Problems solved by technology

One of the advantages of this structural system is that the steel structure frame can be tightly connected into a whole through the cast-in-place concrete structure floor, and at the same time, it can meet the functions of sound insulation and heat preservation of floors; It requires a lot of labor, and a certain amount of formwork and supports are needed, and the on-site concrete construction brings a lot of dust, which has a certain impact on the urban environment

Abstract

An assembled type steel framework prefabricated concrete floor slab structure comprises a steel framework and a prefabricated concrete floor slab. The steel framework comprises a steel column and a steel beam. The prefabricated concrete floor slab is located above the steel beam and installed on the steel beam through a connecting piece. The prefabricated concrete floor slab is a prestress hollow floor slab. The assembled type steel framework prefabricated concrete floor slab structure low in manufacturing cost and easy to popularize is provided.

Description

technical field [0001] The invention belongs to the technical field of assembled buildings, in particular to an assembled steel frame prefabricated concrete floor structure. Background technique [0002] Industrialized buildings are gradually replacing large-scale on-site production buildings at home and abroad, using factory prefabrication and assembling in construction workshops. This is the direction of the development of the construction industry and has become a national strategy for the development of my country's construction industry to be vigorously implemented. At present, the main form of industrial buildings is prefabricated concrete structures. In view of the large inventory of steel production in my country and the advantages of environmental protection and high efficiency of steel structures in urban construction, vigorously promoting steel structure buildings is also a development direction. [0003] Existing steel structure buildings are mainly made of steel...
