Description

Title of the invention: Ready-to-use cover elements technical field

[0001] The invention relates to the technical field of roofing elements, and more particularly to roofing elements ready for use before use on a construction site.

[0002] The invention also relates to a method for cutting said ready-to-use cover element. State of the art

[0003] In the field of roof covering, said roofs usually comprise several slopes covered with roofing elements of varying dimensions.

[0004] The junction between the different slopes and hips of the roof, at the level of the framework, is called a hip when the junction is projecting or a valley when the junction is internal. The hip is therefore the junction between a slope and a hip, a hip and a hip, or the junction between one slope and another; the valley is therefore the junction between one slope and another.

[0005] At these connection points, it is necessary to cut the roofing elements. Indeed, depending on the dimensions of the roofing element, these are generally installed so that one of its edges, usually the lower lateral edge, is horizontal and parallel to the roof overhang.

[0006] Thus, the roofing elements near the valleys or ridges must necessarily be cut in order to be laid on the roof.

[0007] However, cutting the roofing elements at the edge of the slope or hip creates numerous problems. Indeed, the cutting work is carried out mainly on the roof, but also on the ground by the operator after having personally measured the cutting angles of the roofing elements.

[0008] These cutting conditions are very unfavorable in terms of ergonomics and safety since the operator performs the cutting on roofs with slopes ranging from 10° to 90° depending on the type of roof.

[0009] In addition, slopes can be slippery in adverse weather conditions and the handling of cutting devices by the operator is difficult because of their weight, which makes cutting roofing elements perilous.

[0010] Moreover, the time required to perform these cuts is time that the operator is not performing other operations, consequently slowing down the coverage of a roof.

[0011] Similarly, the operator may make a mistake in his measurements or miss his cut, causing a superfluous use of raw materials.

[0012] The invention therefore falls within this context and seeks to resolve all of the aforementioned drawbacks.

[0013] Thus, the invention seeks to make the use of roofing elements easier, adaptable to any type of roof and reducing risks for construction site operators.

[0014] Moreover, the invention is situated in a context of reducing raw material loss, particularly due to higher cutting precision. Presentation of the invention

[0015] The invention relates to a ready-to-use roofing element, easy to install on a roof slope, adaptable to any type of roof and whose use reduces risks for operators on site.

[0016] Another object of the invention is a method for cutting a cover element according to the invention.

[0017] For this purpose, a ready-to-use roofing element has been developed, intended to be placed at the edge of a roof, at the end of a row of roofing elements and to be positioned according to an orientation defined by a hip or valley and the overhang of an adjacent roof.

[0018] According to the invention, the cover element has a predetermined initial shape and has, in this initial shape, at least one cut and / or pre-cut forming an angle with an edge of said initial shape, said angle being determined by the position of the row and by said orientation.

[0019] The term "ready to use" refers to the fact that the roofing elements are pre-cut before being installed on a section of a roof. In other words, the measurements of the angles and positions are taken on the roof section or on the construction plan, prior to the installation of said roofing elements.

[0020] Thus, the operators on a construction site only carry out the operations of installing the roofing elements.

[0021] In the same sense, the roofing element includes an identification system enabling the position of the roofing element to be known on a roof slope, i.e. the predetermined row and the predetermined position of the roofing element.

[0022] The term "at the end of a row" refers to the last two cover elements at the ends of a row of cover elements. In other words, at each end, there may be two to three pre-cut cover elements ready for use.

[0023] In a particular embodiment, the end of the row is composed of a pre-cut cover element comprising at least two cover units connected together.

[0024] In a particular embodiment, the roofing element is a mechanical roofing tile.

[0025] Advantageously, a pre-cut, ready-to-use roofing element according to the invention saves time on the installation of roofing elements on a roof slope. Indeed, the fact that the operator no longer performs the operations of measuring and directly cutting the roofing element allows them to focus solely on the installation of the roofing elements.

[0026] A pre-cut cover element also allows for gains in the safety of personnel at the workstation, and the possibility of installation regardless of weather conditions, provided that there is access to the construction sites.

[0027] In addition, the fact that the roofing elements are cut before they are laid allows the operator to avoid taking risks when cutting them, while reducing the loss of raw materials thanks to a more precise cutting of said roofing elements.

[0028] In order to obtain ready-to-use roofing elements, it is necessary to determine beforehand the angle and position of the roofing element to be cut. Indeed, the position of the roofing element positioned at the end is determined by the fact that it must be attached to the last uncut roofing element on the side of the row; it is then that the roofing element can be pre-cut according to an angle measured between a hip or valley and the adjacent roof overhang.

[0029] In a particular embodiment, the angle is determined according to the percentage of slope of the roof section on which said roofing element is intended to be laid.

[0030] Thus, such a cutting method makes it possible to obtain a reduction in the loss of raw materials, while having a more precise cutting.

[0031] In a preferred embodiment, the position is determined according to the length of the ridge.

[0032] The length of the ridge can be crucial in determining the position of the roofing elements intended to be placed at the ends, namely the roofing elements to be cut. Indeed, each row of roofing elements contains a specific number of roofing elements that is greater than the number of roofing elements in the rows above, which impacts the cutting of said roofing elements positioned at the ends of said rows.

[0033] Generally, the slopes or sides are respectively in the form of a hip, which may be triangular or trapezoidal in shape; thus, the row The roofing elements that are laid on the overhang of the roof contain the greatest number of roofing elements; the more the number of rows increases and therefore approaches the top of the roof, the fewer roofing elements there are in a row.

[0034] In a preferred embodiment, the position is determined according to the width of the cover element.

[0035] The position of the cut on the roofing element may depend on the width of the roofing element to be installed. Indeed, between different construction sites, the roofing elements used are of different dimensions and shapes.

[0036] In a particular embodiment, the angle is determined according to the thickness of the roofing element.

[0037] Indeed, overlapping roofing elements along the roof slope increase the angle between the roofing elements and, consequently, the angle between the ridge and the adjacent edge. Therefore, the slope of the roofing element must be considered less than the slope of the roof structure. The overlap positions the roofing elements more flat and reduces the angle between the roofing element and the horizontal. Due to the overlapping effect, roofing elements of a particular thickness affect the angle measurement.

[0038] In a preferred embodiment, the predetermined angle and position of the roofing element are measured, or transferred from a plan prior to the installation of said roofing element by determining its position on the roof and the angle separating a hip or valley and the adjacent roof overhang on which the pre-cut roofing element is intended to be installed.

[0039] In a particular embodiment, the predetermined angle is measured or transferred from a plan prior to the installation of said roofing element by determining the angles of the walls and the slopes of the roof on which the pre-cut roofing element is intended to be installed.

[0040] As a result, the production of ready-to-use roofing elements can be accelerated, while also improving the process of installing the roofing elements.

[0041] Preferably, the cover element comprises an assembly of at least two cover units connected to each other by a junction line.

[0042] More particularly, the assembly of at least two cover units is carried out by a gluing operation of two cover units together.

[0043] Thus, such a bonding makes it possible to obtain a more resistant assembly of cover units with greater flexibility of the materials in the face of temperature variations.

[0044] Furthermore, the assembly allows for installation by operators under all weather conditions.

[0045] In a particular embodiment, the assembly is carried out by a twinning operation. In other words, the two roof units share the same assembly line, which makes it possible to obtain better resistance of the roof elements.

[0046] Thus, the twinning operation can be carried out by any techniques known to the person skilled in the art concerned, for example gluing.

[0047] The joining line provides a reference point during cutting and installation. Indeed, the joining line is substantially perpendicular to the roof overhang when the pre-cut roofing element is placed on the roof slope.

[0048] In a particular embodiment, the predetermined angle is determined according to the type of material of the roofing element.

[0049] Depending on the different types of materials used, the cutting angle can be modified. Indeed, the slope of the roof section and the slope of the roofing elements may be different due to the mutual overlap of the roofing elements, which, depending on the material used, can affect the cutting angle to be determined.

[0050] According to one embodiment, the roofing element is configured so as to fit together with at least one other roofing element when the latter are used to cover a roof.

[0051] In another embodiment, the cover element includes a line that can be broken at an angle with an edge of said initial shape, said angle being determined by the position of the row and by said orientation.

[0052] Thus, instead of cutting out the entire cover element beforehand, the cover element can include a line, which can be broken by the operator, a line which follows the same line as the cutting line.

[0053] In a preferred embodiment, the cover element includes a cut-out. The cut-out is automatically formed over at least 2 centimeters on a cut end of the cover element.

[0054] More particularly, the end oriented towards the ground, when the roofing element is positioned on the roof slope to be covered.

[0055] The invention also relates to a method for cutting a cover element according to the invention.

[0056] Preferably, the automatic method includes at least the steps of determining an angle between a hip or valley and the adjacent roof overhang, determining the position of a row of the roofing element at the end of which said roofing element is to be positioned, and automatically and / or manually positioning a roofing element having a predetermined initial shape on a fixed support, the roofing element being positioned in a configuration dependent on the previously determined position, automatic and / or manual adjustment of a mobile cutting axis, automatically transferring the previously determined angle between the cutting axis and the fixed support and automatic cutting of the cover element.

[0057] According to a particular embodiment, the automatic method includes at least the steps of determining an angle between a hip or valley and the adjacent roof overhang, determining the position of a row of the roofing element at the end of which said roofing element is intended to be positioned, manually positioning a roofing element having a predetermined initial shape on a fixed support, the roofing element being positioned in a configuration dependent on the previously determined position, automatically adjusting a movable cutting axis, automatically transferring the previously determined angle between the cutting axis and the fixed support, and automatically cutting the roofing element.

[0058] According to a particular embodiment, the automatic method comprises at least the steps of determining an angle between a hip or valley and the adjacent roof overhang, determining the position of a row of the roofing element at the end of which said roofing element is intended to be positioned, automatically positioning a roofing element having a predetermined initial shape on a fixed support, the roofing element being positioned in a configuration dependent on the previously determined position, manually adjusting a movable cutting axis, automatically transferring the previously determined angle between the cutting axis and a fixed support, and automatically cutting or pre-cutting the roofing element.

[0059] Automatic cutting is carried out on a fixed cutting table with an orientation of the cover elements, placed on the cutting table by a placement system, the cutting angle is mobile because the cutting system is mobile in a linear way and not orientable to define the angle. Brief description of the figures

[0060] Other advantages and features of the present invention are now described by means of purely illustrative and in no way limiting examples of the scope of the invention, and from the accompanying drawings, in which the various figures represent:

[0061] [Fig-1] is a schematic representation of the pre-cut, ready-to-use cover element according to the invention.

[0062] [Fig.2] is a schematic representation of a roof on which the pre-cut roofing elements are intended to be placed.

[0063] In the following description, identical elements, by structure or by function, appearing on different figures retain, unless otherwise specified, the same references. Description of the implementation methods

[0064] With reference to [Fig. 1] to [Fig. 2], the present invention relates to a ready-to-use roofing element 1, intended to be placed at the edge of a roof, at the end of a row 6 of roofing elements 1, and to be positioned according to an orientation 10 defined by a hip 4 or a valley and the overhang 5 of an adjacent roof

[0065] The cover element 1 has a predetermined initial shape and this initial shape includes at least one cut and / or pre-cut forming an angle 2 with an edge of said initial shape, said angle being determined by the position 3 of the row 6 and by said orientation 10.

[0066] Fig. 2 represents a residential building comprising a roof with four roof sections 7 to be covered with roofing elements 1, including two slopes and two hips.

[0067] In order to cover the roof sections 7, and more specifically the ends of each row 6, it is necessary to cut these roofing elements 1 positioned at the ends so that they can be easily positioned on the roof section 7.

[0068] For this, it is necessary to determine the angle 2 of cutting and the position 3 or the cut according to the predetermined angle 2 is carried out on the cover element 1.

[0069] Thus, angle 2 is determined based on the measurement of several elements in order to obtain the most precise cut possible.

[0070] The angle 2 is determined by measuring, prior to the installation of the roofing element 1, the orientation 10 separating a hip 4 or a valley and the overhang 5 of an adjacent roof on which the roofing element 1 is intended to be installed, by measuring the percentage of slope of the roof section 7 on which the roofing element 1 is intended to be installed and by measuring the thickness of the roofing element 1.

[0071] Once the complete measurement of the cutting angle 2 has been carried out, the position 3 of the cut on the cover element 1 must be measured.

[0072] Therefore, position 3 is determined by the left or right end of the row 6 of roofing element 1 in which the roofing element 1 is intended to be placed on the roof, by the length of the ridge 4 and by the width of the roofing element 1.

[0073] Once the complete measurement of position 3 in which the cover element 1 will be cut and the cutting angle 2 has been obtained, then it is possible to automatically cut the cover element 1 so that the cover element 1 is ready for use by the operator.

[0074] Indeed, when the angle 2 of the cut is measured taking into account the length of the ridge 4, this angle 2 no longer changes, only the position 3 of the cut of the roofing element differs, depending on the row in which the roofing element 1 is intended to be placed.

[0075] Thus, it is sufficient to transfer these different position measurements according to the final position 3 of the roofing element 1 to obtain a multitude of pre-cut roofing elements 1 in order to obtain the complete coverage of a roof slope 7.

[0076] The ready-to-use cover element 1 is an assembly of two cover units connected to each other by a junction line 11.

[0077] Thus, the roofing element 1 is cut according to a position 3 and an angle 2 predetermined by measurements taken upstream of the cutting of the roofing element 1, said measurements being taken directly on the roof slope 7 to be covered.

[0078] The preceding description clearly explains how the invention makes it possible to achieve the objectives it has set for itself, namely to make the use of roofing elements 1 easier, adaptable to any type of roof, reducing the risks for site operators, all while improving the cutting accuracy of a roofing element 1.

[0079] In any event, the invention cannot be limited to the embodiments specifically described in this document, and extends in particular to all equivalent means and to any technically operative combination of these means.
