Definitions
- the present invention relates to a method for installing a roofing plate and a roofing plate for laying according to the method. It has applications in the building industry, in the construction or renovation of pitched roofs of the type using battens on rafters.
- the roofs concerned by the invention conventionally comprise from the inside towards the outside of the building a frame made up of rafters which are arranged regularly and parallel to each other in the direction of the maximum slope, under-roofing plates placed on said rafters. , battens perpendicular to the rafters and fixed on the said rafters and serving as a hooking line for roofing elements of the tenon-tile type, slate, etc.
- rafters which are arranged regularly and parallel to each other in the direction of the maximum slope, under-roofing plates placed on said rafters.
- Such a structure is described in document DE-1784371 which implements corrugated sheets resulting from a mixture of fibers and bitumen.
- the roofing sheets are intended to provide relative insulation between the exterior and the interior of the building.
- the plates are arranged so that the corrugations are parallel to the rafters, that is to say in the direction of the maximum slope.
- the roofs being generally of surface much larger than that of a plate, the latter are arranged partially overlapping between them so that the water having been able to be collected and / or flowing from a plate located in a higher zone of the roof passes over the plate arranged continuously in the lower zone without flowing inside the building.
- the invention proposes to use corrugated roofing sheets. These sheets made of bitumen-impregnated fibrocellulose are rectangular and the corrugations are parallel to the two edges of the length. This type of plate does not however, does not have the same rigidity along axes parallel or perpendicular to the corrugations. Thus, in the traditional pose where the corrugations are parallel to the rafters, the plate tends to bend and has an arrow in the axis perpendicular to the corrugations, that is to say between the rafters.
- the spacing between the rafters is not standardized and the installation of this type of plate can therefore lead to a work of installation of battens to support the plates or significant suspension and relatively large losses of material if the width of the plate does not correspond to a multiple of the spacing of the rafters. It is therefore desirable to implement an installation process and under-roofing plates which limit these constraints.
- the invention therefore proposes to use the particularity of greater rigidity of the plate in the axis of the corrugations for facilitate installation and limit material losses, the rigidity changing according to the angle between the corrugations and the rafters.
- the invention relates to a method of installing at least one sub-roofing plate in a roof with a slope line of a building, the roof comprising from the inside to the outside of said building:
- a sub-roofing plate which is made of fibrocellulose impregnated with bitumen with four corners and four edges and comprising corrugations intended to collect water which may have passed through the cover and in that the said plate is oriented so that the corrugations are inclined obliquely with respect to the rafters at an acute angle ⁇ open towards the bottom of the roof, the angle ⁇ greater than 0 ° being such that the water collected flows naturally by gravity towards the bottom of the roof.
- the plate is oriented so that the corrugations are inclined at an angle ⁇ greater than 0 ° and less than 67.5 ° relative to the rafters,
- the plate is oriented so that the corrugations are inclined at an angle ⁇ of approximately 45 ° relative to the rafters, - in the case of the use of several plates, the plates partially overlap at their junctions, the plate arranged towards the top of the slope coming in partial overlap on the plate arranged towards the bottom of the slope so that the water coming from the plate arranged upwards flows on the plate arranged downwards without flowing into the building , - in the case of implementation of a plate in two parts, the plate being split along a diagonal, the parts partially overlap at their junction along the diagonal, the part disposed towards the top of the slope coming on the part arranged at the bottom of the slope so that the water coming from the plate arranged at the top flows on the plate arranged at the bottom without flowing in the building,

- the invention also relates to a sub-roofing plate for a roof with a slope line of a building, said roof comprising from the inside to the outside of said building:
- the roofing plate is made of bituminous impregnated fibrocellulose, rectangular with four corners and two edges of length and two edges of width, and it has corrugations intended to collect water which may have passed through the roofing. and the undulations make an angle ⁇ greater than 0 ° with respect to one of the edges of the length, the angle ⁇ being such that the collected water flows naturally by gravity down the roof following installation during from which said plate is oriented so that at least one of the two edges along the length rests parallel on a rafter so that said undulations are arranged obliquely inclined relative to the rafters at the angle ⁇ open towards the bottom of the roof.

- the corrugations being inclined relative to the rafters, a greater number of the latter is supported by the rafters and the greater rigidity in the axis of the corrugations makes it possible to reduce the constraints compared to the traditional pose where the corrugations are parallel to the rafters .
- the possibility of using plates divided into two parts along a diagonal also limits the losses of material when it is necessary to remove any corner or edge of plate not or insufficiently supported by a rafter.
- Figure 1 shows the installation of a first type of plate
- Figure 2 the installation of a second type of plate
- Figure 3 a third type of plate
- Figure 4 a fourth type of plate; Figure 5, the installation of a fifth type of plate, and Figure 6, the installation of a sixth type of plate.
- Figure 1 there is shown seen from the outside and above a building, a roof in the process of installation comprising a series of rafters 6 arranged parallel to each other and extending along a line of slope between a high point HT and a low point BS.
- a rectangular roofing sheet 1 with four corners 2, 2 ', 3, 3', two edges of length 2-3 and 2'-3 'and two edges of width 2-2' and 3-3 'is arranged flat on the rafters 6.
- the plate 1 is made of bituminous impregnated fibrocellulose and comprises corrugations 4 parallel to each other and to the two long edges.
- the plate having greater rigidity according to the corrugations and therefore the length, it is arranged obliquely with an angle ⁇ open at the bottom between the corrugations and the rafters.
- the plate is also placed so that at least one of the two corners 2 or 2 'of width 2-2' towards the top of the roof rests on a first rafter and that at least one from the two corners 3 or 3 'of width 3-3' towards the bottom of " the roof rests on a second rafter.
- the two corners resting on rafters are 2 for the top and 3 for the bottom. Equivalently it is envisaged that the two corners resting on the rafters are (2 and 3 ') or (2' and 3) or (2 'and 3').
- the spacing between the rafters is' ready, it is envisaged that three or four of the corners can rest on rafters.
- the angle ⁇ between the corrugations and the rafters is less than 90 ° and greater than 0 ° in order to allow a flow of the water having been able to cross the cover maintained by battens, these last two elements not being shown in Figure 1.
- the sub-roofing plate 7 used is in the form of a parallelogram with four corners 2, 2 ', 3, 3', four sides or edges with two edges 2-3 and 2'-3 'according to the length and two edges 2-2 'and 3-3' depending on the width.
- the corrugations 4 of the plate are parallel to the two edges 2-3 and 2'-3 'of length.
- the plate 7 is here arranged on the rafters 6 so that the two edges 2-2 'and 3-3' in width are perpendicular to the rafters. In such an installation configuration there is at least one of the four corners which rests on a rafter. Depending on the spacing between the rafters, two or more corners may rest on rafters.
- At least one of the corners, 2 ′ in FIG. 2 is placed on a rafter.
- another corner will be placed on a chevron, for example 2 or 3 or 3 'and in other modes, two or more of said corners will be arranged on rafters.
- the preferred mode of installation is that where at least one corner rests on a chevron, it is however also envisaged that none of the corners rests on a chevron, but that they are each distributed in a manner to be substantially adjacent to a rafter so that the spans without support are equivalent.
- the two types of roofing plate of Figures 1 and 2 are of the type with corrugations parallel to the two edges of the length.
- Other general shapes of this type are envisaged, for example trapezoidal. If these types of plates allow the implementation of the invention, they nevertheless have certain drawbacks and in particular for the type of Figure 1 to cause material losses on the ridge of the roof because the edge of the width of plate 1 is not parallel to the ridge. For Type 2, handling and storage can be more complicated due to the general shape of the plate 7.
- the installation consists in placing at least one of the edges of the length parallel on a rafter so that the undulations make an angle ⁇ with the rafters.
- Figures 3 and 4 show two examples of such plates which are parallelograms with four edges.
- the corrugations 4 of the plate 8 are parallel to the two edges along the width 2-2 'and 3-3'.
- the corrugations 4 of the plate 9 are perpendicular to the two edges along the width 2-2 'and 3-3'.
- a first part 10a with three corners 2a, 2 ', 3'a and a second part 10b with three corners 2b, 3, 3'b are defined.
- the two parts 10a, 10b of the plate can be translated along the diagonal with respect to each other, each of the two edges of the length can be arranged substantially on a rafter.
- the edge of the length 2b-3 is on a first of the rafters 6 and the edge of the length 2'-3'a is on a second of the rafters 6.
- the two parts 10a and 10b of the sub-roofing plate overlap in the area of the diagonal 1 1 perpendicular to the corrugations 4, the part disposed upwards coming in partial overlap of the part arranged towards the bottom of the roof.
- the undulations of the two parts are arranged in the extension of one another as for the wave 4a of the part 10a which continues with the wave 4b of the part 10b.
- the corrugations 4, 4a, 4b of the plate 12 are oblique at an angle ⁇ relative to one of the edges of the length.
- the roofing plate 12 is in two triangular parts 12a and 12b, the plate 12 being split along one of its diagonals, said diagonal being parallel to the corrugations.
- a first part 12a with three corners 2a, 2 ', 3'a and a second part 12b with three corners 2b, 3, 3'b are defined.
- the two parts 12a, 12b of the plate can be translated along the diagonal relative to one another, one can have each of the two edges of the length on a rafter.
- the edge of the length 2b-3 is on a first of the rafters 6 and the edge of the length 2'-3'a is on a second of the rafters 6.
- the two parts 12a and 12b of the roofing plate overlap in the area of the diagonal 13 parallel to the corrugations 4, the part arranged upwards partially overlapping the part arranged downwards of the roof.
- the undulations of the two parts are arranged in the extension of one another as for the wave 4a of the part 12a which covers and continues with the wave 4b of the part 12b.
- under-roofing plates of the mirror image type of those of FIGS. 5 and 6 are also envisaged.
- the roofing plates can be precut in the factory and delivered in two parts, the plates can have a weak area along the diagonal facilitating the separation into two parts of the plate during the poses if necessary or the installer can cut a plate according to the diagonal which will be identified or not. It is also envisaged that bitumen is specially distributed in the area of the diagonal so that when two plates are partially overlapped, adhesion can take place.
- the spacing between the parallel rafters 6 is shown in Figures 1, 2, 5 and 6 as being substantially regular.
- the invention is also applicable in the case where the spacing between the rafters is not regular.
- the angle ⁇ is chosen according to the dimensions of the under-roofing plate so that the installation of several partially overlapping plates be optimized. For example for two adjacent plates, the undulations of their corresponding edges of the length open at heights such that partial overlap is possible while the edges of the width of the two plates are at the same height on the roof. It is envisaged that this optimization also concerns the edges of the width.
