Description

DESCRIPTION

Firebreak device.

The present invention relates to a fireproof device.

Currently, fireproof devices are known, such as, for example, doors or fixed walls which are formed by a plurality of modular panels coupled together. This type of fireproof devices is particularly suitable for industrial buildings, to carry out the closure of large openings, typically several meters in length and height.

The modular panels that make up the known devices are coupled together by means of coupling elements of the male-female type. These couplings represent a point of criticality in the fire structure, in the sense that they constitute discontinuities in the structure of the fireproofing device that can let fumes, heat or flames pass through.

For this reason, it is convenient to make couplings that define a blocked path between two modular panels. For example, fire partitions are known in which male-female couplings comprise two male elements on one side and two female elements capable of receiving the two male elements on the other side. An example of this type of male-female coupling is shown in Figure 1.

DE 9013911.9 discloses a fireproof device, according to the preamble of claim 1 and as indicated above, comprising a further coupling part disposed between the two coupling parts, as shown in Figure 1 of the present application for patent. The central coupling part shown in DE 9013911.9 comprises a male element on the same side as the male elements of the remaining coupling parts and, vice versa, a female element on the same side as the female elements of the two parts of coupling remaining. However, this does not meet the requirements of this field of technology, since it does not confer perfect structural continuity to the fireproof device.

Document FR 2 976 302 discloses a counterfire device similar to that described in DE 9013911.9.

These two documents of the known art only admit the possibility of presenting male elements on one side and female elements on the other side. They do not allow the possibility of presenting a male central element with the female elements of the two remaining coupling parts, and vice versa.

The known devices do not offer optimum reliability in these coupling areas. In case of fire, these structures may not be able to sufficiently block smoke, heat transmission or flames.

In addition, a further disadvantage of the known devices is that they are not capable of acoustically isolating the rooms. However, this aspect, although secondary when a fire develops, is perceived in the absence of a fire, when the internal activities of a building are carried out normally. Therefore, an object of the present invention is to provide a fireproof device equipped with modular panels that do not allow the passage of smoke, heat or flames in case of fire.

Another object of the invention is to provide a fireproof device equipped with modular panels having a continuous structure, even between two successive panels.

Another object of the present invention is to provide a fireproofing device that also allows to improve the acoustic insulation between the individual rooms.

These and other objects are achieved by a fireproof device made according to the technical teachings of the appended claims.

The concept underlying the present invention is to provide a fire protection device with improved male-female couplings and, in particular, in which the couplings are provided, in addition to known coupling elements, with an additional coupling part located in a central area within the thickness of the panels that make up the fireproofing device and in which the central part of the male part comprises a female element and, reciprocally, the central part of the female part comprises a male element suitable for coupling with the element female of the central part of the male part.

Other features and advantages of the invention will become apparent from the description of a form of preferred, but not exclusive, embodiment of the fire device, which is presented herein for explanatory purposes only, and is therefore not limiting, in the accompanying drawings, in which:

Figure 1 is a cross-sectional view of a coupling area of two successive modular panels of a known fire-resistant device;

Figure 2 is a cross-sectional view of a coupling area of two successive modular panels of a first embodiment of the fire-resistant device according to the invention;

Figure 3 is a cross-sectional view of a coupling area of two successive modular panels of a second embodiment of the fire protection device according to the invention.

Figure 2 shows a detail of a first embodiment of the fire protection device according to the invention. In particular, FIG. 2 shows a coupling zone 1 between two successive modular panels 2, 3 of the fire protection device.

It should be noted that the fire protection device according to the invention can be a mobile device, such as a door, or a fixed device, such as a wall.

The fireproofing device comprises a first modular panel 2 formed by a front surface and a rear surface, equipped with a coupling element 4, and at least a second modular panel 3 provided with at least one coupling counter-element 5 capable of cooperating with the coupling element 4.

Generally, the modular panels 2, 3 are made of a composite material that is a poor conductor of heat or a heat reflector, such as, for example, treated mineral wools (stone, fiberglass, wood wool or others) , and have a height comprised between 300 and 10000 mm (i.e., 10 m) and a thickness S1 in general comprised between 60 and 200 mm.

The coupling element 4 comprises, in turn, at least one base plane 40, at least one coupling element 41 protruding from the base plane 40, while the coupling counter-element 5 comprises at least one counter-plane of base 50 and at least one countertop 51 recessed in the base counter-plane 50 to receive the coupling element 41 of the coupling element 4. It should be noted that the base plane 40 and the base counter-plane 50 are adequately parallel to each other and are inclined with respect to the front surface 20, 30 and to the rear surfaces 21, 31 of their respective modular panels 2, 3, preferably perpendicular to said front and rear surfaces. The coupling element 4 comprises at least one central coupling part 42, arranged in a central section of the coupling element 4 with respect to the front surface 20 and to the rear surface 21 of the first modular element 2, and separated from the coupling element 41 through at least one section 43 of the base plane 40, and the coupling counter-element 5 comprises at least one central coupling counterpart 52 arranged in a central section of the coupling counter-element 5 with respect to the front wall 30 and the wall the rear side 31 of the second modular panel 3 and able to interact with the central coupling part 42 of the coupling element 4, the central coupling counterpart 52 being separated from the counter-seat 51 by at least one section 53 of the base counter-plane 50.

The (against) coupling element protruding from the (against) base surface means, in the present document, a male coupling element, while (counter) seating recessed in the (against) base surface means, in the present memory, a female coupling element.

The central coupling part 42 and the central coupling counterpart 52 possibly comprise a male element or a female element (and a female counter-element or a male counter-element, capable of interacting with the central part element). The presence of the central (counter) part 42, 52 makes it possible to create an additional obstacle in the potential heat path by the fire-resistant device 1.

According to the present invention, the central coupling part 42 comprises at least one seat 42 recessed in the base plane 40 of the coupling element 4, and the central coupling counterpart 52 comprises at least one coupling element 52 projecting from the counter base 50 and is apt to be inserted in the seat 42 of the central coupling part 42.

The presence of the seat 42 located in the base plane 40 of the coupling element 4, which at the same time already comprises at least one coupling element 41, makes it possible to add a female accessory to said male coupling element 4, and vice versa. In this way, an interpenetration of the coupling element 4 and of the coupling counter-element 5 can be realized, thereby improving the continuity of the structure of the fire-resistant device.

In the example shown in FIG. 2, the coupling elements 41 and the counterparts 51, as well as the seats 42 and the coupling counter-element 52, have a cross-section with a substantially trapezoidal shape. However, it is possible to present another type of shape, provided that a clogged path can be created between two modular panels 2, 3.

Advantageously, the coupling element 4 comprises two coupling elements 41, and the coupling counter-element 5 comprises two corresponding counter-elements 51, as shown in the attached figures.

Still more advantageously, the seat 42 of the coupling element 4 is disposed in an intermediate position between the two coupling elements 41, and the coupling counter-element 52 of the coupling counter-element 5 is disposed at an intermediate position between the two contra-seats 51. As shown in Figure 2, it is preferred that the seat 42 of the coupling element 4 be separated from both coupling elements 41 by corresponding sections 43 of the base plane 40, and that the coupling counter-element 52 of the coupling counter-element 5 it is separated from both contra-sections 51 by corresponding sections 53 of the base counter-plane 50.

It should be noted that in the example shown, the coupling element 4 comprises a single base plane 40, from which the coupling elements 41 protrude. However, a coupling element may be provided which has two base planes, each one per side with respect to the central coupling part 42, which do not coincide with each other but are parallel. In other words, the coupling element could have two base planes at different heights. In fact, the same considerations also apply with respect to the coupling counter-element 5.

In the examples shown in Figures 2 and 3, the seat 42 of the coupling element 4 and the coupling counter-element 52 of the coupling counter-element 5 have a thickness S2, preferably comprised between 30% and 60% of the thickness S1 of the modular panels 2, 3, preferably between 40% and 55% of the thickness S1 of the modular panels 2, 3. Said thickness S2 of the seat 42 and its corresponding coupling counter-element 52 is measured in its bases, i.e. in the base plane 40 and in the base 50 backplane, respectively.

It should be noted that other embodiments can be carried out in which the thickness S2 can have any value. It is also possible, for example, for the presence of two or more seats 42 or coupling elements 52 between the coupling elements 41 and the seats 51.

As shown in Figure 2, the coupling element 4 advantageously comprises at least one edge seat 44 recessed with respect to the base plane 40 and disposed between a coupling element 41 and an edge 45 of the coupling element 4, and the coupling counter-element 5 comprises at least one edge coupling counter-element 54 protruding from the base counter-plane 50 and disposed between a counter-coupling 51 and an edge 55 of the coupling counter-element 5.

Said edges 44, 55 of the (against) coupling element 4, 5 coincide with a section of the front surfaces 20, 30 and of the rear surfaces 21, 31 of the modular panels 2, 3.

In the example of figure 2, the coupling element 4 comprises two edge seats 44, located directly side by side in their respective coupling element 41, that is, no section of the base plane 40 is presented between edge seats 44 and coupling elements 41. In the same way, the coupling counter-element 5 comprises two edge coupling elements 54 located directly side by side in the seats 51, without any section of the base plate 50 interposed between yes.

Advantageously, it is indicated that the coupling counter-element 52 of the coupling counter-element 5 has a length L1, in a direction perpendicular to the base counter-plane 50, less than or equal to the length L2, in a direction perpendicular to the base counter-plane. 50, of the edge coupling counter-element 54. In this way, the coupling counter-element 52 is confined to the space occupied by the coupling counter-element 5, which makes it possible to limit the remains as well as to protect said coupling counter-element 52 while the panels are transported. Modular 3, up to the assembly of the fire device 1.

It should also be noted that, preferably, the length L2 of the edge engaging counter element 54 is substantially equal to the length of the edge seat 44, i.e. the distance between the base plane 40 and the bottom of the edge seat 44. In this way, the labyrinth created by the cross section of the device 1 is even more efficient in preventing fumes from passing through it.

The coupling element 4 and the coupling counter-element 5 of the device according to the invention are more compact and provide a better continuity in the structure of the device between the modular panels 2, 3 that compose it.

The operation of the invention is as follows.

The first task consists in preparing a plurality of modular panels 2, 3 provided with coupling elements 4 and / or with coupling counter-elements 5, which are reciprocally arranged to assemble the modular panels 2, 3 together.

Next, said panels 2, 3, once assembled, are coupled and raised in a building.

In the event of a fire, the continuous structure of the fire device makes it possible to effectively block the flames, fumes and heat. In fact, the only discontinuities that exist are the cracks in each coupling zone 1, said cracks being thin and presenting a clogged path. Figure 3 shows a variant of the fire protection device according to the present invention. The elements that are common to the first embodiment described above will not be described again and will be identified by the same reference numbers, to which an apostrophe has been added.

In the variant shown in FIG. 3, the coupling element 4 'also comprises an interleaved seat 46' and the coupling counter-element 5 'also comprises an interposed counter-support 56'. Said interleaved seat 46 'and interleaved counterpart 56' are apt to cooperate with each other in order to form a space 6 'in which an interleaved element 7' can be inserted, once the modular panels 2 ', 3' are assembled each.

Preferably, the interleaved seat 46 'and the interleaved counterpart 56' have a rectangular cross section, as well as the interleaved element 7 'designed to be inserted into the space 6'.

Said interleaved and interspersed counter-seat 46 ', 56' are located in a position which is substantially central with respect to the thickness S'1 of the modular panels 2 ', 3', therefore, in correspondence with the seat 42 'and with the coupling counter element 52 ', the latter is shown in an intermediate position with respect to the coupling elements 41' and the counter-forces 51 ', respectively.

It is advantageously indicated that the coupling element 4 'and the coupling counter-element 5' have a symmetrical cross section with respect to a central axis parallel to the front and rear surfaces of the modular panels 2 ', 3'.

Obviously, it is convenient to indicate that the fire protection device can also be equipped with an interleaved element 7 'inserted in the interposed space 6'. Said interleaved element 7 ', also made of a material that has poor thermal conductivity, in addition to improving the fire performance of the device, also stops the sound waves, which confers acoustic insulation properties to the fireproofing device.
