The floor system and its construction method composed of grc hollow box composite slabs

Abstract

The invention relates to a floor system composed of GRC hollow box body composite boards and a construction method thereof. The floor system composed of the GRC hollow box body composite boards is formed by mutually connecting special-shaped composite columns, composite beams and composite boards, wherein the special-shaped composite columns are special-shaped composite columns with internally installed shape steel or FRP profiles, the composite beams are sunken type shape steel or FRP profile concrete composite beams, and the composite boards are composite boards with prestressed hidden beamsand equipped with GRC hollow box bodies; the GRC hollow box body composite boards with bidirectional prestressed hidden beams are composed of upper bidirectional slab reinforcements, lower bidirectional slab reinforcements, the bidirectional prestressed hidden beams, the GRC hollow box bodies and GRC hollow box body vertical fixing devices. According to the floor system composed of the GRC hollowbox body composite boards and the construction method thereof, the GRC hollow box bodies are arranged in floors, sound transmitting routes can be cut off through the GRC hollow box bodies evenly arranged in the floors, a good sound insulation effect is realized, and the problem of noise pollution caused by the poor sound insulation effect between the floors is solved.

Description

technical field [0001] The invention relates to a floor system in the field of civil building structures, in particular to a floor system composed of GRC hollow box composite panels and a construction method thereof. Background technique [0002] With the improvement of living standards, people have more and more demands on the functions of residential and public buildings, and buildings need to perform better in terms of sound insulation, heat insulation, large spans, and large bays. Although traditional reinforced concrete floors have matured in terms of structural form, construction technology, and technical measures, they cannot meet high-level requirements such as sound insulation and heat insulation. Especially in teaching buildings of primary and secondary schools, the sound transmission of conventional floors up and down is relatively clear. , cannot provide a clean learning environment very well, and problems such as affecting the quality of teachers' teaching have ...
