DE3212719A1 - Anchoring device - Google Patents

Abstract

The invention relates to an device for anchoring supporting posts, placed on a base plate and connected firmly thereto, for balustrades, crash barriers, sound-proofing walls, and the like in concrete structures by means of bolt-shaped elements which are anchored in the concrete by static friction and are connected to one another by a horizontally arranged anchor plate. The ends of these bolt-shaped elements penetrate correspondingly arranged recesses in the base plate of the supporting post, after the latter has been placed with its base plate onto the anchor plate. The ends, projecting beyond the base plate, of the bolt-shaped elements exhibit continuous slots into which metal wedges can be driven such that a frictional connection of the holding posts with the bolt-shaped elements is formed. To make the anchoring by means of the metal wedges more stable and more simple, the invention provides for each retaining bolt to have in each case two lateral, groove-shaped recesses which are opposite each other and extend horizontally, instead of slots. U-shaped metal wedges are driven onto the resulting bolt sections having walls parallel to one another, which wedges are dimensioned correspondingly to said bolt sections, for the frictional connection of supporting posts and retaining bolts.

Description: ·

The main patent (patent application P 31 50 979.7) relates to a device for anchoring on a base plate attached and firmly connected support posts for railings, guardrails, noise barriers, etc. in concrete structures with bolt-shaped elements anchored in the concrete by static friction and rigidly connected to one another.

With the device of the type mentioned, it is possible to mount the footplate of a support post for railings or the like. Like. To connect firmly to concrete structures in a simple manner or, depending on the need, to dismantle again, being a time consuming screwing or unscrewing 'of parts, which is usually caused by concrete pollution or Rust is very difficult, completely eliminated.

The object of the present invention is to provide the device according to the main patent (patent application P 31 50 97.9.7) to improve further. In particular, the anchoring should be even more stable and simple by means of the metal wedges be feasible without the cross-section of the retaining bolts being weakened.

This object is achieved according to the invention in that each retaining bolt instead of lateral slots, respectively

two opposing horizontally has groove-shaped recesses, such that of guide and Holding lugs limited bolt sections are formed with walls parallel to one another, which are made of wide incisions appropriately designed U-shaped metal wedges added after driving them onto the retaining bolts are, so that by means of the so held and guided on the retaining bolt metal wedges the footplate with the support post after arranging a suitable lining, e.g. from Synthetic resin mortar, which can be positively connected with the retaining bolts between the base plate and anchor plate

This further embodiment of the device according to the main patent (patent application P 31 50 979.7) provides the advantage achieves that even more stable wedges can be used that do not affect the dimensions in their dimensions a slot in the retaining bolt are limited.

Because the wedges encompass the retaining bolts laterally after being driven up, the wedges can be made very wide and stable which contributes to an even more stable and better anchoring of the base plates of the support posts.

By arranging lateral recesses on the retaining bolts for holding and guiding the wedges, a weakening is created of the statically important central cross section of the bolts avoided. This also increases the stability of the anchoring increased even more.

In a further advantageous embodiment of the invention is provided that the incisions of the U-shaped metal wedges a slightly greater width than the width of the bolt section own. This will make attaching the wedges and securing them the same on the retaining bolts and different dimensional tolerances are compensated.

It is also advantageous that. the U-shaped metal parts are beveled either on their upper or lower surfaces at the same angle, and that also two U-shaped metal wedges are drivable one above the other on one bolt section each so that they are each surfaces lying on top of each other This results in a better Surface contact of the wedges arranged one above the other and thus a firm connection achieved.

The invention is shown schematically in the drawings using an exemplary embodiment. It shows:

plate 1, where they are designed as straight retaining bolts 3a, 4a, 5a, 6a are, at a certain, approximately the same height, laterally two horizontally opposite one another extending groove-shaped recesses 16 in such a way that bolt sections 1.8 bounded by guide and retaining lugs 17 are formed with mutually parallel walls. To this Bolt sections 18 can each have two U-shaped metal wedges 19 with incisions extending in their longitudinal direction 20 can be raised. The incisions 20, which terminate in a curve at the end, have a somewhat greater width than the width of the bolt sections 18..

The wedges 19 are arranged in pairs in such a way that they with their inclined, upper and lower Surface 21 or 22 lie on top of one another.

The counterpart to anchor plate 1 with the retaining bolts.3a, 4a, 5a, 6a form a base plate 10 on which, for example, a. Support post 11 is welded. In the footplate 10 · are Bores, but preferably elongated holes 12, attached, which are inserted over the retaining bolts 3a, 4a, 5a, 6a and with the wedges 19 can be firmly wedged.

The metal anchors 3b, 4b, 5b, 6b are inserted into the concrete 15 let in. The concrete surface 'can with the surface of the anchor plate 1 flush (Fig. 6). In an advantageous manner, however, the inventive a suitable device can be placed recessed in the concrete by means of formwork attached above the anchor plate, so that the upper edge of the retaining bolts 3a, 4a, 5a, 6a is flush with the upper edge of the finished concrete. Through this a free space for fastening the support post 11 is created when concreting. After attaching the Post 11 can then be filled with synthetic resin mortar and flush with the rest of the concrete. surface can be peeled off. This ensures that the fresh concrete surface is also used during manufacture can be removed by machine. The retaining bolts 3a, 4a, 5a, 6a protruding beyond the anchor plate 1 are sunk and do not interfere with this.

All individual and combination features disclosed in the description and / or the drawings are considered essential to the invention viewed.
