Description
A building block in the form of an angle profile, and its use for assembling a residential structure.
[0001] The present invention relates to the field of construction walls, enabling the construction of robust buildings. More particularly, the invention relates to a building block for forming a right angle in a prefabricated dwelling and also concerns a partition wall arrangement for a prefabricated dwelling, including such building blocks. A method for assembling structural members and at least one building block forming a right angle, using a dry construction process, is also proposed for the construction of all or part of a dwelling.
[0002] The construction of walls by simply stacking blocks on top of each other has a long history. Once the concrete blocks are transported and placed on site, the walls are assembled up to the height of one story. This technique involves stacking prefabricated concrete blocks on top of each other and then pouring a fluidized concrete into the central part of these blocks, which have openings. This concrete then spreads throughout the structure, creating a rigid framework. Interlocking ends are generally incorporated into the blocks, which helps to stiffen the entire structure and prevent deformation during the concrete pouring process.
[0003] For the construction of passive houses or dwellings, a technology known as insulated concrete forms (ICF) is used. This technology was developed to minimize on-site assembly time while providing thermally insulating layers. Workers use a two-walled system, each wall composed of interlocking panels of thermally insulating material. These panels are made of a plastic material filled with air bubbles, such as expanded polystyrene foam. The space between the outer and inner walls allows for the pouring of a concrete wall. Historically, these blocks were primarily used for foundation walls, but many builders are now extending their use to include walls above ground level in one-, two-, or three-story houses.
[0004] In the field of prefabricated and thermally insulated building construction, it is common practice to use modular elements manufactured in a factory and assembled on-site by combining different polystyrene components to form a double wall. The drawings in US document 20050155306 illustrate a typical arrangement of modular elements, which also allows for pouring concrete into the corners. Pouring concrete into the hollows of the blocks or the spaces between the panels, including in the corner sections of the building, makes the process delicate and necessitates mixing fresh concrete on-site. Vertically positioned steel bars or rods are used to reinforce the walls.
[0005] Document FR 2951206 describes, for example, the use of prefabricated, interlocking composite panels, possibly including expanded polystyrene for the solid core of each panel. Each panel also has a layer of ceramic and / or cement on the flat or curved surfaces. This type of design allows for the creation of thermally insulated walls. However, reinforcement is required, and the ceramic and / or cement layer must be poured during the manufacturing process.
[0006] Regardless of the wall design chosen, it's important to note that one of the defining characteristics of all houses and similar dwellings is the corner. Meeting mechanical strength requirements while achieving high energy efficiency (without thermal bridges), for example, can be challenging with CIB technology. Furthermore, the pouring process makes: - expensive panels if such operations are required at the time of panel manufacturing; - the site is particularly dirty, with slowness and tedious handling, if these pouring operations are planned on site.
[0007] There is therefore room for improvement, in order to be able to carry out projects quickly and efficiently while minimizing the use of complex operations. The wall arrangement described in document WO 2009 / 087593 proposes vertically stacking profiles of insulating material and inserting thin metal rails, with the base of these rails positioned vertically, into a groove in the upper part of the insulating material that opens from above. This type of arrangement is unsuitable for use with solid components made of / from concrete, for example, beams or similar structural masonry components that may form part of a masonry ring beam or bond beam (peripheral bond beam, typically horizontal).
[0008] In order to overcome one or more of the problems mentioned above, the invention proposes a building block, typically prefabricated, adapted to form an angle profile (rigid) which can be placed for example in the corners of a dwelling and which facilitates the installation of walls, including construction panels, in a completely dry process.In particular, a two-sided connecting corner profile for construction panels is proposed, adapted to form a corner of a residential structure, the corner profile extending along a longitudinal axis between a first axial end and a second axial end, being provided with several cavities, including two elongated parallel cavities which communicate, for example directly, with two end cavities, opposite each other, adapted for the placement of two rigid components such as a post and at least one beam, preferably allowing a three-dimensional arrangement (along three orthogonal directions) of the components.
[0009] The corner profile, which can thus include two cavities, elongated along the longitudinal axis and accessible laterally from one of the two sides, is made, for example, of the same thermally insulating cellular plastic material and includes: - a first part (forming a dorsal / back part), elongated longitudinally and presenting or including an L-shaped cross-section, allowing the two elongated cavities to be delimited externally; - a second, longitudinally elongated part that allows the two elongated cavities to be delimited internally; and - a central core of the angle profile, elongated along the longitudinal axis and including two opposite axial faces, the central core connecting the first part to the second part.
[0010] The first and second parts can also be used to delimit, between them: - one or two end cavities, each axially delimited by one of two opposite axial faces and opening laterally on each side to house the ends of two rigid structural components, preferably made of concrete, elongated and arranged at 90° to each other. At least one of the components whose end is housed in the end cavity extends perpendicularly to the longitudinal direction of the profile. One of these components may be a beam block (of constant cross-section) obtained from: - of a prefabricated beam (a high beam, for example), and - a complementary / keyed joint part, filling the end cavity and able to form a right-angle joint with another prefabricated beam (top beam for example). Preferably, one of the first end cavity and the second end cavity is a cavity for housing a beam end which is made of concrete and formed directly on (and thus superimposed on) the corresponding axial face of the central web.
[0011] This allows for a relatively simple corner piece design, for example, made of a single material, facilitating the assembly of panels, beams, and columns that can be inserted vertically into the long (elongated) cavities between a corner profile and an adjacent construction panel. All wall components can be prefabricated. The end cavity(es) allow for axial and / or lateral connections between rigid structural components, strengthening the building's framework and helping to prevent thermal bridging. Furthermore, alternating concrete with a different insulating and resistant material (for example, expanded polystyrene) can make the structure particularly resistant to shocks during earthquakes.
[0012] The corner profile can assemble, preferably in a single piece, the first part, the second part and the central core, with optionally the first and second parts delimiting each other: - a first end cavity axially delimited by one of the two opposite axial faces, and opening laterally on each of the two sides to allow the end of a first beam to be received; and - a second end cavity axially delimited by a second of the two opposite axial faces, and opening laterally on each of the two sides to allow the end of a second beam parallel to the first beam to be received (for the guidance and / or assembly of one or more construction panels on one of the two sides).
[0013] The angle profile is well suited for the construction of a residential structure using dry construction methods (without the need to pour concrete into formwork), while allowing for the easy insertion or fitting of modular / prefabricated elements, including beams, ensuring the solidity of the structure.
[0014] Concrete incorporated into or forming part of prefabricated vertical elements can be easily placed within the walls of the residential structure. A prefabricated concrete column (possibly vibrated concrete or similar) can extend from a lower beam (forming a buttress, for example, offset laterally on one side of the column) to a higher beam and along the central web, once the corner profile is positioned vertically, and / or extend longitudinally (also along the central web) so as to pass through three of the four cavities in the corner profile. Preferably, two (concrete) columns can be directly inserted into the corner profile, filling the elongated cavities, flush against the central web on both sides for the assembly of the building panels.
[0015] The angle profile allows for the lateral wrapping / covering of at least one, and preferably two, prefabricated vertical columns on two sides of the central web, before the construction panels are placed along these columns. More generally, the angle profile facilitates the easy installation of rigid structural components, typically made of concrete, by defining receiving cavities whose geometry and dimensions are adapted / adjusted for the placement of these respective components in three orthogonal directions: X, Y, Z. It is possible to distribute columns (vertical uprights) very close to the web of the angle profile, in a corner of the structure, such as a passive house or similar passive residential building. The wall sections can simply be assembled from prefabricated elements, without the need for concrete pouring.These support, guidance and interlocking or similar interconnection functions of construction panels, combined in a single building block, allow the rapid assembly of thermally insulating modular construction panels, designed for example with the same material as the corner profile.
[0016] The angle profile also allows for keyed connections at one of the end cavities, within a gap left between adjacent components, so mortar can cover protruding reinforcement ends provided on certain structural components. A central sub-volume of the upper end cavity can thus be filled with such mortar to form the 90° connection between two high beams, if necessary also encasing the ends of the reinforcement that are left exposed in one and / or the other of the two columns (housed in two elongated cavities) which are flush with the top of the central web at their upper end, before the mortar is poured.
[0017] Each panel (possibly between 1 and 2 meters wide, for example approximately 1.5 m) can be easily curved using four rigid concrete components, including the panel adjacent to the profile forming the angle in the structure. No reinforcing piece is required. The finishing can be done simply against the main faces of the construction panels, which are flush with the faces of the columns and beams.
[0018] Thanks to the angle profile, a high end cavity is available (also accessible from above / following the longitudinal direction of the profile) after filling the elongated cavities, knowing that one can, for example, mount successively (vertically): - a first post, - the angle profile with the first post received (at least partially) in the first elongated cavity, and - the second post housed at least partially in the second elongated cavity. The upper end cavity associated with the two elongated cavities offers the advantage of being able to reliably connect two upper beams, as soon as these upper beams have been installed at the end of the assembly of a wall section including construction panels.
[0019] The end cavity opens laterally on both sides and, in the assembled state of the angle profile, forms a high end cavity with an opening width of at least 70 or 120 mm and / or equal to the width of the underlying elongated cavity. The two prefabricated top beams can be placed side-by-side with the panels, for example, in the upper grooves of these panels, and rest (at their ends) on one of the corresponding posts, at the same height level as a lateral opening of the end cavity. This then allows these two top beams to be easily joined, optionally by keying, at the end of the assembly to form a rigid, horizontal, L-shaped structural section. This type of connection is made in an area offset towards the corner relative to the panels, after the connected construction panels have been installed on both sides of the profile.
[0020] One particular feature of the corner profile is that it is manufactured as an interlocking building block, for example, at least four or five times longer than it is wide. The width, for instance, is greater than 25 cm, and possibly at least 35 or 40 cm. The former is typically an outer section of the profile, wider than the latter, defining the width dimensions of the cross-section and thus incorporating a larger quantity of material. thermally insulating than the second part designed as the inner part of the profile (whose cross-section is located, at least in part, inside the rectangular, for example square, section corresponding to the two branches of the first part).
[0021] In manufacturing options, the corner profile is made of expanded polystyrene, polyurethane, or another foam material with a thermal conductivity of 0.040 W / (mK) or less, preferably 0.038 W / (mK) or less, produced from a cut parallelepiped block, for example, by milling. The minimum thickness of the corner profile at mid-length (along the longitudinal axis) is greater than 250 mm, preferably 290 or 300 mm or more. For example, excluding the end profiles with end cavities, the thickness of the central core and the first section add up to exceed 300 or 350 mm.
[0022] In some embodiments, the angle profile has one or more of the following characteristics: - the part constituting the angle profile is a cut block. - the part forms a support for casting, in each end cavity, a beam, a non-metallic contoured element or similar structural component. - the angle profile has a length (forming a height in the installed state) greater than 2 meters with a continuous central web (belonging to a single piece) between the two cavities. - the section of the angle profile is inscribed in a square whose width coincides with two dimensions of the outer part, which has an L-shaped cross-section. - the second, outer part of the block includes two outer portions or branches connected at a right angle. - the central soul is full. - the central core corresponds to a common projection from each of the first two inner faces formed by the first part (the first / outer part can also form / define two outer lateral faces of the angle profile which are perpendicular to each other extending parallel to the longitudinal axis. - an inner sub-block forms the central core, through which passes a central axis of the profile, the central axis being located at the intersection of a first median longitudinal plane passing through the first part, the central core and the second part and a second longitudinal plane, perpendicular to the first longitudinal plane, which passes through two ends of the first part which constitute free edges on both sides of the profile. - the sub-block forming the central core is set back in three or four directions from the L-shaped section forming the first part (outer L-shaped section), so as to form the bottom of three or four cavities (The concrete beams and columns can thus be inserted and / or extended into such cavities, being partially enveloped by the first part). - the second part is an elongated inner part, for example of the same length as the first part, which allows to form two returns at 90°, from a lateral face of the sub-block / central core. - each of the returns forms an elongated face parallel to the longitudinal axis and opposite a corresponding portion (in an internal face) of the two outer portions / branches of wrapping that make up the first part. - the central core of the profile is set back to form the bottom of the long cavities and the bottom of one or two end cavities delimited between the first and second parts. - the first part or inner part is of the same length (measured along the longitudinal axis) as the second part or outer part, separated from the first (outer) part by the central core which has a four-sided section, for example rectangular or square. - a respective sub-volume of at least one end cavity (low end cavity for example) is adapted to be filled by a corresponding end of a rigid column including concrete, while the complementary sub-volume of the same end is adapted to be filled / occupied by an end of a beam including concrete or by joining material at such an end, and joining (laterally and / or axially) the column, so that the column and the two beams form a U-shaped concrete assembly.
[0023] According to one particular feature, the corner profile includes interconnecting means, preferably with interlocking tabs, for connection to the construction panels. These interconnecting means are selectively distributed on both sides of the profile, outside of the respective cavities within the profile. Preferably, these interconnecting means do not project axially from the rest of the corner profile (along the longitudinal axis) and may be integral with the block of cellular plastic material constituting the profile. In some options, each side of the corner profile is equipped with interconnecting elements that can be rigid / non-deformable (not forming clips, for example) for interconnection with additional connecting elements provided on the construction panels, typically on the edges of these panels, so that each of the two posts (vertical when assembled) can be sandwiched between the corner profile and an adjacent construction panel on one side. The interconnection does not create any protrusion beyond the thickness of the panels.
[0024] Optionally, the interconnection means may extend over most or all of the largest dimension of the angle profile, these means being distributed on both sides of the profile by being distributed on the first (outer) part and on the second (inner) part for each of the two sides.
[0025] To allow the connection of panels, the corner profile may have one or more of the following features: - the profile has four connection regions for connection / attachment to construction panels. - the four regions are provided with tongues or interlocking reliefs, and are distributed in pairs on each of the two sides of the angle profile, on either side of a corresponding cavity among the elongated cavities.
[0026] According to one particular feature, the first and second end cavities are L-shaped and have the same lateral opening width measured perpendicular to the longitudinal axis on both sides. This L-shape may alternatively be provided for only one end cavity, adapted to form the upper end cavity in the assembled / erected state of the angle profile. The opening width may be between 120 or 140 mm and 300 mm, preferably between 150 and 210 mm. Independently or in combination with the above, the first and second end cavities have a height, possibly identical, measured parallel to the longitudinal axis, that is greater than 140 mm.
[0027] According to another feature, the elongated cavities are each delimited by a pair of faces (preferably continuous faces) which are parallel to each other and distributed in the first part and in the second part, having a depth greater than or equal to 90 mm, measured perpendicular to the longitudinal axis, to allow insertion of prefabricated structural columns (including concrete) and optionally based on the same material, preferably reinforced concrete, as the beams.
[0028] The posts, optionally with a square cross-section, can be dimensioned to fit partially into the elongated cavities so as to protrude on the corresponding side of the corner profile, for example, by an extension of at least 70 mm, approximately equal to the insertion depth in the elongated cavity. The depth of the elongated cavity can thus be between 65 and 115 mm, for adaptation to posts whose characteristic side dimension (square cross-section, for example) is between 130 and 240 mm, for example, approximately 180 mm.
[0029] In some options, the second part may have two opposing axial faces, each defining an area smaller than that of the corresponding face of the first part. These axial faces of the first and second parts may be coplanar (lying in the same termination plane of the building block constituting the angle profile; this termination plane may result from a straight cut perpendicular to the longitudinal axis). The axial faces of the central web are typically set back from each corresponding termination plane (setback of minus 25 or 30 preferably, for example around 35 mm). Alternatively, only one axial face of the central core is recessed.
[0030] According to one particular feature, the area of the opposite axial faces of the central core is identical. The central core can define two areas (by its opposite axial faces), each of which is greater than the area defined by the second part and less than the area defined by the first L-shaped section.
[0031] For a good compromise between the robustness of the panel assembly, the compactness, and the thermal insulation effect allowed by the angle profile which guides / allows the embedding of the posts, it is provided for example that the first part (back / wrap part) has a first thickness greater than or equal to 80 mm, preferably between 90 and 120 mm, while the central core can have a second thickness (central core thickness measured along the same direction as the first thickness) greater than the first thickness and between 140 and 320 mm.
[0032] The corner profile (in one piece) can consist of a single piece without any metallic components, for example, made of polystyrene, preferably expanded polystyrene. The cellular plastic material can essentially consist of expanded polystyrene with a density between 16 and 25 kg / m³ 3 More generally, it is possible to obtain a robust, rigid framework, suitable for resisting earthquakes, for example, while benefiting from the strength advantages of modular elements / blocks containing a structurally resistant thermal insulation material that traps air bubbles within its thickness. This allows for the formation of walls at right angles to each other, which are then fixed to a slab and a roof, typically by concrete elements (columns and beams).
[0033] The corner profile is compatible with a dry formwork system, without a cavity for concrete pouring. It is possible to construct buildings / structures / residential dwellings without using the CIB module technique. By eliminating this type of pouring, the numerous risks encountered during filling are avoided, particularly for the construction of columns, which cannot be made of vibrated concrete.
[0034] It is also permissible to obtain a residential structural arrangement allowing the assembly of rigid prefabricated components, such as concrete or reinforced concrete, directly onto an angle profile, thus simplifying the construction site. Such a residential structural arrangement, allowing the interlocking of building panels, includes: - in a corner (of the residential structure), the corner profile according to the invention / as above, mounted vertically, the first part and the second part delimiting between them one or two end cavities, formed at the opposite vertical ends of the profile when two end cavities are provided; - two (horizontal) beams distributed on both sides of the profile, mounted perpendicularly to each other, with two posts interposed between these two beams (the beams being low / stopper beams); - two other beams distributed on both sides of the profile, mounted perpendicularly to each other, and at least one of which is engaged or extended horizontally into the end cavity of the angle profile, which is an upper end cavity of the angle profile; and - the two posts mounted vertically by filling one and respectively the other of the two elongated cavities, each joining by each of its two axial ends one of the beams arranged on the same side among the two sides (with the possibility of a lateral or axial connection to the beam, optionally via a keying or sealing / anchoring); thanks to which the construction panels can be assembled on each of the two sides by being sandwiched respectively between two of the beams which extend horizontally on the same side at two distinct height levels, one of which corresponds to the height level of the end cavity.
[0035] Such an arrangement makes it possible to simultaneously satisfy the ever-increasing requirements for energy efficiency and mechanical resistance, with rapid execution of the construction site.
[0036] In some options, a single panel bridges the vertical gap between the corresponding lower and upper beams. In other variations, an assembly of at least two panels can form a panel sandwiched between the lower and upper beams.
[0037] One particular feature of the design is that it includes multiple construction panels (including the two panels) that define four sides of the quadrangular residential structure. The design may also include three additional corner profiles to form four corners of the residential structure, with the corner profiles being identical, for example. According to one option, at least one pair of the two beams and the other two beams are beams forming part of a masonry belt (horizontal belt).
[0038] Optionally, all or part of the construction panels, which are preferably of the same height, have a maximum height equal to the height of each of the corner profiles. The construction panels may have a three-layer structure, with an intermediate layer set back (relative to the other two layers) and the same thickness as the central web of the corner profiles, while the other two layers may have a thickness corresponding, respectively, to the thickness of the first part of the profile and the thickness of the second part of the profile.
[0039] For example, by using a system assembled with four angle profiles, it is possible to easily create the side walls, with a distribution of prefabricated posts and beams, these elements (preferably made of reinforced / consolidated concrete) being, for example, chemically keyed.
[0040] During construction, recesses can be made in the slab for anchoring and sealing the columns (which may be reinforced with steel), while the beams can be easily keyed (e.g., chemically: keying or chemical anchoring) to the columns. Keying for the (lateral) connection of two precast reinforced concrete elements / components ensures the robustness of the assembly. Sealing mortar, for example, of the shrinkage-compensating type, can be introduced / poured into a small gap between the components to be joined, preferably a gap of 50 mm or less.
[0041] It is also proposed, from another perspective, to use angle profiles in a wall assembly process for the construction of a residential structure, facilitating the work of operators on the construction site. More specifically, it is planned to use an angle profile as described above in a process for assembling a side wall of a residential structure, in which the angle profile serves in the steps essentially consisting of: - mount the angle profile vertically, preferably on a horizontal concrete slab, by inserting a first post into one of the elongated cavities, so as to position the bottom of the first post in an adjacent position or against one end of a low beam which is part of two low beams extending horizontally at 90° to each other, on both sides of the angle profile; - insert a second post into the other of the elongated cavities of the angle profile, so as to position the bottom of the second post in an adjacent position or against one end of the other of the two lower beams; - to fit a construction panel onto each of the two sides of the profile (using a panel that has a general vertical extension with a lower groove into which the corresponding bottom beam is inserted), so as to make two construction panels directly attached to the corner profile by being placed against each of the posts; and - mount two high beams one perpendicular to the other, parallel to the two lower beams two by two, linking them laterally to a high end of a post, between the first post and the second post, arranged inside the end cavity of the angle profile which forms the high end cavity.
[0042] A method for assembling a unit with at least four corners, using a corresponding corner profile for each corner, can be implemented. Each wall / partition section is constructed by distributing the prefabricated building elements along the profiles. The angle profile (for posts) is positioned at the same height as the end cavities (for beams), sometimes by adding intermediate posts within a wall section. This allows for the economical construction of a thermally insulated wall. The specific cross-section of the angle profile facilitates this type of installation by preventing positioning errors and saving on construction steps, especially when the profile is manufactured as a single unit.
[0043] The thermal bridge advantages and the simplicity of installation make this type of angle profile attractive for the construction of passive houses / buildings.
[0044] According to a particular feature, at least one of the two upper beams is axially supported, at one of its ends, against one of the two columns, extending above the upper face of the central web, which forms one of the two opposite axial faces of the latter. Possibly, at least one of the following two relationships is satisfied: h2 + h3 = H h1 = h2 where H represents the height of the angle profile, h1 and h2 represent respectively a concrete height of the top and bottom (prefabricated) beams, measured parallel to the longitudinal axis, and h3 represents the largest dimension of the second column, possibly supplemented by thicknesses of junction regions with the beams.
[0045] The two construction panels, which are modular, can have opposing grooves (for beam wrapping) separated vertically by a distance equal to the spacing between a bottom beam and a top beam opposite the bottom beam. This distance can also be substantially equal to or close to the longest dimension of the columns. Optionally, the height of each of the two panels can be adjusted to match the height of the corner profile.
[0046] Compared to a prefabricated wall structure obtained through a known process, it must be noted that corner blocks made from a robust plastic such as expanded polystyrene minimize the amount of concrete strictly necessary for the solidity of the dwelling, in the form of posts and / or beams, while avoiding the preparation and pouring of concrete on site, without losing structural rigidity once the structural components are assembled using the corner profile.
[0047] Typically, two posts are positioned against the central web, occupying the elongated cavities along the longitudinal axis. For example, one of the posts may have a dimension greater than the length of the elongated cavity to extend (possibly by means of reinforcement elements) in the upper end cavity, and without protruding / projecting upwards beyond an end cavity of the angle profile.
[0048] The beams can each be, at their ends, fixed or chemically keyed to: - a lateral or axial face of a post, housed in an elongated cavity and whose length / greatest dimension is equal to or less than that of the angle profile (L-shaped connection of the beam); and / or - an axial face at the end of the post, whose length / greatest dimension coincides or is flush with the extension of the elongated cavity (T-connection of the beam, knowing that the beam in question runs along an axial face of the central web, beyond this post).
[0049] This process, using posts wrapped with an angle profile arranged longitudinally in the same direction as the posts, is compatible with rapid, dry assembly of structural components, with easy positioning / anchoring / sealing of beams, compatible with a wide variety of construction panels, typically modular.
[0050] Advantageously, the beam and the column can have the same perimeter in cross-section view. Optionally, the perimeter of the beams and columns is preferably constant and / or predefined with a given width to correspond substantially to the spacing defined by the elongated cavities and the access section on one side of each end cavity (spacing as seen in a cross-sectional view of the profile). Brief description of the drawings
[0051] Other features, details, and advantages of the invention will become apparent from the detailed description below and from the analysis of the accompanying drawings, which are given by way of non-limiting examples and on which: - Figure 1 shows an angle profile suitable for connection with modular construction panels mounted vertically from two different sides of the profile, turned at 90; - Figure 2 is a perspective view illustrating an example of assembly of reinforced concrete components that can be coupled to the angle profile of Figure 1 and joined to each other, the construction panels being omitted for illustrative purposes; - Figure 3 is a perspective view of the angle profile of Figure 1, just after cuts which made it possible to obtain the different cavities; - Figure 4A is a perspective view of a first example of a quadrangular structure whose walls are composed of prefabricated elements, including angle profiles conforming to the invention at the angles; - Figure 4B is a perspective view of a second example of a quadrangular structure whose walls are composed of prefabricated elements, including corner profiles conforming to the invention at the corners. Description of preferred embodiments
[0052] The drawings are provided by way of example and are not intended to limit the invention. They are schematic representations of the principle intended to facilitate understanding of the invention and are not necessarily to scale with practical applications. In particular, the dimensions of the various parts (length shortened for illustrative purposes) may not be representative of reality. In the various figures, identical reference numerals indicate identical or similar elements.
[0053] Referring to figures 1 to 3, one embodiment of the connector profile, referred to hereafter as angle profile 1, is shown, intended to allow a junction between construction panels 41, 42. These panels 41, 42, here prefabricated for example, are constituents of two adjacent wall sections of a residential structure such as a house or building.
[0054] The angle profile 1 is generally elongated along a longitudinal axis Z1 and has a structure whose cross-section is identical over most of its length, for example identical except for the two opposite ends E1, E2 of the profile 1. More particularly, the profile 1 may have a first part 10 and a second part 20, parallel along the axis Z1 and adapted to delimit between them two cavities C1, C2 oriented at 90° to each other, so that these parts 10, 20 define two sides 2, 3 of a 90° angle junction. The angle profile 1 has, along the Z direction of the longitudinal axis Z1, a dimension much larger than the other two extension dimensions provided for its cross-section, in the (XY) plane visible in Figure 1. As a non-limiting example, the angle profile has a length much greater than 1 meter, preferably greater than or equal to 2 meters.
[0055] Profile 1 is provided with two long cavities C1, C2 on both sides 2, 3, which can be accessed at least laterally (from one of the sides 2 or 3 of profile 1), these cavities C1, C2 being directly delimited each by: - a flat portion of the first part 10 (outer part, back), elongated longitudinally, knowing that the first part has an L-shaped cross-section forming two flat faces arranged at 90° to each other; - another flat portion opposite, belonging to the second part 20, also elongated longitudinally and which may have a rod-like shape, relatively thick; and - a flat portion of the base which belongs to a central web 30 of the profile 1, this central web 30 being able to be shorter than the two parts 10, 20.
[0056] It is understood that the flat faces complement each other to form a U shape in cross-section view, thus delimiting the two cavities C1, C2 which open laterally on one side only, so that the angle profile 1 can wrap around an elongated rigid component such as a post 13, 13' on both sides 2, 3 with an effect of embedding (complete or partial) of the post 13, 13' in the profile 1.
[0057] The angle profile 1 has its largest dimension adapted to extend vertically along the height of a residential floor, for example, between the level of a slab D to form or support the floor on that floor (see Figure 4A, for example) or other foundation component, and a portion of the ceiling of that same floor. Referring to Figures 2 and 3, the angle profile 1 has its largest dimension corresponding to a height H and is designed and arranged to accommodate all or part of two uprights or columns, which may be made of concrete, for example, reinforced concrete, here consisting of two simple columns 13, 13', one of which (column 13 in Figure 2) may have the same length as the angle profile 1.
[0058] The first part 10 of the angle profile 1 includes two long portions (orthogonal in cross-section view) defining an internal angle, here approximately 270°, with the first part 10 having the same length / height H as the entire piece or building block constituting the angle profile 1. This first part 10, composed of two portions, has an L-shaped cross-section to define a 90° angle between the two planar portions, the 90° angle being internal with respect to the internal angle of 270°, typically delimited by the external faces of the first part 10. It is understood that the first parts 10 of four identical or similar angle profiles 1 can form four external corner zones (with internal angles) in the floor constituting the residential structure, as seen, for example, in Figure 4A.The two flat portions of the first part 10 have a constant thickness over a certain width d10, forming all or part of the width of the angle profile 1. The second parts 20 of these same four profiles extend on the side of the inner faces of the side walls of the residence / house, that is to say on the side of the 90° corner junction.
[0059] With reference to figures 1 and 2, the angle profile 1 is designed to allow two posts 13, 13', which are for example posts with a substantially rectangular or square section, to be wrapped on three sides when the latter are placed against the central web 30 of the angle profile 1.
[0060] With reference to figure 1, the profile 1 not only forms a pair of long cavities C1, C2 adapted to accommodate the posts 13, 13' against the central web 30, but also delimits one or two additional cavities C3, C4, each delimited in part by a face F31 or F32 formed at an axial end of the central web 30 and which extends, for example, in a substantially planar manner, here perpendicular to the longitudinal axis Z1.
[0061] Regardless of the precise geometry chosen to delimit the respective cavities C1, C2, C3, C4, the profile 1 allows for the retention of structural components 11, 11', 12, 12', 13, 13' against the first L-shaped section 10, thanks to the second section 20, which is shaped like a rod with two perpendicular faces oriented towards the first section 10. The connection of this second section 20 to the first section 10 is further facilitated by a central web 30, preferably solid and made of the same material as the first and second sections. An optimized thermal insulation effect can thus be achieved in the corner area by selecting a material M with low thermal conductivity, each concrete component being sandwiched between two layers of the material M constituting the corner profile 1.
[0062] Referring to Figure 2, the profile 1 forms a multi-cavity arrangement along the first section 10 and adjacent to the central web 30, facilitating the installation of rigid structural components, such as beams 11, 11', 12, 12' and columns 13, 13', arranged in three directions at 90° angles to each other. In particular, the end cavity(ies) C3, C4 allow for the sandwiching of beams, here a lower beam 11' and a top beam 12', which can be inserted from the same side as a column 13, 13' housed in an elongated cavity C2 and shorter / lower in height than the profile 1 in its assembled state.
[0063] In this non-limiting example, the angle profile 1 has two end cavities C3, C4 having the same dimension along the direction of the longitudinal axis Z1, allowing the respective ends of the two beams 11,' 12' of respective heights h1 and h2 to be fixed together, with the following relationship satisfied: h1 = h2. In addition, the following relationship can be satisfied: h2 + h3 = H where H represents the height of the angle profile 1, and h3 represents the largest dimension of the column 13', possibly supplemented by a thickness of product / layer for joining by chemical keying. In the assembled state of profile 1, the 13' post can be joined / connected from above to the bottom beam 11' inserted into the bottom end cavity C3 and from below to the top beam 12' inserted into the top end cavity C4. panel assembly function
[0064] The angle profile 1 has, on both sides 2, 3, including the free edges of the first L-shaped section 10, interconnection means for connecting to construction panels 41, 42. In one embodiment, these interconnection means 6a, 6b, 7a, 7b are provided not only on edges of the first section 10 but also on edges of the second section 20. Preferably, the profile 1 includes a tongue-and-groove system to ensure parallelism between the panels 41, 42. fit together (which have a plate format) and the connecting side 2 or 3 formed by the angle profile 1.
[0065] As clearly shown in Figure 2, profile 1 has a pair of female elements 6a, 7a with an elongated groove along the direction of the longitudinal axis Z1 or a similar female part. These female elements are distributed on each of the two sides 2, 3, for example, forming: - a first female organ 6a, for example with a groove, on the edge of a flat portion of the first part 10 (here arranged on the second side 3) and on the edge; - a second female organ 7a, for example grooved, in the second part (20) and on the side 2 which is turned at 90° with respect to the first female organ (so here, on the first side 2).
[0066] Similarly, the angle profile 1 may have a pair of male organs 6b, 7b, optionally each designed as an elongated tongue L3, L3' along the direction of the longitudinal axis Z1. These male organs may be distributed on each of the two sides 2, 3, in a manner complementary to the female organs, for example by forming: - a first male organ 6b, projecting on the edge of a flat portion of the first part 10 (projecting outwards / in the opposite direction to the central core 30), this first male organ being designed and arranged to fit into a female organ provided in one of the construction panels 41, 42 and substantially of the same size and geometry as one of the female organs 6a (with geometry with two spaced tongues L1, L2) provided in the profile 1; - a second male organ 7b, formed in the second part 20 and extending outwards on the second side 3 in the opposite direction to the central core 30, this first male organ 7b being designed (for example as a tongue) and arranged to fit into a female organ provided in one of the construction panels 41, 42 and substantially of the same size and geometry as one of the female organs 7a (with tongues spaced L1', L2') provided in the profile 1.
[0067] Optionally, the extension direction of the tabs of the 6b, 7b components is arranged at 90° between any tab or male component 7b on the second side 3 (in the X direction for the second side 3) and any tab or male component 6b on the first side 2 (in the Y direction for the first side 2). More generally, the interconnecting means can form raised sections which, in the first section 10, extend away from the junction between the two flat portions of the first section 10, and in the second section, extend away from the central core parallel to the raised sections on the same side 2, 3 located on a free edge of the first section 10.
[0068] Four connection regions to construction panels 41, 42 have been described here, the four regions being: - provided with tongues or interlocking reliefs which form extensions (typically thinner / narrower) relative to the respective sections of the first part 10 and the second part 20, continuously along the entire length of the profile 1; and - distributed in pairs on each of the two sides 2, 3 of the angle profile 1, on either side of a corresponding cavity among the elongated cavities C1, C2. In alternative embodiments, the interconnection means provided in the first part 10 and / or in the second part 20 may be recessed and / or arranged discontinuously, possibly without any thinning effect relative to the rest of the corresponding section 10 or 20. Recesses for receiving bosses provided in panels 41, 42 may be included in alternative embodiments.
[0069] When two end cavities C3, C4 are provided, the arrangement of the interconnection means is adapted to allow the finalization of the installation of panels 41, 42, generally parallelepiped in shape, slid and / or sandwiched vertically along the lower beams 11 or 11', before the installation of the beams 12, 12'. Thus, the four beams 11, 11', 12, 12' are positioned at the same height as the end cavities C3 and C4. This type of positioning can be achieved with a horizontal guiding effect on the panel 41 or 42, by at least one of the beams already in place.
[0070] In the non-limiting example of Figure 2, the interconnecting means are selectively distributed on both sides 2, 3, being arranged outside the respective cavities C1, C2, C3, C4 of the profile 1. Thus, there is no interference between the reliefs required for the interconnection and the placement of the rigid structural components, which can be prefabricated and concrete-based. Example of angle profile design
[0071] The angle profile 1 can be further notched or perforated at its axial ends E1, E2, due to the shorter dimension of the central web 30 compared to the other parts 10, 20. A material extraction step M can be carried out to obtain two end cavities C3 and C4, which are respectively L-shaped (in a cross-sectional view / perpendicular to the axis Z1). These cavities thus open onto each of the sides 2 and 3 for the connection of construction panels, which may also include a layer of insulation, possibly made of the same material as the profile 1. The material extraction M carried out to obtain the cavities C3, C4 can use the same tool or equipment as that used to obtain the cavities C1, C2, and / or the material extraction can be carried out simultaneously to obtain all or parts of the elongated cavities C1, C2 and at least one end cavity C3, C4.
[0072] With reference to Figures 1 to 3, we can see that an L-shaped end cavity C3, C4 can exhibit: - on each of the two sides 2, 3 of the profile 1, the same width L5 of lateral opening, measured perpendicularly to the longitudinal axis, , - a height h (measured parallel to the longitudinal axis Z1), for example greater than 140 mm, which may be close to or identical to the width h5. In the implementation options, the width L5 and / or the height h are between 140 and 300 mm, preferably between 150 and 210 mm. Furthermore, the h:H ratio can optionally be between 1:20 and 1:5.
[0073] The prefabricated angle profile 1 can have a height H of 2 or 2.3 meters or more to ensure sufficient ceiling height in the residential structure. The maximum length is, for example, approximately 3 meters. A length of approximately 2.5 or 2.6 meters may be preferred. During block production, it is permissible to produce a longer elongated block (for example, 5 or 10 meters long), which can then be cut into several pieces (into two or four pieces if the desired length / height H is 2.5 meters) to obtain two rough blocks of suitable length before cutting / removing material, at least to create the end cavities C3 and C4.
[0074] The elongated cavities C1, C2 can each be delimited by a pair of faces that are parallel to each other and distributed in the first part 10 and in the second part 20, having a depth greater than or equal to 90 mm, for example a depth less than width L5 and / or less than height h, this depth not taking into account the reliefs or similar parts forming the interconnection means 6a, 6b, 7a, 7b. In some options, the sum of the depth of the cavities C1, C2, adding / taking into account the tabs constituting the interconnection means 6a, 6b, 7a, 7b, can be substantially equal to the width L5 and the height h, so as to have a delimitation (in cross-section) of the cavity C1 or C2 in the form of three sides of a square section.
[0075] As illustrated in Figure 3, each end cavity C3, C4 can be decomposed into three sub-volumes V0, V1 and V2, which have, for example, a similar, possibly identical, rectangular or square cross-section, with: - the sub-volume V0 which corresponds selectively to the part of the cavity delimited by the face corresponding F31 or F32 of the central core 30, so that this sub-volume does not axially extend any of the cavities C1, C2; - the sub-volume V1, directly adjacent to the sub-volume V0 and extending an elongated cavity C1, forming the opening of the end cavity, on the first side 2 of the profile 1; and - the sub-volume V2, directly adjacent to the sub-volume V0 and which extends the other elongated cavity C2, forming the outlet of the end cavity, on the second side 3 of the profile 1.
[0076] The central core 30 optionally defines, through cutting and / or milling (or shaping during molding), two areas (by its opposing axial faces F31, F32), each of which is greater than the area axially defined by the second part 20 and less than the area axially defined by each face F1, F2 of the first L-shaped part 10. In the first part 10, a first thickness e10 is provided for each of the two portions extending at 90° to each other from their longitudinal junction J (where a corner edge or re-entrant angle of the profile is formed). This thickness e10 can be greater than or equal to 80 mm, preferably between 90 and 120 mm, which ensures good strength.This ensures robustness in the wrapping of the 13 and 13' posts and also the wrapping of beams as described in detail later, by a single angle profile 1 which is less dense than the beams and posts 11, 11', 12, 12', 13, 13'.
[0077] The central core 30 can be comparatively thicker, in one or two directions (X, Y), than the thickness e10 of the first part. The maximum thickness of the central core 30 is, for example, between 140 and 320 mm.
[0078] Corner profile 1 can be made of a lighter material than concrete or other materials used in structural frame columns. For example, the material of corner profile 1 essentially contains a thermally insulating polymer or cellular plastic material M, such as EPS (expanded polystyrene) or a rigid material containing polyurethane. More generally, corner profile 1 can be made from a non-mineral material or a composite structure produced as a single unit, combining the advantages of lightness, strength, and thermal insulation properties. As an example, the cellular plastic material M essentially consists of expanded polystyrene with a density between 16 and 25 kg / m³. 3 , for example approximately 20 kg / m 3 .
[0079] In some embodiments, the angle profile 1 is produced in one piece, typically as a single unit resulting from hot molding and obtained after at least one cutting or similar operation to remove material, in order to form the cavities C1, C2, C3, C4 of the profile 1. By way of non-limiting example, it may be possible to successively: cut a block of polystyrene and then perform milling. Among the production options for the molded building block constituting the angle profile 1, the choice is made between making a cut followed by milling operation(s) or a succession of cuts.
[0080] The junction regions of the central web 30 with the first part 10 and with the second part 20 can be identical along the entire length of the central web 30. The cross-section of this central web 30 can lie entirely within the limits of the cross-section of the angle profile 1, with a distance of at least 100 mm from the smallest square inscribed within these limits. Optionally, the angle profile is devoid of a part projecting on the side of the re-entrant angle formed by the first part 10, that is to say opposite the first side 2 and opposite the second side 3, the external faces of the first part 10 being able to be substantially flat.
[0081] With reference to figure 3, it can be foreseen that the section of the angle profile 1 is inscribed in a (virtual) square 80 whose width d1 coincides with two dimensions of the outer part 10, which has a cross-section in L.
[0082] Although a one-piece construction is preferred, profile 1 can also result from an assembly step between at least two complementary sub-blocks, assembled and fitted / adjusted against each other. After the assembly step of profile 1, there is no relative mobility of one of the sub-blocks with respect to the other within profile 1, particularly after placing two posts 13, 13' on either side of the central web 30, filling the cavities C1 and C2. Use of corner profiles and panel assembly methods
[0083] A method for assembling a set with at least four corners using a corresponding angle profile can be implemented, for example by first mounting two posts 13, 13' (of identical length or with one possibly being shorter) vertically against the central web 30 of the first angle profile 1 and mounting a pair of beams 11', 12' (top and bottom) inserted into the end cavities 3, 4 on either side of the post 13, 13', which allows the assembly of construction panels to begin on one of the two sides of the first angle profile 1. The direction arrow X1 in Figure 2 illustrates a possible starting point for interlocking construction panels.
[0084] A seal can be provided for the installation of the posts 13, 13'. They can each include a steel stud (for example a Trimex® stud) at their base, inserted axially into a suitable hole, for example already provided in the slab D. On the upper side of the post 13, 13', axially projecting ends A, for example made of steel, can be formed to occupy a sub-volume of the end cavity C4, for example as close as possible to the face F32.
[0085] In some options, all or part of the upper beams 12, 12' can rest / seat on part of the face F32 and / or on the corresponding column 13, 13', extending into the end cavity C4. In some options, this involves a partial insertion of the prefabricated beams and a keying is carried out with a mortar 15 (keying mortar, for example of the Clavexpress® brand type 700 or equivalent) which encases the protruding ends of reinforcement A and finishes filling the end cavity C3 above the face F32, as illustrated in figure 2 (ends A appearing in dashed lines in the joint resulting from the keying).
[0086] An optionally different arrangement can be provided in the lower part, within the end cavity C3. Optionally, at least one of the lower beams 11, 11' acts as a stop integral with the slab D. The stop can be made of concrete / reinforced concrete. It can be, for example, in the form of an (elongated) butt plate made of rigid material, possibly plastic. Mechanically fixing a prefabricated butt plate to form a lower beam can, optionally, allow for an increase in the polystyrene thickness. This butt plate, joined to a column 13, 13', can primarily serve a positioning and alignment function for the construction panels 41, 42, without any structural role. The columns 13 and 13' can be made of reinforced or fiber-reinforced concrete, for example, ultra-high-performance fiber-reinforced concrete. Part of the beams, for example the upper beams 12, 12', can also be made of fiber-reinforced concrete.
[0087] Next, the installation of a corner profile (the second profile to begin with) is repeated, along with two posts, one of which is located on the same side as the first corner profile 1: this creates the first wall section. The beams 11', 12' of this section are connected to the corresponding post attached to the central web 30 of the second corner profile. The assembly can continue with assembled panels (for example, along the Y1 direction, but on the side of the second corner profile), after installing the bottom beams and posts with the appropriate orientations between the second and third corner profiles. The top beam(s) are mounted horizontally to support the panels, resting on the post(s) already installed for this new wall section.Finally, the last two sections of wall can be completed, first by installing the panels in the opposite direction to X1, towards the third corner profile, and then by installing the last of the four corner profiles. The top beams are added to finish.
[0088] The panels 41 could be mounted against the first angle profile 1 in order to bend them between two beams 11, 12 and two posts, including post 13 illustrated in figure 2. The junctions in the end cavities C4 can be made at this stage, to obtain the structural post-top beam and top beam-top beam junctions.
[0089] This is a basic example for a simple four-sided wall construction, such as the one shown in Figure 4A. Referring to Figures 1 and 2, the principle of attaching and bending the construction panel 41 (here in the form of a modular panel, prefabricated with an insulating layer across most of its thickness) against the faces F11 and F12 of the beams 11 and 12, and against the face F13 of a column 13 already attached to a central web 30 of an angle profile 1, with this column 13 enveloped by the components of this angle profile 1, ensures efficient assembly. The three-directional extension geometry of the connected structural elements, made possible by each angle profile 1, allows for easy right-angle assembly of the panels 41 and 42, while maintaining continuous insulation at the corners.
[0090] The smaller width d20 (compared to the width d10) of the second part 20, shaped essentially like a straight rod, possibly provided with interlocking reliefs, allows the two parts 10 and 20 to form two connecting faces perpendicular to each other and parallel to the longitudinal axis Z1. This can optionally allow for panels 41, 42 that have two correct interconnection positions, with two interchangeable vertical faces or edges (parallel to the axis Z1 in the assembled state).
[0091] The interlocking or similar interconnection of panels 41, 42 can be achieved without special tools, in the absence of separate locks (nor is there any screwing of additional elements). The combination of parts 10 and 20, delimiting the inner faces of the cavities C1, C2, C3, C4 and carrying the reliefs / interconnecting elements, allows for simple assembly of panels on both sides 2, 3 of the corner profile 1.
[0092] The angle profile 1 can be easily positioned between two lower beams 11, 11', located on the two sides 2, 3 of the angle profile 1, without hindering the installation of the column 13 or 13'. Thus, these components are mounted perpendicular to each other, with at least one of the lower beams 11, 11' aligned and / or engaged horizontally in the first end cavity C3 of the angle profile 1. The two other beams 12, 12', installed subsequently, can also be distributed on the two sides 2, 3, mounted perpendicular to each other. At least one of the upper beams 12, 12' is engaged and / or aligned horizontally in the second end cavity C4, as clearly shown in the non-limiting example in Figure 2.
[0093] The respective ends E3, E3' of the posts 13, 13' can be joined to the beams 11, 11', 12, 12', with at least one upper joint made inside a corresponding end cavity C4. With this arrangement of cavities C1, C2, C3, C4 in a rigid angle profile 1, the construction panels 41, 42 can be assembled on each of the two sides 2, 3 by being sandwiched respectively between two of the beams 11, 12 and 11', 12' which extend horizontally on the same side (2 or 3) at two height levels corresponding to the height levels of the end cavities C3, C4.
[0094] Referring now to Figures 4A and 4B, we can see that the walls of a residential structure 4 or 4' can be easily obtained by assembling prefabricated components, with just a few chemically bonded joints against the 13, 13' posts or similar joints, using angle profiles 1 in the corners of the dwelling. Here, four sides of the quadrangular residential structure 4, 4' are formed. A residential structure arrangement is obtained including one profile 1, for example as illustrated in Figures 1 and 2, and three other angle profiles to form the four corners of the residential structure.
[0095] The panels 41, 42 can have the same height as the profiles 1 in assembly options and they are joined to the slab D by fitting together, by the cooperation of the lower groove R with the lower beams 11, 11' which are adjacent to one of the posts 13, 13' and typically aligned, in each wall section, with the corresponding opening of the lower end cavities C3 of the corner profiles 1 provided at both ends of the wall section considered.
[0096] With reference to Figure 1, the profiles 1 can connect panels 41, 42 with a single circumferential groove (on the peripheral edge area) of the same depth, forming the horizontal grooves R (at the bottom, on the side of the lower end 40a of a panel) and R' (at the top, on the side of the upper end 40b of a panel), as well as the vertical grooves or channels CP delimited between two coupling edges 46, 47. These two coupling edges 46, 47, here vertical in the assembled state, are complementary to the interconnecting means 6a, 6b, 7a, 7b arranged vertically on each of the sides 2, 3 of the angle profile 1.
[0097] The cavities C1, C2, and the panel cavities formed by the CP grooves fit together to allow the complete lateral wrapping of a corresponding 13, 13' post, with continuous insulation. Continuous layer insulation is permitted, for example, between: - a first layer of panel 40c and the flat portion of the first part 10, which is of the same thickness as the first layer 40c; and - a second layer of 40d panel and the second part 20 which is the same thickness as the second 40d layer. Furthermore, the lower beams 11, 11' can be completely enveloped by the horizontal slab D, and the construction panels 41, 42 superimposed on these lower beams 11, 11' with an interlocking effect in the lower grooves R.
[0098] Between the two layers 40c, 40d, each construction panel 41, 42 may have an intermediate layer 40 with a thickness substantially identical to that of a post 13, 13'. A post may be provided at regular intervals, for example 1.5 meters in the wall of the residential structure 4, 4', the panels 41, 42 filling the spacing between the posts 13, 13' except at the corners, which include an angle profile. Indeed, at these corners, two consecutive posts are separated from each other only by the central web 30 of an angle profile 1.
[0099] All or part of the construction panels, which are preferably of the same height, have a maximum height equal to the height H of each of the corner profiles 1. During the assembly process of a side wall of the residential structure 4, 4', it is planned to make the connections of the lower beams 11, 11', respectively the connections of the upper beams 12, 12' so as to orient them at 90° to each other, on the two sides 2, 3 of the angle profile 1.
[0100] One advantage of angle profile 1 is its compatibility with direct assembly of prefabricated components, while meeting requirements for energy efficiency (thermally insulating character) and mechanical resistance / durability.
[0101] The invention is in no way limited to the embodiments described and illustrated, which have been given only by way of example. For example, the angle profile 1 may optionally have a rounding or a curvature on the outside of its first part 10, for example at the level of faces which do not participate in the wrapping of structural components denser (columns and beams) than the angle profile 1 (comparatively lighter / less dense). Also, profile 1 can include or be part of a block assembly allowing one or two additional sides to be defined in a variant for a particular need, with the possibility of defining one or two additional cavities accessible laterally.
