Description

The invention relates to a diving wall cap for floating diving walls according to the preamble of claim 1.

Floating baffle walls are known according to patent DE 35 03 407 and have a rolling circle in the edge area which can be adapted to the respective local installation conditions, which is a decisive disadvantage with regard to series production, because the edge geometry in connection with the abutment dimensions is separate for each individual project is to be calculated and drawn.

• a) Baugleiche Tauchwandkappen für variable Einbaulängen
• b) Umströmungssicherung mittels Dichtschürze
• c) Reduzierung der vertikalen Gleitreibung
• d) Verschiebemöglichkeit der Tauchwandkappe zur örtlichen Anpassung

Die Lösung dieser Aufgabe wird erfindungsgemäß dadurch erreicht, daß die Tauchwandkappen schwimmender Tauchwände mit einer polygonzugartigen Außenseite versehen werden, die sich zumindest einem Mindestrollkreisdurchmesser anpassen.The present invention is based on the object of improving the manufacturing and handling techniques in the sense of optimal series production, so that the great need for floating baffle walls for installation in relief systems, etc. can be done more cost-effectively. Further improvements result according to this invention in terms of:

• a) Identical baffle wall caps for variable installation lengths
• b) Flow protection using a sealing apron
• c) Reduction of vertical sliding friction
• d) Sliding wall cap can be moved for local adjustment

This object is achieved according to the invention in that the baffle caps of floating baffle walls are provided with a polygonal-like outside, which adapt to at least a minimum rolling circle diameter.

This design of the outside has the essential advantage that all larger rolling circles, i.e. floating baffles of different lengths, can be produced with one and the same baffle cap with the same hat profile and are therefore better suited for series production. To improve the guiding properties, the invention The baffle wall caps are equipped with roller bearings for side limitation or load transfer from the flow pressure. To compensate for errors on the building side, the baffle wall caps can be slidably arranged on a central web on the outside of the baffle wall and fixed with bolts. So that a circulation of floating materials in the area of the hat profile can be excluded, the arrangement of an elastic sealing apron on the outer sides of the floating diving wall is provided over the entire height of the diving wall, which in turn rests on the fold of the hat profile and which thus brings about the complete sealing.

An advantageous embodiment of the invention is the subject of claims 1 to 5 and is illustrated in more detail in the drawing of an embodiment.

Fig. 2

2 shows a sectional illustration of the baffle wall cap (8) and the hat-shaped guide profile (1) at the level of the center line (11) from FIG. 1.

In Fig. 1 the baffle cap (8) with the polygonal edge (3) can be seen in the view, it being made clear that a lateral displacement (17) of the baffle cap (8) and its fixing by means of bolts (20) in the area of Elongation adjustment (21) is made possible. Furthermore, the independent use of the baffle plate (8) is also shown in the drawing as an example for all larger rolling circles (5, 6, 7), the side-limiting roller bearing (2) with the rolling point (12) on the groove base (13) of the hat-shaped guide profile (1 ) rests.

The section 'A - A' is dealt with in the drawing in Fig. 2, the position of the baffle cap (8) with the possibility of guiding the roller bearings (2) within the hat-shaped guide profile (1), and the sealing by means of the elastic sealing apron (24) can be seen. It can also be seen that the baffle wall cap (8) can be locked by forming a groove (16) on the web (18) by means of lateral displacement (17) and fixing by means of bolts (20).

Claims (5)

1. Slip-on guide cap for floating barrage moving on roller bearings (2) fitted into a hat-shaped guide profile (1), one important characteristic feature being the polygonal external edge (3) adjusted to a minimum rolling circle (5) at all corners (4). With all larger rolling circles (6,7), this permits the use of a guide cap of identical design (8) in accordance with a prescribed barrage height (9).
   The second characteristic feature is the rolling point (12) of a side control roller bearing (2) at the intersection (10) of all rolling circles (5,6,7) and the centre line (11) of the barrage (23). Such side control roller bearing (2) touches the groove base (13) of the hat-shaped guide profile (1) on at least one side.
2. Slip-on guide cap as per Claim 1, the characteristic feature being the provision of additional roller bearings (2) on each barrage side, at least two of these being positioned on the side of the barrage (15) opposite the water pressure (14).
3. Slip-on guide cap as per either one of Claims 1 and 2, the characteristic feature being that the actual guide cap (8) has a groove runnning in a vertical direction (16) permitting a sideways movement (17) on the web (18) fixed to the lateral edge of the actual barrage (22).
4. Slip-on guide cap as per Claim 3, the characteristic feature being the possibility of lateral movement (17) by means of at least two screw-fixed bolts (20) and a corresponding long-hole adjustment (21) in the web (18).
5. Slip-on guide cap as per either one of Claims 1 to 4, the characteristic feature being the fact that, if required for an improved sealing on the lateral edge (22) of the floating barrage (23), a flexible sealing apron (24) is provided along the full height of the barrage (9), adjusting to the bevelled edge (25) of the hat-shaped profile (1), on the water pressure side.
