Description

Procedure and device for manufacturing a building closure panel for fire protection as well as building closure panel for fire protection manufactured with them.

The invention relates to a method for manufacture a building closure panel for protection against fires, especially a door leaf protection against fires, comprising an outer shell, especially of sheet metal, surrounding a filler consisting of materials Binder minerals. In addition, the invention concerns a building closure panel for fire protection, especially a fire protection door leaf, comprising an outer shell, especially sheet metal metallic, which surrounds a filling formed by mineral materials with binder. Finally, the invention concerns a device for manufacturing a building closure panel for fire protection, especially a door leaf fire protection, comprising an outer shell, especially of sheet metal, which surrounds a filling formed by mineral materials with binder.

Therefore, the invention generally relates to building locks suitable for fire protection, such as fire protection doors and gates, and It concerns especially a panel designed for closing building of this class for fire protection, that is, for example, a sheet of a fire protection door or a sheet of a fire protection gate. The doors known fire protection, such as those that can be get on the market, present an outer sheet metal envelope metallic and an inner filling of a fireproof and insulating layer that It is formed by a fiberglass or wool mat rock. The housing is formed, for example, by a sheet drawer of door that forms a wide side of the door leaf, as well as several or all the narrow sides of the door leaf and that is closed by means of a lid.

A door leaf protection against fires formed with this door leaf drawer is known for WO96 / 07004.

The insulating materials used in general as fillers in fire protection doors  they consist of mineral fiber plates (wool plates of rock or glass wool plates). The manufacturing is carried out in such a way so that the plate-shaped filling is placed inside the drawer and the drawer is then closed by means of the lid. Plates Mineral fiber are supplied for different types of doors with a suitable length, width and thickness and they remain as Stock by the manufacturer of the doors. Such mineral wool mats are manufactured, for example, by firms Grünzweig and Hartmann AG. These mineral wool plates known generally consist of mineral wool, specifically wool of rock or glass wool, and are kept in the form of a plate by medium of an organic binder, cutting the plates conveniently to the desired size.

In fire trials it has now been seen that doors built according to this known class have failed, even when the temperatures measured at the door had not reached still the limit values allowed. However, it has occurred passage of fire through the door.

The known devices for manufacturing such fire protection doors present equipment for provide mats of mineral material in size and thickness adequate. Depending on the nature of the coating, they are provided also, of course, other known devices for manufacturing the lining, such as equipment for manufacturing the drawer and equipment to manufacture the lid. In WO96 / 07004 are hinted at equipment to manufacture a door leaf housing. They also have an insertion kit to insert the mineral wool mats and a welding device, in which the lid and the drawer are joined together. Provisioning with proper mats is complicated, since the mats they have to be supplied "just in time" to the process of manufacturing or else mat sizes have to be maintained corresponding for each desired size.

It is known from document FR 2568622 A procedure to manufacture a door of protection against fires in which it enters the cavity of an envelope of outer sheet a filling of vermiculites with organic binder. Therefore, this document describes a procedure for manufacture a fire protection door leaf with a outer sheet metal housing surrounding a formed fill by mineral materials with binder, first manufacturing the outer shell with a cavity that is accessible from outside to through at least one smaller size housing opening compared to the length and width of the cavity, introducing a flowing mixture of filler material based on mineral materials with organic binder through the al less an opening of the housing to form the filling.

The document US-A-4,799,349 describes a sheet of fire protection door made of sheet metal with the features of the preamble of claim 10 attached.

US 4,411,389 describes a filling cannon that is suitable for injecting a mixture of solid particles and liquid binder in a cavity, for example a hole in a building wall. It can be filled like this The wall with thermal insulating material.

The problem of the invention consists in provide a procedure and a device for manufacturing a building closing panel for fire protection of the class cited at the beginning, with which they can be manufactured from cheaper way than until now building closure panels for Fire protection with improved fire resistance. In addition, it is intended to create a building closure panel for fire protection that can be manufactured with this procedure and with this device and that offers resistance improved fire

The problem is solved by procedure with the steps of claim 1 attached, a device with the features of claim 12 attached and a building closure panel for fire protection with the features of claim 9.

Advantageous embodiments of the invention are Subject of the subordinate claims.

To manufacture the building closure panel for fire protection, such as especially a sheet of fire protection door, it is planned according to the invention a manufacturing process characterized by manufacture the outer shell with a cavity that is accessible from out through at least one opening of the housing, preferably with a dimension smaller than the length and / or the width of the cavity, and introduce a filling material based of mineral material in pourable or flowing form and a binder organic through the at least one opening of the housing to Form the filling.

Therefore, the invention provides a method for the manufacture of fire protection doors or similar fire protection closures, in whose procedure is filled a housing of the closing panel of building with really loose mineral wool or other insulating material pourable, flowing and / or individualized based on materials minerals

The filler material (insulating material) is supplies or provides in flowing form, especially in form of bulk product preferably without binder, for example in a silo. A silo of this class contains, for example, mineral wool in the way it is spun. This loose filler material it is then insufflated by means of an apparatus in the hollow housing of the building closure panel for fire protection with the aid of a fluid, such as, for example, compressed air. During this introduction of the pourable mineral insulating material granulated or in the form of fiber is also added, preferably to the same time, an inorganic binder.

Indeed, in the fire tests carried out by the applicant it has been recognized that the failure of the doors known fire protection can be attributed frequently to a development of combustible gases from of the organic binders of mineral wool mats employed so far. In the fire test these gases fuels have escaped the known door leaves of fire protection on the far side of the fire and have inflamed, which has led in the fire test to come out flame on the far side of the fire and, therefore, the door. On the contrary, if an inorganic binder is used to bind the particles of mineral insulating material, this does not then leads to combustion. In general, the inorganic binders also withstand much more temperatures higher than those that support the organic binders used currently in the mineral wool mats obtainable in the market and they begin to volatilize already at temperatures starting of approximately 150 ° C.

Due to the special kind of filling by insufflation medium of loose filler material under addition simultaneous binder, the manufacturing process is regardless of the shape of the mats supplied. From a  reserve container can be filled all kinds of panels Building closure for fire protection (for example, fire protection door leaves, fire protection gates, protection gates fire protection). The complicated internal logistics is suppressed and outside the manufacturing company to supply the manufacturing device with suitable insulating mats. Be they also suppress special fabrications of wool mats ore and storage equipment necessary for storage from the same. It does not depend on whether the filling plates have trimmed or low cut somewhere. It is filled in a simple way the remaining cavity of the outer shell of the closure panel of building. The invention provides such filling procedures as an insufflation procedure or an injection procedure. In another technical sector nowadays techniques are used Injection of mineral fibers for roof coverings. With This procedure designed for roof coverings could be also fill the housing of a building closing panel to fire protection correspondingly modified and varied.

Due to the process according to the invention no it is only independent of door sizes and independent of door thicknesses, but with the procedure of corresponding processing can also vary the amount of filler material to be introduced in the housing. It has so in manufacturing the possibility of influencing the density of the flame retardant layer introduced into the door. Although special internal structures are provided inside the building closing panel for fire protection, it is not Additional work is necessary on the filling material. The filling material simply adopts the shape of the cavity to be filled. It can also be manufactured firstly the housing with the desired shape, that is, For example, the lid and the drawer of the door's leaf. The opening of the housing does not have to be so large that a preformed mat can pass through it. Is enough to leave open, for example on the lower side or on another narrow side, a small opening to introduce the material of loose fill and binder, whose opening barely calls the attention after filling and / or can be closed (also from optically attractive way). The inorganic binder added to the filler material also has the additional advantage of serving at the same time as a binder between the material of padding and outer shell. They are superfluous fixations or sticks additional.

They are already known by EP documents. 0 280 306 A1 and BE-A-571 576 ones procedures for manufacturing a door or gate panel in the that a panel housing formed by sheets surrounds a cavity that  It is completely filled with a plastic foam. But nevertheless, base plastic foam materials are used for this known organic (for example, PU sponges) that are completely unsuitable to form a protective closure fire protection. In addition, such plastics also contain, naturally, organic binders that would lead to failure by combustion when door or gate panels were exposed thus manufactured to a fire test.

On the contrary, in the procedure according to the invention a material-based filling material is introduced Mineral in the cavity of the building closing panel, performing the introduction with the addition of a binder (inorganic) in form turbulent or sparkling.

This is preferably done by insufflation or injection of loose filler material into the cavity and addition of the binder through the at least one opening of the housing. By insufflation or injection, the loose filler material, which leads to air occlusions or other cavities inside the filling material later obtained. These air occlusions or cavities serve, just like the known mineral wool mats, for the heating.

To enter the filler material so uniform in the cavity the filling material is blown preferably through a rigid tube, a flexible tube or Similary. The rigid tube is inserted into the cavity of the panel building closure through the at least one opening of the Case. The rigid tube is then introduced in such a way that I almost reached the edge of the cavity in front of the housing opening. During the filling process it is removed then slowly the rigid tube of the housing opening guiding it transversely through the cavity. Can be filled thus the entire cavity in a uniform manner. In other panels of large building closure, especially doors  or wide gates, several such tubes can be introduced rigid, for example a battery of rigid tubes arranged in parallel, in a corresponding row of housing openings and they can be removed slowly again in a way correspondent.

As filler material is used preferably a bulk product that has been manufactured from of mineral materials stable against temperature, bad heat conductors and insensitive to fire. For example, him filler material is formed by molten minerals in the form loose. The bulk product formed in this way is presented preferably in the form of mineral fibers or mineral grains loose from molten ore. Examples are wool glass or spun rock loose state, glass fibers loose or loose glass balls obtained from glass swollen. The glass balls could also be construction hollow interior The same applies to mineral grains obtained from from other molten minerals.

The inorganic binder must offer Preferably substantially two advantages:

one.

 How inorganic binder, does not lead to combustion.

2.

It should endure quite high temperatures.

It is offered in this regard as a binder inorganic a soluble glass or a ceramic based glue. Such Adhesives exist in the market in the form of adhesives, masses of encapsulated or high temperature resistant coatings, which they consist of ceramic refractory materials, such such as silicon dioxide (SiO2), oxide of aluminum (Al 2 O 3), zirconium oxide (ZrO 2), oxide of magnesium (MgO), mica and aluminosilicates, which have been mixed with water or mixed with it before application. These pastes form when hardened adhesive bonds resistant to high temperatures

The use of glass is especially preferred soluble in the inorganic binder or directly as inorganic binder. In the known constructions of fire protection additional materials are introduced that yield moisture under heat. Soluble glass is such a material that yields water at quite high temperatures. Due to the use of soluble glass or other inorganic binders that yield moisture are They can save additional cooling media.

On the other hand, through the procedure according to the invention such means can also be introduced additional cooling in a simple and very homogeneous way inside the housing, more precisely inside the filler, for which purpose it is also expressly added, during or before of the introduction of the filling product formed by the filler material and inorganic binder, at least one other pouring additive or fluid containing moisture, such as water to give it up under the action of heat. This additive is turbidized. then with the filling product and thus introduced uniformly in the cavity

Another advantage of the procedure according to the invention is that when mineral fibers are used as material of filling, these mineral fibers are no longer arranged running mainly in one direction or arranged in layers, as usual in the state of the art, but they are located in a totally turbulized form inside the interior of the building closing panel for fire protection. Due at this complete turbulization, the glue of the filler material with the surrounding housing wall it will also work better than what has been demonstrated so far in the state of the art.

Therefore, the invention provides that, to manufacture fire protection door sheets or closure panels of similar building for fire protection, proceed to:

a) manufacture a closing panel housing of fire protection, for example a sheet housing door, and

b) introduce, especially insufflate or inject loose flame retardant wool or other into the housing cavity pourable or flowing filler material based on mineral material, especially loose mineral wool or bulk glass product swollen, which occurs, for example, in fibrous form and / or granulated

The introduction is eventually made with addition of an inorganic binder, such as especially glass soluble or sodium silicate, especially an inorganic binder that yield moisture under the action of temperature.

Instead of mixing the filling product and possibly other additives only during the introduction, it could also proceed so that a stored reserve of a flowing or pourable mixture. It could, for example, add loose mineral wool or granulated glass a inorganic powder which, with the addition of water or the addition of others solvents, act as binder. It is also possible to save in Store the filling product as a kind of pasta or in another flowing form, whose paste or other fluid could also present, for example, a foam former to form inside the cavity of the housing the advantageous cavities for the insulating action located within the fibrous material or other mineral material. How adding the binder is sufficient in principle that the individual particles of the filler material are moistened with the organic binder or that these, when injected into the cavity, circulate through a corresponding spray mist of the inorganic binder simultaneously introduced.

The larger the cavity to fill so much the greater the risk that the filler material is distributed from non-homogeneous form during introduction or drying or subsequent hardening. Therefore, it is planned according to a embodiment that the cavity to be filled is subdivided into Several sections.

For this reason and to achieve flatness required building closing panel, one execution Especially preferred of the invention provides that before insufflation or injection of the filler material, especially before assembling the housing, enter into the housing some rods, especially of insulating material, which then stick with the surfaces of the interior walls of the housing on both wide sides of the cavity. It is like this in conditions to control the thickness of the building closing panel and to prevent or at least very strongly reduce a deformation by Dent of wide surfaces during insufflation. The different cavities formed between these rods are filled Then with the filling material.

When these rods are used as spacers - in principle, spacers in other ways would also be possible - the door plate shape is reinforced. By means of these spacers the space in which the filling material is to be introduced is applied in a simple way to apply the material in a safe and uniform way, with the same density, for the entire height of the building closing panel. The glue introduced when insufflating the filling material has the advantage that the then introduced filling material could not drain down with the passage of time when opening and closing the door, such as could occur in the case of a loose wadding. Preferably, the building closure panel arrives for insufflation, or after insufflation, to a press in which it is pressed with the desired shape or maintained in the desired form, until the interior filling product is dry. The hardening or drying time can be influenced by selecting the organic binder or its
additives

Therefore, the building closing panel for Fire protection contains again after the process manufacturing - as in the state of the art - a plate flame retardant or a flame retardant mat of mineral material. Not left No loose bulk product inside the housing and material happens to have plate form again, only that they are no longer needed prefabricated plates or mats to fill the closing panel of building.

This is also an important advantage. for manufacturing, since, according to the state of the art, You have to order the plate and it has to be supplied somewhere, and especially for the type and size of desired building closure, as well as for thickness, width and desired height. With the invention these dimensions of the panel building closure are unimportant to enable a filler, since the manufacture of the filler plate or mat Filling takes place inside the cavity of the closing housing of the building panel with adaptation to the interior shape of is.

As material for reinforcements or spacers inside the cavity, that is, for example, the insulating rods previously mentioned, a material of Asbestos-free calcium silicate, such as sold, by For example, by Calsitherm Silikatbaustoffe GmbH, D-33175 Bad Lippspringe. They are very suitable materials with more than 95% silicate (CaO; MgO; Al_ {2} O_ {3}). Strips of such material have a resistance enough on one side and on the other side they can stick well and of chemically little aggressive form, so it can't be caused any corrosion on metal walls of the housing. These are the most important criteria to select materials from reinforcement rods

According to an embodiment example, the introduction of the loose filler material, for example fiber material mineral, is performed by injection, insufflation or other form of introduction under pressure, in a turbulizing or sparkling manner, to through a housing opening that is preferably on one of the narrow sides of the closure panel of building.

According to an embodiment of the panel of building closure for fire protection according to the invention, configured as a door leaf protection against fires, the opening are located on the bottom side.

In some doors of protection against fires, such as those that have already been manufactured by the applicant, there is a thick U-profile. The lower side is also located outside the optical appearance of a door leaf used according to your destiny, so that there you can practice without any optical impairment the housing opening for Enter the filling material. In each distance rod that  runs transversely to the direction of introduction through a hole is also made from the opening of the housing, for example approximately 30 mm in diameter, depending on the door leaf size. Through the housing opening and from these holes the rigid tube is then introduced until practically the end of the building closing panel opposite to the opening of the housing. The rigid tube is removed slowly and then the filling product is ejected. According to an example of embodiment, on the opposite side of the housing opening, by example on the upper front side or narrow side, they are arranged ventilation holes as a device ventilation for exhaust of insufflated air or other gases introduced as carrier fluid. As carrier fluid it serves preferably compressed air. According to another embodiment example, the carrier fluid escapes from the same end where it is also practiced the opening of the housing.

Instead of a rigid tube, it could be used also a flexible tube that could also move transversely to the direction of introduction to get so Better distribution It would also be imaginable to foresee a elongated introduction opening, for example leave entirely also open one of the front sides to admit a movement of the introduction device (i.e. for example of the rigid tube mentioned above) transversely to The introduction address. The rigid or flexible tube end provided with the ejection opening could be conducted like this also in the form of a helical line through the cavity to be Fill.

Preferably, the building closure panel It is closed on its three narrow sides, with the exception of ventilation openings Therefore, the housing cavity is preferably closed on all sides, except the opening of ventilation and housing opening.

Apart from the binder, with the procedure according to the invention other additives may also be introduced, by example water accumulation granules set in shape crystalline, for example based on aluminum hydroxide or containing the latter. The quantity of the respective materials to introduce or additive materials can be regulated - also by sectors - by means of a mixer head to be activated separately. Thus, zones can also be filled individually insulated inside the door in a way adapted to the requirements desired

How fillers enter consideration of pillable materials that meet the requirements of fire protection or other requirements imposed on isolating material. Bulk products based on glass materials, for example based on glass fibers or glass beads, in particular based on fibers and / or grains and swollen glass balls. Bulk products based on glass bloated are also recommended because of the general requirement of that building closures, such as protective doors against fires, they should not be too heavy.

Spacers arranged inside the panel, for example rods of insulating material, extend preferably in the direction of vertical arrangement. The spacer rods are, for example, fitted and provided of a cavity or recess in its retention soul, as it shown in the figures. Therefore, the spacer rods they have, for example, a double T profile. This has advantages fire protection techniques. Indeed, many insulating materials have a tendency to contract with heat shedding (for example, by loss of water). Without However, due to notching, slits of smooth path, for example on the boundary surface between spacers and insulating material, whose slits would influence negatively in the passage of heat. The distances between dosing rods can be chosen arbitrarily so that the surface of the door leaf offers a smooth appearance, for example at a distance of approximately 190 mm.

Therefore, with the procedure according to invention a building closure panel can be manufactured for fire protection, that is, for example, a sheet of fire protection door, with an outer casing that It is specially formed by sheet metal, hugging the housing to a filler formed from mineral materials with binder, preferably in plate form. This padding is formed by a turbulized or foamed mixture based on a material filled in granular or fibrous form made from molten materials and equipped with an inorganic binder, being able to other additives are also contained, although these do not have That be contained. For example, they may be additive contents that yield moisture under the action of heat. The interior space of the housing is propped up and / or preferably subdivided by spacers such as insulating rods and / or rods separation mentioned above. Separation rods they are preferably configured in the form of double T profiles. In the notched area thus formed, the filling material and this can be joined with the rods of separation by coupling by complementarity of form.

The device according to the invention for manufacturing the building closure panel for fire protection contains, apart from usual mechanisms to manufacture or provide a housing of the class mentioned at the beginning, especially a outer sheet metal housing, a reserve container for a bulk or flowing product, in which the material is contained filler containing grains or fibers made from Mineral materials, a mechanism of introduction with which the material can be insufflated or injected of filling in a cavity of the closing panel housing of building.

Preferably, a binder addition mechanism that adds a binder inorganic to the filler material to be introduced. It can dispense with this binder addition mechanism when the filler material contained in the reserve container is already mixed with an inorganic binder of this class. In addition, it is provided a feed pipe of filling material with the that the filler material can be conducted from the container Reserve until the introduction mechanism.

In a preferred embodiment the device It also contains an additive feed mechanism, a Dosing mechanism, an automatic process controller, a controllable mixer head and / or a delivery mechanism for carrier fluid

With the additive addition mechanism you can add, if necessary, other additives such as especially additives of the kind that yields moisture under the heat action. By means of the dosing mechanism you can adjust the quantity and flow rate of the filler material introducible and therefore the density of the Filling material. Through the controllable mixer head, You can adjust the amount of inorganic binder for addition to the filler material, as well as the amount of other additives. As a carrier fluid delivery mechanism, for example, A source of compressed air. With a carrier fluid such as air compressed - or, depending on the nature of the material to be introduced, also liquid carrier fluids - you can insufflate or inject into the housing of the building closure panel the filling product that is formed by filling material, inorganic binder and possibly additives.

Figure 12, a schematic view of another device for filling a building closure housing with insulating filler material.

Figure 1 shows a device for fill a building closing housing panel with material filling formed based on mineral materials. This device of filling is part of an installation to manufacture panels of building closure, such as a manufacturing facility fire protection door leaves. This installation does not it is represented in a particular way, but it contains usual metal machining devices to manufacture a housing of a fire protection door leaf as the one shown in figure 2 and explained in more detail ahead.

The filling device according to figure 1 comprises a reservoir of pourable or flowing product in the form of a silo 1 in which it is contained, as material of Filling, loose mineral wool 2 in spun state without binder. Fibrous mineral materials are designated by mineral wool, specially cast, such as glass wool, wool rock or basalt wool. Instead of mineral wool, they also enter consideration as filler material other mineral fibers existing in vertible state. In other embodiments the filler material is a granulate manufactured from, by for example, molten materials, for example a bulk product formed by swollen glass balls.

The filling device also has a feed pipe filling material in the form of a pipe 3 for mineral fiber that is provided with a mechanism 3a of pumping and blowing of compressed air that serves as a mechanism for carrier fluid supply. Pipe 3 for mineral fiber flows into a rigid tube 4 to introduce the fiber material Mineral on a door leaf. In the rigid tube 4 it opens also a supply pipe that is connected by the other end to a container 5 for inorganic binder. He container 5 is filled with inorganic binder in the form of sodium silicate or soluble glass 6 in a liquid state or dissolved.

In the following you will find more details, with help of figures 2 to 5, on the housing 7 of a sheet of fire protection door manufactured in the installation of manufacture of door leaves and enabled to be filled by middle of the filling device. The housing 7 is a housing internally hollow sheet metal. Crosswise through the sheet metal housing are arranged rods 8 for support the wide sides of metal and to separate fields of filling the cavity inside the sheet metal housing 7. In the exemplary embodiment shown in Figures 2 to 6, the rods 8 run horizontally in the arrangement of Door leaf destination. As depicted in Figure 3, the upper front side 9 is provided with several openings of ventilation 10. As can be seen in Figure 4, each rod 8 is provided, in the center, with an opening 11 so that it passes to its through the rigid tube 4. On the lower front side the housing 7 sheet metal has a closure in the form of a closure profile lower 12 U-shaped, which is also provided with the central opening 11 so that the rigid tube 4 passes through it. Except for the ventilation openings 10 and the opening 11 of the closing profile 12, the cavity to be filled formed in the housing 7 It is closed on all sides. As can be seen in the Figure 6, the rigid tube 4 extends transversely through all openings 11 to near the upper end of the housing 7. By means of the pumping and air blowing mechanism 3a compressed now blows loose mineral wool inside of the housing 7 through the rigid tube 4 and at the same time the sodium silicate or soluble glass 6. Compressed air escapes through the ventilation openings, as suggested in 14. Due to the insufflation carried out under pressure they become strongly turbid the individual mineral fibers. These are wetted with the soluble glass 6 and thus form a turbilized mass that sticks With Herself. As implied in Figure 6 by means of a arrow, the rigid tube is slowly pulled down from the housing, so that all the filling fields separated by the rods 8 are successively filled by the filling product 13 formed by mineral fiber wool with binder. Then the housing 7 is taken to a press, where the process takes place hardening of the filling product. After drying and hardening of the inorganic binder (soluble glass 6), the filling product 13 is presented as a mat inside of the housing cavity 7.

Another example of realization of a fire protection door leaf 16 filled with the filling product 13. In this door they are arranged 8 'rods that act as spacers and separations and that do not extend in the horizontal direction, but in the direction  Vertical of fire protection door leaf 16. In the lower closure profile 12 'U-shaped are several openings 22 for introducing filler material, at the rate of one opening 22 for each filling field separated by the rods 8 '. As can be seen in figures 9 and 10, the housing metal 19 to be filled (see also figure 8) is formed, among other elements, by metal sheets 20 and 21 that they form the wide sides and that are joined to each other by means of the 8 'rods. The 8 'rods consist of calcium silicate, they have a double T profile with notches 23 and are glued with the respective metal plates 21 and 20. The metal plates 21, 20 may be attached to each other by the edge side, above and on the side, as is known from EP 0 733 149 B1 or WO96 / 07004.

The filling of the housing 19 represented in Figures 7 to 11 are made by successively filling each of the filling fields separated by the 8 'rods with the help of individual rigid tube of the filling device represented in Figure 1 or with the aid of a set of several rigid tubes 4 parallel to each other that can be introduced and extracted simultaneously through the openings 22 of the closing profile 12 '.

A device of filled with this set of rigid tubes 4. The device refilling presents a reserve container 24 for material insulating and flame retardant based on mineral material, which is filled here with grains and / or swollen glass fibers as filling material 25. This reserve container 24 has a metering valve 26 as a metering mechanism for dosing the filling material 25. In a pipe 28 for the pourable insulating product circulates a carrier fluid (for example, compressed air) placed under pressure by means of a source 27 of a pressurized medium that serves as a fluid delivery mechanism carrier, such that said carrier fluid drags the filling material 25 dosed from the reservoir container 24 through the metering valve 26 and conducts it through the pipe 28 to a controllable mixing head 31. A connecting pipe with the container 5 for inorganic binder with the silicate of sodium or the soluble glass 6 contained in it in a liquid state or dissolved serves as an additional flow feed to the head controllable mixer 31. The term soluble glass designates especially vitreous (potassium or sodium) silicates, soluble in water, solidified from the foundry mass, or its viscous aqueous solutions with the chemical composition Me_ {2} O \ cdotnSiO2, where Me means sodium or potassium, but also lithium and NH4, where n = 2 ... 4. Other pipe power to the controllable mixer head 31 is connected by the other end with a container 29 for additive 30, such as especially granulated aluminum hydroxide.

The output of the controllable mixer head 31 flows into a controllable distributor head 32 that drives the mix in form the mixing head 31 to the various tubes rigid 4 to fill the building closure panel 33 for fire protection. An automatic controller 34 of process serves to adjust and control the different mechanisms 26, 27, 31, 32.
