现浇框架结构屋面板的承重构件布置原则

按施工方法不同,框架结构分为现浇、半现浇、全装配、装配整体式几种。其中现浇框架分为梁、往现掇,楼板和屋面板预制(半现浇),以及全现浇方案。钢骨架轻型板

According to different construction methods, the frame structure is divided into several kinds of cast-in-place, semi cast, whole assembly and assemble.. The cast-in-place framework consists of beam, is to drop, floor and roof panels (semi precast cast-in-place), and cast-in-place scheme.

现浇框架的优点是对施工无特殊要求,质量容易保证、节省钢材、造价低、尺寸大的异形构件。但费模板、劳动力消耗多,现场湿作业很多,工期长。

The advantages of the cast in place frame are no special requirements for construction, quality easy to guarantee, save steel, low cost, large size of special-shaped component. But the fee template, labor consumption, on-site wet job a lot of time, a long period of time.

现浇框架分为梁、往现掇,楼板和屋面板预制(半现浇),以及全现浇方案。装配式框架构件在工厂制造,便于实现工业化.标准化、机械化施工,施工进度快,工期短,节约大量本材,改善劳动条件,节省劳动力。是建筑业发展方向。但钢材和水泥用量比较大,在某些情况下造价还可能较高。

The cast-in-place frame is divided into beam, is to pick, floor and roof panels (semi precast cast-in-place), and cast-in-place scheme. Assembly type frame member in the factory manufacture, easy to realize industrialization. Standardization, mechanization construction, fast construction speed, short construction period, save a lot of the material, improving labor conditions, save labor. Is the construction industry development direction. But the amount of steel and cement is relatively large, in some cases the cost may be higher.

全装配式框架只有在具备施工.运输、吊装条件下才能使用。这是由于全装配式框架对施工设备与技术要求高,比较复杂,梁柱接头部位不易确保质量要求,所以在施工力量较弱地区,电信楼最好不采用全装配式框架。

The fully fabricated frame is only available under construction, transportation and hoisting conditions.. This is due to the assembly of the whole frame of construction equipment and technical requirements of high, more complex, beam column joint is not easy to ensure the quality requirements, so in construction of power is weak area, telecommunications building it is best not to use the assembly frame.
