Description

Method and device for corner assembly for making walls of

facade

  made of wood, with thermal insulation.

  The present invention relates to a method and a corner assembly device for the production of facade walls or exterior wooden walls, comprising thermal insulation. It also targets buildings such as chalets or others, making

  application of this method and this device.

  Various methods have been proposed to date, for making walls of

  wooden facade or exterior walls, provided with thermal insulation.

  According to document US Pat. No. 4,330,973, logs are split axially over the majority of their length, close to their ends, and a core of insulating material is interposed between the pseudo log halves obtained. The composite parts thus produced are superimposed horizontally and nested by grooving. The corner connection of these composite parts is obtained by half-wood notch, at the junction of their unsplit ends, and their remaining part, so that said ends visible from the outside of the constructed building contribute to give the appearance of a construction

  made using solid wood logs assembled by jointing.

  However, such composite parts are difficult to produce and can only be manufactured in the factory, so that their use poses supply and storage problems for builders of chalets or other wooden buildings. In addition, the continuity solutions existing in the insulating vertical layer formed by a plurality of more or less contiguous superimposed strips, leads to the formation of thermal bridges greatly reducing

the effectiveness of the insulation.

  Document WO-99/53153 describes a corner assembly device intended for joining perpendicular walls consisting of an outer wall formed of superimposed elongated pieces of wood, of an interior wall also made of superimposed elongated pieces of wood , and a thermal insulator

  housed in a space formed between said walls.

  The ends of the pieces of wood constituting the external and internal walls of two perpendicular walls are assembled by means of separate corner elements, stacked on one another and provided with notches cooperating with complementary notches presented by said ends. These corner elements comprise, on the one hand, a part projecting outside the construction and having the appearance of a log or a plank of solid wood, and, on the other hand, a part of smaller section provided with notches making it possible to establish a rigid connection between the external pieces of wood and the

interior wood pieces.

  This angle assembly device has the following disadvantages in particular: - a reduced level of solidity due to the fact that the forces to which the angles of the construction carried out are subjected, are essentially supported by the reduced section portion of the angle elements which assembles the pieces of wood making up the walls; - a limitation of its application to a single type of wall, due to the need to use specific planks for the production of the interior walls and, above all, the exterior walls of the insulated walls; - a relatively complex conformation of the ends of the planks intended for the assembly of the interior walls and the exterior walls of the walls, as well as of the parts of the corner elements intended to overlap

in said ends.

  The subject of the invention is a corner assembly device making it possible to remedy the above drawbacks, in the application to the construction of chalets or other buildings comprising facade walls or exterior walls of the kind comprising exterior walls and interior made of horizontal solid wood pieces assembled by guttering and between which is

housed thermal insulation.

  According to the invention, this object is achieved thanks to a remarkable angle assembly device by a combination of characteristics according to which the -3 end parts of the pieces of solid wood intended to constitute the external wall of two perpendicular walls are provided, at a distance from their end face, with notches allowing their cross assembly by mutual interlocking, so that said end parts can protrude outside the constructed construction, corner reinforcing elements comprising an outer part of section or profile complementary to the section of the pieces of solid wood constituting the outer wall, being joined to said projecting outer ends and fixed to the perpendicular beams constituting said outer walls, by means of a wooden cross-member, in order to seen from the outside, give the appearance of a log or integral solid wood beam of strong section, the external parts of these corner reinforcement elements being shaped so as to allow them to be stacked and assembled by means of swaging, said corner reinforcement elements further comprising, for example, an insertion part by means of which they are embedded in notches made in the upper and lower sides of the beams

exterior woods.

  According to another characteristic arrangement, the solid wood beams constituting the interior walls of the walls are also assembled in a cross fashion by mutual interlocking, so that their end part protrude towards the outside and that their end face be wedged

  against the internal face of the elements of the external wall.

  This corner assembly device provides several advantages: - it is simple and can be easily implemented without the use of a fixing device (screws, nails, staples, glue, etc.) or support system (frame, joists, etc.); - its various components can be manufactured in the workshop using automatic woodworking machines on the market; these components can be easily stored and transported; - the possibility of manufacturing on an automatic machine allows a variation of the profiles, thicknesses and species of wood, as well as thicknesses of insulation, according to the wishes of the customers; -4 - it allows the construction of chalets or other very stable and solid solid wood buildings, with thermal insulation hidden between two walls made of solid wood, and external projecting parts having the appearance of logs or beams of large cross-section jointed between them ; - it does not disturb the settlement of this type of construction; - it is fully compatible with the new French thermal regulations for residential buildings which set a minimum loss of walls of U = 0.47W / M2.K; - it allows the construction of exterior walls or facade walls without insulation, using only solid wood pieces prepared for

  mount the exterior walls or interior walls.

  The above goals, features and benefits, and more,

  will emerge more clearly from the description which follows and from the attached drawings in

  Reference is made to said drawings to describe an interesting example, although in no way limitative, of implementation of the method and production of the device.

according to the invention.

  It is emphasized that words such as "upper", "lower", "outer",

  "interior", etc., are used in the following description and in the claims,

  compared with the position occupied by the various elements constituting the device of the invention, when building a wall, these terms cannot

  therefore have any limiting nature.

  The implementation of the method and the device of the invention requires the use of six separate parts shown in FIGS. 1 to 12, namely: - an external element 1 consisting of a piece of elongated solid wood or plank, used for mounting the exterior wall of the walls; 6 - an external element 1A constituted by a piece of elongated solid wood or plank used to constitute the starting row of one of the external walls of each pair of walls assembled at 90, this element having a height corresponding to half the element 1 height; - an interior element 2 consisting of a piece of elongated solid wood or plank, used to draw up the interior wall of the walls; - an interior element 2A constituted by an elongated piece of solid wood or plank used to constitute the starting row of one of the interior walls of each pair of walls assembled at 900, this interior element having a height corresponding to half the element 2 height; - a first corner reinforcement element 3; - a second corner reinforcement element 3A having a height

  corresponding to half of the corner element 3.

  Element 1, an end section of which is shown in FIGS. 1 and 2, consists of a solid wood beam which may have a rectangular section or a semi-circular or approximately semi-circular section. One of its lateral faces or vertical faces (internal face) is planar, while its opposite lateral face (external face) can also be planar or curved, the beam in this case having the appearance of an axially split log. The opposite edges of these pieces of wood are provided with tongue (s) 4 and groove (s) 5 in counter-profile to allow their superposition

and their assembly by jointing.

  The end portions of the elements 1 have, at a distance from their end face, transverse notches 6 and 7 formed in their upper and lower sides, respectively, extending over the entire width of said elements. These notches 6 and 7 advantageously have a depth

  corresponding to 1 of the height of the elements 1.

  -7 In this way, the ends of the external elements 1 are connected to the remaining part of the beam, by a connecting part 1b delimited by the notches 6 and 7 and whose height corresponds substantially to the height Y2

of said elements.

  It is understood that the notches 6 and 7 allow a cross assembly of the end portions of the elements 1, so that the latter form a right angle after the said elements have been put in place and that their ends are projecting outside the outer walls. Pl assembled orthogonally

(Figures 13 and 17).

  Each inner wall element 2 or lining wall P2, one end section of which is shown in FIGS. 3 and 4, is also constituted by a solid wood beam of length less than that of the elements 1 so

  to be able to fit into the area delimited by the assembled external elements 1.

  Preferably, the elements 2 have a rectangular section, so as to comprise two large lateral faces, the large internal face 2 'visible inside the construction can have a curved profile giving the appearance of a log of solid wood. . The opposite edges of these pieces of solid wood are provided with tongue (s) 8 and groove (s) 9 allowing them to be assembled by

overlapping and bouvillage.

  The end portions of the interior elements 2 also comprise, at a distance from their end face, transverse notches 10 and 11 executed in their upper and lower sides, respectively, extending over their entire width. These notches 10 and 11 preferably have a depth

  corresponding to 1 of the height of the elements 2.

  Thus, the ends 2a of the interior elements 2 are connected to the remaining part of the beam, by a connecting part 2b delimited by the notches 10 and 1 1 and whose height corresponds substantially to the Y / 2 height

of said elements.

  It is understood that the notches 10 and 11 allow a cross assembly of the extreme portions of the elements 2, so that the latter form a right angle after installation and that their ends 2a are projecting at

  the outside of the lining walls P2 assembled orthogonally (FIG. 13).

  The lining elements 2 advantageously have a length such that, after mounting inside the area delimited by the external elements 1, assembled, they are in support, via their end face

  2c, against the internal face ld of said external elements.

  In this way, the lining structure formed by all of the interior walls of the facade walls is enclosed in all of the exterior walls of said walls. The projecting ends 2a of the elements 2 make it possible to provide a regular space 12 between the outer walls' and the inner walls, for housing a core of insulating material 13 such as glass or rock wool, etc., as well as for the passage of the different sheaths

  techniques (distribution, ventilation, packaging ducts, etc.).

  The thermal insulation is thus hidden between two walls P1 and P2, i5 behind the inner wall P2 which can have a solid log appearance similar to that of the outer wall PI. Drilled holes can be made in the interior beams 2 of solid wood, for the passage of electric wires

or other ducts or pipes.

  The external elements 1 and the lining elements 2 can have a thickness equal or not; the external elements 1 can be thicker than

  the doubling elements 2, or vice versa.

  The starting element 1A used at the base of one of the walls of each pair of external walls of walls PI assembled orthogonally, corresponds to the upper half of a normal external element 1 as it would be obtained, for example , by splitting said element in the middle. Its upper side is shaped to be able to be assembled by bouvillage to an external element 1 superimposed, and it has a notch 6 'to allow its cross assembly with another element 1 arranged perpendicularly. After this junction, its end 1a 'protrudes outside the assembly angle and it is then covered by an external element 1 of

normal height.

  The starting element 2A used at the base of one of the walls of each pair of interior walls of walls P2 assembled orthogonally, also corresponds to the upper half of a normal interior element 2, as it would result, for example , of the cut in the middle of such an element. Its upper side is shaped to be able to be assembled by bouvillage to an element 2 superimposed, and it is provided with a notch 10 'to allow its cross assembly with another element 2 arranged perpendicularly. After installation, its end 2a ′ is projecting outside the assembly angle, said starting element 2A then being covered by an internal element 2 of

io normal height.

  The reinforcing elements 3 consist of short pieces of solid wood. They comprise an external part 3a intended to be attached to the projecting end part 1a of the external beams 1 and a part allowing it to be fixed by means of a wooden cross-member on the external beams 1, arranged perpendicular to the previous ones, this fixing part comprising, according to the example illustrated, an inner part 3c of reduced height, connected by a connecting part 3b. Depending on the type of wooden beam selected, the shape and length of the fixing part 3b-3c may vary, as well as the type of notch made in the sections

  end of the external beams 1.

  According to the illustrated embodiment, the transverse notches 6 and 7 formed in the upper and lower sides, respectively, of the external beams 1, have a width corresponding to the sum of the widths of the connecting parts Ilb, 3b, of the said external beams and corner reinforcement elements 3, so as to allow the embedding of said parts in

said cuts.

  The notches 6 and 7 can be divided into two adjacent notches by a central partition 15a, 15b favoring the positioning of the beams

  exterior 1 and corner reinforcement elements, when mounting the walls.

  The external part 3a of the reinforcing elements 3 has a profile matching the profile of the external elements 1 and a length identical to the length of the visible end parts 1a of said elements. The opposite edges of the external parts 3a are shaped to allow the superposition and

  the jointing by jointing of said parts.

  The connecting part 3b has a width allowing it to be embedded in the notches 6 and 7 of the external elements 1, these notches being dimensioned to receive, at the same time, said connecting parts 3b

  and the connecting parts 1b of said external elements, as indicated above.

  There is shown in Figures 11 and 12, a starting reinforcement element 3A.

  These elements also consist of short pieces of solid wood having an outer part 3a 'and an inner part 3c' of height more

  reduced, connected by a connecting part 3b '.

  These starting reinforcement elements 3A correspond to the upper half

a normal reinforcement element 3.

  The outer part 3a ′ has a profile which is complementary to the profile of the outer end la ′ of the starting elements 1A to which it is intended to be attached. Its upper side is shaped to be able to be

  assembled by jointing to a superimposed reinforcing element 3.

  The reinforcing elements 3, 3A could be "grafted" otherwise on the external elements 1 or 1A, for example by means of a tail assembly

  dovetail, or any other crooked wooden assembly.

  It is understood that when the projecting outer ends la 'and 3a' of the starting elements 1A and 3A or la and 3a of the other elements 1 and 3, respectively, are joined, they together have the appearance of logs or wooden beams solid section of large cross-sectioned between them, so that the walls of the building which are seen from the front can be thinner,

  thus allowing more economical construction of buildings.

  The mounting of the reinforcing elements 3 on the external beams 1, by means of a simple cross-timber assembly, makes it possible to obtain a solid position of said elements, without the use of members (screws, nails,

  staples, ..;) or assembly products (glues).

  Attachment parts 1b, 2b and 3b or 1b, 2b 'and 3b' of the external elements 1, 1A, lining elements 2, 2A, and reinforcing elements 3, 3A, intended to be straddled by the elements 1 or 3, may include, laterally, vertical grooves 14 contributing to good guidance and to a

  perfect positioning of the straddle faces when mounting the walls.

  It is specified that the method and the device of the invention is also applicable to the construction of chalets or other buildings whose walls made of solid wood have re-entrant angles or angles other than orthogonal. - 1 2
