The wall body has two types of single-layer and double-layer glass, and the curtain wall is an attractive and novel building wall body decoration method and is a remarkable characteristic of modern meaning high-rise building times. The curtain wall mainly comprises a panel and a support frame, wherein the support frame plays a role in connecting the panel, and the support frames used by different curtain walls are different. When the curtain wall is installed, the support frame needs to be fixed on a building firstly, and then the panel is installed on the support frame.
However, the curtain wall support frame in the prior art has the following disadvantages in application: (1) the curtain wall support frame in the prior art mostly adopts steel (steel pipes or steel plates and the like) as a structural base body, however, the impact resistance and the vibration damping buffering performance of the steel in the prior art are not ideal, and the integral impact resistance and the vibration damping buffering performance of the support frame cannot meet the high requirements of modern people on buildings when the steel is applied to the curtain wall support frame. (2) When using under abominable complex environment, the curtain support frame can take place expend with heat and contract with cold because of the drastic change of temperature, leads to the support frame to appear the condition of tiny gap line after using for a long time easily, produces the potential safety hazard to lead to the emergence of incident. (3) The curtain support frame among the prior art mostly only possesses the connection fixed effect, and when the curtain received wind-blowing, the impact force that the wind pressure brought had applied the junction of supporting frame structure completely, and no buffering unloads the power structure, influences the stability of support frame.
