Background technique
The formwork erection of cast-in-situ floor and dismounting are extremely complex, take time and effort, not only seriously restrict production efficiency, cause
The raising of construction cost, and increase labor intensity, aggravating laboring environment.
To simplify technique, people attempt to use permanent template (or solid model), the concrete of permanent template and cast in situs
(cast-in-place concrete layer) is consolidated, and forms a part of floor structure, thus at least eliminates form removable workload,
In more successful technology include profiled sheet and steel bar girder concrete folding plate.Since the material feature of profiled sheet is uncomfortable
People's living habit and fitting-up requirement are answered, and there are many defects such as perishable and construction inconvenience, adaptation occasion is few, at present
Often it is only used for the not high industrial premises of means suitable.
Steel bar girder concrete folding plate is that the concrete layer of flooring is divided into two-step pouring, first with steel bar girder and under
Layer reinforcing bar is skeleton, pours out lower concrete layer in factory, forms precast slab, and the top of steel bar girder is from concrete
The upper surface of native plate is exposed, and is lifted by the exposed reinforcing bar that winds up, and bed die is used as after being installed in place at the scene, carries out second
Secondary concreting, cast-in-place upper concrete layer and prefabricated lower concrete layer consolidation are integral, form laminated floor slab.In addition,
For technologic convenience, upper one layer of metal plate can also be directly welded in the bottom of steel bar girder, using the metal plate as in advance
Thus the bed die that concrete layer processed pours makes the bottom of precast slab with one layer of metal plate, after the completion of cast in situs,
This layer of metal plate is removed again, and close the truss bars exposed because of steel plate dismounting with glue mud isocolloid material is mixed.
Existing steel bar girder concrete folding plate significantly reduces the complexity that Site Template installs, and without carrying out

In turn but also the cost of this precast concrete is much higher than the cost of poured in place concrete, and significantly increases transport and deposit
Other relevant costs such as storage；Second is that connection reinforcing bar (usually by concrete layer longitudinal reinforcement and/or transverse steel from
End or side extend out) at the scene install when often by the reinforcing bar on support (usually beam or wall through arrangement of reinforcement)
It hinders, because connection reinforcing bar is fixedly arranged on concrete layer, exposed parts are shorter, and it is not flexible, to bypass the resistance of support reinforcing bar
That keeps off is difficult, and reinforcing bar will be connected by, which often having in practice, cuts off, and thus can seriously affect bonding strength；Third is that especially
For two-way slab, the hoard strip that gap is formed between precast slab is wider, still will cause biggish branch striking job
Amount；Fourth is that adhesion strength is significantly lower than the concrete strength of one-stop operation between prefabricated and cast-in-place both concrete layers, building is influenced
Plate quality, and be easy to crack occur.In addition, when metal plate is arranged in the bottom of precast slab, although facilitating or simplifying
Related process, but the workload that metal plate is removed is very big, and the metal plate after dismounting usually there will be a large amount of damages, influences again
It uses, causes certain waste, can't see after removing exposed truss bars after metal plate although blocking from appearance, block material
