Description

The present invention relates to a method of assisting

  mutual appearance of prefabricated panels, as well as an assembly profile usable for the implementation of this method,

and the assembly obtained.

  More specifically, it concerns the mutual assembly of prefabricated wood-frame panels of the type used in the building industry for the construction of pavilions or

small buildings.

  It is known that, traditionally, wood frame studs define lateral sides of edges of the panels, which are juxtaposed by these side faces and that mutually assembling mutually assembled amounts of wooden frame and juxtaposed; generally, this mutual assembly is

  after the panels have been mounted, according to a

  vertical structure, on a base such as foundations.

  Known mutual assembly techniques all rely on a plurality of localized joint splints, which are arranged in a plurality of zones along the edge of the panels.

to assemble.

  According to one of these known techniques, a plurality of access lights to the juxtaposed frame posts are hollowed out in the inner partition wall of each panel, which allows

  to fix as many link splints on these, by bolt-

  swim; the lights are then closed again.

  This known technique requires many operations, which makes its implementation a long one; it is also necessary to use stainless steel or galvanized hardware to prevent oxidation over time, due to

  condensations, and this technique is therefore costly.

  According to another known technique, the mutual assembly of the panels is carried out by means of tabs forming tenon, which is engaged in blind holes arranged for this purpose in different areas of the edge of the panels before juxtaposing them; we use for this purpose either wooden tongues, which one can possibly sticking inside the studs of framing

  made of wood, defining the edges thus juxtaposed, that is to say aluminum tongues

  nium, in which case they are assembled to the wooden frame studs

by pointing.

  The implementation of this technique also requires many assembly operations, which makes it long and expensive. In addition, these two known techniques have the common disadvantages of a great difficulty of disassembly without destruction, and even of a quasi impossibility in the second case, and a mutual solidarity too punctual panels, allowing differences in sometimes sensitive deformation

  outside very limited areas of mutual solidarity.

  The object of the present invention is to overcome these drawbacks of known techniques by proposing a simple and fast process of implementation, which makes it easy to dismantle, and which can ensure mutual solidarity.

  continuous panels over their whole height or

  on this totality, so that the continuity between the panels is ensured in their zone of solidarity

  whatever the deformations they may suffer.

  For this purpose, to assemble mutually two prefabricated panels each of which has a side edge edge,

  defined by a wooden frame amount of this panel and

  tible to be juxtaposed to the side face of a similar

  the other panel, the present invention provides a method of

  characterized in that it is arranged along each of said faces

  lateral sides, in the corresponding wooden frame upright

  a respective dovetail groove extending over at least most of the length of said face and opening at at least one of its ends in a side face of the corresponding panel adjacent to said side face of singing, said side edges are juxtaposed by placing the grooves face to face and making the ends coincide with each other.

  respective songs of these, and introduces longitudinal

  grooves, at least over most of their length, by said open ends thereof, at

  less an elastically compressible longitudinally transverse section

  salty, with an external cross-section

  of the inner cross-section of the assembly formed by the two grooves placed face to face, so as to ensure by means of a slight transverse compression of this profile in

  the grooves an assembly compatible with the dimensional variations

  of wood amounts over time.

  Thus are solved the aforementioned drawbacks of known techniques; the dovetail grooves can easily be fitted into the wooden frame studs when they are produced in the factory, using completely traditional woodworking machines, which limits the insertion of the profile or profiles the operations that it is necessary to carry out directly on the site; this insertion can be performed quickly, easily, for example mallet after

  that the panels have been erected on a bedrock, and one obtains

  Maintain mutual solidarity of the panels offering any guarantee of keeping time, firstly because of its continuous character on all or almost all the height of the panels, which standardizes the possible deformations of the latter in their zone d mutual assembly, and on the other hand

  makes the elastically compressible nature of the assembly profile

  This makes it possible to ensure an assembly that is both energetic and capable of allowing the dimensional variations of the wood of the uprights without risk of bursting of this wood; in addition, with simple arrangements of the profiles and / or grooves receiving them, we can ensure easy disassembly of the panels by extracting the profiles out of the grooves, in a movement of

  relative longitudinal sliding of the introductory movement

  tion. According to a particularly favorable embodiment of the method, a hollow tubular metal profile having an inner cross-section and an approximately haomothetic outer cross-section corresponding to two opposite-oriented dovetails is used as an assembly profile. this profile being provided over its entire length

  an open slot communicating to it a transverse compressibility

  dirty elastic; advantageously, the slot is arranged at the bottom of the dovetail, in a longitudinal plane forming a plane

of symmetry for the profile.

  The profile is for example made of aluminum.

  Such a profile ensures the resistance in time and the inherent assembly rigidity Saux metal assembly elements,

  while presenting the elastic compressibility

  reading his introduction into the grooves and making his use

  compatible with the assembly of wooden elements, the

  dimensional stability is uncertain.

  In addition, advantageously, such a profile can be used

  as a cable passage or the like once the assembly achieved.

  Other features and advantages of the invention

  will emerge from the description below, relating to an example

  non-limiting implementation, as well as the attached drawings

  which form an integral part of this description.

  Figures 1 to 3 illustrate, in perspective views,

  three stages of implementation of the method according to the invention.

  Figure 4 is a cross-sectional view of the

assembly profile used.

  FIG. 5 shows a view of the two frame posts assembled during this process, in the juxtaposed state but before the introduction of the assembly section, in cross-section.

  relative to the average direction of the grooves.

  In Figures 1 to 3, there are designated respectively 1 and 2 two prefabricated panels each having a frame

  in particular defined by a peripheral frame, respectively

  3 or 4, closed on either side by two walls of

  5 and 6 or 7 and 8 respectively, in any suitable material known to those skilled in the art, the volume thus delimited inside each panel being advantageously filled with a thermal insulation material such as 9 known to those skilled in the art.

  The wooden frames 3 and 4, formed from an assembly of

  tents and sleepers, define by a flat face, respectively

  10 or 11, of a respective amount, 12 or 13, one face -

  side edge of the corresponding panel, respectively 1 or 2.

  By these respective lateral edge faces 10, 11, ori-

  perpendicular to their average plane 20 or 21

  (see Figure 5), Panels 1 and 2 are intended to be juxtaposed

  taposés and assembled mutually in a position in which leuimplarsm "20 and 21 merge and in which the facing walls 5, 6, 7, 8, judiciously offset from the

  faces 10 and 11, ensure a recovery of the junction between those

  ci as it is known in itself of the honoree of the trade.

  In view of such a mutual assembly of the panels, each

  faces 10 and 11 is hollowed out over most and preferably

  the entire length of the corresponding amount, respectively 12 or 13, of a continuous dovetail groove identical, respectively 14 or 15, advantageously arranged symmetrically with respect to the mean plane 20 or 21 of the respective panel; at at least one of its ends, and preferably at its two ends as illustrated, the dovetail groove 14 or 15 opens into a side face of the corresponding panel adjacent to the face, respectively 10 or 11 , in which it is hollowed, which frees access to the two grooves 14 and 15, at least one of their ends then in coincidence, when the panels are juxtaposed by the faces and 11 and that the grooves 14 and 15 are then placed in

  look at each other as shown in Figures 2 and 5.

  It is then possible, in accordance with the invention, to

  simultaneously troducing in these two grooves, by sliding in the middle direction 17 of the peripherally closed channel which they then define, an assembly section 16 whose length is approximately equal to that of the grooves 14 and

  , or several assembly profiles 16 introduced successively

  and whose cumulative length is approximately the same

  equal to this length of the grooves 14 and 15.

  FIG. 4, which will be compared with FIG. 5, illustrates a cross-section of a profile 16 used preferably for

  the implementation of the method according to the invention.

  This profile 16 is metallic, advantageously made of aluminum, and tubular, hollow; in cross section, it has an inner periphery 18 and an outer periphery 19 which, in the example illustrated, are homothetic and define

  for the wall of the profile 16 a constant thickness e.

  The peripheries 18 and 19 are symmetrical with respect to the same plane 22 which, when the profile 16 is inserted into the grooves 14 and 15 while the faces 10 and 11 are contiguous and the planes 20 and 21 merge, merges with him -even with

these two plans.

  With a slight elastic transverse compression of the profile 16, which allows the presence, over its entire length of an open slot 23 connecting its peripheries 18 and 19 and advantageously arranged in the plane 22, the profile 16 is complementary by its outer periphery 19 of the inner periphery of the channel that the grooves 14 and 15 together define inside the uprights 12 and 13 juxtaposed by their faces

  10 and 11 in a position in which the planes 20 and 21 wedge

  CIDENT. With reference to FIG. 5, it can be seen that this inner transverse section has the general shape of a symmetrical diabolo with respect to the 20-and 21-plane, on the one hand,

  and with respect to the combined planes of the faces 10 and 11 on the other hand.

  Indeed, the channel defined by the grooves 14 and 15 is delimited by the longitudinal bottom 24 of the groove 15, plane and

  parallel to the face 11 of the mast 13, by the two longitudinal flanks

  25 and 26 of this groove, which are arranged symmetrically

  only one from the other relative to the plane 21 and connect at the same angle, less than 90, at the bottom 24 dug at the

  connecting edges with the flanks 25 and 26 of the remains,

  27 and 28, the interest of which will appear later, by

  longitudinal bottom 29 of the groove 14, plane and parallel to the face.

  10 of the amount 12 at a distance from this face equal to the distance between the bottom 24 of the groove 15 and the face 11 of the upright 13, and the two longitudinal flanks 30 and 31 of the groove 14, planes, symmetrical one the other relative to the plane 20 and connecting to the bottom 29 at the same angle as the flanks 25 and 26 relative to the bottom 24 and through a recess, respectively 32 or 33, dug in the bottom 29 ; the different

254090 O

  parts of the groove 14 are dimensioned identically to the like parts of the groove 15, so that the connecting edges of the flanks 25 and 26 of the groove 15 with the face 11 of the upright 13 coincide respectively at 34 and 35 with the connecting edges respective sides 30 and 31 of the groove 14 with the face 10 of the upright 12 when the faces 10

  and They are juxtaposed and the planes 20 and 21 coincide.

  The spacing between the respective bottoms 24 and 29 of the grooves 15 and 14 has been designated by a, this distance being equal to twice the depth of each groove, by b la

  width of each groove at the bottom, defined as the distance between

  perpendicular to the plane 20 or 21 the intersection of the flanks of a groove with the plane of the bottom thereof, and by the angle, less than 90, that forms any of the flanks

  groove with the bottom of the corresponding groove.

  Incidentally, the outer periphery 19 of the profile 16 is defined by a plurality of flat longitudinal faces intended to be applied under pressure, but with the possibility of sliding in the direction 17, against the faces 24, 25,

26, 29, 30, 31.

  Thus, the profile 16 has a flat longitudinal face

  36 oriented perpendicular to the plane 22, and disposed symmetrically

  only with respect thereto, which face 36 is aligned along parallel edges 37 and 38, arranged symmetrically with respect to the plane 22 at a relative distance c, measured perpendicularly to this plane, at two flat longitudinal faces

  39 and 40 located on the same side with respect to face 36 and

  to get closer to one another in the sense of

  relative to their connection to this face 36, in

  with this one the same acute angle f; along their inter-

  respective section, 41 or 42, with a longitudinal plane 53

  dicular to the plane 22 and coinciding with the plane coincident of the faces 10 and 11 when the profile 16 is engaged in the grooves

  14 and 15 juxtaposed, the faces 39 and 40 are respectively connected

  with respect to planar longitudinal faces 43 and 44, symmetrical to each other with respect to plane 22 and approximately symmetrical with face 39 and face 40, respectively, with respect to plane 53; along edges 45, 46 parallel, symmetrical to each other with respect to the plane 22 and approximately symmetrical respectively of the edge 37 and the edge 38 by

  plan 53, the faces 43 and 44 are respectively connected

  flat longitudinal faces 47 and 48, approximately coplanar and perpendicular to the plane 22 towards which they are directed from the respective edge 45 or 46; the faces 47

  and 48 stop at a distance from the plane 22, to connect

  respectively flank 49 and flank 50 of the slot 23, which flanks are planar, approximately parallel to the plane 22 relative to which they are arranged symmetrically to one another, and provide the connection between the outer periphery 19 and inner 18 section 16; the width of the slot 23, defined as the distance separating the flanks 49 and 50 perpendicular to the plane 22, has been designated by 1 the distance, measured parallel to the plane 22, and equally equally distributed on either side of the plane 53, separating the approximately coplanar faces 47 and 48 of the face 36, and f the distance separating

  the edges 45 and 46 perpendicular to the plane 22.

  The distances c and d coincide appreciably with the distances b and a, respectively, and the values of the angle et and the distance f coincide approximately with those of the angle a and b, to which, however, they may be slightly greater when the profile 16 is not engaged in the juxtaposed grooves 14 and 15, so that the engagement results in a tight fit, with slight elastic compression of the section 16 in the transverse direction, resulting in a slight reduction in width 1 of the slot 23; the struts 27, 28, 32, 33 prevent the application to the wood of the amounts 13 and 12 of a wedge effect by the edges 37, 38, 45, 46

  the profile 16, and thus avoid the risk of explosion.

  wood; to this end, we could also soften

  edges 37, 38, 45, 46 of the profile 16.

  By way of non-limiting example, good results have been obtained by adopting the following values: da = 50 mm f = c = b = 40 mm 1 = 4 mm e = 3.5 gm ca = 74 for a profile 16 extruded aluminum with a length of about 1.25 m, two of these profiles being introduced successively, in the extension of one another, in the juxtaposed grooves such as 14 and 15 panels 1 and 2 a height, that is to say a length of uprights 12 and 13, of the order of 2.50 m, according to the method which will now be described with reference to Figures 1 to 3; these dimensions in length of the profile 16 and in height of the panels 1 and 2 are also given by way of non-limiting example, it being understood however that the present invention relates to the use of double-sided profiles

  dovetail with a length much greater than their trans-

  versales, with possibility of transverse elastic compression within limits to remain low, the width 1 of the slot of the profile 16 having the dimnensions indicated above not being

  for example, subject to variations that are generally

less than a millimeter.

  1 to 3 illustrate the implementation of the profile 16 shown in Figure 4 in the mutual assembly of two panels

  prefabs intended to constitute the walls of a building.

  The panels 1 and 2 are supposed to present beforehand, on their respective edge faces 10 and 11, defined by the faces of the wooden uprights 12 and 13, respective dovetail grooves 14 and 15; the two panels 1 and 2 will also be

  supposed of rectangular plan, with a similar height correspon-

  to the length of the uprights 14 and 15.

  In a first step, any known means is fixed by the means of the craft, on a base 51 made beforehand and for example on foundations, a first panel 1 occupying a position in which its mean plane 20 is vertical, of

  same as its side edge 10 and the groove 14 thereof

  this; if necessary, the panel 1 is attached to another panel, adjacent to its side edge (not visible) edge opposite its face 10 by means similar to those to be described in

  this; this first time is illustrated in Figure 1.

  In a second step, the panel 2, whose plan noyen 21 is also vertical and then coincides with the plane 20, and whose face 11 is applied against the face 10 of so that

  the grooves 14 and 15 complement each other in a closed peripheral channel

  vertical direction 17 defined by the intersec-

  of the combined planes 20 and 21 and the common plane of the faces 10

and 11, as shown in Figure 2.

  As also shown in this figure, is placed above the two panels, in the extension of the grooves 14 and 15 in the direction 17, a profile 16 having the appropriate transverse dimensions, and a length for example close to half of the height of the panels 1 and 2, that is to say half the length of the grooves 14 and 15, and, by pinching

  the lower end 52 of this section 16 with a shrink

  5, the lower end 52 is inserted into the upper end of the grooves 14 and 15 in the mean direction 17 thereof. It is then easy to introduce the profile 16 integrally into the grooves 14 and 15, by applying a downward thrust in the mean direction 17 thereof, conr Te schematically the arrow 54 of Figure 2; the gradual introduction

  of the profile 16 in the grooves 14 and 15 is made by sliding

  the outer periphery 19 of the profile against the

  and flanks of these grooves, with a slight elastic contraction

  of the profile, and can easily be carried out, for example

by means of a mallet.

  When the profile 16 is thus introduced completely,

  its upper end 55 flush with the upper edge faces

  56 and 57 panels 1 and 2, is introduced in a similar manner a second identical section, the lower end pushes down the profile introduced first, as the introduction of the second section; at the end of this introduction, as shown in Figure 3, the upper end of the second section 58 is flush with the upper edge faces 56 and 57 of the panels 1 and 2, while the end

  The bottom of this profile is in contact with the upper end.

  upper 55 of the profile 16 introduced first; the lower end

  52 of the latter is located close to

  the lower edge of the panels, where appropriate

  recessed relative thereto since, generally, it is hollowed out with a groove for receiving a profile 59 for positioning and fixing on the base 51 (see FIG.

figure 1).

  Thus is ensured, throughout the height of the panels, energetic mutual solidarity but nevertheless able to allow the wood amounts 12 and 13 to "work" in time; the positioning of the slit 23 of profiled section 16 and of the similar slit 59 of the profile 58 in the dovetail bottom, ie in the example illustrated at the mid-width of the bottom 29 of the groove 14, is

optimal for this double effect.

  According to an alternative embodiment of the invention, one can use a single section 16 having a length equal to or approaching the height of the panels 1 and 2; one could also use more than two profiles 16, whose cumulative lengths

  would equal or approach the height of panels 1 and 2.

  It will be noted that, advantageously, the interior of the sections such as 16 and 58 can be used as a cable passage

  or the like, and / or filled with a thermal insulating material.

  Naturally, the assembly method just described can be used not only to assemble the vertical edges of panels themselves vertical, but also for any continuous mutual assembly of pieces of wood that are part

integral of panels.

  According to an advantageous embodiment of profiles 16 and

  58 of the illustrated type, these can be made easily extrac-

  tible out of the grooves 14 and 15 to facilitate the possible disassembly of the panels 1 and 2; for this purpose, for example, it is arranged in their wall, at least near their end intended

  to be the most accessible once the editing done, that is to say

  say the extremity 55 with regard to the profile 16 in the illustrated example, two orifices arranged for example according to the plane 53, facing one another, to receive fangs of an extraction device, easily introduced inside the profile and grooves when necessary, to allow, by pulling in the opposite direction to that of the arrow 54 by means of the hooks thus engaged in the orifices, the sliding of the profile such as 16 out of the grooves In a more general way, the invention is capable of numerous variants with respect to the node of corn described

  and represented, without we leave so far from its frame.
