Prefabricated House Staircase Design

The design of staircases in prefabricated houses can utilize a multi-functional platform for scissor-type staircases in prefabricated buildings to address related issues. Details are as follows:

Functional Requirements

• Meeting Safe Formwork Needs: The platform can meet the safe formwork requirements for walls, columns, and prefabricated scissor-stair steel support beams in staircases. During the construction of staircases in prefabricated houses, formwork for walls, columns, and prefabricated scissor-stair steel support beams is a critical step. This platform provides stable support, ensuring that formwork operations can be carried out safely and smoothly, thereby guaranteeing the construction quality and safety of the entire staircase structure.
• Providing Edge Protection: Before the installation of prefabricated scissor stairs, the staircase is in a state of being adjacent to openings, posing significant safety risks. The platform can meet the requirements for edge protection on the working level, providing a safe working environment for construction personnel and effectively preventing accidents such as falls.
• Providing Safe Access: It offers a safe passage for workers to move up and down between different working levels through the staircase. During construction, workers need to move frequently between different working levels. This platform solves the problem of the lack of access in staircases, facilitating worker movement and improving construction efficiency.
• Easy Hoisting and Removal: The platform is easy to hoist and remove, and does not require secondary setup. This significantly saves construction time and labor costs, enhancing the flexibility and convenience of construction, and better adapting to the rapid construction needs of prefabricated houses.

Technical Design Features

• Using Stair Steel Support Beams for Load-Bearing: Consider using stair steel support beams for direct load-bearing, transmitting the platform's force directly to the stair steel support beams through eight adjustable crossbars. This design reduces the overall height of the platform, enhancing the safety of construction personnel working on the platform. Additionally, the eight adjustable crossbars are equipped with locking devices to prevent movement, further improving the safety of the platform during hoisting, use, and removal.
• Rational Installation Process: The installation process is clear and rational. First, hoist the platform into the scissor-type staircase of the prefabricated building; then remove the pins, adjust the eight adjustable crossbars to the steel support beams, and insert the pins for fixation; next, set up formwork for the staircase walls, columns, and stair steel support beams on the two-level working platforms, pour concrete, and then dismantle the staircase formwork; then hoist the platform to suspend it within the working level of the staircase, retract the adjustable crossbars, insert the pins for fixation, and remove the platform; finally, hoist the prefabricated stairs into the scissor-type staircase of the prefabricated building, and the above steps can be repeated.
