龙骨支架

龙骨支架 (Lónggǔ zhījià), commonly translated as keel support or stud framing, refers to a structural component used to provide support for various constructions, primarily in building and display systems. The term encompasses a range of implementations based on material and specific application.

Material

• Metal: Steel is the most common material, offering high strength and durability. Aluminum is used in lighter-duty applications, particularly for displays and temporary structures.
• Wood: Historically, wood was the primary material for dragon bone supports. It remains in use for certain construction types and decorative applications.
• Plastic: PVC and other plastics are used for lightweight, corrosion-resistant supports, often in indoor display and signage.

Purpose

The primary purpose of dragon bone supports is to create a stable framework. This framework then supports:

• Building Construction: Forms the skeletal structure of walls, roofs, and floors. Provides attachment points for cladding, insulation, and finishing materials.
• Display Systems: Supports backdrops, banners, signage, and exhibits in trade shows, retail spaces, and events.
• Greenhouses & Agricultural Structures: Provides the foundational support for plastic sheeting, shading, and plant supports.
• Temporary Structures: Used in staging, event setups, and temporary shelters.

Function

• Load Bearing: Distributes weight evenly to the foundation or supporting structure.
• Structural Stability: Resists bending, shear, and compressive forces.
• Attachment Points: Provides surfaces for securing other components using fasteners, welding, or adhesives.
• Dimensional Accuracy: Maintains the desired shape and alignment of the structure.

Usage Scenarios

• Residential & Commercial Buildings: Steel or wood framing for walls, roofs, and floors.
• Trade Show Booths: Aluminum or steel supports for backdrops, lighting, and displays.
• Retail Displays: Metal or plastic supports for shelving, signage, and product presentation.
• Agricultural Greenhouses: Galvanized steel or PVC supports for plastic film and plant structures.
• Event Staging: Steel supports for lighting rigs, sound systems, and backdrops.
• Photographic and Videographic setups: Supports for backdrops and lighting.

Common Types

• Steel Studs: C-shaped steel profiles used for interior and exterior wall framing. Available in various gauges and depths.
• Steel Joists: I-shaped steel beams used for floor and roof support.
• Wood Studs: Rectangular lumber used for wall framing, typically 2x4 or 2x6 dimensions.
• Aluminum Extrusions: Custom-shaped aluminum profiles used for display systems and lightweight structures. Often modular and connectable.
• PVC Pipe Frames: Lightweight, corrosion-resistant frames constructed from PVC pipes and fittings, commonly used for banners and lightweight displays.
• Adjustable Display Stands: Modular stands with adjustable height and width, used for banners, posters, and signage. These often use aluminum or steel components.
• Truss Systems: Interconnected triangular frameworks made of steel or aluminum, used for supporting heavy loads such as lighting and sound equipment.
