The elongation per unit length of seam crossing resilient glue material 16-1 is far smaller than elastic sealant 9, and its elastic extension is generally not more than 3%, can meet the requirement of flexible joint adhesive strength, just can transmission internal force, there is again certain elasticity, and adapt to necessarily distortion.
And the elastic extension of elastic sealant 9 can reach even 10 times of several times, the larger tensile strength of elongation rate is lower.Do not require that elastic sealant 9 has the effect of transmission power, the effect of application elastic sealant 9 is:
1), can't see in appearance crack; 2), there is waterproof, windbreak function.
Therefore, adopting elastic sealant 9 is double insurances of butt joint processing.
When wider in gap, may in adhesives 16, need to add micro-expanding agent.
And the elastic extension of elastic sealant 9 can reach even 10 times of several times, the larger tensile strength of elongation rate is lower.Do not require that elastic sealant 9 has the effect of transmission power, the effect of application elastic sealant 9 is:
1), can't see in appearance crack;
2), there is waterproof action.
Therefore, adopting elastic sealant 9 is double insurances of butt joint processing.
The assembling body of wall adaptive deformation of flexible joint structure is good, and good endurance when wider in gap, may need to add micro-expanding agent in adhesives 16.
