Reusable concrete point foundation with integrated reinforcement, fixing flange and embedded metal pipes for multiple uses in temporary or permanent structures.

Abstract

Reusable, essentially pyramid-shaped concrete point foundation, characterized by an integrated reinforcement to absorb tensile, compressive and bending forces, a mounting flange located at the upper end and embedded in the concrete for receiving superstructures, as well as two or more metal pipes passing through the foundation, wherein the metal pipes are connected to the reinforcement and completely surrounded by concrete, and the foundation is designed so that it can be lifted, transported and reused after use.

Description

[0001] The present invention relates to a reusable point foundation, particularly for use in temporary or permanent structures, which has a substantially pyramidal base shape and is equipped with integrated reinforcement, a fastening flange, and embedded metal tubes. The foundation serves for the stable, releasable, and transportable installation of structures, installations, or structural elements without the need for a foundation permanently embedded in the ground.

[0002] Current technology includes concrete foundations that are permanently embedded in the ground and are generally not reusable. Such foundations are usually not transportable and must be laboriously dismantled or destroyed after use. In addition, there are temporary foundations made of metal frames or plastic, which are easy to relocate but are severely limited in their load-bearing capacity, stability, and durability.

[0003] The invention therefore aims to provide a stable, transportable, and reusable concrete foundation capable of bearing heavy loads and suitable for various construction purposes. At the same time, the design should ensure that the embedded metal components are permanently protected against frost and corrosion damage, and that the foundation can be easily lifted, relocated, and reused.

[0004] This task is accomplished by a pyramid-shaped concrete point foundation with integrated reinforcement to absorb tensile, compressive, and bending forces. A fastening flange is located at the top of the foundation, firmly connected to the reinforcement and embedded in the concrete. This flange serves to support and fasten a wide variety of building structures. Its standardized design allows different structures, such as columns, modular frames, machine foundations, or lightweight building elements, to be mounted on the same foundation type, eliminating the need for a separate foundation for each application.

[0005] Parallel to the flange surface, two or more metal tubes, preferably made of stainless steel, are guided through the foundation in the upper area and connected to the reinforcement. These tubes serve as penetrations for lifting or rigging equipment and enable the foundation to be lifted, transported, and reused safely. Due to the closed tube design and complete embedding in the concrete, water cannot accumulate in the cavities, thus significantly reducing the risk of frost damage.

[0006] The pyramidal shape of the concrete foundation ensures an even distribution of the load on the ground and simultaneously provides a good point of leverage for lifting with suitable lifting equipment. The foundation height is preferably approximately 80 cm, but can be adjusted depending on the load and operating conditions.

[0007] To increase durability, frost-resistant concrete is used, for example, strength class C30 / 37 with an exposure class of at least XC3 or XC4. The reinforcement and the embedded metal pipes are covered with a concrete cover of preferably 30 to 50 mm to permanently protect them against moisture and environmental influences.

[0008] The point foundation according to the invention is characterized by several advantages. It is reusable multiple times without any loss of load-bearing capacity or stability and allows for quick assembly and disassembly without extensive earthworks. The integrated reinforcement ensures high strength, while the closed metal tubes and sufficient concrete cover prevent frost and corrosion damage. Furthermore, the embedded flange offers the crucial advantage that different types of structures can be mounted on one and the same foundation, which expands the range of applications and significantly improves the cost-effectiveness of the construction method.

[0009] The foundation can be used in both temporary construction, such as for trade fairs, events, modular buildings or mobile facilities, and in permanent building construction, for example for prefabricated houses, lightweight halls, solar power plants or machine foundations.
