Description
Technical field
This utility model relates to building element technical field, in particular to a kind of precast concrete composite floor plate.
Background technology
Wallboard is formed the building structure of bearing system by wall and floor.Supporting member both made by wall, made again the partition in room,
It is the most frequently used in residential architecture and the version of less expensive.Shortcoming is that the motility that indoor plane is arranged is poor, for overcoming this
One shortcoming, currently develops to large bay direction.Panel structure is used for house, apartment, can also be used for office building, school etc.
Utilities building.The load bearing wall of panel structure can be made with brick, building block, prefabricated or cast-in-place concrete.
Wherein, floor prefabricated reinforced concrete or prestressed concrete are made, and are divided into wood by the difference of material therefor
Floor, brick arch floor, reinforced concrete floor, steel liner plate floor, be divided into prefabricated assembled, cast-in-place whole by the difference of processing technology
Body formula and assembled integral floor.Composite floor plate is the assembled integral being composited by precoated plate and cast-in-situ steel reinforced concrete layer
Floor, owing to assembled integral composite plate is provided simultaneously with precoated plate easy construction and the advantage of Bars In Poured Concrete Slab good integrity, improves
Construction speed, shortens construction period.
According to the difference of section form, conventional composite plate has cored slab type composite plate, bottom plate combined plate with ribbing and solid
Template composite plate, the deadweight of hollow template composite plate is little, it is adaptable to longspan structure, but thickness of slab is thicker, and shearing resistance, shock resistance
Difference；Bottom plate combined plate with ribbing due under the effect of construction loads and working load composite plate base plate be provided that reliable rigidity and
The reason of bearing capacity, so eliminating substantial amounts of template and support, saves the consumption of steel and timber, but traditional type band
The bottom plate combined plate of rib has new-old concrete intersection and is easily generated crack, composite plate rigidity and the shortcoming of globality difference；And it is real
One-way slabs in core, stress performance and economic performance are all not as good as two-way slab, and prefabricated hollow floor does not insulates against sound, the most heat insulation, anti-
Shock stability is bad, easy to crack after floor piece, infiltration.How can both meet rigidity, bearing capacity, shock resistance, can save again
Amount of reinforcement, reduction thickness of slab and composite plate dead weight become the key of composite plate research.
