In order to obtain a proved solution for composing a new type molding system, a model of main framework of a dome mold was made as compared with natural sizes on a scale 1/10. As a result of analyzing the values of its constructional and technical-economical parameters there has been found a completely new solution for constructing a molding system with thin-shielded molds. Construction of a monolithic dome technologically is quite a complex and time-consuming process that in the first place is explained by the fact that an appropriate mold is necessary to create before. It describes a completely innovative construction of a molding system of the dome of 12 m in diameter with thin-shielded molds in levels and with an original solution of connection and fixation of the curved edges of the cathedral the second in size in Georgia on Mount Makhata in Tbilisi being under construction. It has been established that it is very effective for the selection of a mold system of a large-diameter monolithic iron-concrete dome to carefully study and examine its minimized model. It has been found out that by thin-shielded molds it is possible to compose separate load-bearing elements of various complexity and configuration included in the molding system. Also, the process of joining in thickened blocks of the above-mentioned elements as well as their mounting and firm fixation has been simplified. It should be noted as well unlimited possibilities of increasing extremely the features of their toughness by adding the edges of simple hardness. And what is more important, use of standard materials and molding devices significantly reduces labor and material consumption connected with formation of molds.
