Description

Technical Field

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

[0002] The plug-in structure of composite material towers mainly achieves the connection between tower segments through tapered sleeves, specialized anti-torsion design, and optimized contact interfaces. This design aims to ensure structural stability, reliable force transmission, and ease of installation. Common anti-torsion designs involve inserting bolts or fixing pins between tower segments, which is usually installed after plugging, making it more cumbersome and prone to stress concentration. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a plug-in structure for composite material tower bodies, which is simple and convenient to install and less prone to stress concentration.

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

[0005] A composite material tower body insertion structure is provided between composite material conical tower segments that are inserted end to end. It includes a first slot and a first insert block adapted to it. The first slot is evenly distributed on the top outer wall of the tower segment, and the first insert block is evenly distributed on the bottom inner wall of the tower segment. When two adjacent tower segments are inserted, the first insert block of the higher tower segment is inserted into the first slot of the lower tower segment.

[0006] In a further technical solution, the top of the first insert block is provided with a first support ring that connects to the inner wall of the tower section.

[0007] In a further technical solution, a second slot and a matching second plug are also included. The second slot is circumferentially and evenly opened on the inner wall of the bottom end of the tower segment, and the second plug is circumferentially and evenly arranged on the outer wall of the top of the tower segment. When two adjacent tower segments are inserted, the second slot of the higher tower segment is inserted into the second plug of the lower tower segment.

[0008] In a further technical solution, the bottom of the second insert block is provided with a second support ring that connects to the outer wall of the tower section.

[0009] In a further technical solution, the top opposite side walls of the first slot are inclined in a direction away from each other to form a funnel opening; the bottom opposite side walls of the second slot are inclined in a direction away from each other to form a funnel opening.

[0010] In a further technical solution, the bottom of the second support ring is provided with reinforcing ribs.

[0011] In a further technical solution, marking elements are provided on the bottom of the tower segment and the outer wall of the tower segment at the bottom of the second support ring, respectively, for quickly identifying the alignment position when the two tower segments are inserted.

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

[0013] 1. An insertion structure is set at the position of the tower segment insertion. With the inner and outer walls of the tower segments fitting together, the insertion structure can prevent the tower segments from twisting to each other. This structure can achieve complete installation after the tower segment insertion is completed, reducing the operation after insertion. The installation is simple and does not require additional installation of bolts or fixing pins, which are structures that are prone to stress concentration. In addition, the insertion block can also serve as a reinforcing structure to enhance the strength and reliability of the insertion point.

[0014] 2. The flared opening of the slot and the markings facilitate alignment during insertion, enabling quick installation and reducing construction time. Attached Figure Description

[0021] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0022] Example:

[0023] like Figures 1-4As shown, a composite material tower body insertion structure is provided between composite material conical tower segments 1 that are inserted end to end. It includes a first slot 2, a first insert 3, a second slot 4, and a second insert 5, wherein the first slot 2 and the first insert 3 are adapted to each other, and the second slot 4 and the second insert 5 are adapted to each other. The first slot 2 is evenly distributed around the top outer wall of the tower segment 1, and the first insert 3 is evenly distributed around the bottom inner wall of the tower segment 1. The second slot 4 is evenly distributed around the bottom inner wall of the tower segment 1, and the second insert 5 is evenly distributed around the top outer wall of the tower segment 1. When two adjacent tower segments 1 are inserted, the first insert 3 of the higher tower segment 1 is inserted into the first slot 2 of the lower tower segment 1, and the second slot 4 of the higher tower segment 1 is inserted into the second insert 5 of the lower tower segment 1. The positions of the first insert 3 and the second insert 5 depend on the actual insertion depth between the tower segments 1.

[0024] The working principle of the above technical solution is as follows:

[0025] The insertion of the first slot 2 and the first insert 3, and the insertion of the second slot 4 and the second insert 5, reinforce each other and prevent the tower segments 1 from twisting against each other while ensuring the inner and outer walls of the tower segments 1 are in close contact. After the tower segments 1 are inserted, the high-performance epoxy resin or polyurethane structural adhesive applied to the inserted tower segments 1 can achieve complete installation, reducing the number of operations after insertion. The installation is simple and does not require additional installation of bolts or fixing pins, which are prone to stress concentration. In addition, the inserts can also serve as a reinforcing structure to enhance the strength and reliability of the insertion joint.

[0026] In another embodiment, such as Figure 3-4 As shown, the top of the first insert 3 is provided with a first support ring 6 that connects to the inner wall of the tower section 1. When the first support ring 6 is inserted, its bottom surface abuts against the top surface of the tower section 1. The bottom of the second insert 5 is provided with a second support ring 7 that connects to the outer wall of the tower section 1. When the second support ring 7 is inserted, its top surface abuts against the bottom surface of the tower section 1. A reinforcing rib 8 can be arranged around the bottom of the second support ring 7.

[0027] The first support ring 6 and the second support ring 7 provide further support to the top and bottom of the tower section 1, respectively, enhancing the reliability of the structure; the reinforcing rib 8 strengthens the structural stability of the second support ring 7, making the second support ring 7 less susceptible to compression deformation.

[0028] In another embodiment, such as Figure 2 As shown, the top opposite side walls of the first slot 2 are inclined in a direction away from each other to form a flared opening. Similarly, the bottom opposite side walls of the second slot 4 can be inclined in a direction away from each other to form a flared opening. In addition, the bottom of the tower segment 1 and the outer wall of the tower segment 1 at the bottom of the second support ring 7 are respectively provided with identification pieces of arbitrary structure to quickly identify the alignment position when the two tower segments 1 are inserted.

[0029] The placement of the first slot 2 and the second slot 4 facilitates the entry of the first insert 3 and the second insert 5, respectively. With the alignment of the markings, quick insertion and installation can be achieved, reducing construction time.

[0030] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but 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 several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
