The steel frame structure platform uses the method of selecting Bailey panels produced by the manufacturer.

The execution of the template support method with a larger margin of safety is more reliable, saving both the construction period and the costs of high support template setup and bottom floor structure reinforcement. The steel frame structure platform uses Bailey plates produced by the manufacturer, which do not need processing; they can be rented from the market, allowing for better price control.

During the roof construction in Area A, the construction tower crane lifts a single Bailey frame to the floor, where it is assembled on-site with the long side of the floor opening for the entire span module template support. Then, the hydraulic machine moves the entire single unit to the required construction line. In Area B, with a smaller span, the construction tower crane assembles the entire span on the ground and moves it to the required position, forming a complete platform after laying out the edges.

As a platform for the template support system, the Bailey frame is lighter and more modular compared to traditional scattered steel frame conversion layers, making it easier to install and providing a higher capital turnover rate.

Structural characteristics of the Bailey frame conversion platform

The Bailey frame conversion platform simplifies the construction of high support templates, reducing the complexity of setting up high support templates to a height of one layer, thereby lowering safety risks.

The steel frame structure platform uses Bailey plates produced by the manufacturer. Due to the truss structure, it has high bending strength, tensile strength, and bending stiffness on the plane, which can meet the requirements for various compressive strength and deformation indicators without setting support components or tension rods in wider edge conditions.

The Bailey frame conversion platform mainly considers the stability and arrangement of the plane, adding horizontal tie rods and braces between every two modules to create a unit prefabricated component. Each module is calculated based on the opening size, and the arrangement is done according to the building cross-section size, with the overall structure formed as a conversion platform through the installation of the bottom steel of the vertical columns on the surface of the Bailey frame platform.

Combining the edge span dimensions, the Bailey plates produced by the manufacturer are effectively combined into modules of 1.5m×3.0m, placed at the floor opening, and pads are left at the bottom of the conversion platform's load-bearing beams, creating a force transmission system from the Bailey frame platform to the floor load-bearing beams and then to the columns. The floor load-bearing beams are checked, and if they do not meet the load-bearing requirements, reinforcement is needed by increasing the beam cross-section size and stirrups or by maintaining the support structure at the bottom of the beams.

The production process of the high support template Bailey frame conversion platform: Based on the beam and slab load stress analysis, determine the spacing of the Bailey frames on the floor → Select the assembly method of the Bailey frame according to the lifting standards → After assembling a single Bailey frame on the floor or ground, assemble the module components → Create module prefabricated components at the edge of the floor opening for lifting or choose to push into place → Install and adjust the bottom steel of the upper support of the Bailey frame → Set up fixed supports and template management systems → After pouring concrete, wait until the stripping strength is reached to dismantle the Bailey frame.
