Description

TECHNICAL FIELD

The present invention relates generally to a plastic pile driver, particularly for driving into the ground.

TECHNICAL BACKGROUND

Rammprofile are post-like components that are used for a simplified, constructive, and static design of a transition between a support structure and a floor. The loads of the supporting structure can be transferred to deeper and more stable layers of soil by means of ramming profiles. Due to a comparatively simple basic geometry, ram profiles represent an inexpensive and simple alternative to conventional foundations made of concrete, reinforced concrete or screw foundations.

There are generally known designs of ramming profiles made of metallic C or U profiles with an additional coating. The coating serves as protection against corrosion from corrosive media in order to extend the durability of the ram profiles at the place of use. The medium can be, for example, a (earth) ground or another environment. The protection used on the profiles is divided into active and passive corrosion protection. With active corrosion protection, the metallic profile is shielded from the corrosive medium by the coating on the surface of the profile acting as a sacrificial anode in relation to the more precious core material of the profile. This is often done with a layer of zinc applied to the metallic profile. With passive corrosion protection, protection is achieved by means of an anti-corrosion agent that is applied to the metallic profile. This is often done with a plastic coating that is largely insensitive to the corrosive medium in question (e.g. an acidic soil composition). Depending on the medium, the plastic coating can be made of polyurethane or epoxy, for example.

Out of DE 20 2017 104 703 U1 a rammed foundation is also known, the base body being an omega plate, preferably sheet steel. The complete ramming foundation is made of several parts and has been galvanized in a zinc electrolyte.

The field of application for ram profiles is very diverse. Especially on difficult ground conditions or terrain that is difficult to access, ram profiles prove to be advantageous due to their easy handling. However, metallic ram profiles have a high dead weight. Difficult soil conditions can include acidic soils, since the acidic soil acts as a corrosive medium compared to a metal profile and significantly reduces the durability of the rammed profiles if the coating is damaged. A pH value below 7.0 is referred to as acidic soil. The lower the pH value, the more acidic the environment.

Due to the planned energy turnaround in the coming decades, the demand for solar systems will also increase continuously. In addition, existing roofs can be used for smaller solar parks. In order to be able to meet the energy demand, however, the use of open spaces for larger solar parks is unavoidable. The geographical selection of the location is primarily made in favor of the best possible energy yield from the solar systems and less according to the soil conditions.

Out of DE 10 2014 008 078 A1 a solar module arrangement is known, the solar module arrangement having a support arrangement. In one embodiment, the support assembly is provided with a screw foundation or a rammed foundation so that the support assembly can be founded on or in the ground.

For this purpose, ramming profiles are rammed into the ground at the foundation. The ramming depth depends on the profile geometry of the ramming profile, the soil conditions and the necessary load capacity. Depending on the dimensions of the ramming profiles, ramming can be done using manual or automated ramming or vibration devices. The force is introduced via the end face facing away from the floor. The partial shock-like load introduction via the front face results in the problem that the previously applied coating can become detached from the ram profiles due to very high mechanical forces. In addition, there is a high shearing force of the soil, which also affects the coating when it is driven in. This can damage the corrosion protection and significantly reduce the service life, for example in acidic soil. Once the ram profile has been rammed in, there is hardly any way of subsequently checking the condition of the coating.

The present invention is based on the object of providing a driving profile in which the above-mentioned disadvantages are at least partially eliminated.

SUMMARY

The present invention solves this problem. According to a first aspect, the present invention provides a driving profile comprising a Base body for ramming into a ground, the base body extending along a longitudinal axis, the ram profile serving as a foundation for a supporting structure, the cross-sectional arrangement of the base body comprising a first functional cross section and a second functional cross section, both functional cross sections having an open cross section, the first and the second functional cross-section has a different inner geometry and outer geometry, the cross-sectional arrangement being symmetrical to an axis of symmetry, the ramming profile being made of plastic in one piece.

Due to the high mechanical loads when driving in and due to the operating loads that occur (static and dynamic loading forces and moments) in use, it is advantageous to design the cross-sectional arrangement of the plastic ramming profile according to these loads. A load-oriented design of the cross-sectional geometry counteracts damage due to ramming and subsequent use.

Depending on the requirement, the dimensions of the second functional cross section can be smaller, the same as, or larger than the first functional cross section.

The ramming profile is driven vertically into the ground along the longitudinal axis using a ramming or vibrating device known for this purpose.

The Rammprofil is preferably made in one piece. A cost-effective serial production can be realized in the pultrusion process. Depending on the requirement and functionalization of the cross-sectional arrangement, the ram profile can also be made in several pieces.

DESCRIPTION OF THE EMBODIMENTS

Before a detailed description of 1 the following general remarks on the embodiments.

The term "solar system" is an umbrella term and describes a technical system for converting solar energy into other forms of energy. Depending on the working principle, solar systems can be divided into three basic types; thermal solar systems, thermal solar power plants, and photovoltaic systems can be divided.

The term “different” in claim 1 means that the inner geometry or the outer geometry of the first and second functional cross sections are not characterized by a common basic geometric shape. The geometries or the outer contours of the cross-sectional arrangement should be designed in such a way that they are not defined by a common, uniform, overarching, possibly symmetrical geometry (e.g. circle, square, rectangle, etc.).

There are embodiments in which the ram profile is preferably made of a thermoplastic material, more preferably a polyvinyl chloride (PVC), more preferably a hard polyvinyl chloride (PVC-U), more preferably an unreinforced PVC-U. Because the ram profile is made entirely of plastic, there is no need for an additional anti-corrosion coating. By eliminating the coating, the surface becomes less sensitive to ramming and shearing. Material substitution can eliminate the problem of material corrosion.

Thanks to the plastic construction, the profile costs can be significantly reduced in comparison to conventional metal rammed profiles, also because the profiles can be reworked on site without special tools. In addition, the weight of the ram profiles is reduced, which means that Trans port and storage costs can be saved and on-site handling is made easier.

Thermoplastics can preferably be used for the serial production of the rammed profiles. Due to the fact that thermoplastics can be melted again, the ram profiles can be mass-produced in a continuous pultrusion process. In addition, thermoplastic ramming profiles are easier to recycle after their useful life.

Depending on the requirement profile, other plastics can also be used, examples of which are: epoxides, polyurethane, polyoxymethylene, acrylonitrile-butadiene-styrene copolymer, polyamide, polypropylene, or polycarbonate. Modified plastics can also be used.

Soil can be acidic, neutral or alkaline. Acidic soils have a pH value of less than or equal to 7. Polyvinyl chloride (PVC) or polyurethane (PUR) are particularly suitable for acidic soils. Due to its mechanical properties, rigid PVC is preferably used in its pure form. Because there are no reinforcing fibers, the material is less brittle, which reduces the risk of splintering when rammed in.

There are embodiments in which the first functional cross section preferably has a C-, U- or Omega-shaped cross section and more preferably a C-shaped cross section. The second functional cross-section preferably has a different C, U, T or Omega-shaped cross-section, more preferably a U-shaped cross-section, with the first and second functional cross-sections comprising a common support web, with the first functional cross-section having receiving legs and the second functional cross-section has stabilizing belts.

Ramming profiles can serve as a foundation for a supporting structure on open spaces. Due to the connected support structure, static and dynamic forces and moments can act on the ram profile. In addition, an earth pressure acts on the ram profile, so it is advantageous to take into account the expected horizontal earth movements and an expected lateral pressure that acts on the ram profile in a cross-sectional geometry. In addition, the ramming profile must withstand buckling and buckling loads during ramming. Under real conditions, different loads can also overlap.

A subdivision of the cross-sectional arrangement into at least two functional cross-sections therefore proves to be advantageous. The combination of open cross-sections, which are connected via a common support web, can be statically and functionally advantageous. With this arrangement, an external torsional load can be adequately counteracted despite the open cross-sections. Depending on the subsequent application, the first and second functional cross section can be designed with a different geometry.

• Ix: 2100 cm⁴ bis 2600 cm⁴, vorteilhafterweise 2356 cm⁴;
• I_Y: 700 cm⁴ bis 950 cm⁴, vorteilhafterweise 870 cm⁴.

In an advantageous design and taking into account bending and torsional stress, an axial area moment of inertia I in the x and y direction can have the following values (the axis designation results from 2 ):

• Ix: 2100 cm ⁴ to 2600 cm ⁴ , advantageously 2356 cm ⁴ ;
• I _Y : 700 cm ⁴ to 950 cm ⁴ , advantageously 870 cm ⁴ .

• Wx: 2100 cm³ bis 2400 cm³, vorteilhafterweise 2243 cm³;
• W_Y: 90 cm³ bis 130 cm³, vorteilhafterweise 117 cm³.

A section modulus W in the x and y direction can have the following values:

• Wx: 2100 cm ³ to 2400 cm ³ , advantageously 2243 cm ³ ;
• W _Y : 90 cm ³ to 130 cm ³ , advantageously 117 cm ³ .

The first functional cross-section has receiving legs that can serve as an interface to any functional element (e.g. an assembly or support structure for superstructures).

The second functional cross section with its stabilization straps can serve as a static reinforcement element for the first functional cross section.

There are embodiments in which the cross section of the base body has locally different wall thicknesses in accordance with the static and functional design, with the wall thickness of the support web being greater than the wall thickness of the receiving leg. Locally varying stress distributions can occur in the cross-section as a result of external loads. With knowledge of the occurring mechanical stresses, the wall thicknesses can be dimensioned accordingly. Areas subjected to heavier loads have a greater wall thickness, areas subjected to lesser loads have a lower wall thickness. The wall thickness can be adjusted depending on later conditions of use. In the case of low loads, material and weight can also be saved as a result.

There are embodiments in which the ram profile includes coupling areas, the coupling areas being arranged along the longitudinal axis of the base body. The coupling rich is partially surrounded by the receiving legs and serves as a local interface on the ramming profile to connect the supporting structure.

There are embodiments in which the coupling areas are designed as through openings. The coupling areas are local connection points along the longitudinal axis. In an advantageous embodiment, the through-openings are arranged as through-holes in the area of the support web. The through openings can also be arranged in the area of the receiving legs. In order to be able to subsequently adjust a height, it is advantageous to provide a plurality of openings in the area of the support web along the longitudinal axis. With a solar system, an orientation and an angle of inclination can be set.

There are embodiments in which the inner area of the first functional cross section acts as a guide rail along the longitudinal axis, with the ramming profile being connected to the connecting profile in an overlapping manner via the guide rail, with the external geometry of the connecting profile corresponding to the internal geometry of the first functional cross section, with the connecting profile being in the transverse direction can be positioned and centered via the support web and the receiving leg and can be fixed in the direction of the longitudinal axis with a screw connection or pin connection via the through-holes of the ramming profile and via the through-openings located in the connecting profile. The connecting profile can serve as a connecting element between the ramming profile and the supporting structure. The outer geometry of the connecting profile can be connected to the inner geometry of the ramming profile in such a way that the connecting profile is positioned in a form-fitting manner along the guide rail in the ramming profile. In an alternative embodiment, the ram profile can be positioned in the connection profile.

With this arrangement, the transverse and horizontal loads, which are transferred to the ramming profile via the connecting profile, can be introduced uniformly into the ramming profile via the receiving legs and the support web.

The ramming profile and the connecting profile are connected to each other so that they overlap. Due to the overlap, the connection area (L) can be increased and the connection point can absorb greater loads. In addition, the wall thickness in the area of the overlap is increased. The selection of the appropriate overlap length depends, among other things, on the tensile strength and the wall thickness of the weaker material and the later maximum load in use.

The connection profile can be connected to the ramming profile via the coupling areas along the longitudinal axis or a vertical axis. Depending on the requirement profile, a detachable or non-detachable connection can be provided. Connections can be: screw connections, pin connections or press connections. Non-detachable connections can be: Welded connections, soldered connections, adhesive connections, riveted connections, press connections or shrink connections. In an advantageous embodiment, the ramming profile and the connecting profile are fixed to each other in the area of the two supporting walls with screw connections in a positive or non-positive manner.

There are embodiments in which the ramming profile is connected to a connecting profile made of a metal material, with the bottom face of the connecting profile facing the ground being arranged at a distance D from the ground. The connection profile can be designed as a coated or uncoated metal material. Here, the connection profile can also be made of a metal material that is unsuitable for the floor. To avoid corrosion, the connection profile can be arranged in such a way that it has no contact with the ground. The lower face of the connection profile is positioned and fixed at a defined distance above the floor.

There are embodiments in which the supporting structure is a solar module, more preferably a photovoltaic module, which is connected to the ramming profile via the connecting profile. In another application, the support structure can also be connected directly to the ram profile.

There are embodiments in which the support structure was founded with ramming profiles, with several ramming profiles and solar modules serving as the foundation for a solar system and/or a solar park. The use of the ramming profiles according to the invention makes it possible to set up solar systems or solar parks in regions where the difficult soil conditions have hitherto made it difficult to establish a foundation with ramming profiles, for example in regions with acidic soil due to contact corrosion.

There are embodiments in which the length of the ram profile protruding from the ground includes UV protection. The ramming profile can be made of a plastic that has only limited resistance to UV radiation. Driving the ramming profile into the ground provides natural UV protection for the rammed part of the ramming profile. The part of the ram profile that protrudes from the ground for the coupling can also be partially coated are provided, which is UV resistant. Alternatively, the UV resistance of UV-sensitive plastics can be improved by adding additives. Examples of additives are; UV stabilizers or a black coloring.
