Description
Technical field
This utility model relates to a kind of prestressing force assembled stair, belongs to building industrialization field (building).
Background technology
The form that assembled staircase splits is more and more diversified, and connected mode is different.But the most all exist
Some problems: 1. construction weight is big, project under construction needs tower crane of upgrading, and increases cost；2. a lot of abnormity components, component after splitting
The bad production of factory；3. connect node many, the on-the-spot bad installation of project.Need a kind of high standardization of design, symmetry attractive in appearance, convenient
The stair of construction, assembled stair as splicing furniture.Chinese patent CN200510200224.8 discloses a kind of assembling entirety
Formula stair and preparation method thereof, particularly a kind of assembled integral spiral stairway and preparation method thereof, it is in advance by every grade of step
It is fabricated to box shape structure, and it is whole by the method for bolt or welding, the step of box shape structure to be connected to an assembling
Body formula stair, its integrally assembling staircase can be straight stair or spiral stairway shape.This patent eliminates making conventional concrete
Making template, the wiretie that must carry out during stair, build and dismantle the work such as scaffold, maintenance, therefore substantially reduce
Make the duration, reduce cost of manufacture, have simple in construction, cheap, make that the duration is short, it is extensive easily to realize industrialization
Produce and fabrication and installation all facilitate easy feature.But, this patent is primarily adapted for use in spiral stairway, and assembled, relies on phase
Adjacent two box shape structures are connected with each other and form, and the rear connecting plate of next stage step is connected with the front of upper level step by bolt
Plate is formed by connecting integrally assembling staircase, and the rear connecting plate of its upper level step is connected with the floor of building, this connection
Mode structural stability is the highest, and assembling structure is complicated, and versatility is poor.
Utility model content
This utility model aims to provide a kind of prestressing force assembled stair, and these stair use prestressing force gangboard, reduce prefabricated
The thickness of gangboard component, thus reach the effect of loss of weight.Further, gangboard and the most prefabricated, installation of marking time, the structure after fractionation
Part lightweight, reduces load to greatest extent, it is possible to reach mass production, efficient assembling construction, can gamut promote mesh
's.
To achieve these goals, this utility model be the technical scheme is that
A kind of prestressing force assembled stair, including gangboard and the multistage unit of marking time being fixed on gangboard；It is characterized in that,
Every grade of unit of marking time includes mark time panel and the side plate of marking time supporting panel of marking time as tread；Described gangboard is prestressing force ladder
Plate, gangboard thickness is 80mm-140mm.
Prestressing force gangboard described in the utility model is similar to pre-stress floor, refers in process of production to steel bar stress
Apply tension stress, cracking with the concrete preventing gangboard operationally advancing side, also give full play to tension steel simultaneously
The effect of muscle, saving steel.
Thus, this utility model uses prestressing force gangboard, on the premise of structural strength is equal to, efficiently reduces gangboard

Marking time on panel of step unit.
So that the installation process of stair is more simple and convenient, and can come into operation, preferably adjacent two after installation at once
Level is marked time in unit, and upper level is marked time, and to have lower limit domatic for the side plate bottom of marking time of unit, and next stage is marked time the marking time of unit
Panel the inner has and domatic with described lower limit coordinates spacing upper limit domatic.Thus, it is provided with spacing due to the bottom of gangboard
Platform, it is only necessary to adjust the right position marked time and can complete the installation of marking time of next stage, and mark time and will not move easily, install
Can use after completing at once.Further, the lower end of described gangboard has and marks time the spacing of unit for positioning subordinate
Platform, and mark time the spacing domatic of side plate of marking time of unit of subordinate be arranged on inside described limiting stand.Can certainly be spacing
Opening translot on platform, the riser part of marking time of unit of then subordinate being marked time realizes spacing in snapping in translot, the most this structure
The most more complex.Thus, during installation, by prefabricated gangboard and mark time and be transported to scene, first lifting stair gangboard
And install fixing, then inject grouting material in the installing hole of marking time of the next stage on gangboard, will mark time and be placed on gangboard,
The latch reinforcing bar marked time is made to insert in the installing hole of gangboard, owing to the bottom of gangboard is provided with confined planes, it is only necessary to adjustment is marked time
Right position can complete the installation of marking time of next stage, and mark time and will not move easily, can use after installation at once.
Installing one-level again to mark time, be provided with bound plane owing to marking time, the upper limit plane of next stage can be marked time as upper level
Confined planes, it is only necessary to the most up place and mark time, the right position marked time of regulation, all peaces marked time can be completed
Dress, and every one-level marks time and all can come into operation immediately after installation.
Preferably, mark time panel and side plate of marking time is yi word pattern structure.
In this utility model, unit of marking time can be fabricated structure, it is also possible to be integral structure.
In order to improve the reliability of unit of marking time, the most conveniently play the termination plug-hole effect of unit of marking time, single mark time
In unit, the panel and mark time and be provided with plate torr between side plate of marking time, this plate torr is fixed on described ladder by connector and/or structure glue
On plate.Thus, whole unit class of marking time is similar to the triangular prism that a side is hollowed out, it is ensured that the while of light-weighted, structural strength
More preferably.
In order to sliding, loosening situation occurs in the panel that prevents from marking time, described in mark time and have locating slot on panel lower surface, institute
The top stating side plate of marking time is positioned at the locating slot of panel of marking time；The lower end of described plate torr is domatic with what gangboard gradient was mated
Structure.
In order to improve the structural reliability of unit of marking time, described in mark time panel and mark time between side plate, mark time panel and plate
Between torr and mark time and be equipped with structure glue and/or cement mortar between side plate and plate torr and sit slurry.
Preferably, described gangboard thickness is 80mm-110mm, most preferably 90mm-100mm.
Preferably, the top of described gangboard is had for being fixedly linked by the cast-in-place half space of connector Yu top
Reserving installation hole, the bottom of gangboard has the reserved installation for being fixedly linked by the cast-in-place half space of connector Yu bottom
Hole.It is highly preferred that connector is joint bar.
It is provided with structure glue and/or cast-in-place concrete between top and the cast-in-place half space on top of described gangboard, described
It is provided with structure glue and/or cast-in-place concrete between bottom and the cast-in-place half space of bottom of gangboard.
Lifting gangboard for convenience, the side of described gangboard is provided with suspension centre.
Compared with prior art, the beneficial effects of the utility model are:
1. use prestressing force gangboard, significantly alleviate gangboard weight, it is possible to decrease hoisting cost, convenient installation；
2. step plate splits into yi word pattern and marks time panel and yi word pattern is marked time side plate, it is simple in batches, standardized production；
3. plate torr uses heavy in section design, as Force transmission parts, is arranged on each both sides marked time, also has termination plug-hole
Effect.
