Abstract

A ceiling system in one embodiment includes a grid support member including a flange defining a bottom surface and a ceiling panel supported by the grid support member. A first facing sheet includes a peripheral edge portion attached to the grid support member. An integral cutting guide groove is formed in the bottom surface of the grid support member. The peripheral edge portion of first facing sheet includes an edge which is axially aligned with the groove. A second ceiling panel includes a second facing sheet including a peripheral edge portion having an edge axially aligned with the groove and disposed adjacent the edge of the first facing sheet to form a seam. The first and second facing sheets conceal the grid support member. A related method of installation is disclosed.

First claim

1 - 25 . (canceled)

26 . A ceiling system comprising:
a longitudinally extending grid support member including a longitudinal axis, a flat horizontal bottom flange defining a bottom surface, an opposing top surface parallel to the bottom surface and having a vertical thickness defined between the surfaces, and a vertical web extending upwards from the flange; the vertical web comprising a unitary monolithic structure; the bottom flange lying in a single horizontal plane and comprising a unitary monolithic structure which extends horizontally continuously in a transverse direction from a first longitudinal edge to an opposing second longitudinal edge; a ceiling panel supported by the grid support member; a first facing sheet attached to a bottom surface of the ceiling panel and having a peripheral edge portion attached to the grid support member; and an integral cutting guide groove formed in the bottom surface of the grid support member, the groove extending linearly along the longitudinal axis and having a depth penetrating the bottom flange less than the thickness of the bottom flange; wherein the peripheral edge portion of first facing sheet includes an edge which is axially aligned with the groove.

27 . The ceiling system according to claim 26 , wherein the first facing sheet is adhesively coupled to the grid support member.

28 . The ceiling system according to claim 27 , further comprising double-sided adhesive strips which adhesively couple the first facing sheet to the grid support member.

29 . The ceiling system according to claim 26 , wherein the ceiling panel has a honeycomb core structure.

30 . (canceled)

31 . The ceiling system according to claim 26 , wherein the first facing sheet is attached to a spacer panel disposed between the bottom surface of the ceiling panel and the first facing sheet.

32 . The ceiling system according to claim 31 , wherein the spacer panel has a bottom surface located substantially flush with the bottom surface of the grid support member.

33 . The ceiling system according to claim 26 , wherein the grid support member is T-shaped.

34 . The ceiling system according to claim 26 , wherein the ceiling panel is a tegular panel having a stepped side edge profile.

35 . The ceiling system according to claim 26 , further comprising a second facing sheet of a second ceiling panel supported by the grid support member, the second facing sheet having an edge which is axially aligned with the groove and disposed adjacent the edge of the first facing sheet.

36 . A ceiling system comprising:
a first grid support member and second grid support member spaced apart from the first grid support member; each of the first and second grid support members including a longitudinal axis, a flat horizontal bottom flange defining a bottom surface, an opposing top surface parallel to the bottom surface and having a vertical thickness defined between the surfaces, a vertical web extending upwards from the bottom flange, and an integral cutting guide groove formed in the bottom surface and extending linearly along the longitudinal axis, the groove having a depth penetrating the bottom flange less than the thickness of the bottom flange; the vertical web comprising a unitary monolithic structure; the bottom flange lying in a single horizontal plane and comprising a unitary monolithic structure which extends horizontally continuously in a transverse direction from a first longitudinal edge to an opposing second longitudinal edge; a ceiling panel extending between the first and second grid support members, the ceiling panel supported by the first and second grid support members; and a first facing sheet attached to a bottom surface of the ceiling panel and attached to the first and second grid support members; wherein the first facing sheet includes a first edge which is axially aligned with the groove of the first grid support member and an opposing second edge which is axially aligned with the groove of the second grid support member.

37 . The ceiling system according to claim 36 , further comprising a second facing sheet having an edge axially aligned with the groove of the first grid support member and disposed adjacent to the first edge of the first facing sheet.

38 . The ceiling system according to claim 36 , wherein the first facing sheet is adhesively coupled to the grid support member.

39 . The ceiling system according to claim 38 , further comprising double-sided adhesive strips which adhesively couple the first facing sheet to the grid support member.

40 . The ceiling system according to claim 36 , wherein the ceiling panel has a honeycomb core structure.

41 . (canceled)

42 . The ceiling system according to claim 41 , wherein the first facing sheet is attached to a spacer panel disposed between a bottom surface of the ceiling panel and the first facing sheet.

43 . The ceiling system according to claim 36 , wherein the grid support member is T-shaped.

44 . The ceiling system according to claim 36 , wherein the ceiling panel is a tegular panel having a stepped side edge profile.

45 . A ceiling system comprising:
a first grid support member and second grid support member spaced apart from the first grid support member; each of the first and second grid support members including a longitudinal axis, a flat horizontal bottom flange defining a bottom surface, an opposing top surface parallel to the bottom surface and having a vertical thickness defined between the surfaces, a vertical web extending upwards from the bottom flange, and an integral cutting guide groove formed in the bottom surface and extending linearly along the longitudinal axis; the vertical web comprising a unitary monolithic structure the bottom flange lying in a single horizontal plane and comprising a single unitary monolithic structure which extends horizontally continuously in a direction transverse from a first longitudinal edge to an opposing second longitudinal edge; a ceiling panel extending between the first and second grid support members, the ceiling panel comprising a honeycomb core and supported by the first and second grid support members; and a bottom facing sheet attached to a bottom of the honeycomb core of the ceiling panel and further directly attached to the bottom surfaces of the first and second grid support members; wherein the bottom facing sheet includes a first edge which is axially aligned with the groove of the first grid support member and an opposing second edge which is axially aligned with the groove of the second grid support member; and wherein the bottom facing sheet is in a vertical position that is substantially flush with the bottom surfaces of the bottom flanges of the grid support members.
