Composite beam prefabricated floor assembly and composite beam

Abstract

The invention discloses a composite beam prefabricated floor assembly and a composite beam, relates to the field of building structures, and solves the problems of cumbersome construction, prolonging the construction period and high cost of the existing composite beam. The adopted technical scheme is: prefabricated composite beam Base plate assembly, including prefabricated base plate and support parts, embedded connectors in the prefabricated base plate, support parts detachably connected to the lower side or inner side of the prefabricated base plate; internal reinforcement of the prefabricated base plate, the reinforcement includes stirrups and longitudinal bars, and the stirrups include The embedded part buried in the prefabricated base plate and the exposed part exposed on the upper side or outside of the prefabricated base plate. The prefabricated bottom slab is a prefabricated arched bottom slab or a prefabricated flat beam, and the outer side or upper surface of the prefabricated bottom slab is poured with a composite layer of concrete and connected in shear, which is a composite beam. The invention not only avoids formwork construction, but also avoids support, reduces engineering quantity, shortens construction period and saves cost. The prefabricated base plate can be made thinner, and its bending resistance during the construction stage can be adjusted to reduce types and promote the development of prefabricated buildings.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a composite beam of an assembled building. Background technique [0002] According to the shape of the axis, beams can be divided into straight beams and curved beams, and curved beams are mainly arched beams. The existing arch beams are generally cast directly on site, requiring formwork, the process is cumbersome, and the construction period is increased. [0003] Composite beams include prefabricated beams and cast-in-place sections. During the construction of the existing laminated straight beams, the two ends of the prefabricated beams are first supported on two columns, and then the cast-in-situ part is directly poured on the upper part of the prefabricated beams. When the span of the prefabricated beam is large, depending on the support of the prefabricated composite beam alone, it is easy to cause damage to the prefabricated beam during pouring and affect th...
