The invention is based on the technical problem of forming a post foundation of the type mentioned in such a way that the traffic sign, the support, the mast and the like. without further aids * in particular without the use of casting compounds that require a curing time, is immovably firmly and at the same time taken out removable.

According to the invention, this object is achieved by at least two molded parts with a U-shaped or V-shaped cross-sectional profile, which are guided into one another and whose sliding fits are inclined to their longitudinal axis Have guide surfaces which, with parallel relative movement of the molded parts, bring the same closer together force. ·.

At least one dovetail guide is expediently used as a sliding fit intended"

According to a preferred embodiment at Bplel, the molded parts are designed angularly, with trapezoidal dovetail strips and on the end face of a leg ■ each molded part the inside of the other leg coaxially extending dovetail grooves are formed and the molded parts due to the opposite inclination of their dovetail bars differentiate between dovetail grooves *

The invention is explained below with reference to the drawing of some Embodiments explained:

In the embodiment of Figures 1, 2, 7, 8 the elongated bar-shaped molded parts 1, 2 are designed angular. On the face. I ¹¹ . ^{1 of} a leg I ^{1 of} each molded part 1 or 2, two trapezoidal dovetail strips 1 are formed on each. The central axes Tb-b) of these strips form an angle of approximately 50 ° with respect to the longitudinal axis (a-a) of the molded part.

However, this angle can also be significantly smaller or larger. On the inside of the other leg I ¹ 'dovetail grooves 1 are arranged, the central axes (b - b) of which run parallel to the central axes of the dovetail strips.

_{The two molded parts I 1} 2, which are guided into one another for the purpose of forming the foundation, differ in that they are opposed to one another

IV

Inclination of their dovetail strips 1 or dovetail grooves 1, (see FIGS. 7 and 8).

IV When the post is set, the dovetail strips 1 of one molded part are inserted into the dovetail grooves of the other molded part. When relative movement of the two mold parts against each other, the inclined guide surfaces of the dovetail guides 1 »2> -wodurch..der post force a reciprocal approach of the two mold parts _r directly between the two FormteJ-len is tightened. _... ·, ....

Apart from digging into the ground, there are therefore no further work steps or aids for fastening the post necessary"

If there is a need to replace the post, e.g. a traffic sign to be removed later, so the tension by a oppositely directed relative movement of the two molded parts are released again, for which purpose a winch is used, for example Can be found.

The same prerequisites and conditions of tightening and the loosening of the post also apply equally to the exemplary embodiments in FIGS. 3, 4 and 5, 6. In the exemplary embodiment in FIGS. 3 and 4, one molded part 4 is TJ-shaped

IV designed. The inner surfaces 4 '· ¹ and 4 of its TJ legs 4', 4 ^{lf form the guide surfaces of} a downwardly tapering dovetail groove. This dovetail groove runs parallel to the longitudinal axis (a - a) of the molded part. A dovetail bar 3 'which is formed centrally on the other molded part 3 and also tapers downward is guided in it. As a result of the tapering of the dovetail guide, when the two molded parts 3 »4 move relative to one another, there is a forced convergence that can be as long as possible until the surfaces of one of the molded parts
come into plant.

IV of the one molded part on the surfaces 4 of the other molded part

In the embodiment of FIGS. 5 and 6, the U-shaped molded parts 5, 6 are identical to one another. In the U-legs 5 ¹ »6 · of one or the other molded part or both molded parts are bolts inclined to the longitudinal axis a - a. 7, 8 anchored. The free ends of the bolts engage in corresponding guide holes in the other molded part.

As can be seen from Figure €, the bolts 7, 8 protrude in the position of use of the molded parts, the molded piece passed through. In the over-

protruding section 7 'or 8 · they each have a recess for a conical clamping element 9, IQ .. _A -

Grooves (not visible in the drawing) on the inner surfaces favor the IT or Y-leg of the molded parts tightening the posts.

One of the molded parts of a post foundation can have a notch (recess) G (FIGS. 1-6). This is intended "to a post to be used attached to the eyelet or snap _(bolts, to this at any removal easier to pull out and to prevent rotation of the post excluded.

A recessed grip d is used for easier insertion and removal of the individual foundation parts.

e is a foundation foot for placing the post. The foundation foot is in each case attached to the molded part, due to its shape is the first to be used.

The specific clamping principle enables both posts different cross-sectional shape (square, round, oval) etc. as well as posts of varying thickness with a minimum to tighten to the workload.
