Definitions
- the present invention relates to a method of installing a set of ceiling panels to a basic ceiling to obtain a suspended ceiling.
- Suspended ceilings are generally known in the art. In most cases suspended ceilings are installed by use of a grid of metal beams in the form of inverted T-sections to support the ceiling panels.
- the panels used in known suspended ceilings are of various materials, such as mineral fibres, fibreglass, wood, metal, gypsum, plastic or other compositions. They are positioned within the grid opening, and are supported by the grid. The panels are either of the type that expose the grid when the ceilings are viewed from below, or conceal the grid either fully or partially, when viewed from below.
- a panel for a suspended ceiling with exposed grids normally has the form of an upper lip extending over the top of the grid with no lip on the panel below the grid. The panel hangs from the grid, by resting on this upper lip.
- Such panels are relatively simple to install, position and remove. These panels are not intended to be locked by themselves to the grid. Therefore there is a certain risk of "teething" of panels during the installation, because the panels are easily pushed out of position.
- Panels that conceal the grid from below pose special problems, since the portion of the edge underlying the grid interferes with the positioning, and removal of the panels and make the installation complicated and difficult.
- Panels that conceal the grid are in general desirable for among other benefits their appearance due to stable positioning, as well as their ability to lock the grid.
- the grid can be partially or totally concealed. Additionally, since the panels of this type conceal the metal grid, they can have a beneficial effect during fire, as they serve to insulate the metal from transferring heat, particularly where panels are of a fire retardant material.
- Panels locked to the grid which give no visual clue to their removal procedure, also provide a degree of security against unauthorized access to the space above the ceiling.
- DE 1939904 relates to panel assemblies having removable panels and particularly to suspended ceilings including parallel support runners or splines and tile panels supported on the splines, with each panel being individually selectively removable and replaceable from beneath the ceiling.
- US 3 708 941 relates to suspension systems for ceilings composed of panels or tiles, and more particularly to those systems which incorporate supporting splines engageable within edge grooves, or kurfing, of the ceiling panels or tiles.
- a ceiling panel for use in a suspended ceiling is disclosed.
- the panel is for use in a grid formed of inverted T-section beams.
- the panel has opposing active parallel edges each of which has a profile different from the other, having at least two opposing passive edges. All the edges of the panel have lower lips to conceal the grid when seen from below.
- the active parallel edges are formed with special designed kerfs which define an upper and lower lip in the edges and makes it possible to install and remove the panel from the grid without the use of tools.
- the method according to the invention makes it very easy and fast to install ceiling panels in a grid, and the panels are locked and stable in the grid.
- the set of ceiling panels in combination with the grid according to the invention are easy to install and have excellent strength.
- a method to install a suspended ceiling very fast and in a cost effective manner is provided. Furthermore, by the set of ceiling panels according to the invention a suspended ceiling with a good aesthetic look and excellent strength and durability is achieved. By use of the method and the set of panels in combination with the grid according to the invention a suspended ceiling can be installed at lower cost than already known suspended ceilings and with superior results with regard to look and durability.
- the method of installing a set of ceiling panels to a basic ceiling makes use of a supporting grid, and the set of ceiling panels includes at least three substantially rectangular panels, which have a width similar to each other.
- the sum of the length of each panel of the set of ceiling panels is defined as the total length of the set of ceiling panels.
- the panels have four edges, and each of the four edges has an upper portion defined as the part the of edge being closest to the surface facing the basic ceiling and a lower portion defined as the part of the edge being closest to the surface facing away from the basic ceiling.
- the edges are in pairs two and two parallel to each other.
- the first and the third of the edges may preferably be parallel and substantially identically shaped with a groove substantially in the middle of the edges in the longitudinal direction.
- the grooves are brought to surround one or more of the support flanges protruding from the profiles and each of the grooves may preferably have a depth substantially equal to the width of a support flange.
- the second and the fourth edge of the panel are parallel.
- the second edge may preferably be formed with a groove substantially in the middle of the edge in the longitudinal direction and the groove has a depth substantially equal to the width of a support flange of the support profile.
- Below the groove an extended protruding lip is formed in the longitudinal direction on the lower half portion of the edge.
- the lip preferably has a width sufficiently large to conceal the support profile when viewed from below, preferably substantially equal to twice the width of the support flange as said groove is brought to surround the one or more parts of the support flange.
- the first edge of the first end panel and the third edge of the second end panel are formed with a groove substantially in the middle of the edges in the longitudinal direction.
- the groove preferably has a depth substantially equal to the width of a support flange on the carrier profile.
- a protruding lip may preferably be formed in the longitudinal direction on the lower half portion of the edge.
- the lip preferably has a width substantially equal to the width of the support flange and when the groove is brought to surround the one or more parts of the support flange it preferably conceals half of the carrier profile when viewed from below.
- the edge(s) In order to make sure that the panels do not sag or bend along the first and third edges, which are not supported by the support flange of the carrier profile, it is preferred to supply one or more of these edges with a stiffening profile.
- the edge(s) In order to provide one or more of these edges with a stiffening profile the edge(s) must be formed with a groove, preferably substantially in the middle of the edge in the longitudinal direction.
- the stiffening profile may preferably be in the form an L-shaped profile, namely in the form of two flanges connected to each other in an angel of preferably about 90°.
- the stiffening profile may be in the form of a U-shaped profile, wherein the one of the flanges of the U-shaped profile fits into the groove along the edge of the panel.
- the L-shaped or U-shaped profile has a length of up to the width of the panels.
- the L-shaped or U-shaped profile has a length corresponding to between half the width of the panels up to the total width of the panels minus twice the width of the support flanges of the support profile, to thereby make it possible to apply the stiffening profile in a first or third edge of a panel without interfering with the support flange of the support profiles.
- the L-profile or U-shaped has a length which corresponds to the total width of the panels minus the twice the width of the support flanges of the support profile. Thereby the edge is reinforced in substantially all of its length.
- the L-shaped or U-shaped stiffening profiles are especially useful when the panels are large i.e. having a width above 400 mm, e.g. about 900 mm, or if the panels are thin and not sufficiently stiff themselves.
- stiffening profiles could have any shape.
- the distance between the support profiles is equal along its whole length, even when the total length of the set of ceiling panels is relatively long e.g. above 2000 mm, it is preferred to apply one or more equidistance profiles to the ceiling panels.
- the preferred number of equidistance profiles in a given set of ceiling panels largely depends on the total length of the set of ceiling panels, but in most situations it is sufficient to apply 1 or 2 equidistance profiles.
- An equidistance profile has a profile substantially as a stiffening profile as described above.
- the equidistance profile further comprises connecting flanges, snap-locks or similar means for connecting the equidistance profile to the two support profiles supporting the panel into which groove the equidistance profile is inserted.
- the connecting flanges, snap-locks or similar means for connecting the equidistance profile to the two support profiles supporting the panel into which groove the equidistance profile is inserted may in general be of any type, but preferably it should be easy to handle.
- the equidistance profile also has the same functions as the L-shaped or U-shaped stiffening profile, and, thus, there is no reason to use both an equidistance profile and a stiffening profile in the same panel edge.
- an equidistance profile is applied in the first end panel in a groove in the third edge, before further panels of the set is applied in the grid.
- the equidistance profile is secured to the support profiles to thereby secure that the distance between the two support profiles is equal along their length and is kept stable.
- the fourth edge is formed with a protruding lip in the longitudinal direction on the upper half portion of the edge.
- the protrusion has a width substantially equal to the width of the support flange.
- the set of ceiling panels are installed in the rectangle of the supporting grid so that the support flanges are concealed by the grooves or by the protruding lips on the edges of the set of ceiling panels.
- the ceiling panels are substantially shaped as quadrangles
- the carrier grid may of course be placed in any desired position with regard to the basic ceiling and have a inclination compared to horizontal direction up to 60 degrees and even up to 70 degrees, but usually it is preferred to place it in a horizontal position substantially parallel with the basic ceiling.
- the distance between the upper surface of the suspended ceiling and the basic ceiling may preferably vary from 3,5 cm to 350 cm and more preferably from 10 cm to 150 cm
- uniform panels can be used.
- the invention also relates to a set of panels in combination with a grid, wherein the set of panels includes at least three panels which preferably may be uniform.
- Each ceiling panel of the set has two identical opposing edges and two non-identical opposing edges.
- the two identical opposing edges are formed with a groove in the longitudinal direction.
- the two opposing non-identical edges are formed so that one of the edges has a protruding lip from an upper portion of the edge and the other edge has a protruding lip from the lower portion of the edge which is placed below a groove in the longitudinal direction of the edge.
- the supporting grid is obtainable by mounting two or more carrier profiles and two or more support profiles to each other.
- the two or more carrier profiles are substantially parallel to each other and the two or more support profiles are substantially parallel to each other and are substantially perpendicular to the two or more carrier profiles, to thereby provide a grid of at least one rectangle.
- a hanging clip in combination with a strap is mounted on the profiles.
- the strap can be mounted parallel with the profiles, in a way so that it is not inconvenient to install and dismount the panels.
- the invention also relates to a method of installing a suspended ceiling comprising the steps of installing one or more sets of ceiling panels to a basic ceiling.
- the method further comprise the step of install one or more secondary sets of ceiling panels, wherein each secondary set of panels includes two substantially rectangular panels having a width similar to each other, and where the sum of the length of the two panels of the secondary set of ceiling panels is defined as the total length of the set of ceiling panels, and the method comprises the following steps:
- the two secondary panels of a secondary set of profiles each has four edges with an upper portion defined as the part of the edge being closest to the surface facing the basic ceiling and a lower portion defined as the part of the edge being closest to the surface facing away from the basic ceiling, each of the secondary panels preferably comprising at least two edges each having a protruding lip in its lower portion extending substantially along the whole length of the edge, the protruding length of the respective lips in combination with the similar lips of other panels installed in the grid being adapted to the grid system so that the lips cover the grid and thereby make the grid concealed when viewed from below when the suspended ceiling is installed.
- the invention further comprises a method of installing a suspended ceiling, which method comprises the steps of installing one or more sets of ceiling panels to a basic ceiling as described above.
- the method further comprises the step of installing one or more tertiary ceiling panels wherein each tertiary panel has a width and a length, which method comprises the following steps:
- each of the tertiary panels has an upper portion defined as the part of the edge being closest to the surface facing the basic ceiling and a lower portion defined as the part of the edge being closest to the surface facing away from the basic ceiling, each of the tertiary panels comprising at least two edges each having a protruding lip in its lower portion extending substantially along the whole length of the edge, the protruding length of the respective lips in combination with the similar lips of other panels installed in the grid being adapted to the grid system so that the lips cover the grid and thereby make the grid concealed when viewed from below when the suspended ceiling is installed.
