Afstandhouders

Afstandhouders are components used in various fields, primarily in construction and engineering, to ensure a specific, consistent separation between elements. In concrete construction,afstandhouders, often called rebar chairs or spacers, are critical for maintaining the correct concrete cover over reinforcing steel. This cover is essential for protecting the rebar from corrosion and for the structural integrity of the concrete element. They are typically made from plastic, concrete, or metal and are placed at regular intervals to support the rebar cage at the desired height within the formwork before the concrete is poured.

Beyond concrete, the term afstandhouder can refer to similar devices in other contexts. For example, in automotive engineering, they might be used to maintain clearance between different components to prevent interference or vibration. In furniture manufacturing, they can ensure consistent gaps between panels or parts. The fundamental purpose remains the same: to create and maintain a predetermined space. The design and material of an afstandhouder are chosen based on the specific application, considering factors such as load-bearing capacity, environmental resistance, and compatibility with surrounding materials. Their precise placement and function are vital for the performance and longevity of the assembled structure or product.
