PROCESS OF ERECTION OF BUILDING STRUCTURE Russian patent published in 1997 - IPC

FIELD: construction industry, building of civil, industrial, agricultural buildings and structures and transport ways. SUBSTANCE: building structure is formed by layer by layer laying by method of concrete spraying. In this case air-placed mass is prepared right at erection site using local ground that is excavated , ground and dried. Air-placed mass is modified by control of oxidation-reconstruction number of atmosphere of cone, for instance, by supply of oxygen. Composition of air-placed mass can be modified in individual zones of cone with the aid of selective feed of oxygen into these zones of cone. Formation of pores inside layers is executed by addition of pore-forming agent, for example, by feed of particles of fuel or gas former ( saw dust, limestone, etc ) into central zone of cone. Air-placed mass can also be placed into mobile moulding plate. Composition of air-placed mass can be corrected by addition of components missing in local ground either in advance or immediately into cone of air-placing plant or by deposition on area of laying of air-placed mass, for instance, by feed to moulding plate. EFFECT: high productivity of process with minimal waste, possibility of varying density and other properties of laid material over section of layer, refusal to use bonding materials and forms, decreased expenses for transportation and transfer of materials. 7 cl, 3 dwg
