[0044] Embodiment 2

[0045] Referring to Figures 6-10 As shown, the spiral bar fixing device for the steel cage provided in the present application includes at least two hoop members 10 and a fixing component 20 provided on each hoop member 10.

[0046] The hoop member 10 is made of a hard material. For example, it is made of steel bars at the construction site, which can not only improve its structural strength but also save material costs. At least two hoop members 10 are configured to enclose the periphery of the steel cage 100. Specifically, as Figure 1 shown, the cross-sectional shape of the steel cage 100 is circular or approximately circular, and the shape of the inner circle enclosed by each hoop member 10 is the same as the cross-sectional shape of the steel cage 100.

[0047] Before the spiral bar is wound on the steel cage 100, stirrups 102 are welded at preset intervals (1 m - 2 m) along the length direction of the steel cage 100. The stirrups 102 support each main bar 101 of the steel cage 100, so that each main bar 101 is connected as a whole to form the steel cage 100.

[0048] As Figures 6-10 shown, the fixing component 20 is configured to fixedly connect the main bar 101 of the steel cage 100 to fix the main bar 101 of the steel cage 100. Furthermore, the steel cage 100 is positioned by the present spiral bar fixing device, the bonding strength of each main bar 101 of the steel cage 100 is improved, and jamming during the spiral bar winding process is prevented, so as to further improve the quality and efficiency of spiral bar winding.

[0049] In practical applications, the steel cage 100 can be fixed by at least two hoop members 10. During the spiral bar winding process, the steel cage 100 is placed on two rollers 200 of the spiral bar winding machine. After winding a section of spiral bar 103, the previous fixing device is removed and the next fixing device is installed. Compared with the welding fixing method in the related art, the assembly efficiency can be improved, the winding efficiency can be further improved, and the labor cost of removing or welding the reinforcement bars can be reduced.

There are two screw holes 251 on the fixing piece 25. The fixing piece 25 is a convex block structure on the hoop piece 10 and is an integral structure with the fixing piece 10. The U-shaped screw rod 24 passes through the two screw holes 251, and the main reinforcement 101 of the steel reinforcement cage 100 is located between the two screw rods of the U-shaped screw rod 24. The fixing piece 25 is fixed to the U-shaped screw rod 24 to fix the main reinforcement 101 of the steel reinforcement cage 100.

[0052] In this embodiment, two screw holes 251 are provided on the fixing piece 25. The two screw rods of the U-shaped screw rod 24 are inserted into the two screw holes 251 of the fixing piece 25, and two locking nuts 26 are respectively screwed onto the two screw rods of the U-shaped screw rod 24, so as to fix the main reinforcement 101 of the steel reinforcement cage 100.

[0053] In some embodiments, the position of the main reinforcement 101 of the steel reinforcement cage 100 is deviated. In this regard, the screw hole 251 is set as an oval hole, so that the position of the U-shaped screw rod 24 can be adjusted to adapt to the position of the main reinforcement 101.

[0054] In this application, among at least two hoop pieces 10, the shapes of the hoop pieces 10 are the same or different. In this embodiment, the shapes of the hoop pieces 10 are the same, and two hoop pieces 10 are provided, and each hoop piece 10 is semi-circular.

[0055] In this embodiment, at least three fixing components 20 are provided on the hoop piece 10. In other words, at least three hoop pieces 10 can fix at least three main reinforcements 101 of the steel reinforcement cage 100 to improve the connection strength of the main reinforcements 101 in the steel reinforcement cage 100.

[0056] In summary, the spiral reinforcement fixing device for hanging the steel reinforcement cage provided by this application fixes the main reinforcement of the steel reinforcement cage on each hoop piece through the fixing component, and each hoop piece is surrounded and fixed on the periphery of the steel reinforcement cage. Compared with the welding fixing method in the related technology, the assembly efficiency can be improved, the winding efficiency can be further improved, and the labor cost of removing or welding the measure steel bars can be reduced. After the winding is completed, this positioning device can be removed for secondary recycling, reducing the construction cost of the product and improving the production efficiency.
