Hidden Structural Review Drawing & Back-Bolt Dry Hanging Method for Black Travertine Marble

1. Hidden Structural Review Drawing

A hidden structural review drawing is an essential part of the black travertine marble layout drawing, corresponding one-to-one with the dry-hanging stone layout. This means that if a dry-hanging stone layout drawing exists, there must also be a corresponding dry-hanging steel structure drawing for review.

Key Inclusions in the Structural Drawing:

• Detailed layout of channel steel and angle iron.
• Arrangement of embedded steel-reinforced plates.
• Guidance for future maintenance and refurbishment.
• A dedicated copy of the hidden structure application drawing.
• Vertical section, cross-section, and embedded parts of the stone dry-hanging system.
• Anti-rust treatment methods for all auxiliary materials (especially solder joints).

2. Back-Bolt Method for Dry Hanging Black Travertine Marble

2.1. Overview

The back-bolt connection is a curtain wall fixing method that connects black travertine marble to the structural framework using double-section seismic back-cut anchor bolts and connectors.

2.2. Advantages of the Back-Bolt Method

1️⃣ Independent Load Bearing – Each stone panel is independently installed and replaced, allowing for flexible node configurations.
2️⃣ Reliable Connection – Reduces weakening of the stone, minimizes local damage, and enhances seismic capacity.
3️⃣ Flat Surface Guarantee – The distance between the stone and the bottom of the conical hole is precisely controlled, ensuring a smooth curtain wall surface.

2.3. Disadvantages of the Back-Bolt Method

1️⃣ Stone Thickness Requirement – The stone must be at least 25mm thick, with 30mm recommended.
2️⃣ Large Installation Space Required – The distance between the stone surface and the base layer is 250-300mm, which may not be practical for limited spaces.
3️⃣ Batch Processing Requirement – Back bolt holes must be processed using specialized equipment, requiring batch production (each board requires four back bolt holes).
4️⃣ Stone Size Limitation – The stone panels should not exceed 1.5 square meters, and pendants are typically made of stainless steel.

3. Back-Bolt Installation Process

• Drilling – Using specialized drilling equipment, precise “large inside, small outside” conical holes are created on the back of the marble.
• Anchor Bolt Insertion – The anchor bolt is inserted into the hole.
• Screw Tightening – The screw is tightened, causing the bottom of the anchor bolt to expand fully.
• Stress-Free Convex Joint Formation – The anchor bolt and conical hole fit together perfectly, forming a secure, stress-free convex joint.
• Final Fixing – The porcelain plate is securely attached to the keel using connecting pieces.
