Description

Title of the invention: Insulation retention brick

[0001] The present invention relates to the field of constructions and more particularly to the field of construction elements.

[0002] Bricks are generally parallelepiped unit elements commonly used by stacking in association with a binder in the construction of buildings. Depending on their destination, these bricks are likely to be solid or, alternatively, hollow by integrating one or more through housings.

[0003] These housings integrated into the thickness of the hollow brick are thus likely to be used in the context of optimizing the insulation qualities of the brick, both heat-insulating and acoustic. The through-housings of the bricks thus form receptacles for inserting an insulating material prior to the integration of the brick into a construction. Portions of insulating material of dimensions and shapes complementary to those of the housing are thus installed in each of the different housings of a brick. These portions of material are thus held in position by shear stresses that the interior walls of the housing exert against the surfaces of the insulating material.However, although a precise cut is made to the different portions of insulating material to be integrated into the brick, the industrialization of these cutting operations leads to slight variations in thickness between the different copies of the same portion of insulation produced. Also, taking into account, on the one hand, the clearances likely to exist between the portions of insulating material inserted and their housings and, on the other hand, the through nature of these housings between two opposite faces of a brick, it sometimes happens that the handling of these bricks leads to an accidental displacement of the insulating material in its housing, or even detaches the insulating material from its housing.

[0004] Also, the present invention aims to overcome these drawbacks by proposing a solution which makes it possible to optimize the maintenance of an insulating material inserted in the dedicated housing of the brick by compression and / or shear stresses while overcoming the dimensional differences likely to exist between the insulating material and its housing.

[0005] The invention thus relates to a terracotta brick comprising at least two opposite faces arranged parallel to each other and at least one housing passing through from a first face to a second face, characterized in that at least one interior wall of the housing comprises at least one relief.

[0006] The invention will be better understood, thanks to the following description, which relates to different preferred embodiments, given by way of non-limiting example, and explained with reference to the appended schematic drawing, in which:

[0007] [Fig.l] represents a schematic illustration of an example of a brick according to the invention seen from one of the faces carrying internal housing orifices capable of receiving an inserted element.

[0008] The invention thus relates to a terracotta brick 1 comprising at least two opposite faces 2 arranged parallel to each other and at least one housing 3 passing through from a first face to a second face, characterized in that at least one inner wall 4 of the housing 3 comprises at least one relief 5 capable of cooperating with an element inserted in the housing 3 to hold it there. This relief 5 positioned at the level of an inner wall 4 of a housing 3 operates a localized reduction in the width of this housing 3. Also, in the event of a possible dimensioning defect of the element inserted in the housing 3, the relief 5 is able to complete the missing length of the dimension of the inserted element to interact with the surface of this inserted element.The element inserted into the housing 3 of the brick 1 is thus clamped or pinched between, on the one hand, a part of the inner wall 4 of the housing and, on the other hand, the relief 5 positioned opposite this part of the wall 4 of the housing 3. In this way, the relief 5 forms a support point against the surface of the inserted element, so that the inserted element experiences shear stresses both at the level of the interaction of the relief 5 with the inserted element but also at the level of the part of the wall 4 of the housing 3 opposite. These shear stresses are then able to maintain the inserted element in position inside the housing 3.

[0009] Furthermore, it should be noted that, by forming a localized reduction in the width of this housing 3, the relief 5 carried by the wall 4 of the housing 3 is able to allow an inserted element to be held in position by compensating for its dimensioning defect without preventing the insertion of a correctly dimensioned element. Indeed, the thickness of the relief 5 relative to the surface of the inner wall 4 of the housing 3 is sufficient to compensate for a dimensioning defect of an inserted element. However, the relief 5 has a sufficiently localized arrangement and positioning so that the presence of this relief 5 is negligible to prevent or even slow down the insertion of a correctly dimensioned element into the housing 3.At most, such a relief 5 increases the contact surface of the inner wall 4 of the housing 3 against the surface of the inserted element and therefore the shear stresses which allow the correctly sized element to be held in position inside the brick 1. This insertion of the correctly sized element into the housing 3 is also likely to be accompanied by a deformation of the surface of the inserted element under the effect of the pressure exerted by the relief 5 bearing against the surface of the inserted element.

[0010] According to an example relating to an alternative embodiment of the brick of the invention, the at least one relief 5 has a substantially constant profile according to a substantially rectilinear axis oriented along the axis of the housing 3 passing through the brick 1. This particular arrangement of the relief along the housing 3 thus makes it possible to interact with the inserted element over its entire length, so that the shear stresses exerted by the relief 5 on the inserted element are greater than in the case of a point relief 5. It should also be noted that a brick 1 whose interior housing 4 carries a rectilinear relief 5 has the advantage of being easily produced by extrusion of terracotta. Thus, bricks 1 according to this variant of the invention are capable of being produced without difficulty from existing machines, in particular from a drawing machine, by simply modifying the extrusion profile of the die.

[0011] According to an example relating to another alternative embodiment of the brick of the invention capable of being combined with the previously detailed alternative embodiment, the inner wall 4 of the at least one through housing 3 comprises at least two surfaces 4a, 4b arranged opposite one another, each of these surfaces comprising at least one respective relief 5. According to this construction variant, compensation for the dimensioning defect of the inserted element is thus carried out by each of the reliefs 5 carried by the two surfaces 4a, 4b of the wall 4 opposite one another. Also, the reliefs 5 opposite one another are able to carry out double compensation for the defective dimensioning of the inserted element according to the same plane or the same dimension of the housing 3.The reliefs 5 carried by the surfaces 4a, 4b of the inner wall 4 facing each other thus achieve a clamping or pinching of the inserted element at the level of opposite faces of this element. Such clamping or pinching thus makes it possible to generate shear stresses on these faces of the inserted element so that it is held in position inside the housing 3.

[0012] According to an example relating to another alternative embodiment of the brick of the invention capable of being combined with the previously detailed alternative embodiments, in a plane in section substantially parallel to the opposite faces of the brick 1, the at least one relief 5 has a convex arrangement having the shape of a portion of a circle. Such a construction of the relief 5 has the advantage of corresponding to an arrangement that is simple to produce. Of course, while remaining within the scope of the invention, other arrangements or forms of relief 5 are likely to be envisaged to interact by pressure or by bearing against one of the surfaces of the inserted element. However, unlike an angular and / or tapered shape, the rounded shape gives the relief 5 improved solidity so that the end of the relief 5 is more resistant to the risks of breaking the terracotta of the brick.Furthermore, unlike an angular and / or tapered shape, a rounded relief 5 causes limited degradation of the inserted element when it is inserted into the housing 3 of the . brick 1. Indeed, an angular or tapered relief would be likely to alter or cut the inserted element, particularly when the material of this element is friable, fibrous and / or of fragile consistency.

[0013] According to an example relating to another alternative embodiment of the brick of the invention capable of being combined with the previously detailed alternative embodiments, the thickness of the relief 5 is between 2 and 5 millimeters relative to the surface of the wall 4 which carries the relief 5. Preferably, such a relief 5 has a thickness of the order of 3 millimeters. However, it should be borne in mind that the thickness of this relief 5 is capable of being adjusted according to the material which constitutes the inserted element and the sizing variability capable of affecting the inserted element. Similarly, the thickness of this relief 5 is capable of being adjusted according to the possible presence of a similar additional relief 5 positioned opposite inside the housing 3.

[0014] According to an example relating to another variant embodiment of the brick of the invention capable of being combined with the previously detailed variant embodiments, in a sectional plane substantially parallel to the opposite faces 2 of the brick 1, the at least one through housing 3 has a substantially rectangular shape, each of the facing surfaces 4a, 4b of shorter length comprising at least one relief 5 positioned facing its counterpart relief 5. Unlike other shapes, in particular circular or triangular, the rectangular sectional shape of the housing 3 has the advantage of being adapted to a format of element intended to be inserted which is easy to produce. Furthermore, preferably, the sectional shape of the housing 3 is substantially constant along the thickness of the brick 1.In addition to allowing the insertion of an element whose parallelepiped shape is simpler to manufacture, this preferred construction also has the advantage of being easily achievable in the context of brick production 1 by extrusion.

[0015] According to an example relating to another variant embodiment of the brick of the invention capable of being combined with the variant embodiments detailed previously, in a sectional plane substantially parallel to the opposite faces 2 of the brick 1, the at least one through housing 3 has a substantially rectangular shape, each of the longer facing surfaces of which comprises at least one relief positioned facing its counterpart relief.

[0016] It should be noted that the at least one through-housing 3 is likely to comprise reliefs 5 at several surfaces of the inner wall 4 of this same housing 3. Similarly, the at least one through-housing 3 is likely to comprise several reliefs 5 at the same surface of the inner wall 4 of this same housing 3.

[0017] According to an example relating to another alternative embodiment of the brick of the invention capable of being combined with the previously detailed alternative embodiments, the at least one through housing 3 comprises at least one insulator held inserted inside the housing 3 by at least one relief 5 of the inner wall 4 of the housing 3. Also, the element inserted into the housing corresponds to an insulator. This insulator is thus held in a housing 3 of the brick 1 so as to be positioned in compression between at least two opposite surfaces 4a, 4b of the inner wall 4 of the housing 3, at least one of the two surfaces 4a, 4b of which comprises at least one relief 5 bearing against the surface of the insulator so as to exert shear stresses thereon.

[0018] According to an example relating to a particular variant of the previously detailed embodiment variant, the at least one insulator has an elastic property allowing compression deformation. This property thus allows insertion of the insulator into a housing 3 of the brick 1 in a compressed or crushed form in a plane substantially perpendicular to the axis passing through the housing 3, so that, once in position inside the housing 3, the insulator resumes its expanded form and presses against at least two opposite surfaces 4a, 4b of the housing 3, at least one of which comprises a relief 5.

[0019] According to an example relating to a particular variant of the previously detailed embodiment variant, the at least one insulator has at least part of its composition of biosourced origin which, in addition to its environmental and renewable interest, is capable of improving the quality of the air naturally circulating in the dwellings 3 of the brick 1.

[0020] According to an example relating to a particular variant of the previously detailed embodiment variant, the at least one insulator has a composition comprising at least one material of the wood wool or wood fiber type. However, complementary or alternative materials are also likely to be used such as sheep wool, hemp wool, cotton wool, cellulose wadding from paper, duck feathers but also cork, straw, linen, or even recycled textiles. It should be noted that the majority of insulators made from such bio-sourced materials have the advantage of elastic properties allowing their deformation in compression.

[0021] Of course, the invention is not limited to the embodiments described and shown in the attached drawing. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
