Description

SUPPORT STRUCTURE FOR ADDITIONAL CONSTRUCTIONS,

  ESPECIALLY OF THE GENRE VERANDAS OR THE LIKE

  The present invention relates to a support structure for ancillary constructions, in particular delimiting a space or a room adjoining a main construction, such as verandas, winter gardens, lean-to, canopies or the like, or even

curtain wall type.

  We already know in the building technique methods for erecting such light constructions in addition to an already existing construction for

  to increase the surface area and the amenity. In particular, from-

  then several years, we made similar structures

  tures by means of metal profiles, of light alloy

  ger, comprising means of mutual connection from one profile to another to constitute frames, posts, brackets or other assembly members, necessary for

  the cohesion of the structure. The plaintiff has in part

  particular developed in this field a wide range of products, compatible with each other, able to realize by

  appropriate links any form of pan-

  roofs or roofs according to the geometry of the structure, and

  which are necessary for the construction of this last-

niere.

  But, when for aesthetic reasons or more generally to better match the structure to be produced with the rest of the construction according to the style

  of the latter, we wish to use other materials

  than light alloy metal profiles, the

  conventional systems are generally not well suited

  your. Indeed, for example to cover a veranda with a tiled or slate roof in particular, it is essential that the supporting posts of the structure can support the corresponding load, which is usually not possible when these posts

  are made with simple profiles.

  In these circumstances, it is practically essential to have recourse to posts or more generally to more resistant structural elements, in particular of wood, these elements having a sufficient section to ensure the support of the

  charge, with possible interposition of a truth

  ble roof support structure. The assembly of these elements together then requires appropriate means such as pegs, tenons, recesses, mortises, etc., which most of the time require prior preparation in the workshop with additional adjustment of the

  elements on site, mounting and adapting the parts

  these thus prepared generally making inter-

  come the carpenter's technique and know-how

  pre to this one. Therefore, it is hardly possible to conceive an efficient and large-scale industrialization for this kind of realization, as it is the case.

  on the other hand with metal profiles which require

  are only trying to assemble a less specialized workforce, construction can be carried out in

  following precise assembly instructions

  both the simple bracing and fixing of these pro-

  spun in all desired configurations, such as

  that rafters, ridge, sand pits, sleepers ...

  The subject of the present invention is a structure

  support structure which overcomes this drawback

  so much to design and use structures too

  well in wood than in light alloy or other, while avoiding

  both the usual operations of final adjustment of the

  wooden ties which, on the contrary, are arranged to adapt directly to other elements, also made of wood or metal thanks to connecting members,

  the implementation does not require any rectification operation.

  particular tion. The wooden parts according to the invention and the possible metal profiles to be associated with these parts being previously supplied, the implementation of the invention requires only simple maneuvers for the assembly of these parts, suitable for being assembled and

  locked together in any orientation

  relative tion required by the configuration of the structure

re to achieve.

  To this end, the structure considered is characterized

  térise in that it comprises elements in the form of hollow beams, made up of wooden pieces joined and glued together to delimit a section of beam meeting precise tolerances while also exhibiting excellent dimensional stability, each beam internally comprising a part central hollowed out and in its external surface at least one longitudinal groove adapted in particular to receive the heel of a connecting member joining one element to another,

  together forming a predetermined angle.

  According to a particular characteristic of the invention, the connecting member comprises a heel capable of being mounted and then preferably fixed in the longitudinal groove of an element, this heel being extended by a perpendicular tab or making a given angle with the plane of the groove and on which is articulated or fixed at least one yoke, or the like, mounted in the hollowed-out central part of an element attached to that comprising the groove, this yoke, or the like, being crossed by an eccentric axis, such that the rotation of this axis exerts on the yoke a tensile force allowing, by mutual reaction, to apply the two

  elements closely against each other.

  Preferably, the adjoining wooden pieces are each made according to the known technique known as glulam, using thin wooden plates previously cut, stacked and glued from one to

the other in the stack.

  According to another characteristic, the yoke is articulated on the lug extending the heel around a transverse axis allowing any orientation

  predetermined screed and therefore the angle of adjustment

  one against the other of the two elements joined together

ble by the connecting member.

  According to yet another characteristic, the heel tab has one or more axes for as many yokes each receiving an element, these elements being

  attached to the one whose groove carries the heel.

  Advantageously, the eccentric axis crosses

  sant the yoke is extended in two facing bores provided in the wall of the element receiving this yoke and in which the axis swivels under the effect of a means of control in rotation of the kind hexagon wrench

hollow or others.

  According to yet another characteristic of the structure according to the invention, the longitudinal groove of each element is arranged to receive if necessary a metal profile mounted and immobilized in

  this groove, to receive a panel or glazing.

  Other characteristics of a support structure established in accordance with the invention will appear

  again through the following description of various examples

  ples of realization given as an indication and not li-

  mitative, with reference to the accompanying drawings in which: - Figure 1 is a perspective view of a

  In the embodiment illustrated on the

  Figure 1, reference 1 designates a veranda or cons-

  truction similar annex intended to be applied against a wall 2 of an already existing construction in order

  to increase the useful surface of the latter.

  The veranda 1 generally comprises a supporting structure 3 for a roof 4, the latter being able to be produced; in the example considered, at

  using tiles 5 but also comprising pan-

  glass windows 6 held in metal frames 7.

  Roof 4 is inclined horizontally and rests

  on a frame 8, itself supported by the structure

  re 3, this frame being associated with panels la-

  9 closing the openings, here triangular in shape

  area resulting from the inclination of the roof.

  The supporting structure 3 essentially consists of vertical beams 10 braced according to the configuration chosen for the sides of the veranda at

  by means of horizontal beams 11 of the same kind. Wash-

  randa has glass parts 12, an access door

  13, trim panels 14 and in the example

  flabbergasted, sliding glass openings 15, mounted inside metal frames 16. The door 13 can also be glazed and include a frame 16

  analogous, being sliding again or, as it-

  glossy in the example shown, hinged mounted

on the supporting structure.

  In accordance with the invention, the beams 10, respectively 11, used in the production of the support structure 3, where appropriate in the production of the frame 8 on which the roof 4 rests, are formed by means of an assembly of parts wooden suitably joined and glued together, as well as

  illustrates the partial sectional view of Figure 2.

  Each beam can thus be formed by the as-

  appropriate appearance of unitary parts such as 17a, 17b, .... 17th, each of these having a shape

  adapted exterior allowing their nesting or mounting

  relative age, in particular by tenons and mortises, in reali-

  an elongated rectilinear beam. In particular, the shape of the parts 17 is chosen so that the beam produced has a hollowed-out central part 18 and an external profile whose general square or rectangular shape, has in at least one of its faces an open longitudinal groove 19, proper to be received by interlocking, either a metal profile constituting one of the chassis 16 for example of a glazed part of the

  veranda, or, as described below, a piece of connecting

  its own to allow the mutual assembly of two pou-

  very hollow in wood in a relative orientation of

these predetermined beams.

  Advantageously and preferably for the implementation of the invention, although in itself

  non-exclusive, each of the unit pieces 17a, 17b ...

  17th, forming hollow beams 10 and 11 of the structure

  ture, is made according to the known technique known as glulam, where each of these pieces is made of thin wooden plates, previously cut

  to the external profile of each of these parts, these plates

  bowls then being stacked and glued together. These

  provisions allow in particular to carry out

  very long wooden ones, for example up to 6 m long, with perfect dimensional stability under ordinary conditions of use, while respecting precise dimensions - both for internal recess 18 of each beam and for the outer longitudinal groove or grooves 19, the tolerance possibly being of the order of plus or minus 1 mm. Figures 3 and 4 illustrate the installation

  between two beams 10 and it respectively perpendicular-

  links to each other of a connecting member 20 allows

  both to link the beams rigidly without requiring any particular adjustment, these beams being supplied from the workshop as is with the only obligation, when mounting the desired veranda, an adjustment of their length, which exclusively requires the use of a saw-like cutting tool or the like, without further operation. To this end, the connecting member 20 consists of a first part 21 comprising a heel 22, the

  transverse dimension corresponds substantially to the lar-

  geur of the longitudinal groove 19 of one of the beams to be assembled, for example the beam 10. Screws such

  that 23 allow the heel 22 to be immobilized in a po-

  determined position chosen according to the length of the groove

  re, in particular at the right of the assembly to be produced with a second beam 11. The heel 22 has for this purpose a central tab 24, extending perpendicular to the

  heel plane 22 and able to be secured by the inter-

  medial of a transverse axis 25 with a yoke 26, .la

  tab 24 and the yoke 26 thus articulated on this latter

  nière being engaged in the hollowed out part 18 corresponding

  dante of the beam 11 to be assembled with the beam 10 in

  the longitudinal groove 19 which was previously-

  ment immobilized the heel 22. The yoke 26 has two lateral arms 27 and 28 extending on either side of

  the tab 24, these arms extending by a hollow part

  29. Through it and bearing against its upper face, an eccentric pin 31 is arranged, the ends respectively 32 and 33 disposed on either side of the part 29 are engaged in bores of the same diameters provided in the opposite faces of the beam 11. The axis 31 moreover comprises at its end 33 a hollow imprint 34 suitable for receiving the end of a control tool of the six-wrench type

  hollow sides, for example, to ensure rotation

  tion of the axis and, following this, a tensile force on the yoke 26. The reaction which

  results on beam 11 relative to beam 10 per-

  puts in these conditions to immobilize in position these two elements by ensuring their mutual locking in position. In the example illustrated in Figures 3 and 4, the beams 10 and 11 extend perpendicular to each other. Variants can be provided

  as shown for example in Figures 5 and 6 per-

  putting to assemble respectively two, then three for

  very 10 to the same beam 11 or vice versa.

  In the example illustrated in Figure 5, the

  connecting gane again comprises a tab 24 provided with

  its opposite end of two respective parallel axes

  clothes 25a and 25b allowing to articulate on this leg

  24 of parts 35 and 36 each associated with an axis with ex-

  centric 37 and 38 performing in the same way as de-

  previously reviewed the immobilization of the beams 10 on the beam 11. The mounting is nevertheless provided so that the respective beams have notches 39 and 40 to ensure their respective nesting at the desired angles, one of the beams 10 being here perpendicular to beam 11 while the other

  makes an angle of about 45 'with the latter.

  In the variant illustrated in Figure 6, the beam 11 shown is associated with three beams 10 by a connecting member comprising a lug 41 with three axes of articulation respectively 42, 43 and 44 for three parts 45, 46 and 47, they -same associated with three eccentric axes 48, 49 and 50 ensuring as before the relative immobilization of the beams with

  suitable and predetermined mutual guidance

born.

  Figure 7 finally illustrates a detail of the realization of the veranda representing the assembly in beams such as 10 and 11 assembled together

  as previously described with a metal profile-

  lique 16, the latter being arranged to receive in appropriate grooves glass panels such as 52 and 53 with mounting if necessary inside the profile

of seals 54.

  We thus realize a new concept of cons-

  veranda or other annex type truction, using

  both elements in the form of wooden beams tu-

  binoculars, advantageously formed with uniform elements

  glued laminated shutters, as metal accessories, in particular in light alloy profile, these beams and profiles can be easily assembled together

  whatever their relative orientation.

  The construction thus obtained presents the advantage

  tage of being able to integrate perfectly with the style of the main construction to which it adapts, in

  additionally providing mechanical strength of the struc-

  largely improved tures allowing roof support

  tures or other significantly greater loads than in the conventional case where said veranda is formed only by means of metal profiles. Of course, it goes without saying that the invention does not

  not limited to more special examples of realization-

  ment described and represented above; she embraces it

on the contrary all the variants.

  In particular, the articulated yoke 26 can be removed and replaced by a part fixed directly or linked in another way to the lug of the connecting member and on which the eccentric axis carries by exerting on this lug the necessary force. to the

  joining of the two beams 10 and 11.
