Abstract

Framework intended to ensure the fixing and evenness of a covering or false ceiling on a support which is regular or otherwise, damp or out of plumb, it is characterised by: a metal clamp (1) whose main face has an orifice in which the fixing screw is engaged, and two wings whose end is folded inwards; a wooden lath (10) having two rabbets on one face and which is cut substantially identically to the clamp (1). The clamp is fixed to the support by a screw, the screwing of which permits compensation of the irregularities of the support, while reserving between these elements a ventilation space into which an insulant can be inserted. The lath is secured to the clamps simply by snapping in.

  Counter-lathing elements and associated means.

  The present invention relates to the elements and means for making a mid-batten for receiving the fixings of any coating or false ceiling for example. As a rule, such a counter-lathing is carried out by means of metal hangers which are engaged on a fur by

  one of its ends, sliding them on it

  in position where one executes their attachment to the support.

  The implementation of this counter-lathing mobilizes at least two people, one supporting all or part of the fur while

  that the other executes the subjection of the lines to the support.

  According to a known type of embodiment, this drawback has been remedied by means of suspension whose configuration of the head authorizes their subjection to the fur by snapping

  direct in any place of it.

  In this way, a person can perform the fixa-

  suspension, then snapping on the fur

  which then receives the attachment of the coating to be laid.

  When equipment must be interposed between the support

  hangers and the hanging surface, such as an insulation layer

  For example, one finds oneself limited to the use of a material

  sufficiently flexible and compressible so that it can absorb the

  the lines without too much difficulty.

  In this case, and in addition to its role of supporting the coating

  to hang, the fur is used to hold the insulation layer in place

  te, made of glass wool or rock in general.

  The presence of the lines prior to laying the cou-

  insulating che creates a number of constraints for it.

  In addition, the simultaneous laying of the insulating layer and the fur that maintains it, mobilizes at least two people and

suppose a certain experience.

  Thus, this type of counter-lathing is not compatible with insulation panels made of rigid material, such as for example the panels described in the patent application.

  - 2 - Finally, the counter-slats associated with this type of suspension are usually metal and therefore require the use of special screws called self-drilling, and prohibit the use of

  nails and staples which can be used for fixing certain

  clothing. The present invention generally aims to

  to remove these difficulties, and in particular to allow only one

  the person to carry out a counter-lathing on an insulating layer de-

  laid, as well as being able to use traditionally

  inexpensive (wood screws, nails, staples).

  More specifically, it concerns elements of counter-

  and the means associated with it.

  In the first place, it aims at a horseman,

  is characterized by being subject to the support of the counter-

  lathing by a screw to adjust the spacing, and it has on the one hand, in the center of its main face an orifice of which

  the thinned edge projecting outwards and cut perpendicularly

  rally, allows the forced extension of its diameter to that of the body of the screw during the introduction thereof, while opposing its withdrawal, and whose periphery is shaped to the screw head

  to fit in, and on the other hand two symmetrical lateral wings

  resulting from the square folding of its main face, the ex-

  free ends of these wings being folded towards each other at

acute angle.

  According to an alternative embodiment, the rider comprises

  instead of the orifice and its periphery, a passage ta-

  raudé protruding outward, and associates with a screw whose end shaped to allow the grip of a tool is threaded

to the same standards.

  The rider is intended to maintain a counter-lath of wood, agglomerated wood particles, plastics or

  any other similar material whose cross-section is sensi-

  rectangular and characterized in that its width and thickness

  are substantially the same as the inner dimensions of the

  valier to accommodate easily, and in that it has on one of its faces, two identical rabbets, whose bottom is parallel and

  and the flank perpendicular to that face, intended to receive the ex-

  folded trammel of the rider's wings.

  Due to the nature of the material used, the counter-lattice

  you accept most traditional fasteners (wood screws, nails, staples), and its cost is significantly lower than that of metal furs, while its thermal qualities

and phonic are superior to him.

  According to a preferred embodiment, each of the rider's wings form a same obturated angle with the main face which constitutes their common base, while the small faces of the counter-batten form an angle at least equal to the face opposite to

the one with the rabbets.

  This provision facilitates the introduction of the counter-lat-

  te in the rider, allows a progressive separation of its wings and a more marked pinching of these on the counter-batten during

  of their return to their original position.

  To unite and align the counter-slats by their ends, the invention also relates to a jumper characterized in that its main face has only one or two abutments obtained by cutting in said face of a figure folded to the square towards interior

  and in the longitudinal axis of the rider.

  When the counter-lathing requires the use of long screws positioned obliquely or horizontally, it may be necessary

  to increase their resistance to bending by means of a metal piece

  lique characterized in that it is in the form of a truncated cone whose large base is serrated on its circumference, while the other end, which has or not a return to the inside,

  is split axially in several parts of its periphery.

  According to an alternative embodiment of this piece of

  strong, its small base gives birth to a small cone, inverted by

  port to the first and located inside of it, split in the

  axial direction in several places of its periphery.

  So, its big base rests on the support and the teeth

  opposed to its rotation.When introducing the screw by screw-

  wise. The rod of the screw is strongly constrained in any 4 place by the forced extension of the diameter of the orifice located at

the small base.

  In this way, this metal piece plays a leg role

  by force on the screw that runs through it.

  To facilitate the implementation of the counter-lathing with rigid insulation panels known per se, of the kind comprising a body of rigid material, a face has a notch or a groove for cooperating with the support of the counter-lathing, such as a crawling frame element for example, these include,

  at the right of said notch or groove, perforations or sim-

  punctures leading to the opposite face where they are

  such as marking, for example, arranged at regular intervals

  and intended to receive and guide the counter-lathing screws.

  In order to prevent the counter-lathing protruding

  insulation panels, these have trans-

  versales, whose dimensions are greater than those of the counter-

  latte so that it takes place easily on the opposite side to that having the notch or groove for cooperating with

  the structural member serving as a support for the counter-lathing.

  According to a particular embodiment of these panels, they have a longitudinal groove, the dimensions of which are greater than that of the counter-batten so that the latter

  easily lodges, right and in the opposite face to the notch or rai-

  to cooperate with the structural member serving as a support

port to counter-lathing.

  This type of panel allows a vertical counter-lathing for

  the installation of paneling for example, horizontally.

  Thanks to this configuration where the counter-batten is positioned

  not in the grooves provided for this purpose, we gain in habitability

the thickness of the counter-batten.

  The invention will now be described in a mode of use.

  The mode of use as it follows uses the attic insulation panels described in the patent application.

  number 85 - 18180 - filed on December 9, 1985 in the name of the same inventor.

  These panels comprise a body of rigid insulating material

  of parallelepipedic general shape, which presents on one side

  a rectilinear groove calibrated to cooperate with an element of char-

  corresponding creeping slope, secured on one of its lateral faces 6 at least to a band of easily compressible insulating material of

  length and thickness substantially identical to hers.

  According to the present application, these panels (40) comprise

  furthermore perforations or simple punchings (41) which allow

  guide the counter-lathing screws to their anchorage. These perforations are made at regular intervals and in line with the groove (45) intended to receive the chevron, so that

  the user is thus exempted from taking and

sures and landmarks.

  When the screws used deserve to be reinforced at

  their shear point, the reinforcement pieces (30) are

  to the installation of the panel, forcibly introduced, point forward, in the perforations intended to receive a screw, by the bottom of the

  groove (45) for receiving the crawling frame member.

  After the panels have been nested on the

  In this case, the screws are engaged in the hole (4) of the jumpers (1) and pressed forcibly until the screw head is received in the recess (6) shaped for this purpose. The design of the orifice allows its expansion to the diameter of the screw, by clamping it and opposing its withdrawal. Each of a jumper (1), the screws are engaged in the holes (41) marked as needed on the face of the panels by marking for example, until coming to a stop against the chevron

  or against the small base of the reinforcement cone (30) when it has been

lablement introduced.

  They are then screwed into the rafter until

  which, for example, determines a taut cord, so that the

riders (1) are coplanar.

  During this operation, the wings (3) of the rider (1) are held between the fingers to prevent the simultaneous rotation of the rider and the screw, the thinned edge of the opening (4) sketching of

  so a circular throat primer on the shank of the screw.

  The counter-batten (10) is presented in front of the riders (1),

  then pushed from place to place to constrain the wings (3) of the

  valier (1) to deviate from each other, and allow the passage of

  the counter-batten (10) until the rebates (15) are

  keep folds (7) of the wings that come to stay there by taking 7-

  elastically their initial position.

  At the same time, the counter-lath (10) is part of the

grooves (42) or (43) of the panels.

  It is connected to the next by its end by means S of a jumper (l) having one or two stops (8) in the middle:

  It is slid on the counter-batten as far as the stop, and the counter-

  next batten is engaged on the same rider until

in abutment.

  In this way the alignment and the cohesion of the counter-slats

between them are insured.

  In another embodiment of the invention,

  use of riders (1) having a threaded passage (9) protruding

  outwardly, instead of the orifice (4) and its

phery (6).

  s15 We then use screws (20) whose shaped end

  to allow the grip of a tool is threaded (21).

  The screws are inserted into the perforations (41),

  in the rafters and adjusted before securing the riders

(1) by simple screwing.

  All the operations that have just been designated can

  advantageously be carried out by one person.

  Of course, the invention is not limited to the modes of

  realization that have just been described and represented.

  Many changes can be made to

  tail without departing for that of the scope of the invention.
