At present in multilayer and high-rise steel structure civil buildings, the staircase boards of staircase mostly use cast-in-place concrete stair
Plate needs to carry out template at the scene in construction, progress reinforcing bar binding, after casting concrete, carries out the maintenance of certain time, this nothing
It doubts and just extends the duration, installed with main body steel construction extremely asynchronous；Building waste is generated in work progress simultaneously to be easy to surrounding
Environment pollutes, and affects the working environment of worker.
Utility model content
The purpose of this utility model is to solve the above-mentioned problems in the prior art, and it is simple to provide a kind of constructing operation,
Short construction period greatly reduces garbage discharge amount, reduces the assembly concrete stair of airborne dust and noise circumstance pollution
Structural system.
To achieve the above object, the technical solution of the utility model is：A kind of structural system of assembly concrete stair,
Including four steel core concrete columns, more frame girder steels, more platform girder steels, polylith landing slab, polylith prefabricated reinforced concrete
Step plate and handrail；Steel core concrete column is to be supported on the quadrangle of stair in steel pipe made of cast-in-place concrete；Per floor
The position of platform lower end of ladder have four frame girder steels between being rigidly fixed in four steel core concrete columns, a platform girder steel and
One piece of landing slab, platform girder steel both ends are hingedly fixed on two opposite frame girder steels, and four end of landing slab is respectively articulated with fixation
On the three frame girder steels and a platform girder steel of its lower end；The upper end of prefabricated reinforced concrete step plate is two or two reserved
A above bolt connecting hole, the upper end rides over and is fixed in upper platform steel beam flange by each bolt, filled out on side wall
Poly- stupid plate is filled, and grouting material is filled in poly- gap between stupid plate and landing slab；The lower end of prefabricated reinforced concrete step plate
There are the overlap joint position wider than upper end, which is supported on the landing slab of lower layer, gathers
Tetrafluoroethene backing plate is pasted and fixed on steel bar truss floor support plate.
Preferably, the bolt upper end of the fixed prefabricated reinforced concrete step plate and upper platform steel beam flange is inoculated with
Mortar blocks.Bolt is avoided to get rusty.
Preferably, the poly- grouting material upper end between stupid plate and upper platform plate is marked with sizing material.Sizing material is to grouting material
Play better sealing process.
Preferably, the platform girder steel is steel I-beam.Support force can be met, saving material is artificial, shortens the construction period,
Environment is protected again.
Preferably, the landing slab is steel bar truss floor support plate.Support force can be met, it is easy for construction to shorten the construction period,
Environment is protected again.
The utility model realizes the assembly prefabricated reinforced concrete step plate in multilayer and high-rise steel structure civil buildings
Purpose maximize favourable factors and minimize unfavourable ones the characteristics of not only having given full play to the material advantage of steel construction, but also played concrete component low cost.Main body
Using steel frame structural system, Local Members use precast reinforced concrete structure, both solved concrete component scene formwork,
The problem poured improves prefabrication and assembly construction rate, and then realizes whole prefabrication and assembly constructions of staircase structural elements, constructing operation
Simply, short construction period, the purpose synchronous with main body steel construction installation, and reached the cost for reducing steel structure system, also solve
Steel structure system fire resistance of having determined is poor, and structure itself heat preservation is poor, easy the shortcomings that forming heat bridge.The utility model greatly reduces
Garbage discharge amount reduces airborne dust and noise circumstance pollution.
