A prefabricated invisible beam laminated floor with separated pipelines installed from bottom to top

Abstract

The invention discloses a pipeline separated assembly type hidden beam composite floor slab capable of being installed from bottom to top. The composite floor slab comprises a composite floor slab prefabricated layer, concrete upright columns, screw rods with hooks, angle steel, a composite floor slab cast-in-place layer and cement-fiber boards, wherein the composite floor slab prefabricated layerand the concrete upright columns are prefabricated and formed by pouring concrete on a steel bar truss and embedded hooks. The embedded hooks of the composite floor slab prefabricated layer are hoisted on steel beams with the angle steel from bottom to top through the screw rods with the hooks, and the composite floor slab prefabricated layer is closely attached to the lower flanges of the steelbeams; after hoisting is in position, the upper concrete is poured to form the composite floor slab cast-in-place layer, and water and electricity pipelines are laid through line holes in steel beam webs; finally, the cement-fiber boards are installed on the upper flanges of the steel beams to achieve closing. By means of the composite floor slab, the aim of separating a building structure from the pipelines can be achieved, the beams are hidden in the floor slab, flexible arrangement of a wall body is achieved, anti-fire and anti-corrosion problems of the steel beams are solved to a certain extent, and cavities formed in the steel beams plays a role of thermal insulation and sound isolation.

Description

technical field [0001] The invention relates to the technical field of building structural components, in particular to a prefabricated invisible beam laminated floor slab installed from bottom to top and separated from pipelines, which is suitable for prefabricated buildings. Background technique [0002] Prefabricated buildings have the characteristics of rapid construction, reduced labor intensity, and reduced environmental pollution. Under the vigorous promotion of national policies, prefabricated buildings have become a trend of innovation and development. At present, the prefabricated technology for the main structure of prefabricated buildings is relatively mature, but the three-board system that matches the main structure is relatively backward. [0003] After the precast concrete laminated floor slab is fixed by the triangular steel truss processed in the factory, the concrete is poured to form a prefabricated thin slab, and the laminated layer concrete is poured af...
