[China Glass Net] When designing the rubber joint, we must first consider the width and depth of the rubber joint. The depth of the rubber joint should be between (6-12) mm. The too deep glue joint is not conducive to the deep curing of the sealant. It is too shallow. The seam sealing performance is not good, the width must be greater than or equal to the depth, not less than the depth, and the width to depth ratio is generally between 1:1 and 2:1. The following factors should be considered when designing the width: (1) the area of ​​the curtain wall unit; (2) the thermal expansion and contraction coefficient of the material; and (3) the local temperature difference. From this, the displacement of the glue joint which may change due to the temperature change is calculated, and the large value of the possible displacement must be within the displacement capacity of the sealant. The factors to be considered when designing the rubber joint are: convenient construction, good ventilation after sizing, which is beneficial to the curing of the sealant. After the glue is applied, the sealant will not be displaced before it is cured, and will not be buried in the ground or immersed in water. Wait a minute. The structural rubber joints must also consider the factors such as the weight of the curtain wall and the wind pressure, and calculate the long-term load and short-term load that the structural rubber joints are subjected to. According to the mandatory industry standard JCJ102-96 "Technical Specifications for Glass Curtain Wall Engineering" promulgated by the Ministry of Construction, the long-term load does not exceed 0.007N/mm2, and the short-term large load does not exceed 0.14 N/mm2.
