Description

Technical Field

[0001] The present invention relates to the technical field of transmission towers, and in particular to a transmission tower node connection structure and a use method thereof. Background Art

[0002] Transmission towers are fixed buildings that support cables and are generally steel structures. Common transmission towers mainly use two types of tower structures: angle steel and steel pipes. They include multiple main materials that are erected and distributed in a ring around the center line of the transmission tower. The distance between the main materials gradually decreases from bottom to top, and the main materials are connected by crossbars and diagonal materials, thus forming a tower structure that is larger at the bottom and smaller at the top. The safety and reliability of the tower are related to the safe operation of the entire transmission line. When the tower is subjected to wind loads and horizontal tension of the conductor, the overall destruction of the tower structure is very likely to occur due to the buckling of the diagonal materials. The mechanical properties of the main and diagonal rods themselves and the mechanical properties of the rod connection nodes are related to the structural stability and safety of the entire transmission tower. Due to the large number of components and complex stress of the tower structure, very high requirements are placed on the connection nodes. The force transmission mechanism of the node is related to the stress characteristics of the entire pole. In the prior art, the main material and the diagonal material are generally connected by a single-leg angle steel. This type of node connection has an eccentric stress state and its reliability is insufficient in certain scenarios with higher requirements, resulting in insufficient bearing capacity and stability of the main material and the diagonal material.

Here, the secondary angle steel can be stably installed and fixed with the main steel, improving the stability between the secondary angle steel and the main steel.

[0007] Preferably, the vertical connecting plate is aligned with the No. 2 reserved hole, and a No. 2 bolt is inserted into the No. 2 reserved hole. Here, the vertical connecting plate can be stably docked and fixed with the main steel.

[0008] Preferably, the horizontal connecting plate is aligned with the No. 3 reserved hole, and a No. 3 bolt is inserted into the No. 3 reserved hole. Here, the horizontal connecting plate can be stably butt-jointed and fixed with the secondary angle steel.

[0009] Preferably, the number of the reinforcing angle steels is four groups, and the four groups of reinforcing angle steels are respectively installed at the connection between the main steel and the auxiliary angle steel. Here, it helps to improve the stability between the auxiliary angle steel and the main steel, and at the same time, the connection performance between the main steel and the auxiliary angle steel can be reinforced.
