Definitions

  • the present invention relates to a device for fixing under a slab, for a railing support bar, in particular for a balcony railing.
  • Balcony railings generally include support bars, which support a handrail as well as a filling or a railing, the base of each support bar being fixed to the balcony slab.
  • the base of each support bar is placed and fixed on the upper surface of the balcony slab, a short distance from the front edge of the slab, called "slab nose".
  • This traditional method of fixing has certain drawbacks, in particular: the means of fixing the support bars are very exposed to the weather, their presence on the upper surface of the slab can represent an annoying obstacle, and they weaken the region of the slab nose. .
  • under-slab fixing devices for railing support bars have already been proposed.
  • a fixing is produced which is better protected from humidity, while completely freeing the upper surface of the slab.
  • the means for fixing the support bars can be placed at a greater distance from the slab nose, thus avoiding the embrittlement of this part, which is advantageous in particular in the case of the renovation of old buildings.
  • German patent application DE-A-4324602. This device uses a particular horizontal piece which is applied, and fixed by screws, under the underside of the balcony slab. At the front of this part is provided a vertical element on which fits, without possibility of adjustment, the base of the railing support bar. The angular adjustment is carried out by means of a small mobile shim placed on the horizontal part. This part is therefore not applied, by a large continuous surface, against the underside of the slab.
  • the adjustment device of document DE-A-4324602 does not allow the compression load to be distributed over an appreciable continuous surface on the concrete, which results in instability of the railing when the support bar is stressed. We will also note that, in this document, the positioning of the adjustment shim appears difficult.
  • the present invention aims to eliminate all these drawbacks, by providing an improved sub-slab fixing device, which while retaining a simple and economical structure allows adjustments in all directions, this in a convenient manner with access from above the slab. , and also allows an optimization of the mechanical connection and of the transmission of forces, between the components of the fixing device under the slab and the slab itself.
  • the invention provides a device for fixing under a slab, which requires a minimum number of components, while allowing adjustment in all directions by the cooperation of two complementary surfaces, spherical or the like, making it possible to compensate for the geometric defects of the slab. and always place the support bar in the desired orientation.
  • the fixing device under the slab, object of the invention makes it possible to place the support bar not only in a vertical position, but also in an inclined position which may be necessary in certain cases, in particular when a gutter must be placed in front of the slab nose.
  • the sub-slab fixing profile is positioned in such a way that its front end, and consequently the end piece with a convex outer surface, are located in front of the slab nose, which saves the space necessary for the gutter.
  • the fixing profile under the slab is positioned so that its front end, and therefore the end piece with convex external surface, are located practically at right of the slab nose.
  • this under-slab fixing device in particular of its shoe, it can be used with existing support bars, in particular support bars constituted by a simple straight profile, the upper part of the shoe comprising a housing open upwards, receiving the base of the support bar.
  • the position provided for the adjustment means makes it possible to directly apply the fixing profile under the slab against the underside of the slab, without the interposition of any shims, which provides a large contact surface on which the forces are distributed.
  • the fixing profile under the slab has a flat upper face, pressing against the lower face of the slab. It is for example a tubular profile having a generally semi-circular section.
  • This profile may include a relatively massive internal part, intended to be pierced vertically at the location of the or each screw for fixing to the slab.
  • the sub-slab fixing profile may also have, in the lower region of its outer wall, a cut made in correspondence with the location of the fixing screw, this cut being able to be closed. by fitting a cover.
  • the means for fixing the shoe against the end piece consist of a single fixing screw, passing through said end piece and tightened in a longitudinal channel of the fixing profile under the slab, formed in the relatively massive internal part of this streamlined.
  • the concave base of the shoe has, in its middle, a buttonhole opening for the positioning of the shoe on the fixing screw already in place.
  • the base of the shoe still advantageously has, in its front part, an opening allowing access to the fixing screw, the opening in question being able to be closed by the installation of a cover.
  • the shoe fixing screw is pre-mounted, and the positioning of this shoe, followed by its adjustment and its blocking in the adjusted position, is easily carried out from above the slab. It will also be noted that the adjustment in all directions is carried out at a single point. Once the shoe has been adjusted and tightened, the installation of the cover conceals and protects the fixing screw, while leaving it accessible after removing the cover.
  • FIG. 1 shows, in cross section, a balcony slab 1 whose front edge 2 forms the "slab nose".
  • the balcony slab 1 receives a railing, generally designated by the reference 3, which comprises rectilinear support bars 4 arranged at intervals, the summits of which support a handrail 5.
  • the railing 3 also comprises a filling 6, mounted between an upper rail 7 and a lower rail 8 which are both fixed to the support bars 4 by appropriate connecting pieces, respectively 9 and 10.
  • the bars -supports 4, the handrail 5 and the rails 7 and 8 are formed by aluminum alloy profiles.
  • the support bars 4 are fixed vertically, and situated just in front of the filling 6, itself placed in the vertical plane passing through the slab nose 2.
  • Each support bar 4 is fixed under the slab 1, by means of a sub-slab fixing device designated as a whole by 11 and described in detail below, the base of this support bar 4 thus being located just in front of the slab nose 2.
  • the same fixing device under the slab 11 also applies to a support bar 4 slightly inclined on the vertical, the base of the support bar 4 being offset to the front so as to allow the fixing of a gutter 12 against the slab nose 2.
  • the filling 6 of the railing remains located in a vertical plane passing through the nose slab 2, the bottom rail 8 of this filling 6 being connected to each support bar 4 by a substantially horizontal connecting rod 13.
  • the device 11 mainly consists of a fixing profile under the slab 14, an end piece 15 mounted in front of the profile 14 and a shoe 16 fixed against the end piece 15 and receiving the base of the support bar 4.
  • the fixing profile under the slab 14 is a tubular profile, of symmetrical section having a generally semi-circular shape, its large flat face 17 being applied under the lower face 18 of the slab 1.
  • This profile 14 has internal longitudinal partitions 19, dividing it internally into two lateral chambers 20 and 21, and an intermediate chamber 22, the latter having a substantially square section - see FIGS. 4 and 5.
  • the profile 14 also has a relatively massive internal part 23, pierced longitudinally with a channel 24 of circular section.
  • the profile 14 is fixed under the slab 1 by means of a vertical screw 25, located at a predetermined distance D from the slab nose 2.
  • a vertical screw 25 located at a predetermined distance D from the slab nose 2.
  • the solid part 23 of the profile 14 is pierced perpendicular to the channel 24, as indicated at 26 (see FIGS. 3 and 4), so as to provide a vertical passage for the screw 25.
  • the lower region of the wall substantially semi-cylindrical 27 of the profile 14 is cut locally, as indicated at 28, forming a "window" through which the intermediate chamber 22 of the profile 14 opens outwards.
  • the end piece 15 has a convex outer surface 29, in particular in a spherical cap. This end piece 15 extends perpendicular to the longitudinal detection of the profile 14. It is fixed against the front end of this profile 14.
  • the shoe 16 clearly visible in FIGS. 3 and 6, has a concave base 30, in particular in a spherical crown, complementary to the external surface 29 of the end piece 15.
  • the upper part of the shoe 16 forms a housing 31 open upwards, receiving the base of the support bar 4 which is immobilized therein by means of a blocking wedge device known per se (not shown).
  • the concave base 30 of the shoe 16 has, in its middle, a buttonhole opening 32 intended to be crossed by a fixing screw 33, which also passes through the end piece 15 and which is introduced and tightened in the channel 24 of the profile 14 In its front part, the base 30 of the shoe 16 has a rectangular opening 34, allowing access to the head of the fixing screw 33.
  • the shoe 16 is applied, by its concave base 30, against the convex external surface 29 of the end piece 15.
  • the tightening of the screw 33 fixes the shoe 16 against the end piece 15 in the desired relative position, allowing adjustment according to all directions of space.
  • the shoe 16 can thus be positioned and immobilized in a position placing the support bar 4 in a vertical position ( Figures 1 and 3), or in a position placing the support bar 4 in an inclined position ( Figure 2).
  • the fixing screw 33 being placed in advance, without being fully tightened, the shoe 16 is engaged by its buttonhole opening 32 on this screw 33 already in place, which facilitates its installation as well as subsequent tightening of said screw 33.
  • the mounting and adjusting operations of the shoe 16 are thus conveniently carried out by a person taking place on the slab 1.
  • the fixing profile under slab 14 has, between the fixing screw 25 to the slab 1 and its rear end closed by the cover 39, a length L which can be relatively large.
  • the length L is determined according to the requirements prescribed by the standards in force in the country concerned, and by the strength constraints of the fixing device, in particular the characteristics of the dowel 40, embedded in the slab 1, which receives the fixing screw 25.
  • an elongation of the length L therefore of the distance between the screw 25 and the rear end of the profile 14, makes it possible to reduce , by an easily understandable lever arm effect, the forces exerted on the screw 25 and / or on the ankle 40, under the action of the weight of the railing 3 and the external forces transmitted by this railing.
  • This fixing device under slab 11 is applicable to new constructions and to renovation works. It relates not only to the balcony slabs, which are substantially horizontal, but also to the stair climbs with fixing under an inclined surface, the spherical configuration of the end piece 15 and of the shoe 16 making it possible, in all cases of application, to fix the support bar 4 in a vertical or substantially vertical position.
  • this sub-slab fixing device 11 is applicable, without modification, not only to a filling railing 6 as described but also to a railing with bars.
