Stay wire reinforcing method for tower body of self-standing power transmission tower
The invention discloses a reinforcing method for a tower body of a self-standing power transmission tower. The method comprises the steps that the tower body of the power transmission tower is divided into a plurality of intersections, and cross stay wires are arranged on the tower body surfaces of the intersections. According to the reinforcing method, in combination with the deformation characteristic of the self-standing power transmission tower under the action of dynamic loads such as strong wind, the crossed stay wires are selectively arranged on the four planes of the power transmission tower according to the inter-section height and reinforcement requirements of the tower, the roller constraint nodes are arranged at the intersection points of the crossed stay wires, deformation of different layers of the iron tower is effectively controlled by using the stay wires, the local and overall rigidity of the tower body of the power transmission tower structure is improved, the rolling constraint damping and friction damping effects of the rollers are exerted, and vibration energy is rapidly attenuated. Existing rod pieces of an iron tower structure do not need to be disassembled or replaced, the situation that the strength of nodes and the rod pieces of an existing structure is weakened through trepanning and other measures on the tower is avoided, meanwhile, internal force of the iron tower is better distributed, local strength and rigidity are improved, and the damping characteristic under the action of dynamic loads such as strong wind is improved.
本发明公开了一种自立式输电塔塔身加固方法，包括：将输电塔的塔身分成若干节间段，在节间段的塔身面设置交叉拉线。本发明结合自立式输电塔在强风等动荷载作用下的变形特点，在输电塔四个平面上，按照杆塔节间高度及加固需要，有选择地设置交叉拉线，并在交叉拉线的交叉点设置滚轮约束节点，利用拉线有效控制铁塔不同层间的变形，提高输电塔结构的塔身局部和整体刚度，发挥滚轮的滚动约束阻尼和摩擦阻尼作用，迅速衰减振动能量。本发明不需要拆卸、更换铁塔结构现有的杆件，避免在塔上开孔等措施削弱现有结构的节点和杆件强度，同时具有更好地分配铁塔内力，增加局部强度、刚度，提升在强风等动力荷载作用下的阻尼特性。
