Description

Technical Field

[0001] The utility model relates to the technical field of building steel bar connection, in particular to an adjustable steel bar sleeve for connecting steel bar parts. Background Art

[0002] At present, the steel bar connection in domestic civil construction mainly adopts the rib stripping and rolling straight thread technology. In nuclear power construction, it has been proposed to carry out industrialized, componentized and modularized construction of steel bars to shorten the civil construction period. The componentized and modularized construction of steel bars means that the steel bars are divided into different modules in advance in the steel bar processing plant, tied and fixed as a whole, and then transported to the site for connection. In this way, the time for tying steel bars on site can be saved. After the componentized steel bars are tied, the steel bars cannot move and rotate, and the steel bars that need to be connected often have a certain degree of misalignment. In addition, the componentized connection requires hundreds or even more steel bars to be connected at the same time, and the rib stripping and rolling straight thread technology cannot meet the needs of the industrialized, componentized and modularized construction of steel bars. Therefore, it is urgent to develop a new sleeve product to better meet the industrialized, componentized and modularized construction of steel bars. Utility Model Content

[0003] In order to overcome the above-mentioned defects existing in the prior art, the utility model provides an adjustable steel bar sleeve for connecting steel bar parts.

[0004] A steel bar adjustable sleeve for connecting steel bar parts comprises two steel bars, which are connected by a locking piece. The locking piece comprises a threaded sleeve connected to the ends of the two steel bars, and the two threaded sleeves are connected to a bidirectional screw.

[0005] Furthermore, the middle portion of the bidirectional screw is a screwing portion, and the screwing portion is prismatic.

[0006] Furthermore, the inner side walls at both ends of the threaded sleeve are provided with two spiral parts with the same rotation direction, and a partition is provided between the two spiral parts.

[0007] Furthermore, the end of the steel bar is provided with a thread that cooperates with the threaded sleeve.

[0008] Due to the adoption of the above technical scheme, the beneficial technical effect of the utility model is: when connecting steel bars in the utility model, the threaded sleeve is first installed on the steel bar so that the end of the steel bar is against the partition, and then the screwing part in the middle of the bidirectional screw is screwed. Since the threads at both ends of the threaded sleeve have the same screwing direction and the threaded connection between the threaded sleeve and the steel bar has been screwed to the very end, in the process of connecting the bidirectional screw and the threaded sleeve, the threaded sleeve no longer rotates, and the two threaded sleeves move in the direction close to the bidirectional screw at the same time, which makes the connection convenient.

[0013] 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.

[0014] according to Figure 1-3 As shown, an adjustable steel bar sleeve for connecting steel bar components includes two steel bars 1, and the two steel bars 1 are connected by a locking piece. The locking piece includes a threaded sleeve 2 connected to the ends of the two steel bars 1, and the two threaded sleeves 2 are connected to a bidirectional screw 3.

[0015] In the above specific technical scheme, two steel bars 1 are connected to the threaded sleeves 2 respectively, and the two threaded sleeves 2 are aligned and positioned by the bidirectional screw 3, thereby achieving the alignment of the steel bars 1, and the connection between the steel bars 1 is achieved by screwing the bidirectional screw 3, which is convenient.

[0016] The middle part of the bidirectional screw 3 is a screwing part 4, and the screwing part 4 is prism-shaped, which is convenient for the staff to use tools to rotate the threading screw.

[0017] Two sections of spiral parts 21 with the same rotation direction are provided on the inner side walls at both ends of the threaded sleeve 2, and a partition plate 22 is provided between the two sections of the spiral parts 21. When connecting the steel bar 1, the threaded sleeve 2 is first installed on the steel bar 1 so that the end of the steel bar 1 is against the partition plate 22, and then the screwing part 4 in the middle of the bidirectional screw 3 is screwed. Since the threads at both ends of the threaded sleeve 2 have the same rotation direction and the threaded connection between the threaded sleeve 2 and the steel bar 1 has been screwed to the very end, in the process of connecting the bidirectional screw 3 with the threaded sleeve 2, the threaded sleeve 2 no longer rotates, and the two threaded sleeves 2 move towards the direction of the bidirectional screw 3 at the same time, which is convenient for connection.

[0018] The end of the steel bar 1 is provided with a thread that matches the threaded sleeve 2 .
