Description

Technical Field

[0001] The present invention specifically relates to a reinforcement device and an implementation method for improving the stability performance of single-angle steel members of transmission towers. Background Art

[0002] As an important infrastructure for power transmission, transmission towers are long-term exposed to the erosion of the natural environment and various load effects. Single-angle steel members are key components of transmission towers. In actual operation, due to the structural characteristics of single-angle steel members, their stability performance is easily affected. For example, in severe weather conditions such as strong winds and earthquakes, single-angle steel members may deform, become unstable, etc., thus affecting the safety and reliability of the entire transmission tower.

[0003] At present, there are many deficiencies in the reinforcement methods for single-angle steel members of transmission towers. Some traditional reinforcement methods add auxiliary components by welding or bolt connection, etc., but this method may cause damage to the original components, and the construction process is relatively complex, with high technical requirements for construction personnel. At the same time, the durability of some reinforcement devices is poor, and they cannot effectively improve the stability performance of single-angle steel members for a long time, making it difficult to meet the requirements of long-term stable operation of transmission towers. Therefore, it is of great practical significance to develop an efficient, reliable and simple-to-construct reinforcement device and implementation method for improving the stability performance of single-angle steel members of transmission towers. Summary of the Invention

[0004] In the prior art, there are many deficiencies in the reinforcement methods for single-angle steel members of transmission towers: traditional reinforcement methods add auxiliary components by welding or bolt connection, etc., which may cause damage to the original components, and the construction process is complex, with high technical requirements for construction personnel; the durability of some reinforcement devices is poor, and they cannot effectively improve the stability performance of single-angle steel members for a long time, making it difficult to meet the requirements of long-term stable operation of transmission towers.

[0005] The purpose of the present invention is to provide a reinforcement device and an implementation method for improving the stability performance of single-angle steel members of transmission towers, so as to solve the problems of poor reinforcement effect, complex construction and poor durability of single-angle steel members existing in the prior art.

[0006] Technical Solution

[0007] The reinforcement device of the present invention includes a single-angle steel member, reinforcement auxiliary materials, an outer sleeve reinforcement member, vulcanized rubber, steel strands, a steel strand deflector and a steel strand clamp. The reinforcement auxiliary materials are matched with the inner side of the single-angle steel member, and the outer sleeve reinforcement member is sleeved on the outside of the single-angle steel member and the reinforcement auxiliary materials. The vulcanized rubber is arranged at the gaps or defects at the joints of each component, used to fill the gaps and play a buffering and shock-absorbing role. The steel strands are tensioned on both the inside and outside by a light jack, a steel strand deflector is used at the outer corner of the single-angle steel member, and after tensioning, it is fixed with a steel strand clamp.

[0008] Based on the above technical solutions, the following further optimizations are made:

[0009] 1. The single-angle steel member and the reinforcement auxiliary materials are tightly connected through an outer reinforcement member. There is also a rubber connector on the outer side of the single-angle steel member, and its thickness is the same as that of the outer reinforcement member.

[0010] 2. The shape of the outer reinforcement member is adapted to the shape of the angle steel member. The material is high-strength alloy steel, and the thickness is [4 - 8] mm. The thickness range of the vulcanized rubber on the inner side of the outer reinforcement member is [1 - 3] mm.

[0011] 3. The material of the vulcanized rubber is selected from one or more of chloroprene rubber, nitrile rubber, or polyurethane rubber.

[0012] 4. The diameter of the steel strand is Φ[4 - 8] mm; the clamping force of the steel strand clamp is not less than the tensile force of the steel strand.

[0013] The selection of rubber hardness

[0014] The rubber hardness for connecting with steel is usually determined according to specific usage requirements and working conditions. Generally, it is more common to be between Shore A hardness of [40 - 90] degrees. In the present invention, the selection of the hardness of the vulcanized rubber needs to comprehensively consider the following factors:

[0015] 1. Buffering and shock absorption: During the operation of the transmission tower, the single-angle steel member may be impacted by external forces such as wind and earthquake. The rubber needs to have good elasticity to absorb vibration energy. Therefore, for shock absorption and buffering purposes, the rubber hardness is generally more suitable to be between Shore A [40 - 60] degrees. A lower hardness allows the rubber to generate a larger deformation when vibrating, thus effectively buffering the impact force and protecting the single-angle steel member from damage.

[0016] 2. Sealing performance: At the connection part of the reinforcement device, to ensure good sealing effect and prevent moisture, corrosive gases, etc. from entering the interior, the rubber hardness is usually around Shore A [60 - 80] degrees. If the hardness is too low, the rubber is easily extruded from the sealing gap and cannot achieve effective sealing; if the hardness is too high, it is difficult to adapt to the small deformation of the sealing surface, which will also affect the sealing performance.

[0017] 3. Long-term stability: To ensure that the reinforcement device can effectively improve the stability performance of the single-angle steel member for a long time, the rubber needs to have a certain hardness to maintain the structural stability. Usually, the hardness is around Shore A [70 - 90] degrees. A higher hardness can reduce the deformation of the rubber during long-term use and improve the long-term reliability of the device.

[0018] In practical applications, factors such as the connection method between rubber and steel, the temperature, humidity, and chemical media of the working environment also need to be considered for their impact on the hardness of rubber. For example, in a high-temperature environment, rubber will become soft, and in this case, rubber with a relatively high initial hardness may need to be selected; in an environment with chemical corrosive media, the hardness of rubber may also change, and it is necessary to select a suitable rubber material resistant to chemical corrosion and adjust the hardness to ensure that the reinforcement device can perform well under different working conditions.

[0019] Compared with the prior art, the advantages of the present invention are

[0020] 1. Enhanced stability: Through the cooperation of the outer sleeve reinforcement and the reinforcement auxiliary material, the overall stability of the single-angle steel member is effectively enhanced, and its load-bearing capacity is improved.

[0021] 2. Buffering and shock absorption: The use of vulcanized rubber can not only fill the gaps and defects at the joints of various components but also play a role in buffering and shock absorption, improving the durability of the device.

[0022] 3. Efficient tensioning: The tensioning of the steel strand can further improve the stability performance of the single-angle steel member, and through the setting of the steel strand deflector and the steel strand clamp, the arrangement and fixation of the steel strand are more convenient and reliable.

[0023] 4. Simple construction: The implementation method steps of the present invention are clear and simple, easy to operate, and cause less damage to the original member during construction. At the same time, through various inspections and tests, it can ensure that the reinforcement effect meets the design requirements. Description of the Drawings
