Description

Technical Field

[0001] The invention relates to a transmission tower node reinforcement technology, and in particular to a multiple energy dissipation reinforcement device and method for a K-type node of a steel tube tower. Background Art

[0002] During their service, transmission towers are subject to loads such as earthquakes, icing or strong winds, and transmission tower nodes are easily damaged by external forces. Nodes are very important to the safety of transmission towers. Once a node fails, it will not provide sufficient constraints, causing damage to the structural system.

[0003] At present, the node reinforcement measures of transmission towers mainly involve installing reinforcement devices at important nodes of transmission towers to improve the bearing capacity of important nodes. However, the main materials at important nodes of transmission towers are also prone to local buckling due to insufficient bearing capacity. Traditional node reinforcement measures only install reinforcement devices at important nodes, which cannot provide overall reinforcement support and have poor protection capabilities.

Thereby improving the bearing capacity and stability of the original main material and the steel pipe tower node. Under the action of earthquake or extreme load, the energy absorber will be involved in the work, and the friction resistance generated by the rubber slider and the inner wall of the second energy absorber sleeve and the spring and soft steel rod will be used to realize energy dissipation. When the annular plate on the upper reinforced telescopic plate and the annular plate on the lower reinforced telescopic plate suddenly deform slightly, the force can be transmitted to the upper reinforced telescopic plate main board and the lower reinforced telescopic plate main board and then to the ribbed plate (which has great rigidity and is not easy to be damaged). Then the spring works to reset it, which plays the role of energy dissipation buffer.

Compared with the prior art, it not only enhances the node bearing capacity but also enhances the bearing capacity of the main material. The present invention can play the role of energy dissipation buffer in earthquakes or extreme loads, and can effectively improve the node bearing capacity and overall stability of the transmission tower. The present invention does not require temporary disassembly of the original load-bearing components, avoids complex stress redistribution in local areas, and has the advantages of simple structure, convenient maintenance, and obvious effect.

[0063] The working principle of this embodiment is:

[0064] When the original main material 1 is subjected to lateral tension or pressure, for the cross section of the main material, adding this reinforcement device can effectively disperse the stress on the original main material 1 to the reinforcement sleeve 2-1 without annular plate and the reinforcement sleeve 2-2 with annular plate. For the weak section of the original main material 1, the stress can be effectively dispersed to the reinforcement sleeve 2-1 without annular plate and the reinforcement sleeve 2-2 with annular plate and the connecting rod 3, thereby reducing the stress on the original main material 1 and preventing the original main material from buckling. For the corresponding annular plate 5 to be reinforced, adding this reinforcement device can effectively disperse the stress of the annular plate to be reinforced to the reinforced annular plate 4 and the annular plate with the annular plate reinforcement sleeve 2-2 and the annular plate reinforcement sleeve 6-1 and the lower reinforcement telescopic plate 6-2. Thereby improving the bearing capacity and stability of the node between the original main material 1 and the steel pipe tower. Under the action of earthquake or extreme load, the energy absorber 10 will participate in the work, and the friction resistance generated by the rubber slider 10-7 and the inner wall of the second energy absorber sleeve 10-2 and the spring 10-6 and the soft steel rod 10-4 will be used to realize energy consumption. When the annular plate 6-1-1 on the upper reinforced telescopic plate and the annular plate 6-2-1 on the lower reinforced telescopic plate of the reinforced telescopic plate suddenly deform slightly, the force can be transmitted to the upper reinforced telescopic plate main board 6-1-2 and the lower reinforced telescopic plate main board 6-2-2 and then to the ribbed plate 8 (which has great rigidity and is not easily damaged), and then the spring 10-6 works to reset it, which plays the role of energy consumption buffer.

[0065] The device has a reasonable structural design. Compared with the existing technology, it not only enhances the bearing capacity of the nodes but also enhances the bearing capacity of the main material.

[0066] The device acts as an energy buffer under earthquakes or extreme loads, and can effectively improve the bearing capacity and overall stability of transmission tower nodes.

[0067] The device does not require temporary disassembly of the original load-bearing components, thus avoiding complex stress redistribution in local areas, and has the advantages of simple structure, easy maintenance and obvious effect.
