1．钢筋混凝土拱板屋盖由单一的板架合一的拱扳屋架结构构件组成整个屋盖承重结构，打破了惯用的屋架与屋面板等组成屋盖承重结构的老框框。钢骨架轻型板
1. Reinforced concrete arch slab roof by single plate and frame combination of arch pull roof truss structure composed of the whole roof bearing structure, breaking the conventional roof and roof panel roof load-bearing structure of the old frame.
2．钢筋混凝土拱板屋盖是具有多功能的屋盖结构体系，改进了旧屋盖盖体系屋盖结构构造的复杂性。妥善地处理了屋盖结构的承重、保温(隔热)、防水和顶棚等多种技术要求，比较合理地解决了屋盖体系层次繁琐的现象。
2. Reinforced concrete arch slab roof is a roof structure system of the multi function and the complexity of the old house covered with lid system roof structure is improved. Properly deal with the requirements of roof structure of bearing, insulation (insulation), waterproof and ceiling and so on many kinds of technology, reasonable solution to the roof system level complicated phenomenon.
3.拱板屋盖是空间结构，整体性奸，屋盖重量轻，支承长度大，抗震性能较好。
3 the roof of the arch is a space structure, the integrity of the rape, the roof of the light weight, the length of the supporting length, seismic performance is better.
4．拱板屋盖结构形式合理，结构性能好，上弦拱形板主要承受压力， 有利于充分发挥混凝土材料受压强度高的特性，板面不易裂缝，防水容易解决。保温或隔热层处理方便。室内顶棚平整，美观大方。
4. Arch slab roof structure reasonable, good performance of structure, winding arched plate mainly under pressure, is conducive to give full play to the characteristics of high strength concrete materials under compression, surface is not easy to crack, waterproof easy to solve. Heat preservation or heat insulation layer processing convenient. The indoor ceiling is smooth, beautiful and generous.
5．在拱板屋架及屋面板预制中布需要复杂的施工设备，一般工地均能生产。屋盖施工工序少，把拱板屋架安装就位后，屋面工程就基本完成，高空作业工作量少。
5 in the arch roof truss and roof panel in prefabricated construction equipment need cloth complex, the general site can be produced. The roof construction process less, the installation of arch roof truss, roofing project basically completed, aerial work less.
6．技术经济指标好。与常用的同跨度屋盖结构相比，拱板屋盖减少了钢材、水泥等用量，降低了屋盖造价三分之一左右。
6 good technical and economic indicators. Compared with the common roof structures, the roof of the arch is reduced by the amount of steel, cement, etc., and the cost of the roof is about 1/3..
