Definitions
- the invention relates to an arrangement for insulating and sealing Building facades showing joints in the preamble of the claim 1 specified Art.
- she comprises a multilayer structure with a rubber-elastic web, which is glued to the surface with a composite adhesive.
- the surface structure consists of a filler layer, Fabric layer and plaster layer and is on the surface of the rubber elastic Path applied.
- This arrangement bridges the joints and copes with joint displacements up to 15 mm. This is directly due to the Elastic foil fully adhered to the surface.
- the arrangement protects against moisture and heat, but is no thermal insulation itself, although it does provide an additional one Contributes to thermal insulation.
- a disadvantage of the elastic The arrangement is that which is built up by a movement of the joint Restoring force or tension. This tension leads to Duration to detach the rubber elastic web or to accelerate Aging of the live material, see above that this is only a temporary solution.
- FR-A-2 394 651 there is an arrangement for bridging Joints or cracks described.
- This arrangement is a complex band, d. H. a strip of cloth with a plastic tape stuck under it is. The plastic tape can cover a tear. The strip of fabric is used in the top layer, the plaster, to the plaster on To hold plastic tape.
- This complex tape is applied to the joint area and stabilized by a flexible covering.
- This tape thus serves only the bridging of joints or cracks, with one renewed joint displacement again cracks in the crack or Joint cover can arise.
- Building facades affects the area of the building joints, which experience has shown not only badly affected by the weather but also the constantly occurring deformations the facade panels can no longer follow without damage. Cracks in the joint seals, detachments, water ingress into the construction and in the insulation layer are the consequences.
- This conventional structure includes an external, waterproof top layer made of, for example, external plaster, which is optionally reinforced with a suitable fabric and an insulation layer, which preferably consists of an insulation board and with the underlying plate material of the facade connected, for example glued.
- an insulation cover layer structure is on the same Jointed together like the one below Building facade, with a elastomeric material is used.
- the joints are transferred to the insulation top layer structure complex and requires special care during execution.
- This conventional insulation top layer structure for the renovation of Building facades shows the disadvantage that the original, outdated aesthetic impression of a plate-like composite building facade even after renovation preserved.
- a technically serious one The disadvantage is that the joints in the insulation top layer structure at least in the long run tightness problems cause, as the sealants even after such renovation of the sun and the atmosphere are exposed to and Embrittlement, tearing and leakage tend.
- the conventional insulation top layer structure is not permanent moisture-proof and will therefore need one within the foreseeable future Rectification.
- the object of the present invention is a Arrangement for insulating joints of building facades to create the kind mentioned above, in addition to a good Thermal insulation also provides a reliable sealing function in the long term guaranteed and an acceptable aesthetic impression mediated.
- Insulation top layer structure consists in the positive aesthetic Effect of the building facade thus renovated.
- Such safe sealing function is for thermal insulation and in addition, especially for special substrates with insufficient moisture resistance absolutely necessary, such as Concrete endangered by alkali silicate and ettringite reaction are. Due to the flexible decoupling area of the insulation layer deformations occurring in the area of structural joints without Damage absorbed by the insulation top layer structure. In particular, the risk of damage is basically relative thinly formed top layer of the structure, which also the sealing function comes to.
- the insulation top layer structure according to the invention causes deformation peaks kept from the outer skin and the top layer or distributed to a non-dangerous level.
- the Outer skin of the structure itself is formed so elastically, that they can withstand even partially increased deformations is able to develop without crack formation.
- the thrust-soft area advantageously extends on both sides each building joint over a predetermined area. Outside the insulation layer of the structure in this area conventionally be firmly connected to the ground.
- the shear-soft composite area is advantageously implemented as a soft adhesive layer.
- a permanently plastic adhesive layer can be provided or a shear-soft composite mortar, through which the insulation layer is connected to the substrate, that is to say the building facade.
- an elastomer layer can also be considered as a shear-soft composite area.
- the shear-soft composite area may be fiber-reinforced.
- the insulation layer has a multilayer structure and that the individual layers in the area of the structural joints have flexible connection zones, the material mentioned above, for example a permanently plastic adhesive layer, being considered as flexible material.
- the measures for uniform distribution of the substrate deformations can also consist in providing decoupling areas within the insulation layer, which are designed as bondless zones or as shear-soft zones in the area of the structural joints.
- the measures for non-destructive absorption of the substrate deformation by the insulation top layer structure according to the invention also in the outer skin thereof, that is, be provided in the cover layer itself.
- Prefers is the use of a particularly stretchable cover layer section in the area of structural joints. This comes into consideration for example an elastomeric material, which if necessary is fiber or mat reinforced.
- underground 5 a range of the width l o measures are taken in the illustrated in FIGS. 1 to 4 insulating cover layer structure in each case, by means of which the deformations of the subsoil are recorded in such a manner 5 that this structure, in particular the outer skin 2 is not damaged.
- Fig. 1 it is provided for this purpose, l relapsing soft to bond the insulating layer 3 on both sides of Hauwerksfuge 4 with a width of 0/2 with the substrate. 5
- a soft adhesive layer comes to the width l o or a corresponding layer of a shear-flexible composite mortar, a permanently flexible adhesive layer or a suitable elastomeric layer.
- FIG. 2 shows a two-layer insulation layer in the form of two adjacent insulation layer plates 3a and 3b instead of the single insulation layer plate 3 from FIG. 1.
- This two-layer insulation layer has two decoupling areas 6a and 6b, the decoupling area 6a being provided relative to the concrete base 5, similar to that in FIG. 1, while the second decoupling area 6b additionally decouples the two insulating layer plates 3a and 3b.
- Both decoupling areas 6a and 6b in turn extend on both sides of the structural joint 4 with a total width l o .
- the decoupling areas 6a and 6b like the decoupling area 6 in FIG. 1, can be designed as a flexible zone.
- the composite layers 6a and 6b can optionally be fiber or mat-reinforced. Such reinforcement can also be provided for the composite layer 6 of FIG. 1.
- the Entkoppelungs Club 6a can also be provided as a composite free Entkoppelungs Trial, wherein the composite free area 6a in practice advantageously by the Morrisbe mode of the substrate 3a with adhesive in a range of the total width l o on both sides of the Bauwerksfuge is provided.
- the outer skin or the outer layer is the insulating cover layer structure formed 8 1 elastically, at least in a portion of the total width l o opposite to the Bauwerksfuge 4.
- This area 8 is specially adapted stretchable and preferably mat or fiber-reinforced.
- An elastomer, for example, can be considered as the material for the particularly stretchable region 8.
- Fig. 3 is the insulating layer or under the outer skin 8 Insulation board 3 firmly glued to the concrete base 5, namely also in the critical area of structural joints.
- the insulation board can be used in this critical area Concrete base 5 coupled softly to the base 5 be.
- Fig. 4 instead of the single insulation board 3 a multi-layer insulation board structure can also be used is designed, for example, according to FIG. 2.
