Description

The The invention relates to a thermal protection arrangement for building ceilings, especially cellar ceiling, with the building ceiling on its underside is uneven and / or has installations.

at thermal insulation measures are at buildings adequate heat protection measures on building ceilings, especially basement ceilings, important. For cellar ceilings offers an insulation from the cold bottom, so from the basement, because there is neither one new floor construction in existing residential areas, still a complex seal in terms of a possible Dew point shift necessary is. Especially for subsequent insulation work in the building stock is an insulation of Floor ceilings, especially the basement ceiling, only of the not committed underside with reasonable effort possible and useful.

Lots Houses The years of construction 1950 to 1970 have uninhibited massive cellar ceilings. On the massive basement ceiling is usually a footfall sound insulation and a screed layer on which then the finished floor is laid. Corresponding Bad are the insulation properties this ceiling construction. To cold feet on the ground floor of such buildings and corresponding heat losses To avoid it, it is therefore known to place insulation boards immediately below to install the basement ceiling. The problem is usually that the clear height the basement rooms is limited and therefore the insulating layer preferably low strength should have. In itself rigid insulation boards are preferred directly with a Special adhesive glued under the concrete ceiling.

For older ceiling constructions, For example, so-called cap ceilings, as in the years of construction 1900 often executed until 1960 The ceiling base is through the arched cap wall with this known Dämmmethode not to edit. Furthermore, it is difficult to cover buildings at the bottom are covered with installation cables, effectively with rigid foam insulation boards to provide.

For such problem cases Although it is known by a suspended ceiling construction, for example made of solid surface boards a cavity between uneven underside the building ceiling and the newly inserted suspended Ceiling to create with a blowing insulation, such as cellulose insulation blown out without joints. A disadvantage of this method is that known Einblasdämmstoffe only a medium heat conduction group from about 040 to 050 and thus provide appropriate insulation thicknesses are. Furthermore, the substructure for the suspended ceiling as well as the material consumes the suspended ceiling, For example, plasterboard or mineral fiber board turn Construction height. Overall, these known constructions are therefore often very common low basements or only under a corresponding impairment the usability of the basement rooms usable.

Corresponding It is an object of the invention to provide a thermal insulation arrangement for building ceilings, those on an uneven and / or installed base the building ceiling can be attached, with the lowest possible build-up strength at the same time big Insulation effect to achieve.

Is solved this task with a thermal protection arrangement according to claim 1.

Thereby, that under the deepest points of the uneven and / or with installations provided ceiling base a self-contained high performance insulation panel is arranged, with the between the ceiling bottom and the Hochleistungsdämmplatte clamped cavity with a blow-in insulation and / or a flexible and compressible mat insulation filled out is, as the visible surface for the newly created ceiling underside suitable high-performance insulation board as close as possible to the existing building ceiling brought. On time-consuming cutouts and / or recesses can be dispensed with. Due to the closed position of a Hochleistungsdämmplatte will be a high thermal insulation too achieved at relatively low insulation board thickness. The overall construction of the heat protection arrangement is correspondingly low. To the between the high performance insulation board and the uneven ceiling bottom resulting cavity also for the insulation to be able to use effectively this is with blowing insulation and / or a flexible, compressible matte insulating material filled. In the episode will be a for the low construction height and the uneven underside of the existing building ceiling achieves optimum thermal insulation.

In order to be able to easily control the horizontal orientation of the high-performance insulating panels to be provided on the underside of the ceiling, a substructure is provided for the high-performance insulating panels, which is fixed by means of leveling screws on the ceiling underside and oriented horizontally. By means of the leveling screws, the horizontal alignment can be achieved with little effort. In order to keep the overall strength of the heat protection arrangement low, the substructure is formed of wooden strips with a thickness of 1.5 cm to 4.0 cm, preferably about 2 cm. In a Kellerkappendecke the preferably 2 cm thick wooden strips across the Steel girders, between which the cap wall is inserted, are mounted under the ceiling. The wooden slats should be fastened by means of leveling screws in the cap walling.

If the high performance insulation board a heat conducting group (WLG) of ≤ 030 and a strength of 2 cm to 6 cm, preferably 4 cm, is sufficient for residential purposes basic insulation of building ceiling reached. With a floor over a cellar can thus an unpleasant foot cold in the living room be avoided. Preferably, there is the high-performance insulating panel made of expanded polystyrene (EPS), rigid polyurethane foam (PUR) or phenolic rigid foam (PF).

Around a pleasing view of insulated with the thermal insulation arrangement building ceiling to reach from the bottom is on the bottom of the high performance insulation board a thin-layer plaster, preferably reinforced tissue, applied. Alternatively, at the bottom of the high performance insulation board arranged a drywall.

at Use of a blowing insulation material for Fill out between high-performance insulation board and uneven underside of the storey ceiling spanned cavity will be easy to use, especially in the case of a very uneven surface or with many installations provided blanket bottom. Preferably, the insufflation consists of Blähtonperlen, Frothed beads Glass, cellulose flakes or EPS flakes.

alternative When installing the high-performance insulation panels, a matt insulating material is used from rock wool, mineral wool, hemp or flax fibers or cellulose placed in the cavity and any unevenness and / or installations adapted by cutouts etc.

following An embodiment is based on the accompanying figures described in detail.

In this shows:

1 a Kellerkappendecke with installation pipes before a Dämmmaßnahme in cross section and

2 in the 1 illustrated Kellerkappendecke with a heat protection arrangement according to the invention in cross section.

In 1 is a basement ceiling 1 as shown in older buildings, in particular from the period 1900 to 1960, shown in cross section. The cap ceiling 1 has a load-bearing construction of double-T steel girders 11 on that in 1 perpendicular to the drawing plane. The steel beams 11 are supported on not shown basement walls. Between the steel girders 11 is a cap wall 12 made of solid bricks in slightly arched form. On top of this supporting structure are bearing woods 13 on the steel girders, for example 11 hung up. On the camp woods 13 is the wooden floorboard 14 applied. A above the cap wall 12 and under the wooden floorboard 14 forming cavity is filled with a filling 15 provided, for example, from slag, ash or sand or in an already carried out renovation from above with insulation.

Furthermore, on the bottom 10 the building ceiling 1 installations 16 placed. The installations 16 are, for example, electrical lines, water pipes, central heating pipes or the like.

Should now this existing Kellerkappendecke 1 on their bottom 10 , So be insulated from the basement side, difficulties arise for fixing rigid in itself insulation boards, as the bottom 10 the cellar ceiling 1 through the cap wall 12 is uneven and through the installations 16 has additional obstacles.

According to the invention, a heat protection arrangement 2 on the bottom 10 the cellar ceiling 1 according to 2 executed. The heat protection arrangement 2 consists of a closed, horizontally arranged layer of a self-contained high performance insulation board 21 attached to a substructure 22 consisting of transverse to the steel girders 11 the cellar ceiling 1 arranged wooden slats, by means not shown leveling screws in the cap wall 12 anchored aligned horizontally.

In which is between the uneven bottom 10 the cellar ceiling 1 and the high performance insulation board 21 or the substructure 22 forming cavity is to supplement the insulation a blow-in insulation 23 or a matt insulating material 24 brought in. The existing installations 16 be from the blow-in insulation 23 automatically enclosed without joints during the insertion process. When using the mat insulation 24 are at larger cross sections of the installations 16 corresponding cutouts from the matting insulation 24 cut out. Overall, this results in a substantially joint-free insulation of the bottom 10 the coffered ceiling 1 ,

If it is desired for aesthetic reasons, can on the bottom of the high-performance insulation board 21 a thin-layer plaster 20 , if necessary reinforced tissue, applied. The surface It then looks like a normal plastered ceiling.

In the production of the heat protection arrangement according to the invention, first of all the substructure 22 so under the existing cap ceiling 1 attached and aligned horizontally by means of the leveling screws, so that the substructure 22 at the deepest points of the uneven or with installations 16 provided building ceiling 1 is applied.

If then as a cavity insulation a mat insulation 24 is provided, this is in the forming cavity between the substructure 22 and cap walling 12 stuffed into. Possibly. are for installations 16 Cutouts in the mat insulation 24 provided. Then the high-performance insulation panels 21 on the substructure 22 attached without joints.

Will a blow-in insulation 23 for the cavity between cap bricking 12 and high performance insulation board 21 First, the high performance insulation panels are used 21 joint-free on the substructure 22 attached and then the blow-in insulation 23 injected through corresponding openings provided in the formed cavity.

With this heat protection arrangement can be building ceilings with a uneven bottom and / or with a variety of installations with an effective thermal insulation lower construction strength be provided. By combining a rigid thermal insulation material high heat conduction group with a soft or injectable insulating material medium heat conduction group while the workload is minimized because the bumps and installations through the soft or injectable insulating material wrapped whereas the inherently stiff high performance insulation panel the optical and constructive conclusion to the space below the ceiling form.
