[0029] Example 1

[0030] As Figure 1 , Figure 2 and Figure 4 indicate, the utility model with a decorative explosion vent wall comprises an inner cement board 1, a keel frame 3 and an outer cement board 6.

The specific thickness of the color-coated sheet is relatively thin, and the strength is low, which does not affect the fragmentation of the outer cement board 6 when the explosion occurs, and can also play a decorative and protective role.

[0034] Embodiment 2

[0035] If the outer cement board 6 also adopts the traditional fastening wire or blind core rivet connection, more fastener ends will be left on the outer facade, which affects the integrity of the outer facade and is not beautiful.

The top plate 402 of the aluminium hanging piece 4 is embedded into the lower groove 602, and the lower part of the top plate 402 is embedded into the upper notch 603. A sealing assembly 7 is arranged between the bottom surface of the shielding edge 604 and the upper notch 603.

[0039] Specifically, as shown in Figures 1 to 3 The top surface of the base plate of the aluminium hanging piece 4 is provided with a limiting wing plate 404 on both sides, and the limiting wing plate 404 limits the inner side wall of the outer cement board 6.
