Abstract:
Conduit through which at least one pipe or cable extends, wherein the conduit has an inner wall and is provided with a system for sealing in the conduit that is unoccupied by the at least one pipe or cable, wherein the system comprises: at least one rubber element for providing in the conduit a support-structure which is clamped-in between the inner wall and the at least one pipe or cable; and a sealant layer against the support-structure and for sealing off at least one end of the conduit between the inner wall and the at least one pipe or cable, wherein each rubber element is made of a fire-resistant vulcanized rubber of a thermally substantially non-expandable type, and wherein the sealant is made of a fire-resistant polymer which is vulcanizable at room temperature under exposure to humidity and which is also of the thermally substantially non-expandable type.
Abstract:
A multi-layered structure of at least a ceramic base-layer and a paint-based protective layer or a paste-based protective layer, the protective layer being non-intumescent, wherein the protective layer exhibits at atmospheric pressure during an increase in ambient temperature a drop in its thermal conductivity.
Abstract:
A system for holding in a conduit cables and/or ducts with different diameters, comprising a plurality of rubbery or rubber- like sleeves for inserting in such a conduit, the plurality of sleeves comprising a number of units of bonded sleeves which are oriented parallel to each other, wherein within each unit the sleeves have corresponding outer dimensions, and wherein at least one unit has a sleeve having an inner diameter which differs from an inner diameter of a sleeve of at least one other unit of the number of units, wherein the number of the units and the dimensions of the units are such that therewith a stack of units can be made, in the stack of units each sleeve is also oriented parallel to any of the other sleeves, the stack of units having a rectangular shape of which each side is in detail shaped by the presence of a number of the sleeves and of which each edge is in detail shaped by the presence of one, two or three of the sleeves.
Abstract:
A passive fire resistant system for filling a space or gap confined by construction elements, for resisting the spread of a nearby fire through the space or gap, wherein the system comprises: at least two first layers of a first, material which comprises a fire resistant elastomeric foam raving a closed cell structure; and at least one second layer of a second material sandwiched between two first layers, the second material comprising a polymer and each second layer having surfaces which, as an initial response to a rise in their temperature from room temperature, exhibit a transition into an adhesive, the first and second layers extending parallel to each other, the second material being stiffer than the first material.
Abstract:
A pipe transit system comprising a conduit (1) having an inner wall and at least one pipe (3) extending through the conduit in an axial direction thereof so that the conduit (1) has a pipe-part that is occupied by the at least one pipe, wherein the system further comprises a first and a second sealing device (I, II) inserted in the conduit (1) each for sealing between an inner wall of the conduit and the at least one pipe (3) so that the conduit also has a sealed-part, wherein in the sealed-part between the first and the second sealing device at least one third sealing device (III) for sealing between the inner wall of the conduit and the at least one pipe is positioned, each of the first, the second and the third sealing device being a separate entity and being unconnected to any of the other respective sealing devices.
Abstract:
A system for providing a sealed transit for a situation wherein one or a plurality of cables, pipes or ducts (2) extend through the transit, wherein the system comprises a frame (100) which is sealingly fixed or fixable into or onto an opening, wherein the frame (100) comprises one or a plurality of conduits (203) which are each suitable for receiving at least one of the plurality of cables, pipes or ducts (2) and for receiving an elaεtically deformable plus (4) for sealingly filling space between an inner circumferential wall of the conduits (203) and at least one of the plurality of cables, pipes or ducts (2), wherein the system further comprises at least one blocking element (37) for hindering in each conduit (203) movement of one end of a plug (4) which is inserted in that conduit (203).
Abstract:
A system for sealing a space between an inner wall of a tubular opening and at least one tube or duct at least partly received in the opening such that a longitudinal direction of the opening and a longitudinal direction of the at least one tube or duct are substantially parallel to each other, wherein the system comprises at least two segmental longitudinal parts for forming a sealing plug which can be received in said space, wherein the longitudinal parts are each provided with a number of outer ribs and a number of inner ribs, wherein the inner ribs are adjacent each other in the longitudinal direction.
Abstract:
A system for sealing a space (16) between an inner wall (6) of a tubular opening (7) and at least one tube (17) or duct at least partly received in the opening (7), wherein the system comprises at least two segmental longitudinal parts (1) for forming a sealing plug (5) which can be received in the said space (16), wherein the longitudinal parts (1) are each provided with an outside (2) provided with a number of outer ribs (3) for realizing, in use, contact surfaces (4) closed upon themselves between the sealing plug (5) and the inner wall (6) of the opening (7), and wherein, further, each of the longitudinal parts (1) is provided with an outer collar (9) intended to be placed against an outer edge of the opening (7) in use, and wherein, further, the outer ribs (3) each substantially have the shape of a sawtooth (11) with rising surface (12).
Abstract:
A bushing arrangement for sealing passage of a cable, a pipe, a conduit or the like through an opening in a wall, which bushing arrangement comprises at least one seal arranged in the opening in the operative condition, which seal is at least substantially made of an elastic, fire resistant material with a base of a cross-linkable polymer and an expandable agent in a quantity and composition such that the seal will expand in case of a fire, in such a manner that the opening on the wall will be sealed medium-tight, a special feature being the fact that the material of the seal has a foam structure comprising closed cells.
Abstract:
A multi-layered structure of at least a base-layer comprising glass fibers and a paint-based protective layer or a paste-based protective layer, the protective layer being non-intumescent, wherein the protective layer exhibits at atmospheric pressure during an increase in ambient temperature, a drop in its thermal conductivity.
