Fabricated invisible-beam floor plate

Abstract

The invention provides a fabricated invisible-beam floor plate, and belongs to the field of components of buildings. The invisible-beam floor plate is an integral module formed by beams whose web plates are provided with holes and a reinforced concrete floor plate, wherein the beams which are well prefabricated in a factory are firstly used as borders of the integral module of a beam plate; precast concrete is poured at the bottoms of the beams; afterwards, pipelines can be freely laid on precast concrete layers; the pipelines among different plate blocks pass through the holes of the web plates of the beams; lightweight concrete is poured after the laying is completed. According to the invisible-beam floor plate, through the integration of the beam plate, on the premise that the bearing capacity is not decreased, the integral thickness of the beam plate is decreased; the clear space of a building is improved; the space is arranged more flexibly; upper and lower flanges of the beams are all embedded in the concrete of the floor plate; on one hand, the local stableness of a component can be improved by the concrete reserved around the beams, and on the other hand, the fireproof andanticorrosive problems of a steel structural beam are relieved to a certain extent; the personalized layouts of the pipelines are facilitated by the ways that the web plates are provided with the holes and the floor plates are hierarchically poured, and the later maintenance and modification are convenient.

Description

technical field [0001] The invention designs an assembled invisible beam floor, which belongs to the field of building components. Background technique [0002] my country's annual urban and rural new housing area is 2 billion cubic meters, of which more than 80% are high-energy buildings, and the energy consumption per unit building area in my country is more than twice that of developed countries. According to the statistics of the China Iron and Steel Association, China's steel output exceeded 700 million tons in 2011, ranking first in the world's steel output for 16 consecutive years. Correspondingly, the current domestic construction industrialization level is less than 10%, while the steel structure building area in developed countries accounts for The total construction area is more than 50%, and Japan accounts for 80%. As the country with the largest construction scale and steel output in the world, China lags behind seriously in the development of housing steel str...
