The invention discloses a GRC template system of a spherical shell structure. The GRC template system comprises outer-side GRC template units, a concrete spherical shell structure, inner-side GRC template units, a conversion structure unit and a support frame body, wherein the conversion structure unit is installed on the support frame body, the inner-side GRC template units are connected with the conversion structure unit by use of bolts, and the outer surfaces of the inner-side GRC template units are successively provided with the concrete spherical shell structure and the outer-side GRC template units. The GRC template system and the construction method have the following advantages: 1, the weights of GRC templates are light, factory prefabrication can be realized, the onsite splicing amount is reduced, and the construction efficiency and the construction quality are improved; 2, main components of the GRC templates are glass fibers and cement, the materials are easily available, less timber and steel are used, energy is saved, and environment is protected; 4, inner-side GRC templates can be used as permanent structures, the template dismounting workload is reduced, and the construction efficiency is improved; and 5, the system and the method can be widely applied to construction of a spherical shell concrete structure.
Description
technical field [0001] The invention relates to the field of GRC formwork systems and construction methods, in particular to a GRC formwork system with a spherical shell structure and a construction method thereof. Background technique [0002] The concrete spherical shell structure is widely used because of its beautiful appearance and good waterproof effect. Currently, there are three commonly used formwork systems for concrete spherical shell structures: wood formwork, steel formwork and plastic formwork. Wooden formwork needs to be assembled in large quantities on site, and there are problems such as poor joints and poor concrete construction quality; although steel formwork can be finalized and processed in batches in the factory, it is heavy, expensive, and low in installation efficiency, and at the same time increases the difficulty of supporting system design; Moreover, the fire resistance of the above three formworks is poor, and the formwork needs to be dismantled ...
