So that the corner post can be "connected to a high-voltage pylon" as an example, "a sleeve-shaped AHoataatuek is attached to the upper end of the post, into which the 'dole post is acetate, whereupon the inside of the Ansats-r piece and the the space around the extension is filled with concrete. In the case of piles that consist of a box composed of U-profiles, for example, the upper part serves as an extension piece into which the corner post is inserted * However, this embodiment is only intended for piles that do not have to transfer excessive forces into the ground, because the friction between the smooth surfaces of the box and the concrete maase is too low *

another embodiment such as a sleeve-shaped one Extension piece - which is also referred to as a quiver consists in the fact that BIeone is usually square Box are welded together, the inside preferably protruding at its corners protruding into the concrete mass Parts - so-called Knajgen - so that the Forces that act on the concrete mass filled in the quiver are properly transmitted to the pile can. The Jickstiel itself is also included aolchen lugs provided, which are completely enclosed by the concrete mass in the quiver.

In view of this, the da.ii t / alls of the quiver constitute a closed surface, and it is not unusual DAJ the corner post obliquely to Köcherachs · be used must have the the Köchere be relatively large querschnittaabmesaungen, thus also with a corresponding oblique position the corner handle the necessary binding depth in the quiver is achieved.

Driving a rfahlea with a quiver requires about it In addition, careful monitoring of the hamming process

with a view to maintaining small pile-driving tolerances, because - in the striving for the yuereohnitt of the Koohers bo to keep as small as possible - for the introduction dee üokstieles only a great installation game available »Blows

A particular disadvantage, however, is that an extension of an i pale with a quiver is a prerequisite that a new quiver is welded to the extension piece.

But Daa means that one quiver has no legs Two corresponding uses can be found, which is why auoh

all the effort involved has become worthless.

In order to avoid this disadvantage, it has already been proposed that a sleeve-shaped extension piece in the form of a Form fork and only weld this fork at the construction site. The fork pieces consist of profile iron, for example U- ^ isen, which are with their btegteile face opposite; are on the web parts within the fork lugs welded on? . like that also with a » usual quiver of tall iat. By at the construction site The foundations are required for welding way more expensive. On top of that, uai in most In cases it must be ensured that the groundwater that collects in the excavation must be sucked off so that the welding work - which is not normally under water can be carried out - carried out in accordance with precautionary measures can be

However, these works make an extra effort is particularly at time when required for t he suction of the water in the excavation equipment are transported to the construction site rau3 _e

The excavation must also be relatively large in cross-section, since a foundation pile with a small amount of support is at β-atuok in the form of a fork and this fork is a static one Reinforcement must be attached, which naturally takes up a considerable amount of space

In addition, you can also weld on the tabs f Ur the fork in the excavation itself can only be made upside down, which is a careful job requires, which can only be carried out or carried out by a skilled welder; for the security of the transmission of power depends to a large extent on the Good of the Aohwelßnaht.

The invention has the task of providing a bus a hol u uniform extension piece existing connection device to a foundation pile au improve, in particular 30 to train that dchwtlßarbeiten on the Construction site to be avoided as far as possible and that an extension of a ι fahlechaftea in the way mtigllofe 1st, that the extension piece can be used

Lau is achieved by clad the ände of hülsenfurmi & en endpiece aie jiruktur a Gittere possess dao elongated by vertical corner members, and <l ^uer to extending preferably horizontal connecting parts, wherein the Kakteile of Ansatzetüokee connected to the Gran manure pile are preferably verachwciiit. '

This formation of the sleeve-shaped extension piece results A possibility of all forces going out of the kkatiel over the two horizontal connecting parts and the Kckteile existing concrete composite in the pile to be initiated, as the grid itself acts as a static reinforcement.

The inner rhyme of the extension let ron completely free protruding parts, whereby with given installation apiel for the üokatiel the cross-section of the sleeve-shaped Anaatzatüokes near the training according to the invention can be kept smaller, as there are no catches that take up additional space

The formation of the sleeve-shaped extension piece in the form a lattice structure also enables the introduction dea üokstielee in such a way that the lower part of the iückatieles to penetrate a certain amount through aaa grid can "from which it follows in turn" that the cross section "dca hiilaen-shaped Anaatsatüokee in the form of a Lattice girders can be smaller, ala with one Quiver.

It is particularly advantageous, however, that a (round with the adapter according to the invention without further ado can be extended because the welded on the i'fahl üickteile as connecting parts for the extension kit can serve

Since the lengthening of an x ^J wale has to be carried out frequently on the construction site, this type of formation of an approach stack represents a great step forward.

In the case of precast concrete piles, this formation of the extension piece gives the possibility of a finished concrete pile head in the first place Extend the eu by placing a sleeve-shaped sleeve made of metal on the prefabricated concrete pile head. The hood is attached to which the ijckteile of the sleeve-shaped The extension piece can be welded
