Description

Composite support system for soft foundation overrun high-large template Technical Field The utility model belongs to the field of buildings, and particularly relates to a soft foundation overrun high-large template composite support system. Background Along with the development of society and the continuous improvement of the technological level, the industrial field of China also rapidly develops, and the multifunctional building is also continuously growing. In order to meet various functional requirements, concrete structures of oversized space frames and ultra-thick floors are often found in building designs. When encountering ultra-high and ultra-thick floors in construction, careful handling is often needed, and foundation backfilling is performed before construction of a main body structure roof according to a frame structure construction procedure, so that a floor formwork support system is located on backfilling soil, the roof deflection deformation is inevitably increased along with load increase and span increase, construction quality is difficult to guarantee, and meanwhile, the safety production coefficient is reduced, so that the overall stability of the formwork support system is important. Disclosure of utility model The utility model aims to solve the technical problems of overcoming the defects of the prior art and providing an overrun high and large template composite supporting system which can effectively prevent the overrun of deflection deformation of a top plate caused by the subsidence of a soft soil layer supporting foundation and the deformation of a single frame body. The technical scheme includes that the soft foundation overrun high-high template composite supporting system comprises a lime soil backfill layer, steel plates, fixed keels, a top plate template and a plurality of vertically overlapped bracket bodies arranged between the steel plates and the fixed keels, wherein composite connectors are arranged between adjacent bracket bodies to be connected, each bracket body is provided with a consolidating structure, the steel plates are arranged on the upper side of the soft foundation, the lower sides of the bracket bodies are fixed on the steel plates through channel steel, the top plate template is arranged on the upper sides of the fixed keels, and the upper sides of the bracket bodies are connected with the fixed keels through adjustable supports.
