The design principles for vertical suspension of fiberglass must comprehensively consider acoustic performance, spatial aesthetics, structural safety, and maintenance convenience. The specific principles are as follows:
1. Principle of acoustic performance optimization
Uniform distribution and directional absorption
Glass fiber hangings should be evenly distributed at the top of the space or in specific sound source areas to ensure uniform absorption of sound waves. For example, in a conference room, the spacing between hangings can be designed to be 200-300mm, forming a continuous acoustic barrier to reduce echo interference.
Frequency response matching
Select fiberglass materials with different densities based on spatial functions. For example, for a concert hall, which requires low-frequency absorption, fiberglass boards with a thickness of ≥50mm can be chosen; for offices, which primarily focus on mid-to-high frequency absorption, a thickness of 20-30mm is sufficient.
Combination of diffusion and absorption
Acoustic wave diffusion is achieved through surface treatment of the vertical fins (such as punching and slotting), avoiding excessive absorption that leads to "dead silence" in the space. For example, fiberglass vertical fins with a porosity of 10%-15% can achieve both sound absorption and diffusion.
II. Principles of spatial aesthetic design
Form and proportion
The shape of the vertical fins should match the spatial scale. For example, in a space with a height of 3-5 meters, the length of the vertical fins should be 1.5-3 meters and the width should be 0.3-0.6 meters, creating a visual rhythm.
Color and material
Use low-saturation colors (such as gray, white, and beige) to reduce visual interference, or achieve a gradient effect through surface coating. For example, Lome fiberglass vertical panels can be customized to any color from the RAL color chart.
Combination of dynamic and static
Incorporating lighting design, light and shadow variations are created through translucent fiberglass vertical panels. For instance, an LED strip can be installed behind the vertical panels to produce a starry sky effect at night.
III. Principle of structural safety
Load calculation
Additional loads such as the self-weight of the vertical fins, wind loads, and personnel contact need to be considered. For example, when the weight of a single vertical fin is ≤15kg, light steel joist suspension can be used; when the weight is >15kg, a steel structure conversion layer needs to be added.
Connection node design
The connection between the vertical piece and the keel should be flexible to avoid stress concentration. For example, rubber gaskets or spring clamps can be used to allow the vertical piece to swing freely within a range of ±5mm.
Fire resistance and durability
The fiberglass material must meet Class A fire protection standards, and its surface coating should be resistant to ultraviolet aging. For instance, the back of the hanging piece can be laminated with a 0.5mm thick aluminum plate to enhance fire resistance.
IV. Maintaining the principle of convenience
modular design
The vertical panels should adopt standardized dimensions (such as 600mm×1200mm) to facilitate quick replacement. For example, a gymnasium project adopts a snap-on connection, with a single panel replacement time of ≤5 minutes.
Cleaning and maintenance access
The spacing between vertical fins should be ≥100mm, with reserved maintenance space. For example, removable vertical fins can be installed above the air conditioning return air inlet to facilitate equipment maintenance.
Identification and archive management
Each hanging piece should be labeled with a number and the date of installation, and an electronic archive should be established. For example, QR codes can be used to record material parameters, construction information, and maintenance records.
V. Innovative Application Cases
Dynamic acoustic device
A certain art gallery adopts motor-driven vertical plate swinging to adjust the acoustic environment according to the flow of people. For example, the vertical plate swinging frequency is 0.5-2Hz, and the sound field reverberation time can be adjusted in real time.
Photovoltaic integrated design
Integrate flexible photovoltaic panels on the surface of the vertical fins, achieving a power generation efficiency of ≥15%. For example, a commercial complex project generates 5000kWh of electricity annually, meeting part of its lighting needs.
Biomimetic structure
By mimicking the morphology of plant fibers, a vertical ecological wall is woven using fiberglass. For instance, the spacing between vertical strips can be adjusted to accommodate plant growth, creating a "breathing" building skin.
Summary of design principles: The vertical suspension of fiberglass requires a balance between acoustic performance, spatial aesthetics, structural safety, and maintenance convenience. Through modular design, dynamic adjustment, and multidisciplinary integration, the unity of function and form can be achieved, meeting the comprehensive needs of modern architecture for acoustics, visual aesthetics, and sustainability.
