Description
Technical field
The utility model is related to a kind of node structures of Prefabricated stacking floor, specifically say always, are a kind of the close of end fluting
Laminated floor slab connecting joint structure is spelled, belongs to laminated floor slab node technology field.
Background technology
With the continuous enlargement deepened constantly with construction scope of construction industry system reform, building industrialization is constantly by political affairs
Mansion and the concern of society, already as the developing direction of Building Trade in China.
The cast-in-place band forms of reserved 200-300mm wide are used about the connection mode of two-way laminated floor slab in the prior art,
Engineering site need to install alter-pouring strips mould plate and support, low construction efficiency；The prefabricated layer side of laminated floor slab stretches out bending reinforcing steel bar, factory
Need to muscle spacing be gone out according to difference during production and process different fixation tooth moulds, need to placed when reinforcing bar is put by root, low production efficiency；And
And largely go out muscle there are certain hidden danger to the personal safety of worker in lifting component and installation.
To sum up, laminated floor slab connecting node design construction of the prior art is low and related there are production and construction efficiency
The problem of construction safety.
Invention content
Specifically, the technical problem to be solved in the invention is：1st, the node structure of existing Prefabricated stacking floor, bottom
Portion steel bar stress stretches out Prefabricated stacking floor side, and when production needs to formulate special tooth mould to fix steel bar stress, and reinforcing bar is put
When need to be placed in by root in the tooth mould of side, greatly reduce production efficiency；2nd, it needs to install at post-cast strip during site operation
The template of 200mm wide or 300mm wide, and template vertical supporting is set up, increase the workload at scene.Meanwhile it is mixed at post-cast strip
Surface perception is inconsistent after construction with precast floor slab bottom surface for solidifying soil bottom surface, and surface is also difficult to ensure that and flushes, and the later stage increases a large amount of
The workload manually smoothed out；3rd, the close application for spelling laminated floor slab has larger limitation in the prior art：1. the thickness of in-situ layer
≥80mm；2. Prefabricated stacking floor is necessary for truss bars floor.
The present invention takes following technical scheme：
A kind of close spelling laminated floor slab connecting joint structure of end fluting, the end of precast floor slab opens up the rectangle not penetrated
Slot, rectangular channel is grown along plate to be arranged at intervals, and laminated floor slab bottom steel bar stress does not stretch out plate side in preformed layer；Scene splicing
When：Close match-place connects between adjacent laminated floor slab, the rectangular channel docking of the adjacent laminated floor slab of edge joint position, is set in edge joint position rectangular channel
Additional bar 1 is put, 1 both ends of additional bar are folded upward at；The area of the additional bar 1 is not less than equidirectional bottom stress
The area of reinforcing bar；The non-rectangle groove location Additional vertical of edge joint position is vertically set in the distributing bar 7 of piece with 7 direction of distributing bar
Put elongated reinforcing bar 8.
Further, distributing bar 7 and the lap of splice of every piece of laminated floor slab are not less than 15d, d=distributing bar diameters.
Further, the angle between 1 both ends of additional bar are folded up position and additional bar ontology is sharp
Angle.
Further, the height of the additional bar 1 is high higher than the slot of rectangular channel.
The beneficial effects of the utility model are：
1) bottom steel bar stress does not stretch out Prefabricated stacking floor side, does not need to special tooth mould, and bottom reinforcement bars can during production
It is directly integrally positioned in mold with making bar-mat reinforcement, great improving production efficiency；
2) during site operation, Prefabricated stacking floor is directly close to be stitched together, and sets post-cast strip without staying, is poured after reducing scene
With formwork and the work supported is set up, promotes site operation efficiency；
3) effective height that additional bar does not reduce edge joint position section is placed in edge joint position rectangular channel, ensure that laminated floor slab
In the bearing capacity of edge joint position, so as to break through limitation of the prior art for cast-in-place layer thickness >=80mm, meanwhile, additional bar it is curved
Hook and accessory configurations reinforcing bar ensure that the good anchoring property of additional bar, breach Prefabricated stacking floor and are necessary for truss
The limitation of reinforced concrete floor slab.
4) band crotch additional bar connection length is short compared with lapped length of steel bar in the prior art in slot, and reduces additional
The connection quantity of reinforcing bar, saves material utilization amount and scene is artificial.
