Abstract

The dust guard comprises a wall(100) intended to close each of the lateral ends (402) of a roller shutter tunnel casing (400). The wall remains protruding relative to the casing lateral end after installing the dust guard. On the wall are ribs (340) and pins enabling its fixing with the construction elements of the masonry (M) positioned facing the dust cover.

Description

The present invention relates to a shutter device made of

  preferably made of plastic, and intended to close each of the lateral ends

  of a rolling shutter tunnel.

  Usually, tunnel vaults are intended to be integrated during construction into the masonry of a building above window openings or

  door, as shown in Fig. 1.

  Each tunnel safe generally consists of a molded shell with a tunnel-shaped recess, the lower part of which is open.

  to accommodate a roller shutter.

  After having been cut to the necessary size, each tunnel safe receives at each of its lateral ends a shutter device constituted

  mainly a cheek and a heel perpendicular to it.

  The length of the tunnel tunnel portion that will be integrated into the masonry

corresponds to the length of the heel.

  The inner faces of the cheeks include holes provided for fixing the

  accessories and an operating mechanism for the axis of the roller shutter.

  The operating mechanism can be a pulley with strap, a winch with

crank or electric motor.

  When maneuvering the roller shutter, its deck rolls up and unwinds around its axis and can thus slide in the slides provided laterally in

  the doorway in order to close or open said doorway.

  The operation of the roller shutter, especially when carried out by an electric motor, generates vibrations in the shutter devices which can

  pass on the walls of the tunnel safe.

  When these vibrations are not properly contained, they can

  generate visible cracks through the exterior wall plasters.

  Installation instructions exist, but are not always observed.

  One solution for correctly anchoring the tunnel safe in the masonry consists in providing, facing the external part of each of the shutter devices, a reserve, for example, by shifting the construction elements by a few centimeters from the cheeks of the tunnel safe, such as concrete blocks used for the formation of

  masonry, then fill this reserve with a binder such as concrete.

  Thus, the shutter devices, and therefore the tunnel safe, can

be anchored in masonry.

2,2803,329

  However, it sometimes happens that the concrete block adjoining the outer part of a cheek is brought into direct contact with it, and without any binder being

  subsequently interposed between them.

  In addition, the outer face of the cheek is most often arranged in a recess in the tunnel safe, so that, even when binder is added to the reserve located between the breeze block and the obturating device, it sometimes happens that the binder

  cannot enter said recess.

  The object of the invention is therefore to propose a shutter device for a tunnel safe for rolling shutters which allows it to be anchored and that of the safe-tunnel in the masonry, in such a way that the vibrations induced by the operation of the

  mechanism are transmitted and absorbed in the masonry.

  To this end, the shutter device comprising a cheek, said shutter device being intended to close each of the lateral ends of a tunnel-safe for rolling shutters, said tunnel-safe being provided for being integrated during construction into the masonry of a building, in particular by its two lateral ends, to be positioned above the doorway of a window or a door, is remarkable in that it comprises on the cheek means provided to allow its joining by a binder with masonry construction elements

  positioned opposite said shutter device.

  Thus, the vibrations produced during the operation of the mechanism are

  transmitted and absorbed in masonry.

  According to another characteristic of the invention, the means for enabling the shutter device to be joined to the masonry consist of ribs,

  studs and / or stiffening bridges arranged on the outer face of the cheek.

  According to another characteristic of the invention, the cheek of the shutter device is extended in the same plane by a flange intended to be applied on a lateral end of the tunnel tunnel, so as to allow the positioning of the cheek outside of the tunnel safe after the shutter device has been mounted in

  a lateral end of said tunnel safe.

  According to another characteristic of the invention, the cheek ribs are arranged perpendicular to the cheek, and the ribs are parallel

  between them and exceed the studs by their heights.

  According to another characteristic of the invention, the cheek ribs are at least three, of which at least two are provided to be taken from

on both sides in the binder.

  According to another characteristic of the invention, the shutter device is accompanied by internal and external shuttering plates provided for respectively connecting a rib or a leg of the tunnel safe with the sides of the masonry construction elements to create a reserve intended to receive

the binder.

  According to another characteristic of the invention, the internal shuttering plate comprises a fork provided for enclosing a lateral rib, said fork being connected to a corner allowing its positioning on an edge of the element

masonry construction.

  According to another characteristic of the invention, the external shuttering plate comprises a base which can be positioned against a leg of a tunnel safe

  and against the outer wall of the masonry construction elements.

  According to another characteristic of the invention, the internal and external shuttering plates each comprise at least one orifice intended to allow the passage of a link provided for temporarily holding said shuttering plates in position between the tunnel safe and the elements of masonry construction

  during the pouring of the binder into the reserve.

  According to another characteristic of the invention, a sheath passage is provided in the cheek outside the ribs to allow the connection of a sheath

  electric, after the shutter device has been integrated into the masonry.

  The features of the invention mentioned above, as well as others,

  will appear more clearly on reading the following description of an example of

  realization, said description being made in relation to the accompanying drawings, among

  which: Fig. 1 shows a side view of a tunnel-safe integrated in a masonry M above a doorway of a building according to the invention, FIG. 2 shows a front view of a shutter device mounted in a roller shutter tunnel according to the invention, FIG. 3 represents a side view in section of a shutter device mounted in a tunnel-safe for rolling shutters according to the invention,

  Fig. 4 shows a rear view of a cheek of a shutter device according to the invention, and FIG. 5 shows a top view in section of a shutter device

  mounted in a rolling shutter tunnel according to the invention.

  The tunnel safe 400 shown in FIG. 1 is intended to be integrated into the masonry M above the doorway of a window or door of a building. It is in particular embedded in the masonry M by its two lateral ends 402 and 404 and by the arch V. It is integrated in the masonry M in such a way that the internal recess

  of the tunnel-safe 400 opens into said opening.

  The shutter device D shown in FIG. 2 is globally constituted

a cheek 100 and a heel 300.

  The shutter device D is intended to be mounted laterally in each of the lateral ends 402 or 404 of a tunnel safe 400 so as to seal in an airtight manner coming from the internal recess of the tunnel safe, said tunnel

lateral end 402 or 404.

  The tunnel safe 400 is represented by honeycomb cells with

Figs. 2, 3 and 5.

  In Fig. 2, the tunnel safe 400 consists of a polystyrene-based shell delimited in length by two lateral ends 402 and 404. A single lateral end 402 is visible in this FIG. The internal recess of the tunnel-safe 400 has the form of a tunnel, the vault V of which is connected on either side to two legs J1 and J2, the thicknesses of which may be different. In this case, the J2 thicker jamb is placed towards

  the internal part of the building to form thermal and sound insulation.

  Two aluminum reinforcement profiles 406a and 406b overlap

  respectively the ends of the legs J1 and J2.

  The cheek 100 of the shutter device D comprises a support edge 110

  arranged perpendicularly on a plate 120.

  The support edge 110 of constant thickness consists of an arch 112

  extended by two straight segments 114a and 114b.

  The support edge 110 is provided to closely match the internal walls of the arch V and of the legs J1 and J2, so as to ensure the

2803329

  precise positioning of the cheek 100 relative to a lateral end 402 or 404

of tunnel safe 400.

  At least one orifice 130 visible only in FIG. 3 is made in a straight segment 114a or 114b to allow the passage of the winch control axis or the strap of the pulley of the operating mechanism. In Fig. 2, the support edge 110 is connected perpendicularly to the plate 120, the internal face of which is visible in this FIG. The plate 120 includes housings 122 designed to accommodate the accessories of a roller shutter axis of a suitable model and its mechanism

maneuver.

  A duct passage 124 is provided in each lower corner of the plate near the straight segments 114a and 114b to allow connection

a standard electrical sheath.

  This electrical sheath is intended to power an electric shutter motor.

rolling.

  The sheath passage 124 is located outside the field of the winding diameter C

of the roller shutter deck.

  The plate 120 is extended at its periphery in the same plane by a

  flange 126 perpendicular to the support edge 110.

  The flange 126 is intended to come into contact with a lateral end 402 or 404 of a tunnel safe 400 to serve as an axial stop for the shutter device D during its mounting. Therefore, it is also able to form a tight barrier to the passage of air between the internal recess of the tunnel safe 400 and a

  insulation lining inside the building.

  Due to this construction, the plate 120 of the cheek 100 remains in prominence relative to the lateral end 402 or 404 of the box 400 after the assembly of the shutter device D. A heel 300 is connected in the lower part of the plate 120 d 'a cheek 100

  and perpendicular to said cheek 100.

  The heel 300 is intended to support the mass of the rolling shutter attached to the plate 120 of the cheek 100 by bearing on the seat of the masonry M, provided at

this effect.

  The heel 300 also makes it possible to support the tunnel tunnel 400 during its integration into the masonry M.

  In Fig. 3, studs 132 are formed on the external face of the plate 120.

  These studs 132 incorporate the housings 122. These housings 122 visible on the face

  internal of the plate 120 in FIG. 2 open inside these studs 132.

  Some of these studs 132 are interconnected by stiffening bridges 134, as shown in FIG. 4. Ribs 340 bevelled at their ends and protruding by their heights the studs 132, as can be seen in FIG. 3, are arranged perpendicularly on the external face of the plate 120 parallel to the

straight segments 114a and 114b.

  The number of these ribs 340 is at least three. Four ribs 340

are shown in FIG. 4.

  The ribs 340, the studs 132 and the stiffening bridges 134 are provided to allow the fastening device D to be secured with a binder, for example concrete, during the integration of a tunnel-safe 400 into the masonry M d ' a

  building, as shown in Fig. 5.

  In this Fig., There is shown in thin lines a masonry M in which it is planned to integrate a tunnel-safe 400 provided at each of its lateral ends 402 and 404 with a shutter device D. A masonry construction element M, for example a concrete block or a brick, is positioned a few centimeters from the external face of the cheek 100 of each of the shutter devices D when the masonry is raised M.

  Typically, this distance should preferably be between 2 and 4 cm.

  Internal 450 and external 460 shuttering plates are placed laterally to the cheek 100 so as to be able to bear on the lateral sides of said construction element to form a reserve R between the cheek 100 and the construction element. This reserve R then allows the binder to be received, for example concrete. The internal formwork plate 450 comprises a fork 452 which can enclose a lateral rib 340 over all or part of its height. The fork 452 is connected to a corner 454 allowing the positioning of the plate

  internal formwork 450 on an edge of said construction element.

7 2803329

  The external formwork plate 460 comprises a base 462 which can be positioned against the jamb J1 and against the external wall of said construction element. The two formwork plates 450 and 460 each have one or more orifices 464 intended to allow the passage of a link provided for temporarily holding in position the two formwork plates 450 and 460 laterally to the cheek 100 during the casting of a binder in the reserve R. Thus, in FIG. 5, three of the four ribs 340 can thus be taken

on both sides in the binder.

  Other orifices 466 are also provided through ribs 340, offering the option of passing the links holding the formwork plates 450 and 460 in place. In this Fig. 5, it will also be noted that the sheath passage 124 is situated outside the ribs 340 to facilitate the connection of the sheath of the electric motor of the roller shutter by an insulating doubling zone I of the walls shown

in checkered lines.

  A tunnel-safe 400 for a rolling shutter is provided at each of its lateral ends 402 and 404 with a shutter device D. The box 400 is placed on the foundations of the masonry M above a recess of a window or

  of a door when raising the masonry M of a building.

  Construction elements are positioned a few centimeters from the external face of the cheek 100 of each of the shutter devices D. Preferably, the construction elements are not brought into contact with

the ribs 340 of the cheek 100.

  The internal 450 and external 460 shuttering plates are positioned laterally to the cheek 100, then fixed by a link to form a reserve R between the

  plays 100 and the building element.

  This reserve R is then filled with a binder which will envelop the studs 132, the stiffening bridges 134, as well as the ribs 340 located on the external face.

of plate 120.

  During its solidification, the binder will trap the studs 132, the stiffening bridges 134 and the ribs 340, which will mechanically link the shutter device D with the masonry M.

  The vibrations produced during the operation of the roller shutter mechanism installed on the shutter device D are transmitted into the masonry M and absorbed by it, due to the anchoring of said shutter device D in the masonry M. Consequently, the shutter devices D no longer vibrate. The same applies to the tunnel safe 400 mounted between said shutter devices D, which

  eliminates the risk of cracks forming in plasters.

  The electrical connection of the roller shutter motor is possible after the shutter device has been integrated into the masonry M.
