Description

Technical Field

[0001] This invention relates to the field of communication towers, and more particularly to a communication tower made of polyurethane material. Background Technology

[0002] With the rapid development of next-generation information technologies such as 5G and the Internet of Things, the scale of global communication base station construction continues to expand. As of 2025, my country had more than 3 million 5G base stations, of which about 40% were located in complex areas such as mountainous regions, coastal areas, and high seismic intensity zones. As the core carrier structure of base stations, the reliability, weather resistance, and installation efficiency of communication towers directly affect the coverage quality and operating costs of communication networks.

[0003] However, existing communication tower technology still faces multiple industry pain points, specifically as follows: I. Weather Resistance and Maintenance Challenges of Steel Structure Communication Towers: Over 90% of existing communication towers are made of carbon steel such as Q235 and Q345, whose weather resistance deficiencies are particularly pronounced in complex environments. For example, in coastal high-salt-spray environments, chloride ions can damage the passivation film on the steel structure surface, triggering electrochemical corrosion at rates of 0.1-0.3 mm / year. Taking my country's southeastern coastal region as an example, communication towers require anti-corrosion coating renovation every 3-5 years, with annual anti-corrosion maintenance costs per tower approximately 20,000-30,000 yuan, resulting in national annual anti-corrosion maintenance costs exceeding 10 billion yuan.

[0004] II. Bottlenecks in the Transportation and Installation of Steel Structures: A single section of a steel communication tower typically weighs 1.5-3 tons, posing significant transportation and installation challenges in areas with poor transportation. Remote mountainous areas require transport by mules or helicopters, with transportation costs per tower being 2-3 times higher than in plains areas; for some base stations, the transportation cost even exceeds the cost of the tower itself. Steel tower structures require on-site welding or bolting, resulting in long installation cycles and significant weather-related issues. Welding during the rainy season is prone to porosity defects, while low winter temperatures cause bolt torque reduction, decreasing construction efficiency.

[0005] Third, the seismic performance defects of traditional bases: The seismic performance of communication towers is directly related to the ability to ensure communication during earthquakes, but existing technologies have obvious shortcomings; existing communication towers use rigid anchored bases, relying entirely on the tower's own rigidity to resist seismic loads. When an earthquake occurs, stress concentration is prone to occur at the connection between the tower and the base, leading to tower breakage at the base connection.

[0006] Therefore, there is an urgent need for a communication tower structure with good shock absorption and weather resistance. Summary of the Invention

[0007] The purpose of this invention is to provide a communication tower made of polyurethane material, which solves the problems in the prior art.

[0008] To achieve this objective, the present invention adopts the following technical solution: A polyurethane communication tower, comprising: Foundation, wherein an installation well is provided; The shock-absorbing base is disposed in the installation well of the foundation and is adapted and fixed to the well wall of the foundation; The communication tower is located at the upper end of the shock-absorbing base, and the main structure of the communication tower is assembled in sections from modified polyurethane composite material.

The lower end of the damping spring is housed in the groove of the grooved round block, and the upper end elastically abuts against the lower surface of the shaft arm to provide vertical shock absorption support.

[0011] As a preferred embodiment of the polyurethane material communication tower of the present invention, the shock-absorbing connecting bridge includes a welding block, a positioning guide hole block, a snap-fit ​​connecting plate, a reinforcing column, a connecting bridge column, a damping spring II, and a T-shaped snap-fit ​​groove. The welding block is welded and fixed to the upper surface of the upper platform of the supporting shock-absorbing arm seat. The welding block has a shaped structure. The positioning guide hole block is integrally formed on one side of the upper end of the welding block. The engaging connecting plate is fixedly welded to the upper end of the welding block. The lower end of the reinforcing column is fixedly welded to the welding block, and the upper end is fixedly welded to the lower surface of the engaging connecting plate to reinforce and support the engaging connecting plate. The two ends of the connecting bridge column respectively movably pass through the upper end of the welding block and are inserted into the positioning guide hole block. The two damping springs are sleeved on the connecting bridge column, and their two ends are respectively connected to the side of the welding block. The T-shaped engaging groove is opened on the upper surface of the engaging connecting plate. The bottom of the movable plate seat is provided with a T-shaped locking block, and the T-shaped locking block slides and engages with the T-shaped engaging groove.

[0013] In a preferred embodiment of the polyurethane material communication tower of the present invention, the cross-sectional dimensions of the T-shaped locking groove are matched with the cross-sectional dimensions of the T-shaped locking block.

[0014] As a preferred embodiment of the polyurethane material communication tower of the present invention, the tower body includes a tower base section, a tower middle section and a tower head end. The tower base section, tower middle section and tower head end are formed in sections by modified polyurethane composite material and connected by flange bolts.

[0015] As a preferred embodiment of the polyurethane material communication tower of the present invention, a connecting plate one and a connecting plate two are provided on the outer side of the middle section of the tower for connecting the auxiliary support foot.

In mountainous and hilly areas with inconvenient transportation, it can be transported by small trucks or even manually, reducing the transportation cost per tower compared to steel structures. In remote mountainous areas, there is no need to rely on helicopter hoisting, directly solving the shortcomings of existing steel structure towers in terms of difficult and costly transportation. At the same time, polyurethane material itself has excellent acid and alkali resistance, salt spray resistance, and UV resistance, far superior to the corrosion resistance of steel structures. 2. The shock-absorbing arm seat attenuates seismic wave energy through the hinge rotation of the shaft-connected arm and the elastic deformation of the first damping spring.

On the mountain slope foundation, the horizontal component of the triangular support can effectively offset the slope sliding force, and the overturning resistance of the tower body is improved.

[0029] In some embodiments of the present invention, reference is made to... Figure 5-8 As shown, the shock-absorbing connecting bridge 223 includes a welding block 223a, a positioning guide hole block 223b, a snap-fit ​​connecting plate 223c, a reinforcing column 223d, a connecting bridge column 223e, a damping spring 223f, and a T-shaped snap-fit ​​groove 223g; The welding block 223a is welded and fixed to the upper surface of the upper platform plate 222f of the supporting shock-absorbing arm seat 222. The welding block 223a has an L-shaped structure. The positioning guide hole block 223b is integrally formed on one side of the upper end of the welding block 223a.

[0030] Furthermore, the diameter of the connecting bridge post 223e matches the inner diameter of the positioning guide hole block 223b.

[0031] Furthermore, the cross-sectional dimensions of the T-shaped locking groove 223g are matched with the cross-sectional dimensions of the T-shaped locking block 224a.

[0032] The shock-absorbing arm 222 attenuates seismic wave energy through the hinge rotation of the shaft connecting arm 222e and the elastic deformation of the damping spring 222d. When an earthquake occurs, the shaft connecting arm 222e rotates with the vertical load, and the damping spring 222d absorbs the impact energy through compression and rebound, avoiding the stress concentration problem of the rigid base; the T-shaped locking groove 223g of the shock-absorbing connecting bridge 223 slides with the T-shaped locking strip 224a, and the damping spring 223f absorbs seismic wave energy through elastic deformation; compared with the defects of traditional single-stage shock-absorbing bases, the two-stage composite shock absorption of the present invention can attenuate seismic wave components simultaneously, improving the shock absorption efficiency.

[0033] In some embodiments of the present invention, reference is made to... Figure 9-11 As shown, the tower body component 310 includes a tower base section 311, a tower middle section 312, and a tower head end 313. The tower base section 311, the tower middle section 312, and the tower head end 313 are formed in sections by modified polyurethane composite material and then connected by flange bolts. The inner sidewall of the tower body component 310 is integrally formed with a ladder 301.

[0034] The communication tower section 300 uses segmented flange bolt connections, and each section of the tower body 310 has been pre-assembled before leaving the factory. On-site installation can be completed simply by tightening the bolts, which solves the problem of slow installation of existing steel structure towers.

[0035] The ladder 301 is integrally molded into the inner wall of the tower body component 310, with a step spacing of 300mm and anti-slip texture, allowing maintenance personnel to quickly reach the top of the tower 313. Furthermore, a connecting plate 302 and a connecting plate 303 are provided on the outer side of the middle section 312 of the tower for connecting the auxiliary support foot 320.

[0036] Furthermore, the auxiliary support member 320 includes a first supporting angle steel 321, a second supporting angle steel 322, a lower triangular reinforcing frame 323, and an upper triangular reinforcing frame 324; The upper ends of the supporting angle steel 321 and the supporting angle steel 322 are bolted to the outer wall of the middle section 312 of the tower through the connecting plate 302, and the lower ends are anchored to the foundation 100. The two ends of the lower triangular reinforcement frame 323 are bolted to the supporting angle steel 321 and the supporting angle steel 322 respectively, and the other end is connected to the connecting plate 303. The two ends of the upper triangular reinforcement frame 324 are bolted to the supporting angle steel 321 and the supporting angle steel 322 respectively, and the other end is connected to the connecting plate 303 to form a triangular stable support structure.

[0037] The auxiliary support member 320 has its first support angle steel 321 and second support angle steel 322 connected to the tower body member 310. Together with the lower triangular reinforcement frame 323 and the upper triangular reinforcement frame 324, they form a multi-directional stability system. The lower ends of the first support angle steel 321 and second support angle steel 322 are fixed by anchor bolts with a certain embedment depth. Combined with the concrete pouring of the foundation 100, it can resist the foundation slippage caused by rainstorm erosion. On the mountain slope foundation, the horizontal component of the triangular support can effectively offset the slope sliding force, and the tower body's anti-overturning resistance is improved.

[0038] As a preferred option, the modified polyurethane composite material contains glass fiber or carbon fiber reinforcing filler to improve the tensile strength and wind load resistance of the communication tower section 300.

[0039] The main body of the communication tower (section 300) is made of modified polyurethane composite material, with a density only one-quarter that of steel structures, reducing the weight of a single tower section. In mountainous and hilly areas with inconvenient transportation, it can be transported by small trucks or even manually, reducing the transportation cost per tower compared to steel structures. In remote mountainous areas, it eliminates the need for helicopter hoisting, directly solving the problems of difficult and costly transportation of existing steel structure towers. Furthermore, polyurethane material itself has excellent resistance to acids and alkalis, salt spray, and ultraviolet radiation, far superior to the corrosion resistance of steel structures. In coastal high-salt-spray environments, traditional steel structure towers require anti-corrosion coating renovation every 3-5 years, resulting in high annual maintenance costs per tower. In contrast, the communication tower of this invention does not require regular anti-corrosion maintenance, extending its service life and reducing the overall life-cycle maintenance cost, thus solving the problems of expensive maintenance and short lifespan caused by steel structure corrosion.

[0040] Working principle: The foundation 100 forms a stable load-bearing base through concrete pouring. The installation well 110 provides precise installation space for the damping base 200, ensuring a rigid connection between the damping structure and the foundation and preventing overall overturning. The damping base 200 is located within the installation well 110 of the foundation 100, bearing the weight of the communication tower 300 above, and attenuating and dissipating vertical and horizontal loads from earthquakes and strong winds through the damping structure. The communication tower 300 is made of modified polyurethane composite material, combining lightweight and high strength characteristics. The auxiliary support 320 transfers the lateral loads of the tower to the foundation 100 through a triangular stabilizing structure, further improving the overall wind resistance and overturning resistance.

[0041] When external loads such as seismic waves and strong winds act on the tower, the first stage of load attenuation is achieved by the damping base 200, and the second stage of load dispersion is achieved by the self-rigidity of the communication tower 300 and the supporting rigidity of the auxiliary support 320, ultimately achieving stable operation of the tower.

[0042] The damping base 200 consists of a reinforcing base 210 and two-stage damping platforms 220. The reinforcing base 210 is responsible for uniformly transferring the load of the damping structure to the foundation 100. The supporting damping arm 222 of the two-stage damping platform 220 is responsible for vertical damping, and the damping connecting bridge 223 is responsible for horizontal damping. The two work together to achieve omnidirectional load attenuation.

[0043] The shock-absorbing arm 222 dissipates the vibration energy of seismic waves through a hinged structure and a damping spring 222d. The weight and impact loads of the communication tower 300, such as seismic waves and strong winds, are transmitted to the shock-absorbing connecting bridge 223 via the movable plate 224, and then to the upper platform 222f of the shock-absorbing arm 222.

[0044] When the upper plate 222f is subjected to a load, it drives the shaft arm 222e, which is axially connected to it, to move. The lower end of the shaft arm 222e is axially connected to the shaft end 222b of the base plate 222a, forming a rotatable hinge structure. When the load is downward, the shaft arm 222e rotates downward with the shaft end 222b as the fulcrum. This hinge structure replaces the traditional rigid connection, avoiding stress concentration caused by direct load transmission. A damping spring 222d is pre-installed in the grooved circular block 222c at the center of the upper surface of the base plate 222a. The upper end of the spring elastically abuts against the lower surface of the shaft arm 222e, and initially maintains a pre-compression of 10%-15%. When the shaft arm 222e rotates inward and downward, it compresses the damping spring 222d, further compressing the spring and converting mechanical energy into elastic potential energy for storage. At the same time, the internal resistance of the damping spring consumes some energy, which is converted into heat energy and dissipated, achieving the first stage of load attenuation. When the impact load disappears, the damping spring 222d releases its elastic potential energy, pushing the shaft arm 222e to reset, and the upper plate 222f returns to its initial position. During this process, the internal resistance of the spring continues to dissipate the residual vibration energy, preventing the tower from resonating.

[0045] Coordinated vibration reduction with circumferential distribution: The vibration reduction arm 222 is evenly distributed in three groups of 120° circumferentially on the connecting base plate 221. The three groups of structures respond to the load synchronously, ensuring that the upper plate 222f is subjected to uniform force and avoiding vibration reduction failure caused by excessive load on one side.

[0046] The damping connecting bridge 223 attenuates the loads from seismic waves and strong winds through a T-shaped engaging guide and the elastic energy dissipation of the second damping spring 223f. The upper surface of the engaging connecting plate 223c of the damping connecting bridge 223 has a T-shaped engaging groove 223g, which slides in engagement with the T-shaped locking strip 224a at the bottom of the movable plate seat 224. When external loads such as seismic waves or strong winds are generated, the T-shaped locking strip 224a slides along the extension direction of the T-shaped engaging groove 223g. Simultaneously, the shaft connecting arm 222e rotates downwards around the shaft connecting end 222b as a fulcrum. The welded block 223a connected to the upper platform plate 222f of the upper end of the shaft connecting arm 222e moves away, stretching the second damping spring 223f and attenuating the load.

[0047] Damping spring 223f and damping spring 222d form a double-spring damping system, further improving load attenuation efficiency.

[0048] The tower body component 310 of the communication tower section 300 is made of modified polyurethane composite material, which has excellent tensile and bending strength and can withstand the weight of the communication equipment and the lateral thrust of wind loads. The auxiliary support components 320 work together to further improve the stability of the tower body. The tower base section 311, the middle section 312, and the tower head end 313 of the tower body component 310 are connected by flange bolts to form a continuous load-bearing structure. The weight of the communication equipment at the tower head end 313 is transferred from top to bottom to the shock-absorbing base section 200, and then to the foundation 100.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
