Description

Technical Field

[0001] The present application relates to the technical field of communication pole towers, and in particular to an assembled communication pole tower and a communication pole tower structure. Background Art

[0002] With the accelerated advancement of 5G new infrastructure, the communications industry has ushered in new development opportunities. In order to meet the industry's demand for cost reduction and efficiency improvement, various innovative towers and masts have continued to emerge. Concrete communication poles are increasingly used due to their advantages of short construction period and low overall cost.

[0003] In related technologies, the height of concrete communication towers is mainly 20 meters or less, mainly because concrete towers are generally hollow cylindrical or conical structures with a large slenderness ratio. They are prone to large deflections under wind loads and are subject to large bending moments. The horizontal lateral stiffness of the tower is mainly determined by the tower diameter. When the concrete tower is subjected to wind loads or other loads, the large bending moment will cause tensile stress in the tensile zone of the tower, which will cause cracking of the concrete, affecting the structural stiffness and durability. Therefore, the use height of concrete communication towers is limited.

[0004] However, the height requirement for mainstream steel tower mast products in the communications industry is generally 30 to 40 meters. The existing concrete communication poles cannot meet the mounting requirements in most communication scenarios, and their lateral stiffness and crack resistance need to be improved. Summary of the Invention

[0005] The embodiments of the present application provide an assembled communication pole tower and a communication pole tower structure to solve the problem in the related art that the communication pole tower has low lateral stiffness and crack resistance, resulting in height limitation.

[0006] In a first aspect, an assembled communication tower is provided, comprising:

[0007] Multiple tower sections connected from bottom to top, with connecting units provided between each adjacent tower section;

[0009] In some embodiments, the connecting unit includes two connecting flanges and a plurality of fixing bolts;

[0010] The connecting flanges are arranged at corresponding ends of the towers, and a plurality of fixing bolts are arranged at intervals along the circumference of the two connecting flanges and pass through the two connecting flanges in sequence to connect the adjacent towers.

[0011] In some embodiments, the tower barrel includes a cylindrical body, which has a hollow structure and a radial dimension that gradually decreases from bottom to top. A plurality of spaced reinforcing ribs are embedded along the circumference of the cylindrical body, and the reinforcing ribs are connected to the connection unit at the end of the tower barrel.

[0012] In some embodiments, connection threads are provided at both ends of the reinforcing rod, and at least a part of the rod section with the connection threads extends out of the connection unit at the top or bottom, and an anchoring nut matching the connection threads is provided on the extended rod section.

[0013] In some embodiments, a backing plate is also sleeved on the rod section where the connection threads extend, and the backing plate is arranged between the anchoring nut and the corresponding connection unit.

[0014] In some embodiments, the number of the reinforcing rods is even and not less than four;

[0015] A locking collar is sleeved on each anchoring nut, and two cross-set collar connecting rods are provided between adjacent locking collars. The two ends of the collar connecting rod are respectively connected to the adjacent locking collars to limit the rotation of the locking collar.

[0016] In some embodiments, the anchoring nut is a hexagonal nut.

[0022] The beneficial effects brought by the technical solutions provided in this application include:

[0023] An embodiment of the present application provides an assembled communication tower pole. Since multiple sections of tower barrels are connected in sequence from bottom to top, a connection unit is provided between each adjacent tower barrel. At least two reinforcing rods are arranged on the outer side of the tower barrel and are spaced circumferentially along the tower barrel. Each reinforcing rod passes through all connection units and is respectively connected to the connection units at the top and bottom at both ends. Therefore, since the reinforcing rods are arranged axially on the outer side of the tower barrel and sequentially pass through each connection unit, axial pre-compressive stress can be generated in the tower pole concrete, effectively offsetting the tensile stress generated in the tensile zone of the concrete under the action of bending moment, improving the lateral stiffness and crack resistance of the tower pole, reducing the deflection of the tower pole under the action of horizontal load, delaying the cracking of the tower pole concrete, thereby improving the safety and durability of the structure, extending the service life of the structure, and effectively promoting the large-scale application of relatively tall concrete tower poles in the communication industry, reducing costs and increasing efficiency.

Specific Embodiments

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.

[0033] The embodiments of the present application provide a prefabricated communication tower, which can solve the problem of limited height caused by low lateral stiffness and cracking resistance of communication towers in the related art.

[0034] See Figure 1 As shown, the prefabricated communication tower mainly includes multiple sections of tower barrels 1 and strengthening units 3. The tower barrels 1 are precast hollow concrete structures. Multiple sections of the tower barrels 1 are connected in sequence from bottom to top to form a main structure. A connecting unit 2 is provided between each adjacent tower barrel 1. The connecting unit 2 is used to connect and fix the adjacent tower barrels 1. The strengthening unit 3 mainly includes at least two strengthening rods 30. The strengthening rods 30 have a certain length, and the length is close to the height of the main structure but slightly smaller than the height of the main structure. At least two strengthening rods 30 are arranged on the outer side of the tower barrel 1 along the circumferential direction and are spaced along the circumferential direction of the tower barrel 1. Among them, each strengthening rod 30 penetrates through all the connecting units 2 from top to bottom, and the two ends are respectively connected to the connecting units 2 at the top and bottom. On the basis of the connection of the connecting units 2, the strengthening rods 30 further connect and fix multiple sections of the tower barrels 1, enhance the connection strength between multiple sections of the tower barrels 1, and also increase the structural integrity between multiple sections of the tower barrels 1. The strengthening rods 30 enable the concrete of the prefabricated communication tower to generate axial pre-compressive stress, effectively offset the tensile stress generated by the concrete in the tensile zone under the action of the bending moment, improve the lateral stiffness and cracking resistance of the prefabricated communication tower, reduce the deflection of the prefabricated communication tower under the action of the horizontal load, delay the cracking of the concrete, thereby improving the safety and durability of the structure, extending the service life of the structure, and effectively promoting the large-scale application of concrete towers with higher heights in the communication industry, reducing costs and increasing efficiency.

[0035] Further, see Figure 1 and Figure 2As shown, the connection unit 2 specifically includes two connection flanges 20 and a plurality of fixing bolts 21. The connection flanges 20 are arranged at the corresponding ends of the tower barrel 1. The plurality of fixing bolts 21 are arranged at intervals along the circumferences of the two connection flanges 20 and sequentially pass through the two connection flanges 20 for connecting adjacent tower barrels 1. Specifically, connection flanges 20 are provided at the bottom end of the tower barrel 1 at the top and the top end of the tower barrel 1 at the bottom, and connection flanges 20 are provided at both ends of the other tower barrels 1. The connection flanges 20 are disc-shaped, and the outer diameter size of the connection flanges 20 is larger than the outer diameter size of the tower barrel 1 connected thereto, and the outer diameter size changes with the change of the outer diameter size of the tower barrel 1 connected thereto to achieve mutual matching; a plurality of through threaded holes are uniformly spaced along the circumference of the connection flanges 20. When two adjacent tower barrels 1 are connected, the plurality of through threaded holes on the upper and lower connection flanges 20 are aligned one by one, and one fixing bolt 21 is inserted through each group of through threaded holes to connect and fix the two connection flanges 20, thereby realizing the connection and fixation of two adjacent tower barrels 1; at least two through holes are also uniformly spaced along the circumference of the connection flanges 20, and the through holes are arranged in a staggered manner to avoid the through threaded holes, and the through holes are used for passing through the reinforcing rods 30.

[0036] Further, referring to Figure 2 and Figure 5 As shown, the tower barrel 1 mainly includes a barrel body 10. The barrel body 10 is of a hollow structure, and its radial dimension gradually decreases from bottom to top. The height dimensions between the tower barrels 1 can be the same, but the radial dimensions are all different. When multiple tower barrels 1 are connected in sequence, the formed main structure has a gradually decreasing radial dimension from bottom to top; a plurality of spaced reinforcing ribs 11 are embedded along the circumference of the barrel body 10. The reinforcing ribs 11 are mainly used for longitudinal force bearing, and the reinforcing ribs 11 are connected to the connection unit 2 at the end of the tower barrel 1.

[0037] Further, referring to Figure 4 As shown, connection threads 31 are provided at both ends of the reinforcing rod 30, and at least part of the rod section provided with the connection threads 31 extends out of the connection unit 2 at the top or bottom, and an anchoring nut 32 matching the connection threads 31 is provided on the extended rod section. Specifically, connection threads 31 are provided at both ends of the reinforcing rod 30, so it can cooperate with the anchoring nut 32 provided thereon to adjust the tension of the reinforcing rod 30 by adjusting the tightness of the anchoring nut 32; the reinforcing rod 30 is preferably a steel bar, and its quantity can be increased or decreased correspondingly according to the actual size of the tower barrel 1 and actual requirements to ensure that the entire main structure has sufficient lateral stiffness and crack resistance.

[0038] Further, referring to Figure 4As shown, a backing plate 33 is also sleeved on the rod section where the connecting thread 31 extends. The backing plate 33 is arranged between the anchoring nut 32 and the corresponding connecting unit 2 to ensure that the gap between the connecting thread 31 and the corresponding connecting flange 20 is small enough, so as to ensure the connection stability of the reinforcing rod 30. The number of the backing plates 33 can be one or multiple, and can be flexibly adjusted according to the actual connection situation.

[0039] Further, as shown in Figure 3 and Figure 5 As shown, the number of the reinforcing rods 30 is preferably an even number and not less than four, and they are evenly spaced along the circumferential direction of the tower barrel 1. A locking collar 4 is sleeved on each anchoring nut 32, and two cross-shaped collar connecting rods 5 are arranged between adjacent locking collars 4. The two ends of the collar connecting rod 5 are respectively connected to the adjacent locking collars 4 to limit the rotation of the locking collar 4. Specifically, since the reinforcing rod 30 is fixed by the anchoring nut 32, in order to prevent the anchoring nut 32 from loosening, therefore, a locking collar 4 is sleeved on each anchoring nut 32. Since the number of the reinforcing rods 30 is an even number, similarly, the number of the anchoring nuts 32 and the locking collars 4 is also an even number. Every two locking collars 4 form a group, and two cross-shaped collar connecting rods 5 are arranged between each group of locking collars 4. The two collar connecting rods 5 are in a cross structure in the shape of an "8", and the two ends are respectively welded and fixed to the collar connecting rods 5 on the corresponding side. Therefore, if one of the anchoring nuts 32 loosens in the counterclockwise direction, it will drive the adjacent anchoring nut 32 in the same group to rotate in the clockwise direction, and the anchoring nut 32 rotating in the clockwise direction will provide a binding force to prevent the adjacent anchoring nut 32 from loosening counterclockwise, so as to achieve the effect of maintaining the prestress stability.

[0040] Further, the anchoring nut 32 is preferably a hexagonal nut, which is convenient for force application and convenient to adjust the pre-tightening force of the reinforcing rod 30 at any time. The inner hole of the locking collar 4 is also hexagonal and matches the anchoring nut 32.

[0041] Further, as shown in Figure 6As shown, at least two positioning hoop rings 6 are provided along the circumference of the tower barrel 1 at intervals. One end of the positioning hoop ring 6 is connected to the tower barrel 1, and a fixing ring 60 is provided at the other end. The fixing ring 60 is sleeved on one of the reinforcing rods 30. Specifically, since the reinforcing rod 30 is vertically arranged along the axial direction of the main structure and is only fixed to the corresponding connecting flange 20 through the anchoring nuts 32 at the head and tail, in order to ensure the connection strength, therefore, at least two positioning hoop rings 6 are provided along the circumference of each tower barrel 1 at intervals. Preferably, the positioning hoop rings 6 are arranged in the middle of the tower barrel 1. One end of the positioning hoop ring 6 is embedded in the tower barrel 1 for fixation, and the fixing ring 60 provided at the other end is for the reinforcing rod 30 to pass through and be fixed, so as to enhance the connection stability of the reinforcing rod 30.

[0042] Furthermore, in order to extend the service life of the reinforcing rod 30, an anti-corrosion coating is sprayed on the surface of the reinforcing rod 30.

[0043] The present application also provides an assembled communication tower structure, which is characterized in that it includes a foundation 7 and any one of the above-mentioned assembled communication towers. At least a part of the bottom end of the assembled communication tower is buried in the foundation 7 to provide stability through the binding force of the foundation 7.

[0044] Among them, the other structures of the present assembled communication tower structure correspond one by one to the structures of the above-mentioned assembled communication tower, and will not be described repeatedly here.
