A cast-in-situ concrete invisible beam floor with separated pipelines and its construction method

Abstract

The invention discloses a cast-in-situ concrete hidden beam floor with separated pipelines and a construction method of the floor. The cast-in-situ concrete hidden beam floor includes a cement fiberboard, a concrete floor slab and concrete columns; a bottom mold is mounted between the lower surfaces of the lower flanges of steel beams on the two sides of the floor slab, and side molds are mountedon the upper surface of the bottom mold; after elastic wires are positioned, triangular steel bar trusses are bound, lamp wires for users on the lower floor to use are embedded in the triangular steelbar trusses, a top mold and a square supporting formwork are mounted, and concrete is poured from an upper opening of the square supporting formwork; the bottom mold, the side molds, the top mold andthe square supporting formwork are removed after the concrete reaches designed strength; water pipelines and electricity pipelines are laid on the upper surface of the concrete floor slab for users on the upper floor to use. The upper flanges of the steel beams and the upper surfaces of the concrete columns are provided with the cement fiberboard to achieve sealing, and a cavity is formed betweenthe cement fiberboard and the concrete floor slab. The floor can achieve separation of a building structure and the pipelines, the steel beams are hidden inside the floor slab, and flexible arrangement of walls is achieved.

Description

technical field [0001] The invention relates to the technical field of building structural components, in particular to a cast-in-situ concrete invisible beam floor slab with separated pipelines and a construction method. Background technique [0002] The cast-in-place concrete floor slab is constructed through a series of processes on site according to the design position, supporting formwork, positioning spring lines, binding steel bars, pouring on site, maintaining and removing formwork, etc. It has good integrity, firm connection, and good seismic performance, but the construction process is cumbersome. Time-consuming and labor-intensive, causing great environmental pollution. [0003] Common forms of cast-in-place concrete slabs include slab slabs, ribbed slabs, and beamless slabs. Different slab forms are suitable for different spans. There are also various forms of reinforcement in the floor slab, including: double-layer two-way reinforcement, triangular steel truss...
