Composite hollow interlayer concrete-filled steel tube pole and preparation method thereof
The invention belongs to the technical field of building construction, and particularly provides a composite hollow interlayer concrete-filled steel tube pole and a preparation method thereof. The structure is composed of nested inner and outer wall steel pipes, the inner and outer wall steel pipes are welded by flanges, an interlayer between the inner and outer wall steel pipes is filled with lightweight concrete, and the lightweight concrete comprises the following components by weight: 1000-1400 parts of coarse aggregate, 700-900 parts of fine aggregate, 600-800 parts of a cementing material, 100-200 parts of an active admixture, 140-250 parts of water and 7-20 parts of a water reducing agent. The problems that in the prior art, composite high-strength hollow interlayer concrete-filledsteel tube cast-in-place wastes time and labor, efficiency is low, the environment is polluted, and the dead weight of an electric pole is large are solved.
本公开属于建筑施工技术领域，具体提供一种复合中空夹层钢管混凝土电杆及其制备方法。其结构为嵌套的内外壁钢管，所述内外壁钢管用法兰焊接，在内外壁钢管中间的夹层填充轻质混凝土，所述轻质混凝土包括按重量份数的粗骨料1000～1400份，细骨料700～900份，胶凝材料600～800份，活性掺合料100～200份，水140～250份，减水剂7～20份。解决现有技术中复合高强中空夹层钢管混凝土现场浇筑费时费力，且效率较低污染环境，以及电杆自重较大的问题。
