Description

Method of use

This invention relates to a building cladding system with fire protection and sound protection properties, whereby one grid consists of mutually parallel basic profiles, which are assigned a means for applying to the grid and mutually parallel load-bearing profiles, which are placed in front of the basic profiles and on they are attached, and in which the plate elements are placed in front of the load-bearing profiles and are fixed to them, and plate material in the fire protection version is also foreseen.

In one already known building cladding system (DE prospectus "Knauf Gipsplatten-Deckensysteme D11", January 1997) of this type, the elements of the building board panels in the fire protection design are placed in front of the load-bearing profiles, which directly abut on the load-bearing profiles. Construction panels in the fire protection design are, according to their design (type), a completely closed structure with a smooth surface of the panel placed towards the outside. With this construction cladding system, a strip of sheet material in the fire protection design is assigned to the opening between the adjacent building panels in the fire protection design, which rests on the back side of the building panel in the fire protection design and has a distance from both arranged load-bearing profiles. With this system, the properties related to fire protection are satisfactory, while the properties of sound protection are not satisfactory.

The task of this invention is to construct a building cladding system of the kind mentioned in the introduction, where the sound protection properties are also improved while maintaining satisfactory fire protection properties. The building cladding system constructed according to the new proposals, which should solve the task, is indicated by the fact that the load-bearing profiles on the outside are each covered with pieces of plate material in a fire-resistant design and that between all the load-bearing profiles, extending from the load-bearing profile to of the load-bearing profile, they place strips of plate material in the fire protection design in front of the basic profiles, whereby the pieces of plate material in the fire protection design are placed on the load-bearing profiles, and the strips of plate material in the fire protection design on the base profiles, and the panel elements placed in front of the load-bearing profiles are perforated plates with sound insulation.

In the building cladding system according to this invention, the sound protection properties are improved by means of perforated panels placed in front, i.e. they become satisfactory, whereby the perforated panels, regardless of the area of the load-bearing profiles, are on the back side without sound insulation. The sheet material in the fire protection version wraps the load-bearing profiles and is placed from the back in relation to the basic profiles. The building height of the building cladding system with grid formwork is kept relatively low and does not increase significantly. Only in the area of load-bearing profiles, the sheathing is stacked in layers with plate material in a fire-resistant version and a perforated plate with sound insulation. Perforated panels improve the desired effect of sound insulation, even though they are placed behind the load-bearing profiles. The sheet material in the fire protection version does not pass straight, looking along the basic profile, but turns around the load-bearing profiles or is guided around them. The space between the load-bearing profiles is used.

It is particularly expedient and convenient to place a layer of mineral fibers between the strips of panel material in the fire protection version and perforated panels with sound insulation. The layer of mineral fibers we receive serves as fire protection, but also has a sound-insulating effect. This layer uses the hollow space between the load-bearing profiles and improves the fire protection properties, without increasing the building height of the formwork. The layer of mineral fibers is "wool" and usually rock wool.

It is especially expedient and convenient in this case, if the strips of plate material in the fire protection version and the layers of mineral fibers form a glued joint. This joint simplifies the assembly of the building cladding system. The sheet material in the fire protection version is placed from the back side in relation to the grid, and the layer of mineral fibers from the front side, that is, towards the visible side of the building cladding system. The connecting plate is already a well-known building element and here it is installed in a new way.

It is especially expedient and convenient, then, if the strips of sheet material in the fire protection design, also in connection with layers of mineral fibers, have cutting edges with a cutting structure along the longitudinal edges. Strips as well as connecting strips are made by cutting large plates, as is done for other purposes. Also here, already existing or manufactured building elements are installed in a completely new way.

The building cladding system is placed on the rough-built rock in such a way that it can be easily dismantled. A rock of rough construction is, for example, a vertical wall of a room or, more appropriately, the ceiling of a room. The building cladding system is hung on the ceiling of the room of rough construction and is designated as the lower panel. Grid installation elements made as suspension elements have been known for a long time. With the grid, the basic profiles and supporting profiles are connected to each other at each point of intersection. As a rule, basic profiles and load-bearing profiles are made of metal, and are rectangular in cross-section and most often form a single U in cross-section, whereby this U can end freely at the ends of the legs or have curves (so-called C-profile).

It is particularly expedient and convenient if a layer of fleece is provided on the side of the perforated panel with sound insulation facing the grid. The fleece layer serves as protection against moisture and covers the openings of the perforated panel, without jeopardizing the sound protection properties. For example, a fleece layer is provided in conjunction with a perforated panel with sound insulation.

It is particularly expedient and convenient to implement this new invention if the grid between the basic profiles assigned to the means for applying to the grid from the means for applying to the grid has free additional basic profiles, on which the strips of plate material in the fire protection design are also fixed. These additional basic profiles, which are also fixed to the load-bearing profiles, are used to stiffen the strips of sheet material in the fire protection design, which, especially if coated, have a tendency to sag in the event of a fire.

It is expedient and convenient that there are free spaces between the load-bearing profiles on the perforated panel with sound insulation facing the grid, i.e. on the side of the strips of panel material in the fire protection version facing the perforated panel, in which the cooling/heating devices are placed. Cooling/heating devices, which for example can be thermal heating pipes or electric surface heating elements, serve to improve the building cladding system and deliver heat or cooling energy into the space through the openings of the perforated panel with sound insulation.

Furthermore, it is particularly expedient and appropriate if the pieces of fire-protective plate material covering one of the load-bearing profiles are made as a transverse strip and two strips perpendicular to it along the arm, and each strip along the arm rests diagonally on the transverse strip, and that the strips on both sides coated, whereby this coating passes without interruption along the oblique connection of the transverse strip with the strips along the arms. Already known (DE-Prospekt "Knauf Design-Decken D19, November 1996) building elements are used here. Both strips along the arms and the transverse strip are further flat-shaped, where they are separated by a V-cut, which only allows cladding at the top of the V. In the built-in state, the oblique adjacent surfaces are glued to each other.

It is especially expedient and convenient if the strips of sheet material in the fire protection design are made of coated construction boards. The strips then have the same properties as the pieces of sheet material in the fire protection version, which cover the load-bearing profiles. Clad building panels are, for example, plasterboard panels or panels coated with glass fiber layers. The fire protection panel material of the building cladding system according to the present invention can be, for example, also a cellulose fiber board or a board bonded with cement.

Furthermore, it is particularly expedient and convenient that the screws, which fasten the strips of sheet material in the fire protection version to the basic profiles, are placed with the heads on the passages through the layer of mineral fibers. Passages are made by tearing the layer of mineral fibers, when screws are twisted with an electric screwdriver through the previously undamaged layer of mineral fibers.

Furthermore, it is especially expedient and appropriate if a wide edge field is additionally provided parallel to the load-bearing profiles or basic profiles, over which the grid extends and where a double layer of plate fire protection material is placed in front of the load-bearing profiles. This additional edge area is without special sound insulation measures, that means no perforated panel. Strips of plate material and pieces of plate material with which they are covered are also omitted, because a double layer of fire protection material is provided for fire protection. The additional edge area without sound insulation on the building lining system serves to regulate the overall effect of sound insulation.

A recommended embodiment of this invention is shown in the drawings, in which

Fig. 1 represents the design of the building cladding system with fire protection and sound insulation properties,

Fig. 2 represents a cross-section along the line II-II from Fig. 1 in an enlarged scale compared to Fig. 1, and

Fig. 3 represents a further section of the building cladding system from Fig. 1 with an additional edge area.

According to the drawing, the building lining system is executed as a suspended lower blanket, suspended on the horizontal blanket of the room of rough construction, which is not shown in Fig. 1, and covered by the vertical walls of room 1, of which only two are shown. The building cladding system has a metal grid 2, which consists of basic profiles 3, 4 and load-bearing profiles 5. The basic profiles 3, 4 and load-bearing profiles 5 are the same in cross-section and made in a C-shape, where they form a U-bar, two U-arm and two C-bends. Every other basic profile 3 is covered with suspension elements for installing the grid 6, which lead to the blanket of raw construction. At each intersection of one of the basic profiles 3, 4 with one of the load-bearing profiles 5, a connecting element 7 is placed for connecting the profiles. The load-bearing profiles 5 rest with the free ends of the U-arm 6, i.e. with parts of the C-curvature on the U-bar of the basic profiles.

Each load-bearing profile 5 has along its length on the total outer side, that means on both U-arms and on the U-crossbar, a lining 8 made of plate fire protection material, which is composed of three pieces 9, 10, 11. Pieces 9,10 which they correspond to each U-leg, and piece 11 touches the U-bar of the prophylaxis at the chamfer 12, and they are glued to each other along the entire chamfer. The lining 8 is attached to the supporting profile 5 using screws that are not shown. Between every two adjacent load-bearing profiles 5, a strip 13 made of plate material in a fireproof version is intended to be placed, which on one side touches the lining 8 of one load-bearing profile, and on the other side the lining of another profile, more precisely pieces 9 and 10. Screws 14 are fastened through the strips 13 into the U-bars of the basic profiles 3, 4, on which the strips rest.

Each strip 13 is provided in connection with one layer of mineral fibers 15, which also extends between the coverings 8 of two adjacent load-bearing profiles 5. The layer of mineral fibers 15 fills, for example, the entire hollow space between the load-bearing profiles or leaves the side opposite to the strip 13 free space 16 in which cooling/heating devices 17 are placed. Where the screws 14 are provided, the layer of mineral fibers 15 has passages 25, through which the screws are passed during assembly. Next to the lining 8 of the supporting profiles 5, a thin layer of fleece 18 is placed, which passes over the entire building lining system, and is provided in connection with the perforated sound insulation board 19, which has openings 20.

Fig. 3 shows the blanket in the raw version 21, on which the building cladding system is suspended using elements 6 for placing the grid. The building cladding system is extended along the outer longitudinal dimension for a wide edge field 22, which extends widthwise from the wall of the room 1 over two load-bearing profiles 5. This edge area 22 is highlighted by a double layer 23 of fire-resistant sheet material, which is placed on U-bars load-bearing profiles 5, to which it is attached with screws 24 and composed of two strips of plates.
