The system further comprises a bracket (1) for holding a suspended ceiling.

A ceiling system including a carrier component and at least one removably mounted thereto. The carrier component may extend along a first longitudinal axis and may have a body portion and a plurality of support members extending from the body portion in a spaced apart manner along the first longitudinal axis. The at least one panel may be removably mounted to the carrier component by simultaneous engagement with a first support member of the plurality of support members and a second support member of the plurality of support members. At least a portion of the first and second support members may be located within a cavity of the at least one panel when the at least one panel is mounted to the carrier component.

A ceiling panel having a connection portion at one of end portions on both sides in a first direction of a panel body in a shape of a rectangular flat plate, the connection portion connecting with a connected portion of an adjacent ceiling panel. The connection portion is fixed to the end portion by a fastener, the fastener being fastened to an insertion part inserted into a layer of the panel body from a cut portion opening on a back face of the end portion so as to penetrate a securing part provided along the back face of the end portion.

The system includes a plurality of panels made of a thermoplastic material. The panels have a hermetically-sealed connection between them using a plurality of first thermoplastic welded junctions. The system further includes a plurality of elongated snap-in panel anchoring units. Each unit including complementary first and second members to be latched together through an interfering engagement. At least the first member of each snap-in panel anchoring unit is made of a thermoplastic material and these first members are attached to the outboard major surface of the panels using a plurality of second thermoplastic welded junctions.

A ceiling panel to be fixed to a ceiling base, the ceiling base having a long shape extending in a first direction and being provided in parallel spaced in a second direction orthogonal to the first direction. The ceiling panel includes a panel body in a shape of a rectangular flat plate, a magnet provided on a back face side of both end portions of the panel body in the second direction and being attracted to an attracted portion of the ceiling base, a hooked portion provided for a first end portion of the panel body in the first direction, and a hooking portion provided for a second end portion of the panel body in the first direction, the hooking portion hooking on a hooked portion of an adjacent ceiling panel to be provided in the first direction.

A ceiling system which includes a substrate and securing members configured to engage a grid system to mount the substrate to the grid system. The securing members may include a mounting flange positioned with its bottom surface adjacent to the substrate. The mounting flange may be coupled to the substrate via fasteners. The securing members may further include a positioning member protruding from a top surface of the mounting flange and terminating in a distal edge. The positioning member may have a first side edge and a second side edge. The securing members may include a grid engagement member extending from the distal edge of the positioning member. The grid engagement member may be located centrally between the first and second side edges of the positioning member. The grid engagement member may have a U-shaped engagement portion configured to engage a grid member of the grid system.

A formulation for an acoustically transparent coating for use on an acoustical substrate comprising a water dispersible binder and relatively large filler particles, and characterized by a high pigment to volume concentration, high viscosity, high shear thinning, and fast drying to enable the formulation to be sprayed in droplets that retain their identity when in mutual contact and in a dry coating can be efficiently sanded flat.

Disclosed is a suspended ceiling system, a securing member, and process of installing a patterned suspended ceiling system. The suspended ceiling system includes a grid system having first members and second members, and at least one substrate which extends below the grid system. The at least one substrate has an exposed surface and a concealed surface, and the at least one substrate has first sides and second sides which extend between the exposed surface and the concealed surface. Securing members attach to the concealed surface proximate the first sides, and the securing members have grid engagement members which secure the at least one substrate to the grid system. The securing members cooperate with the first members and the second members of the grid system to properly position the substrate and the spacing between adjacent at least one substrates is controlled.

An anchor bolt assembly according to an embodiment of the present disclosure includes an anchor body provided with a plurality of pointed protrusions on an upper surface thereof, an anchor shell provided with open upper and lower sides thereof, extrapolated to a lower side of the anchor body, provided with a first incised part having a Y shape at an equal interval along a circumference of the anchor shell, and provided with a second incised part having a v shape at an equal interval along a longitudinal direction of the first incised part, a tightening member screwed to the anchor body through a screw thread provided on an inner circumferential surface of the tightening member, and provided with a processing part for increasing frictional force along an upper circumference of the tightening member.
