Description

Technical Field

[0001] This utility model relates to the field of communication towers, and in particular to a plug-in polyurethane composite material pole tower. Background Technology

[0002] The plug-in tower structure mainly involves inserting the lower end of the upper tower section directly into the upper end of the lower tower section. The load is transferred through tight fit and auxiliary fixing. The conventional plug-in structure is relatively simple and can achieve mechanized and rapid construction, significantly shortening the construction period. However, in areas with strong winds, the connection of the conventional plug-in tower may loosen or deform after long-term use, resulting in higher maintenance costs. Utility Model Content

[0003] To address the aforementioned issues, this utility model provides a plug-in polyurethane composite material tower, suitable for plug-in installation of towers in areas with high wind speeds, resulting in a more stable connection and easier maintenance.

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

[0005] A plug-in polyurethane composite material tower includes several polyurethane composite material tower segments that are plugged in sequentially from top to bottom. Each tower segment has an inner lining segment at the top and an outer lining segment at the bottom. The bottom of the inner lining segment has a first flange, and the bottom of the outer lining segment has a second flange. Between two adjacent tower segments, the outer lining segment of the higher tower segment is fitted onto the outside of the inner lining segment of the lower tower segment, and the first flange and the second flange are fitted together and bolted together.

[0006] In a further technical solution, a first reinforcing rib is provided on the outer wall of the tower section on the bottom side of the first flange.

[0007] In a further technical solution, the top side of the first flange is provided with a positioning protrusion, and the second flange is provided with a positioning groove that matches the positioning protrusion.

[0008] In a further technical solution, a number of reinforcing screws are inserted between the outer sleeve section and the inner lining section.

[0009] In a further technical solution, an inner support ring is provided on the top inner side of the outer sleeve section, and the bottom of the inner support ring abuts against the top of the inner lining section.

[0010] In a further technical solution, the inner wall of the tower section at the top of the inner support ring is provided with a second reinforcing rib.

[0011] The beneficial effects of this utility model are:

[0012] 1. The tower section is connected to the inner lining section through the outer sleeve section. At the same time, the first flange and the second flange of the two can fit together and abut against each other. The first flange and the second flange of this setting provide support while being bolted together, making the connection more stable. It is suitable for areas with strong winds, is not easy to loosen or deform, and helps to reduce the maintenance cost of the plug-in structure.

[0013] 2. The structure of the protrusion and positioning groove allows for quick alignment of the first and second flanges, facilitating installation;

[0014] 3. The reinforcing screws can reinforce the connection between the inserted outer and inner lining sections, and generate sufficient friction on the short contact surfaces of the outer and inner lining sections to resist shear forces. This, combined with the support of the inner support ring, can further improve the structural stability. Attached Figure Description

[0019] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0020] Example:

[0021] like Figures 1-2As shown, a plug-in polyurethane composite tower includes several polyurethane composite tower segments plugged in sequentially from top to bottom. Except for the topmost tower segment, the top of the remaining tower segments is provided with an inner lining segment 20, and except for the bottommost tower segment, the bottom of the remaining tower segments is provided with an outer sleeve segment 10. The bottom of the inner lining segment 20 is provided with a first flange 21, and the bottom of the outer sleeve segment 10 is provided with a second flange 11. Between two adjacent tower segments, the outer sleeve segment 10 of the higher tower segment is fitted onto the outside of the inner lining segment 20 of the lower tower segment, and the first flange 21 and the second flange 11 are connected... The flanges 11 are fitted together. The first flange 21 has multiple first connecting holes 22 arranged in a ring array. The second flange 11 has second connecting holes arranged in a ring array corresponding to the first connecting holes 22. Bolts are inserted through the first connecting holes 22 and the second connecting holes to connect the first flange 21 and the second flange 11. The bolts connecting the first flange 21 and the second flange 11 can be hot-dip galvanized bolts. The outer wall of the tower section on the bottom side of the first flange 21 can be provided with a first reinforcing rib 24 to improve the structural strength of the first flange 21 and make it less prone to deformation.

[0022] The working principle of the above technical solution is as follows:

[0023] The tower section is connected to the inner lining section 20 through the outer sleeve section 10. At the same time, the first flange 21 and the second flange 11 of the two can fit together and abut against each other. The first flange 21 and the second flange 11 of this configuration provide support while being bolted together, making the connection more stable. This is suitable for areas with strong winds, as it is not easy to loosen or deform, and it helps to reduce the maintenance cost of the plug-in structure.

[0024] In another embodiment, such as Figure 1-2 As shown, the first flange 21 is provided with a positioning protrusion 23 on its top side, and the second flange 11 is provided with a positioning groove matching the positioning protrusion 23. The positioning protrusion 23 may include multiple protrusions, which are arranged in a ring array between adjacent first connecting holes 22. Several reinforcing screws 30 are vertically inserted between the outer sleeve section 10 and the inner lining section 20. The reinforcing screws 30 may be arranged in a ring array and arranged in two rows along the vertical direction.

[0025] The structure of the protrusion and positioning groove allows the first flange 21 and the second flange 11 to be quickly aligned, facilitating installation. The reinforcing screw 30 can reinforce the connection between the inserted outer sleeve section 10 and the inner liner section 20, and generate sufficient friction on the contact surfaces of the outer sleeve section 10 and the inner liner section 20 to resist shear force. The reinforcing screw 30, in conjunction with the connection of the first flange 21 and the second flange 11, prevents the outer sleeve section 10 and the inner liner section 20 from twisting relative to each other.

[0026] In another embodiment, such as Figure 1 As shown, the inner top of the outer sleeve section 10 is provided with an inner support ring 12, and the bottom of the inner support ring 12 abuts against the top of the inner lining section 20; the inner wall of the tower section at the top of the inner support ring 12 is provided with a second reinforcing rib 13.

[0027] In this embodiment, the tower rod made of polyurethane composite material can be installed by setting a metal inner liner tube to install the first flange 21, the second flange 11 and the inner support ring 12. This installation structure can be achieved by existing technology.

[0028] The support ring can provide further support and further improve the structural stability. The second reinforcing rib 13 improves the structural strength of the inner support ring 12 and makes it less prone to deformation.

[0029] 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.
