DE2839767A1 - Sheathed sloping roof heat insulated substructure - comprises overlapping coated insulating strips with support beams and square timbers - Google Patents

Abstract

Standard building materials are used, in construction of a heat-insulated substructure for fully sheathed, double-skinned sloping roofs to be covered with roof panels. Lengths of insulating material (3) with an overlapping coating (4) are loosely laid on the effectively damp-proofed (2) roof surface (1), for rolling up from eaves to ridge, held by support beams (5) at an intervals. The coating layers protrude far enough on two sides to cover these beams and the previously laid parallel length. Square timbers (6) are fastened on the support beams, in the downward direction, to provide air passage space, as bearers for the roof batten system. This is effectively heat-insulating, and can be adapted to local needs on old, as well as new buildings.

Description

Experience for the production of a thermally insulated under-

Construction with formed pitched roofs The present invention relates to the production of a thermally insulated substructure for fully shuttered double-shell pitched roofs using commercially available building materials.

It is known in so-called cold roofs, the space under the roofing panels to be insulated with thermal insulation layers. For example, there are heat-insulating components, Consists of a trough made of dimensionally stable with angled edge strips Foil for laying on the roof battens and thermal insulation panels embedded in the hollow, for use (see DE-PS 19 04 484). About these thermally insulating hollows are then the roofing elements (bricks, slates, shingles, etc.) laid. A similar known design of a sub-roof consists of one on the roof battens in the direction of fall laid plastic film, which through the hanging lugs of the roofing panels in their position is held, with the film between the roof battens with thermal insulation Elements is occupied (DE-PS 17 59 073).

Both systems have the following disadvantages: Continuous ventilation from eaves to ridge between the insulation layer and roofing elements is not given. This means that moisture no longer diffusing out of the interior of the room is no longer possible is properly discharged to the outside, so that condensation forms under the plates can take place.

Furthermore, ready-to-install roof elements for sub-roofs are known, characterized by I-, T- or Z-shaped ones running in the longitudinal direction of the roof element Beams connected at the bottom via flat pressed plates and at the top Are covered over a roof membrane, the above-described interior with a Foam filling made of rigid foam is provided. These roof elements are on the rafters attached in the direction of fall of the pitched roof (cf. Gbm 7 308 371).

With this type of roofing, the roof structure must be constructive in the preliminary planning be matched to these elements. Subsequent assembly on conventional Roof trusses appear economically expensive.

Finally, they are relocatable, made of PU foam and with aluminum sheathing provided plate elements known that parallel to the eaves and ridge directly on the Rafters are attached. The individual plate elements are on their long side provided with a fold, which also represents battens for the cover plates. Here, too, there is continuous ventilation of the space between the insulation elements and covering panels from eaves to ridge are not given.

There was therefore the task of fully switching for the full thermal protection Pitched roofs using commercially available roofing materials one To develop a substructure that does not have the disadvantages described and both for new buildings and for roofing according to the local conditions is individually applicable.

The solution to the problem is a method for Production of a thermally insulated substructure for fully shuttered double-shell, Pitched roofs to be covered with roof tiles using commercially available Building materials, which is characterized in that on the boarded with wooden materials and with an effective vapor barrier (2) provided roof surface (1) from the eaves Thermal insulation sheets (3) that can be rolled to the ridge and parallel to the eaves with overlapping Liner layer (4) loosely laid on and at intervals by supporting planks (5) in their Are held in position, the liner layers of the insulating strips on a longitudinal and one head side protrude so far that both the support planks and the abutting edges each previously laid parallel insulation membrane are covered, and that on the Support planks in the direction of fall of squared timber (6) to create the ventilation space be attached from eaves to ridge as a carrier for the roof battens.

The insulation sheets> can be on the side that the roofing sheet is facing, have ventilation ducts.

Description of the process: The Wooden formwork nailed to rafters (1). This is due to structural reasons Required vapor barrier (2) (e.g. 8th site roof membrane with glass fleece or aluminum tape insert) Nailed on concealed, seams and joints fully glued.

The intended as an insulating layer, with roofing membranes e.g. made of organic or inorganic foams laminated Insulation strips made of e.g. plastic rigid foam (3) (width 1, o m) are each impregnated between Support planks (5) (distance from each other 2, o m) loosely inserted parallel to the eaves.

The seam and joint overlaps (4) remain unglued in order to provide diffusion resistance to keep the lamination layer low. Square timbers are used as the carrier of the roof battens (6) 6 x 6 cm fixed parallel to the slope on the support planks with a distance of 1.0 m.

This simultaneously creates the necessary ventilation gap between Thermal insulation and hard roofing to dissipate out-diffusing water vapor created and condensation and ice formation in the gap avoided.

The advantage of the system is that there are only a few commercially available Materials a fully-fledged building physically and thermally technically, but inexpensive Sub-roof construction can be created by the existing overlaps is immediately rainproof on the runway.

In Figures 1 and 2 is a according to the method according to the invention Manufactured thermally insulated construction shown for a pitched roof.

Fig. 1 shows the pitched roof in section parallel to the eaves, Fig. 2 a cut in the direction of the slope.
