Abstract
The utility model provides a PCM cast-in-situ concrete steel ribs hollow floor, which is characterized in that the inner part of the prepared PCM cast-in-situ concrete steel ribs hollow floor includes hollow cavities and steel ribs , wherein, the hollow cavities are formed by drawing out mandrels. The PCM cast-in-situ concrete steel ribs hollow floor has the advantages of large carrying capacity, good earthquake resistance, convenient construction, low cost, light self-weight, no internal mold, and good stress performance, etc., and is particularly suitable for the cast-in-situ floors of high-rise buildings and longspan structures.
Description
Affiliated technical field
The utility model belongs to a kind of PCM cast-in-situ reinforced concrete reinforcing bar hollowcore slab, is specially adapted to the cast-in-situ floor of highrise building and longspan structure.
Background technology
At present, cast-in-situ reinforcing steel bar concrete hollow slab mostly adopts plain bars concrete structure and prestress concrete structure, and its supporting capacity, anti-seismic performance, difficulty of construction more and more can not satisfy highrise building and large span.The requirement of structural development.And cast-in-situ hollow building roof mostly adopts and includes the permanent tyre mould structure, causes the valency height, pass realification difficulty.
Summary of the invention
The purpose of this utility model just provide that a kind of supporting capacity is big, anti-seismic performance good and easily cost low, from heavy and light, no internal mold, PCM Cast-in-place concrete reinforcing bar hollow building cover that stress performance is good.
PCM Cast-in-place concrete reinforcing bar hollow building cover of the present utility model is characterized in that the cast-in-situ reinforced concrete inside of making contains core-drawing pore-creating cavity and reinforcing bar.
The utility model has been owing to adopted section steel beam to become pore structure with clumsy core, has that supporting capacity is big, anti-seismic performance good, easy construction, and cost is low, from advantages such as heavy and light, no internal mold, stress performance are good, is specially adapted to the hollowcore slab of highrise building and longspan structure.
Description of drawings
The utility model is described in further detail below in conjunction with description of drawings:
Fig. 1 is the perspective view of the utility model embodiment one.
Fig. 2 is the perspective view of the utility model embodiment two.
Fig. 3 is the perspective view of the utility model embodiment three.
Fig. 4 is the perspective view of the utility model embodiment four.
The specific embodiment
Shown in Fig. 1-4, the utility model is made up of reinforcing bar 1, concrete 2, cavity 3, reinforcing bar 4.Among the embodiment that Fig. 2 provides, described reinforcing bar 4 places under the reinforced concrete hollow floorslab by profiled sheet 5, forms bright beam hollow building cover.The embodiment that Fig. 1,3,4 provides, described reinforcing bar 4 is embedded in the steel bar concrete.Among Fig. 1 reinforcing bar 4 vertically and the geometric center lines of cavity 3 in the same way.Reinforcing bar 4 is vertically vertical with the geometric midline of cavity 3 among Fig. 3,4.Among the embodiment of Fig. 4, have profiled sheet 5 under its hollow building cover, this structure is convenient to construction and is made, the profiled sheet 5 permanent reservations that formwork is used.
In the above-described embodiments, reinforcing bar 4 all can adopt " L ", " I ", " [", " mouth " type shaped steel, the special-purpose shaped steel that also can adopt the non-type deformed steel or weld, be rolled into the steel material of typing.In addition, the cavity of described cavity 3 after for the mould of loosing core.
