two sets of insert blocks, and two compression rings. The technical effect is that the two sets of springs and two sets of dampers in the reinforcing mechanism compress the compression rings, causing them to push the insert blocks into the inner side of the connecting sleeve. The compression rings are then fixed by the screw and nut, thereby fixing the insert blocks and effectively preventing the compression sleeves from loosening or falling off the outer wall of the connecting sleeve, enhancing connection stability. Simultaneously, the corrugated tube outside the springs protects the springs from external corrosion and damage, extending their service life.

Description

Technical Field

[0001] This utility model relates to the field of rebar connection technology, specifically a tapered thread quick-locking adaptive variable diameter rebar sleeve. Background Technology

[0002] In the field of construction engineering, steel reinforcement connections are a core component ensuring structural safety and stability, and the reliability and efficiency of the technology are of paramount importance. With the continuous advancement of the construction industry, increasingly stringent requirements have been placed on the quality, efficiency, and adaptability of steel reinforcement connections.

[0003] Axial cold-press connection of reinforcing bars is a mechanical connection method that uses a cold extrusion press to deform the connecting sleeve, thereby combining the sleeve with the two reinforcing bars inserted into it. Through extrusion, the sleeve undergoes plastic deformation, tightly gripping the transverse and longitudinal ribs of the reinforcing bars, thereby realizing the transfer of force between the two reinforcing bars.

[0004] When connecting steel bars, the existing connecting sleeves simply have the outer compression sleeve fitted on the outside. During long-term use, the compression sleeve may loosen due to external environmental factors such as vibration or impact, thus affecting the stability of the steel bar connection. Therefore, a tapered thread quick-locking adaptive variable diameter steel bar sleeve is proposed. Utility Model Content

The outer walls of the two reinforcing bars 1 are in contact with the inner side of the connecting sleeve 21. The outer walls of the connecting sleeves 21 are in an interference fit with the inner sides of the two extrusion sleeves 22, respectively. The sides of the two sets of inserts 33 near the two fixing rings 31 slide sequentially through the outer walls of the two fixing rings 31 and the outer walls of the connecting sleeves 21, extending into the interior of the connecting sleeves 21. The outer walls of the two fixing rings 31 are in a sliding connection with the inner sides of the two extrusion rings 32, respectively. The outer walls of the two sets of inserts 33 are fixedly provided with two sets of arc-shaped blocks 34, respectively. The outer walls of the two sets of arc-shaped blocks 34 are in contact with the inner sides of the two extrusion rings 32, respectively. The sides of the two extrusion rings 32 far apart are fixedly provided with two sets of springs 37 and two sets of dampers 36, respectively. The sides of the two sets of dampers 36 and two sets of springs 37 far apart are fixed to the sides of the two extrusion sleeves 22, respectively. The connection is as follows: two sets of springs 37 are respectively fitted with two sets of bellows 35 on their outer walls. The side of the two sets of bellows 35 that are close to each other is fixedly connected to the outer walls of the two extrusion rings 32, and the side of the two sets of bellows 35 that are far from each other is fixedly connected to the outer walls of the two extrusion sleeves 22. The outer walls of the two fixed rings 31 are respectively fixedly connected to the outer walls of the two fixed frames 39. Two fixed plates 310 are respectively fixedly installed on the outer walls of the two extrusion rings 32. The side of the two screws 38 that is close to the two fixed plates 310 extends through the outer walls of the two fixed plates 310 to the inner side of the two fixed frames 39. Two nuts 311 are respectively better installed on the outer walls of the two fixed plates 310.

After the fitting is completed, the two extrusion sleeves 22 are extruded by a cold extrusion machine, so that the connecting sleeve 21 and the outer wall of the two steel bars 1 are engaged.

After the insertion is completed, the two screws 38 are manually tightened. After the two screws 38 are tightened, the compression rings 32 can be fixed.
