Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ceiling structure formed by a number of panels supported by a support member, such as a ceiling structure for a ship's accommodation facility, and in particular, to a ceiling structure formed by a number of panels supported by a support member, and in particular to a ceiling structure for a ship's accommodation facility. The present invention relates to a ceiling panel comprising a laminate having upright edges, between which edges a mineral wool thermal insulation side is laid, the flange comprising a portion for engaging a flange of an adjacent panel.

This type of ceiling panel is not typically used for suspended ceilings;
The first purpose is to hide the supporting structure, and the second purpose is to protect the structure from the heat in the event of a fire caused by the containment facilities below the cypress structure. Known panels have unsatisfactory impermeability to high flames and smoke passing through the joints between the panels, and the mutual support of the connecting elements is not sufficient, causing distortion in the tendon. This distortion can result in dangerous gaps between the panels at the joint side 7yrK.

It is an object of the present invention to separate panels in visible ceiling structures.
112 can be removed, and the above-mentioned disadvantages can be eliminated.

The panel according to the invention has a structure in which the free end of the flange is directed downwards a
ll, the flanges being bent inwardly on one side and outwardly on the other side, and a protrusion approximately in the center of one of the flanges; , and is characterized by the presence of corresponding recesses in the other flanges.

The part of the free edge of the flange engages the corresponding part of the ceiling panel adjacent to it, and also the engagement of the protrusion in the groove of the flange at each joint between the panels is effected thereby. This provides an interconnection of the joints and ensures that any displacement of the panel 11 at the level of the ceiling is stopped. The part forms a labyrinth, thereby preventing the penetration of smoke and hot gas 2. Ceilings made of thin steel sheets and having panels provide a high degree of safety in case of fire.

According to the invention, the width of the curvature of the inwardly bent portion is preferably such that it fits tightly into the vortex of the outwardly bent portion of the adjacent panel. This embodiment provides increased impermeability to gases from a fire and enhances the effectiveness of the connection between adjacent members without generally requiring complex assembly or disassembly.

To further increase the resistance to ignition on the other side of the ceiling in case of a fire, the free end of the curved section is located below the upper surface of the insulation. Mineral wool dissipates possible eruptions of hot gases entering through the joints between the panels, thus preventing or reducing damage in the space above the ceiling panels.

According to the invention, the protrusions can be separated and generally circular studs are spaced apart. This embodiment facilitates the disassembly of the parts if a panel has to be removed in the middle of the ceiling. The tensioning effect of the protrusion can be released by inserting a piece of sheet metal at the joining point of the curve of the panel and between the two studs, the thickness of which corresponds to the height of the stud. be done.

The invention will be explained in more detail below with respect to embodiments shown in the drawings.

The ceiling panel 1 is supported by a support member 9 of a wall 8, for example 0
．． A thin steel plate 2 having a thickness of 7 to 1.0 mm and an upper layer made of mineral wool to provide thermal insulation and reduce the conduction of sound or noise from structures above the ceiling. It will be done. Standing upright on the 4u11 side of Usukagane 2II Shiju) 5~
No. 53, the drawer is provided with curved portions 4 and 5 on the free edge. Portion 4 is bent outwardly, forming a downwardly directed groove, while N1 portion 5 is bent inwardly, also forming a somewhat narrower downwardly directed groove. The section has two purposes, firstly to form a connection between two adjacent panels in the ceiling and secondly to the extent that the panels are preferably self-supporting from wall to wall in the accommodation facility. This is to increase the vertical inertia t-mayl of the panel 1. If the distance between the shields is too large, the portion can still serve as a fixation point for a hanging chest anchored in the structure above the ceiling.

In order to increase the connecting force between adjacent elements, one of the upright flanges has a notch 6 extending in the longitudinal direction of the upright flange approximately in the middle of its width. On the other flange a projection 7 is arranged corresponding to the recess 6 in the adjacent panel. When two panels are placed in close relationship, 1
It is difficult to move one panel vertically with respect to another panel. This ensures that the ceiling made of panels forms a level surface and also provides interstiffening of the panels, allowing for an increase in the span between the keys 8.

The interlocking effect disappears when the panels corner each other. It is not a problem to build up the ceiling from one end using separate springs 1. It is preferable that the projections 7 are not continuous but are arranged with gaps. 1141:,
, h is more useful than a circular shape. This embodiment makes the removal of the panel in the center of the ceiling #; The joining of two panels is done by inserting them into the nil section, thereby reducing the vertical displacement of the panels.
It is a "Wl" thing.

The thickness of the layer of mineral wool is preferably such that the top of the insulation is lower than the free edge of the green bent part of the flange. Hot gases from a possible fire that permeate through the gaps P'91 between the panels are diffused into the mineral wool, reducing the risk of fire in the space between the ceilings. Furthermore, the joining points between the panels form a labyrinth to prevent the penetration of warm gases or smoke.

The impermeability to smoke is further advantageous with regard to thermal and sound insulation.
