Background technique
At this stage, conventional building element is qualified as prefabricated member, needs to have some premises, wherein decisive
Premise be safety of structure.In the building using assembled stair, common processing mode is that stair will not participate in structure meter
It calculates, load and seismic force etc. is undertaken by the wall of surrounding, stair are only used as functional component to exist, by this optimal way, both
Ensure safety of structure, and the processing difficulty of assembly installation node can be reduced.
Summary of the invention
The purpose of the present invention is to overcome the shortcomings of the existing technology, provides a kind of precast rc slab formula stair.For
Realize above-mentioned purpose the invention adopts the following technical scheme:
A kind of precast rc slab formula stair, including it is lower bradyseism beam, lower casting frame, lower attachment beam, lateral traction hole, lateral
Towing pad, upper attachment beam, upper frame, upper bradyseism frame, precast stair frame, lower bradyseism beam are connect with lower attachment beam by connecting rod
Installation, lower casting frame are cast in inside lower attachment beam, and lateral traction hole is integrally formed on precast stair frame transverse direction pedal, laterally
Towing pad is integrally formed on the lateral grillage of precast stair frame, and lower attachment beam and the integrated molding of upper attachment beam are cast in precast stair
Frame lower end and upper end, upper frame are cast in inside upper frame.
Preferably, it is mounted with that bradyseism column, bradyseism column and bradyseism backing plate are correspondingly arranged installation built in the upper bradyseism frame.
Preferably, the upper frame is trapezoidal-structure, and front and back end casting is mounted with unidirectional reinforcing rib inside upper frame,
The casting of upper frame bosom position is mounted with two-way reinforcing rib.
Preferably, there are two the sprue gates of connection upper frame for the upper attachment beam integrated molding.
Compared with prior art, the invention has the following advantages that a kind of precast rc slab formula stair, the present apparatus are set
Meter is suitable for the precast stair installation exercise of building trade, and the built-in installation of upper and lower bradyseism beam has certain shock-absorbing function, laterally leads
The setting of pilot hole and lateral towing pad ensure that propulsive efficiency, and casting frame is improved prefabricated by sprue gate building concrete up and down
The integrally-built consistency of stair frame.
