Reinforced concrete ribbed grid-like large floorslab and preparation method thereof

Abstract

The invention relates to a steel bar concrete dense-rib well-shape building roof cover and relative construction method. It directly uses molded assemble phosphor plasterboard as the undetachable mold plate of on-site irrigation steel bar concrete dense-rib well-shape building roof cover, and uses the bottom plate of assemble phosphor plasterboard as the plaster suspending roof. Compared to present technique, it has lower height, light weight, undetachable phosphor plaster mold plate, easy construction, and sound, heat and fire insulation with lower cost.

Description

Technical field: [0001] The invention relates to a building floor and a manufacturing method thereof, in particular to a reinforced concrete fine-ribbed well-shaped slab floor suitable for high-rise buildings with large bays and large column nets and a manufacturing method thereof. Background technique: [0002] At present, compared with the traditional solid reinforced concrete slab floor, the widely used reinforced concrete slab floor with dense ribs has better structural integrity and spatial rigidity, and has the characteristics of three-dimensional force in space, and its structural self-weight It is light, only 40% to 50% of the self-weight of a general solid reinforced concrete slab, saving concrete and steel consumption significantly, and it adapts to the requirements of the Ministry of Construction for "flexible division of rooms with large bays and large column networks" and overcomes the "inconvenient There are beams in the wall, which increases the net height of ...

Problems solved by technology

[0002] At present, compared with the traditional solid reinforced concrete slab floor, the widely used reinforced concrete slab floor with dense ribs has better structural integrity and spatial rigidity, and has the characteristics of three-dimensional force in space, and its structural self-weight It is light, only 40% to 50% of the self-weight of a general solid reinforced concrete slab, saving concrete and steel consumption significantly, and it adapts to the requirements of the Ministry of Construction for "flexible division of rooms with large bays and large column networks" and overcomes the "inconvenient There are beams in the wall, which increases the net height of the floor; but the densely ribbed tic-tac-toe large slab floor in the prior art requires a large number of wooden formwork, steel formwork or plastic shell formwork, the formwork turnover cost is high, and the concrete curing After completion, the formwork needs to be disassembled for turnover, which consumes man-hours and prolongs the construction period

In addition, due to the thin board (50mm ~ 60mm), the sound insulation and thermal insulation effect is poor. In residential and office buildings, it is often necessary to separate the ceiling (metal mesh ceiling, gypsum board ceiling, etc.) during decoration, which increases the working hours and costs.
