Definitions

  • the present invention relates to a formwork and to a method for forming a lamp incorporated in a plasterboard wall or in a wall made of fiber-cement sheets or in a wall made of materials for on-site construction to be clad, for example made of hollow bricks or concrete.
  • One object of the present invention is therefore to bridge such a gap by proposing an assembly and a method that can allow for the installation of a lamp in a plasterboard wall or in a wall made of fiber-cement sheets.
  • Another object of the invention is to propose an assembly and a method that can advantageously also be used to install a lamp in a wall made of materials for on-site construction to be clad, for example in hollow bricks or reinforced concrete.
  • Another object of the invention is to propose an assembly and a method that also make it possible for a non-specialized operator, for example the same plasterboard installer or bricklayer, to incorporate a lamp in a plasterboard wall or in a wall made of fiber-cement sheets or in a wall made of materials for on-site construction to be clad in a manner that is quick, safe and at the same time very precise.
  • 1 indicates, as a whole, an assembly for forming a lamp incorporated in a plasterboard wall 2 or in a wall 3 made of fiber-cement sheets or in a wall 4 made of materials for on-site construction to be clad.
  • the assembly 1 comprises a lamp body 10 and a formwork 20.
  • the lamp body 10 houses a light source 12.
  • the formwork 20 defines a rebated front wall 22 suitable to be attached to the inner side of a plasterboard panel 2' or a panel 3' made of fiber-cement sheets or cladding 4' of the wall 4 to be clad.
  • the formwork 20 also defines a light-emitting cavity 24 that forms a seat 26 at the back for housing the lamp body 10 and a light-emitting opening 28 at the front in the front wall 22.
  • the light-emitting opening 24 is delimited by a peripheral frame 30 that extends perpendicularly from the front of the front wall 22 and such that the front edge 30' of the peripheral frame 30 is flush with the outer side of the plasterboard panel 2' or the fiber-cement sheet 3' or of the cladding 4' of the wall, as shown in Fig. 6 , 7 and 11 .
  • the light-emitting cavity 24 is delimited at the bottom by an inclined surface 32 towards which the light generated by the light source 12 is projected and which ends in the light-emitting opening 28.
  • the lamp body 10 when positioned in its housing seat 26, is not only arranged in a withdrawn position with respect to the light-emitting opening 28, but also in a raised position such that an observer stood in front of the wall 2, 3, 4, is not blinded by the direct light of the light source 12 ( Fig. 10 ).
  • the formwork 20 is also provided with retaining means 34 that cooperate with the inclined surface 32 in order to hold a cladding sheet 5 of the inclined surface 32.
  • This cladding sheet 5 can be made from the same material as the wall (plasterboard, fiber-cement, cladding), and can therefore be obtained and installed by the same plasterboard installer or bricklayer, or from a different material.
  • the cladding sheet 5 can be made of anodized aluminum and can be supplied together with the formwork 20.
  • Fig. 9 shows a few examples of cladding sheet 5a, 5b, 5c that can not only differ in terms of materials but also shape.
  • the cladding sheet 5b has a concave upper side rather than a flat one.
  • the formwork 20 is formed as one piece having an extruded profile 21.
  • the assembly 1 can comprise two side caps 40 suitable to close the open ends of the extruded profile 21 so as to form the lateral sides of the light-emitting cavity 24.
  • the formwork formed as an extruded profile 21 can have a longitudinal extension that is much greater than its vertical dimension, or a plurality of formworks can be brought together without side caps so as to form a continuous linear lamp. In this case, the side caps 40 would not be necessary either.
  • the formwork 20 is provided with a wall 41 at the front for closing the light-emitting opening 28.
  • This closing wall 41 can easily be moved by the peripheral frame 30 once the formwork 20 is placed on-site, for example on account of the reduced thickness of its edge that connects to the peripheral frame 30.
  • the closing wall 41 protects the light-emitting cavity 24 during the steps of installing the formwork 20 and stiffens the structure itself of the formwork 20.
  • the closing wall 41 prevents the weight that can bear down thereon from tending to squash the light-emitting cavity 24, which would thus impede the subsequent insertion of the lamp body 10.
  • the light source 12 comprises one or more LED light source cables mounted on a printed circuit board 12'.
  • the lamp body 10 comprises, in addition to the light source, electrical and/or electronic circuits for controlling the light source.
  • the lamp body 10 is also intended for receiving a power supply 13 and an electrical connector for electrically connecting to power supply and/or control cables.
  • the lamp body 10 may also comprise optical elements for controlling the light beam generated by the light source 12.
  • the lamp body 10 is also provided with heat dissipation means for the heat generated by the light source.
  • the lamp body 10 and the light-emitting cavity 24 are dimensioned so as to allow the lamp body 10 to be inserted into the housing seat 26 through the light-emitting opening 28 and the light-emitting cavity 24.
  • the lamp body 10 is insertable into its housing seat 26 by a snap fit.
  • the walls of the formwork 20 that delimit the housing seat 26 form undercuts 26' that engage with corresponding resilient tabs 11 made in the lamp body 10.
  • the extruded profile 21 forms, in the rear portion of the light-emitting cavity 24, a longitudinal retaining wall 42 that extends from a rear wall 44, substantially in parallel with the inclined surface 32, and has an upper side shaped suitable for snap engaging with the lamp body 10 and an end tooth 44' that can interact with the cladding sheet 5 of the inclined pane.
  • the cladding sheet 5 of the inclined surface 32 is provided with fastening means 5', for example a fastening tooth, which cooperate with the retaining means 34 and also comprise a hole, for example, in which the fastening tooth can engage so that said cladding sheet is fastened to the inclined surface 32.
  • fastening means 5' for example a fastening tooth, which cooperate with the retaining means 34 and also comprise a hole, for example, in which the fastening tooth can engage so that said cladding sheet is fastened to the inclined surface 32.
  • the cladding sheet 5 has a lower end that is counter-shaped to the lower side of the peripheral frame 30. In particular, this lower end is cut so as to form a horizontal support base that rests against the horizontal lower side of the peripheral frame 30.
  • a rear opening 46 is made in a rear wall of the formwork 20, which delimits the housing seat 26 of the lamp body 10, suitable for the passage of the end of a corrugated tube 50 that can carry the electrical power supply/control cables for the lamp body 10.
  • the installation of the assembly 1 in a plasterboard wall 2 or in a wall 3 made of fiber-cement sheets is carried out as follows.
  • a window 2a; 3a is made in a plasterboard panel 2' or in a fiber-cement sheet 3', which has dimensions that correspond to the light-emitting opening 28.
  • the electrical power supply/control cables of the lamp are brought in the proximity of the region where the lamp is positioned.
  • the formwork 20 is fixed to the inside of the panel or sheet so as to pass the peripheral frame 30 through the window 2a; 3a.
  • the formwork 20 is fixed by means of screws and/or glue applied to the front wall 22 of the formwork 20.
  • the panel or sheet is fixed to the bars 60 of the frame of the plasterboard or fiber-cement wall.
  • the electrical cables are connected to the lamp 10.
  • the lamp body 10 is fastened to its housing seat 26.
  • the method is carried out as follows.
  • the electrical power supply/control cables of the lamp are brought in the proximity of the region where the lamp is positioned.
  • a recess 70 is made in the wall that is suitable to house the formwork 20 and the electrical cables are therefore pulled inside this recess 70.
  • the formwork 20 is inserted into the recess 70 so that the peripheral frame 30 protrudes with respect to the outside of the wall that is not clad such that the front edge 30' of the peripheral frame 30 will be flush with the outer side of the cladding once it has been glued to the wall.
  • a layer of cladding adhesive 72 is applied to the wall to be clad and to the front wall 22 of the formwork such that said walls are coplanar.
  • the cladding can be applied to the wall and a cladding sheet 5 can be positioned on the inclined surface 32.
  • the electrical cables are therefore connected to the lamp body and the lamp body is attached to its housing seat.
  • a spacer 80 for example in the form of an extruded profile screwed to the front wall 22, can be arranged between the front wall 22 of the formwork and the inner side of the panel, sheet or cladding.
