The height of the folded edges is set to be larger than the thickness of the honeycomb plate main body, and the sum of the height of the folded edges and the height of the highest part of the groove bottoms of the accommodating grooves is smaller than the thickness of two honeycomb plate main bodies, so that the height setting space of the folded edges is relatively larger, the folded edges can be set to be relatively higher, the size range of the adaptive triangular keels is wider, and the folded edges of two adjacent staggered buckled frameless honeycomb plates are allowed to be mutually inserted into the accommodating grooves to be flatly stacked, so that the beneficial effects of being convenient for packaging and storage and transportation and being beneficial to the installation and use of the frameless honeycomb plates are achieved, the technical problem that the size and the shape of the triangular keels used for being matched and connected with the folded edges are limited due to the fact that the folded edges are set to be lower than the honeycomb plate main bodies in the transportation and packaging requirements is solved, and the use of the frameless honeycomb plates is affected.

In addition, since the height of the folded edge is limited by the relatively small thickness of the honeycomb panel body, the thickness of the honeycomb panel body can be set to be relatively small, for example, the thickness of the honeycomb panel body can be 8mm, so that the cost is saved.

In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.

As shown in fig. 1 and 2, in one or more embodiments of the present application, there is provided a frameless honeycomb panel including a honeycomb panel body 100 and a flange 200 enclosed at an outer periphery of the honeycomb panel body 100, and the flange 200 is formed by bending at least part of the honeycomb panel body 100.

4. A frameless honeycomb panel according to claim 3 wherein the third fold, the fifth fold, the resilient snap heads are bonded to the inner surface of the panel by a third adhesive layer, and the resilient snap heads are bonded to the third fold by a fourth adhesive layer.

5. A frameless honeycomb panel as defined in claim 1, wherein said flange has spaced on its inner surface an insertion flange for insertion into a triangular keel and preventing removal of said flange and a stop flange for preventing transition insertion of said flange into said triangular keel, said insertion flange being located above said stop flange.

6. The frameless honeycomb panel of claim 5, wherein the insertion flange includes a guide surface for guiding the flange to be inserted into the triangular keel and a release preventing surface for preventing the flange from being withdrawn from the triangular keel, one end of the guide surface being connected to the flange, the other end being connected to one end of the release preventing surface, the other end of the release preventing surface being connected to the flange;

The guide surface faces to the insertion direction of the folded edge into the triangular keel, and the anti-falling surface faces to the withdrawal direction of the folded edge from the triangular keel;

The guide surface and the anti-falling surface are inclined surfaces, and the included angle between the guide surface and the insertion direction is smaller than 45 degrees, so that an inclined surface which is inclined downwards is formed, and the guide surface and the anti-falling surface are conveniently and gradually inserted into the triangular keel; the included angle between the anti-falling surface and the withdrawing direction is larger than 45 degrees, so that an inclined surface which inclines upwards is formed, and the difficulty of withdrawing the folded edge from the triangular keel is improved.

7. The frameless honeycomb panel of claim 5, wherein the limit flange comprises a limit surface for abutting the triangular keel, the limit surface faces the insertion direction of the flange into the triangular keel, the limit surface is an inclined surface, and an included angle between the limit surface and the insertion direction is greater than 45 degrees to abut the triangular keel upwards.

8. A frameless honeycomb panel as defined in claim 7, wherein said flaps are cut at four corners to form locating edges, said locating edges being flush with said stop surfaces to prevent said flaps from being inserted into said triangular keels in transition.

9. A frameless honeycomb panel according to any one of claims 1 to 8, wherein the frameless honeycomb panel is suspended from a main runner by a triangular runner, the main runner being secured to a ceiling;

The frameless honeycomb plate is further provided with an anti-tripping device for preventing falling, one end of the anti-tripping device is used for being connected with the folded edge, and the other end of the anti-tripping device is used for being connected with the triangular keel, the main keel or the ceiling.

10. A suspended ceiling, comprising at least two frameless honeycomb panels according to claim 9, wherein the insertion flanges on the folded edges of two adjacent aligned and folded frameless honeycomb panels are spliced into an arrow-shaped plug, the plug is blocked in the triangular keel, and the bottom surface of the triangular keel is abutted against the limit flange and the positioning edge.
