Description

The invention relates to a gradient insulating plate made of heat-insulating foam.

Gradient insulation plates of this type are known per se. They consist either of wedge-shaped plates with a flat surface in cross-section, are designed as ridge plates with diagonally aligned to the base ridge line with additional slope on both ridge sides or as Kehlplatten with diagonally aligned to the base Kehllinie with additional slope to the throat line down.

They serve to discharge surface water (rainwater) in the direction of drainage points (gutters, gullies), especially on roof surfaces. If this is not just about being able to lower an area with a low weight (in contrast to the weight-heavy sloping screed), but also about thermal aspects, then the provisions of the Energy Saving Ordinance (EneV) must be observed. This provides that Gefälledämmung is carried out in two layers on the roof surface. These two layers (ground and applied slope gradient insulation) should be arranged offset to one another and glued together so that no thermal bridges occur in the joint area of the plates by subsequent shrinking or deformation, seen over the thickness of the two layers.

The insulation for a roof, which was already designed in the downhill slope, must be carried out with uniformly thick flat roof EPS panels with integrated shiplap. This shiplap is a constructive way to avoid continuous thermal bridges in the insulation layer.

The invention had the object of providing a single-layer insulation layer for gradient insulation plates, which prevents continuous thermal bridges. By the invention, in particular, the material for an existing gradient insulation for a single-layer processing can be changed.

This object is achieved by the characterizing features of the structure of a plate element and a locking element. Advantageous developments emerge from the features of the subclaims.

The basic idea of the invention lies in the circumferential groove in the lower region of the plate elements. The adjoining next slope plate has a groove at the same height to the base and shape. This groove is filled with a tight fitting EPS insulation-and-slats element and connects adjacent panels together. This locking element is advantageously made regardless of the material used for the insulation of gray EPS material. If the gradient insulating plates shrink or deform for thermal reasons, this locking element prevents the formation of thermal bridges.

The fixing of adjoining plate element in height by the connecting bar element additionally ensures that when gluing the base with the roof surface, the plate elements do not set differently. The adjoining surfaces of the gradient insulating plates thus remain at the same height.

In the processing of the gradient insulation panels result from the inventive design significant savings in installation time and installation costs, since the entire roof surface must be designed only once with insulation and only one surface to be treated with adhesive.

The avoidance of thermal bridges is particularly supported when two bar elements are provided with each half groove height. The locking elements can then be superimposed on intersection points and offset in length offset from one another into the groove.

Due to manufacturing tolerances, matched tolerances must be maintained both with regard to the groove arrangement, the groove cross-section and the bolt elements, which are within ± 10% of the specified dimensions.

For the preparation according to the invention of conventional gradient insulation panels, it is important that the side surfaces remain essentially unchanged, since the insertion surfaces themselves do not change due to the insertion of a groove. According to the invention equipped panel elements can be further used by omitting the locking elements for a two-ply insulation layer. When inserting the locking elements, a limited adhesion of the second layer may be sufficient. An already existing installation plan can be taken over unchanged, since the insertion of the groove does not change the cover size of existing incline plates.

In the drawing, an embodiment of the gradient insulating plate according to the invention is shown schematically and will be described below.

The figure shows in cross-section one of a first plate element 1 and a latch element 2 existing gradient insulation plate. The plate element 1 consists of heat-insulating EPS material. The latch element 2 It is advantageously made of gray EPS material to give a conspicuous visual connection and to cover all possible EPS grades.

In the plate element 1 is one parallel to the base 9 circumferential groove 3 inserted with a groove depth 4 of about 20 mm and a groove height 5 of about 20 mm.

The latch element 2 is adapted in cross-section to the groove cross-section so that it presses into the groove 3 can be pressed. The cross-sectional width of the latch element 2 is obviously larger than the groove depth 4 , preferably twice as large, ie about 40 mm.

One at the lower slope point of the plate element 1 attached adjacent plate element 7 has a same groove 3 on like the first plate element 1 , About one in the two grooves 3 inserted latch element 2 Both are plate elements 1 . 7 connected at the same height.

The lower limits of the grooves 3 have an equal distance 8th from about 20 mm to the base 9 the plate elements 1 . 7 ,

The latch element 2 may preferably consist of two equal parts 2 ' . 2 ' each consist of half cross-sectional height. The two latch elements 2 ' 2 ' can then be superimposed, but offset in length to each other in the groove 3 be pressed so that there is no risk of a continuous thermal bridge at any point.
