Abstract

The invention discloses a large cantilever steel truss concrete floor structure and a construction method, and relates to the technical field of building engineering. The problem of floor cracking issolved, and the integrity of a building structure is not affected. The large cantilever steel truss concrete floor structure comprises a steel truss. The first end of the steel truss is fixed to a building body structure, and the second end of the steel truss is suspended. An upper concrete layer and a lower concrete layer are separately arranged on the upper chord top surface and the lower chordtop surface of the steel truss in a pouring mode, the upper concrete layer comprises a pre-pouring concrete area and a post-pouring concrete belt, wherein the pre-pouring concrete area and a post-pouring concrete belt are connected together, the post-pouring concrete belt is arranged near the first end of the steel truss, and the extending direction of the post-pouring concrete belt is perpendicular to the extending direction of the steel truss. The large cantilever steel truss concrete floor structure and the construction method can be used for building construction.

Description

Technical field [0001] The invention relates to the technical field of construction engineering, in particular to a large cantilever steel truss concrete floor structure and a construction method. Background technique [0002] Cantilevered structure is one of the common structural forms in engineering structure, such as canopy, canopy, external balcony, cantilever, etc. in construction engineering. This kind of structure is a cantilevered structure by cantilevering beams or slabs from the main structure. It is essentially a beam-slab structure. Steel trusses refer to trusses made of steel, such as roof structure crane beams, bridges and hydraulic gates of industrial and civil buildings. Steel trusses are commonly used as the main load-bearing components. In the construction process of large cantilever steel trusses, temporary supports are often used to ensure construction operations such as component installation and concrete floor pouring, and the temporary supports are removed...
