Abstract

PIPELINE ATTACHMENT COLLAR MADE OF PLASTIC MATERIAL WITH HARD ELASTIC WEDDING, AND INCLUDING A MOLDING ROD MADE IN ONE BY MOLDING, SERVING TO FIX THE COLLAR IN HOLES PREVIOUSLY DRILLED FOR THIS PURPOSE IN WALL WALLS, STEM IS INCURREDLY PROVIDED WITH THIN DISC-SHAPED RIBS PROJECTING OUTWARDS, AND WHOSE OUTSIDE DIAMETER IS SLIGHTLY LARGER THAN THE INSIDE DIAMETER OF THE PRESSURE HOLE DRILLED IN THE WALL. THE RIBBED ROD 6 INCLUDES A ROD FORMING AN ANKLE 8 SLOTTED ON ITS LONGITUDINAL AXIS AS WELL AS A LONGITUDINAL BORE 10 WHICH STARTS FROM THE PART OF THE COLLAR FACING THE WALL AND WHICH ALLOWS THE INTRODUCTION OF A PIN OR A WOOD SCREW FOR EXAMPLE. THE PRESENT INVENTION APPLIES IN PARTICULAR TO THE FIXING OF TUBES TO WALLS.

Description

The invention relates to a collar for attaching pipes, made in

  plastic material hard elastic yielding, and having a fitting shaft secured to it by molding, for fixing the collar in holes previously drilled for this purpose in wall walls, cet-tiae Atant in renting provided with ribs in the form of discs protruding from the outside and whose outer diameter is slightly larger than the inside diameter of the fitting hole

the wall.

Such catches of catcher

  These are used primarily for the electric dyes, to fix the sheaths in plastic

  on the walls and ceilings The op lration consists

  pliers to push the rib-shaped rod into

  placed in the holes previously drilled in the ur 'this effect, in which operation the ribs in the form of thin discs fold at their edges in the opposite direction to that of the introduction of the ligea

  and thus confer on the latter a solid blocking of

  held in the wall hole This assumes, however, that the

  the wall around the hole is

  sufficient resistance to deformation, which will be

  the case for concrete or cut stone.

  whether it is plaster walls or plaster walls, this thin disk-shaped rib rod offers little restraint, since such walls are easily crumbled to give these rods collars a sufficient holding force in the case of walls

  made of such materials, this ribbed stem

  door, according to the invention, a dowel rod split in the direction of its length This ridge rod further comprises a longitudinal bore which starts from the wall side portion

  collar, to allow the introduction of an expander organ

  such as a pin, pin or wood screw,

due to the ankle.

Thanks to these provisions, the col-

  tie pipe tie can be attached as well on

  a hard support, such as concrete, for example, than on a

  soft port, plaster or plaster for example In the first case it is simply necessary, to ensure the fixing, to drive the

  ribbed stem in the hole, whereas in the case of

  With the soft support, the necessary retaining force can only be obtained by pressing a stud or screwing a wood screw into the peg. It goes without saying that even in the case of a concrete wall, nothing stands in the way. in addition to using this screw system, if it is considered desirable

  to further increase the holding force of the element

  especially when it comes to posing

  ducts or pipes on ceilings.

The following description of an example

  practical realization of the invention, together with the

  related drawings and to the subclaims

  provided further information on other parts of the

  features of the invention and its technical advantages.

  ribbed ge and expandable ankle.

The collar of canalisa-

  illustrated in the figure plate consists of a

  lower sorting (1) and an upper stirrup (2), which is

  linked, with possibility of opening, to the lower yoke (1) via a thinning hinge (3) on

  one of its sides The stirrup (2) has on its other side

  a hook (4) come from molding which, when closing

  the two parts of the necklace, snap into a

  female antagonist that has the free end of 1 '

  lower bracket (1), both ends of the collar are

  thus linked together by the resulting mechanical action

of their form.

To enable the fixing of

  tie pipe fastener to a wall wall (15),

  it comprises, at its lower yoke (1), a

  rod (6) integral with the latter by molding, and which is

  of ribs in the form of thin discs (7) which

  The outward diameter "Dl" of these ribs

  res is in this case slightly more dimensioned than the inside diameter "of the hole (9) formed in the wall for the fitting of the rod, so that the edges of these ribs (7) during their introduction in the hole (9) fold in the opposite direction to that of the introduction

  stem (see Figure 3) and thus firmly block the

ge (6) in the wall (15).

  In the extension of the ribbed rod (6) is secured to it by molding, a

  expandable ankle split in the direction of its length

  ribbing (6) also comprises, as illustrated by the

  1, a longitudinal bore (10) extending from the inner stirrup

  lower end (1), and which is intended to allow the introduction of an expansion element (11), for example Ain dowel or a screw

  in the split end of the ankle (8).

  The ribbed rod (6) is connected to the bottom of the collar (12), which is applied to the surface of the load-bearing wall, by a rod element (13) of more massive construction, and whose periphery is widening, in a conical pattern from the outside diameter of the shank (6) to the inside diameter of the hole (9) The shank element (13) has sharp-edged ribs (14) disposed on its conical periphery the axis thereof and obtained directly by molding, which are embedded in the edge (16) of the

  hole of the wall (9) during the introduction of the stem forming

  city, and thus prevent the ribbed rod (6) from rotating

  once it is fitted into the hole (9).

  The shaft having the disc-shaped ribs (6) has a wall thickness so small that

  it is able (as shown in Figure 6) to

-2515776

  tighten when tightening the screw (11) This is advantageous in cases where the hole (9) is pierced early in the concrete wall, or as a result of any obstacle could not be pierced exactly to the desired depth, as a function of the length of the ankle, in which case the dowel rod (8) comes into abutment at the bottom of the hole when it is introduced, before the seating surface of the collar (12) In such a case it is possible, using a screw (11) a little shorter, to make come again, by simultaneous deformation of the ribbed rod (6), the lower caliper of the collar (1), until it comes into contact with the wall (15), possibility

  which therefore constitutes another advantage of the invention.
