Connecting joint of prefabricated steel reinforced concrete column and profiled steel sheet composite plate and construction method

Abstract

The invention relates to a connecting joint of a prefabricated steel reinforced concrete column and a profiled steel sheet composite plate and a construction method. The connecting joint comprises theprefabricated steel reinforced concrete column and the profiled steel sheet composite plate. A supporting plate and embedded bolts are further included when a matched connection mode of the supporting plate and the embedded bolts is adopted. An outwards-extending composite plate and flange plates are connected in a matched mode, and an outwards-extending composite plate and high-strength bolts are further included. The construction method comprises the steps that the prefabricated steel reinforced concrete column with the supporting plate or the outwards-extending composite plate and the profiled steel sheet composite plate are manufactured; the prefabricated steel reinforced concrete column is mounted; the profiled steel sheet composite plate is hoisted, and the prefabricated steel reinforced concrete column is enabled to penetrate through a preformed hole in the profiled steel sheet composite plate; when the prefabricated steel reinforced concrete column is provided with the supporting plate, the profiled steel sheet composite plate falls onto the supporting plate, the embedded bolts penetrate through reserved bolt holes in the profiled steel sheet composite plate, and nuts arescrewed up until assembly is completed; and when the prefabricated steel reinforced concrete column is provided with the outwards-extending composite plate, the outwards-extending composite plate enters the reserved holes, the reserved bolt holes between the flange plates are guaranteed to be aligned, and the nuts are screwed up until assembly is completed.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a connection node of a prefabricated steel concrete column and a composite plate of a profiled steel plate and a construction method. Background technique [0002] The column-slab structure is a house structure with a load-bearing system composed of columns and floors. It is a special case of a frame structure and is generally made of reinforced concrete. Because there is no beam under the indoor floor of the slab-column structure, it is convenient for the layout of electromechanical pipelines, and can reduce the height of the building. It has the advantages of smooth and concise space and flexible layout. The column-slab structure is suitable for multi-storey factory buildings, warehouses and halls of public buildings, as well as office buildings and residences. [0003] At present, the construction technology of the column-slab structure is mainly ...
