Problems solved by technology

At present, there are many changes in the modulus of the stairs. For example, due to the change of the floor height, the stair step height needs to be changed within 150-200mm. It can be seen that the change range is large.
The use of precast concrete staircase molding equipment in the prior art has three prominent disadvantages: (1) the fixed modulus is used, the scope of application is small, and flexible production cannot be realized; (2) the mold customization cycle is long, and the unit cost is high. The amortization of molds in the cost of stairs is large; (3) Usually a batch of molds are customized for a project, and the molds are scrapped after the project is completed, which is a big waste and fails to achieve energy conservation and environmental protection

Abstract

The invention relates to a vertical adjustable modulus prefabricated staircase forming equipment and a step height adjustment method thereof. The vertical adjustable modulus prefabricated staircase forming equipment includes a fixed side form, a movable side form and a stair step module, and also includes a guide device, Drive control module, chute synchronizer, detection control module, bottom mold lifting module, quick mold opening and closing device, mechanical locking device, quick disassembly module; a vertical adjustable modulus prefabricated staircase forming equipment adopting this scheme With the stepless adjustable modulus of the stair mold step height, stair width, and stair steps, one piece of equipment can meet the production requirements of various types of stairs, realize the flexible and automatic production of prefabricated components, and greatly improve production efficiency at the same time It also has the advantage of greatly reducing the production cost of prefabricated stairs.

Description

technical field [0001] The invention relates to a vertical adjustable modulus prefabricated staircase forming equipment and a step height adjustment method thereof Background technique [0002] Prefabricated buildings are developing rapidly at this stage, especially the demand for concrete prefabricated stairs is growing rapidly. Most of the traditional prefabricated staircase production equipment adopts the fixed mold form. The stair tread height, stair width, and stair step cannot be adjusted. A stair with a specification must be customized to correspond to the corresponding mold; some can only be used in a small range. Adjust the height of the stair treads. At present, the modulus of stairs changes a lot. For example, due to the change of floor height, the stair step height needs to change within 150-200mm, which shows that the range of change is relatively large. The use of precast concrete staircase molding equipment in the prior art has three prominent disadvantages:...
