摘　　要：当前,幕墙结构已被广泛应用,但板材在遭遇温度波动和结构变形的情况下,可能出现位移,从而导致接缝处于不同的应力状态。因此,为了确保接缝的牢固性,必须选择一种既可以抵抗位移又可以维护良好黏合性的密封方式。试验表明:较之幕墙板片之间的双面粘接,采用三面粘接十分不利,各项力学指标均显著下降,严重降低其密封性及防水功能,应当避免采用三面粘合的密封技术。At present,the curtain wall structure has been widely used,but the plate in the case of temperature fluctuations and structural deformation,may appear displacement,resulting in different stress states of joints.Therefore,in order to ensure the firmness of the joints,a sealing method which can resist displacement and maintain good adhesion must be choose.The results shows that compared with the double-sided bonding between the screen wall plates,the application of three-sided bonding is very unfavorable,and the mechanical indexes are significantly reduced,which seriously reduces its sealing and waterproof function,thus the application of three-sided bonding sealing technology should be avoided.
