Description

Technical Field

[0001] The utility model relates to the technical field of pipe tower fixing, in particular to a tower foot reinforcement device suitable for three-tube towers and four-tube towers. Background Art

[0002] Three-tube and four-tube towers are important transmission towers in power transmission projects and are widely used in the field of signal communication. To ensure the normal operation of power transmission, the transmission towers should be stably fixed to the ground and have certain wind resistance and ice resistance requirements. However, during long-term outdoor use, they are easily corroded by the natural environment and weathering. In addition, the increase in load on the tower will cause the anchor bolts to have insufficient bearing capacity, which may cause the tower to collapse and directly affect the stability of the tower.

[0003] In the prior art, the Chinese utility model with publication number: CN213204240U discloses a tower foot reinforcement device suitable for three-tube towers and four-tube towers. It includes original anchor bolts, new anchor bolts and gaskets. The new anchor bolt holes Ⅰ are evenly distributed along the outer side of the original anchor bolts. The new anchor bolts are inserted into the new anchor bolt holes Ⅰ. The new anchor bolts are one nut width away from the edge of the bottom flange. The gaskets are sleeved on the upper ends of the original anchor bolts and the new anchor bolts. The original anchor bolts are fixed with the original nuts. The new anchor bolts are fixed with the new nuts Ⅰ and Ⅱ. The tops of the original nuts and the tops of the new nuts Ⅰ are flush with each other. Compared with the traditional new foundation, taking the new 45-meter four-tube tower raft foundation as an example, the cost is reduced by about 97%, which greatly saves investment costs. The safety hazards are small. The reinforcement and transformation are carried out while maintaining the existing bearing capacity, which will not weaken the existing bearing capacity and does not require the addition of temporary supports. It saves time and space, reduces safety risks, and ensures the stability of the reinforcement.

[0004] Although the above technical solution adds new anchor bolts inserted into the foundation to increase the load-bearing capacity, the effect of the pipe tower in supporting and resisting the three-tube tower or the four-tube tower through the anchor bolts alone is limited. Under the action of strong wind, the three-tube tower and the four-tube tower will shake, thereby affecting the connection stability between the anchor bolts and the foundation, causing the connection between the tower foot and the foundation to break. Therefore, we need to propose a tower foot reinforcement device suitable for three-tube towers and four-tube towers. Utility Model Content

[0005] The purpose of the utility model is to provide a tower foot reinforcement device suitable for three-tube towers and four-tube towers, to increase the docking structure of the three-tube towers and four-tube towers installed on the foundation, so that the tower foot and the docking mechanism on the foundation can be stably docked. Compared with the single anchor bolt connection, the stability of the tower foot installed on the foundation is increased, the connection contact surface is increased, and the stability of the installation of the three-tube tower and the four-tube tower is improved, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present utility model provides the following technical solution: A tower foot reinforcement device applicable to three-tube towers and four-tube towers, including a concrete foundation and a tower foot tube.

One group of inner stirrups is arranged between multiple groups of right-angle long ribs and multiple groups of connecting ribs, and the other group of inner stirrups is welded at the corner ends of multiple groups of right-angle long ribs.

[0009] Preferably, an outer stirrup is sleeved outside multiple groups of right-angle long ribs. The distance between the outer stirrup and the two groups of inner stirrups is the same, and the diameter of the outer stirrup is larger than the diameters of the two groups of inner stirrups.

[0010] Preferably, a buffer pad is arranged between the positioning flange and the tower foot flange. The buffer pad is provided with round holes for multiple groups of positioning blocks and multiple groups of inner bolts to pass through.

[0023] Please refer to Figures 1-5, the present utility model provides a technical solution: a tower foot reinforcement device applicable to three-tube towers and four-tube towers, including a concrete foundation 1 and a tower foot 2. A docking structure 8 is poured in the concrete foundation 1. The lower end of the tower foot 2 is fixedly connected with a tower foot flange 4. Multiple groups of second jacks 10 are opened on the tower foot flange 4, and multiple groups of positioning blocks 11 are fixedly connected to the lower surface of the tower foot flange 4;

[0024] The docking structure 8 includes a counterpoint flange 81. The upper surface of the counterpoint flange 81 is provided with first jacks 87 for multiple groups of positioning blocks 11 to be inserted. Multiple groups of inner bolts 86 passing through the second jacks 10 are fixedly connected to the upper surface of the counterpoint flange 81. Multiple groups of right-angle long bars 82 and multiple groups of connecting bars 83 are welded to the lower surface of the counterpoint flange 81. The lower ends of the multiple groups of connecting bars 83 are respectively welded to the outer walls of the multiple groups of right-angle long bars 82.

[0025] Two groups of inner stirrups 84 are welded between the multiple groups of right-angle long bars 82. One group of inner stirrups 84 is arranged between the multiple groups of right-angle long bars 82 and the multiple groups of connecting bars 83, and the other group of inner stirrups 84 is welded at the corner ends of the multiple groups of right-angle long bars 82. The multiple groups of right-angle long bars 82 are supported by the inner stirrups 84 to keep the multiple groups of right-angle long bars 82 vertical, and under the action of the multiple groups of connecting bars 83, the adjacent right-angle long bars 82 are arranged at equal intervals to ensure uniform load-bearing capacity.

[0026] An outer stirrup 85 is sleeved outside the multiple groups of right-angle long bars 82. The distance between the outer stirrup 85 and the two groups of inner stirrups 84 is the same, and the diameter of the outer stirrup 85 is larger than the diameter of the two groups of inner stirrups 84. The right-angle long bars 82 are further limited by the outer stirrup 85 to improve the support strength of the steel reinforcement cage formed by the right-angle long bars 82, connecting bars 83, inner stirrups 84, and outer stirrups 85, thereby improving the support effect on the pipe tower. Both the inner stirrup 84 and the outer stirrup 85 are round steel bars, and the right-angle long bar 82 is a ribbed steel bar.

[0027] A buffer pad 7 is arranged between the counterpoint flange 81 and the tower foot flange 4. The buffer pad 7 is provided with round holes for multiple groups of positioning blocks 11 and multiple groups of inner bolts 86 to pass through. The buffer pad 7 can buffer when supporting the pipe tower and reduce the influence of wind force.

[0028] A reinforcing gasket 6 penetrates through the upper end of the inner bolt 86. Two groups of first locking nuts 12 are threadedly connected to the upper end of the inner bolt 86. Multiple groups of reinforcing plates 3 are welded to the upper surface of the tower foot flange 4. The multiple groups of reinforcing plates 3 and the multiple groups of reinforcing gaskets 6 are alternately arranged.
