Clamped wooden supports

When it comes to creating stable and secure foundations for interior spaces, clamped timber props are a popular choice. This type of column can be constructed at the base in a number of ways, including grouting, connection with a slotted steel section or connection of two-part columns with an internal steel profile.

Clamping through potting

One of the most common methods of anchoring timber columns securely and stably in the foundation is by grouting. Here, the vertical loads are transmitted via the contact of the end face, while shear force and moment are introduced into the foundation via pressure at right angles to the grain.

Areas of application and regulations

However, it should be noted that grouted supports should only be used inside enclosed or covered spaces where the average relative humidity of the surrounding air is ≤ 70 % and the supports, including their clamping area, are not exposed to precipitation or other wetness (including that from use). In addition, the foundation base must be at least 0.5 m above the highest groundwater level, unless special measures are taken to keep groundwater away from the foundation. No planned clamping moments from permanent loads may occur.
