Description

Description Title of the invention: READY-TO-USE COVERING 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 of cutting said ready-to-use covering element. State of the art

[0003] In the field of roof covering, said roofs usually comprise several slopes covered with covering elements of dimensions which can vary from one to the other.

[0004] The junction between the different slopes and hips of the roof, at the level of the frame, is called a ridge when the junction is projecting or a valley when the junction is re-entrant. The ridge is therefore the junction between a slope and a hip, a hip and a hip or the junction between a slope and a slope, the valley is therefore the junction between a slope and a slope.

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

[0006] Therefore, the roofing elements around the valleys or ridges must necessarily be cut in order to be placed on the roof.

[0007] However, cutting roofing elements along the edge of the slope or ridge creates many 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 carries out the cutting on roofs with slopes ranging from 10° to 90° depending on the type of roof.

[0009] In addition, slopes can be slippery during adverse weather conditions and the handling of cutting equipment by the operator is difficult due in particular to their weight, which makes cutting roofing elements dangerous.

[0010] Furthermore, the time required to make these cuts is time when the operator is not carrying out other operations, therefore slowing down the covering of a roof.

[0011] Similarly, the operator may make a mistake in his measurements or miss his cut, causing unnecessary 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 site operators.

[0014] Furthermore, the invention is placed in a context of reducing the loss of raw materials, notably due to higher cutting precision. Presentation of the invention

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

[0016] Another subject of the invention is a method of cutting a covering 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 in an orientation defined by a ridge or valley and the overhang of an adjacent roof.

[0018] According to the invention, the covering 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 roof slope. In other words, the angle and position measurements are taken from the roof slope or from the construction plan, prior to the installation of the 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 covering element comprises an identification system making it possible to know the position of the covering element on a roof section, i.e. the predetermined row and the predetermined position of the covering element.

[0022] Still in the same sense, it is understood in the invention that the terms "initial shape" designate the shape of the covering element after its cutting or pre-cutting, on leaving the factory for example, but having been cut upstream of any installation operation, by transferring the angle measurements made upstream of the cutting.

[0023] Thus, it is understood that the invention is carried out by measuring the angle between an edge of said initial shape, said angle being determined by the position of the row and by said orientation, transfer for cutting or pre-cutting of this angle on a covering element. This latter operation being undertaken upstream of any installation of the covering element, which makes it possible to directly obtain ready-to-use covering elements, in the sense that the operator only has to place the covering elements in their position predetermined by the measurement of the angles. Consequently, before the operations of laying the covering elements, the operator has all the elements of already cut or pre-cut covers.

[0024] The term "at the end of a row" means the last two or more roofing elements at the ends of a row of roofing elements. In other words, on each end there may be two to three pre-cut roofing elements ready for use.

[0025] 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.

[0026] In a particular embodiment, the roofing element is a mechanical roofing tile.

[0027] Advantageously, a ready-to-use pre-cut roofing element according to the invention saves time on the installation of the roofing elements on the slope of a roof. Indeed, the fact that the operator no longer carries out the operations of measuring and directly cutting the roofing element makes it possible to carry out only the operations of installing the roofing elements.

[0028] A pre-cut cover element also provides increased safety for personnel at the workstation, and allows for installation regardless of weather conditions, provided that construction sites are accessible.

[0029] In addition, the fact that the roofing elements are cut before installation prevents the operator from taking risks when cutting them, while reducing the loss of raw materials thanks to more precise cutting of the roofing elements.

[0030] In order to obtain ready-to-use roofing elements, it is necessary to first determine the angle and position of the roofing element to be cut. In fact, the position of the roofing element positioned at the end is determined by the fact that the latter must be attached to the last uncut roofing element on the side of the row, it is then that the roofing element can be previously cut at an angle measured between a ridge or valley and the adjacent roof overhang.

[0031] In a particular embodiment, the angle is determined according to the percentage of slope of the roof section on which said covering element is intended to be installed.

[0032] Thus, such cutting allows for a reduction in the loss of raw materials, while having a more precise cut.

[0033] In a preferred embodiment, the position is determined according to the length of the ridge.

[0034] The length of the ridge can be decisive for determining the position of the roofing elements that are intended to be placed on the ends, namely the roofing elements to be cut. Indeed, each row of roofing elements contains a particular number of roofing elements which is greater than the number of roofing elements in the upper rows, which impacts the cutting of said elements. cover positioned at the ends of said rows.

[0035] Generally speaking, the sides or slopes are respectively in the form of a hip, which can be triangular or trapezoidal in shape. Thus, the row of roofing elements which is placed on the overhang of the roof contains the greatest number of roofing elements, the more the number of rows increases and therefore gets closer to the top of the roof, the more the number of roofing elements in a row decreases.

[0036] In a preferred embodiment, the position is determined according to the width of the cover element.

[0037] The position of the cutout 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.

[0038] In a particular embodiment, the angle is determined according to the thickness of the covering element.

[0039] In fact, overlapping roofing elements in the direction of the roof slope cause an increase in the angle between the roofing elements and consequently the angle separating the hip and the adjacent edge, so it must be considered that the slope of the roofing element will be less than the slope of the roof frame, the overlap positions the roofing elements more flat and decreases the angle between the roofing element and the horizontal. By overlapping effect, roofing elements of a particular thickness affect the measurement of the angle.

[0040] In a preferred embodiment, the predetermined angle and position of the roofing element are measured, or reported from a plan upstream of the installation of said roofing element by determining its position on the roof and the angle separating a ridge or valley and the adjacent roof overhang on which the pre-cut roofing element is intended to be installed.

[0041] In a particular embodiment, the predetermined angle is measured or reported from a plan upstream of the installation of said covering element by determining the angles of the walls and the slopes of the roof on which the pre-cut covering element is intended to be installed.

[0042] This allows for faster production of ready-to-use roofing elements and improved roofing element installation process.

[0043] Preferably, the covering element comprises an assembly of at least two covering units connected to each other by a joining line.

[0044] More particularly, the assembly of at least two cover units is carried out by an operation of gluing two cover units together.

[0045] Thus, such bonding makes it possible to obtain a more resistant assembly of roofing units with greater flexibility of the materials in the face of temperature variations.

[0046] In addition, the assembly allows for installation by operators under all weather conditions.

[0047] In a particular embodiment, the assembly is carried out by a twinning operation. In other words, the two roofing units share the same assembly line, which makes it possible to obtain better strength of the roofing elements.

[0048] Thus, the twinning operation can be carried out by any techniques known to those skilled in the relevant art, for example gluing.

[0049] The junction line is used to create a reference point during cutting and installation. In fact, the junction line is approximately perpendicular to the roof overhang when the pre-cut roofing element is placed on the roof slope.

[0050] In a particular embodiment, the predetermined angle is determined according to the type of material of the cover element.

[0051] Depending on the different types of materials used, the cutting angle can be modified. In fact, the slope of the roof face and the slope of the roofing elements can be different due to the mutual overlap of the roofing elements between them, which, depending on the material used, can have an impact on the cutting angle to be determined.

[0052] According to one embodiment, the covering element is configured to interlock with at least one other covering element when the latter are used to cover a roof.

[0053] In another embodiment, the cover element comprises a line breakable at an angle with an edge of said initial shape, said angle being determined by the position of the row and by said orientation.

[0054] Thus, instead of cutting the entire cover element beforehand, the cover element can include a line, which can be cut by the operator, a line which follows the same line as the cutting line.

[0055] In a preferred embodiment, the covering element comprises a chipping. The chipping is automatically obtained over at least 2 centimeters on a cut end of the covering element.

[0056] More specifically, the end facing the ground, when the covering element is positioned on the roof section to be covered.

[0057] The invention also relates to a method of cutting a covering element according to the invention.

[0058] Preferably, the automatic method comprises at least the steps of determining an angle between a ridge or valley and the adjacent roof overhang, determining the position of a row of the covering element at the end of which said covering element is intended to be positioned, automatic and / or manual positioning of a covering element having a predetermined initial shape on a fixed support, the covering element being positioned in a configuration dependent on the position determined beforehand, automatic and / or manual adjustment of a movable cutting axis, automatically transferring the previously determined angle between the cutting axis and the fixed and cutting support automatic cover element.

[0059] According to a particular embodiment, the automatic method comprises at least the steps of determining an angle between a ridge or a valley and the adjacent roof overhang, determining the position of a row of the covering element at the end of which said covering element is intended to be positioned, manually positioning a covering element having a predetermined initial shape on a fixed support, the covering element being positioned in a configuration dependent on the position determined beforehand, automatically adjusting a mobile cutting axis, automatically transferring the previously determined angle between the cutting axis and the fixed support and automatically cutting the covering element.

[0060] According to a particular embodiment, the automatic method comprises at least the steps of determining an angle between a ridge or a valley and the adjacent roof overhang, determining the position of a row of the covering element at the end of which said covering element is intended to be positioned, automatically positioning a covering element having a predetermined initial shape on a fixed support, the covering element being positioned in a configuration dependent on the position determined beforehand, 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 covering element.

[0061] Automatic cutting is carried out on a fixed cutting table with an orientation of the cover elements, placed on the cutting table by a positioning system, the cutting angle is mobile because the cutting system is mobile in a linear manner and not orientable to define the angle. Brief description of the figures

[0062] Other advantages and characteristics of the present invention are now described with the aid of examples which are purely illustrative and in no way limitative of the scope of the invention, and from the appended drawings, drawings in which the various figures represent:

[0063] [Fig. 1] is a schematic representation of the pre-cut, ready-to-use covering element according to the invention.

[0064] [Fig. 2] is a schematic representation of a roof on which the pre-cut roofing elements are intended to be placed.

[0065] In the following description, elements which are identical, by structure or by function, appearing in different figures retain, unless otherwise specified, the same references. Description of the embodiments

[0066] 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 covering elements 1 and to be positioned according to an orientation 10 defined by a ridge 4 or a valley and the overhang 5 of an adjacent roof

[0067] The cover element 1 has a predetermined initial shape and this initial shape comprises 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.

[0068] Figure 2 represents a residential building comprising a roof provided with four roof slopes 7 to be covered with roofing elements 1, including two slopes and two hips.

[0069] In order to cover the roof sections 7, and more precisely the ends of each row 6, it is necessary to cut these covering elements 1 positioned at the ends in order to be able to easily position them on the roof section 7.

[0070] For this, the cutting angle 2 and position 3 must be determined or the cutting according to the predetermined angle 2 is carried out on the cover element 1.

[0071] Thus, angle 2 is determined based on the measurement of several elements in order to obtain the most precise cut possible.

[0072] The angle 2 is determined by measuring, prior to the installation of the covering element 1, the orientation 10 separating a ridge 4 or a valley and the overhang 5 of an adjacent roof on which the covering element 1 is intended to be installed, by measuring the percentage slope of the roof section 7 on which the covering element 1 is intended to be installed and by measuring the thickness of the covering element 1.

[0073] Once the complete measurement of the cutting angle 2 has been carried out, the position 3 of the cutting on the cover element 1 must be measured.

[0074] Therefore, position 3 is determined by the left or right end of row 6 of covering element 1 in which covering element 1 is intended to be laid on the roof, by the length of ridge 4 and by the width of covering element 1.

[0075] Once the measurement of the position 3 in which the cover element 1 is to be cut has been completed and the cutting angle 2 has been obtained, it is then possible to automatically cut the cover element 1 so that the cover element 1 is ready for use by the operator.

[0076] In fact, when the cutting angle 2 is measured taking into account the length of the ridge 4, this angle 2 no longer changes, only the position 3 of the cutting of the covering element differs, depending on the row in which the covering element 1 is intended to be installed.

[0077] Thus, it is sufficient to report these different position measurements according to the final position 3 of the covering element 1 to obtain a multitude of pre-cut covering elements 1 in order to obtain the complete covering of a roof section 7.

[0078] The ready-to-use cover element 1 is an assembly of two cover units connected to each other by a joining line 11.

[0079] Thus, the covering element 1 is cut according to a position 3 and an angle 2 predetermined by measurements taken upstream of the cutting of the covering element 1, said measurements being taken directly on the roof section 7 to be covered.

[0080] The foregoing description clearly explains how the invention makes it possible to achieve the objectives it has set itself, namely making the use of roofing elements 1 easier, adaptable to any type of roof, reducing the risks for site operators, all while improving the cutting precision of a roofing element 1.

[0081] 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 effective combination of these means.
