technical field

The utility model relates to the technical field of staircase molds, in particular to a vertical adjustable prefabricated staircase mold.

Background technique

With the continuous introduction of relevant national policies, the prefabricated building system is developing rapidly across the country like mushrooms after rain. The prefabricated building means that the corresponding building prefabricated components are produced in the processing factory, and then the prefabricated components are transported to the construction site for assembly. Through this system, the purpose of short construction period, low cost and high efficiency can be achieved. In the building prefabricated component factory, the pros and cons of the stair mold determine the dimensional accuracy, visual quality, production cycle and other issues of the prefabricated staircase. Therefore, how to make the prefabricated staircase mold easy to operate, low cost, high efficiency and high quality characteristics are particularly important.

Defects and insufficiencies of existing technologies: Although my country's construction industrialization has huge market potential, due to the weak working foundation, it must be admitted that the overall development situation is still relatively severe, mainly facing the following challenges:

1. The existing steel stair molds need to be customized according to the requirements of the drawings. Due to the different specifications of the stairs, the versatility is poor, and the low utilization rate leads to waste of materials and increased costs.

2. The existing steel staircase molds need to be processed according to different staircase specifications and sizes. The number of mold specifications is large, occupying space and affecting the construction period.

3. Wooden prefabricated staircase molds can be recycled for a small number of times and the quality is difficult to guarantee.

4. The on-site pouring method is adopted, which requires a large amount of on-site work, serious dust and noise pollution, and is greatly affected by the natural environment, so it is difficult to guarantee a long construction period.

5. The on-site pouring method is adopted. Due to the limitation of the on-site operation environment, the appearance quality is not beautiful enough, and the engineering installation accuracy is not high.

6. Adopting the method of on-site pouring, the formwork system has a large workload, a long construction period and many safety hazards.

7. The existing prefabricated staircase mold consumes a lot of manpower and material resources in the assembly process, which does not conform to the principle of green building.
