Description

Field of the invention

The invention relates to a dam for the protection of objects, and in particular a dam with a thin extruded profile.

State of the art

Flood protection walls are usually used to protect localities from flooding. Such flood barriers are usually up to 6 m high. However, such a flood protection must be provided by the authorities and requires considerable effort in the installation of flood defenses, which must extend over several 100 m or even kilometers, in part, in order to provide the appropriate flood protection for localities.

However, such flood barriers are not provided in all localities where only individual houses or limited areas of flood can be affected. For example, in a cellar entrance water can penetrate, which then flooding the corresponding basement and can damage the stored there items or technical equipment. For such property protection, the flood protection walls, which are used for flood protection of localities, but not suitable. The normal flood barriers are too big and too bulky and take quite a lot of effort to lay the appropriate foundations. In addition, individual persons can not quickly build the flood protection walls in case of need and dismantle again, since the individual dam beams are too large.

For the protection of the property there are therefore flood protection walls, which are a smaller version of the flood protection walls. For this object walls also foundations are laid and support beams mounted and attached between these support beams the dam beams of the water protection wall also usually. However, the construction and in particular dismantling of the flood protection walls is difficult because after use the water protection walls are often glued with mud, wet, slippery and filled with water, which is why the individual dam beams are difficult to solve from the support beams. One solution to this problem may be to mount handles to the dambars, such as by welding, but this significantly increases the cost of each dambar.

Presentation of the invention

The present invention therefore has the task of providing dam beams for an object protection wall, which are easy to dismantle and disassemble and are inexpensive to manufacture. This object is achieved by a dam beam according to claim 1.

An inventive object protection dam beam comprises a longitudinally extending, hollow extrudate having an upper portion, a lower portion, and two sidewalls connecting the upper portion to the lower portion, the lower portion having two support projections on both sides and the upper portion at least one side has a sealing groove which is provided for introducing a seal are placed on the at least one of the two support projections of an adjacent dam beam, wherein on the upper side a Hubnut is provided which has an undercut. Such a dam beam is easy to build as a water protection wall for the property protection and, above all, dismantle again.

The undercut is preferably inclined on the upper side and formed in particular rising towards the center. With such a tendency, a simple positive locking can be achieved, which prevents slippage of the lifting tool in the Hubnut.

The undercut of the Hubnut is preferably formed below the bottom of the sealing grooves. The arrangement of the undercut under the sealing groove of the dambar can be made even narrower, because the widest areas of the grooves are offset from one another. A narrower dambar is lighter and therefore cheaper and easier to handle.

At least one projection is provided on the upper side. The projection serves to press on / clamp the mounted dam beams and thus enables a better seal. The at least one projection is provided at the edge of the Hubnut. Here it is arranged in the most space-saving way.

In another aspect of the invention, an object barrier dam beam according to the present invention comprises a longitudinally extending, hollow extrudate having an upper portion, a lower portion, and two sidewalls connecting the upper portion to the lower portion, the lower portion being two on both sides Support projections and the upper portion has on at least one side a sealing groove, which is provided for introducing a seal is placed on the at least one of the two support projections of an adjacent Dammbalkens, wherein at least one projection for supporting a bracing device is provided on the upper side. By means of such a projection can be ensured that a sufficiently large force for the bracing of the dam beams and especially for the Sealing can be provided on the foundation and introduced into the water protection wall, without the dam bars are damaged.

The projection is preferably provided in the edge region and in particular as an extension of the Hubnut. This optimally utilizes the space on the dam beam to make it as narrow as possible.

At the bottom of the dam beam, a receptacle for a foot gasket may be provided.

Furthermore, both sides can be connected by a central strut, which increases the strength of the dam beam.

Description of the Preferred Embodiments

When used below, the terms "lengthwise,""width," and "height" refer to a dambar unless explicitly described otherwise. In FIG. 1 For example, the height refers to a direction from bottom to top, the "width" to a direction from left to right, and the "length" or "longitudinal direction" refers to the direction in the drawing plane (or the opposite direction).

FIG. 1 shows a dambar 10 in cross section. The dam beam 10 has a thin-walled extruded profile with an outer wall thickness of 1mm - 5mm, preferably 1.5mm - 3mm. The two side walls 12 may be with one or more Reinforcement struts 13 may be connected, which once again increase the stability of the dam beam 10.

Such dam bars 10 are stored in use laterally by support beams 40, as for example in the Figures 5-7 are shown. A support beam 40 is essentially a longitudinally extending beam with a receptacle 44 for the dam bars 10. The receptacle 44 is formed substantially by the side walls 42 and the rear wall 41 of the support beam 40. In the receptacle 44 preferably longitudinal grooves 46 are provided on the inner sides of the side walls 42, in which a seal can be introduced, which seals the connection point between dam beams 10 and support bar 40. In a preferred embodiment, the support bar 40 has at its upper region on the inner sides of the side walls a recess 48, which is in particular formed perpendicular to the longitudinal extent, as in FIG. 4 can be seen. This recess 48 serves as a bearing point of a biasing device 50, which will be described below.

In the upper region 17 of the dam beam 10, at least one sealing groove 11 is provided. In the preferred embodiment sealing grooves 11 are provided on both sides, which improves the seal between two dam bars 10 and thus the water protection wall. The seal groove 11 may be formed as a simple rectangular groove, but may also include an undercut to accommodate and hold a correspondingly shaped seal 15.

At the upper portion 17 of the dam beam 10, a Hubnut 18 is also provided. This extends in particular centrally in the upper region 17 downwards and has an undercut 19. The undercut 19 serves as an engaging portion for a in FIG. 2 illustrated and described below lifting tool 30 and may generally be configured arbitrarily. In a preferred embodiment, however, the undercut is inclined towards the groove opening and, in particular, it is rising, since this simplifies the production of the lifting tool 30. Other configurations may have a descending slope for slot opening to allow a hook-shaped tool to securely grip the undercut 19. The undercut 19 is preferably formed below the sealing grooves, so that the dambar 10 can be made as narrow as possible.

Furthermore, the dam bar 10 has at least one projection 16 in the upper region 17. This projection 16 serves as a support for a clamping tool 50, as shown in the FIGS. 6 and 7 is shown. The projection 16 is formed as a wall and may extend over the entire length of the dam beam. Preferably, two projections 16 are provided, which in particular are symmetrical (with respect to a vertical center axis of the Cut in FIG. 1 ) are arranged on the top of the dam beam 10. Preferably, the projections 16 are provided on the groove edge, so to speak as an extension of the groove 18 on the seals 15 addition. The projections 16 may be provided at the upper end with a support surface which may be formed, for example, by folding the projection 16 by 90 °. It is only important that the at least one projection 16 can be received in the below described receptacle for the foot seal at the lower portion 14 of the dam beam 10, so that the dam bars can be placed on identical other dam bars 10 and stacked to the water protection wall.

In the lower region 14, the dam beam 10 has a receptacle for a foot gasket 25. The receptacle is formed by two laterally arranged foot projections 22, which can then receive the foot gasket 25 between them. Preferably, the two projections 2 at the lower end to a thickening 23, which facilitates the holding of the bottom seal 25. The thickening 23 is directed inwards and can thus pinch the base gasket 25 in the receptacle, in particular if the foot gasket 25 is designed to bulge outwardly, as shown in FIG FIG. 3 is shown. The foot seal 25 has an upper portion 26, which is preferably shaped according to the reception of the dam beam, and a lower portion 27 which is formed substantially rectangular. Preferably, the foot seal 25 is formed in two parts, for example, by gluing the upper portion 26 with the lower portion 27. Thus, different materials for the foot seal 25 can be used. The lower portion 27 of the base gasket is designed such that unevennesses can be compensated for the foundation.

To brace the stacked dam beams, a bracing 50 is provided. The bracing device 50 has a holder 52, by means of which the bracing device 50 can be fastened to the support beam. For this purpose, the holder is designed such that it can be inserted into the recess 48 of the support beam 40. Preferably, the bracket 52 is a metal plate that can be easily slid into the recess 48. In the holder 52, a threaded pin 54 is provided, which can move by turning up and down. At the lower end, the threaded pin on a pressure plate 56 which can rotate relative to the threaded pin. This pressure plate 56 is then moved by screwing the threaded pin 54 on the projections 16 and presses on this on the uppermost dambar 10 to clamp the water protection wall.

The lifting tool 30 for lifting the dam bars during disassembly of the water protection wall comprises a handle, a plug-in rod and a lifting armature. The plug-in rod and the lifting armature must be narrow enough to fit in the lifting groove to be pushed into it. The lifting armature is therefore designed to be longer in one extension direction than in the other. In FIG. 2 the lifting armature is rotated to the lifting position, so that its upper side abuts against the upper side of the undercut of the Hubnut and the dam bar can be raised thereby. The flattened on the diameter of the plug rod side of the lifting armature can be seen in the front view.

In the in FIG. 2 As shown, the lifting tool 30 is formed in a simple embodiment. The handle 32 is formed as a simple cylinder of, for example, wood or metal and has a kind of screw as a push rod 34, the conical head 36 has been flattened on two opposite sides, for example by grinding the sides. However, other embodiments are possible, for example, a hook-shaped lifting armature or a flat plate.

When installing an object protection wall according to the invention, the support beams 40 are usually anchored to a wall, for example by a screw connection. Between the support beam and the wall and under the support beam any leaks can be sealed with a resin, so that no water can leak under or behind the support bar 40. Ideally, there is also a flat foundation under the dam beams to be laid. By the bottom seal 25 can be waived, however, since this can compensate for any bumps. The bottom seal 25 is anchored in the lowermost dam beam 10 with its upper portion 26, the dam bar 10 is used with bottom seal 25 in the recording of the support beams and pushed onto the foundation or the ground. Subsequently, the further dam bars 10 are inserted into the support struts 40 and pushed onto the respective lower dam bars. Subsequently, the uppermost dam beam 10 is then clamped with the aid of the tensioning device 50.

To disassemble the water protection wall, the bracing device 50 is released and the dam beams 10 lifted out. To lift out the lifting armature 26 and the insertion rod 34 is inserted and rotated in the Hubnut 18, in particular by 90 °. As a result, the lifting armature 36 rotates under the undercut 19 of the lifting groove 18, engages the upper side thereof and transmits the lifting force to the dam bar 10, which then slides upwards from the receiving recesses of the lateral support bar.
