DESCRIPTION

Device for sealing building openings

The invention relates to a device for rapid sealing of openings on buildings, wherein a planar, the opening associated Elemen ,, and a seal are provided.

It is sometimes necessary to seal the inside of buildings against unwanted media (eg gas, water). Often this has to happen very quickly, for example during flood disasters.

It is known to secure openings on buildings in such a way that sacks filled with sand are placed in front of them. This type of sealing is completely insufficient.

Furthermore, it is common to fence the building openings. This method is cumbersome, expensive and it must be bricked up again and again and then the masonry be broken out.

The invention has for its object to provide a fast and with simple means to realisiyrende sealing of Gebaudeoffnungen.

This object is achieved in a device of the initially described Ar'c characterized in that the planar element is designed as a loose, adjustable in the opening frame with a filling and the frame is provided at the outer edge with inflatable seals.

In the opening 6 of a wall 3, for example, a profiled sheet metal frame 7 is used. The sheet-metal frame is expediently provided in the printing direction D (FIG. 1) with the filling 1, which is formed convexly (cambered) in order to ensure the necessary stability even at relatively high pressures. At the outer edge of the sheet metal frame 7 is one or more

According to a further embodiment of the invention, it is provided that the runner is formed as a profiled sheet metal frame.

According to the invention, it is also possible for the filling to be provided as a surface which is convexly formed in the printing direction.

The advantages achieved by the invention are, in particular ^ that building openings can be sealed with an effortless handles and the means for sealing can be used over and over again_f

An embodiment of the invention is in the |

inflatable seals 2, depending on the load of the hedge (high water). The inflation of the seals 2 via valves 5,

If, for example, flooding threatens to penetrate a building, the frame 7 that fits the opening 6 is placed in it and the gasket or seals 2 are blown. If the sealing of the opening 6 is no longer required, the air is released from the seals 6, the frame 7 with the seals 2 is removed and stored at a suitable location in order to be reused in due course.

should it be necessary, the corners of the opening C may be equipped with wedge-like sealing elements 4 in order to • achieve better nestling of the seal 2 in the corners.

It is also conceivable, especially for new buildings, doors and windows (basement windows) to provide with inflatable seals 2, which are inflated if necessary.
