Which cement is used for pillars?
Installation recommendation for concrete pillars and pillars
1. Preliminary remark
The concrete pillars and pillars are manufactured in accordance with the German concrete standard DIN 18500. Dimensional tolerances of up to ± 4 mm are permitted. The concrete column is hollow and not or only reinforced for transport. The workpieces cannot be loaded and are given their static function by the reinforcement of the cavity. There is a plastic fleece on the inner wall, which must not be removed when filling with concrete, so as not to create a force-fit connection between the workpiece and the inner core. The capitals of the concrete columns are produced separately, so the column shafts can be shortened to the required length.
2. Requirement for assembly
The foundation on which the concrete workpiece is placed requires reinforced or unreinforced normal concrete with a strength class of at least C25. It must be level and frost-proof.
The later locations of the concrete pillars should be taken into account as early as the planning phase in order to incorporate appropriate reinforcing bars in the foundation. Otherwise, reinforcing bars must be anchored in the foundation afterwards. The workpieces are placed over the protruding reinforcement and placed on the foundation. Before this, a layer of mortar is applied to the foundation to level out any unevenness. The vertical alignment of the concrete column has to be done from two adjacent side views. In the case of the concrete pillars, the capital is then placed on top and fixed centrally. It is attached with an adhesive mortar. Finally, the cavity of the concrete pillars and pillars is filled with concrete (at least C25 or according to the static requirements). A complete backfill is achieved by gently shaking it. Avoid cavities in the elements.Danger:
The head surfaces of the concrete pillars and pillars must be sealed watertight. This is the only way to avoid frost damage
4. Optical works
In the case of the concrete pillars, the joint from the shaft to the capital is filled with white adhesive mortar. In the case of concrete pillars, the adhesive mortar in the gap between the pillar and the cover must be smoothed off so that an open drip edge remains all around. Smaller flaws or chipping on the workpieces must be leveled with a white fine filler. At the end of the work, the concrete columns should be treated with a suitable surface protection. To do this, they must be free of grease, dirt and dust.
5. Concrete pillars variants
The concrete column can be lengthened to a certain extent by raising the base plates. Before placing the order, the overall dimensions must be determined accordingly.
Shortening is also possible by shortening the shaft ends according to the specification. Due to the taper of the shafts, the diameter and thus the limited capacity of the capital must be taken into account.
The inside diameter can be enlarged to a small extent.
Halving the concrete pillars is possible
The concrete pillars and pillars are given a static function by the reinforcement of the cavity. Both the reinforcement cage and the steel pipe are subsequently poured into the concrete workpiece.Danger:
The load-bearing core, which fills the cavity of the workpiece, must be higher than the workpiece itself. The statistical load therefore lies on the core and in no way on the concrete column or the concrete pillar. The individual load bearing capacity of the concrete pillars and pillars are different depending on the order. As a result, the reinforcement specifications are also different. Statics commissioned by the customer is a prerequisite for determining the permissible reinforcement. No frost may affect the components during the setting process.
