Description

92744

Roof plate. - Takplatta.

The present invention relates to a roof panel according to the preamble of claim 1.

Modular roof elements made of sheet metal are well known. U.S. Pat. No. 2,830,546 discloses a modular roof tile having a rectangular shape with one side bent upwards into a V-shape and provided with an extension at one outer end, the opposite edge being bent downwards to a similar V-shape and the upper transverse to the transverse shape .

It is an object of the present invention to provide a metal roofing sheet which is extremely simple to install.

It is a further object of the invention to provide a modular element which provides high stability to a built roof.

It is a further object of the invention to provide a modular element which, in practice, provides complete tightness against water, wind and, in general, atmospheric substances.

A further aspect of the invention is to provide a modular element which results in a pleasant appearance.

It is a further object of the invention to provide a modular element which allows the roof to adapt to the thermal expansion of individual elements.

It is a further object of the invention to provide an element which allows efficient natural roof ventilation to be achieved.

2,92744 These and other objects, which will become apparent from the following description, are achieved according to the invention by a roof panel according to the preamble of claim 1, characterized by the features set forth in the characterizing part of claim 1.

The present invention will now be further elucidated with reference to the accompanying drawings, in which:

As can be seen from the figures, a modular element according to the invention, generally indicated 1, comprises a plate part made of electrolytically treated normal or stainless steel, copper, painted or unpainted aluminum or another metal, pre-painted or pre-painted.

The element 1 is entirely rectangular in shape, of which: the edge 2 of the right hand (referring to Fig. 2) is bent forward into a U-shape, i. towards the outer surface of the element 1, and has a hole 3 passing through it at the top thereof. Prior to bending the edge 2 of the right hand forward, bending it in two opposite directions so that the two flanges of said edge 2 are symmetrically about the general plane of the element 1; . - the edge 5 of the left hand is bent backwards into a U-shape and is provided with a hole 6 corresponding to the hole 3 in the side edge of the right hand; the upper transverse edge 7 is bent forward into a U-shape; although it is not absolutely necessary to arrange continuous bending along the upper edge 7, it is advantageous because, as will be seen below, it guarantees good tightness against water and wind force, and in addition gives greater freedom in the relative positioning of the various elements. However, the bending of the edge 7 does not include the side edge 2 of the right hand or the outer flange of the side edge 5 of the left hand; The ends of the lower edge 8 are slightly rounded and slightly bent backwards. As will be seen below, this gentle bending is arranged for both aesthetic and functional reasons in that it assists in the compaction of water and wind.

The element according to the invention is formed of a sheet metal strip from which a part corresponding to the developed element has been pierced without parts which are not present in the final element, i. the lower part of the outer flange of the left hand edge 2 and the end of the lower edge 8.

The perforated body is then subjected to conventional bending operations to form element 1. This can then be surface treated as long as the original sheet metal strip has not been subjected to such treatment.

For installation purposes, a support grid, preferably of wood or possibly metal, is required, the grid comprising a plurality of longitudinal members 9 arranged parallel to each other at a distance from each other which substantially corresponds to the distance between the lines 7 in the element 1 below which edge 8 is bent.

The lower left-hand roof element is then placed in this truss and fastened to the corresponding longitudinal member 9 by screws screwed through holes 3 and 6, which holes are arranged at the two lateral edges 2 and 5. 5 engages the forward-bent edge 2 of this pre-assembled element on the right hand, and is then fastened to the same longitudinal member 9 with additional screws through the holes 3 and 6. When the horizontal element row is completed, the row above is started. The first element is placed in an overlapping arrangement between two adjacent elements 1 placed at the end of the left hand of the lower row, so that the hook extension 4 of the right hand edge 2 of the new element grips the folded elements until the second row is completed, after which the third row is installed and so on until this roof corner is completed.

If there are two corners in the roof, the two upper rows of elements 1 are joined together by brush elements 10 and 11, which adhere to the two bent upper edges 7 of the elements of these two rows, whereby the brush elements 10,11 are then joined together either directly (see Figure 6) or U-section 12 (see Figure 7).

From the above, it is clear that the modular elements according to the invention are very advantageous in that: they are very easy to install, they allow the construction of roofs with high mechanical stability, they offer excellent tightness against water and wind, they result in a pleasant appearance; By keeping the roof virtually insensitive to thermal expansion by fully absorbing it, “they allow you to build roofs with excellent natural ventilation.
