tryckförankningar

Tryckförankringar, often translated as compression anchors or expansion anchors, are mechanical devices used to fasten objects to solid materials like concrete, brick, or stone. Their primary function is to create a secure hold by expanding or pressing against the walls of a pre-drilled hole. This expansion generates a strong radial force that resists pulling and shear loads.

The most common type of tryckförankring operates on an expansion principle. A bolt or threaded rod is inserted into a hole, and as it is tightened, an internal mechanism forces an expansion sleeve outwards. This sleeve wedges itself tightly against the sides of the hole. Another variation uses a wedge system where a cone-shaped element is driven into the sleeve, causing it to expand.

These anchors are widely used in construction for attaching a variety of items, including structural elements, brackets, pipe supports, and facade systems. They are particularly useful when the base material is dense and strong enough to withstand the outward pressure generated by the anchor. The selection of the appropriate tryckförankring depends on factors such as the load requirements, the type of base material, and the environmental conditions. Proper installation, including drilling the correct hole size and depth, is crucial for ensuring the anchor's performance and safety.
