Description

Technical Field

[0001] The present invention relates to an adjustable general staircase mold, belonging to the technical field of construction molds. Background Art

[0002] In traditional staircase construction, generally, formwork is supported on-site, followed by steel bar binding and concrete pouring. It takes more than ten days of continuous watering for curing to make the concrete strength reach the design strength. Then, the staircase surface is chiseled manually to make it rough, and then other decorative materials such as tiles or stones are pasted. The whole process is laborious and time-consuming, with serious pollution of sewage, dust, and noise, and a large amount of garbage is generated. For existing prefabricated staircase molds, usually, the building structure diagram is designed according to the size of the staircase bay first, and then the building structure diagram is split. During the splitting process, designers cannot well coordinate the resources of relevant industrial chains, resulting in personalized staircases after splitting. Therefore, there are various types of prefabricated staircases, with high manufacturing difficulty, high cost, low standardization degree of prefabricated staircases, which leads to heavy workload for designers, low reuse rate of prefabricated staircase molds, many on-site construction problems, extension of the cycle, and increase in cost, greatly reducing the benefits that the prefabricated construction method should bring.
