Precast pile and bearing platform fabricated type foundation tenon type flange connecting structure and construction method

Abstract

The invention relates to a precast pile and bearing platform fabricated type foundation tenon type flange connecting structure and a construction method. The precast pile and bearing platform fabricated type foundation tenon type flange connecting structure comprises a tube pile and a bearing platform. Supporting steel tubes are arranged between the tube pile and the bearing platform, a lower flange disc attached to the end face of the tube pile is arranged at the lower ends of the supporting steel tubes in a sleeving mode, an upper flange disc attached to the end face of the bearing platformis arranged at the upper ends of the supporting steel tubes in a sleeving mode, upper deformed steel bars are arranged on the upper flange disc, one end of each upper deformed steel bar is inserted into the bearing platform, an upper fastening nut is arranged at the other end of each upper deformed steel bar, and the upper fastening nuts are used for locking the upper flange disc to the lower endface of the bearing platform. An upper fastening mechanism is arranged on the lower flange disc in a penetrating mode, one end of the upper fastening mechanism is inserted into the tube pile, a lowerfastening mechanism is arranged at the other ends of lower deformed steel bars, and the lower fastening mechanism is used for locking the lower flange disc to the end face of the tube pile. The precast pile and bearing platform fabricated type foundation tenon type flange connecting structure is reasonable in structure and easy and convenient to operate, field welding is not needed when the tube pile and the bearing platform are connected, manual cost is greatly reduced, field operation is reduced, fire disaster risks of a construction site are reduced, the construction speed is improved, andmeanwhile the structure is stable, reliable and high in safety.

Description

technical field [0001] The invention relates to a tenon-type flange connection structure and a construction method of a prefabricated pile-cap assembly type foundation. Background technique [0002] At present, vigorously developing prefabricated buildings has become the development trend of the modernization of my country's construction industry. Prefabricated buildings refer to buildings that are prefabricated in factories and delivered to the construction site for assembly. The promotion of prefabricated buildings can not only improve the quality and quality of construction projects, but also significantly reduce building energy consumption. The characteristics of the steel structure determine that it is very suitable for use in prefabricated buildings. [0003] In structures with large spans or heavy loads such as industrial buildings or public buildings, the advantages of mechanical properties of steel structures make them have unique application advantages. In the p...

Problems solved by technology

In the past, the connection construction of pipe piles and caps usually adopts the method of on-site processing and on-site installation, which requires on-site construction welding, resulting in a large amount of on-site construction work and occupying the site space
