Description

Technical Field

[0001] This invention relates to the field of building structure technology, and in particular to a single-tube tower reinforcement device. Background Technology

[0002] With the promotion of tower co-construction and sharing, the antenna load on existing monotube communication towers is increasing. The displacement at the top and the strength of the tower body of many existing monotube towers cannot meet the requirements of current specifications after the addition of antennas, necessitating a simple and effective reinforcement method to meet relevant construction needs. Simultaneously, due to the complex and variable surrounding environment of monotube towers, a reinforcement method with a small footprint and significant reinforcement effect is needed to improve the overall rigidity and strength of monotube towers.

[0003] Traditional reinforcement methods for monotube towers, such as strengthening the tower body by adding steel supports, require a large area, are costly, and involve complex and lengthy construction. While traditional cable-stayed reinforcement of monotube towers requires a large site and reliable surrounding fixed nodes, its reinforcement effect on tower stiffness is insufficient when the cable angle is small. Achieving good reinforcement requires a significant amount of space. For details on traditional guyed reinforcement methods, please refer to [link to relevant documentation]. Figure 3 .

[0004] Therefore, it is necessary to provide a single-tube tower reinforcement device to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a single-tube tower reinforcement device. By arranging hyperbolic paraboloid cables on the single-tube tower body to reinforce the tower, the horizontal component of the cable tension can be increased through the reasonable arrangement of multiple cables and the hyperbolic paraboloid shape of the tower body, thereby improving the horizontal reinforcement effect of the cables. After reinforcement, the load-bearing capacity and stiffness of the single-tube tower body can be significantly improved.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] The purpose of this invention is to provide a single-tube tower reinforcement device for reinforcing the body of a single-tube tower. The single-tube tower reinforcement device includes: a single-tube tower cantilever beam node, a cable, a top fixing node for the cable, and a bottom fixing node for the cable. The cable is arranged in a hyperbolic paraboloid shape around the single-tube tower body. The upper end of the cable is fixed by the top fixing node. The lower end of the cable is fixed by the bottom fixing node. The single-tube tower cantilever beam node is disposed on the single-tube tower body. The middle part of the cable is fixed by the single-tube tower cantilever beam node.

[0008] Furthermore, the cable is a steel cable.

[0009] Furthermore, the single-tube tower cantilever beam node includes 6 to 18 evenly distributed cantilever beams; the cantilever beams are connected to the single-tube tower body through a second clamp.

[0010] Furthermore, the number of cables ranges from 6 to 18, which is the same as the number of cantilever beams.

[0011] Optionally, the top fixing node of the cable includes a node plate with reserved bolt holes; the number of node plates with reserved bolt holes is the same as that of the cantilever beam and they are arranged in parallel in a one-to-one correspondence.

[0012] Furthermore, the upper end of the cable is fixed to the monotube tower body via a cable top fixing node; the cable top fixing node is connected to the monotube tower body via a first clamp.

[0013] Optionally, the bottom fixing node of the cable includes a chemical anchor; the lower end of the cable is fixed to the monotube tower foundation platform by the chemical anchor.

[0014] Optionally, the bottom fixing node of the cable includes a helical pile; the lower end of the cable is fixed to the perimeter of the monotube tower foundation by the helical pile.

[0015] Furthermore, the straight line determined by the cantilever beam node of the single-tube tower and the bottom fixed node of the cable should have an angle of not less than 20° with the center line of the single-tube tower body, in order to increase the horizontal component of the cable tension, thereby increasing the reinforcement effect.

[0016] Furthermore, the single-tube tower is narrower at the top and wider at the bottom.

[0017] Furthermore, the cantilever beam node of the single-tube tower is set at one-quarter to three-quarters of the total height of the single-tube tower.

[0018] Furthermore, the top fixing node of the cable is located above the node of the single-tube tower cantilever beam; the top fixing node of the cable is located 1 to 2 meters above the node of the single-tube tower cantilever beam.

[0019] Preferably, as the number of antennas or other equipment mounted on the monotube tower increases, the wind load on the monotube tower also increases, which can cause the tower top displacement and the tower body strength to exceed the specifications. This can be addressed by arranging hyperbolic paraboloid cables on the monotube tower body for reinforcement. Several cantilever beam nodes are set on the monotube tower body, corresponding to several newly added cable bottom fixing nodes and cable top fixing nodes. Reinforcement is achieved by installing cables between the nodes. The cables form a certain angle with the monotube tower body to increase the horizontal component of the cable tension, thereby improving the reinforcement effect. The cantilever beam nodes and cable top fixing nodes should be connected to the monotube tower body via clamps. Since monotube towers are generally narrower at the top and wider at the bottom, and when wind loads act on the monotube tower, the force on the upper nodes is downward in the vertical direction, thus ensuring the force transmission between the nodes and the tower body. Meanwhile, because the forces on the upper and lower cables can be canceled out in the vertical direction, the cantilever beam is mainly subjected to compressive forces, which allows for a significant reduction in the cross-section of the cantilever beam.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The single-tube tower reinforcement device provided by this invention arranges hyperbolic paraboloid-shaped cables on the tower body for reinforcement. Uniformly distributed cantilever beams are set at a certain height on the tower body as the central fixing points of the cables. The upper cables of the cantilever beams are connected to the tower body via clamp nodes, and the lower cables are fixed to the pile cap of the cast-in-place pile foundation by planting chemical anchors or by using helical piles. Through the reasonable arrangement of multiple cables and the hyperbolic paraboloid shape of the tower body, the horizontal component of the cable tension can be increased, thereby improving the horizontal reinforcement effect of the cables.

[0022] 2. The single-tube tower reinforcement device provided by this invention can significantly improve the load-bearing capacity and rigidity of the single-tube tower body after reinforcement. The reinforcement cost is low, the reinforcement area is small, the reinforcement method is simple, the operation is strong, the overall rigidity reinforcement effect of the single-tube tower is obvious, and the aesthetics are good.

[0023] 3. When the stiffness or strength of a single-tube tower fails to meet relevant national standards due to the addition of antenna loads to the tower body, the single-tube tower body reinforcement device provided by this invention can be used to reinforce the single-tube tower body.

[0024] 4. The single-tube tower reinforcement device provided by this invention can increase lateral stiffness and resist bending; it can be used in the main body of the communication industry. Attached Figure Description

[0032] Example

[0033] This embodiment provides a single-tube tower reinforcement device for reinforcing a single-tube tower body 1 that is narrow at the top and wide at the bottom, with a single-tube tower height of 30m.

[0034] like Figure 1 , 2 As shown, the single-tube tower reinforcement device includes: a single-tube tower cantilever beam node 5, a cable 2, a cable top fixing node 3, and a cable bottom fixing node 4; the cable 2 is arranged in a hyperbolic paraboloid shape around the single-tube tower body 1; the upper end of the cable 2 is fixed by the cable top fixing node 3; the lower end of the cable 2 is fixed by the cable bottom fixing node 4; the single-tube tower cantilever beam node 5 is set on the single-tube tower body 1; the middle part of the cable 2 is fixed by the single-tube tower cantilever beam node 5.

[0035] Cable 2 is a steel cable 2.

[0036] In this embodiment, the single-tube tower cantilever beam node 5 includes 6 evenly distributed cantilever beams; the cantilever beams are connected to the single-tube tower body 1 through the second clamp 7.

[0037] In this embodiment, there are 6 cables 2.

[0038] In this embodiment, the top fixing node 3 of the cable includes a node plate with reserved bolt holes; the number of nodes is the same as that of the cantilever beams and they are arranged in parallel in a one-to-one correspondence.

[0039] The upper end of the cable 2 is fixed to the tower body 1 of the single-tube tower through the cable top fixing node 3; the cable top fixing node 3 is connected to the tower body 1 of the single-tube tower through the first clamp 6.

[0040] In this embodiment, the bottom fixing node 4 of the cable includes chemical anchors; the lower end of the cable 2 is fixed to the foundation platform of the monotube tower by chemical anchors; the bottom fixing node 4 of the cable includes helical piles; the lower end of the cable 2 is fixed to the perimeter of the monotube tower foundation by helical piles. In this embodiment, the angle between the straight line determined by the cantilever beam node 5 of the monotube tower and the bottom fixing node 4 of the cable and the center line of the monotube tower body 1 is 30 degrees, which is used to increase the horizontal component of the tension of the cable 2, thereby increasing the reinforcement effect.

[0041] The cantilever beam node 5 of the single-tube tower is set at 15m on the tower body 1 of the single-tube tower.

[0042] The top fixing node 3 of the cable is set above the node 5 of the cantilever beam of the single-tube tower; the top fixing node 3 of the cable is set 1.5 meters above the node 5 of the cantilever beam of the single-tube tower.

[0043] The specific reinforcement method and principle are as follows: As the number of antennas or other equipment mounted on the top of the monotube tower continues to increase, the wind load borne by the monotube tower also increases, which may cause the tower top displacement and the tower body strength to exceed the specifications. This can be addressed by arranging hyperbolic paraboloid-shaped cables 2 on the tower body 1 for reinforcement. Several cantilever beam nodes 5 are set on the tower body 1, with corresponding additions of several cable bottom fixing nodes 4 and cable top fixing nodes 3. Cables 2 are installed between these nodes for reinforcement. The angle between the cables 2 and the tower body 1 increases the horizontal component of the cable tension, thereby improving the reinforcement effect. The cantilever beam nodes 5 and cable top fixing nodes 3 should be connected to the tower body 1 via clamps. Since monotube towers are generally narrower at the top and wider at the bottom, and when wind loads act on the tower, the force on the upper nodes is downward in the vertical direction, thus ensuring the force transmission between the nodes and the tower body. Meanwhile, since the forces on the upper and lower cables 2 can be canceled out in the vertical direction, the cantilever beam is mainly subjected to compressive forces, and the cross-section of the cantilever beam can be greatly reduced.

[0044] Comparative Example

[0045] like Figure 3 As shown in the comparative example, this invention provides a traditional single-tube tower reinforcement device, which adopts the traditional guy wire reinforcement method. The traditional single-tube tower reinforcement device includes a guy cable 2, the upper end of which is fixed to a third clamp 9 provided on the single-tube tower body 1, and the lower end of which is fixed to a fourth clamp 10. The fourth clamp 10 is fixed to the foundation platform by chemical bolts 8.

[0046] Traditional single-tube tower reinforcement devices, as illustrated in the comparison, have high site requirements, needing reliable fixed nodes nearby. Furthermore, their reinforcement effect on tower stiffness is insufficient when the cable angle is small, and a large site is required to achieve a good reinforcement effect. In contrast, the single-tube tower reinforcement device in this embodiment has the following advantages: 1. Lower reinforcement cost; 2. Smaller reinforcement footprint; 3. Simpler reinforcement method with high operability; 4. Significant reinforcement effect on the overall stiffness of the single-tube tower; 5. Better aesthetics.

It will be apparent to those skilled in the art that various modifications can be made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort.
