Technical Field

[0001] The utility model belongs to the technical field of construction, and in particular relates to a fixing tool for a tower reinforcement cage. Background Art

[0002] Towers, as the foundation of a building, play a crucial supporting role. They are typically cylindrical or semi-cylindrical in shape, supporting, for example, a crucial component of a wind turbine generator system. Towers often incorporate a steel cage structure to increase structural strength and deformation resistance, thereby improving stability. The tower cage is typically constructed on a steel cage formwork. After the cage is tied, it is hoisted onto the mold using a crane for assembly.

[0003] To facilitate smooth mold assembly and installation of the tower's reinforcement cage, it is typically designed as two semicircular structures, which are then hoisted onto the mold using a crane and assembled. However, simply joining the two semicircular structures together presents significant construction difficulties and is prone to misalignment during installation, increasing the construction time and compromising quality.

[0035] In one embodiment, please refer to Figures 1 to 9The present application provides a fixing tool 100 for a tower steel cage, comprising: a support base 10, located between two semicircular steel cages 200, and provided with a through-hole 13 on the support base 10; an adjusting shaft 20, passed through the through-hole 13, and both ends of the adjusting shaft 20 extend into the semicircular steel cages 200 on both sides, and both ends of the adjusting shaft 20 are provided with external threads 21; two fixing components 30, each fixing component 30 includes an adjusting nut 31 and an abutment component 32, each abutment component 32 is located in the semicircular steel cage 200 corresponding to each other and is sleeved on the adjusting shaft 20, the adjusting nut 31 is screwed to one end of the adjusting shaft 20 and is located on the side of the abutment component 32 facing away from the support base 10, the adjusting nut 31 is used to drive the abutment component 32 to abut against the support frame 210 in the semicircular steel cage 200, wherein each semicircular steel cage 200 includes a plurality of support frames 210 and a semicircular steel ring 220 sleeved on the outer circumference of the support frame 210.

[0036] The above-mentioned tower steel cage fixing fixture 100 can be used to align two semicircular steel cages 200 on both sides of the support base 10 during the construction of the sleeve steel cage; then the two fixing components 30 are respectively extended into the corresponding semicircular steel cages 200; since the fixing components 30 include an adjusting nut 31 and abutting components 32, the adjusting nut 31 is rotated to drive the abutting components 32 to move on the adjusting shaft 20, so that the abutting components 32 abut on the support frame 210 of the semicircular steel cage 200. In this way, by tightening the adjusting nuts 31 on both sides and applying force, it is ensured that the semicircular steel cages 200 on both sides quickly abut on both sides of the support base 10. At the same time, with the help of the abutment of the support base 10, instead of the traditional direct docking of the two semicircular steel cages 200, the initial positioning of each semicircular steel cage 200 during installation can be achieved, avoiding the easy occurrence of alignment deviation, which not only facilitates construction and shortens the construction period, but also improves construction quality.

[0037] It should be noted that to facilitate mold assembly, the tower reinforcement cage is constructed by joining two semicircular reinforcement cages 200 together during construction. The semicircular reinforcement cage 200 comprises a plurality of support frames 210 and semicircular reinforcement rings 220 surrounding the outer circumference of the support frames 210. The semicircular reinforcement rings 220 are spaced apart along the height of the support frames 210. The semicircular reinforcement rings 220 and the support frames 210 can be secured by welding or wire tying.

[0038] It should also be explained that in Figure 2 Only one fixing tool 100 is shown in the figure. In actual operation, a fixing tool 100 can be set at both ends of the semicircular steel cage 200.

[0039] For further information, please refer to Figure 4The abutting component 32 includes a mounting plate 321 and two abutting blocks 322. The mounting plate 321 is slidably mounted on the adjustment shaft 20. The two abutting blocks 322 are respectively connected to both sides of the mounting plate 321 and abut against the support frame 210. The adjusting nut 31 is used to drive the mounting plate 321 to move on the adjustment shaft 20. It can be seen that the abutting component 32 is designed as a mounting plate 321 and two abutting blocks 322, so that the adjusting nut 31 drives the mounting plate 321 to move, thereby driving the abutting blocks 322 to stably abut against the support frame 210, ensuring that the adjustment of the fixing assembly 30 is more convenient; at the same time, the abutting blocks 322 are provided on both sides of the mounting plate 321 to facilitate force balance and improve the stability of the tower steel cage structure.

[0040] It should be noted that the connection between the two abutting blocks 322 and the mounting plate 321 can be direct or indirect, for example, the abutting blocks 322 are fixed to one side of the mounting plate 321 through other structures.

[0041] For further information, please refer to Figure 5 and Figure 6 The abutting component 32 further includes two fixing ribs 324, which are respectively fixed to the upper and lower ends of the mounting plate 321, and each abutting block 322 is fixed between the two fixing ribs 324. It can be seen that the two fixing ribs 324 make the abutting block 322 more stably fixed on the mounting plate 321.

[0042] Among them, the connection between the fixing rib 324 and the mounting plate 321 can be but not limited to welding, bolt connection, riveting, clamping, etc.; similarly, the connection method between the fixing rib 324 and the abutment block 322 can also be but not limited to welding, bolt connection, riveting, clamping, etc.

[0043] In one embodiment, please refer to Figure 6 Each abutment block 322 has a groove 323 on its side facing away from the adjustment nut 31. The groove 323 is used to engage with the vertical ribs in the support frame 210. As can be seen, each abutment block 322 has a groove 323 on one side. By engaging with the vertical ribs of the support frame 210 through the groove 323, the abutment block 322 is tightly connected to the support frame 210, further improving the stability of the fixation.

[0044] It should be noted that the shape of the groove 323 can be designed to be consistent with the shape of the vertical reinforcement, so that the groove 323 is more stably stuck on the vertical reinforcement. At the same time, the groove wall of the groove 323 can also be provided with anti-slip grooves to increase the bonding force between the groove 323 and the vertical reinforcement. The vertical reinforcement refers to the steel bars placed vertically in the support frame 210. In the support frame 210, there are multiple vertical reinforcements. For example, in a square support frame 210, there are generally four vertical reinforcements, and the four vertical reinforcements can be wrapped together by the steel bars.

[0045] In one embodiment, please refer to Figure 9 The support base 10 includes two support plates 11 and a connecting block 12. The two support plates 11 are arranged side by side and spaced apart. The through holes 13 pass through the two support plates 11. The connecting block 12 is connected between the two support plates 11. It can be seen that the support base 10 with a stable structure is formed.

[0046] The connection between the two support plates 11 of the connection block 12 may be, but is not limited to, welding, clamping, bolt connection, etc.

[0047] In one embodiment, please refer to Figure 8 The support base 10 is also provided with an adjustment channel 14. There are multiple perforations 13, and all the perforations 13 are spaced apart along the height direction of the support base 10. The adjustment channel 14 is located on one side of each perforation 13 and extends along the height direction of the support base 10. Each perforation 13 is connected to the adjustment channel 14. It can be seen that the perforations 13 are provided in multiple numbers, and the adjustment channel 14 is provided on one side of the perforations 13, so that each perforation 13 is connected to the adjustment channel 14. In this way, the adjustment shaft 20 can be moved from one of the perforations 13 to the adjustment channel 14, and then moved in the adjustment channel 14 along the height direction of the support base 10, so that the adjustment shaft 20 reaches the required height and then moves to the corresponding perforation 13, thereby achieving effective adjustment of the position of the adjustment shaft 20, so that the fixing fixture 100 can meet the needs of fixing different sizes and different positions, thereby improving the scope of application of the fixing fixture 100.

[0048] In one embodiment, please refer to Figure 7 The adjusting shaft 20 is provided with a first limiting plate 22 and a second limiting plate 23 spaced apart along its axial direction. The first limiting plate 22 and the second limiting plate 23 are respectively located on either side of the support base 10, and the first limiting plate 22 and the second limiting plate 23 are respectively used to limit the position of the support base 10. In this way, the adjusting shaft 20 is prevented from being pulled out of the through hole 13 during the construction process.

[0049] For further information, please refer to Figure 7 , also includes an elastic member 25, and a fixed plate 24 is provided on the adjusting shaft 20. The first limiting plate 22 and the fixed plate 24 are fixed on the adjusting shaft 20 at intervals. The second limiting plate 23 is located between the first limiting plate 22 and the fixed plate 24, and is slidably sleeved on the adjusting shaft 20. The second limiting plate 23 is connected to the fixed plate 24 through the elastic member 25.

[0050] As can be seen, the second limit plate 23 is elastically extendable on the adjustment shaft 20. This design allows the second limit plate 23 to always abut against the support base 10, ensuring a more stable structure for the fixing fixture 100. Furthermore, the elastic design of the second limit plate 23 facilitates fine-tuning of the adjustment shaft 20 in the axial direction, allowing the adjustment shaft 20 to be adjusted accordingly based on the structural design of the semi-circular reinforcement cage 200 on one side. This not only facilitates construction but also allows the semi-circular reinforcement cage 200 to be better fixed together, forming a structurally stable tower reinforcement cage.

[0051] The elastic member 25 may be, but is not limited to, a spring, an elastic rubber sleeve, etc.

[0052] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
