Prefabricated point foundations  

PREFABRICATED POINT FOUNDATIONS FOR SHALLOW FOUNDATIONS

The prefabricated point foundation is a reinforced concrete element consisting of bonded reinforcement and concrete, which acts as a formwork before the final concreting on the construction site. The geometric dimensions and the amount of steel reinforcement are determined by static calculations made on the basis of the load distribution of internal stresses and the bearing capacity of the soil.
With a prefabricated reinforced concrete foundation, we avoid casting and reinforcement on the construction site, since the foundation is already precast in the factory. This avoids the effects of the weather on the construction site, and above all speeds up the work. The reinforcement of the foundation is adapted to each building individually, depending on the loads and the terrain on which the building stands.


DIMENSIONS

Prefabricated foundations can be manufactured in various dimensions to meet all structural requirements.
The dimensions of the prefabricated point foundation are 2.5 x 2.5 x H, where the height H is adjustable according to the static requirements of the individual construction. Also, the width of the foundation is adjustable by implementing a wider AB base plate, which is connected to a prefabricated point foundation of fixed floor plan dimensions. 

ASSEMBLY

During the assembly process, the precast foundation is placed on the pre-prepared concrete base (1), then the precast column together with the bent rebars is placed on the precast point foundation (2). The upper reinforcing bars are inserted into the foundation and the column is fixed to the foundation with steel plates (3). the foundation is filled with concrete (4). The work is completed by removing all fasteners (5).).
 
Steel angles are used for assembly and alignment of the assembly column. These enable easy, fast and precise assembly.
During the production of the precast foundation, four threaded rods are installed inside the central concrete walls, while the precast column is equipped with eight threaded joints. Using steel angles, anchor threaded rods, metal inserts and screws with nuts, the column is assembled and precisely placed in the desired position.
This system not only enables the alignment of the mounting column with high precision, but also eliminates the need for additional supports during assembly. This system avoids additional support with inclined supports or wedging of the column in the cup.


MAIN ADVANTAGES
- The main supporting armature of the column is anchored directly into the column without interruption. With this, we achieve the highest quality contact between the column and the foundation.
- Greater seismic safety.
- The height of the foundation is much smaller (less excavation, concrete, ...)
- We avoid casting and reinforcement on the construction site.
- Possible execution of the foundation on the floor plate.
- Shorter build time.
 - As we can see in the picture on the left, where different solutions for the foundation of the column are shown, we can see that with this system, the consumption of concrete is lower

- With this foundation method, we can reduce the cost of foundation implementation by up to 40%.
- By increasing the number of prefabricated elements of the building itself, we speed up construction (up to 60%) and greatly reduce unforeseen construction costs.
