Description

Ground anchoring device compact

Object of the invention

The present invention relates to a anchoring device for fixing to the ground of different types of objects and structures, such as those used as a support for solar panels, and in general for fixing to ground of any type of post or similar.

The object of the invention is to achieve a structurally simple anchor, consequently economic, but with optimal performance from the point of view functional.

Background of the invention

There are countless elements or structures that under normal working conditions they must be fixed to the ground, the natural terrain being understood as such, as happens for example in installations for capturing solar energy, on fences advertising, etc.

Leaving aside the classic anchoring systems that remain embedded in a concrete shoe implanted in the land, because of being slow and expensive elaboration, the anchoring devices in this area are based on a philosophy functional similar to micropilotage, and consists of a kind of nail or screw, based on a body tending to the configuration conical, and with a helical thread, so that the device anchor is introduced into the ground by a combined action of axial effort and rotation on it.

As an example, the device can be mentioned for fixing bars, posts, masts or the like in the soil, which constitutes the object of the European Patent with number of publication 2217798, device that, as previously said, it tends to conical configuration, based on several sectors with different degree of conicity, combined with sectors cylindrical, presented the anchoring device a tip pyramidal trunk, quadrangular, from which a first trunk-conical sector is established and massif and a second sector also trunk-conical but hollow, both externally affected by a helical septum in thread fillet functions, to facilitate the penetration of device in the field.

This solution although it is valid from the functional point of view, presents as fundamental problem its complex processing and high cost, derived from the configuration partially empty and partially hollow conical of the body of the anchoring, and also the conical configuration of its helicoid Exterior. As well as a loss of resistance on the grounds that because of its hardness to make a pre-drill.

Description of the invention

The anchoring device that the invention proposes, especially designed for compact floors, resolves the problem was fully satisfactory before exposed, constituting a structurally simple solution, with a manufacturing cost considerably lower than the device of said European patent and with benefits Similar. Superior for very compact or rocky terrain.

For this and more specifically the device Anchoring that is recommended is constituted by a tube cylindrical, whose cost is minimal when constituting an element of market, cylindrical tube that incorporates in one of its two halves, fixed by welding, a helical partition that converts said tube in a kind of screw fixable within a hole or pre-drill previously practiced on the ground, finishing off the opposite end of said tube cylindrical in a mooring flange conveniently perforated for allow fixing of the post or structure in question.

The configuration also generally cylindrical of the helical partition makes its manufacturing cost minimal, to be able to perform continuously, and the apparent less stiffness structural of the device, due to its hollow interior, is not such in practice because during its assembly on the ground, that is, during screwing, it is filled inside with earth, which makes it a solid element that sees substantially increased its resistance against possible stress tending efforts.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows, according to a representation schematic in perspective, an anchoring device on floors compact made in accordance with the purpose of this invention.

Figure 2.- Shows an elevation view side of the same device.

Figure 3.- Shows, finally, a view axial of the device of the previous figures.

Preferred Embodiment of the Invention

In the figures outlined it can be seen as the anchoring device that the invention proposes is constituted from a tubular body (1), cylindrical, whose axial dimension, its diameter, wall thickness and nature of the constituent material of the same, can be variable depending on the requirements specific to each practical and concrete use planned for the same, tubular body (1) which, as previously stated, It is intended to be inserted in a hole previously made in the terrain, due to the compact nature of the latter.

The cylindrical tube (1) incorporated in approximately one of its two halves, a helical partition (2) that configures a kind of diameter thread steak constant, and that is fixed to the tube (1) by welding.

Logically this helical thread steak (2) It is intended to dig into the ground, specifically on the pre-drill wall made therein, by an action combined axial thrust and turn, supplied by a machine proper assembly.

Finally the cylindrical tube (1) is finished off by its opposite end to thread steak (2) in a tie-down flange (3), preferably consisting of a disc fixed by welding to the aforementioned end of the cylindrical tube (1) and provided with a plurality of holes (4) properly distributed and dimensioned for fixing the structural element of which Try in each case.

The diameter of the drill made in the field it must be adequate for the mouth to mount the device front and open (5) of the cylindrical tube (1) cause a material shedding, that is, a landslide, which finally ends up entering through said mouth (5) in the inside the tube (1), solidifying it to enhance its resistance mechanical against possible stress tending efforts side.

Logically the anchoring device allows its manufacturing to any extent, both for the cylindrical tube (1) as for your helicoid (2), and its manufacturing can be done in any appropriate material, obviously including steel stainless.

Claims (1)

1. Anchoring device on compact floors, of the type that form a kind of screw topped by one of its ends in a tie-down flange for the structural element to be fixed to the ground, characterized in that it incorporates a tubular, cylindrical and hollow body, of constant section, which is topped by one of its ends in the corresponding tie-down flange, and which presents its opposite open end, end in the vicinity to which it incorporates, fixed by welding to it, the helical tab that constitutes its thread, also of constant section.
