Parabolic cylindrical surface thin-shell horizontal warehouse applying external prestress and construction method
The invention relates to the technical field of granary construction, in particular to a parabolic cylindrical surface thin-shell horizontal warehouse applying external prestress and a construction method. The structure mainly comprises a wallboard unit, a column unit, an external prestressed tendon unit, a roof panel unit and a roof panel rib unit, the wall columns are integrally cast in situ, the horizontal warehouse wall columns are integrally stressed, and the reinforcement requirement and the section size of the column unit can be reduced by matching with part of wing walls of the column unit; partial external load is balanced through external prestress, so that the internal force of the horizontal warehouse column, the wall and the foundation is reduced, and the sectional dimensions of the horizontal warehouse column, the wall and the foundation are further reduced; the parabolic cylindrical surface thin shell is adopted for the roof, and the roof panel and the ribs are in an axial compression state or a small eccentric compression state, so that the compression resistance of concrete can be brought into full play, a smaller and thinner roof panel section and fewer reinforcing bars can be adopted, and the material cost is saved; the external pre-stressed tendons are high-strength pre-stressed steel strands, so that the tensile capacity of the external pre-stressed tendons can be fully exerted, and the safety reserve is high.
本发明涉及粮仓施工技术领域，具体涉及一种施加体外预应力的抛物线柱面薄壳平房仓及施工方法。主要包括墙板单元，柱单元，体外预应力筋单元，屋面板单元，屋面板肋单元；采用墙柱整体现浇，平房仓墙柱整体受力，配合柱单元的部分翼墙，能够降低柱单元的配筋需求和截面尺寸；通过体外预应力平衡部分外荷载，从而降低平房仓柱、墙、基础的内力，进一步减小平房仓柱、墙、基础的截面尺寸；屋面采用抛物线型柱面薄壳，屋面板、肋处于轴心受压或小偏心受压状态，能够充分发挥混凝土抗压性能，进而可采用较小较薄的屋面板截面及较少的配筋，节省材料成本；体外预应力筋采用高强预应力钢绞线，可充分发挥其抗拉能力，且安全储备高。
