Description

Technical Field

[0001] The utility model relates to the technical field of steel bar connection, in particular to a steel bar connection sleeve assembly. Background Art

[0002] In construction, the problem of connecting steel bars to each other is often encountered. Generally, welding is used to weld the ends of two adjacent steel bars together, but it is difficult to ensure the quality of the connection. Especially when working at high altitudes, the construction is limited by the space on the construction site, which makes the construction difficult, poses safety hazards, and causes great pollution to the environment. In recent years, a welding-free steel bar connection device has emerged. The device uses threaded connection to make threads on the ends of two adjacent steel bars and connects the two ends with nuts. The threaded connection method is complicated and requires special equipment on site to make threads on the ends of the steel bars. There are safety hazards in high-altitude operations. In addition, due to the long steel bars, connecting the threads is time-consuming and labor-intensive, with low production efficiency, and is not suitable for prefabricated construction methods.

[0003] CN 209163230U discloses a connecting piece group of a steel bar connection joint, and relates to the technical field of steel bar connection. A connecting piece group of a steel bar connection joint comprises a connecting piece group composed of several connecting pieces, the connecting piece group is shuttle-shaped in appearance, and the inside thereof is a smooth round hole; preferably, the number of connecting pieces is three. By squeezing the outer end faces of two cone sleeves matched with the connecting piece group, the connecting piece group is deformed and embedded between the cross ribs of the steel bar, and the cone sleeve and the connecting piece group are fixed by the inclined self-locking principle, so as to complete the connection of the steel bar. The connecting piece group has a simple structure, simple construction, good fastness and high construction efficiency. However, the installation environment of the steel bar after connection is relatively complicated. There is a situation of vibration in the process of rod-shaped, and there is a situation that the cone sleeve slips off the connecting piece, which on the one hand causes the separation of the connected steel bars and requires reconnection, reducing work efficiency, and on the other hand, there are safety hazards.

In order to increase the stability of the connection between the two steel bars and prevent the locking sleeves from loosening during use or installation, an anti-slip layer is provided on the fixing plate to increase the firmness of the connection between the locking sleeve and the fixing plate. At the same time, a locking block is provided on the locking sleeve. When the locking sleeve is sleeved on the fixing plate, the locking block contacts the locking plate, and the locking plate is deformed, so that the locking plate changes from a vertical state to a bent state, thereby increasing the stability of the connection between the locking sleeve and the fixing plate.

[0019] In order to more clearly illustrate the technical solution of the utility model, the utility model is further described below in conjunction with the accompanying drawings. Obviously, the accompanying drawings described below are only one embodiment of the utility model. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on this drawing and embodiment, which all belong to the protection scope of the utility model.

[0020] according to Figure 1-6 As shown, a steel bar connecting sleeve assembly includes two steel bars 1, and the adjacent ends of the two steel bars 1 are covered with at least two fixing plates 2. The outer walls of the two ends of the fixing plates 2 are provided with locking sleeves 3 for locking the fixing plates 2. The outer wall of the fixing plates 2 is provided with an anti-slip layer 4. The outer wall of the fixing plates 2 is also provided with a locking plate 5. The locking sleeve 3 is provided with a locking block 6. The locking block 6 contacts the locking plate 5, so that the locking plate 5 changes from an upright state to a bent state.

[0021] In the above specific embodiment, the connected ends of the two steel bars 1 are covered with at least two fixing plates 2. Preferably, there are two fixing plates 2 to facilitate the installation of the fixing plates 2. Both ends of the fixing plates 2 are fixed with locking sleeves 3. The locking sleeves 3 are sleeved on the outer walls of the two fixing plates 2. In order to increase the stability of the connection between the two steel bars 1 and prevent the locking sleeves 3 from loosening during use or installation, an anti-slip layer 4 is provided on the fixing plate 2 to increase the firmness of the connection between the locking sleeves 3 and the fixing plates 2. At the same time, a locking block 6 is provided on the locking sleeve 3. When the locking sleeve 3 is sleeved on the fixing plate 2, the locking block 6 contacts the locking plate 5, and the locking plate 5 is deformed, so that the locking plate 5 changes from a vertical state to a bent state, thereby increasing the stability of the connection between the locking sleeve 3 and the fixing plate 2.

[0022] The anti-slip layer is a triangular shaped protrusion.

[0023] An arc-shaped groove 61 is provided on one side of the locking block 6 close to the locking plate 5, and the connection point of the arc-shaped groove 61 is an inclined surface 62. In the process of sleeve-mounting the locking sleeve 3 on the fixing plate 2, the locking plate 5 first contacts the inclined surface 62 on the locking block 6. In the process of continuous advancement of the locking sleeve 3, the locking plate 5 is tilted and bent along the shape of the arc-shaped groove 61, thereby limiting the locking sleeve 3 and preventing the locking sleeve 3 from loosening during the installation and use of the steel bar 1, thereby increasing the safety of the connection. It is worth noting that the driving device used in the installation of the locking sleeve 3 is a hydraulic cylinder.

[0024] The surfaces of the two steel bars 1 are provided with transverse ribs. The fixing plate 2 is an arc-shaped structure, and its inner wall is provided with limiting teeth 7 that cooperate with the transverse ribs. Through the cooperation between the transverse ribs and the limiting teeth 7, the steel bars 1 are effectively fixed.

[0025] The locking sleeve 3 is a straight cylindrical structure, and the locking block 6 is located on the inner wall of the locking sleeve 3 near the rear end.

[0026] A limiting piece 8 is provided in the middle of the fixing piece 2 and respectively abuts against the two steel bars 1 . The limiting piece 8 is beneficial to the positioning of the steel bars 1 .
