Further, on the filler of floor support plate and the bonding surface of profiled sheet, be suppressed with reinforcing rib, described reinforcing rib extends along plate length direction.
Further, described filler is foam concrete, and in the cavity of described profiled sheet, filling deadweight is 300 ~ 400kg/m 3the foam concrete of left and right.
Further, described additional steel are reinforcing bar or steel plate, and its additional position can be that rib of slab outward also can in rib of slab.
The utility model also provides a kind of composite floor system of back-buckling type floor support plate, it is characterized in that, it comprises described floor support plate, and floor support plate laid by girder steel, weld stud in the rib of slab of the vertical setting of floor support plate, in order to floor support plate and girder steel to be fixed; According to concrete engineering design document, floor support plate lays reinforcing bar, after building pea gravel concreten, form composite floor.
The beneficial effects of the utility model are compared with prior art: the utility model is relative to existing composite floor, and deadweight minimizing about 50%, greatly reduces geological process, overall structure and foundation cost are significantly reduced.Compoboard soffit is foam concrete face, and decoration of directly can plastering, saves furred ceiling.The temporary support in work progress can be cancelled; Greatly improve the fire prevention of floor, insulation, sound insulation value; Simple construction method, decreases working procedure, reduces floor cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model back-buckling type floor support plate;
Fig. 2 is the cross section structure schematic diagram of the profiled sheet of the utility model back-buckling type floor support plate;
Fig. 3 is the structural representation of the utility model composite floor system.
Detailed description of the invention
Below in conjunction with accompanying drawing, to above-mentioned being described in more detail with other technical characteristic and advantage of the utility model.
Refer to shown in Fig. 1, it is the structural representation of the utility model back-buckling type floor support plate, and the utility model floor plates comprises profiled sheet 17 and foam concrete 13, and wherein, profiled sheet 17 is a ribbed plate, and it is as the main body of floor support plate load; Filling foam concrete 13 in profiled sheet 17 lower cavity, in order to realize the requirement of the functions such as insulation, sound insulation, fire prevention, sound-absorbing.
In the utility model, foam concrete 13 can adopt other light material to be composited.
In the utility model, profiled sheet 17 is compressing through special equipment, and it is about 1.0mm thick and thin wall steel plate; At the upper shed face welding wire truss 11 of profiled sheet 17, steel wire truss 11 is arranged along plate length direction; On the foam concrete 13 of floor support plate and the bonding surface of profiled sheet 17, be suppressed with reinforcing rib 12, described reinforcing rib 12 extends along plate length direction, and direction as indicated by the arrows in the figure, in order to reinforce the rigidity of floor support plate thin-walled steel plate.
Shown in Fig. 2, it is the cross section structure schematic diagram of the profiled sheet of the utility model back-buckling type floor support plate, steel 16 are added in rib of slab 14 side of the vertical setting of the profiled sheet 17 suppressed or bottom welding, these additional steel can be reinforcing bar or steel plate, and attached welding position is put and can be positioned at die mould rib of slab outside with inner; At the attached welding steel silk netting 15 in the under shed face of profiled sheet 17.
In the present embodiment, the width of the rib of slab 14 of described profiled sheet 17 is at about 50mm, and rib of slab height is at about 50 ~ 80mm.Profiled sheet 17 is applicable to general steel plate, galvanized steel plain sheet, color painted steel strip with material and can meets other sheet metal of stress performance requirement.
In the present embodiment, the cross sectional shape of profiled sheet 17 is by the alternate rectangle of rib of slab 14, also can be other shape, only need meet following stress characteristic.
In the utility model, in the cavity of the above-mentioned profiled sheet 17 completed, filling deadweight is 300 ~ 400kg/m 3the foam concrete 13 of left and right or other light material, steel fabric sheet 15 can make foam concrete 13 and profiled sheet 17 well be combined with each other, and the rigidity of profiled sheet can be strengthened, due to the lightweight of foam concrete, insulation, sound insulation, fireproof are functional, sheet material are achieved integrate lightweight, high-strength, insulation, fire prevention, sound insulation value.
Refer to shown in Fig. 3, it is the structural representation of the utility model composite floor system, above-mentioned floor support plate laid by girder steel 34, weld stud 32 in the rib of slab 14 of the vertical setting of floor support plate, floor support plate and girder steel 34 are fixed, according to engineering design requirements, floor support plate lays reinforcing bar, the pea gravel concreten 31 of building corresponding label forms composite floor.
When the composite floor formed with floor support plate, relative to traditional composite floor, floor support plate is placed upside down, namely so-called " left-hand thread " formula; Tensile reinforcement required in composite floor is welded in floor support plate rib of slab bottom so that the form of additional steel is attached, by the perpendicular rib of profiled sheet, the steel plate of pressurized is combined bending resistance together with the additional steel coordination of tension, improve rigidity and the supporting capacity of floor support plate self greatly.
The load of the floor support plate in the utility model is characterized as: add steel tension by floor coordinate the to remain silent profiled sheet resistance to compression in face and floor bottom surface, make tension and resistance to compression work in combination resist torque; Filling foam concrete or other light material in plate lower cavity, for ensure foam concrete well with profiled sheet compound, at the attached welding steel silk netting in the lower openings face of profiled sheet.
The load of composite floor system is characterized as: effectively concrete and floor support plate are combined by the steel wire truss in floor support plate upper shed face, formed with the load feature of adding steel tension and floor support plate top steel plate and concrete compression at the bottom of floor support plate plate, form the bending bearing capacity of composite floor with this.
Foam concrete in the utility model or other light material, be only the filler improving the performances such as insulation, sound insulation, fire prevention, do not participate in load, under having other engineering measure to realize the prerequisite of its function, can save.
The foregoing is only preferred embodiment of the present utility model, is only illustrative for utility model, and nonrestrictive.Those skilled in the art is understood, and requires to carry out many changes to it in the spirit and scope that limit, amendment in utility model right, even equivalent, but all will fall in protection domain of the present utility model.
