Analysis of the problem of the failure mode of the stone of the honeycomb aluminum plate.

1.Overall instability: stoneHoneycomb aluminum plateNot enough bending stiffness.

Honeycomb aluminum plate shear wrinkle: the honeycomb shear modulus is too small, the adhesive shear strength is too low, resulting in the final failure after deflection.

2.Surface wrinkling: the adhesive plane tensile strength is not enough to cause the surface plate to protrude outward, aluminum honeycomb compression strength is not enough to cause the surface plate to sink inward.

3.Instability of aluminum plate between holes of honeycomb aluminum plate(wrinkling)The stone table board between the honeycomb holes is broken: the table board is too thin and the honeycomb holes are too large.

4.Panel rupture: the thickness of the whole plate is not enough, the thickness of the panel is not enough, and the strength of the panel is not enough.

5.Honeycomb shear failure: honeycomb shear strength is not enough, the whole plate thickness is not enough.

6.Honeycomb deflection collapse: the honeycomb plane compression strength is not enough, the deflection is too large.

7.Local pressure loss of honeycomb: honeycomb compression strength is too small.

8.Table board and honeycomb separation: table board and honeycomb peel strength is not enough.

根据以上所述，石材Honeycomb Panel及石材Honeycomb Panel幕墙工程的如下指标要符合要求：①The bending stiffness, bending strength and shear strength of the whole plate.②Aluminum honeycomb shear strength, compression strength.③Thickness and strength of the plate.④Shear strength and peel strength between sheet and aluminum honeycomb.

Therefore, three aspects of technical design are involved:

1When the honeycomb aluminum plate is developed as a new building material variety, all the above indicators are designed.

2When the standard stone honeycomb aluminum plate of the manufacturer is selected for the construction curtain wall project, some important indicators are allowed to be designed.③When non-standard panels are used in the construction curtain wall project, some or all indicators should be designed according to the actual project.
