The design principles of handmade silicate sandwich panels involve many aspects, aiming to ensure its structural stability, thermal insulation performance, fire safety and construction convenience.
1. Structural stability design
Core material selection: Select high-strength and lightweight core materials as the sandwich layer, such as inorganic materials such as silicates. These materials have good compressive strength and bending stiffness, and can effectively support the panel and withstand external loads.
Panel design: The panel material should be selected from materials with good durability and corrosion resistance, such as galvanized steel or aluminum. The thickness and strength of the panel should be designed according to the use environment and force requirements of the sandwich panel to ensure the stability of the overall structure.
Connection design: The connection between the panel and the core material should adopt a reliable connection method, such as adhesive bonding or mechanical fixing. The connection points should be evenly distributed to ensure that the sandwich panel can evenly transfer the load when it is stressed, and avoid local stress concentration and damage.
2. Thermal insulation performance design
Core material thermal conductivity: Select a core material with low thermal conductivity as the sandwich layer to improve the thermal insulation performance of the sandwich panel. Inorganic materials such as silicates usually have low thermal conductivity and are suitable for use in the field of thermal insulation.
Thickness optimization: According to the use environment and thermal insulation requirements, the thickness of the sandwich panel should be reasonably designed. Increasing the thickness of the sandwich layer can improve the thermal insulation effect, but it will also increase the cost and weight, so comprehensive consideration and optimization design are required.
Edge sealing: Strengthen the sealing treatment of the edges of the sandwich panel to prevent air infiltration and heat exchange, and improve the thermal insulation performance.
3. Fire safety design
Material fire rating: Select materials that meet fire safety requirements, such as Class A non-combustible materials as sandwich panels and panel materials. These materials are not easy to burn in a fire and can effectively prevent the spread of fire.
Fireproof structure design: Consider fire protection requirements in the structural design of the sandwich panel, such as setting up fire isolation belts and using fire-resistant components. These measures can improve the overall fire resistance of the sandwich panel and ensure a certain fire resistance time in a fire.
Fireproof coatings and sealants: Apply fireproof coatings on the surface of the sandwich panel to increase the fire resistance limit of the material. At the same time, fireproof sealant is used to seal the joints to prevent the fire from spreading through the gaps.
4. Design for ease of construction
Standardized size: Design standardized sandwich panel sizes and specifications to facilitate installation and splicing during construction. Standardized size can reduce on-site processing and improve construction efficiency and quality.
Lightweight design: Reduce the weight of the sandwich panel as much as possible while ensuring structural strength and thermal insulation performance. Lightweight design can reduce construction difficulty and cost and improve construction efficiency.
Easy-to-install connectors: Design connectors and fasteners that are easy to install and disassemble, such as self-tapping screws, snaps, etc. These connectors should have good fastening performance and durability to ensure that the sandwich panels can be firmly connected and remain stable during installation.
The design principles of handmade silicate sandwich panels include structural stability, thermal insulation performance, fire safety, and ease of construction. By comprehensively considering these design principles and optimizing the design, it can be ensured that the sandwich panels have good performance and stability during use.
