Abstract

Apparatus for fire-sealing of a lead-through for at least one cable through a building component (1) build on frame-work, said apparatus (10) comprising an inner pipe (6) filled with a precompressed elastical fire-resistant foam material (7) and an outer pipe (5) surrounding the inner pipe (6). The apparatus (10) is mounted into a hole being made through the building component (1) and the two pipes (5 and 6) are connected to an outer surface (2, 3) of the building component each. This is rendered possible by the fact that between the pipes (5, 6) there is a gap (12) admitting the movement relative each other of the pipes (5, 6). The gap (12) is sealed by the fact that the foam material filling of the inner pipe with one part (8) reaches into the outer pipe (5) and presses against its inner surface.

Description

A FIRE-SEALED LEAD-THROUGH FOR FRAMED BUILDING COMPONENTS.
TECHNICAL FIELD
The invention relates to an apparatus for fire-sealing of a lead-through for at least one cable or wire through a building component consisting of a framework having arranged on each side of it boards of a fireproof material, preferably pluutβr, a.ihi αppnru..ιιu cπmpriuintj nn Iπnor pipu, ..ornplotoly nr partl y fille with elastic fire-resistant foam material precompressed transversely to the longitudinal direction of the pipe, and an outer pipe partly surrounding the inner pipe and being arranged displaceable relatively to the inner pipe, the pipes, in the mounted position of the apparatus in a hole being made through the building component, being intended to be connected with their relatively to the apparatus outer end parts to an outer surface each of the building component.
BACKGROUND ART
Several methods are developped for fire-sealing of lead-throughs for cables and/or wires through building components. Most of these methods have in common that they are preferably intended for walls of concrete. Usually these methods require a carefully planning of the running of the cable and/or the wire, as these methods mean that complete lead-throughs or mounting frames for such are moulded onto the building components. In the cases when complete lead-throughs will be used for moulding these are preferably made of a corrugated pipe covering of plastics which is filled with an elastic fire-resistant foam material. By means of a special tool cables and/or wires are run through the foam for example according to the method which is described in the S wedish patent No 412 795.
According to another method mounting frames are moulded into the building components as mentioned above. After the fact that cables and/or wires have been run through the space in a frame this is filled with premanufactured fire- resistant pass pieces or with a fire-protective substance.
Also methods to achieve fire-proof lead-throughs in already existing moulded building components have been developped. In the Swedish patent application No 426 122 a method and an apparatus is described to place, in a hole being made later in a building component, an elastic body of a fire-resistant foam material, said body having a considerably bigger diameter than the hole. According to the patent in question the body is compressed in the tool when being inserted in the hole and then keeps in place its compression transversely to the longitudinal direction of the hole, said compression being a condition for the intended functioning of the lead-through. Due to the high costs of the fire- resistant foam material the body generally does not fill the whole length of the hole but the length of the body is adjusted to the fire class of the wall in question.
The fact that light building technics is applied more and more and that fire classed partitions are made of frame work of plate latches on either side being covered with several layers of plaster boards and having the space between the wallsides mostly filled with mineral wool, a need has arised to be able to effectively fire-seal led-throughs in such frame-work walls. None of the above mentioned known arrangments for lead-throughs can in an easy way be placed in an optional position in a frame-work wall. To be able to place the led-through in an optional position means that it does not have to be placed in connection to, and to be carried by, a latch or a nogging piece connecting to latches. This optional placing furthermore means that the lead-through will completely be carried by the surface covering of the wall preferably being made of plaster boards. When there is a fire the plaster boards facing the fire centre will successively be destroyed. In order to delay as much as possible this destruction due to the heating, it is important that the wall is not exposed to other strains than those caused directly by the fire. Due to the heating there are certain movements in the plaster boards, whereby a led-through, which rigidly joints the two outer surfaces of the wall, can give rise to checkings on the plaster boards and hurry up the falling to pieces of the wall. Therefore a lead-through must have a certain movability at the same time as it, also when it is exposed to the heat from a fire-centre, must be tight and prevent hot fire-gases as well as poisonous and/or corrosive gases arised from fire from passing the lead- through. DISCLOSURE OF THE INVENTION
The purpose of the invention is to show an apparatus rendering possible a quick and simple mounting of a fire-sealed lead-through in a frame-work wall with plaster board covering. According to the invention this is made so that a premanufactured arrangement comprising two concentrically arranged pipes pushed into each other are placed in a hole being made in the frame work wall, the free ends of the pipes being connected to an outer surface of the frame work wall each. The inner pipe of the two pipes is completely or partly filled with an elastic fire-resistant foam material precompressed transversely to the longitudinal direction of the pipe. The arrangement is characterized among other things in that the foam material filling of the inner pipe in the mounted position of the arrangement partly reaches into the outer pipe and with pressure presses against its inner surface and thus seals the gap between the two pipes.
BRIEF DES CRIPTION OF DRAWINGS
Figure 1 shows a first embodiment of an arrangement for fire-sealing of a lead- through according to the invention and Figure 2 shows a second embodiment of an arrangement for fire-sealing of a lead-through according to the invention.
BEST MODE(S) FOR CARRYING OUT THE INVENTION
In Figure 1, which in cross section shows a first embodiment of an arrangement of fire-sealing of a lead-through being mounted on a wall, 1 designates a part of a wall being built on not shown latches, said wall comprising double wall boards 2, 3 being arranged on either side of the latches. The space between the boards is filled with an insulating material in the shape of mineral wool 4. In the wall boards 2, 3 holes opposite each other have been made. In the hole in the wall board 2 a lead-through 10 has thereafter been placed consisting of an outer pipe 5, an inner pipe 6 arranged inside this, said pipe 6 being filled with an elastic fire-resistant foam material 7 precompressed transversely to the longitudinal direction of the pipe. One of the end parts of the outer pipe 5 has been formed to an outer flange 9, which has been fastened, in a sealingly manner, to the outer surface of the wall boards 2. In a start position the inner pipe 6 has been completely drawn into the outer pipe 5, but after the fact that the lead- through 10 has been mounted into the wall boards 2 it has been pressed out of the inner pipe 6 until its free end part, through a screw, bayonet or similar socket has been able to be joined together with a flange 11 inserted from the other side of the wall into the hole in the wall boards 3, said flange being sealingly fastened to the outer surface of the boards 3. In order to admit certain movements in the wall material caused by the heat, when there is a fire, and to facilitate the mounting of a lead-through into a wall, ther is a gap 12 between the outer pipe 5 and the inner pipe 6. The gap 12 has been made fire-resistant gas-sealing by the fact that the foam material filling 7 of the inner pipe 6 with a part 8 reaches into the outer pipe 5 and with pressure presses against its inner surface.
The embodiment shown in Fig 2 of an arrangement for sealing of a led-through differs from the embodiment shown in Fig 1 only in that way that the inner pipe 6 is provided with a flange 13 being manufactured in one piece together with the pipe. Thus the risk for possible gas leakages through the joint between the inner pipe 6 and the loose flange 11 have been eliminated. This embodiment requires a greater exactitude when mounting, because the whole inner pipe 6, with its precompressed foam material filing 7 shall be fitted into the outer pipe 5, something which is done inside the wall. The fitting is made more difficult by the fact that it is the foam material part 8 which is expanding in free condition, which firstly shall be inserted into the outer pipe 5, and in which it shall press against the inner side of the outer pipe with highest possible pressure. In order to prevent that the part 8, when it is not surrounded by the outer pipe 5, shall expand so much that it is not easy to have it placed in its original position again, it is reinforced with a not shown net of plastics or textile which, when part 8 is reasonably expanded, is streched out and prevents further expansion without preventing the part 8 from pressing onto the inner surface of the outer pipe 5 with full pressure when being in the mounted position of the led-through. Furthermore the net is designated in such a manner that it does not prevent cable running through the lead-throughs.
