[0031] The following combines the attachedFigure 1-2 A further detailed description is given to a steel bar positioning device for the pier shaft of the present application.

[0032] A steel bar positioning device for the pier shaft, the steel bar positioning device includes a horizontally arranged first positioning frame 1 and a second positioning frame 2, and the first positioning frame 1 and the second positioning frame 2 are connected up and down through a connecting frame;

[0033] The connecting frame includes a first connecting rod 6 and a second connecting rod 7 arranged in an X-shaped cross; the upper end of the first connecting rod 6 is rotatably connected to one side of the first positioning frame 1, and the lower end of the first connecting rod 6 is rotatably connected to the other side of the second positioning frame 2; the upper end of the second connecting rod 7 is detachably fixed to the other side of the first positioning frame 1, and the lower end of the second connecting rod 7 is detachably fixed to one side of the second positioning frame 2;

[0034] The first connecting rod 6 is rotatably connected to the first connecting rod 6 at the intersection.

[0035] In a specific embodiment of the present application, both the first positioning frame 1 and the second positioning frame 2 include a rectangular frame 10 and two arc ends 11, and the two arc ends 11 are respectively fixedly arranged at both ends of the rectangular frame 10, wherein the curvature of the arc ends 11 is preset in advance according to the shape of the pier shaft. During use, by presetting the first positioning frame 1 and the second positioning frame 2 inside the steel bars, the positioning of the longitudinal position and distribution state of the steel bars is realized, and thus the control of the concrete cover thickness is realized. As shown in the attached Figure 2 The first connecting rod 6 and the second connecting rod 7 arranged in an X-shaped cross are rotatably connected in a vertical plane. Among them, the upper end of the first connecting rod 6 is rotatably connected to the right side of the first positioning frame 1 (with the right side of the first positioning frame 1 as the rotation axis), and the lower end of the first connecting rod 6 is rotatably connected to the left side of the second positioning frame 2 (with the left side of the second positioning frame 2 as the rotation axis). The upper end of the second connecting rod 7 abuts against the left side of the first positioning frame 1 through the top notch, and the lower end of the second connecting rod 7 abuts against the right side of the second positioning frame 2 through the bottom notch. During use, along the direction away from the second connecting rod 7, rotate the first positioning frame 1 and the second positioning frame 2 to release their fixed connection with the second connecting rod 7. With the relative rotation between the first connecting rod 6 and the second connecting rod 7, the steel bar positioning device can be deformed to an overall approximately planar structure. On the one hand, it is convenient for transportation and handling. On the other hand, through the rotational cooperation between the first connecting rod 6 and the second connecting rod 7 and the rotational cooperation between the first connecting rod 6 and the first positioning frame 1 and the second positioning frame 2, after the steel bar construction is completed, the steel bar positioning device can be lifted to realize rapid release from the pier shaft steel bar cage, which is convenient for subsequent secondary utilization.

[0036] A plurality of connecting frames are arranged at intervals along the axial directions of the first positioning frame 1 and the second positioning frame 2.

[0037] In a specific embodiment of the present application, four connecting frames are arranged at intervals along the axial directions of the first positioning frame 1 and the second positioning frame 2 to enhance the overall structural stability of the steel bar positioning device.

[0038] To improve the structural stability of the first positioning frame 1 and the second positioning frame 2 during use and prevent deformation under pressure, reinforcing bars are fixedly arranged inside the first positioning frame 1 and the second positioning frame 2.

[0039] The reinforcing bars include a transverse reinforcing bar 3 and a longitudinal reinforcing bar 4 that are cross - arranged inside the first positioning frame 1 and the second positioning frame 2.

[0041] The reinforcing bars further include radial reinforcing bars 5 arranged at the arc ends 11 of the first positioning frame 1 and the second positioning frame 2.

[0042] In a specific embodiment of the present application, four radial reinforcing bars 5 are evenly and spacedly arranged inside the arc ends 11 at both ends of the first positioning frame 1 and the second positioning frame 2 respectively.

[0043] The second connecting rod 7 is telescopically arranged along its own axial direction.

[0044] In a specific embodiment of the present application, the second connecting rod 7 is specifically a telescopic rod structure, which can maintain a fixed length in any telescopic state. This is prior art and will not be elaborated here. During use, by telescopically adjusting the length of the second connecting rod 7 and cooperating with the rotational connection of the first connecting rod 6 with the first positioning frame 1 and the second positioning frame 2, the adjustment of the inclined state of the steel bar positioning device can be realized, so as to match the pier shaft designs in different inclined states.

[0045] The steel bar positioning device further includes a horizontally arranged third positioning frame 9, and the third positioning frame 9 is rotatably arranged along the axial direction at the intersection of the first connecting rod 6 and the second connecting rod 7;

[0046] The third positioning frame 9 is connected to the first positioning frame 1 and the second positioning frame 2 up and down through a third connecting rod 8;

[0047] Both ends of the third connecting rod 8 are detachably fixed to the first positioning frame 1 and the second positioning frame 2 respectively, and the middle part of the third connecting rod 8 is rotatably connected to the third positioning frame 9 in a horizontal direction perpendicular to the axis of the third positioning frame 9.

[0048] In a specific embodiment of the present application, the third positioning frame 9 has the same structure as the first positioning frame 1 and the second positioning frame 2, and will not be elaborated here. The longitudinal reinforcing rod 4 of the third positioning frame 9 is connected to the intersection of the first connecting rod 6 and the second connecting rod 7, thereby realizing the axial rotation setting of the third positioning frame 9. Both ends of the third connecting rod 8 are respectively abutted against the first positioning frame 1 and the second positioning frame 2, and the middle part of the third connecting rod 8 is rotatably connected to the third positioning frame 9 (with the horizontal direction perpendicular to the axis of the third positioning frame 9 as the rotation axis). During use, by rotating the third connecting rod 8 to the vertical state and abutting against the first positioning frame 1 and the second positioning frame 2 up and down, the third positioning frame 9 is kept in a horizontal state to cooperate with the first positioning frame 1 and the second positioning frame 2 for steel bar positioning.

[0049] To improve the stability of the positioning work of the third positioning frame 9, a plurality of third connecting rods 8 are arranged at intervals along the circumferential direction of the third positioning frame 9.

[0050] To save costs while improving the stability of the positioning work of the third positioning frame 9, a third connecting rod 8 is respectively arranged in the middle of both sides of the third positioning frame 9.

[0051] A plurality of guy wire hanging buckles 12 are arranged at intervals in the circumferential direction of the first positioning frame 1.

[0052] In a specific embodiment of the present application, four guy wire hanging buckles 12 are arranged at intervals in the circumferential direction of the first positioning frame 1, and the four guy wire hanging buckles 12 are respectively near the four corners of the rectangular frame 10. Before the formwork is installed, in case of bad weather, the guy wires are tied to the four guy wire hanging buckles 12 to prevent the pier embedded steel bars and the positioning device from tipping over.

[0053] In other embodiments of the present application, steel bar positioning points are arranged at intervals around the first positioning frame 1 and the second positioning frame 2 according to the design drawing spacing. During the construction process, the steel bars can be quickly tied according to the set positions of the positioning points, which is convenient for construction.

For those skilled in the art, the present application can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
