Tension rod system for building and hall girder, has metal casings connected with tension rod in force fit, form fit and material fit manner, where metal casings exhibit fire-retardant enclosure including internal teeth

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a tension rod system made from fibrous composite materials, intended for use in building and hall girders. The system uses specially designed metal casings at the ends of the tension rod which are connected by a combination of mechanical fit (force-fit and form-fit) and adhesive (material-fit) methods. These metal casings also provide fire-retardant properties and include internal teeth for improved connection.

Use CasesContent extracted from patent full text and abstract with AI.

• Structural reinforcement of large building halls and gymnasiums
• Components in bridges or truss systems where tension elements are needed
• Fire-resistant construction elements in public buildings
• Applications requiring strong, lightweight, and fire-safe tension rod connections in architecture

BenefitsContent extracted from patent full text and abstract with AI.

• Improved fire safety due to fire-retardant casing and materials
• Enhanced connection strength due to multiple fit methods (force, form, and material fit)
• Use of lightweight fibrous composites reduces the overall weight of structural elements
• Internal teeth in metal casings increase mechanical grip and reliability
• Suitable for modern construction needs requiring both strength and fire resistance

Patent Abstract

The system has a tension rod (1) formed from a fibrous composite material, and connection elements connected to sides of the tension rod. Metal casings (2) are attached on ends of the tension rod by a combination of press connection and adhesive connection. The metal casings are connected with the tension rod in force-fit, form-fit and material-fit manner. The metal casings exhibit a fire-retardant enclosure (4) that is made of hardly combustible fibrous composite material, and exhibit internal teeth (7). An independent claim is also included for a method for developing a tension rod system for buildings and resound girder.
