Description

Technical Field

[0001] The utility model relates to the technical field of steel bar connectors, in particular to a spliced ​​full-grouting sleeve with a connection and reinforcement structure. Background Art

[0002] The fully grouting sleeve is a common steel bar connector. When connecting the steel bars, fast-hardening, non-shrinkage grouting material is injected, and the steel bars and sleeves are connected by the bonding and biting effect between the materials. It has the advantages of reliable performance, wide applicability, and easy installation.

[0003] The common full-grouting sleeves currently on the market are mostly similar in structure. They are made of steel as the main body, with slurry inlet holes and slurry outlet holes welded on the sides. Two sets of steel bars are inserted from the openings at the upper and lower ends of the barrel respectively. After the insertion ports are closed, grouting is injected from the slurry inlet holes. There are some functional deficiencies in actual use, and there is room for improvement. For example, when the steel bars are inserted from the openings at the upper and lower ends of the barrel, there is basically no contact between the steel bars and the inner wall of the barrel. The steel bars are prone to small-angle skewness, and there is a certain probability that the upper and lower steel bars will deviate. There is a lack of reinforcement and guidance during the connection process, and it does not have the function of facilitating connection and reinforcement.

[0004] Now, a new type of spliced ​​full-grouting sleeve with a connection reinforcement structure is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a spliced ​​full-grouting sleeve with a connection and reinforcement structure to solve the problem of the lack of convenient connection and reinforcement functions proposed in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a spliced ​​full-grouting sleeve with a connection and reinforcement structure, comprising a steel sleeve, a slurry outlet hole welded on the top of one side of the steel sleeve, a slurry inlet hole welded on the bottom of one side of the steel sleeve, and fixing components are provided at the upper and lower ends of the steel sleeve to facilitate the connection and reinforcement of steel bars.

[0007] The fixing assembly includes two groups of external threaded rings, which are respectively fixedly connected to the upper and lower ends of the steel sleeve. A limiting ring is welded to one end of the external threaded ring near the steel sleeve. An internal threaded cap is sleeved on the outside of the external threaded ring. A steel bar insertion tube is vertically welded to one end of the internal threaded cap, and an elastic rubber ring is glued to the end of the steel bar insertion tube.

[0008] Preferably, the inner diameter of the internally threaded cap is adapted to the outer diameter of the externally threaded ring, and the threads inside the internally threaded cap are matched to the threads outside the externally threaded ring.

[0009] Preferably, one end of the limiting ring fits with one end of the internal thread cap, and the limiting ring and the internal thread cap are not connected.

[0010] Preferably, one end of the steel bar insertion tube passes through the interior of the internal thread cap, the internal thread cap, the steel bar insertion tube and the elastic rubber ring are connected, and the inner diameter of the elastic rubber ring is smaller than the inner diameter of the steel bar insertion tube.

[0011] Preferably, an internally threaded pipe seat is fixedly connected to the middle position of one side of the steel sleeve, an externally threaded steel shell is inserted into one side of the internally threaded pipe seat, a servo motor is installed on one side inside the externally threaded steel shell, an eccentric wheel is fixedly connected to the output end of the servo motor, a power cord is provided on one side of the externally threaded steel shell, and a USB plug is provided at the end of the power cord.

[0012] Preferably, the threads on the outside of the externally threaded steel shell match the threads on the inside of the internally threaded pipe seat, and the servo motor, power cord, and USB plug are electrically connected.

[0013] Preferably, steel support plates are welded to the upper and lower ends of the other side of the steel sleeve respectively, two groups of holding rods are vertically fixedly connected between one side of the two groups of steel support plates, and a side alignment groove is provided on the side of the steel support plate close to the steel sleeve.

[0014] Preferably, the steel support plates are symmetrically distributed about the horizontal center line of the steel sleeve, and the inner wall of the side alignment groove and the outer wall of the steel sleeve fit tightly, and the shapes of the two match.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the spliced ​​full-grouting sleeve with a connection reinforcement structure not only realizes the function of convenient connection and reinforcement, but also realizes the function of vibration and defoaming, and also realizes the function of easy gripping and adjustment;

[0016] (1) By providing an external threaded ring, a limiting ring, an internal threaded cap, a steel bar insertion tube and an elastic rubber ring, when in use, the upper and lower groups of steel bars are respectively inserted from the upper and lower ends of the steel sleeve. As the steel bars are in place, the fast-hardening non-shrinkage grouting material is injected along the slurry inlet hole. As the interior of the steel sleeve is filled with slurry, the overflowing slurry is discharged from the slurry outlet hole. When the slurry solidifies, the upper and lower groups of steel bars are connected. Before inserting the steel bars, an internal threaded cap with a steel bar insertion tube of corresponding size is selected according to the size of the steel bars. The internal threaded cap is inserted along the external threaded ring and tightened until its bottom is pressed against the limiting ring. The steel bars are inserted along the opening of the steel bar insertion tube at the top of the internal threaded cap, and enter the steel sleeve through the steel bar insertion tube and the elastic rubber ring. The steel bar insertion tube fits the outer wall of the steel bar to keep it upright and stable. The upper and lower groups of steel bars are in a vertical line. The elastic rubber ring fits the surface of the steel bar to prevent the slurry from overflowing along the internal gap of the steel bar insertion tube, thereby achieving the function of convenient connection and reinforcement.

[0017] (2) By providing an internal threaded pipe seat, an external threaded steel shell, a servo motor, an eccentric wheel, a power cord and a USB plug, when in use, the fast-hardening non-shrinkage grouting material is injected along the slurry inlet hole. Before injecting the slurry, the external threaded steel shell is inserted along the internal threaded pipe seat and tightened. Then the USB plug is inserted into the power supply, and the servo motor is continuously powered through the power cord. The servo motor drives the eccentric wheel to rotate at high speed to generate vibration. As the slurry is injected, the fine and high-frequency vibration can make the bubbles in the slurry float up and break quickly, reduce the pores inside the slurry, and make the overall structure more compact. After the grouting is completed, the external threaded steel shell is loosened and removed to facilitate subsequent recycling, thereby realizing the function of vibration defoaming.

[0018] (3) By providing a steel support plate, a gripping rod and a side alignment groove, when inserting the steel bars up and down for docking, the operator can hold the gripping rod to adjust it up and down. Alternatively, the gripping rod and the horizontal steel bars can be bundled and reinforced. When placed horizontally, one side of the steel support plate with the side alignment groove touches the ground to form a support to prevent the cylinder body from tilting and sliding, thereby realizing the function of easy grasping and adjustment.

[0034] Working principle: When the present invention is in use, first, the upper and lower groups of steel bars are respectively inserted from the upper and lower ends of the steel sleeve 1. As the steel bars are in place, the quick-hardening non-shrinkage grouting material is injected along the slurry inlet hole 14. As the interior of the steel sleeve 1 is filled with slurry, the overflowing slurry is discharged from the slurry outlet hole 7. After the slurry solidifies, the docking of the upper and lower groups of steel bars is completed. Before inserting the steel bars, the internal threaded cap 4 with the corresponding size of the steel bar insertion tube 5 is selected according to the size of the steel bar. The internal threaded cap 4 is inserted and tightened along the external threaded ring 2 until its bottom is against the limit ring 3. The steel bar is inserted along the opening of the steel bar insertion tube 5 at the top of the internal threaded cap 4, and enters the steel sleeve 1 through the steel bar insertion tube 5 and the elastic rubber ring 6.
