Prefabricated assembling type steel-reinforced concrete column-steel beam frame structure system and construction method

Abstract

The invention discloses a prefabricated assembling type steel-reinforced concrete column-steel beam frame structure system and a construction method. The prefabricated assembling type steel-reinforced concrete column-steel beam frame structure system comprises an upper prefabricated steel-reinforced concrete column, a prefabricated steel-reinforced concrete joint column and a lower prefabricated steel-reinforced concrete column. In the construction method, the upper prefabricated steel-reinforced concrete column, the prefabricated steel-reinforced concrete joint column and the lower prefabricated steel-reinforced concrete column are manufactured in a factory; in the construction field, the upper prefabricated steel-reinforced concrete column and the prefabricated steel-reinforced concrete joint column are spliced, the prefabricated steel-reinforced concrete joint column and the lower prefabricated steel-reinforced concrete column are spliced, and concrete pouring is carried out on spliced positions. The prefabricated assembling type steel-reinforced concrete column-steel beam frame structure system and the construction method have the advantages that in the field construction, it is only needed to fixedly connect the lower end of an upper center type steel column and the upper end of a joint center type steel column and fixedly connect the lower end of the joint center type steel column and the upper end of a lower center type steel column, and then an upper concrete to-be-poured layer and a lower concrete to-be-poured layer are poured; the field construction is simple, the construction period is short, the field wet operation is little, and transporting is convenient.

Description

technical field [0001] The invention relates to a concrete structure system, in particular to a prefabricated assembled steel concrete column-steel beam frame structure system and a construction method. Background technique [0002] Compared with cast-in-place concrete structures, prefabricated concrete structures have many advantages, such as being convenient for large-scale industrial production, easy to control the construction quality, less wet work in on-site construction, fast construction speed, high economic benefits, and less environmental pollution. In recent years, national and local governments have attached great importance to the industrialization of construction. Therefore, the development of prefabricated structures and the realization of industrialization of construction are one of the main trends in the development of the construction industry in the future. In our country, the frame structure is the most widespread form of building structure, and it is als...

AI Technical Summary

Problems solved by technology

The following problems exist in the use of cast-in-place joints: (1) Due to the complex layout and large number of central steel columns, longitudinal bars, and stirrups in the core area of ​​the joints, it is extremely inconvenient to connect on-site, resulting in many on-site connection procedures, complicated construction and greatly extended Construction period; (2) Due to the need for on-site pouring of concrete in the joint area of ​​steel concrete columns and steel beams, there are many wet operations on site.

Of course, there are also prefabricated steel concrete columns and steel beam connectors produced in factories, but the prefabricated components of this structure are bulky and difficult to transport
