Description

The technical solution concerns an inter-window panel for reconstruction of prefabricated houses.

BACKGROUND OF THE INVENTION

In the past, in a number of prefabricated houses, windows were assembled into continuous horizontal strips, where the individual windows in this stripe were separated only by a so-called lightweight inter-window insert, whose construction, however, no longer complies with applicable heat, hygiene and fire standards. heat from the interior, does not insulate against external noise, and has insufficient fire resistance.

I 10 Of course, the refurbishment of the described types of prefabricated houses involves the installation of improved t windows, which are sufficient on the market, but the end result of the refurbishment is often devalued by the use of the original window inserts, which sometimes only additionally insulate.

Another known solution is to replace the light inter-window insert with a sandwich PUR board, which, however, represents only a marginal improvement in thermal resistance, has even worse noise attenuation, while at a position between adjacent apartment windows or use.

In essence, only the procedure in which the space between the windows is bricked in a known manner satisfies the present requirements. The disadvantage is that the bracing and subsequent plastering of the space between the windows is relatively time-consuming, and these so-called wet processes greatly annoy the users of the reconstructed building, especially in residential buildings.

The aim of the solution is to design an inter-window panel which could be easily manufactured as a prefabricated part outside the reconstructed building, which would allow a quick installation on the site of the reconstruction, while at the same time meeting both thermal, hygienic and fire standards.

The essence of the technical solution

This object is achieved by an inter-window panel for the reconstruction of prefabricated houses, according to the technical solution, which consists in that it consists of a wooden frame, which is clad with extruded cement-bonded particle boards on the outside and inside and filled with mineral wool.

30 The window panel according to the technical solution complies with current thermal, hygienic and fire regulations. It can be easily manufactured as a prefabricated part outside the reconstructed building. Allows quick installation on site. It is therefore an optimal substitute for the previously used unsuitable lightweight window liner.

To increase the torsional resistance, the wooden frame is made of glued beams.

According to a preferred embodiment, the wooden frame is circumferentially covered with pressed cement-bonded particleboards.

To increase the fire resistance, the timber frame may be circumferentially encased with non-flammable molded lime boards, or alternatively at least one side of the timber frame and the pressed cement-bonded particleboard may be embedded with a non-flammable molded lime board in the shape of strip.

In another preferred embodiment, a vapor barrier is interposed on the interior side between the pressed cement bonded particleboard and the mineral wool.

The final finish of the interior may consist in attaching a plasterboard to the pressed cement-bonded particleboard.

To further increase the fire resistance, a foaming tape is placed on the non-flammable pressed lime-silicate boards around the perimeter of the window between the windows, and the joint is filled with fire mounting foam.

BRIEF DESCRIPTION OF THE DRAWINGS

The technical solution will be described in more detail with reference to the drawings, in which Fig. 1 shows a panel house with inter-window panels, and Figs. 2 to 4 show cross-sectional examples of an inter-window panel according to the invention. For the sake of simplicity, the cuts only show the upper part of the inter-window panel and part of the perimeter panel of the reconstructed house, including the assembly joint design.

Examples

Fig. 1 schematically shows the front side of a panel house, on which the perimeter panels 14 and the windows 13 are visible, between which the window panels 12 are arranged.

A first exemplary embodiment of the window panel 12 is shown in Fig. 2 and consists of a rectangular wooden frame 1. To increase the torsional resistance, the wooden frame 1 is made of glued prisms. The wooden frame 1 is covered with pressed cement-bonded particleboards 3 from the outside and inside and the inner space is filled with mineral wool 5.

The timber frame 1 is also circumscribed by molded cement-bonded particleboards 3.

On the interior side, a vapor barrier 4 is inserted between the pressed cement-bonded particleboard 3 and the mineral wool 5, the purpose of which is to prevent water vapor from entering the mineral wool 5, which would impair the insulating properties of the mineral wool 5.

The inter-window panel 12 of the above-described embodiment is already ready for the construction. The annular panel 12 is anchored to the peripheral panel 14 at four points by means of anchors (not shown). An expansion tape is inserted into the gap between the perimeter panel 14 and the window panel 12 and the space is filled with mounting foam 7, which is covered on the inside and outside with acrylic sealant 6.

After completion of the assembly, conventional thermal insulation systems or finishes are applied from outside to the panel 12.

The plasterboard 2 is attached from the interior side to the panel 12.

Figures 3 and 4 show embodiments of an inter-window panel 12 for use in locations with the desired increased fire resistance. These embodiments differ from the embodiment of Fig. 2 in that the timber frame 1 is circumferentially encased with non-combustible molded lime slabs 11.

The embodiment of Fig. 3 also has on the exterior side between the timber frame I and the outer molded cement-bonded particleboard 3 also embedded a non-flammable molded calcium silicate sheet 11 having a strip shape overlapping the outer face of the timber frame 1. The window panel 12 thus treated has fire resistance El 30.

In addition, the embodiment of FIG. 4 has a non-flammable molded calcium carbonate sheet 11 having a strip shape overlapping the inner face of the timber frame 1 on the interior side between the timber frame 1 and the inner molded cement-bonded particle board 3. El 60.

Both the window panel 12 of FIGS. 3 and 4 have a commonly known foaming tape 10 mounted around the entire outer periphery, which in the event of a fire due to heat increases its volume several times to prevent the fire spreading through the peripheral panel around the window.

3 and 4 is similar to the embodiment of FIG. 2 described above. The only difference is that the non-flammable mounting foam 7 is covered on the inside and outside with mastic-based sealant 9.
