Fabricated integral type hollow floor and prefabricated high-rib laminated bottom plate thereof

Abstract

The invention discloses a fabricated integral type hollow floor and a prefabricated high-rib laminated bottom plate thereof. The fabricated integral type hollow floor comprises a fabricated integral type hollow plate and laminated frame beams. The fabricated integral type hollow plate comprises the prefabricated high-rib laminated bottom plate, hollow plate built-in filling bodies, cast-in-place laminated layers and cast-in-place laminated ribs. The prefabricated high-rib laminated bottom plate is provided with upturning ribs, shear keys are arranged on the side face of the prefabricated high-rib laminated bottom plate and the upper surfaces of the upturning ribs, truss steel bars or shear short bars are arranged on the upper surfaces of the upturning ribs and connected with the cast-in-place laminated layers or the cast-in-place laminated ribs, and the upper surfaces of the upturning ribs are rough surfaces. The hollow plate built-in filling bodies are light filling blocks or thin-wall components or fast-easy net disassembly-free formworks. The laminated frame beams are arranged on the periphery of the fabricated integral hollow plate. The hollow floor structure is light in self-weight, large in plate span, large in plate rigidity and high in bearing capacity, the use number of steel bars is reduced, the structure height is remarkably reduced, the use clearance is improved, alarge number of formworks are saved, and the construction period is effectively shortened.

Description

technical field

[0001] The invention relates to the technical field of construction engineering, in particular to an assembled integral hollow floor and a prefabricated high-rib laminated floor. Background technique

[0002] With the state's control of mining resources, environmental protection requirements, and rising labor costs, the state requires more environmental protection and energy conservation in the construction industry, and also introduces various energy-saving and environmental protection new construction technologies, such as prefabricated buildings and cast-in-place concrete hollow buildings cover etc. The prefabricated components of the prefabricated building are standardized production in the factory to ensure quality. Among them, the prefabricated laminated floor slab reduces the construction process of erecting frames and formwork installation, reduces manpower requirements, reduces costs such as labor and formwork materials, and speeds up construction. ...
