Description
(1) technical field
The present invention relates to a kind of reinforced concrete hollow floor structure, especially a kind of filler rod with expose filling box and mix the slab column system hollowcore slab that uses, belong to buildings in general structure field.
(2) background technology
At building field, along with the large-span concrete structure is increasing, increasing floor adopts the hollow floor structure technology.Sometimes in order to reduce dead load or to strengthen concrete insulation, heat insulation, sound insulation, damping effect, need to place some lightweight fillers in the concrete the inside.Replace the part concrete substantially can not affect the stress performance of structure with lightweight filler, but the deadweight that can greatly alleviate structure.
In hollow floor structure, according to the difference that is subjected to force mode, can be divided into limit supporting superstructure and post and support superstructure (challenging again rod structure) two large classes.Limit supporting superstructure is owing to having the larger bright beam of rigidity at post, and hollowcore slab is to calculate by one-way slabs or two-way slab.Post supports on the superstructure post and usually establishes dark beam, the perhaps less flat beam of rigidity, and calculating is that general the employing waited for framework method or Space finite element method.In slab column system, be divided into slab strips on columns and span centre strip according to stressed large young pathbreaker's superstructure, wherein slab strips on columns will bear moment of flexure and the 70% above shearing of 60-75%, and the span centre strip is then stressed less.
Packing material in the hollow building cover divides by geometry at present, mainly contains filler rod (comprise and fill pipe) and filling box two large classes.The section configuration of filler rod is circle or polygon or other composite figure, and the ratio of its section maximum size and minimum dimension is general≤2, the ratio of its planar dimension length and width is general 〉=and 2.The section configuration of filling box is rectangle and rectangle corner cut or chamfering, and its flat shape is generally square, also can be rectangle, usually ratio≤1.5 of planar dimension length and width.
In the prior art, the hollowcore slab that is suitable for slab column system adopts filling box mostly.For example, the thrifty academician of mark " steel concrete laced beam and close girt strip double lattice beam structure " (ZL03249445.9); Mr.'s Qiu Zeyou " a kind of cast-in-place concrete cored " (ZL200610167919.5), " a kind of cast in place reinforced bar lightweight concrete board " (ZL200410038952.9); Mr. Wang Benmiao " a kind of hollow body of cast-in-situ hollow superstructure " (ZL200910312627.X); Cheng Wen Rang professor's " without the cap concrete floor column structure " (ZL01245231.9) etc.In the prior art, when the slab column system hollowcore slab that forms with filler rod, common way is the very wide solid band of post design at both direction, just fills with filler rod at remainder.For the low situation of the less hollow rate that causes of this hollow area area, I also once proposed " a kind of hollow building cover of permanent assemblied mould arranged along beam and job practices thereof " (ZL200710123516.5), the proposition of this technology, improve the application area of filler rod in the slab column system hollowcore slab, thereby improved the hollow rate of superstructure.
According to general knowledge, the hollow rate that forms hollowcore slab with filling box obviously will surpass the hollowcore slab that forms with filler rod, but from mechanics principle, exactly because filler rod hollow rate less then concrete sectional area is relatively large, so be greater than filling box hollowcore slab, the especially shear resistance of same thickness along the supporting capacity of filler rod direction hollowcore slab.Slab strips on columns is stressed very large in slab column system, if slab strips on columns is solid concrete then dead load is very large entirely; If fill with casing at slab strips on columns, because supporting capacity (particularly shear resistance) less of this class hollowcore slab, in order to guarantee structural safety, certainly will to take the measure that improves thickness of slab or increase solid rib width, this all will cause cost to increase.Therefore adopting filler rod at slab strips on columns is the most rational from mechanics.In ZL200710123516.5, adopted filler rod beam layout in dark beam limit on the post, span centre area filling rod is pressed the form that the long span direction is arranged; Although this scheme is stressed more reasonable, still adopt filler rod in stressed less span centre strip, do not make structure obtain maximum hollow rate.
In sum, in the technology of existing slab column system hollowcore slab, also do not have a kind of technology can take full advantage of filler rod and the advantage that exposes filling box, overcome its shortcoming, form that a kind of hollow rate is large, the reasonable stress hollow floor structure.Therefore, develop a kind of filler rod and expose filling box and mix the slab column system hollowcore slab that uses and become current urgent problem.
