本图系配合专业设计院编制的专电009和专电0010两套架空线路木电杆的木质主杆而设计的钢筋混凝土腿柱。为了减轻重量,腿柱的中间是空心的(空心圆直径为φ120毫米),长度为4米和5米两种,断面为240×210毫米。其允许弯矩分别为1.8吨米和2.9吨米。
The figure is designed with the professional design institute of the electric 009 and the electric 0010 two sets of overhead poles wood wooden poles and design of reinforced concrete legs. In order to reduce weight, the middle of the legs are hollow (hollow circle diameter of φ120 mm), the length of 4 meters and 5 meters two, section 240 × 210 mm. The allowable bending moment is 1.8 tons and 2.9 tons respectively.
