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. 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 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. 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 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 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..
