The step of pouring the reinforced concrete stairs is that various templates are erected according to the designed size, then concrete is poured on the erected templates, and after the concrete is solidified, the templates are disassembled to obtain the required stairs. The construction method commonly used for erecting the stair well template at present comprises the following steps: wooden templates and staircase templates are spliced and installed by a large number of iron nails. The method has the advantages of long template manufacturing period, complex template installation procedures, fragmented construction and long construction period; the consumption is large in the processing process, the reuse rate is low, the turnover frequency is low, and the like.

The common construction method for erecting the stair well formwork further comprises the following steps: the stereotyped template comprises a stereotyped steel template and a stereotyped aluminum template. The adoption of the shaped steel template has the defects of large template self weight and long time for occupying mechanical equipment; the prefabrication processing is required according to the actual engineering requirements, so the cost investment is high; the stair construction needs staggered floor construction, and can not be synchronously poured with shear walls on the same floor. The formed aluminum template has the problems that the deepened design is needed in the early construction stage, the structure and the size of the detail node of the building drawing need to be precisely calculated, the cost investment is high and the like.

In conclusion, how to realize the rapid installation and rapid removal of the stair well formwork and ensure the synchronous construction of the same-layer shear wall and the stair concrete becomes a problem to be solved urgently.

Compared with the prior art, the utility model also has the following beneficial effects:

1. the shear wall template, the inner side template, the outer side template, the bottom template and the plurality of step templates can be quickly assembled into a whole to form a stereotyped template and a tooled template, synchronous and quick assembly of the shear wall template and the stair template on the same layer can be realized, and the integrity of a concrete structure is ensured;

2. the forming effect of the stair concrete can be ensured;

3. the stair template is convenient to install and dismantle and simple to operate, and the building difficulty and the erecting time of the stair template are greatly reduced;

4. this stair template adopts wooden structure, and is not fragile, can used repeatedly, can effectual material saving cost and cost of labor.

5. The contact surfaces of the first tenon, the second tenon, the mortise and the tooth socket are covered with PVC protective moulds, so that the wear-resisting effect can be achieved, and repeated use can be realized; the PVC protective die has smooth surface, can realize socket connection between the rapid templates and ensure the accurate positioning of the stepping template; the damage of repeated mortise and tenon joints to the stair template is reduced, and the turnover frequency of the stair template is increased.
