Description

The invention relates to a shut-off device for retaining floods or the like. With bar-shaped shut-off elements which can be arranged in a horizontal position one above the other and which engage with their ends in approximately U-shaped receptacles, with the shut-off element between the contact surfaces and within the receptacles Seals are provided.

A shut-off device of the type mentioned at the outset is known from DE-A-34 20 405 with a plurality of shut-off elements lying one above the other to form a vertical bulkhead. The individual shut-off elements are connected to one another in the manner of a tongue and groove connection, a sealing strip being arranged on the underside of each shut-off element. The shut-off elements within the receptacles are sealed by means of vertical sealing tapes which are attached to the legs of the U-shaped receptacle opposite the water side. On the bottom side of the shut-off device, a concrete strip foundation is provided, in which quivers are provided for inserting the receptacles. On the upper and lower sides of the individual beams there are several spaced-apart elongated through-openings for clamping bolts with transverse pins arranged at their free ends, which are inserted into the corresponding opening in the strip foundation and can be fixed after turning in the manner of a bayonet catch. By tightening wing nuts on the ends of the clamping bolts projecting upward from the shut-off elements, the shut-off elements are pressed against one another and the lowermost shut-off element is pressed against the strip foundation. However, this definition of the shut-off elements by means of clamping bolts is associated with a very high expenditure of time and work, which is often not available in the event of a disaster. Another disadvantage of Known shut-off device is the sealing of the ends of the shut-off element in the receptacles, which is to be done in that the beams are pressed by the water pressure against the sealing tapes running in the vertical direction on one leg of the U-shaped receptacles. Due to the gradually increasing dynamic pressure of the floods, at least initially, water can be expected to flow into the space to be sealed off.

Furthermore, from DE-A-38 33 561 a shut-off device with a shut-off element that can be inserted into lateral receptacles is already known. For the locking a locking mechanism is provided, by means of which a vertical force is exerted on the shut-off element, whereby at the same time sealing the barrier against the floor and against the lateral sealing surfaces arranged on the receptacles is achieved. In the extinguishing water barrier known from DE-A-38 42 555, a movable bolt is finally provided for locking the shut-off elements in the sealing position, which engages in an engagement opening in the respective receptacle and thereby a vertically downward and at the same time a lateral sealing force on the shut-off element exercises. However, these two known barriers are primarily intended for fire-fighting water retention in buildings and also cannot be stacked on top of one another for different accumulation heights.

The object of the invention is to develop a shut-off device for flood protection or the like which can be used in a mobile manner and is simple, safe and quick to assemble.

To achieve the object, it is provided according to the invention that extensions extending in the longitudinal direction are arranged on the end faces of the shut-off elements, wherein in the receptacles for the shut-off elements cooperating with these extensions locking elements can be used, which are supported in the locking position in the receptacles and exert an at least vertically downward pressure on the shut-off elements.

According to a first particular embodiment of the invention, it is provided that the locking elements and the extensions on the shut-off elements for laterally displacing the shut-off elements against the seals of the receptacles i. w. are positively connected to each other. As a result, both a vertically downward sealing force for pressing the shut-off elements against one another and the lowermost shut-off element against the floor and a lateral sealing force component against the vertically extending sealing strips in the receptacles are achieved by means of the locking elements.

According to the invention, the locking elements can be designed as wedge elements, which can be arranged on the extensions of the shut-off elements and can be driven in the locking position by exerting at least one vertically downward contact pressure on the shut-off elements in counter bearings on the receptacles. Such wedge elements can be driven in effortlessly, for example with a sledgehammer, without the need for special tools. The wedge elements can also be brought to the respective place of use in a simple manner and can be carried by the fitters in sufficient numbers, which is also advantageous in the case of flood protection devices which have to be set up quickly in the event of danger.

The generation of a vertically downward and lateral sealing force can be achieved with such wedge elements in that the counter bearing side stops for a have lateral displacement of the locking elements or the shut-off elements connected to them in a form-fitting manner against the seal in the receptacles.

To form a positive connection between the locking element and shut-off element, it is provided according to the invention that at least the extensions of the shut-off elements on their upper side have a longitudinal profile and - the locking elements on their underside have a corresponding counter-profile, which, for example, in the manner of a groove and Spring system or can be achieved by multiple webs and grooves.

The insertion of the locking or wedge elements can be improved according to a proposal of the invention in that the shut-off elements with the extensions have a continuous profile, the profile of the extension being offset in height with respect to the profile of the shut-off element. During assembly, the wedge element is first placed on the top of the shut-off element and pushed outwards into the receptacles or the counter-stops. The wedge element settles down when struck into the counter-stops of the receptacles, so that an unwanted release from the locking position is prevented.

According to the invention, the locking elements can have a recess on their rear end side in the locking position for engaging a tool in order to release and remove the locking elements from the locking position.

The locking elements or wedge elements are preferably formed symmetrically in the longitudinal direction, so that they can be used both in the left and in the right receptacle.

The manufacture of the counterbearing in the receptacles can be realized in a structurally simple manner according to a proposal of the invention in that in the opposite corner areas of the U-shaped receptacles there are angular profiles with recesses for the locking elements which form a staggered height arrangement and the side stops as in the corner area of the angle profiles arranged flat strips are formed.

These receptacles are preferably made of metal, just as the shut-off elements themselves can be made of metal, possibly also of light metal.

The side stops for the locking elements are preferably arranged on the water side of the receptacles, so that the back pressure which is built up additionally achieves a lateral contact pressure of the shut-off elements against the sealing strips arranged on the opposite side of the receptacle.

It is also within the scope of the invention that the locking element is designed as an eccentric bolt, which can be inserted into the legs of the U-shaped receptacle and, with a rotary movement, acts with its outer jacket on the top of the respective extension of the shut-off element while exerting a vertical contact pressure.

The eccentric bolt can have a slope that is inclined with respect to the vertical plane, which engages on one side surface of the extension of the shut-off element and, when the eccentric bolt rotates, exerts a lateral contact pressure on the shut-off element in the direction of the sealing strips arranged on one leg of the receptacles. This can be done by inserting eccentric bolts into the receptacles Only one rotational movement, both a vertical and a lateral contact pressure on the shut-off elements for a bottom and side seal can be achieved.

The slope of the eccentric bolt is advantageously designed as an approximately spirally wound contact surface, possibly with a run-on slope. Likewise, the spiral contact surface, preferably after half a thread, can merge into a contact surface parallel to the side surface of the extension and flattening can also be provided, so that turning the eccentric bolt by a little more than 180 ° achieves a securing position and for that Turning back the eccentric bolt a certain contact resistance must be overcome.

In order to prevent water from penetrating through the holes in the eccentric bolt, it can be mounted with a seal on the receptacle.

With regard to simple handling, it is provided that the eccentric bolt has an attachment for a tool at one end.

Finally, it is within the scope of the invention that cams, preferably semicircular, are provided on the water-side leg of the receptacles as an insertion aid and for aligning at least the lowermost shut-off element.

Further objectives, advantages, features and possible uses of the present invention result from the following description of two exemplary embodiments with reference to the drawings. All of the features described and / or depicted form the subject matter of the present invention, either individually or in any meaningful combination regardless of their summary in the claims or their relationship.

The flood barrier according to the figures has shut-off elements 2 which can be stacked one above the other and which are held with their end-side longitudinal sections in supports 1 in the form of supports. The receptacles 1 are U-shaped with a sealing strip 4 arranged on each leg, against which the shut-off element or elements 2 are pressed in the sealing position with a section of the side wall. The shut-off elements each have seals 8 on the bottom.

The shut-off elements furthermore have a profiling 9 on their top and bottom sides, which is designed in the manner of a tongue and groove system in order to prevent the shut-off elements 2 from shifting in the stacked position in the transverse direction. Arranged on the leg of the receptacle 1 opposite the sealing strip 4 is an approximately semicircular cam 10 which automatically aligns the lowermost shut-off element 2 within the receptacles 1, in particular with respect to the sealing strip 4. The semicircular design of the cam 10 also causes one Insertion aid for the bottom shut-off element 2 when inserted into the receptacles 1. The profiling 9 of the shut-off elements 2 also ensures that the further shut-off elements 2 are aligned.

At the front ends of the shut-off elements 2 there are extensions 5, which are attached to the end caps that close the hollow profile of the shut-off elements 2. The caps 11 can be provided with openings (not shown) in order to allow flooding of the shut-off elements 2 designed as a hollow profile and thus to prevent buoyancy of the shut-off elements 2.

As can be seen from FIGS. 3, 5 to 7, the extension 5 has on its upper side a profile 12 corresponding to the profile 9 of the shut-off element 2, the height of which is somewhat offset from the profile 9 on the shut-off element 2, as is particularly the case in FIG 5 can be seen.

The locking elements 2 are locked by means of wedge elements 3, which on their underside have a contour adapted to the profile 9 of the locking element 2 or the profile 12 on the extension 5. In this way, a positive connection between the shut-off element 2 and the wedge element 3 is achieved. After inserting the shut-off element 2 into the receptacles 1, a wedge element 3 is placed on the profile 9 of the shut-off element 2 and moved outward in the direction of the arrow according to FIG. 5 and wedged in a counter bearing 16 adapted to the wedge shape. This counter bearing 16, as can be seen in particular from FIGS. 3, 5 and 6, is formed by two angle profiles 6 arranged in the corner region of the receptacle 1, which have a slope 13 corresponding to the slope 14 of the wedge element 3. As a result, a contact pressure on the shut-off element 2 becomes perpendicular in the direction generated downwards. Furthermore, a side stop 7 is arranged on the one angle profile 6, on which the wedge element 3 comes into contact with its lateral contact surface 15. As a result, a lateral force is simultaneously exerted on the shut-off element 2 in the direction of the sealing strip 4 and, due to the positive connection, also on the shut-off element 2.

As already mentioned above, the profile 12 on the extension 5 is offset in height relative to the profile 9 on the top of the shut-off element 2, so that the wedge element 3 settles down on the corresponding receptacle 1 when it is driven into the counter-bearing 16 and is therefore an unwanted one Loosening from its wedge position is prevented.

The wedge elements 3 are preferably made of plastic, whereby a favorable frictional resistance is achieved when driving. Another advantage is that the wedge elements 3 are symmetrical with respect to their contact or wedge surfaces 14, 15, so that they can be used both for the left and for the right receptacle 1.

The wedge elements 3 can be released from the receptacles 1, for example, by providing a bore in the back of the wedge elements 3, into which a key can be inserted in order to pull the wedge elements out of their securing position by lever action.

The locking elements 2 can be secured individually, in that each locking element 2 is secured with lateral wedge elements 3, and further locking elements 2 can be stacked or secured in turn. Of course, it is also possible to first stack a plurality of shut-off elements 2 one above the other and secure the uppermost shut-off element 2 with wedge elements 3.

The shut-off elements 2 are symmetrical, so that during assembly there is no need to pay attention to an assignment of the respective end to the corresponding receptacle 1.

The receptacles 1 can be mirror-symmetrical, in the form of a double U, so that a continuous wall can be formed as flood protection. The supports or receptacles 1 can also be designed to be removable in order to be anchored in a base plate if necessary.

The shut-off device according to FIGS. 9 to 14 differs from that according to FIGS. 1 to 8 in that, instead of wedge elements, eccentric bolts 18 are inserted into the receptacles 1 as locking elements. Otherwise, the two embodiments are i. w. equal. The same reference numerals have therefore been used for identical components, so that a detailed description can be dispensed with in this respect.

The eccentric bolts 18 provided for transferring the shut-off elements 2 into their sealing position are mounted in bores in the legs of the receptacles 1. The eccentric bolts 18 each have a bevel 21 which extends in the circumferential direction and which, starting with a bevel 21, has an approximately spiral-shaped contact surface 20 and then merges into a straight stop surface 23. As can be seen in particular from FIGS. 10 and 11, the eccentric pin 18 has a flattened portion 25, which has the function of a stop.

The eccentric pin 18 or the bevel 21 with a spiral contact surface 20 and a straight section 23 and the flattening 25 interact with the extension 5 of the shut-off element 2 protruding into the receptacles 1. The extension 5 also forms a closure cap, which the end faces of the Completes the profile of the shut-off element 2. In addition, openings can be provided in the closure caps (not shown), which allow flooding of the shut-off element 2 designed as a hollow body profile.

Figures 10, 11 and 12 show the shut-off element 2 in the unlocked state, while the remaining figures show the shut-off element 2 in the locked state. When installing the shut-off element 2 is inserted into the receptacles 1. Then the eccentric bolts 18 are inserted into the holes on the legs of the receptacles 1. The eccentric bolts 18 have a flattened portion 26, as a result of which a certain clearance is achieved between the eccentric bolts 18 and the extension 5 in order to facilitate the insertion of the eccentric bolts 18 through the bores in the legs. By turning the eccentric pin 18, in the exemplary embodiment chosen here clockwise, the spiral contact surface 20 comes into contact with the lateral contact surface 22 of the extension 5. This causes the shut-off element or elements 2 to be pressed downwards and at the same time by the spiral section 20 to the side Pressing the shut-off element 2 against the sealing strip 4. When the eccentric bolt 18 is rotated further, its straight section 23 comes into contact with the contact surface 22 of the forest set 5 of the shut-off element 2, so that a rotation of preferably more than 180 ° reaches a secure position of the eccentric bolt 18 is that a certain contact resistance must be overcome for turning back the eccentric bolt 18.

The eccentric bolt 18 is rotated by means of a key tool (not shown), for example a square key, which can be plugged onto a square 24 at one free end of the eccentric bolt 18.

In order to prevent water, which flows towards the shut-off element 2 in the direction of the arrow according to FIG. 9, through the eccentric bolt 18, the eccentric bolt 18 is sealed off from the receptacle 1. In the embodiment selected here, a seal 27 in the form of an O-ring is inserted on the contact surface of the collar of the eccentric pin 18.

The number of shut-off elements 2 to be stacked depends on the expected accumulation height. Of course, it is also possible, however, to first insert and lock only the lowest or the lowest shut-off elements 2 in the receptacles 1, in order to then stack further shut-off elements 2 above them in the event of rising flooding.

The eccentric bolts 18 are all identical, so that they can be inserted without presorting.
