Description

The invention relates to a method of constructing a lightweight structure for supporting bearing elements such as cables or ducting as well as aids for use in constructing the structure.

5 To support such elements, it is known to use cable guides which usually comprise a series of U-shaped profiles.

Initially, such profiles have been produced either by bending solid or perforated metal sheets (EP-A-57879) or by bending welded wire meshes (EP-A-10 191667).

Instead of the profiles mentioned, later, for light installations, U-elements are formed which, like a ladder each, consist of two long sides, which are interconnected only by means of traverse, which allow better ventilation of the cables and / or duct pipes. 15 and better access for placement and attachment.

It is usually the case that even when the ends of the traverses are fixed in grooves on the long sides, these ladder-shaped traverses need to be fastened to the long sides by riveting, fastening or fastening (FR-A-2,588,426), which requires considerable mounting time, and the rivets, screws or bolts must be available at the mounting location and some must be lost during assembly.

It is also known to assemble the traverses with the long sides by means of angles, but these also constitute separate parts of small extent, which can be lost in large quantities during mounting and thus appear expensive (FR-A-2,510,682).

To remedy this disadvantage, it is known (EP-A-119670 / DK B 158.429) to have long sides whose facing surfaces each have a rib with mounting zones and blocking zones for the traverses.

30

Precisely the ribs have cutouts in each of which one of the ends of the traverses may engage and be locked practically perpendicular to the surface in which the ribs are located.

The locking in the mounted position of one end of each longitudinal traverse occurs against the fixed surfaces of this long side, but it is effected by the impact of a tongue elastically connected to the ribs.

Lsiv ig / gs £ d i 2

By this method, a ladder is not obtained which is sufficiently rigid to withstand the stresses to which it is subjected, and such ladder may therefore fold or otherwise be deformed away from its planar configuration, thus permitting a displacement of the planar arrangement of cables or wires, which can lead to disconnected connections or 5 short circuits.

While these methods were sufficient for assembling traverses and long sides for metallic profiles, it would still be difficult to apply the methods to traverses and long sides of plastic, especially those made by extrusion.

10

To assemble the U-profiles to form the lightweight construction, it is common practice to use rails or slats.

These are usually designed in such a way that they ensure the joining of the U-profiles either in extension of one another or a characteristic angle in a vertical and / or horizontal plane.

It is also known to perform rails or slats in two parts which are jointed with one another around an axis which is either parallel to their plane or perpendicular to their plane.

In all of these known cases, the rails or lugs are secured to the long sides by bolting or riveting, which again complicates the assembly, having to ensure the proper mutual placement of the various elements until the fasteners are engaged and tightened.

In addition, the fasteners may get lost.

25

The object of the invention is to provide a method of constructing a structure which ensures the rigidity and mounting of the longitudinal traverses without the use of separate parts.

For this purpose, the invention discloses a method as set forth in the preamble of claim 1, and this method is characterized by the characterizing part of claim 1.

The invention also relates to aids as claimed in claims 4-9 for use in the practice of. the method of forming the light structures in question provided with these aids.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be explained in more detail in connection with the drawing, in which: FIG. 1 is a plan view of the light structure in question; FIG. Figure 2 is a larger scale sectional view of the ends of two long sides assembled by means of a rail or groove; 3 is a perspective view showing the mounting of the traverses on a longitudinal side; FIG. 4 is a sectional view taken along line IV-IV of FIG. 1; FIG. 5 is a section along the line V-V in FIG. 1, FIG. 6 is a sectional view of a collector, and FIG. 7 is a perspective view of a two-way assembly.

10 In the drawing, it is seen that the lightweight construction 1, which is intended to support long elements 2, is obtained by joining U-shaped elements 3, each consisting as a ladder of two long sides 4 and 5, which are only interconnected with distance using traversers.

These long sides and traverses are advantageously formed of profiles which are preferably, but not exclusively, made of resin material or composite material obtained, for example, by extrusion.

In a known manner, the traverses preferably have an open tubular cross-section which gives them some ease and elasticity.

The aperture 7 may be located on the side facing the interior of the U-shaped member for accommodating, for example, anchoring elements on fasteners for cables and ducting (not shown), but preferably it is on the opposite side.

In known manner, the long sides, which are open on the faces facing each other, have a longitudinal groove 8 which occupies the ends of the traverses.

This groove 8 has (Figs. 3-5) a U-shaped cross-section, the branches 9 and 10 of which on the facing surfaces can advantageously carry ribs 11 and 12 which engage grooves 13 and 14 in the traverse perpendicular to the traverse length axis 15 and located at a distance D from the end surface 16 of 30 the traverse, which is at most equal to the depth Pj of the groove, measured from the bottom of the groove 8 to the ribs 11 or 12.

Instead of using long sides where the opening in the longitudinal groove 8 has a constant width, and that. introducing the end of the traverses from one of the ends or also by deformation of the groove according to the invention is carried out as follows: - long sides are used, the ribs 11 and 12 restricting an opening having a variable height as you measure it three longitudinally displaced zones, namely:

UIV I V / D I

4. in zones Z-j, where the traverses should be located after mounting, and are therefore called mounting zones, the opening having a height L-j which is at most equal to the distance E- | between the bottom 17 and 18 the rollers 13 and 14 are the front ends of the traverses 6, 5. in a zone Z2, referred to as the blocking zone, which is immediately adjacent to one end of the mounting zone Zj, and the opening having a height which is clearly less than the distance Ej between the bottom 17 and 18 of the grooves 13 and 14, so that the constraints between the two zones constitute abutment surfaces 19 and 20 front face 21 of the traverse, and 10. in a zone Z3, referred to as the engagement zone, which is adjacent to the other end of the mounting zone Zj, extending over a length greater than the width of the traverse and which is itself divided into two zones, of which an outer zone Z4 extends over a length at least equal to the width of the traverse, and an intermediate zone Z5, the opening of the groove having a height L at least equal to the height H of the end of the traverse, and in the middle. the flap zone Z5 a height which preferably decreases gradually from the height L4 of the opening in said outer zone Z4 to the height Lj of the opening in the mounting zone Zj, and - when mounted at a displacement parallel to the axis of the traverse, the end of the traverse is brought into the opening in the the outer zone Z4, whereby the traverse is pushed parallel to the longitudinal axis for clamping between the edges of the opening in the mounting zone Z \ and abutment against the surfaces 19 and 20 provided for this purpose.

Thanks to this mounting procedure, it is unnecessary to have other fasteners such as screws and bolts.

25

Especially in the case where the profiles and long sides are of plastic material and where no subsequent disassembly is expected, of course, in certain cases, gluing of the surfaces which are in contact with each other can be made.

The means according to the invention for initiating the mounting, which comprises said long sides and traverses, are thus arranged in such a way that they do not make use of long sides where the longitudinal opening of the longitudinal note is constant and where the traverse can be arranged at any point in time. the longitudinal direction; instead, this aperture has a variable height, depending on whether one of three longitudinally displaced zones is measured, which varies as follows 35 - in the zones Zj, where the traverses are to be located after the installation, and which are therefore called mounting zones, have the opening a height Lf which is at most equal to the distance E between the bottom 17,18 of the grooves 13 and 14 at the ends of the traverses 6, 5 - in a blocking zone Z2 immediately adjacent one of the ends of the mounting zone Zj, this opening has a height, which is clearly less than the distance E- | between the bottom 17 and the bottom 18 of the grooves 13 and 14 so that the boundaries between the two zones constitute abutment surfaces 19 and 20 for the side surface 21 of the traverse, and 5 - in the engagement zone Z3, which is at the other end of the mounting zone Zj, and which extends over a length greater than the width of the traverse and is itself divided into two zones, namely, an outer zone Zj, which extends over a length at least equal to the width of the traverse, and an intermediate zone Z5 the opening of the groove a height 1.4, which is at least equal to the height H of the end of the traverse, and in the intermediate zone Z5 a height which preferably decreases gradually from the height L4 of the opening in the outer zone Z4 to the height Lj of the opening in the mounting zone Zj.

By way of example, in the case of a traverse with a height of approx. 40 mm, the distance or thickness between the bottom 17 and 18 of the grooves 13 and 14, respectively, in the traverses will be of the order of 37 mm, while for the longitudinal groove, it will have a width of about 15 mm behind the ribs 11 and 12. 41 mm, and the aperture bounded by the edges of the ribs 11 and 12 will be 37 mm in the receiving zone, 34 mm in the blocking zone Z2 and 41 mm in the engagement zone Z4.

20

To form the sides of a U-shaped gutter, the long sides up above the groove which occupy the ends of the traverses are extended in a rib or flange 25 which furthermore gives the long sides a very high bending stiffness.

At its upper edge, the flange may for the same advantage have a horizontal branch 26, this branch 26 and the lower branch 9 defining a side of the groove 8 capable of accommodating a reinforcement of 1x glass fibers.

In conventional fashion, the ladder elements along the long sides are interconnected by means of rails 30 or grooves 30, and these may be planar, straight or angular profiled grooves or grooves in two parts 22 and 23 which can rotate about one axis 24 perpendicular to or parallel to their plane.

Instead of these salmon 30 being secured to the ends of the long sides by bolts or rivets, the invention can be proceeded as follows: - Long sides whose surface 31 is opposite to the surface 36 which abuts against the ends of the traverse have a large lateral T-groove 33, which in translation controls

LSIY 1 D I

6 shows the ends 34 of lugs 30, which thus have two facing faces 35 and 36, the distance of which corresponds to the height of the lug, and surfaces 37 and 38 which are intended to at least indirectly abut the surface 39 on the shank opposite the surface 40 abutting against the outer surface 31 of the flange 25 on the long side, and 5 - inserting the shaft into the T-groove and attaching the shaft to the surface 31 on the flange of the long side.

Preferably, the attachment is by gluing.

10

According to a particular embodiment of the invention, the following is achieved: - It is based on long sides which have at least one side 41 of the two sides 41,42 of the T-note a surface 37, which is intended to abut one of the edges of the surface 39 of the sheet, which surface 37 is at a distance from this surface 39 of a certain value V in such a way that a longitudinal groove 43 with U is formed between the surface and the rim of the slab. -formed cross-section facing the axial portion of the longitudinal side, and whose bottom 44 itself is at a distance from the surface 35 which in the T-note occupies the side surface of the slab with a certain depth P2, which is preferably at least equal to the coverage R of the second edge of the surface 39 of the groove 20 at the opposite side 42 of the T-groove, and - during mounting, forcing into the thus formed U-shaped groove 43 an elongate wedge 45 having a thickness which is at least equal to the width of the U-shaped groove 43, by means of which wedge 45 you hold las can be fixed by crushing.

25 This constriction, in particular, makes it possible to hold the end of the latch against the long side, at least until the adhesive is completed.

Considering the depth of the U-shaped groove 43, the groove can be engaged without the need to insert it from the end of the long side, which is important in the case of mounting in 30 zones with difficult or obstructed access.

Thus, the means for carrying out the construction according to the invention, which comprises ladder elements and lugs 30, are characterized in that the surface 31 is opposite to the surface 32 which lies. at the ends of the traverses has a large T-groove 33 which is open in the lateral direction and guides the ends 35 of lugs 30 in translation.

In particular, the T-notes have two opposite surfaces 35 and 36, the distance corresponding to the height of the slab, and surfaces 37 and 38, which are intended to at least indirectly abut the surface 39 of the slab opposite the surface. 40 in abutment against the flange 25 of the long side.

5 To maintain the end of the groove in abutment against the longitudinal flange, at least until the glue is applied, on at least one side 41 of the sides 41 and 42 of the T-note lies the surface 37 which is intended to lie against one of the edges of the surface 39 of the slab, at a certain distance V from this surface 39, so that a longitudinal groove 43 of U-shaped cross-section facing the axial part of the longitudinal side and the bottom 44 of which is formed between this surface and the rim of the slab even 10 is at a distance from the surface 35 which in the T-note occupies the side surface of the slab, with a certain distance or depth P2, which is preferably at least equal to the coverage R of the second edge of the surface 39 of the slab at the opposite page 42 of the T-note.

In the case of articulated joints, during assembly, it will be ensured that welding parts 15 22 and 23, which belong together in pairs, are always made, and for this purpose the interacting parts of the joints are manufactured in a single piece which is split by sawing before assembly or by a hammer strike in a place where there is a bride showing.

The lugs 30 are made, for example, in the form of a plate, which in its middle part has a guide for breaking into two parts 20 and 23, each having at one edge a part of guiding elements 24 such as an open hinge and at the other part a component with complementary cross-section for recording the hinge.

In the case of articulated joints, after installation the joint can be blocked in the mounting angle in any known manner, such as by gluing and / or stapling.

For purposes of connection in more than two directions, the means of the invention further comprise connecting means 50, on one of their faces, a groove 51, similar to the groove 8 in the long sides for receiving the ends of traverses, and having on their opposite surface shapes. 30 suitable for engaging and longitudinal sliding movement in the groove 8 of the long sides for accommodating the traverses.

The connecting member 50 also has grooves 52 and 53 for receiving ribs 11 and 12 on the longitudinal groove 8, but the distance E2 between the bottom portions 54 and 55 of these grooves is at least 35 equal to the height L2 of the opening of the groove 8 in the blocking zone 22 on the long side.

With this connecting member 50 is connected in a known manner at an angle A corresponding to the angle at which another long side is to be attached, at least one fastening means 56, similar to the means 50, which engages the groove in the long side to be fixed.

Between the ends of the longitudinally connected longitudinal sides there may be added grooves which prevent any solution of the continuity of the sides of the cableways.
