Description of the invention (ί) The present invention relates to a ceiling panel of the form defined in the introduction of the first scope of the patent application. In particular, U.S. Patent Nos. 3,462,906 and 4,223,503, and U.S. Patent No. 1,249,765 both disclose this style of ceiling inserts. 'They are arranged side by side and form an interconnecting system at the top of a space. Underside cover. These individual panels are made of a metal material that has been folded or rolled. Typically, the bottom cover is supported by a support structure in the form of a system that supports the sliver, which is mounted on the wall defining the space. The underside cover may also be provided with a suitable thermal and / or vibration insulation device, such as an insulation pad placed on the surface of the panel facing the ceiling. A common feature of the conventional ceiling panels that form the basis of the present invention is that they are all self-supporting, and they can be interconnected by complementary and vibrationally deformed meshing regions arranged along the longitudinal edge side of the panel. . When the panels form a self-supporting and interconnected system, the weight of each panel itself can also be partially transmitted to the supporting structure via adjacent panels. Once the engaging area is extended by the total length of the longitudinal edge side of the panel, it can especially ensure the tightness necessary for the bottom surface to prevent the penetration of flames and the passage of smoke or other gases, for example: they can be from Burning objects in the space covered by the bottom surface are discharged. But when there is such a need, it is often difficult to remove one or more ceiling panels from the conventional underlay without damaging adjacent ceiling panels, or screws or similar fasteners must be removed. In the case where many ceiling panels must be removed like this, it may be between, for example, the ceiling panel and the bottom cover 3 ----- Γ C, please read the precautions on the back before filling this page) -V6

Description of the invention In the construction of ceiling panels, it is inevitable that static impact may be caused on the panel, such as the weight of the panel itself and the weight of the insulation pads pressed on it, if any, which also promotes Ribs or similar must be used to strengthen the panel. In addition, it is necessary to be able to deal with special conditions related to fires that occur in the space below the bottom cover. In addition, for the case where the panel must be structurally assembled to prevent flames and smoke from penetrating in the meshing area as described above, the stability and integrity of its underside coverage must also be constructed to be capable of increasing temperature. For a long time. The strength of the locking engagement required between the flange portions during a fire load is also known, because this locking engagement must not only ensure continuous tightness, but also that it comes from its own weight and insulation material (if (If any) the force can be transferred from a ceiling panel to its adjoining panel, and even to the supporting structure covered by the supporting bottom surface. However, in view of the aforementioned known undercover, it has been difficult to comply with the relevant requirements of the present law for a period when the undercover has been in a tight state. The object of the present invention is to provide a ceiling panel which is improved and which in particular achieves at the same time the advantageous properties described below:-the engagement region allows the transmission of force from one ceiling panel to the next:-between the panels The joints are very tight in use; • Each single panel can be removed or reinstalled without having to remove one or more __4 ----,-I ------- install --- ----- Order --------- line (please read the precautions on the back before writing this page) The Intellectual Property Bureau of the Ministry of Economic Affairs, the consumer cooperation of Du Du printed this paper, the national standard (CNS) ) A4 size (210 X 297 meals) Λ7 B7 4267 8 V. Description of the invention ()) Other panels;-The load bearing capacity and integrity of the bottom surface can be maintained for a considerable time under high temperature conditions; the above is This is achieved based on the features of the present invention, such as the first part of the scope of patent application. When the first and second flange portions each exhibit an inclined first portion, the amazing effect of the previously described design can be found. In a fire, the entire flange portion will therefore deflect downwards to the web portion of the ceiling panel. This provides a very reliable fit of the joint, so that at least the complementary meshing area of the adjacent web portion will remain in very close contact with each other. Furthermore, according to the present invention, it is also possible to release the locking engagement by touching the designated panel under a normal upward pressure shock, for example, to cause an elastic deformation of the flange portion, Therefore, the locking engagement of a longitudinal side edge can be loosened. As described in item 2 of the scope of the patent application, when the flange portion forms a locking section with a free edge extending at a maximum distance from the web portion of the panel and extending along the edge side, two An improved interlocking of two adjacent ceiling panels is achieved in order to improve the stability of the locking section when it may be damaged by the impact of a fire, that is, the locking section will be The compressive stress caused by this area is the largest at the farthest part from the web part and warps and deforms. It has been found from experiments that this folding action combined with the downward bending of the entire flange portion previously described will have the effect of preventing the adjacent ceiling panel from coming loose from the locking engagement in a fire; compared to the general Condition * This situation itself proves that the 5 sheets are in compliance with the Chinese National Standard (CNS> A4 specification (210 X 297 mm) ----; --- 1 ------ pack ----- .----- Order --------- line (please read the precautions on the back before writing this page > Printed by the staff of the Intellectual Property Bureau of the Ministry of Economic Affairs, printed by the cooperative 42678 1 'A7 B7 V.

Description of the invention (s) Bottom. The web part 5 constituting the visible part of the ceiling panel in this space is preferably flat, but may optionally have a slight curvature as required. However, it is certain that the web portion 5 is a plane defined as an imaginary main range of the ceiling panel, that is, a plane substantially parallel to the ceiling. Preferably, the ceiling panel 1 has a rectangular basic shape including a longitudinal central region M, and the web portion 5 has longitudinal edges 8 and 9 and a lateral edge. The arrangement of the flange portions 20 and 40 extends along the entire length of the panel 1 along each of the longitudinal edges 8 and 9. Preferably, the ceiling panel shown is made of a flat sheet metal work piece, and the flange portions 20 and 40 are made by folding or the like. The complementary engagement areas of the flange portions 20 and 40 allow two identical ceiling panels 1 to be connected to each other. In the first figure, the reference numerals for the engaging areas 21 and 41 are generally assigned, and thus include individual panel parts extending longitudinally at the ceiling panel at different relative angles. More specifically, each of the engagement regions 21 and 41 is roughly constituted by an S-shape inclined with respect to a longitudinal plane Η. The plane Η extends perpendicular to the plane of the main range of the ceiling panel 1 and the angle defined hereinafter is measured from a plane relative to a plane of the main range of the ceiling panel 1 which is parallel to the plane Η Be calculated. Preferably, as shown in the figure, the meshing area 41 includes a first portion 42 extending upward and away from the web portion 5 at an angle α of about 12 ° with respect to the plane Η.

Description of the invention (B) The second part is combined. The second portion extends at a β angle, preferably approximately 25 °, and extends in a direction opposite to the web portion 5; and, the second portion may be bent or The compression portion 45 merges with a third portion 46. The third part extends in a manner similar to a / 3 angle of about 12 ° upwards and away from the central region M. A further bending action allows the third portion 46 to merge with a fourth portion 48; the fourth portion will form an angle of (preferably) about 79 ° with respect to the plane Η. Before the fourth part 48 reaches an imaginary extension part of the second part 42, the fourth part 48 can be merged with the fifth part 50 by a bending action. The fifth portion extends at an r angle of about 12 ° and upwards and away from the web portion 5. It can thus be ascertained that the first, third, and fifth portions extend substantially parallel to each other, and that they have approximately the same inclination angle with respect to the plane Η. And in the case of fire, this results in excellent control deformation. In the following, this fifth part 50 will be called " locking section ". In the application of the meshing area 21, it also similarly includes a first portion 22 merged into the second portion 24; after that, the second portion is combined with an end portion 28 to form a nose 25 And, the diameter of the entire part is roughly corresponding to the diameter of the opposite part of the meshing area 41. However, preferably, the angle X with respect to the plane Η is larger than the angle X ', and the angle y' is larger than the angle y. Therefore, when the nose portion 25 is inserted into the compression portion 45, a clamping force can be provided when the two ceiling panels are combined. The previously mentioned end portion can optionally form a bent portion that merges into an extension portion 29 facing the rear side, and the extension portion can grant the portion 26 8 This paper size is in accordance with Chinese standards (CNS ) A4 size (210 X 297 mm) ----.-- Ί I ------ install -------- order --------- line (please read the back first (Notes on this page, please fill in this page) y ά2β7 8 1 Α7 Β7 Printed by the staff of the Intellectual Property Bureau of the Ministry of Economic Affairs and printed by the cooperative V.

From the first picture, it can be confirmed that the relative The angles α ′ and α of the meshing region 41 and angles α ′ 3 and Θ of the 6 »angle can also be applied to the meshing region 21. The second figure shows two by arranging the meshing region 21 ′ into the meshing region 41 in a side-by-side arrangement. The combined ceiling panel 1 and Γ, that is, the nose head 25 is inserted into the compression portion 45. As mentioned before, the shape of the engaging regions 21 and 41 preferably, but not necessarily, develops this insertion effect into the The clamping action of the meshing region 21 ', especially an meshing region that is deformed during insertion. It can be understood that the shape of the insertion region In particular, in order to provide a suspended state of the ceiling panel 1 ′ and the ceiling panel 1, vertical forces such as the weight of the panel itself are allowed to pass through the connection portion without being transmitted. In the use of ceiling panels, a plurality of side-by-side ceiling panels 1 are installed at a certain distance below the ceiling, as shown in the second figure. Before installation, a fixed A support structure such as a support bar is present on the wall. The support structure is used to support and hold the lateral edges of the lateral edge of the ceiling panel 1 and the longitudinal sides of the outermost ceiling panel covered by the bottom surface, so that each The ceiling panel can be extended between two support bars to present a self-supporting unit. In applications such as underfloor covering on a cabin, the ceiling panel typically has an equivalent space between two wall surfaces of the cabin Distance of about 3 meters and its width is about 0.3 meters, and the height of the engaging area 21 is about 23 mm and the bite The height of area 41 is about 25 mm.

Description of the Invention u) One of the 45 new nose panels 25 and one side by side are arranged side by side. It can be seen in particular from the second figure that the individual ceiling panels can be easily disassembled from each other by applying upward pressure along the left edge 8 of the ceiling panel, so that when the end portion 28 is pressed When the fourth part 48 does not interfere, the nose 25 can be removed from the compression part 45. Then, by rotating the ceiling panel ’, it can be removed from the adjacent ceiling panel and removed. In order to comply with possible regulations today and in the future regarding the limitation of damage caused by fire, the undercover must be manufactured to prevent the penetration of flames and smoke from the space below, and as long as the temperature of the space continues to rise for a long period of time On the occasion, it is possible to prevent the ceiling panel panel from sinking. From the fire test, it was found that when the bottom surface is in danger of actually collapsing, the present invention clearly provides a longer time before the danger occurs. When a bottom cover composed of several ceiling panels suspended in accordance with the present invention as described above is exposed to fire, the bottom cover will present a single or double curved surface due to the linear expansion of the material. The third figure shows in a slightly exaggerated manner how the flange portion 40 and the flange portion 20 (not shown) connected to the 'flange portion are deformed in a fire; it can be seen that How the flange portion is inclined, and how the special S-shape of the engagement region causes the entire connection portion to bend downward during a fire load. It can be confirmed that during this deformation, a stronger clamping force will be generated at the joint at the same time, and thus become tighter. During this deformation, the typical situation of insufficient stability occurs in the section of the ceiling panel where the maximum compression stress is generated, that is, in particular-'IT — — II — --- I — I Order · -----— — (Please read the precautions on the back before filling in this page) This paper size is applicable _ National Standard (CNS) A 彳 Specifications (2) 〇X 297 mm 4267 8 1 at ______ __. ^ _ B7 V. The description of the invention (f) is in the locking section 50, so that it will present a bulging shape with creases in the longitudinal direction of the sectional view of the ceiling panel, as shown in the fourth figure As shown. It is known that 'this deformation provides a loosening between the flange portions 20 and 40 which can prevent the engagement, and thus prevents dispersion at the joint. On the one hand, the structure of the described flange portion provides a protection against dispersed forces at the joints between the panels in the event of a fire, and thus prevents the disappearance of the integrity of the cover and the collapse of the cover On the other hand, it can prevent the increased danger due to the disappearance of the tightness required by the flame and the exhaust pipe gas. The fifth figure shows an edge panel covered by a supporting device for the ceiling panel according to the present invention to form the underside cover. Preferably, the contour of the edge forms a ceiling panel according to one and a half of the present invention, wherein the contour of the edge exactly comprises an S-shape for connecting with the adjacent ceiling panel, which can provide the edge panel The opposite longitudinal edge of the plate has a bend so that the longitudinal edge can be connected to the locking elongated strip extending from the support structure in a particularly convenient manner. ------- 1 ------- installation .--.----- order ------- line (please read the back of the page first; i will write this page) Consumption cooperation between employees of the Intellectual Property Bureau of the Ministry of Economic Affairs Du printed paper sizes Applicable national standards &CN; A4 specifications (210 X 297 mm)
