Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a fire-retardant coating for protecting heat-sensitive components in petrochemical facilities, in particular electrical cables, and other heat-sensitive components such as fulcrum support members. Regarding.

Most electrical cables today are wrapped in plastic for insulation purposes. The plastics used for cable sheathing are primarily heat sensitive and flammable plastics. Therefore, a number of proposals have already been made for cable fire protection. For example, the cable is coated with a self-dissolving fire retardant, such as is known from German Patent No. 2,059,969. This method is particularly expensive, especially if adjacently laid cables have to be protected from fire hazards.

Therefore, cable route coverings with a protective jacket configured in the form of a tube have already been proposed.

This protective jacket is formed from two layers of steel plate.

With layers! The space between the two is stuffed with mineral wool. In order to prevent corrosion, one can use rust-free or at least galvanized iron plates to construct this type of protective jacket, but this requires a large amount of expense. Moreover, metal protective jackets require their own retaining devices due to their self-weight. These protection devices are relatively expensive and not always easy to install. The basic problem of the invention is to develop fire-retardant coatings that are cheap to manufacture, easy to install, and yet provide sufficient protection. It is in.

This problem is solved according to the invention by a fire protection coating made of a durable mineral wool structural component and having a fire protection laminate at least on the outside.

By mineral wool we mean those with a high softening point, in particular asbestos, mineral wool and/or ceramic wool. As a fire-retardant layer, flammable or non-flammable fire-retardant materials, such as German Patent No. 20
Advantageously, it is possible to use one such as that known from publication No. 59969. Such fire protection coverings can be adapted to construction site situations because they are made of cantilevered structural members that do not require a separate supporting framework. Although Mineral Cool itself does not provide the necessary protection and does not form a fire-retardant layer, it was surprisingly found that: In other words, there is an exchange effect between the two,
Only through this exchange action is protection against high temperatures achieved, even if the mineral coolant and/or fire protection layer still contains a small amount of organic binder, which decomposes in a fire. Due to the dynamic process of temperature rise in the event of a fire, it is not necessarily necessary for the coating according to the invention to withstand maximum temperatures in the region of 1000.degree. Rather, the ingress of heat is greatly retarded to keep the inside of the sheathing, for example the wire, functional for the required time.

Mineral wool is protected by a fire barrier in case of fire. In particular, fire protection layers average out local heat differences due to their relatively large heat transfer properties. Similarly, the unevenness of the mineral wool plate is averaged out. Furthermore, convection through the mineral wool is prevented by the blocking action of the fireproof layer. On the other hand, the following unexpected findings were made. That is, mineral wool can serve as a sufficiently stable support for the fire protection layer when the binder of the fire protection layer decomposes.
Its mechanical stability is therefore reduced. Exchange effects have not yet been studied in detail. However, experiments under suitably harsh conditions show mutual support.

Such fire protection coatings do not require large technical outlays and
The internal cables make it possible to maintain its functionality at least until the necessary signals for the activation of a safety device, such as a safety valve, are transmitted.

In particular, at least two or three of the mineral wool structural elements of the fire protection coating according to the invention are arched or bent in at least one direction, so that they are angled with respect to each other. Sealing problems that can occur in the case of elongated plate structural members are to a large extent avoided.

The fire protection coating according to the invention can therefore be made, for example, from four mineral wool structural elements essentially L-shaped in cross-section or from two mineral wool structural elements essentially U-shaped in cross-section. These structural elements enclose objects that must be protected from the effects of heat, such as cables, supply pipes or support elements or spaces in which conduits protected from the effects of heat are laid.

The mineral wool structural part of the fire protection coating according to the invention is in particular a compressed molded part. The compression is particularly prior to the final release of the binder. Mineral wool structural elements are compressed, especially in the connecting areas. In particular, it is compressed to form an acid-type member.

This acid-type member applies to a longitudinally extending bonding region.

The mineral cool structure of the fire protection coating according to the invention is particularly impermeable, i.e. liquid-tight, and in particular gas-tight. These structural members therefore have metal sheets built into them. This metal foil in particular extends essentially over the entire surface of the structural component.

A preferred embodiment of the invention has an outwardly folded edge formed in the shape of a mineral maggot. Each of the mineral cool structural elements of the invention can be formed by a plate that is essentially rectangular in plan view, the entire edge of which is configured in the form of a seven-lunge and is bent outwards. , the longitudinal edges are preferably each bent at 45°, so that a line jacket with a rectangular or square cross section can be assembled from a single piece. In this line jacket, the 72-angular edges of the parts touch each other with their large surfaces, which facilitates their mutual sealing. The edges, which can be connected to corresponding edges of another structural member to extend the conduit, are bendable through 90 degrees.

In the fire protection coating of the present invention, curved corner pieces and/or corner pieces that cover the coating area touching the sides and corners of the coating are particularly provided with a width corresponding to at least double coating wall thickness. Since this is possible, good sealing of the corners is ensured with and\.

At least a few of the structural elements can be designed in the form of tablets and/or bridges for the production of covered conduits.

The coated mineral wool structural component according to the invention has, as already described, an integrated metal foil, but can alternatively or additionally have a full-area net reinforcement. This reinforcement is particularly provided in the center of the wall or in the inner half of the wall. Such metal net reinforcement presents a dual challenge. The reinforcements with , on the one hand, serve to stabilize the coating and, on the other hand, increase the insulating effect of the coating, since the heat is laterally distributed.

The mineral wool structural element can have recesses, in particular recesses, for receiving and fixing correspondingly formed fastening elements and supporting elements.

Particular guidance in this regard is given in the following description of advantageous embodiments.

The individual mineral cool structural elements are interconnected, especially under pressure forces. This rounding is provided with plates or clamps on both sides of the interconnected mineral wool structural members and pressed against the structural members by fastening elements such as screws and nuts. . Especially if it extends over the entire range of connection and in Phase I.
It is also possible to provide a plate or rail that evenly distributes the pressing force of the K-bonded mineral wool structural members. In that case, the connection range can be arranged in various planes and in a labyrinth style.

Said mineral foil preferably extends over the entire coverage area of the associated structural component and is inserted into the structural component, in particular prior to removal of the bonding means. Since the metal foil does not particularly reach the edge layers of the mineral wool structure, its contact surfaces, at least the edges and edges on the surface, are free from the metal foil.

The fire protection coating according to the invention can be constructed in one layer or in multiple layers. This applies in particular to the undercoated area. A multilayer construction is advantageous from all points of view. This configuration has the advantage, on the one hand, that the coating can be assembled from a single piece that is thinner and therefore lighter and more easily deformable. On the other hand, intermediate layers can be provided between the individual members. After all, sealing problems with this arrangement are greatly reduced by mutually offsetting the respective coupling areas of adjacent parts.

The mineral wool of the component is particularly suitable for 100~500°
It has an empty weight of 50-250 kg/m3.

The individual layers can be formed into at least the corner and side regions of identically formed mineral wool structural elements. The inner layer has a particularly higher density than the outer layer, so that the functionality of the coating is also guaranteed if the outer layer is subjected to intense thermal action.

Mineral wool becomes easy to sinter at a temperature of about 900°C.

Even at such high temperatures, the outer NJ is constructed with the aim of providing the best thermal insulation in terms of its density. In this case, the high temperature does not reach the inner layer of the trowel.

As already mentioned, intermediate layers can be provided in the case of a multilayer construction. This intermediate layer consists in particular of a thin metal foil. Alternatively or in addition to this, a separate fire protection layer can also be provided in this case.

The softening point of mineral wool structural components is in particular above 900°C;
- up to 50% by weight Elo.

Up to 12-18 weight percent is 12-20
Up to 1 weight percent Cab, 1 B-15 weight percent Mfo, and 4-10 weight percent iron oxide.

The average diameter of the Mineral Cool fibers of the Mineral Cool structural member is preferably 2 to 6 μm.

The bonding means used to produce mineral wool structural elements are in particular heat-resistant polymers, in particular phenolic resins.

The coupling means part is 1.5-8 fold i parcey) K Jf, %
2-51i amount percent.

The fire protection laminate can in principle be installed after the final installation of the mineral wool structural element. However, it is already installed before installation. Moreover, it can also be attached to the area of each contact surface. It has been found to be particularly advantageous to have structural components which are provided with a non-combustible or flame-retardant retaining layer on the opposing contact surfaces and which are bonded to each other, especially by means of adhesives having such properties.

The mineral wool structural parts provided for the installation of fire protection coatings according to the invention can in particular be constructed so that they can be stacked one on top of the other and without intermediate layers, which makes their transport and storage extremely easy.

In particular, the seven juxtaposed flanges of adjacent structural elements have a width that corresponds at least to the double wall thickness of the elements.

In one preferred embodiment, a support cradle is provided to which the structural members can be fixed. This support frame consists, in particular, of several vertically arranged frames which are fixed to and surround the cable trough.

These frames can be constructed from U-shaped rails,
Connecting angle elements are provided for joining these rails. These frames, in the preferred embodiment, are each made of four flat irons and are connected to each other through angle rails that connect the flat irons of the individual frames, and the flat irons and the angle rails are connected by threaded holes. These holes are especially long holes. If necessary, the individual frames are also connected to each other by rails parallel to the cable route.

These rails also have screw holes.

For the fastening of the mineral wool plates to the support frame, it is advantageous to be provided with holding elements which can be threaded through the plates or inserted into these plates, each of which is provided with a safety plate. Equipment is also attached.

In a preferred embodiment, for fixing the mineral wool plates, fixing elements are provided which can be pressed into these plates from the end faces and screwed onto the support frame, each of these fixing elements having two side parts. one of which has a point that can be pressed into the mineral wool board from four sides, and the other has a slotted hole that serves for screwing into the support frame.

In order to fix the mineral cool plates to each other, a connecting member can be provided which can be fixed in a cutout in one of the plates. However, these connecting elements can also be curved or spring-shaped. Adhesives can be used for fixing the joining parts, in particular consisting of asbestos cement.

This adhesive is particularly applicable to German Patent No. 205996
I have already mentioned several times that it is a self-dissolving fire retardant listed in No. 9.

The fire protection layer with mineral wool structural elements is made of a particularly mechanically resistant and weather-resistant material.

An example will be shown and nine figures will be described in more detail.

The first embodiment of the fire protection coating according to the present invention
The part shown in perspective view has a structural element 1 which is essentially KU-shaped. This structural element is made of compressed mineral wool material and has a fire protection layer on the 11 sides facing downward in the figure, the edge 2 of which is in the form of a flange K11l lying in a horizontal plane. This edge 2 is followed by approximately 45 sloped side walls, which give way to a flat bottom.

The base width is essentially three times the depth of the four members. The edge 2 has recesses 3 facing each other at uniform intervals. The cable holder 〇 side end (not shown) fits into this recess. These cable holders can then consist of straight webs, but they can also have corrugated recesses to facilitate the laying of individual cables. The cable is thus supported by the structural members and surrounded by air on all sides within the conduit. A support cradle for the cables is omitted.

The structure made up of several structural members 1 arranged one after the other is covered by nine structural members 4 arranged one after the other. Only one structural member 4 is shown in FIG.

The structural element 4 corresponds in its shape and dimensions to that of the structural element and is also made of compressed mineral cool material and is provided with a fire protection laminate on the outside 1, ie on the side facing upward in the drawing. The structural element 4 rests with its edge 5 on that of the element 1 and is tiled relative to the underlying element. In each transition position between the parts 1 and 4 there is provided an essentially KU-shaped metal clamp 6. Clamp 6
fits into the edge 2.5.

However, it has proven advantageous to provide a fixing element for the rounding of the clamp 6, for example a screw.

Figures 5-5 show cross-sections of the fireproof coating. This covering essentially corresponds to the covering shown in FIG.
has. However, in the coating shown in FIG. 3, there is provided a residual intermediate piece between parts 1 and 4 which serves as a spacer.

In the fireproof covering shown in FIG. 4, members 8 are provided below the lower part #40, which are also arranged in the front and rear.

This member is in close contact with the member 4 and is offset relative to the member 4 (Fig. 10). The fire protection coating shown in Figure 4 has a double layer in the lower region.

In the case of the fireproof covering shown in FIGS. 9M5 and 5, U-shaped rails 9 and fixing screws 10 are provided for fixing the upper part 4 to the lower part 1, 1.8. The U-shaped rail 9 has its base on the edge of the component and is in particular longer than the component. The U-shaped rail thus serves to secure several parts simultaneously. The U-shaped rail spans the entire length of the flameproof conduit.

The spacer 7 and the fourth spacer provided in the case of the fire protection coating shown in
Parts 8 arranged under part 1, which are provided in the case of the fire-protective sheathing shown in the figure, are in particular made in each case of similarly compressed mineral wool material, which parts are at least externally fire-protected. It has laminated layers.

FIG. 9 shows that the fixing screw can pass through said cable holder 11 if desired. However, in order to prevent the formation of thermal bridges, it is advantageous for the cable holder 11 to be made short. The cable holder therefore does not come into contact with the fixing screw 10, as shown in FIG.

In the fire protection coating shown in FIG. 4, there is another fire protection laminate between component 1 and underlying component 8. This allows a thin metal foil, for example an aluminum foil, to be provided between the two component layers.

Such a metal foil can also be incorporated into part 1.4.8. This provides the component with reinforcement on the one hand and a seal against the ingress of gases and liquids on the other hand.

The individual parts 1, 4.8 can each be stacked interleaved with one another, like the part shown in cross-section in FIG. 4, which greatly facilitates transport and storage.

Figures 6-9 show how the fire protection coating according to the invention is actually installed.

The pillar 12 is shown in FIG. This column has a support part 13
It is fixed. The support part 13 has an underframe 15 fixed thereto with a clip 14 and configured essentially in the shape of a ladder;
This frame consists of several single segments that are each screwed together at their end faces. On the underframe 15, first one layer of the components 1 from top to bottom is placed. 7th
As shown, the lower part 1 has newspapers that work together to seal each other.

The same applies to the upper part 4.

This element can rest connected to the edge 2 of the lower element 1. However, if the cable is laid loosely, i.e. the lower member 1
This is the case when it is desired to lay a cable without a cable holder in the conduit constituted by the upper member 4 and the upper member 4. If the upper member 4 is a rest, the metal clamp 6 can be tightened. After this, the U-shaped rail 9 can be fixed with fixing screws 10. The cables can be laid before placing the upper part 4 or can be brought in afterwards.

If it is desired to insert the cable holder 11, it can be inserted into the recess in the lower part 1 for this purpose before placing the upper part. The continuous cable holders 11 can be connected to each other before or after, in particular via 4116 made of iron plates. The cable 17 to be protected can then be laid into this trough (FIG. 9).

Next, cover with the upper member 4. Furthermore, as can be seen from FIG. 9, the lower rail 9 can be fixed to the lower member 1 with special screws K, so the upper member 4 can remove the lower rail 9 if necessary. You can remove it without removing it.

FIG. 10 shows that the individual parts 1.4.8 can in particular be provided offset from one another.

FIG. 11 shows a perspective view of a portion of a fire protection sheath assembled from four structural members 18. These parts are member 1
, 4.8, or made from a single piece of compressed mineral cool material. These components also have at least a fireproof laminate on the outside. Part 1
The edges of the 8 are each bent into a 7 flange and are therefore in close contact with the edge flanges of the adjacent structural members and are connected to each other via a clamp and/or a U-shaped rail 9 corresponding to said clamp 6. Can be combined.

In an embodiment not shown, the fire protection coating according to the invention can be constructed from individual structural components. The entire edges of the structural elements are bent outwards, so that the edges of longitudinally adjacent structural elements one after the other also touch one another and are connected to one another via clamps or U-shaped rails. be able to.

The coating according to the invention can also be used for the protection of other objects, in particular structural elements, such as steel support members, and also for the protection of supply control conduits or hydraulic control conduits.

In the embodiment shown in FIG. 12, the individual rails 1
9. A support frame consisting of 20 is provided, to which individual structural members can be fixed, each of which consists of a corner piece, an edge piece, and a plate-shaped intermediate piece of two layers. It consists of

In the embodiment of the fire protection sheathing according to the invention shown in FIG. 15, a protection device for cable routes is provided with a cable trough 101 for the adjacent cables. This cable tank has a support member 1 fixed to a wall 102.
It is fixed at 03. This protection device essentially consists of a protective jacket 104 which is fastened to vertically extending frames 105 which are connected to the cable trough 101, in particular via an intermediate piece 121. It is fixed by screws 106.

The frame 105 is composed of two horizontal rails 107, 108, two vertical rails 109, 110, and four connecting angle pieces 111. The connecting angle pieces connect the horizontal rails 107, 108 with the vertical rails 109, 110. Each of the rails 107 to 110 can be constructed from several parts that are slidable axially opposite each other, so that they can be adapted to the current spatial conditions. In the figure, only two rails 109 and 110, each extending vertically, are shown in a corresponding multi-part configuration. These rails each have two short rails 112,
115 and an intermediate portion 114. The rails 112, 115 are axially movable in this intermediate part and can be secured by means of coupling means, not shown, for example screws.

The protective jacket 104 has a rectangular cross section.

The walls of this jacket are formed from interconnected flat mineral wool plates approximately 30 to 80 mm thick, in particular 50 mm, namely a base plate 115, a cover plate 116 and two side plates 117, 118. .

Plates 115-118 are each of multi-part construction in the illustrated embodiment. That is, it is composed of a plurality of nine rectangular single plates with the narrower 91 sides facing each other. These boards 1
For the fixation of 15 to 118, a fixing member 119, which is essentially nail-shaped, is provided.

Installation of plates 115-118 is performed in the following order.

First, the bottom plate 115 is fixed to the two frames 105 with two fastening elements 119, respectively. At the rounding, the fixing element 119 is passed through the plate from the inside of the frame. The end of the protruding element 119 is attached to the tightening plate 1
20 to make it safe or make it safe by folding it.

Once the bottom plate 115 has been fixed to the two frames 105, the two side plates 117, 118 can begin to be attached to both frames 105, for which also the fixing elements 119 can be used. However, before that, the side plate 117 facing the bottom plate 115
, 118 can be coated with a heat-resistant adhesive.

Further fastening elements can additionally be used to fasten the side plates 117, 118 to the bottom plate. These fixing elements can be designed in the form of curved members or springs and can be associated with corresponding recesses or grooves in the base plate 115.

When the two side plates 117 and 118 are installed, the cover plate 116 can be attached. This installation can be done in the same way.

Two frames 105, bottom plate 115, side plates 117, 118,
The structure comprised of the cover plate 116 forms a unitary component that can be prefabricated at the factory or, if desired, assembled at the construction site. It can then be joined from the ends to other correspondingly designed components. For this purpose, in addition to or instead of a heat-resistant adhesive, connections can also be provided which are of jointed, U-shaped or spring-type construction and accommodated in corresponding dimensions in adjacent components. elements can be used.

The fire protection coating according to the invention has the following advantages: it can be retrofitted onto existing equipment, for example for cable routes, and it can also be fitted when new cable routes are installed, and it has a particularly high insulating effect. It has the advantage of being characterized by In addition, the configuration is simple and there is no need for anything to firmly support the frame 105.

The protective jacket 104 of the covering, in particular the side plates 117, 118
The protective jacket can be provided with a ventilation flap 122, which improves the circulation and ventilation inside the protective jacket, as well as the exhaust air and thus also the cooling of the cable routes laid therein. The ventilation flap 122 can be pivoted directly to the protective jacket plate. However, it is also possible for the ventilation flap to be pivoted to the insert 123 in a frame-shaped configuration.

This insert can be fixed in a plate cutout corresponding to its dimensions.

The ventilation flap 122 and, if appropriate, the insert 125 associated therewith are made of a particularly heat-resistant hard material,
