Description
The present invention relates to a kind of steel bar concrete tubulose cassette ceiling.
At present, in the prior art, hollow pipe component is generally paper tube, plastic pipe, metal bellows or cavity hard thin-wall members etc., and these hollow pipe components mainly consider to find time concrete, alleviate floor weight.Existing steel bar concrete tubulose cassette ceiling, comprise beam between wall column, the vertical rib of cast-in-situ reinforced concrete, cast-in-situ reinforced concrete upper flange, cast-in-situ reinforced concrete lower wing plate, hollow section, hollow section is alternately between vertical rib of cast-in-situ reinforced concrete or wall column between the beam, it on it cast-in-situ reinforced concrete upper flange, it is the cast-in-situ reinforced concrete lower wing plate down, there is plug at the hollow section two ends, and the cross sectional shape of hollow pipe component can be circle, square or other is special-shaped.This class cassette ceiling is owing to the concrete in the plate is found time by hollow pipe component, vertically there is cast-in-situ reinforced concrete to indulge rib in the outside along pipe, laterally then there be not Force transmission parts, or only have prevent that wet concrete or cement paste from entering two seal plug, cause existing cassette ceiling in the effect that laterally can't bear complicated pulling force, pressure, shearing, flush shear force, moment of torsion etc., make cast-in-situ reinforced concrete tubular, hollow floor two direction rigidity great disparities bigger, and can't form the two-way concrete slab concrete tubular, hollow floor of well word rib equivalence.This kind cassette ceiling is as comparing with the two-way ribs plate floor, then exist hollowcore slab thickness big, the steel bar concrete consumption is big, and from great, deflection deformation is big, shearing resistance, torsional property are poor, Cast-in-place concrete weakness easy crack in bottom flange on the hollow section, shock resistance is poor, and two-way stiffness difference is big, the pipe cracky, the Cast-in-place concrete leakage loss is big, problems such as cost height.Therefore develop a kind of new reinforcing steel bar concrete tubular, hollow floor for being badly in need of.
The object of the present invention is to provide a kind of steel bar concrete tubulose cassette ceiling, it is little to have hollowcore slab thickness, characteristics such as the steel bar concrete consumption is little, and is in light weight, and deflection deformation is little, and the shearing resistance torsional property is strong, is difficult for the crack, and bidirectional stress power transmission difference is little, and shock resistance is strong, and cost is low.
Solution of the present invention is on the basis of existing technology, comprise beam between wall column, cast-in-situ reinforced concrete is indulged rib, the cast-in-situ reinforced concrete upper flange, the cast-in-situ reinforced concrete lower wing plate, hollow section, hollow section is alternately between vertical rib of cast-in-situ reinforced concrete or wall column between the beam, it on it cast-in-situ reinforced concrete upper flange, it is the cast-in-situ reinforced concrete lower wing plate down, there is plug at the hollow section two ends, it is characterized in that hollow section is a combined hollow tube, combined hollow tube contains a slice stiffening rib and the above hollow body of at least two joints at least, hollow body docks connection on stiffening rib, stiffening rib combines with the vertical rib of cast-in-situ reinforced concrete, constitutes two-way dark close rib structure.Like this, hollow section is a combined hollow tube, and the vertical rib combination of stiffening rib in it and cast-in-situ reinforced concrete constitutes two-way dark close rib structure, eliminate the horizontal no primary structure member of cassette ceiling behind the hollow section pore-forming in the past and the defective of cracking resistance structure, improved lateral stiffness and the intensity of cassette ceiling.Characteristics such as it is little also to have hollowcore slab thickness simultaneously, and the steel bar concrete consumption is little, and is in light weight, and deflection deformation is little, and the shearing resistance torsional property is strong, is difficult for the crack, and bidirectional stress power transmission difference is little, and shock resistance is strong, and cost is low have reached purpose of the present invention.
In addition, the present invention also has following advantage:
1, can freely separate the interior space, make indoor hommization, the personalized designs of meeting of building;
2, flat board need not furred ceiling;
3, various pipelines are easy for installation;
