Device for closing an opening

Abstract

A device (11) for use in closing a leadthrough (2) in a constructional element for conduits (3) includes a frame member (16) enclosing a leadthrough space (17), and a plurality of strip-shaped sealing elements (18) arranged in the leadthrough space (17) displaceably relative to each other, with the frame member (16) at least one of frame section (19) having an opening (20) through which the strip-shaped sealing elements (18) are at least partially extendable out of the leadthrough space (12).

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a device for closing a leadthrough in a constructional element, in particular, for closing a wall leadtrough, for conduits such as cables, pipes, channels, and the like, and including a frame member enclosing a leadthrough space, and a plurality of strip-shaped sealing elements arranged in the leadthrough space displaceably relative to each other. [0003] 2. Description of the Prior Art [0004] In order to be able to pass conduits through a constructional element such as a wall or ceiling of a building, leadthroughs are provided in the constructional elements. In order to prevent spread of fire in the building in case of a fire, the leadthroughs should be closed with suitable elements. In addition to the prevention of the spread of fire, also, the spread of produced, in case of a fire, flue gases should be prevented. [0005] Suitable elements for closing leadthroughs are, i.e., compress...

Benefits of technology

[0012] A plurality of strip-shaped sealing elements close the leadthrough space, which is enclosed by the frame member, in a fence-like manner. The strip-shaped sealing elements are tightly arranged next to each other, forming a substantially closed wall. Advantageously, all of the strip-shaped sealing elements are arranged parallel to each other. In addition, to a flue gasproofness, the inventive device also insures damping of an airborne noise. The strip-shaped sealing elements are formed, advantageously, of a close-cellular material, e.g., of a close-cellular foam material, are arranged tightly next to each other, and can be easily displaced relative to each other.

[0013] As a result of such arrangement, the strip-shaped sealing elements can be easily conformed to the profile of the pass-through conduits. Through the opening in at least one frame section of the frame member, each separate strip-shaped s...

Problems solved by technology

A drawback of all of the conventional solutions consists in that with a temporary closing of the leadthroughs, during removal of conduits or a subsequent insertion of additional conduits, the inserted sealing elements need first to be removed, if necessary, using suitable tools, and then again need to be inserted in the leadthroughs.

These additional works are time-consuming and in most cases costs-intensive.

The drawback of the device consists in that with large differences in the conduit dimensions, e.g., in conduit diameters with bundlings of several conduits, the device cannot insur...
