Technical Field

[0001] The utility model belongs to the technical field of steel bar connection, in particular to a hook-type tooling for steel bar connection. Background Art

[0002] In the field of construction engineering, steel bar connection is a routine process. Although traditional steel bar connection methods, such as welding and threaded connection, meet engineering needs to a certain extent, they also have some obvious shortcomings. For example, welding causes residual stress in the welding area of ​​the steel bar, which weakens the mechanical properties of the steel bar; threaded connection requires pre-processing of threads on the ends of the steel bar, which is cumbersome. In recent years, with the continuous advancement of construction technology, the requirements for steel bar connection have become higher and higher. Therefore, it is particularly important to develop a new, efficient and reliable steel bar connection method.

[0003] The existing patent with authorization announcement number: CN219528168U discloses a steel bar connection structure, in which an outer connecting pipe of the connection structure is sleeved on one of the steel bars, the inner diameter end of the outer connecting pipe faces outward, and the first semicircular pipe and the second semicircular pipe are symmetrically covered at the connection of the two steel bars to form an inner connecting pipe. The inner connecting pipe is quickly assembled by cooperating with the clamping plate and the clamping groove, and the outer connecting pipe is moved to the assembled inner connecting pipe, and the outer connecting pipe is rotated so that the inner wall of the outer connecting pipe is threadedly connected with the outer wall of the inner connecting pipe, so as to realize the rapid installation of the steel bar connection structure, and the first semicircular pipe and the second semicircular pipe of the inner connecting pipe are connected. The inner wall is provided with rib grooves matched with the ribs of the steel bar, so that the ribs on the outer wall of the steel bar are clamped with the rib grooves, thereby increasing the firmness of the steel bar connection structure connecting the steel bars, and by providing a groove in the middle of the inner wall of the first semicircular tube and the second semicircular tube, the length of the steel bar in the groove is adjusted to facilitate the clamping of the ribs of the steel bar with the rib grooves. This scheme is fixed by multiple sleeves, thereby increasing the manufacturing cost. At the same time, this scheme has low stability. At the same time, the existing steel bar connection method usually adopts a binding method, which makes the firmness low. In this regard, the utility model designs a hook-type tooling for steel bar connection to solve the above problems. Utility Model Content
