CN204475958U 一种用于输电铁塔无填板四组合角钢截面的变坡节点 失效 - 放弃

一种用于输电铁塔无填板四组合角钢截面的变坡节点
摘要：
本实用新型公开了一种用于输电铁塔无填板四组合角钢截面的变坡节点，包括底座板和上下靴板，设置有内包角钢、无填板四组合角钢，所述无填板四组合角钢的端部与下靴板的端部对齐设置，所述无填板四组合角钢、下靴板的外部设置内包角钢，所述内包角钢上段与下靴板连接，所述内包角钢下段与无填板四组合角钢连接，所述内包角钢的安装方向与下部无填板四组合角钢方向一致。本实用新型中的结构，提高变坡节点刚度和安全性的同时，四组合角钢构件勿需设置常规连接方式所需的填板，有效减轻整塔重量、减小焊接工作量、加工便利、施工方便、缩短建设工期，节约工程成本，具有一定经济性。
摘要（英）：

The utility model discloses a variable slope node for the section of power transmission tower four-combination angle steel without a filler plate. The variable slope node comprises a base plate, an upper shoe plate and a lower shoe plate. The variable slope node is provided with inner covering angle steel and the four-combination angle steel without the filler plate. The end portion of the four-combination angle steel without the filler plate is level with the end portion of the lower shoe plate. The outer portion of the four-combination angle steel without the filler plate and the outer portion of the lower shoe plate are provided with the inner covering angle steel. The upper section of the inner covering angle steel is connected with the lower shoe plate. The lower section of the inner covering angle steel is connected with the four-combination angle steel without the filler plate. The installation direction of the inner covering angle steel is identical to the direction of the four-combination angle steel on the lower portion. According to the structure, the rigidity and the safety of the variable slope node are improved, the filler plate needed by a regular connecting mode does not need to be arranged on the four-combination angle steel, and the variable slope node effectively reduces the weight of the whole tower, reduces welding workload, is convenient to process and convenient to construct, shortens construction period, reduced project cost and has certain economic efficiency.
