Technical Overview

This document provides detailed installation instructions and specifications for steel door sub-frames designed for both rigid and flexible walls, compliant with UNE-EN 1634-1:2010 fire resistance standards.

Main Sections and Summaries

1. Components and Materials

• Rigid Wall Installation: High-density rigid wall, galvanized steel sub-frame and CS5 frame, graphite intumescent seal, steel anchors, and self-tapping screws (Ø 6.3x60 mm DIN 7504P AUT.).
• Flexible Wall Installation (Plasterboard): Plasterboard panels (15 mm thick), rock wool insulation (23 mm), galvanized steel sub-frame and CS5 frame, U-shaped profiles and vertical transoms, various self-tapping screws (Ø 3.9x25 mm, Ø 3.9x45 mm, Ø 4.2x13 mm), graphite intumescent joint for fire prevention.

2. Installation Procedures

• Rigid Wall: Smooth the wall surface, fill with mortar, install the steel sub-frame anchored to the wall, then fix the CS5 frame to the sub-frame using self-tapping screws. The door leaf is introduced into the sub-frame, leveled horizontally and vertically, and secured. Expanding joints are removed and reinstalled after drilling for frame attachment. Door handles and closers are installed last. For double leaf doors, a bottom rod bush must be installed on the floor to prevent warping.
• Flexible Wall (Plasterboard): Assemble the sub-frame with U-shaped lengtheners and profiles, fix to ceiling and floor with anchoring squares and recommended screws (Ø 4.8x32 mm DIN 7981). Insert rock wool insulation between profiles and transoms. Attach plasterboard liners on both sides with self-tapping screws. Seal joints with gunning paste and cover screw holes. Leveling is critical throughout installation.

3. Dimensional and Clearance Specifications

• Slack tolerances between door leaf and frame or floor are specified for Turia-Delta and DH Turia models, generally ranging from 3 mm to 7 mm with ±3 mm tolerance.
• U-shaped profiles must be installed with a 30 mm slack on each side to fit the lintel properly.

4. Fire Safety and Standards Compliance

• The door systems are adapted to UNE-EN 1634-1:2010, ensuring fire resistance.
• Graphite intumescent seals and joints are used to enhance fire prevention.

5. Advantages and Best Practices

• The door is installed last to avoid damage and maintain brick-to-brick dimensions.
• The door stands on an independent steel structure, improving stability.
• Use of appropriate screws and anchors is emphasized for secure fixing.
• Leveling both vertically and horizontally is critical for proper function.
• Installation instructions must be followed closely to maintain specified clearances and performance.

6. Finishes

• Available finishes include white, galvanized, antifingerprint, and stainless steel options for the door and frame components.

Summary of Critical Parameters

• Screws: Various sizes specified for different parts (Ø 6.3x60 mm, Ø 4.2x13 mm, Ø 3.9x25 mm, Ø 3.9x45 mm).
• Profiles: U-shaped profiles 48 mm wide, plasterboard thickness 15 mm, rock wool insulation 23 mm thick.
• Clearances: Leaf-to-frame and leaf-to-floor clearances between 3 mm and 7 mm with ±3 mm tolerance.
• Anchoring: Use of steel anchors and anchoring squares fixed to ceiling and floor.

Conclusion

This document provides comprehensive technical guidance for installing fire-resistant steel door sub-frames in both rigid and flexible wall constructions. It emphasizes precise measurements, proper use of materials, and adherence to fire safety standards to ensure durability, safety, and functionality of the door systems.
