Light prefabricated tower mast flange foundation and manufacturing method thereof

QI JINMING / DIAO YANRAO

The invention belongs to the technical field of electric power and communication, and particularly relates to a light prefabricated tower mast flange foundation and a manufacturing method thereof.The light prefabricated tower mast flange foundation comprises a concrete column and a concrete chassis, and is characterized in that the concrete column is in the shape of a circular truncated cone or a quadrangular frustum pyramid, is mainly formed by concrete with main reinforcements and stirrups and is internally provided with a cavity; a metal flange is arranged at the top of the concrete column and mainly composed of a flange plate, a steel plate ring and a rib plate, the steel plate ring wraps the periphery of the top of the concrete column and is welded to an inner hole of the flange plate, and the main rib is connected with the metal flange. According to the light prefabricated tower mast flange foundation and the manufacturing method thereof, the foundation has the functional characteristics of a traditional step foundation, due to the fact that the concrete columns are provided with the cavities, the overall weight is greatly reduced, industrialized production, transportation and hoisting are achieved, the working efficiency is improved, and the construction quality is guaranteed.

本发明属于电力和通讯技术领域，尤其是涉及一种轻型预制塔桅法兰基础及其制作方法，轻型预制塔桅法兰基础包括砼柱和砼底盘，其特征在于砼柱外形为圆台或四棱台，砼柱主要由带有主筋和箍筋的混凝土形成，内部设有空腔，空腔顶部为封闭形式或顶部留有开孔与外界连通，砼柱顶部设有金属法兰，金属法兰主要由法兰盘、钢板圈、筋板构成，钢板圈包裹在砼柱顶部的外围且与法兰盘的内孔处焊接，主筋与金属法兰连接。本发明的轻型预制塔桅法兰基础及其制作方法，该基础具有传统台阶基础的功能特点，因砼柱设有空腔，使得整体重量大幅降低，工厂化生产，运输，吊装得以实现，既提高了工作效率，又保证了施工质量。
