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.

Disclosed is a ceiling panel support assembly, including at least one support structure configured to provide at least one panel receiving region adjacent thereto, and at least one support hub structure to be centrally positioned in the at least one panel receiving region. The at least one support structure and the at least one support hub structure may be configured to support a plurality of panels therebetween, with at least a subset of the plurality of panels oriented in side-by-side relation along a circumferential region of the at least one support hub structure and extending outwardly therefrom.

A structure-lining apparatus comprising a plurality of transversely and longitudinally extending panels connectable to a structure and connectable edge-to-edge via complementary connector components on their longitudinally extending edges. Each panel comprises transversely extending edges generally orthogonal to their longitudinally extending edges. Each panel comprises first and second complementary connector components on first and second longitudinally extending edges thereof. The apparatus comprises at least one edge-to-edge connection between a first connector component of a first panel and a second connector component of a second panel wherein a primary male connector component of the second connector component of the second panel is extended into a primary female connector component of the first connector component of the first panel and a secondary male connector component of the first connector component of the first panel is extended into a secondary female connector component of the second connector component of the second panel.

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.

A ceiling panel of which both end portions in a second direction are held on a ceiling base having a long shape extending in a first direction and being provided in parallel spaced in a second direction the ceiling panel includes a panel body, a hooked portion, and a hooking portion. The hooking portion has a folded part formed by being bent into a room side from a tip end portion in an extending direction of an extension portion extending outward in the first direction from the second end portion in the first direction, and by being further folded inward in the first direction, and the hooked portion keeps hooking and holding of the folded part with a second end portion in the first direction of an adjacent ceiling panel to be provided in the first direction being positioned upward further than the first end portion 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.
