To achieve the goals above, a kind of multifunctional precast floor, it include the pouring layer set gradually from bottom to up, every Sound insulating layer, waterproof layer and protective layer, the pouring layer include bar-mat reinforcement and concrete substrate, the length of the concrete substrate Direction is equipped with several circular hollow ducts through both ends, and the bar-mat reinforcement is embedded in concrete substrate, and vertical in bar-mat reinforcement Reinforcing bar extends along the length direction of concrete substrate and stretches out 60~100mm respectively from the both ends of concrete substrate, and one end is stretched The longitudinal bar bending hook at a right angle gone out, the longitudinal bar that the other end stretches out are bent into round hanging sleeve.

In order to realize that structure, effect optimization, further step be：It is equipped between the sound-insulating layer and waterproof layer Separation layer.

The separation layer uses non-woven polyester fabric cloth.

The sound-insulating layer uses aluminosilicate fiber cotton.

The waterproof layer uses polyethylene polypropylene fiber composite sheet and its thickness >=0.5mm.

The protective layer is cement mortar protective course.

The utility model compared with prior art caused by advantageous effect：

(I) the utility model stretched out respectively along the both ends of concrete substrate length direction using reinforcing bar and be bent into hook and Hanging sleeve, when installation, the hook of one of precast floor slab can stretch into the hanging sleeve of docking precast floor slab, can realize contiguous prefabricated building Plate is connected in one, to improve the integrated connection intensity of precast floor slab, effectively enhances the anti-seismic performance of building；

(II) the utility model is equipped with several circular hollow ducts through both ends using the length direction of concrete substrate, The dead weight of building can greatly be mitigated, construction cost is reduced, construction investment is greatly reduced, be widely used in skyscraper use；

(III) the utility model uses pouring layer, sound-insulating layer, waterproof layer and the protective layer set gradually from bottom to up, Its bearing capacity is strong, and thermal coefficient is small, and heat preservation and soundproof effect is good, and water absorption rate is low, to realize that collection heat preservation, sound insulation, waterproof etc. are more Function solves the problems such as roofing is warm, splits, leaks, reduces the construction link that roofing need to carry out thermal-insulating waterproof, effectively drop in one Low building integral construction cost；

(IV) the utility model increases the knot of hook and hanging sleeve using setting waterproof sound-insulating layer and at floor both ends Defect of the structure to overcome the poor and waterproof thermal-insulated effect of prior art anti-seismic performance poor can improve between contiguous prefabricated floor It is connected intensity, the construction links such as waterproofing and thermal insulation of roofing can be reduced, reduces construction investment 10~15% on the whole, and whole Body is scientific and reasonable for structure, simple and compact, easy to install and use, has significant economic benefit and social benefit.

The utility model is widely used in all types of industries and civil buildings match.

The utility model is described in further detail with reference to the accompanying drawings and examples.
