Definitions
- the present invention relates to a reinforced concrete foundation system for the execution of superstructures that promptly transmit large axial loads, shear stresses and / or bending moments, such as wind turbines.
- the foundation object of this invention is formed by an upper slab of reinforced concrete poured "in situ", of polygonal or circular plan, stiffened inferiorly by ribs of reinforced concrete of rectangular or trapecial section arranged radially.
- This new foundation aims to significantly reduce the costs of executing traditional foundations for this type of superstructures, considerably improving the completion times.
- foundation slab of different configuration in plan: square, circular, hexagonal, octagonal, etc.
- the edge of the slab can be constant or variable in order to optimize the consumption of concrete.
- EP1074663 is known, which is a An example of a foundation with three stabilizers symmetrically located around a central support that has the disadvantage of presenting very little surface contact with the ground with the consequent increase in tensions applied to the ground, as well as the seats.
- PCT patent application WO2004 / 101898 presents a circular foundation based on prefabricated triangular sections. This solution requires a complete emptying of the excavation, resulting in an inverted T-concrete section that does not entail any structural advantage, since the width of the compressed concrete head is very small. This will mean that in the flexural calculation the neutral fiber will be lower and a reduced mechanical arm will be available, increasing the need for reinforcement and considerably reducing the sectional ductility.
- Spanish patent application ES-2347742 describes a cone-shaped foundation together with a lower slab in the form of a flat ring. It is a very complex solution to execute and presents serious doubts about its structural behavior.
- the present invention presents a solution formed by an upper slab of reinforced concrete poured "in situ" of polygonal or circular plan stiffened inferiorly by ribs of reinforced concrete of rectangular or trapecial section arranged radially from a central core.
- the nerves are concreted directly on the previously excavated ground, while the slab rests on the unloved land itself, acting as a lost formwork.
- stiffening ribs can be executed with concrete "in situ” or they can be prefabricated, always working in solidarity with the upper slab, as well as they can be of constant or variable edge, either staggered or with constant slope, reducing their section as we move away from the central core of the slab.
- stiffening ribs that are completely prefabricated, there will be projecting reinforcement for the connection with the slab executed "in situ".
- the stiffening ribs could be made by semi-manufactured elements, such as with double-walled pieces that remain embedded when the concrete is poured to form the foundation.
- the foundation object of this invention is formed by an upper slab of reinforced concrete poured "in situ" of circular or polygonal plan stiffened inferiorly by ribs of reinforced concrete of rectangular or trapecial section arranged radially.
- the reinforced concrete ribs are of trapezoidal section, they will be wider at the top in contact with the slab, to take advantage of the excavation slopes as lost formwork, increasing the resistant section of concrete.
- This foundation is obtained by pouring the concrete "in situ" directly on the undrawn ground that acts as a lost formwork. Prior to pouring concrete, all the necessary reinforcement of the slab and ribs is placed.
- a strong T-shaped section of high structural efficiency is generated, as the compressions are absorbed by the upper slab and the tractions are resolved by the reinforcements housed in the lower part of the interior of the stiffening ribs.
- jumps can be made in the excavation of the nerves, managing to vary the edge of the same reducing as we move away from the center of the slab .
- These nerves can be executed with concrete "in situ” or they can be completely or partially prefabricated, always working in solidarity with the upper slab.
- the upper slab does not necessarily have to be formed by a single piece that completely covers the stiffening ribs from its inner end to its outer end, but said upper slab can be formed by several portions, a first portion covering the central core of stiffening nerves
- portion refers to a part of the central slab that is physically separated from other possible portions of said slab.
- the central core is the place where the inner ends of the different stiffening ribs meet, and therefore it is considered to be an integral part of said stiffening ribs.
- the simplest configuration of the upper slab of the invention coincides with a single portion of the upper slab that covers only the inner ends of the stiffening ribs, that is, covers only the central core.
- the central slab is formed by two portions: a first portion covering the central core, and also a second portion separated from the first and having a perimeter ring shape connecting the outer ends of the nerves. It is thus possible to reduce the amount of concrete used while maintaining a good foundation behavior, since the second portion of the slab that connects the outer ends of the ribs provides rigidity to the assembly.
- the central core also has a hollow cylinder shape, thus saving even more concrete and lightening the foundation.
- Figure 1 shows a perspective of the system as a whole.
- Figure 2 shows a perspective of the foundation with nerves of stepped variable section.
- Figure 3 shows a longitudinal section through one of the nerves.
- Figure 4 shows a cross section.
- Figure 5 shows a perspective of the foundation with trapezoidal ribs.
- Figure 6 shows the T-shaped sturdy section object of the foundation of the present invention, as well as tensile-deformation diagrams for flexural calculation.
- Figure 7 shows the resistant section in inverted T-shape, as well as the corresponding tensile-deformation diagrams for the flexural calculation.
- Figure 8 shows a top perspective of an improved foundation in accordance with the present invention where the upper slab covers only the central core.
- Figure 9 shows a top perspective of another foundation improved in accordance with the present invention where the upper slab comprises a first portion that covers the central core and a second portion that connects the outer ends of the ribs.
- Figure 10 shows a lower perspective of another foundation improved in accordance with the present invention where the central core is lightened by being in the shape of a hollow cylinder.
- Figure 1 shows a perspective of the system as a whole, formed by a foundation (3) and a shaft (4) in a construction for a wind turbine.
- a foundation formed by an upper slab (1) of reinforced concrete poured "in situ" of polygonal plant is observed, although it could take any other form such as for example circular, inferiorly stiffened by reinforcement ribs (2), made by reinforced concrete of rectangular section and arranged radially.
- the T-section (object of the foundation of the present invention) is structurally more efficient for the type of efforts to which the foundations will be subjected object of this patent, providing a 20% higher flexural strength.
- the sectional balance requires that the resulting traction supported by the reinforcement be equal to the volume of compressions supported by the concrete.
- the T section has a much wider compression head, which allows the neutral fiber to remain elevated and the mechanical arm is noticeably larger than in the case of the inverted T section. Additionally, as we can see from the x / h ratio, which indicates the depth of the neutral fiber with respect to the section edge, the ductility is much greater in the T section, allowing the redistribution of efforts in plastic regime.
- Figures 8-10 illustrate examples of embodiments where the concrete slab (1) does not cover all stiffening ribs but only a part thereof.
- Fig. 8 illustrates an example of a foundation comprising an upper slab (1) formed by a single portion covering the central core (7) (7) of the stiffening ribs (2).
- Fig. 9 illustrates another example of a foundation where the upper slab (1) is formed by two portions: a first portion (1) similar to that shown in Fig. 8 covering only the central core (7) of the nerves ( 2) stiffeners; and a second portion (6) in the form of a perimeter ring that connects the outer ends of all stiffening ribs (2). This allows to reduce the total volume of concrete used while maintaining a great rigidity of the whole.
- Fig. 10 shows another example of a foundation that has an upper slab (1) similar to that of Fig. 8 covering only the central core (7) of the stiffening ribs (2), and where the core (7) Central is shaped like a hollow cylinder. It is thus possible to double lighten the weight of the assembly and the amount of material compared to other embodiments of the invention where the slab (1) completely covers the ribs (2) and the central core (7) is solid.
- the procedure for carrying out the foundation could include the following steps:
- jumps (5) can be made in the excavation of the nerves, as reflected in Figure 2, managing to vary the edge of them shrinking as we move away from the center of the slab.
- Said ribs can be executed with concrete "in situ” or they can be totally or partially prefabricated (such as with semi-prefabricated double wall elements), always working in solidarity with the upper slab.
