DESCRIPTION:
BRIEF SUMMARY
The invention relates to a method for attaching mechanical devices for guiding, hanging, holding or supporting objects on an insulation layer lining masonry and of low mechanical strength, in particular running rails for slatted roller blinds or slatted shutters in window and door openings insulated on the outside and a machine to carry out the method with an insulation layer made of a foamed plastic.
In many cases, buildings which were erected up to the beginning of the 1970's no longer meet present heat insulation regulations and/or the change in attitude towards environmental protection and conservation of energy resources despite otherwise being of good building material. Reconstruction takes place primarily by applying an outside insulation which provides a better heat balance than a subsequently fitted inside insulation which is, in principle, likewise possible.
Subsequently fitted insulation layers applied to new buildings almost always consist of heat insulating blocks with standardized dimensions which can be cut, if required, on the site using simple devices. After assembly, exposed blocks are usually covered with plaster.
It is known to produce heat insulating blocks of rigid, foamed plastic, for example on the basis of polyurethane or phenolic resol resins. These predominantly closed-cell foams have a high insulation capacity, but they are sensitive to pressure due to their low mechanical strength. No objects can be attached to the insulation layer using customary devices, such as for example plugs.
On a customary outside or inside insulation layer, it is therefore not possible to mount running rails for slatted roller blinds or slatted shutters, suspension brackets and resetting means for slatted blinds or window shutters, consoles to provide a shelving surface, light fittings or hooks for heavy pictures etc.
According to the known prior art, mechanical devices for guiding, handing, holding or supporting objects are therefore attached, according to a first variant, in the masonry located behind the insulation layer. This requites, on the one hand, increased and more complicated work and, on the other hand, longer mechanical devices with a larger cross-section, for example screws. This, in turn, requires larger holes to be drilled and larger plugs to be inserted.
According to a second variant, at the place expected for the attachment of mechanical devices for guiding, hanging, holding or supporting objects, insulation blocks are used which are fitted on the outside with a panel of increased mechanical strength. This requires special blocks to be used according to an exact plan because their position can subsequently no longer be altered. In particular in the region of window and door openings, precise and careful cutting work must be carried out. Furthermore, this variant requires workers of higher qualifications to be employed which thus further increases the costs.
SUMMARY OF THE INVENTION
The inventor has set himself the object of providing a method of the type discussed above which allows a simple and cost-saving manner of work which is also suitable for unskilled workers and does not have to be planned in detail in advance. Furthermore, a machine to carry out the method for an insulation layer made of foamed plastic is to be used.
In relation to the method, the object is achieved according to the invention is that masonry, at least one-third of the insulation layer remaining between the recess and the masonry, bonded in over the whole surface on the base of the recess, at least the outer most panel being of high mechanical strength, and strength.
According to the invention, the insulation layer, in particular an outside insulation, can also be applied in the region of window and door openings without special precautions needing to be taken for the attachment of objects, in particular running rails for slatted roller blinds or slatted shutters, suspension brackets for slatted blinds or window shutters, etc. The recesses can be made with little effort in situ in the finished insulation la
