LAMINATED JOINT MATERIAL, SLIT STRUCTURE, AND CONSTRUCTION METHOD OF SLIT
PROBLEM TO BE SOLVED: To provide a joint material that readily resumes to an original state, even when deformed temporarily by external pressure.SOLUTION: A laminated joint material for solving the problem is installed in a slit formed between a concrete structure and another concrete structure, and is a laminated body comprising a first layer, a second layer, and a third layer of different materials. The first layer is made of a material with fire-resisting performance higher than the second layer. The second layer is made of a material with elasticity higher than the first layer. The third layer is laminated on the first layer that is laminated with the second layer, on a surface other than a surface opposite the second layer, and is made of a material having tensile strength higher than the first layer and restitutive force higher than the first layer for resuming to an original flat state from a distorted state caused by pressure, after the pressure has been removed.SELECTED DRAWING: Figure 2
【課題】 外部からの圧力により一時的に形状が変形しても、元の状態に容易に復元可能な目地材を提供する。【解決手段】 コンクリート構造体と他のコンクリート構造体と間に設けられるスリット内に、設置される積層目地材は、材質が異なる第１層と第２層と第３層を含んで構成される積層体であり、前記第１層は、前記第２層に比して高い耐火性能を備えた材料からなり、前記第２層は、前記第１層に比して高い弾性を備えた材料からなり、前記第３層は、前記第２層と積層された該第１層のうち、該第２層と対抗する面とは異なる面に積層され、該第１層に比して引っ張り強度が強く、かつ加圧されて歪んだ状態から該加圧がなくなって元の平面状態へ戻る復元力が該第１層に比して強い性質を有する材料からなることにより、上記課題の解決を図る。【選択図】図２
