Description

Technical Field

[0001] This utility model relates to the field of tower structures, and in particular to a reinforcement structure for a polyurethane composite material tower. Background Technology

[0002] Polyurethane composite towers are modern towers manufactured using polyurethane fiber-reinforced composite materials, and are widely used in communications, power, and other fields. In conventional tower construction and installation, the bottom of the tower is typically inserted into a foundation pit, which is then filled with concrete. However, concrete is not conducive to cushioning the impact forces on polyurethane composite towers, making them susceptible to damage from external impacts. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a reinforcement structure for polyurethane composite material towers, which facilitates reinforcement between the tower base and the foundation, and makes the tower less susceptible to damage.

[0004] The technical solution of this utility model is as follows:

[0005] A reinforcement structure for a polyurethane composite tower is provided at the bottom end of the tower, including an upper connecting section and a lower connecting section. The bottom end of the tower is provided with an installation section, the bottom of which has a groove for insertion into the upper connecting section. The bottom of the upper connecting section is provided with an upper flange, and the bottom end of the tower abuts against the top surface of the upper flange. The top of the lower connecting section is provided with a lower flange, and anchor bolts for connecting the concrete layer pass through the upper flange and the lower flange.

[0006] In a further technical solution, the thickness and outer diameter of the installation section are both greater than those of the tower.

[0007] In a further technical solution, the outer wall of the installation section and the outer wall of the tower have an arc-shaped transition.

[0008] In a further technical solution, fastening bolts are provided between the mounting section and the upper connecting section.

[0009] In a further technical solution, the lower connecting section is provided with an embedded layer extending to the inside of the tower.

[0010] In a further technical solution, the inner layer is a steel frame, with its top extending into the tower and fitting against the inner wall of the tower.

[0011] In a further technical solution, the inner layer is cast concrete.

[0012] The beneficial effects of this utility model are:

[0013] 1. The embedded upper connecting section reinforces the bottom of the tower, and the lower connecting section is connected to the upper connecting section through a flange and is buried in the foundation pit instead of the bottom of the tower. It is stable under the action of anchor bolts and has a stronger impact resistance.

[0014] 2. Using fastening bolts can further strengthen the connection between the upper connecting section and the tower;

[0015] 3. The inner layer supports the inner side of the bottom end of the tower and the inner side of the lower connecting section, and the bottom end of the tower is reinforced both inside and out, making it less prone to deformation and damage. Attached Figure Description

[0020] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0021] Example 1:

[0022] like Figure 1 As shown, a reinforcement structure for a polyurethane composite tower is provided at the bottom end of the polyurethane composite tower 10, including an upper connecting section 20 and a lower connecting section 30, both of which are hollow columns; an installation section 11 is provided at the bottom end of the tower 10, the thickness and outer diameter of the installation section 11 are both greater than the bottom end of the tower 10, and the outer wall of the installation section 11 has an arc transition with the outer wall of the tower 10 to avoid stress concentration, and can be connected to the upper connecting section 20 while ensuring the strength of the installation section 11;

[0023] The bottom of the installation section 11 is provided with a groove for insertion into the upper connecting section 20. The bottom of the upper connecting section 20 is provided with an upper flange 21. The bottom end of the tower 10 abuts against the top surface of the upper flange 21. The top of the lower connecting section 30 is provided with a lower flange 31. Anchor bolts 40 for connecting the concrete layer 50 are inserted between the upper flange 21 and the lower flange 31. The top of the anchor bolts 40 is connected by nuts 41. The bottom of the nuts 41 is located on the top of the upper flange 21 and can be welded to the upper flange 21 for fixation.

[0024] The lower connecting section 30 has an embedded layer extending to the inner side of the tower 10; the embedded layer can be a steel frame, which may include a top support ring 61, a bottom support ring 62 and supporting steel bars 63, wherein the bottom support ring 62 is located at the bottom of the inner side of the lower connecting section 30, and the supporting steel bars 63 are arranged in a ring array vertically between the top support ring 61 and the bottom support ring 62, and the top support ring 61 can fit against the inner wall of the tower 10 for strong support.

[0025] The working principle of the above technical solution is as follows:

[0026] When installing tower 10, the bottom end of tower 10 is first reinforced by the embedded upper connecting section 20. The lower connecting section 30 is connected to the upper connecting section 20 through a flange and buried in the foundation pit to replace the bottom end of tower 10. It is set on the concrete cushion layer and concrete is poured. It is stable under the action of anchor bolts 40 and has a stronger impact resistance.

[0027] Example 2:

[0028] like Figure 2 As shown, the difference from Embodiment 1 is that the inner layer is a concrete structure 70 cast inside the lower connecting section 30.

[0029] In another embodiment, such as Figure 1-2 As shown, fastening bolts 80 are inserted between the installation section 11 and the upper connecting section 20, and the fastening bolts 80 are evenly distributed circumferentially.

[0030] Using fastening bolts 80 can further strengthen the connection between the upper connecting section 20 and the tower 10.

[0031] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
