Abstract

A drainage layer (V)(3) runs vertical in a plane behind the block (1) plaster layer (2) and is composed of a number of V channels partly enclosed in plastics foam (4). The cross wall consists of drainage layer (5) and an outer horizontal connecting channel. The drainage channels (4) connect in part with the horizontal drainage layer (8) and are made of a structural matrix (7). Condensate arising is led off via the horizontal drainage channels (9) of layer (8) and the inside face of lightweight block (10) to regulate the drying of the block as such. Vertical channels (4) are linked materially and spatially by an outer horizontal channel (6) made up from the block itself.

Description

The invention relates to a lightweight building block for a thermal insulation composite system according to Preamble of claim 1.

Such lightweight building blocks made of a rigid plastic foam are available in different designs types and uses known. These lightweight components are used especially in construction in the fields of lightweight construction, thermal insulation and Sound insulation. In an advantageous manner, they are here, among other things, at Thermal insulation of buildings to infill load-bearing structures, both in Half-timbered building, as well as in reinforced concrete skeleton construction, as well as in the overall system as insulation facade used. Furthermore, an application profile is known in which lightweight components poured with concrete after assembly and thus build a load-bearing scaffold and integrate.

The design of the lightweight building blocks is known in a variety of ways. In the The internal structure of the lightweight building blocks is usually assumed to be homogeneous from, whereby the material-typical porosity can be of different sizes. The outside surfaces were in a different structure, based on the respective application cases, designed. For example, the lightweight building blocks for the adhesive application of Clean up special surface roughening. The use of lightweight building blocks is thus always from the special requirements of the client, the size of the lightweight building blocks and determined their specific density.

In DE-PS 8 01 853 a multi-chamber hollow block made of concrete or the like described, the enclosed cavities, formed by specially gestal tete multi-branch, for example H or T-shaped, bridge pieces.

DE 44 33 161 A1 shows a rear-ventilated insulation board made of foam plastic with a uninterrupted cover plate on the building side, a cover plate facing away from the building and Spacers between the two cover plates that extend over the entire height of the insulation board Clear through air ducts.  

Another variant is disclosed in DE 44 09 763 C1. It shows us a lightweight building block a rigid plastic foam with essentially flat cavities on the inside Ren, especially for use in the association for thermal insulation infills of wear the constructions and for cladding of structures, the cavities inside of the lightweight building block are arranged in several levels and the rear ventilation of the Association takes place in the outermost level.

The disadvantages of the known technical solutions according to the prior art consist on the one hand in the low breaking strength of the lightweight building blocks due to the much wrinkle cavities in connection with the small wall thicknesses inside. As a result, the processing sequences are designed for the user relationship moderately difficult, because of the low breaking strength, a high degree of caution in the Processing of the lightweight building blocks according to the state of the art is necessary. It happens despite all caution when processing to breakages or damage to the lightweight components the desired and promised and guaranteed wall construction irreversibly disrupted. Another disadvantage is that the insulation value of the lightweight building blocks in relation to DE 44 33 161 A1 and DE 44 09 763 C1 deal with the layer thickness of the rear ventilation level reduced. This is accompanied by the risk of an insufficient calculation basis for the k value of these lightweight building blocks.

The invention is therefore based on the object of a lightweight module made of a plastic To further develop hard foam of the type described in the introduction in that low mass of the lightweight building block a maximum total wall thickness variability Consideration of a good thermal insulation property, a high compressive strength, a high one Breaking strength and good vapor permeability is achieved, with a targeted Removal of a condensate that occasionally occurs via a statically stable structure shall be.

This object is inventive in connection with the preamble of claim 1 solved by the characterizing features of claim 1. Further training of the Invention are set out in the subclaims.

The lightweight module according to the invention made of a rigid plastic foam, which in particular Association for thermal insulation of load-bearing structures and for bracing construction is used, at least one points in a level behind the Plaster base layer of the lightweight building block arranged drain layer V (vertical) that from several drain channels V (vertical) partially enclosed by rigid plastic foam, their transverse walls (drain layer V) and at least one outer horizontal composite channel exists. The drain channels V (vertical), which are in a spatial connection with the Drain channels H (horizontal) of the drain layer H (horizontal) are made of one Structural structure built up, that in connection with the drain channels H (horizontal) the drain layer H (horizontal) for the targeted removal of a condensate that occasionally occurs ensures and thus a controlled drying of the building body.

An advantageous embodiment of the subject matter of the invention provides that the drain channels V (vertically) over at least one outer horizontal composite channel, which consists of a structure structure is built up, are in a material and spatial connection.

According to the invention it is further proposed that the structural structure of the drain channels V (vertical) and the outer horizontal composite channels macropores and / or capillary pores and has at least the same static stability as that it encloses Hard plastic foam of the lightweight building block.

An expedient embodiment of the subject matter of the invention specifies that both the Arrangement as well as the outer shape of the drain channels V (vertical) in connection with the Transverse walls (drain layer V) and the outer horizontal composite channel an optimal Ensure static stability of the plaster base layer of the lightweight building block.

According to the invention it is particularly advantageous that a horizontal extension or Shortening of the drain layer H (horizontal) facing the building and thus the on the inside (lightweight building block) visibly designed drain channels H (horizontal) Regulation and / or staggering of the plate thickness of the lightweight building block takes place.  

Finally, it is proposed that the drain channels H (horizontal) consist of horizontal mecha African openings exist, both the static properties and the heat Do not reduce the insulating properties of the lightweight building block.

Further details of the invention are shown schematically in the drawing with reference to Darge presented embodiments described.
