FR2701504A1 - Stake for anchoring to the ground - Google Patents

Abstract

The invention relates to a device making it possible to anchor an element to the ground without having to dig or use conventional techniques. It consists of a metal stake provided with fins and surmounted by a plate intended to receive the object to be anchored to the ground. Once the stake has been driven into the ground, only the plate remains visible and receives the object to be anchored which will be bolted to this plate which is provided with nuts on its inner surface. The device according to the invention is recommended particularly for anchoring any type of urban equipment (street furniture) and the like to the ground.

Description

The present invention relates to a device which makes it possible to fix to the ground using a metal stake all that is usually fixed to the ground by seals with cement, concrete or other traditional means.
The fixing of the material to the ground is usually done by the addition of cement in a hole which lton dug in the ground and in which one will have introduced part of the material to be sealed.

In some cases, part of the material to be sealed was forced into it, but it was not possible to extract the material as easily as it had been inserted, it was necessary to intervene with ruinous means in terms of time and tools, moreover, the place deteriorated
The device of this invention overcomes all these drawbacks
It consists in introducing a metal stake into the ground using a hammer or a pneumatic hammer which will have been fixed on the stake and which by small repeated shocks will allow it to be driven in.
Indeed, in the first case we will have fixed on the plate of the upper part of the stake an intermediate tool receiving the shocks caused by the striking of the mass and in the other case we will have placed on the plate a metal piece connecting the hammer pneumatic.

The user will disassemble the tool and therefore remove the pile from the pneumatic hammer
Once pressed, only the upper stake plate is visible.

It is on this that we can fix by bolting: poles, stakes and other urban furniture, chalets, etc.

According to its embodiment, the pile can receive a plate identical to the one it lets appear and on which one can fix tubes, profiles, wooden pieces, steel cables, or ropes, etc.

On the FIG drawing we represent the plates and the central rods as being round, but they can take other aspects according to the uses that will be made of them, their shape can be modified in order to offer greater resistance to tearing.

The length of the piles is variable because it depends on many parameters such as the nature of the soil, the climatic conditions of the region and of course the use that will be made of it (weight of the material to be attached to it). , the anchor stake, will receive corrosion protection during its manufacture, galvanization, zinc plating, tar, etc.

PLATINUM DESCRIPTlONS

A round plate, or in any other geometric form ()
allowing by bolting to fix the material which is usual meznt fixed to the ground. We presented this turntable with four
threads but it can have as many threads as necessary (Lr)
Its shape can be directly adapted to the use we will have a
as well as its thickness can be determined with use
that the user will impose it.

But in all cases it remains adaptable to the material to be fixed.

It is an integral part of the anchor pile, it is fixed by welding to the central rod as well as to the fins, it becomes
by welding linked to both the central rod and the fins.

 El-allows to transmit in the whole of the anchoring pile the forces, of 'driving by pneumatic shocks or by shocks caused by a metallic mass, just as it will allow Ke to transmit the force necessary for the operation of extraction.

It will be a support table for fixing the material that we will have to fix to the ground using our anchor stake.

This plate therefore constitutes an innovation.

Other fixing methods can be envisaged than screwing
for example the clamping, the keying, the pinning. which will allow
to link the material on this deck.

FINS
The fins have various functions 3
That of guiding the insertion of the stake into the ground, in such a way that
1 depression is done well in the direction decided, that of maintaining
the direction of the depression.

That of transmitting the force inflicted when sinking into the set
ble of the stake, that this force is well transmitted to the whole stake.

 that it is well distributed throughout the stake.

That of maintaining the anchor stake in the perdition of the depression
and that it cannot turn on itself after having pressed it
That of allowing the earth or the material that constitutes the soil to press against the stake, the fins will therefore constitute surfacerd <support therefore will contribute to the general support of the earth against the stake, this will therefore help the solidity of the stake in the ground after sinking.

It is therefore possible to have fins provided with holes, or openings allowing the Earth to be introduced inside the fins, these openings will allow the earth to bind it through the fins,
Just as it is possible to weld the fins no longer in a straight line but in the form of a twist or twist, thus allowing better penetration into the ground.

The number of fins is not absolutely determined by the number of but we can predict 4 and more.

Just as the position of the fins can be provided in the form of squares or 90 X angles, they can be made up of two inverted angles, leaned by welding along the central rod. (j
The fins welded against the central rod give the whole pile a perfect solidity, constitute a perfect connection between the plate and the rod.

DESCRIPTIONS
CENTRAL POLE
Metal piece of round shape or any other section, with a diameter that can be 18 m / m but also stronger depending on the use that will be made of the pile and also according to the nature of the soil to be crossed during the insertion of the stake into the ground. (5)
Also of variable length depending also on the importance of what we will have to fix using this inventory.

The central part is in commercial steel or in a more elaborate steel will undergo a cement treatment after having been forged and hardened
It will be linked by welding to the upper plate and to the fins, so it will be the main and basic element of the invention, because it is by its nature the basic principle of the invention, the other elements are helping parts to the use and solidity.

The central part resembles a carpenter's nail, but it is also the pointrole of a masson due to its design and use
The central rod protrudes above the plate, this excess of about 10 m / m helps to position the tool which will serve to receive the Wolves during the sinking, or the hydraulic action, or the sinking by 11 effort of a jackhammer. (6)
The rod is provided with a point obtained by forging or by other mechanical process. this point will allow better penetration into the ground.

its soaking will resist when penetrating into the ground or in contact with stones and other objects encountered in the ground. / P)
