Description

Technical Field

[0001] This application relates to the technical field of engineering equipment, and particularly relates to a positioning device for the main reinforcement bars of the steel cage of a bored cast-in-place pile. Background Art

[0002] In projects involving the development of the upper cover of a subway parking lot, foundation treatment generally adopts a group pile combination mode for foundation reinforcement. Among them, cast-in-place piles are the most common reinforcement piles. A cast-in-place pile is a pile formed by positioning a hole and pouring concrete or reinforced concrete. The steel cage of the cast-in-place pile is the main supporting structure of the pile body. The main function of the steel cage is to improve the strength and compressive performance of the pile body. The steel cage is densely distributed inside the pile. By constraining the concrete, the overall strength and stability of the pile body are enhanced, greatly improving the bearing capacity of the cast-in-place pile so that it can withstand greater pressure and tension. When welding the steel cage of the cast-in-place pile, since the steel cage is cylindrical, the steel cage is prone to rolling during welding, resulting in irregular welding connections.

[0025] Among them, the outer positioning ring 1 is set as an annular plate and connected to the first support disk 4 through the first support bar 5, and the first support disk 4 is set as a round cake disk. Similarly, the annular connecting piece 10 is set as an annular plate and connected to the second support disk 11 through the second support bar 12, and the second support disk 11 is set as a round cake disk. Through holes are formed at both ends of the positioning card bar 7, and a plurality of positioning holes 8 are formed in the middle; one ends of a plurality of positioning card bars 7 are fixed on the outer positioning ring 1 through the first bolt 9, the other ends of the positioning card bars 7 are fixedly connected to the annular connecting piece 10 through the second bolt 13, and the first support disk 4 is connected to the second support disk 11.

[0026] In this way, the positioning card bar 7 is fastened by screws between the outer positioning ring 1 and the annular connecting piece 10 to form an annular chuck. When in use, after aligning two applications of the present application and aligning the steel bars one by one, the steel bars are inserted into the corresponding positioning holes 8 in the same way. In this way, the steel bars are positioned and supported by the chuck to form an overall stress structure. The positioning card bar 7 fixes and limits the positions of each steel bar of the steel cage.

At the same time, the annular connecting piece is set to have the same structure as the outer positioning ring 1. In this way, the nut 6 can be placed and adjusted in the stepped slot according to specific needs, so as to adapt to the production needs of steel cages with different numbers.

[0028] In one embodiment, in order to facilitate the alignment of both ends of the positioning card bar 7 or the adjustment for the production of steel cages with different numbers, the first support disk 4 and the second support disk 11 are detachably and fixedly connected.

[0029] In one embodiment, a structure for detachably and fixedly connecting the first support disk 4 and the second support disk 11 that is convenient for adjustment is that the second support disk 11 is detachably and fixedly connected to the first support disk 4 through bolts.

[0030] In one embodiment, another structure for detachably and fixedly connecting the first support disk 4 and the second support disk 11 that is convenient for adjustment is that a threaded hole is formed in the center of the second support disk 11, and a bolt column is formed in the middle of the first support disk 4, and the bolt column is threadedly connected in the threaded hole.

[0031] Finally, it should also be noted that in this text, relationships such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or apparatus comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or apparatus.
