6 tipi di staffe nei sistemi di sospensione a secco in pietra spiegati

Stone dry hanging is a widely adopted technique in modern architectural cladding, known for its safety, efficiency, and aesthetics. Central to this method are various types of stone dry hanging brackets (also known as stone cladding fixings or hangers). These components provide crucial structural support and secure stone panels on buildings.

This article explores the types of dry hanging brackets used in stone applications, comparing their advantages, disadvantages, and optimal use cases. Whether you’re an architect, contractor, or stone enthusiast, this guide will help you choose the right hardware for your stone installation projects

What is Stone Dry Hanging?

Stone dry hanging is a method of installing stone slabs or panels onto walls or facades without the use of traditional cement mortar. Instead, mechanical brackets and fixings support the stone, offering numerous advantages:

• Reduced construction time
• Improved safety and earthquake resistance
• Easy maintenance and future replacements
• Better ventilation and insulation

Types of Stone Dry Hanging Brackets

1. Double Hook Brackets (Double-Groove Brackets)

Caratteristiche:

• These brackets provide both upper and lower connections to the stone.
• Commonly used due to their balance of safety and efficiency.

Advantages:

• Shorter installation time compared to back bolts.
• Good structural strength.

Disadvantages:

• Difficult to disassemble or replace individual panels after installation.

Use Case: Ideal for large-scale exterior wall cladding where long-term stability is crucial.

2. T-Shape Welding Brackets (T-Shape Welded Anchors)

Caratteristiche:

• Thin base plates that offer better support for thinner stone panels.

Advantages & Disadvantages:

• Shares similar pros and cons with double hook brackets.
• Better suited for delicate or thin stones due to reduced pressure points.

Use Case: Used when working with thin slabs or when aesthetic edges are critical.

3. Tilted Brackets (Stone Tilt Brackets)

Caratteristiche:

• Provide two additional fixed points, turning a two-point hold into a four-point system.

Advantages:

• Improved load-bearing capacity.
• Adds stability, especially at the top and bottom layers of the structure.

Use Case: Common at the base or top of buildings where additional support is required.

4. Corner Brackets (Angle Brackets)

Caratteristiche:

• Eliminates the need for an entire supporting keel.

Advantages:

• Saves space and reduces cost.
• Simplifies installation.

Disadvantages:

• Less secure than using a full frame.

Use Case: Best for interior wall installations or small-scale projects like decorative backgrounds.

5. Angle Brackets and Angle Welded Brackets

Caratteristiche:

• Simple L-shaped brackets used in projects with flat wall surfaces.

Advantages:

• Further reduces material usage.

Disadvantages:

• Wall surface must be very flat.

Use Case: Interior projects or renovations with minimal structural demands.

6. Straight Plates (Single-Hole and Double-Hole Plates)

Caratteristiche:

• Auxiliary components used to extend or level brackets.

Use Case:

• Extend reach if brackets are too short.
• Adjust for uneven walls during installation.

How to Choose the Right Stone Hanging Bracket

When selecting the appropriate bracket for your stone cladding project, consider the following factors:

1. Stone Thickness and Weight: Thinner stones benefit from T-shaped welded anchors.
2. Project Scale: Use double-hook or tilt brackets for large exteriors.
3. Wall Flatness: Angle brackets are only suitable for flat wall conditions.
4. Budget and Time Constraints: Corner brackets help reduce cost and labor.
5. Maintenance Needs: For easy replacements, avoid brackets that are hard to dismantle.

Installation Tips for Stone Hanging Brackets

• Always check wall load-bearing capacity before installation.
• Use stainless steel or anti-corrosion materials for durability.
• Regularly inspect installed brackets for rust or structural damage.
• Maintain at least 4-point support for heavy or large stone panels.

FAQs About Stone Dry Hanging Brackets

1. What are stone dry hanging brackets used for?

Stone dry hanging brackets are used to mechanically fix stone panels to walls or facades without mortar. They provide structural support and ensure safety and aesthetic appeal.

2. Which is better: double-hook brackets or back bolts?

Double-hook brackets are faster to install and widely used, while back bolts are more secure but labor-intensive. The choice depends on the project’s safety and aesthetic requirements.

3. Are T-shape welded brackets suitable for all stones?

No. T-shape welded brackets are ideal for thin stones that require delicate handling, offering better edge protection.

4. Can I use corner brackets for outdoor cladding?

It’s not recommended for large or outdoor projects due to lower structural reliability. Corner brackets are best for small interior installations.

5. Do stone dry hanging systems require a metal frame?

Not always. Systems like corner brackets or angle welded brackets may work without a full keel, but structural safety must always be evaluated.
