[0025] Reference below Figure 1-Figure 3 A positioning device 100 for a reinforcement cage according to an embodiment of the present invention is described.

[0026] According to the positioning device 100 for a steel cage according to the embodiment of the utility model, the positioning device 100 includes: a fixing frame 10 and a positioning rod 20 .

[0027] Among them, a through hole 11 is opened on the side of the fixed frame 10; at least two positioning rods 20 are respectively arranged on the opposite sides of the fixed frame 10, and the positioning rod 20 includes a positioning rod body 21 and a limiting plate 22. The positioning rod body 21 is suitable for passing through the through hole 11, and the limiting plate 22 is arranged at one end of the positioning rod body 21, and the limiting plate 22 can contact the outer surface of the steel cage.

[0028] Specifically, a through hole 11 is provided on the side of the fixed frame 10 for the positioning rod 20 to be inserted, and a limiting plate 22 is provided at one end of the positioning rod body 21 to limit the position of the steel cage. Before the steel cage is lowered, the positioning device 100 can be provided at the hole where the steel cage is to be lowered. During the lowering process of the steel cage, the positioning rod body 21 can be stretched through the through hole 11 so that the limiting plate 22 at one end of the positioning rod body 21 contacts the outer surface of the steel cage. Since at least two positioning rods 20 are respectively provided on two opposite sides of the fixed frame 10, the limiting plates 22 at the ends of the positioning rod body 21 that are relatively provided can contact the steel cage on two opposite sides, thereby constraining the position of the steel cage.

[0029] According to the positioning device 100 for the steel cage of the embodiment of the utility model, when the multi-section steel cage is lowered, the verticality and centering of the steel cage can be improved, thereby improving the positioning effect of the steel cage, accurately positioning and high construction efficiency.

[0030] It should be noted that there is no specific restriction on the shape of the fixed frame 10. For example, the fixed frame 10 can be a polygon composed of multiple side faces. Correspondingly, the number of positioning rod bodies 21 can also be increased according to the shape of the fixed frame 10. For example, when the fixed frame 10 is a quadrilateral, each side of the fixed frame 10 is provided with a through hole 11, and four positioning rod bodies 21 pass through a through hole 11 respectively. The positioning device 100 can limit the middle steel cage through four limiting plates 22, thereby improving the positioning efficiency of the positioning device 100.

[0031] like Figure 1-Figure 2 As shown, in some embodiments, the fixing frame 10 has a supporting rib 12 , and two ends of the supporting rib 12 are respectively connected to two adjacent side surfaces of the fixing frame 10 .

[0032] Specifically, during the lowering process of the steel cage, since the outer surface of the steel cage will contact the limit plate 22, the steel cage has a large weight and its shaking will cause the positioning device 100 to bear a large impact force. Support ribs 12 are set between the adjacent two sides of the fixed frame 10 to improve the structural stability of the fixed frame 10.

[0033] Therefore, the structural strength of the positioning device 100 can be improved while the positioning effect of the steel cage can be improved.

[0034] Preferably, both ends of the support rib 12 are respectively welded to the side surfaces of the fixing frame 10. By welding, the structural strength of the support rib 12 and the fixing frame 10 can be improved, thereby further improving the service life of the positioning device 100.

[0035] like Figure 3As shown, in some embodiments, the positioning rod 20 further includes a positioning pin 23 , and the positioning rod body 21 is provided with a plurality of positioning holes 211 along the length direction, and the positioning pin 23 is suitable for being inserted into the positioning hole 211 .

[0036] Specifically, a plurality of positioning holes 211 are provided along the length direction of the positioning rod body 21, so that the positioning pins 23 can be matched with the positioning holes 211. Before the steel cage is lowered, the length of the positioning rod body 21 extending into the fixing frame 10 can be adjusted to limit the position of steel cages of different specifications. After the length of the positioning rod body 21 is adjusted, the positioning pins 23 can be inserted into the positioning holes 211, so that the positioning pins 23 are inserted into the positioning holes 211 adjacent to the sides of the positioning rod body 21 and the fixing frame 10.

[0037] Therefore, through the cooperation between the positioning pin 23 and the positioning hole 211, the length of the positioning rod body 21 extending into the fixed frame 10 can be fixed. When multiple sections of steel cages are lowered, the multiple sections of steel cages can be ensured to maintain good centering and verticality, thereby improving the positioning quality of the steel cages.

[0038] It is understandable that when the positioning rod body 21 is limited by the positioning pin 23, the positioning pins 23 can be set in the positioning holes 211 on both sides of the positioning rod body 21 and the sides of the fixing frame 10. By setting the positioning pins 23 on both sides of the side of the fixing frame 10, the positioning rod body 21 can be prevented from moving during the lowering process of the steel cage, and the positioning quality of the steel cage can be further improved.

[0039] like Figure 3 As shown, the positioning rod 20 further includes a stopper 24, which is arranged at one end of the positioning rod body 21 away from the limiting plate 22. The projection area of ​​the stopper 24 is larger than the projection area of ​​the through hole 11.

[0040] Specifically, a stopper 24 is provided at one end of the positioning rod body 21 away from the limiting plate 22. At this time, a limiting plate 22 is provided at one end of the positioning rod body 21, and a stopper 24 is provided at the other end of the positioning rod body 21, which can prevent the positioning rod body 21 from escaping from the fixed frame 10 and improve the stability of the positioning device 100.

[0041] Further optionally, the stopper 24 is detachably connected to the positioning rod body 21. By arranging the stopper 24 and the positioning rod body 21 to be detachably connected, the assembly difficulty can be reduced while ensuring the structural strength of the positioning device 100, thereby improving the lowering efficiency of the steel cage.

[0042] In some embodiments, the positioning rod 20 further includes a handle 25, which is disposed on the side of the stopper 24 away from the positioning rod body 21. By arranging the handle 25 on the side of the stopper 24 away from the positioning rod body 21, the length of the positioning rod body 21 extending into the fixing frame 10 can be adjusted by pushing and pulling the handle 25 during the lowering process of the steel cage, thereby adapting to steel cages of different specifications and improving the positioning effect of the steel cage.

[0043] In some embodiments, the inner surface of the limiting plate 22 facing the steel cage is adapted to fit with the outer surface of the steel cage. Fitting the inner surface of the limiting plate 22 with the outer surface of the steel cage can reduce the space between the steel cage and the limiting plate 22, thereby improving the positioning effect of the limiting plate 22 on the steel cage.

[0044] Optionally, the limiting plate 22 is detachably connected to the positioning rod body 21. The limiting plate 22 and the positioning rod body 21 are detachably connected, which can reduce the difficulty of assembly while ensuring the structural strength of the positioning device 100, thereby improving the lowering efficiency of the steel cage. When the outer surface of the steel cage is of different shapes, the limiting plate 22 with a shape that adapts to the outer surface of the steel cage can be replaced, thereby improving the positioning effect of the positioning device 100 on the steel cage.
