Description

Technical Field

[0001] This utility model relates to the field of concrete poles, specifically a ring-shaped prestressed concrete pole with a multi-segment flange connection. Background Technology

[0002] Concrete poles are poles made of concrete and reinforced with steel bars or wires, mainly used for overhead power lines in industries such as power, telecommunications, and railways. Concrete poles can be divided into two types: ordinary reinforced concrete poles and prestressed concrete poles. Ordinary reinforced concrete poles use ordinary steel bars, while prestressed concrete poles use prestressed steel bars, resulting in higher crack resistance and strength.

[0003] In the prior art, such as in the publication number CN205224793U, a concrete pole is disclosed, which includes a first vertical ring, a second vertical ring, a first supporting steel bar and a second supporting steel bar. The first vertical ring and the second vertical ring are arranged in parallel. The first supporting steel bar and the second supporting steel bar are respectively connected to the first vertical ring and the second vertical ring. The two supporting steel bars are connected and fixed to the first vertical ring and the second vertical ring to form an integral support.

[0004] While the aforementioned patent ensures that the erected ring of the concrete pole does not tilt, slant, or collapse after the concrete pole frame is formed, thus guaranteeing the internal structural quality of the concrete pole, the excessive length of the pole body necessitates the overall movement of the pole body during transportation and subsequent construction and installation, leading to inconvenience in installation. Furthermore, the pole body, being a single unit of length, occupies transportation space, and due to its long length and susceptibility to external environmental factors, it is prone to collapse and breakage. Therefore, to address the above problems, a multi-segment flange-connected annular prestressed concrete pole is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, such as excessive pole length leading to the need for overall pole movement during transportation and subsequent installation, which causes installation inconvenience, and the pole's monolithic length occupies transportation space, and its long length and susceptibility to external environmental factors can cause collapse and breakage, this invention proposes a multi-segment flange-connected annular prestressed concrete pole.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A multi-segment flange-connected annular prestressed concrete pole of this utility model includes a pole body A; a connecting mechanism is provided at the top of the pole body A, a pole body B is provided at the top of the connecting mechanism, a connecting plate A is fixedly connected to the bottom of the pole body A, a fixing ring is sleeved on the surface of the bottom of the pole body A, and a number of connecting buckles are fixedly connected in a ring array on the surface of the fixing ring, and one end of the connecting buckle is movably connected to a support mechanism for improving the stability of the pole.

[0007] The connecting mechanism includes an A flange disposed at the top of the A rod. The surface of the A flange is provided with a plurality of threaded holes in a circular array. Each threaded hole is provided with a threaded bolt. One end of the threaded bolt passes through the inside of the threaded hole and is threadedly connected to a B flange. The top of the B flange is fixedly connected to the bottom of the B rod.

[0008] The support mechanism includes a connecting block A movably connected to one end of the connecting buckle. One end of the connecting block A is rotatably connected to a threaded cylinder. The threaded cylinder is internally threaded with a threaded rod, and one end of the threaded rod is provided with a connecting block B.

[0009] Preferably, one end of the B connecting block is fixedly connected to a positioning plate, and the surface of the positioning plate is provided with a plurality of threaded pins for fixing.

[0010] Preferably, the surface of the A connecting plate is arranged in a circular array with a plurality of threaded bolts, and the bottom of the threaded bolts is provided with the B connecting plate.

[0011] Preferably, both rod A and rod B have a number of reinforcing ribs inside to increase the strength of the rod body, and the reinforcing ribs are embedded in the interior of rod A and rod B in a ring array.

[0012] Preferably, both rod A and rod B have interconnected cavities from top to bottom inside, and are circular hollow tubes.

[0013] Preferably, a plurality of reinforcing triangular plates are provided on the top surface of the flange A and between the threaded holes, and the reinforcing triangular plates are arranged in a ring array around the circumference of the rod.

[0014] The advantages of this utility model are:

[0015] 1. This utility model, through the segmented design of the A-pole body and B-pole body and the flange connection mechanism, divides the pole into multiple sections, which can be stacked during transportation, reducing the space occupied. During on-site installation, the threaded holes and threaded bolts of the A-flange and B-flange can be quickly connected, reducing the assembly time of a single section. It solves the industry pain points of traditional concrete poles, such as difficult transportation, slow installation, and easy overturning, and significantly reduces the transportation and hoisting costs of ultra-long poles, achieving a comprehensive upgrade of high strength, lightweight and multi-functionality.

[0016] 2. This utility model adopts a telescopic structure for the threaded cylinder and threaded rod of the support mechanism. The support length can be adjusted by rotating the threaded cylinder. With the help of the threaded pins of the positioning plate driven into the ground, multiple radial ground anchor points are formed, which improves the pole's resistance to crosswinds. It is especially suitable for soft soil or sloping terrain, and realizes adjustable support with prestressing reinforcement to adapt to complex terrain. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1-4As shown, a multi-segment flange-connected annular prestressed concrete pole includes a pole body A 1; a connecting mechanism 2 is provided at the top of the pole body A 1, a pole body B 3 is provided at the top of the connecting mechanism 2, a connecting plate A 4 is fixedly connected to the bottom of the pole body A 1, a fixing ring 5 is sleeved on the surface of the bottom of the pole body A 1, and a number of connecting buckles 6 are fixedly connected in a ring array on the surface of the fixing ring 5. One end of the connecting buckle 6 is movably connected to a support mechanism 7 for improving the stability of the pole. The connecting mechanism 2 includes a flange A 21 provided at the top of the pole body A 1. A number of threaded holes 22 are opened in a ring array on the surface of the flange A 21. A threaded bolt 23 is provided inside each threaded hole 22. One end of the threaded bolt 23 passes through the inside of the threaded hole 22 and is threadedly connected to a flange B 24. The top of the flange B 24 is fixedly connected to the bottom of the pole body B 3.

[0025] During operation, pole A 1 and pole B 3 are connected via flange A 21 and flange B 24. The threaded bolt 9 of connecting plate A 4 is locked to the pre-embedded connecting plate B 10. Pole B 3 is hoisted to the top of pole A 1, aligning flange B 24 with the threaded hole 22 of flange A 21. Threaded bolt A 23 is inserted and manually pre-tightened. A temporary support plate is welded between the reinforcing triangular plate 8 of flange A 21 and flange B 24 to prevent flange deflection during docking. This supports modular segmented transportation, reduces the logistical difficulty of ultra-long poles, and lowers transportation costs.

[0026] Furthermore, the support mechanism 7 includes an A connecting block 71 movably connected to one end of the connecting buckle 6. One end of the A connecting block 71 is rotatably connected to a threaded cylinder 72. The threaded cylinder 72 is internally threaded with a threaded rod 73. One end of the threaded rod 73 is provided with a B connecting block 74. One end of the B connecting block 74 is fixedly connected to a positioning plate 741. The surface of the positioning plate 741 is provided with a plurality of threaded pins 742 for fixing.

[0027] During operation, the threaded cylinder 72 and threaded rod 73 of the support mechanism 7 can be extended and adjusted to adapt to complex terrains such as slopes and soft soil. By adjusting the support length, the verticality deviation of the pole can be reduced. The threaded pins 742 of the positioning plate 741 can penetrate deep into the ground to form multi-point radial anchoring, which can resist lateral tension and prevent the pole from tilting in strong winds. The support height can be adjusted by rotating the threaded cylinder 72. A single person can complete the horizontal calibration of the pole within 5 minutes without the need for heavy machinery assistance.

[0028] Furthermore, the surface of the A connecting plate 4 is arranged in a circular array with several threaded bolts 9, and the bottom of the threaded bolts 9 is provided with the B connecting plate 10;

[0029] During operation, A connecting plate 4 and B connecting plate 10 are clamped together by threaded bolts 9 to disperse the foundation settlement stress, prevent the bottom of the pole from loosening, and improve the compressive strength of the joint. The double-plate design allows the pole to remain vertical even when the foundation settlement is slight (≤5cm), reducing the frequency of later maintenance.

[0030] Furthermore, both rod A 1 and rod B 3 have several reinforcing ribs 11 inside to increase the strength of the rod body. The reinforcing ribs 11 are embedded in the interior of rod A 1 and rod B 3 in a ring array. Both rod A 1 and rod B 3 have interconnected cavities from top to bottom inside, and are circular hollow tubes.

[0031] During operation: The reinforcing ribs 11 of the ring array work together with the hollow tubular structure to improve the bending strength of the pole while reducing its weight, making it easier to erect manually. The cavity of the pole can accommodate cables or optical fibers, realizing the integration of power / communication pole functions and reducing the risk of external cables.

[0032] Furthermore, several reinforcing triangular plates 8 are provided on the top surface of flange A 21 and between the threaded holes 22, and the reinforcing triangular plates 8 are arranged in a ring array around the circumference of the rod body;

[0033] During operation, the reinforced triangular plate 8 evenly distributes the stress at the flange connection to the pole body, improves the torsional strength of the joint, prevents the breakage of the connection of multiple pole sections, and the inclined support structure of the reinforced triangular plate 8 absorbs the seismic shear wave energy to meet the seismic resistance requirements of high intensity areas.

[0034] Working principle: The multi-section pole is divided into individual sections according to the design length, such as pole body A 1, pole body B 3, etc., and laid flat on the transport vehicle for transport to the construction site. Pole body A 1 is vertically hoisted to the installation point and locked to the pre-embedded connecting plate B 10 through the threaded bolt 9 of the connecting plate A 4. A level is used to calibrate and ensure that the verticality error is ≤0.5°. The connecting block 71 of the support mechanism 7 is hinged to the connecting buckle 6 on the fixing ring 5. The threaded cylinder 72 and threaded rod 73 are initially unfolded so that the positioning plate 741 is close to the preset ground anchor point. Pole body B 3 is hoisted to the top of pole body A 1, so that the B flange... Align disc 24 with the threaded hole 22 of flange A 21, insert threaded bolt 23 and manually pre-tighten it. Weld a temporary support plate between the reinforcing triangle plate 8 of flange A 21 and flange B 24 to prevent flange deflection during docking. Use a torque wrench to tighten threaded bolt 23 of flange A to the set torque in diagonal order to ensure that the flange faces fit tightly. Remove the temporary support plate, rotate threaded cylinder 72 to drive threaded rod 73 to extend, so that positioning disc 741 contacts the ground. Continue to rotate until support mechanism 7 is taut. Use an impact drill to drive threaded pin 742 of positioning disc 741 into the ground.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
