ROOFTOP WATERPROOF STRUCTURE
To establish both of suppression of construction costs and retention of water proof properties for a long period of time.SOLUTION: A rooftop waterproof structure has waterproof sheets 3, 4 laid on a waterproof substrate 1 to be a construction object, the waterproof sheets fixed on the waterproof substrate 1 in a spot-like manner using many sheet fixtures 6, 8 arranged in a spot-like manner. The rooftop waterproof structure comprises: a first waterproof part provided in an outer peripheral region A of the waterproof substrate 1; and a second waterproof part provided in an inner peripheral region B inside the outer peripheral region A. In the first waterproof part, the sheet fixtures 8 are fixed on the waterproof substrate 1 in a state in which the waterproof sheets 3, 4 are pressed from above by the sheet fixtures 8, and an extension sheet 9 is fixed to peripheral parts of the waterproof sheets 3, 4, which are positioned in the outer periphery of the sheet fixtures 8 in a state in which the sheet fixtures 8 and the peripheral parts are covered from above. In the second waterproof part, the waterproof sheet 4 is laid on the top side of the sheet fixtures 6 and fixed on the sheet fixtures 6 in a state in which the sheet fixtures 6 are fixed on the waterproof substrate 1.SELECTED DRAWING: Figure 1
【課題】施工コストの抑制と長期に亘る防水性の保持との両立。【解決手段】施工対象となる防水下地１に敷設された防水シート３，４が、点状に配置された多数のシート固定具６，８によって防水下地１に点状に固定された屋上防水構造。防水下地１における外周領域Ａに設けられた第一防水部と、外周領域Ａよりも内側の内周領域Ｂに設けられた第二防水部と、が備えられている。第一防水部においては、シート固定具８によって防水シート３，４を上側から押さえつけた状態でシート固定具８が防水下地１に固定され、かつ、シート固定具８と防水シート３，４のうちのシート固定具８の外周に位置する周囲部分とを上側から覆う状態で、増貼り用シート９が周囲部分に固定されている。第二防水部においては、シート固定具６が防水下地１に固定された状態で防水シート４がシート固定具６の上側に敷設されてシート固定具６に固定されている。【選択図】図１
