  • Officially approved combinations include HLB M-50/250 and HLB M-20/250 with HLB M-100/250.
Load Capacity and Design
The document provides detailed load capacity values according to Eurocode 2, with specific design values for transverse load capacities both parallel and perpendicular to the joint. It includes interaction diagrams and equations for calculating load capacities.
Construction and Load Bearing Behavior
  • Transfer of tension and shear loads is explained with models and diagrams.
  • Notes on fire protection and the behavior of steel wire loops under high temperatures are included.
Conclusion
The HALFEN HLB Loop Box offers a reliable and efficient solution for constructing junctions in precast concrete elements, with official approvals and detailed technical specifications ensuring compliance with industry standards.
Overview
The document provides detailed technical specifications and installation instructions for the HALFEN HLB Loop Box system, used in construction for reinforcement steel and tensioning cables. It outlines the necessary dimensions, materials, and procedures to ensure compliance with fire resistance requirements and structural integrity.
Specifications
The document specifies the use of reinforcement steel B 500 A with a diameter of 12 mm for joint reinforcement. It also details the use of U-shaped stirrups for constructive junctions, ensuring adequate overlap and spacing for cable loops.
Installation Instructions
The installation process involves setting up precast elements, inserting reinforcement bars, and encasing joints with formwork. The document emphasizes the importance of maintaining a vertical tolerance of 20 mm and provides step-by-step instructions for removing the HLB Loop Box cover and setting up the elements.
Joint Grouting
The HLB Mix joint grout is specified for filling joints, with detailed mixing instructions and substrate preparation guidelines. The grout must be mixed with 2.5 to 3.0 liters of water and applied with care, ensuring a maximum pouring height of 3.5 meters. The grout is designed to be flowable and does not require additional compaction.
Technical Data
The document includes technical data on the properties of the HLB Mix joint grout, such as its consistency, workability time, and compression strength. It also provides guidelines for storage and order information for the grout.
Contact Information
The document lists contact details for HALFEN subsidiaries in various countries, providing phone numbers, email addresses, and websites for further inquiries.
Quality Assurance
HALFEN's Quality Management System is certified according to DIN EN ISO 9001:2008, ensuring high standards in product quality and customer service.

The following notes provide a basic understanding of the load bearing behaviour for the constructive application. However they are not to be considered as normative proofs. 1. Transfer of tension loads perpendicular to the joint The transfer of tension loads results from the overlap of the wire loops (fig. 1). In the area of the loops the compression loads are...
