Hollow double-steel-pipe high-pressure gas pre-tensioning concrete column and construction method thereof
The invention provides a hollow double-steel-pipe high-pressure gas pre-tensioning concrete column and a construction method thereof. The pre-tensioning concrete column comprises an outer steel pipe, a cover plate I, an inner steel pipe, an inflation pipe, a cover plate II and interlayer concrete. The outer steel pipe is a hollow circular pipe with two open ends. And an inflation pipe through hole is formed in the pipe wall of the outer steel pipe. An air cavity is defined by the cover plate I and the inner steel pipe. And the gas cavity is filled with high-pressure gas. An annular pouring space is defined by the outer steel pipe, the cover plate I, the inner steel pipe and the cover plate II. Interlayer concrete is arranged in the annular pouring space. High-pressure gas prevents local buckling of the steel pipe, and the overall vertical bearing capacity of the structural component is improved. The compression bearing capacity of the structural member is improved through high-pressure gas, and the weight of building materials needed under the same stress condition can be effectively reduced. The prefabrication process is time-saving and labor-saving, and the production operation efficiency is
发明提供一种中空双钢管高压气体预拉混凝土柱及其施工方法。该预拉混凝土柱包括外钢管、盖板Ⅰ、内钢管、充气管、盖板Ⅱ和夹层混凝土。所述外钢管为两端敞口的中空圆管。所述外钢管的管壁上设置有充气管通过孔。所述盖板Ⅰ和内钢管合围出气腔。所述气腔中充填有高压气体。所述外钢管、盖板Ⅰ、内钢管和盖板Ⅱ围设出环形浇筑空间。所述环形浇筑空间中具有夹层混凝土。高压气体防止钢管局部屈曲，提高结构构件整体的竖向承载能力。高压气体提高结构构件的抗压承载力，可有效地减轻同等受力条件下所需建筑材料的重量。预制过程省时省力，大幅度提升生产作业效率。
