The invention relates to the field of grain storage bin construction, in particular to a tension arch rigid frame bin and a construction method thereof to solve the technical problems that an existing bent frame bin leaks air, and a rigid frame folding beam bin is small in rigidity, large in deformation, high in cost and the like, the tension arch rigid frame bin comprises a tension cable rigid frame unit, and the tension cable rigid frame unit comprises an arc arch, a rigid column and a steel strand; the two rigid columns are located on the two sides of the arc-shaped arch and connected with the end points of the arc-shaped arch, the connecting joints can transmit bending moment, and the two rigid columns and the arc-shaped arch are integrally connected to form a rigid frame arch; the steel strand is positioned in the rigid frame arch and two ends of the steel strand are respectively connected with the rigid frame arch; and the steel strand is loaded with prestress. The tension arch rigid frame bin is large in rigidity, small in deformation, high in external load resistance, low in foundation cost, high in prestress reliability and easy to construct.
本发明涉及粮食储备仓建设领域，尤其是涉及一种张拉拱刚架仓及其施工方法，以缓解现有的排架仓存在漏气问题、刚架折梁仓的刚度小，变形大，成本高等技术问题，包括张拉索刚架单元，张拉索刚架单元包括弧形拱、刚柱和钢绞线；两个刚柱位于弧形拱的两侧并与弧形拱的端点相连，相连节点能够传递弯矩，两个刚柱与弧形拱一体连接形成刚架拱；钢绞线位于刚架拱内部且两端分别与刚架拱相连；钢绞线加载有预应力。本方案提供的张拉拱刚架仓刚度大，变形小，抵抗外荷载能力强、基础费用低、预应力可靠性高、施工简单。
