The present invention relates to a means of fire protection for the frame for input cables, input pipes or something similar.

When the cables, pipes or the like must be carried out through walls, ceilings, roofs, upper floors or buildings or anything like that, there are often regulatory requirements regarding fire protection. Such requirements are usually stipulate that the input pipe, entrance cable or the like must be able to withstand fire for the required period of time, without the risk that the fire will spread to the other side of the wall, etc. depending on the type of building requirements can be of different hardness. Frames of this type can also be used in containers, cabinets, etc.

Each frame can take a number of different cables and/or pipes. Cables can be electrical, communication, computer, etc. and pipes can be used for different gases or liquids, such as water, compressed air, hydraulic fluid or gas used in the kitchen.

The present invention is that the means of fire protection should be relatively elastic and, thus, to be able to adapt to different types of frames for the input cables, input pipes and the like. Also a problem izobreteny what is that means fire protection needs to function well regardless of the number of cables, pipes and anything carried out through a wall or the like.

The next task is that the temperature in case of fire or other heat exposure is supported by the relatively low side walls and the like, are not affected. Furthermore, an additional task is something that should be relatively easy to place cables, pipes and the like in the wall, etc. both before and after a possible fire or other heat exposure.

In addition, the present invention is that the means of fire protection must be able to be modified, that is, to ensure that the supply of existing frameworks means of fire protection in accordance with the present invention. Thus, it should also be possible to mount the tool of fire protection over existing cables etc.

According to the present invention a means of fire protection is located in the protruding part of the outer frame through which must be entered cables, pipes, etc. Protruding portion extends from the frame at least one side wall of a building or the like, etc.

Additional objectives and advantages of the infusion is his invention will be apparent to a person skilled in the art when reading the detailed description, below, the preferred embodiments.

The invention will be described below on the example and with reference to the attached drawings, on which:

Figure 1 is a perspective view of a wall with a frame equipped with a means of fire protection in accordance with the present invention, and

Figure 2 is a perspective view of the frame of figure 1 viewed from the opposite side of the wall.

The expression "horizontal", "vertical", and similar expressions used in this description, is defined with reference to the direction shown on the drawings. To a person skilled in the art will understand that the frame of the input cables and the like can have any direction. Thus, the frame can be attached to walls, ceilings or floors.

According to the embodiment of the present invention the outer frame 1 input cable, pipe culverts, etc. placed in the hole in the wall 8. The outer frame 1 has a protruding portion 2. The protruding portion 2 is formed by two horizontal walls 9 and the two vertical walls 10. Thus, the protruding portion 2 has a General rectangular shape in the embodiment shown and continues for some distance from one side wall 8. To a person skilled in the art will understand that the outer frame 1, as well as the protruding portion 2 may have the any General shape, without deviating from the scope of the present invention. The protruding portion 2 is either a separate part attached to the outer frame 1 or to the wall 8, or is a part of the outer frame 1. If the salient part 2 is a separate part, it can be used, any method of attachment to the outer frame 1. Such fasteners may be bolts, rivets, welding, solder, adhesive, etc.

In other embodiments (not shown) the means of fire protection in accordance with the present invention attached to both sides of the wall 8 or the like. In a further alternative embodiment of the outer frame 1 is attached to one side wall 8 or the like, while the protruding portion 2, which includes means for fire protection, attached on the other side. Usually the walls 9, 10 of the protruding part 2 attached to each other detachable manner, which means that the protruding portion 2 can be mounted after installation of cables, pipes and the like. For such after installation of cables, etc. at least one of the walls 9, 10 of the protruding part 2 is first removed, and the remaining part are the cables. The next step is to re-installation of the protruding part 2 with the addition of the dismantled wall or walls 9, 10. Simultaneously, the protruding portion 2 prikreplena to the frame 1 or the well 8.

The outer frame 1 must take one or more internal frames 6. Internal frame 6 have one or more inputs 7 cables, pipe culverts, etc. to accommodate 5 cables, pipes and the like in a sealed form. Since the exact form inputs 7 cables, etc. are not important to the present invention they are not described in detail here. Internal frame 6 and the inputs 7 of cables placed in the above-mentioned inner part 6, usually do not continue in the protruding portion 2 of the outer frame 1. The protruding portion 2 has a through hole 3. In the hole 3 protruding part 2 posted a number of sheets (layers) 4 expanding upon heating of the material.

Layers 4 expanding when heated, the material located on the walls through which the protruding portion 2 is formed a series of compartments. Walls forming compartments, continue within the holes 3 protruding part 2, that is, between two of its opposite walls. The number of compartments is usually selected according to the number of compartments in the outer frame 1. Each compartment will typically take one or more of the 5 cables, pipes and the like. Layers 4 expanding when heated, the material should act as fire protection. Thus, expanding the material will expand when exposed to intense heat, such as in the case of fire. Expanding when heated, mA is Arial, often referred to as the swelling material used for fire protection, well known in the art, and the particular material is not critical to the invention provided that the material is expanded sufficiently to meet the requirements presented below. In this description, the expression "expanding when heated, the material is used for simplification.

Usually layers 4 expanding when heated, the material are possible walls intersecting hole 3 protruding part 2, directed from the wall 8 and the vertical and horizontal walls 9, 10 of the extension 2. You can also replace the layers 4 on the inner wall of the protruding part 2 coatings of expanding upon heating of the material. Expanding when heated, the material may also be applied as a paint. Thus, in this case, the inner wall of the protruding part 2 and/or possible wall intersecting the hole protruding part 2, we covered the expanding while heating the material. In this embodiment, each cable 5 or something like that will be surrounded by an expanding when heated, the material with the four sides of the protruding part 2.

The 5 cables, pipes and the like, located in the inner part 6, will be held between the sheets 4 of the expanding material placed in the serving BS is t 2 outer frame 1. The protruding portion 2 should normally be directed to the side wall 8, with which the risk of fire is greatest. As noted above, you can also perform the protruding part 2 from each side wall 8. This can be done, if there is a potential risk of fire or intense heat from both sides of the wall 8.

When using the present invention the 5 cables, pipes and the like are mounted in the same way as before. The only difference is that the cables 5, etc. are also carried out through the protruding part or part 2 and between the sheets 4 of the expanding material.

In the case of intense heat, as in the case of fire, the leaves 4 of the expanding material will expand. The material will expand and completely fill the protruding portion 2 of the outer frame 1. Possible soft tube or something like that can collapse under the pressure of an expanding material, the tube will be sealed, preventing further spread of potentially dangerous material. In addition, the expanding material will absorb heat and thus contribute to lowering the temperature of the cables 5, etc. and other parts of the side walls 8, not exposed to direct fire or other sources of heat. Depending on the extent of the damage is often enough only is to be replaced after a fire, the cables 5, etc. and leaves 4 expanding upon heating of the material. Thus, it is relatively easy to replace the damaged parts at relatively low cost.
