Description

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 a kit for 4 ^r> creating walls for Flußbauzwecke prefabricated Berlin wall "is similar to the familiar design" known. The kit consists of individual steel or reinforced concrete girders with an I-shaped cross-section that can be driven at a distance from one another and prefabricated reinforced concrete slabs that can be pushed in from above between the flanges of these girders. In this case, the reinforced concrete slabs are bonded exclusively in a horizontal direction and not in a vertical direction.

The magazine »Die Bautechnik«, 1973, issue 12, page 412 shows reinforced concrete spars on sheet piling, with this known spar design, the spar in each case with individual connecting steels in the spar the sheet pile wall is welded, but this spar formation is wi dung does not form a rigid vertical connection between the spar and sheet pile wall, which is also not the case here is necessary, since the task of such spars only the formal covering of the sheet pile heads is. This can also be found in the last paragraph under t> "> Point 11.6 of this reference, 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, whereby the concrete filling siatisch no meaning has, but has only been chosen on the basis of purely constructive criteria. It could instead of the Concrete filling also welded on cover plates, asphalt concrete filling or floor filling use Find.

Furthermore is a? Connection between a precast reinforced concrete part and a sheet pile head known at 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 largely at the factory and without time-consuming 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 plates 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 z. B. the insertion of the precast reinforced concrete part in the arranged on the sheet pile head 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

F i 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 shown in FIGS. i to 4 shows, there is the connection between a precast reinforced concrete part 1 and the head of a sheet pile wall 2 from a section steel arranged on the head of the sheet pile wall 2, z. B. a U-steel 3 or double-T-steel! 4 (Fig. 1, right-hand side), which is open at the top and welded to the head of the sheet pile wall 2, and two on the foot-side outside in the reinforced concrete prefabricated part 1 inserted into the open-top section steel 3, 4 and attached to the reinforcement 5 in Precast reinforced concrete part 1 welded on steel plates 6, which are welded to the profile 3, 4 (Fig. 1,3 and 4) or via screw bolts 7 (Fig. 2), the screw bolts 7 horizontally through the flanges 8 and reinforced concrete prefabricated part 1 with the Stahlpbtten 6 are performed.

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

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

To z. B. threading the foot of the precast reinforced concrete part 1 into the channel steel 3 to facilitate alignment of the precast reinforced concrete part 1 To create in the vertical, the steel plates 6 are arranged in a wedge shape (Fig. 4).

A special embodiment is shown in FIG. In order to create a further possibility for aligning the precast reinforced concrete part 1 in the vertical the welded on the head of the sheet pile wall 2 profile steel a concave curved sheet 9, which with a Correspondingly convex curved steel plate 10 is welded in the foot of the precast reinforced concrete part 1, the

ίο Steel plate 10 also to the reinforcement 5 in Precast reinforced concrete part 1 is welded on.

To produce a connection according to the invention between the precast reinforced concrete part 1 and the head the sheet pile wall 2 is the sheet pile wall 2 already in the factory

i> pulled together 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 or vibrated in on the construction site as a large surface element. Then the reinforced concrete

2i) tigteil 1, which is also factory-made with the steel plates 6, 10 is produced, inserted into the profile steel and only with this by welding or screw bolts 7 connected.

The seal of the connection is made by the

r> continuous welds guaranteed or in the case of the screw connection by not shown, pressed-in, permanently plastic putty or a similar material.
