S5, waterproofing treatment: scraping and smearing silicone weather-resistant structural adhesive at the hinge joint between the first folded plate 21 and the aluminum veneer 1, the first through groove 211 and the hinge joint between the second folded plate 22 and the connecting plate 41 in sequence, then filling a foam rod in a gap between the upper and lower adjacent aluminum veneers 1, and then injecting sealing structural adhesive.

The implementation principle of the embodiment of the application is as follows: firstly, the position of the inserting plate 42 is locked by the matching of the limiting block 53 and the limiting groove 421, so that the aluminum single plate 1 and the framework are quickly installed and fixed, and the danger coefficient is effectively reduced.

Secondly, by arranging the elastic telescopic expansion piece 2, when the aluminum single plate 1 receives positive and negative wind pressure and vibrates along the direction close to the outer wall or along the direction far away from the outer wall, each folded plate on the expansion piece 2 deflects and avoids, and the torsion spring accumulates elastic potential energy to buffer and absorb the vibration force borne by the aluminum single plate 1, so that the phenomenon that the vibration of the aluminum single plate 1 is directly transmitted to the inserting plate 42 to cause falling is reduced; and through the cooperation of extensible member 2 and rubber band 3, rubber band 3 has certain elasticity, therefore when the deflection of first folded plate 21 and second folded plate 22 was dodged in order to force rubber band 3 to take place the elastic bending deformation, the interference of rubber band 3 can restrict the displacement deflection of first folded plate 21 and second folded plate 22 to effectively cushion the energy-absorbing to the vibrations of aluminium veneer 1.

Thirdly, when 1 vibrations of aluminium veneer and small amplitude displacement, the deformation skew takes place for extensible member 2 and rubber tape 3, and the sectional area that holds the chamber changes, meets water inflation rubber strip 35 and utilizes self deformation in order to restrict the sectional area trend of changing that holds the chamber to the buffering absorbs the vibrations energy.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
