Walls with joint structure, joint construction method, and one-component room temperature moisture-curable sealant composition

摘要

PROBLEM TO BE SOLVED: To provide a wall having a joint part structure, a construction method for the joint part and one solution ordinary temperature wet hardening type sealing material composition, which has low modification ratio in modulus even after exposure to heat, can maintain flexibility, is constructed with sealing material having low reduction in extension upon destruction even under immersed state in water and after exposure to heat, and can reduce accidents such as water leak.SOLUTION: A wall having a joint part structure for a structural object comprises a first adherend 10, a second adherend 12 arranged at an adjacent position to the first adherend 10 with an interposed gap, and one solution ordinary temperature wet hardening type sealing material 20 which fills the gap and has a low modification ratio in modulus.SELECTED DRAWING: Figure 1
