Description

预应力预制钢筋混凝土屋面板
技术领域:
本实用新型涉及一种工业厂房钢筋混凝土屋面板。
技术背景:
传统工业厂房的屋面系统由预制钢筋混凝土折线型屋架、预制钢筋混凝土大型屋面板和支撑系统组成,构件种类繁多,现场拼装施工量大,加上屋面板接头较多,防水要求较高,投资相应增大。
发明内容:
本实用新型的目的在于:提供一种结构合理、重量轻、可工厂化生产、成本低、式样美观的预应力预制钢筋混凝土屋面板,以解决现有技术存在的问题。
本实用新型是这样构成的:它包括混凝土板(1),预应力筋(2),混凝土板(1)为“Z”形,预应力筋(2)埋在混凝土板(1)的一边内。
本实用新型与现有技术相比,具有以下优点:
1、截面折算刚度大、结构受力有明显优势、材料省。
2、采用预应力技术,根据其用途,在适当部位施加预应力,使之能符合结构构件的受力特点,构件断面大幅度减小,自重大幅度减轻,节省大量投资,经济效益显著。
3、采用标准单元预制,工厂化集中批量加工,现场拼装灵活,造价低、效率高,可以缩短施工工期50%,避免了砌筑、支模、现浇等大量的现场工作,而且气候对施工的影响较小。
4、屋面系统板、梁、支撑合一,刚度大,减少了屋架、屋面板、及屋面支撑系统等多种构件的制作、安装的繁杂过程;因“Z”型板整体预制,本身具有自防水功能,屋面接头少,为此、防水施工便捷且投资低。
5、利用构件本身的造型和空间变化,美化了建筑物。
附图说明:
附图1为本实用新型的结构示意图;
附图2为本实用新型的使用状态图。
具体实施方式:
本实用新型的实施例:用混凝土浇注成“Z”形混凝土板(1),预应力筋(2)埋在混凝土板(1)的一边内。
