Embodiment 2
[0050] refer to Figure 6 , The difference between the second embodiment and the first embodiment is that the driving member is different, and the driving member is a compression spring 10 . The lower end of the support beam 1 is fixedly connected to one end of the compression spring 10 , and the other end of the compression spring 10 is fixedly connected to the bottom wall of the second placement groove 42 . The upper end of the support beam 1 is provided with a positioning groove 12, and the positioning groove 12 is inserted with a positioning rod 20. When the positioning rod 20 is pulled out, the compression spring 10 drives the support beam 1 to slide upwards, so that the contact area between the support beam 1 and the lateral step block 21 changes.
[0051] refer to Figure 6 , the upper end of the support beam 1 is distributed with three positioning grooves 12 , and the positioning grooves 12 are distributed along the length direction of the support beam 1 . When the ...

The invention discloses a fabricated stair, and relates to the technical field of stairs. The problem that the construction period of the stair is long is solved. The fabricated stair comprises a supporting beam, and the two ends of the supporting beam are erected between conversion platforms of adjacent floors correspondingly; the fabricated stair further comprises a plurality of sets of treading assemblies; each treading assembly comprises a transverse treading block and a vertical treading block, wherein the lower end of the vertical treading block is fixedly connected with the side wall of the transverse treading block, a penetrating hole is formed in the outer wall of the side, back on to the vertical treading block, of the transverse treading block, and the vertical treading block and the transverse treading block which are adjacent to the supporting beam abut against each other; the two ends of the supporting beam are detachably connected with fixing pieces; and each conversion platform is provided with a first containing groove allowing the upper end of the supporting beam to slide in and a second containing groove allowing the lower end of the supporting beam to slide in, and a cover plate is mounted on each conversion platform. When the fabricated stair is mounted, the multiple sets of treading assemblies sequentially slide into the supporting beam, the stair can be formed, and therefore the assembling process of the stair is simple, and the mounting process of the stair on site can be shortened.
Description
technical field [0001] The present application relates to the technical field of stairs, in particular to an assembled staircase. Background technique [0002] Elevators are generally installed in current buildings, but stairs are still one of the important parts of building structures, and stairs are the main escape routes for high floors. Existing stairs are all formed by pouring on-site. When pouring stairs on-site, it is necessary to set up the stair pouring formwork first. [0003] The current stair pouring formwork, as described in the patent of the authorized announcement number CN205976492U, has a bottom formwork, two lateral formworks and a plurality of transverse baffles, and the two sides of the bottom formwork are respectively placed between the upper and lower adjacent floor conversion platforms. The side templates are respectively vertically fixed on both sides of the bottom template, and there are card slots on the side templates, and a plurality of horizonta...
