Description

A steel structure connection structure for power transmission towers Technical Field

[0001] This invention relates to the field of steel structure connection technology, and in particular to a steel structure connection structure for power transmission towers. Background Technology

[0002] As a crucial supporting structure for power transmission lines, the safety, stability, and durability of power transmission towers directly affect the reliable operation and long-term service capability of the power grid. Steel structures, due to their high strength, light weight, and short construction period, are widely used in power transmission towers. Therefore, there is a need to design a steel structure connection structure for power transmission towers. To this end, patent CN219993301U discloses a steel structure connection device for power transmission towers, including a steel structure main body and a connection mechanism. The steel structure main body includes four sets of vertical support steels, several sets of first support steels disposed inside the vertical support steels, and second support steels disposed on one side of the first support steels. The connection mechanism includes several sets of connectors fixed to the inner wall of the vertical support steels and several sets of connecting rods detachably installed on the vertical support steels. This invention discloses a steel structure connection device for power transmission towers. Through the arrangement of a steel structure main body, a connection mechanism, and a reinforcement mechanism, the connecting parts, first support steel, and second support steel cooperate to connect the vertical support steel. The connecting rod and threaded block cooperate to improve the connection strength of the connecting parts. The reinforcement connecting steel, reinforcement parts, and threaded rod improve the overall stability of the steel structure main body, facilitating user convenience. While the aforementioned steel structure connection device for power transmission towers can improve connection stability through reinforcement parts, its bottom connection point with the ground is susceptible to ground subsidence. Therefore, a steel structure connection structure for power transmission towers needs to be designed. Summary of the Invention

[0003] The purpose of this invention is to provide a steel structure connection structure for power transmission towers, which solves the defect that the bottom of the existing steel structure connection structure for power transmission towers is easily affected by ground subsidence.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a steel structure connection structure for power transmission towers, including a base; reinforcing plates are uniformly fixed on the outer walls of both sides of the bottom of the base; an anchoring structure is fixed at the bottom end of the base; the anchoring structure includes a base plate fixed to the bottom end of the base; an anchor point seat is fixed at the bottom end of the base plate; and anchor blocks are uniformly fixed at the edge of the bottom end of the base plate; connecting mechanisms are uniformly fixed on the outer walls of both sides of the top of the base; a steel structure body is provided above the base; and a limit structure is fixed on the side of the base away from the connecting mechanism.

[0005] Preferably, the reinforcing plates are symmetrically distributed on both sides of the base, and the reinforcing plates are evenly spaced on one side of the base.

[0006] Preferably, the anchor blocks are evenly distributed at the bottom end of the base plate.

[0007] Preferably, the connecting mechanism includes a first connecting plate, a second connecting plate, and connecting bolts. The first connecting plate is evenly fixed to both sides of the top of the base, and the second connecting plate is fixed to the outer walls of both sides of the steel structure body. Connecting bolts are evenly inserted through the top of the first connecting plate.

[0008] Preferably, the first connecting plate is symmetrically distributed on both sides of the base, and the second connecting plate is symmetrically distributed on both sides of the steel structure body.

[0009] Preferably, the first connecting plate and the second connecting plate are fixedly connected by connecting bolts, and the connecting bolts are evenly distributed on the top of the first connecting plate.

[0010] Preferably, the limiting structure includes an upper limiting frame, a lower limiting frame, and limiting bolts. The upper limiting frame is fixed to the outer walls on both sides of the bottom of the steel structure body, and the lower limiting frame is fixed to the outer walls on both sides of the top of the base. The bottom of the upper limiting frame is penetrated by limiting bolts.

[0011] Preferably, the upper limit frame is symmetrically distributed on both sides of the steel structure body, and the lower limit frame is symmetrically distributed on both sides of the base.

[0012] Preferably, the bottom ends of the limiting bolts all extend to the outside of the lower limiting frame.

[0013] The present invention provides a steel structure connection structure for power transmission towers, which has the following advantages: By incorporating an anchoring structure, the anchor blocks and anchor seats are cast into the foundation at the installation point using concrete, improving the stability of the entire connection assembly during daily use. The structure is evenly distributed, effectively distributing stress and preventing loosening or displacement due to wind, vibration, or load changes. This achieves a convenient and stable connection, enhancing the stability of the steel structure connection structure for power transmission towers during use. Furthermore, the invention includes a connection mechanism responsible for connecting the base to the steel structure body, through symmetrically distributed first and second connecting plates. The plates and connecting bolts enable quick and secure assembly. Their design facilitates on-site installation and disassembly while ensuring uniform stress distribution at the connection points. This design facilitates rapid connection and improves the ease of use of the steel structure connection structure for power transmission towers. By incorporating limiting structures—the upper connecting plate limit frame, the lower connecting plate limit frame, and the limiting pins and bolts—the relative displacement between the steel structure body and the base is restricted, preventing lateral sliding or torsion under wind vibration or load changes. This design facilitates the restriction of the base and steel structure body, enhancing the stability of the steel structure connection structure for power transmission towers during use.

Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please refer to Figures 1-6. The present invention provides a steel structure connection structure for power transmission towers, including a base 1.

[0018] Referring to Figures 1-6, reinforcing plates 2 are uniformly fixed on the outer walls of both sides of the bottom of the base 1. The reinforcing plates 2 are symmetrically distributed on both sides of the base 1 and are evenly distributed on one side of the base 1. An anchoring structure 3 is fixed at the bottom end of the base 1. The anchoring structure 3 includes a base plate 31 fixed to the bottom end of the base 1. An anchor point seat 33 is fixed at the bottom end of the base plate 31. Anchor point blocks 32 are uniformly fixed at the edge of the bottom end of the base plate 31 and are evenly distributed at the bottom end of the base plate 31.

[0019] The base plate 31 is fixed to the bottom of the base 1. The anchor blocks 32, which are evenly distributed along the edge, provide multi-point support, increasing the contact area and friction. The anchor seat 33 serves as the central support point, further enhancing the overall rigidity and anti-overturning ability of the structure. By embedding the anchor blocks 32 and anchor seats 33 into the reserved trench and fixing them with concrete, the overall installation stability can be improved.

[0020] Referring to Figures 1-6, connecting mechanisms 4 are uniformly fixed on the outer walls of the top two sides of the base 1. The connecting mechanism 4 includes a first connecting plate 41, a second connecting plate 42, and connecting bolts 43. The first connecting plate 41 is uniformly fixed on both sides of the top of the base 1, and the second connecting plate 42 is fixed on the outer walls of both sides of the steel structure body 5. Connecting bolts 43 are uniformly penetrating the top of the first connecting plate 41. The first connecting plate 41 is symmetrically distributed on both sides of the base 1, and the second connecting plate 42 is symmetrically distributed on both sides of the steel structure body 5. The first connecting plate 41 and the second connecting plate 42 are fixedly connected by connecting bolts 43. The connecting bolts 43 are evenly distributed on the top of the first connecting plate 41. The steel structure body 5 is set above the base 1.

[0021] The first connecting plate 41 is fixed to the top two sides of the base 1, and the second connecting plate 42 is fixed to the two sides of the steel structure body 5. The two are connected and fastened by the connecting bolts 43 to form a rigid connection. The symmetrically distributed and equally spaced limiting bolts 63 ensure that the connection surface is subjected to uniform force, prevent stress concentration, and improve the safety and durability of the overall structure.

[0022] Referring to Figures 1, 2, 5, and 6, a limiting structure 6 is fixed on the side of the base 1 away from the connecting mechanism 4. The limiting structure 6 includes an upper limiting frame 61, a lower limiting frame 62, and a limiting bolt 63. The upper limiting frame 61 is fixed to the outer walls on both sides of the bottom of the steel structure body 5, and the lower limiting frame 62 is fixed to the outer walls on both sides of the top of the base 1. The bottom of the upper limiting frame 61 is penetrated by the limiting bolt 63. The upper limiting frame 61 is symmetrically distributed on both sides of the steel structure body 5, and the lower limiting frame 62 is symmetrically distributed on both sides of the base 1.

[0023] The limiting bolt 63 passes through the upper limiting frame 61 and extends to the outside of the lower limiting frame 62, forming a mechanical limit. The symmetrical distribution design ensures that the forces on both sides are balanced and effectively resists lateral forces. This structure enhances the shear and torsional resistance of the overall structure without affecting the vertical load-bearing capacity.

[0024] Although the present invention 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, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
