Preferably, described partition wall top is provided with Cast-in-situ Beam, and this Cast-in-situ Beam forms integral structure with bracket beam.
As a kind of concrete version, in adjacent two-stage stepping unit, upper level is marked time, and to have lower limit domatic for the riser bottom of marking time of unit, and mark time prefabricated tread plate the inner of unit of next stage has and domatic with described lower limit coordinates spacing upper limit domatic；The lower end of described precast stair plate has marks time the limiting stand of unit for positioning subordinate.Thus, it is provided with limiting stand due to the bottom of gangboard, 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, can use after installation at once.
As a kind of concrete version, mark time in unit for every grade, having inside the upper surface of described prefabricated tread plate and dock recess for what the riser bottom of marking time of unit of marking time with upper level was fixed, the bottom of this riser of marking time is connected with the docking mating recesses of corresponding prefabricated tread plate.
Preferably, mark time the spacing domatic of riser of marking time of unit of subordinate is arranged on inside described limiting stand.Can certainly open translot on limiting stand, the riser part of marking time of unit of then subordinate being marked time realizes spacing in snapping in translot, the most this structure is the most more complex.The prefabricated tread plate of every grade of unit of marking time and marking time is fixedly linked by left plate and the right plate arranged between riser.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 is more preferable.
Preferably, described left plate and right plate respectively and are fixedly linked by connector between gangboard.
As a kind of concrete connected mode, described gangboard having multiple gangboard installing hole, the bottom face of described left plate and right plate has hole, location, in described connector is placed in corresponding gangboard installing hole and hole, location, unit of marking time is fixed on gangboard.The most described connector is connecting pin.
In order to ensure that connector will mark time unit and gangboard is firmly coupled to each other, in described installing hole and hole, location, it is provided with mortar seat slurry or structure glue.
In order to reduce processing step, improve the structural strength of unit of marking time, every grade of integrated molding structure of unit of marking time.Cellular construction comparison rule of marking time of the present utility model, integrated molding provides possibility.
Compared with prior art, the beneficial effects of the utility model are: the single construction weight of this utility model is light, can use small dimension tower crane, save installation cost, and die cost is low, and versatility is higher, and production cost is low.

Detailed description of the invention
A kind of prefabricated staircase structure, such as Fig. 1 and 2, shown in 3, is mainly made up of cast-in-place bracket beam 4, prefabricated partition wall 1, precast stair plate 5, prefabricated tread plate and prefabricated riser.Prefabricated partition wall 1, precast stair plate 5, prefabricated tread plate, prefabricated riser is made respectively during production.Prefabricated partition wall of the present utility model as general prefabricated partition wall, prefabricated by prefabrication, first hoisting prefabricated partition wall when stair are installed, on prefabricated partition wall, then squeeze into bar planting 6, reproduce and water bracket beam.Gangboard is ridden over (precast stair plate 5 uses minor face to overlap) on cast-in-place bracket beam 4 after pouring installation by bracket beam again, and prefabricated tread plate, prefabricated riser are combined into an entirety.
Owing to prefabricated partition wall, precast stair plate, prefabricated tread plate, prefabricated riser make respectively in factory, volume is little compared with integral prefabricated stair, it is simple to transport, can transport in batch, save cost of transportation, further, since stair use minor face overlap joint, so gangboard thickness is set to 80mm, greatly reduce the weight of stair, so the crane gear that can use more small dimension is installed, save equipment installation cost, easily facilitated in-site installation.
At factory respectively prefabricated partition wall, precast stair plate, first lifting partition wall sets up support, cast-in-place bracket beam 4, and sets up lifting staircase boards and be installed to tram, and the most manually installed prefabricated tread plate, tread plate are to tram.Prefabricated partition wall, precast stair plate, prefabricated tread plate, prefabricated riser are combined into an entirety.As it is shown in figure 1, precast stair plate is shelved on cast-in-place rearmounted beam, then pedal is arranged on gangboard with gangboard combination.As shown in Figures 2 and 3, on partition wall after bar planting, pour installation bracket beam.
The content that above-described embodiment illustrates should be understood to that these embodiments are only used for being illustrated more clearly that this utility model, rather than limit scope of the present utility model, after having read this utility model, those skilled in the art each fall within the application claims limited range to the amendment of the various equivalent form of values of the present utility model.
