Steel structure equipment frame

Steel structure equipment frame is a structural form widely used in industry, construction, and infrastructure, mainly composed of steel. Due to its advantages of high strength, lightweight, and fast construction, it is widely used in multiple fields. Attention should be paid to load, material selection, stability, and node design during design and construction, and regular maintenance should be carried out to extend the service life.

Components

Steel structure frames typically consist of the following parts:

Steel Columns: Vertical supporting structures that bear upper loads and transfer them to the foundation.

Steel Beams: Horizontal members that connect steel columns and support floors, roofs, etc.

Bracing Systems: Including horizontal and vertical bracing to enhance structural stability and resistance to lateral forces.

Connectors: Such as bolts, welding, etc., used to connect various components.

Foundation: Usually a concrete foundation used to fix steel columns and transfer loads to the ground.

2. Common Specifications

The specifications of steel structure equipment frames are determined based on specific design requirements and load conditions. Below are some common specification ranges:

(1) Section Steel Specifications

H-Beam:

Common specifications: H100×100 to H400×400 (height × width, unit: mm).

Characteristics: Rational cross-sectional shape with strong load-bearing capacity, suitable for main beams, columns, and other primary load-bearing components.

I-Beam:

Common specifications: I10 to I63 (height, unit: cm).

Characteristics: Suitable for secondary beams, bracing, and other secondary load-bearing components.

Angle Steel:

Common specifications: L30×30×3 to L100×100×10 (side length × side length × thickness, unit: mm).

Characteristics: Used for bracing, connectors, etc.

Channel Steel:

Common specifications: [10 to [40 (height, unit: cm).

Characteristics: Suitable for secondary beams, bracing, etc.

(2) Steel Plate Specifications

Thickness: Typically 6mm to 50mm.

6mm to 12mm: Used for lightweight structures or non-primary load-bearing parts.

12mm to 25mm: Used for medium-load structures.

Above 25mm: Used for heavy-load structures.

Width and Length: Customized based on design requirements, common widths are 1.5m to 3m, and lengths are 6m to 12m.

(3) Steel Pipe Specifications

Round Pipe:

Common specifications: Φ50×3 to Φ300×12 (outer diameter × wall thickness, unit: mm).

Characteristics: Used for columns, bracing, etc.

Square Pipe:

Common specifications: □50×50×3 to □200×200×10 (side length × side length × wall thickness, unit: mm).

Characteristics: Used for frame structures, bracing, etc.

(4) Connector Specifications

Bolts:

Common specifications: M12 to M24 (diameter, unit: mm).

Strength grades: 8.8, 10.9 (high-strength bolts).

Welding Materials:

Electrodes: E43 series (for Q235 steel), E50 series (for Q345 steel).

Welding wire: Selected based on the type of steel.

3. Material Selection Principles

Load Conditions: Select steel with appropriate strength based on equipment weight, wind load, seismic load, etc.

Usage Environment:

Ordinary environments: Carbon steel or low-alloy steel such as Q235 and Q345.

Corrosive environments: Weathering steel, stainless steel, or galvanized steel.

Cost-Effectiveness: Choose cost-effective materials while meeting performance requirements.

Processability: Consider weldability and machinability of materials.

4. Specification Design Principles

Safety: Ensure component dimensions and specifications can withstand design loads.

Stability: Ensure overall structural stability through rational cross-sectional design and bracing systems.

Cost-Effectiveness: Optimize material usage to reduce costs while meeting safety and stability requirements.

Standardization: Prefer standard specifications for section steel and plates to facilitate procurement and construction.

5. Anti-Corrosion and Fire Protection Treatments

Anti-Corrosion Treatment:

Apply anti-corrosion paint (e.g., epoxy zinc-rich primer, polyurethane topcoat).

Hot-dip galvanizing.

Fire Protection Treatment:

Apply fireproof coatings to improve fire resistance.

Select appropriate fire protection measures based on fire resistance rating requirements.

Advantages

High Strength: Steel's high strength makes it suitable for large spans and heavy-duty equipment.

Lightweight: Compared to concrete, steel is lighter, facilitating transportation and installation.

Rapid Construction: Prefabricated components can be processed in factories, enabling quick on-site assembly.

Reusability: Steel is recyclable, aligning with environmental sustainability.

Excellent Seismic Performance: Steel's toughness provides superior earthquake resistance.
