JOINT STRUCTURE, AND MANUFACTURING METHOD OF JOINT STRUCTURE MEMBER

To achieve simple construction, a shortened construction period, improved reliability of a water proof function, and improved design property.SOLUTION: A joint structure comprises: first to fourth members solidified by a hydration reaction; a joint space among the first to fourth members; a first sheet member having a first embedded portion embedded in the first member and a first extension portion extending from the first member to the joint space; a second sheet member having a second embedded portion embedded in the second member and a second extension portion extending from the second member to the joint space; a third sheet member having a third embedded portion embedded in the third member and a third extension portion extending from the third member to the joint space; and a fourth sheet member having a fourth embedded portion embedded in the fourth member and a fourth extension portion extending from the fourth member to the joint space. The first extension portion is in contact with the second extension portion and the third extension portion. The fourth extension portion is in contact with the second extension portion and the third extension portion.SELECTED DRAWING: Figure 1 【課題】施工の簡易化、工期短縮、防水機能の信頼性向上、及び意匠性の向上を図る。【解決手段】水和反応で固結された第１部材、第２部材、第３部材、及び第４部材と、第１部材と第２部材と第３部材と第４部材との間の目地空間と、を備える目地構造であって、第１部材に埋設された第１埋設部と、第１部材から目地空間に延出した第１延出部と、を有する第１シート部材と、第２部材に埋設された第２埋設部と、第２部材から目地空間に延出した第２延出部と、を有する第２シート部材と、第３部材に埋設された第３埋設部と、第３部材から目地空間に延出した第３延出部と、を有する第３シート部材と、第４部材に埋設された第４埋設部と、第４部材から目地空間に延出した第４延出部と、を有する第４シート部材と、を備え、第１延出部が第２延出部と第３延出部とに接触し、第４延出部が第２延出部と第３延出部とに接触している。【選択図】図１
