Abstract

The invention provides a prefabricated reinforced concrete column and composition board joint and a construction process. The joint comprises a reinforced concrete column body, a steel plate sandwichconcrete composition board and a connecting assembly, wherein the connecting assembly is connected to the reinforced concrete column body and the steel plate sandwich concrete composition board, a first connecting hole is formed in the steel plate sandwich concrete composition board, the reinforced concrete column body penetrates through the first connecting hole and is connected to the steel plate sandwich concrete composition board through the connecting assembly, a traditional concept of a cast-in-place plate column structure and a fabricated structure are broken through, and compared witha common cast-in-place plate column structure, not only are the advantages of the fabricated combined structure achieved, but also the stress performance of the plate-column structure joint is guaranteed.

Description

technical field [0001] The invention belongs to the field of building structures, and in particular relates to a joint of a prefabricated reinforced concrete column and a composite plate and a construction process. Background technique [0002] The column-slab structure is a structure with slabs and columns as the load-bearing system. It is characterized by no need for beams under the slab, good integrity, more flexible space layout, and can effectively increase the storey height. It is widely used in various buildings such as residences, factories, warehouses, etc., and has good economic benefits. The cast-in-place method of building column-slab structures is a relatively mature technology. The integrity of the cast-in-place structure is strong, but there are a lot of templates required in the construction process, long maintenance time, waste of a lot of materials, pollution of the environment and uneven project quality. Qi and other issues. Prefabricated buildings can e...
