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).

Claims

1. A device (11) for use in closing a leadthrough (2) in a constructional element for conduits (3), comprising 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, the frame member (16) having at least one 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 (17).

2. A device according to claim 1, comprising at least one locking device (31) provided on the frame member (16) for securing the strip-shaped sealing elements (18).

3. A device according to claim 1, wherein the strip-shaped sealing elements (18) are formed of an actively fireproofing material.

4. A device according to claim 1, wherein the frame member (16) has a frame section (23) removably attached thereto and located opposite the at least one frame section (19).

5. A device according to claim 1, wherein the frame member (16) has attachment elements (36) for securing the frame member (16) to the constructional element.

6. An arrangement (1) for closing a leadthrough (2) for conduits (3) in a constructional element, comprising two closing devices (11) each having 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, the frame member (16) having at least one 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 (17);

and a box-shaped section (12) for connecting the two devices (11) with each other.
