Abstract

The invention discloses a steel beam-concrete composite floor slab combined assembly system. The steel beam-concrete composite floor slab combined assembly system comprises truss floors, a secondary beam and a primary beam, wherein the multiple truss floors are built onto a main framework formed by the primary beam; a first fixed connector which is connected to the truss floors is arranged on theprimary beam; the secondary beam is fixedly arranged below the truss floors; a second fixed connector which is connected to the truss floors is arranged on the secondary beam; the two ends of the secondary beam are provided with connecting plates; and the secondary beam is connected to the primary beam through the connecting plates. According to the steel beam-concrete composite floor slab combined assembly system disclosed by the invention, the truss floors, the secondary beam and the primary beam are prefabricated together at a plant, so that the initial deflection problem, caused by wet concrete if the concrete is poured on a site, of floors and the beams is avoided, and therefore, the purpose of increasing floor strength and rigidity is achieved; and meanwhile, the assembly system alsocan greatly shorten the construction period, and improves construction efficiency.

Description

technical field

[0001] The invention belongs to the technical field of assembled prefabricated floor slab structures, in particular to a steel beam-concrete composite floor slab assembly system. Background technique

[0002] The traditional building construction method is the pouring-in-site construction mode, that is, the operation mode from erecting scaffolding, setting up formwork, binding steel bars to pouring concrete on site. On-site pouring construction produces a lot of dust, noise, sewage, etc. during the construction process, and the construction speed is slow, the construction intensity is high, and it is greatly affected by seasonal climate. Therefore, in recent years, my country has been continuously promoting the application of prefabricated buildings. The prefabricated building is based on the prefabricated production of component factories and on-site assembly installation. It is characterized by standardized design, factory production, assembly construction...
