Floor system comprising box beams and construction method thereof

Abstract

The invention relates to a floor system comprising box beams and a construction method thereof. The floor system comprises stand columns, column caps, the box beams and floors, wherein the column caps are located at the tops of the stand columns; each box beam is erected between the two corresponding adjacent column caps; the floors are arranged between the box beams to form a plurality of grid structures; and the floors are located in grids. According to the floor system comprising the box beams, through a beam and slab structure system where the box beams, slabs and the column caps are jointly stressed, the requirement of the standard for serving as an embedding end of a basement roof is met, the floor height is effectively reduced, the beam height is smaller than that of an existing beam floor, the excavation amount of a basement is reduced, and cost is reduced; and in addition, webs of the hollow beams serve as supports of the floors, the peak value of the bending moment of the floors is reduced, floor reinforcing bars and slab spans are reduced, the self weight of the structure is reduced, and the structural rigidity is improved. The comprehensive manufacturing cost of the structure system is lower than that of a common beam and slab system, and the structure system has good applicability to basement structures with embedding requirements in actual structure application.

Description

technical field [0001] The invention relates to a floor system including box girders and a construction method thereof, in particular to a floor system suitable for basements and large-span column net structures. Background technique [0002] Common floor systems include beam-slab structure system, beamless floor system, slab with haunches, well-shaped beams, one-way double-beams, one-way secondary beams, cross-beams, hollow floors, etc. The advantages of the beam-slab structure: 1. The force is clear; 2. The out-of-plane rigidity of the structure is relatively good, and there is no limit in use. Disadvantages of the beam-slab structure: 1. Because the effect of the slab cannot be fully considered according to the classic beam-slab force theory, the beam section is very large, resulting in a higher floor height of the basement and an increase in the cost of vertical components; 2. Due to the height of the floor Increase, increase the water buoyancy of the bottom plate, ther...
