Abstract
The present invention discloses overlapped hollow floor system after a kind of partial precast assembled, including cast-in-situ floor base plate, cast-in-place girt strip expanded metals lattice and prefabricated flat board.First branch bed die and beam rib side form, prick base plate and girt strip reinforcing bar, then hollow building cover base plate and girt strip concrete are poured, construction joint is left to top board bottom, then the flat board corresponding with each hollow dimension that will be prefabricated into advance is lifted to girt strip top, the vertical muscle of stress being connected with dark beam is placed in each girt strip correspondence position again, finally pour each flat board beam on alternate frames position is secondary, maintenance is completed.The present invention cancels interior mold materials in hollow building cover, using secondary two kinds of novel hollow building cover structures for overlapping and pouring shaping during construction.The structural shape will can solve the foregoing whole issue of conventional hollow superstructure presence, while not increasing difficulty of construction also.
Description
Technical field
The present invention relates to assembled architecture field, particularly hollow building cover.
Background technology
Hollow building cover is because structure height is small, space stiffness big, the design cost more more economical than common rib-beam floor frame is big
There is preferably applicable prospect in span garage, business, square and part large panel structure.
But existing hollow building cover needs to use internal model (full cast-in-place concrete), there is following asking during practice of construction
Topic：
(1) the ununified specification standards of the interior mold materials of each hollow building cover internal model supplier offer, current hollow building cover
Refinement can only be performed according to its unique material by internal model supplier, and internal model supplier generally by construction general contracting unit
It is determined that, do not go out in construction drawing, general contracting unit of constructing it is undetermined in the case of, it is desirable to it is thin that internal model supplier carries out hollow building cover in advance
It is unpractical to change design, and disorder has been occurred as soon as so in management program；
(2) internal model supplier carries out monopolization to respective internal model supply material, therefore internal model Master Cost is higher, also during implementation
Pay general contracting unit a certain proportion of construction cooperation expense, significantly increase engineering cost；
(3) full cast-in-place concrete hollow building roof underplate concrete is difficult to pour closely knit, uniform, greatly influences engineering matter
Amount；
(4) due to the engineering flat shape such as most of garage and irregular, the specification of interior mold materials limits hollow
Hollow position is freely arranged in superstructure, causes many positions such as corner to make solid, causes engineering cost to increase more.
(5) full cast-in-place concrete hollow building roof situ wet operation is big, and the construction period is more long, and industrialization degree is relatively low.
The content of the invention
In being constructed present invention aim to address existing hollow building cover, a series of problems brought using internal model.Proposition takes
Disappear interior mold materials in hollow building cover, using secondary two kinds of novel hollow building cover structures for overlapping and pouring shaping during construction.
The technical scheme used to realize the object of the invention is a kind of such, overlapped hollow after partial precast assembled
Superstructure, it is characterised in that:Including cast-in-situ floor base plate, cast-in-place girt strip expanded metals lattice and prefabricated flat board.The cast-in-situ floor base plate and
Cast-in-place girt strip expanded metals lattice one-time-concreting shaping.The cast-in-place girt strip expanded metals lattice are the crisscross lattice of cast-in-situ floor plate upper surface
Sub- shape floor, each grid one piece of prefabricated flat board of correspondence.
The each piece of prefabricated flat board closes a upper end opening for grid.There is seam between adjacent prefabricated flat board
Gap, these gaps form the preset slot raceway groove grid of crisscross clathrate.It is below the preset slot raceway groove grid
The upper end of cast-in-place girt strip expanded metals lattice.In the prefabricated prefabricated flat board, it is necessary to reserved steel bar joint, these splices are positioned at institute
In stating preset slot raceway groove grid.
The some lacing wires of configuration in the cast-in-place girt strip expanded metals lattice.The vertical muscle of laying stress in the preset slot raceway groove grid.This
Beam/post/wall connecting around one end of a little vertical muscle of stress and preset slot raceway groove grid.Catch on cast-in-situ floor in the lacing wire lower end
Reinforcing bar, upper end in base plate catch on the vertical muscle of stress.To carried out in the preset slot raceway groove grid it is secondary pour, after the completion of maintenance,
That is the prefabricated assembled rear overlapped hollow floor system of forming part.
Further, the surrounding of the prefabricated flat board is domatic.
Further, when laying stress indulges muscle in preset slot raceway groove grid, each raceway groove of preset slot raceway groove grid
Lay the vertical muscle of a stress in two ends.
Further, one end of each vertical muscle of stress is connected with the dark beam around preset slot raceway groove grid.
Further, it is dark beam and column body around the cast-in-place girt strip expanded metals lattice.The institute of cast-in-place girt strip expanded metals lattice surrounding configuration
Prefabricated flat board is stated to be contacted with these dark beam and column bodies.
Further, in the cast-in-place girt strip expanded metals lattice, each piece lacing wire of crisscross point configuration.
The solution have the advantages that it is unquestionable, cancel interior mold materials in hollow building cover, using secondary folded during construction
Conjunction pours two kinds of novel hollow building cover structures of shaping.The structural shape will can solve the foregoing whole of conventional hollow superstructure presence
Problem, while not increasing difficulty of construction also.
Advantages of the present invention is as follows：
1) due to cancelling interior mold materials, engineering cost reduction.Garage, large span business can use such superstructure, overall
Cost saving is big.
2) save the duration, prefabricated flat board can separately select field construction, lifting short time limit, expense simultaneously with the cast-in-place base plate of superstructure
It is low.
3) the cast-in-place part of hollow building cover is identical with common rib-beam floor frame, easy construction, without setting internal model Anti-floating reinforcing steel bar etc.,
Superstructure base plate can pour closely knit, and construction quality is more easy to be guaranteed.
4) hollow body flexible arrangement, its position and size can freely be arranged according to the concrete condition of plane.In sketch plate area
Domain, hollow rate is higher, and concrete material is more saved, and can give full play to the advantage of hollow building cover.
5) after method for designing is ripe, hollow building cover design is completed in the lump by building design units, reduces design management
Link.
