Wholesale manufacturer of steel formwork rental: Analysis of design requirements for highway steel formwork

The design of steel formwork for highways needs to follow multiple requirements to ensure construction quality and safety. The following is a detailed analysis:
Design principles
Practicality: The template joints should be tight and not leak grout, ensuring that the shape, size, and position of the components are correct, the structure is simple, and the support and disassembly are convenient.
Safety: It needs to have sufficient load-bearing capacity, rigidity, and stability to reliably withstand the weight of poured concrete, lateral pressure, and construction loads.
Economy: Adapt measures to local conditions, use local materials, reduce one-time investment, increase turnover times, and reduce labor costs for dismantling while ensuring construction period and quality.
Load consideration
Permanent loads: including the self weight of formwork and its supports, the self weight of newly poured concrete, the self weight of steel bars, etc.
Variable loads: including loads from construction personnel and equipment, loads generated during concrete vibration, pressure from newly poured concrete on the side of the formwork, loads generated during pouring concrete, etc.
Materials and Construction
Material selection: The panel should be made of high-quality steel, such as Q345 high-strength low-alloy steel, to ensure strength and toughness; The connecting and supporting components should also comply with relevant standards.
Component design: The specifications and spacing of panel thickness, back ribs, trusses, and other components should be designed reasonably to ensure the overall stiffness and stability of the formwork.
Production and processing
Precision control: Template production must strictly control the dimensional accuracy. The width, length, assembly hole spacing, and hole position of the flat template must meet the design requirements. The angles and dimensions of the internal and external corner templates must also be accurate.
Quality inspection: After processing, a comprehensive inspection of the appearance quality, dimensional accuracy, and component connection firmness of the template should be carried out to ensure that the template quality meets the standards.
Installment and use
Installation requirements: The template installation should be flat and firm, with tight joints. Adjacent templates should be flat and tight, and the support system should be firm and reliable. The tension bolts should be tightened to ensure that the template does not deform or shift during the concrete pouring process.
Construction coordination: When pouring concrete, the pouring speed and slump should be reasonably controlled to avoid excessive impact on the formwork; When vibrating, the vibrator should be inserted vertically into the concrete and avoid colliding with the formwork.
Demolition and maintenance
Demolition timing: The formwork and its supporting system can only be dismantled after the concrete strength meets the design requirements.
Maintenance: Regularly clean, remove rust, apply oil and other maintenance work on the template, promptly repair deformed and damaged parts, and ensure the service life of the template
