Fabricated cast-in-place combined beam structure

Abstract

The invention discloses a fabricated cast-in-place combined beam structure. The fabricated cast-in-place combined beam structure comprises a cast-in-place core beam and prefabricated side beam plateslocated on the two sides of the cast-in-place core beam; each prefabricated side beam plate comprises a prefabricated plate and bonding surface constructional steel bars, and the bonding surface constructional steel bars are connected to the surface of one side of the corresponding prefabricated plates in an embedded manner; the cast-in-place core beam comprises a cast-in-place beam body, upper opening hoops, lower opening hoops, core beam bottom ribs and core beam surface ribs; the upper opening hoops are located on the top of the cast-in-place beam body, the lower opening hoops are located at the bottom of the cast-in-place beam body, and openings of the upper opening hoops and openings of the lower opening hoops are oppositely arranged and connected to form annular hoops; and the core beam bottom ribs are located at the inner bottoms of the annular hoops, and the core beam surface ribs are located on the inner tops of the annular hoops. According to the fabricated cast-in-place combined beam structure, the bonding surfaces between the prefabricated side beam plates and the cast-in-place core beam are enhanced, and therefore the prefabricated beam and the cast-in-place core beamin the combined beam can better jointly work to enhance the bonding surfaces.

Description

technical field [0001] The invention relates to the technical field of construction engineering, and more specifically relates to an assembled cast-in-place composite beam structure. Background technique [0002] In recent years, my country has actively explored the development of prefabricated buildings. In this field, there is a prefabricated cast-in-place composite beam-slab structure. The composite beam of this structure is composed of side prefabricated beams and middle cast-in-place core beams. The joint surface between the prefabricated beam and the cast-in-place core beam in the beam is a weak surface, which is easily damaged and cannot make the prefabricated beam and the core beam work together, thus affecting the quality of the project. Contents of the invention [0003] In view of this, the present invention provides an assembled cast-in-place composite beam structure, aiming to solve at least one of the technical problems in the prior art. [0004] In order to ...
