The invention relates to a connection between a precast reinforced concrete part and the head of a sheet pile wall, the reinforcement of the precast reinforced concrete part can be connected to the head of the sheet pile wall

From DE-GM 19 51086 is a kit for Construction of walls for river construction purposes from prefabricated parts similar to the well-known building method »Berliner Shoring «known The kit consists of individual steel or reinforced concrete girders with an I-shaped cross-section that can be driven in at a distance from one another wipe the flanges of these girders from prefabricated reinforced concrete slabs that can be pushed in from above. Here, the reinforced concrete slabs are bonded via the Support only in a horizontal direction and ■ light in a vertical direction.

The magazine »Die Bautechnik«, 1973, issue 12, page 412 shows reinforced concrete spars on sheet piling, with this known spar training the spar with each individual connecting steels in the spar 4 sheet pile wall welded but this spar design is not a rigid vertical connection between Forms spar and sheet pile wall, which is not necessary here, since the task of such spars is only the formal covering of the sheet pile heads. This is also lost in the last paragraph Point 11.6 of this reference points out, where it says: “The precast concrete spars mentioned are not for Suitable for the transmission of large perpendicular forces. The same applies to the inclusion of horizontal ones Forces, since such prefabricated parts are generally carried out relatively easily ”.

The reference "Die Stahlspundwand Hoesch", 6, improved edition 1965, page 96, Fig. 88 shows one I-shaped spar chord made of steel for inclined pile anchoring, the upper open part of which is filled with concrete is where the concrete filling has no static significance but has only been chosen from a purely structural point of view Concrete filling also welded on cover plates, asphalt concrete filling or floor filling use Find.

Furthermore, a connection between a precast reinforced concrete part and a sheet pile head is known from which the precast reinforced concrete part is connected to the sheet pile head via an in-situ concrete seal In-situ concrete seal, which requires complex formwork, reinforcement and concreting work on the construction site, however, the advantages of sheet piling and prefabricated reinforced concrete construction, which are modern prefabricated construction methods, are partially lost.

The invention is therefore based on the object of providing a rigid connection in the vertical direction between a horizontally and vertically large-area precast reinforced concrete element and a sheet pile head create that are largely factory-made and without costly formwork, reinforcement and concreting work can be produced on site

According to the invention, the object is achieved in such a way that the precast reinforced concrete part with the foot side on the outside Concrete and welded to the reinforcement steel plate is provided with a on the head the sheet pile wall rigidly arranged section steel can be connected. The reinforcement in the Precast reinforced concrete part welded on steel plates with the profile steel. To even this Avoiding welding work on the construction site is the base of the precast reinforced concrete part with the profile steel screwed.

The profile steel is expediently a channel steel or double-T-steel, one or both of the upward-facing flanges of the channel-steel or double-T-steel also being inclined inwards in order to e.g. B. Tolerances of the To be able to compensate for the width of the foot of the precast reinforced concrete part. To / B. the insertion of the precast reinforced concrete element into the one on the top of the sheet pile wall To facilitate profile steel and a possibility of aligning the precast reinforced concrete part in the vertical To create, it is advantageous that the steel plates concreted in the precast reinforced concrete part are arranged in a wedge shape.

In order to create a further possibility for aligning the precast reinforced concrete part in the vertical, is the profile steel is a concave curved sheet, with only one concreted in the precast reinforced concrete part corresponding convex steel plate is provided.

The advantages of the connection between a precast reinforced concrete part and the head of a sheet pile wall according to the invention are particularly in the extensive factory machining and production to see, which means that apart from welding or screwing work, no further work is necessary on the construction site are. In addition, the advantages of modern prefabricated construction are retained.

In the drawing, the connection according to the invention is explained in more detail with the aid of exemplary embodiments explained. It shows

Fi g. 1 a connection in section,
F i g. 2 another connection in section,
F i g. 3 another connection in section,
F i g. 4 another connection in section and
F i g. 5 a further connection in section
As can be seen from FIGS. 1 to 4, the connection between a precast reinforced concrete part 1 and the head of a sheet pile wall 2 consists of a section steel arranged on the head of the sheet pile wall 2, e.g. B. a U-steel 3 or double T-steel 4 (Fig. 1, right side), which is open at the top and welded to the head of the sheet pile wall 2, and two on the outside of the foot in the upwardly open section steel 3, 4 inserted precast reinforced concrete part 1 concreted in and welded to the reinforcement 5 in the precast reinforced concrete part 1, which are welded to the profile 3, 4 (Fig. 1, 3 and 4) or connected via screw bolts 7 (Fig. 2) are, the screw bolts 7 guided horizontally through the flanges 8 and precast reinforced concrete part 1 with the steel plates 6.

In order to be able to compensate for width tolerances of the foot of the precast reinforced concrete part 1, one can evenly pointing flange 8 of the channel steel 3 or double-T steel 4 be inclined inward (FIG. 3).

In an embodiment not shown, can both flanges also be inclined inwards.

To z. B. threading the foot of the precast reinforced concrete part 1 into the channel steel 3 and a possibility for aligning the precast reinforced concrete part 1

To create in the vertical, the steel plates 6 are arranged in a wedge shape (Fig. 4).

A particular embodiment is shown in FIG. 5. To get another way to align the To create reinforced concrete prefabricated part 1 in the vertical is that which is welded onto the head of the sheet pile wall 2 Profile steel a concave curved sheet 9, which is with a correspondingly convex curved steel plate 10 in the foot of the precast reinforced concrete part 1 is welded, the Steel plate 10 is also welded to the reinforcement 5 in the precast reinforced concrete part 1

To produce a connection according to the invention between the precast reinforced concrete part 1 and the head of the sheet pile wall 2, the sheet pile wall 2 is pulled together in the factory to form panels several meters wide and provided with the selected section steel 3, 4 or 9. These finished sheet piling panels are then used rammed into the construction site as a large area element or vibrated in. Then the precast reinforced concrete part 1, which is also factory-fitted with Hen steel plates 6, 10 is made, used in the profile steel and only still connected to this by welding or screw bolts 7.

The seal of the connection is made through the continuous weld seams guaranteed or with the screw connection by not shown, pressed-in, permanently plastic putty or a similar material.
