ここで図1では、改修用支持架台1の周辺部において既設防水層4が不連続になっている。これは改修用支持架台1の張出部1cを下地5の上に直接接地させるため、その周辺の既設防水層4および断熱材6を一部撤去したためである。本改修構造においては既設支持部材3を撤去する必要はなく、既設支持部材3に改修用支持架台1を覆い被せて下地5に接地し固定する作業ができるスペースが確保できるだけ撤去すればよいので、廃材が多く出る心配がない。また図1では既設防水層4の下に断熱材6が設けられた構造であるが、例えば既設防水層4である防水シート4aが直接下地5の上に設けられた構造である場合には、既設防水層4を撤去せずとも改修用支持架台1は下地5の上に安定的に設置固定することが可能であり、本発明の改修防水構造において既設防水層4の一部撤去は必ずしも必要ではない。図1のように改修用支持架台1の周辺の既設防水層4および断熱材6を一部撤去した場合には、改修用支持架台1を設置した周辺の空間に断熱材8などを充填することで結露を防ぐことができる。 Here, in FIG. 1, the existing waterproof layer 4 is discontinuous in the peripheral portion of the repair support frame 1. This is because the existing waterproof layer 4 and the heat insulating material 6 around the overhanging portion 1c of the repair support stand 1 are partially removed in order to directly ground the overhanging portion 1c on the base 5. In this repair structure, it is not necessary to remove the existing support member 3, and the existing support member 3 may be removed as much as possible to cover the repair support frame 1 and to secure a space for grounding and fixing to the base 5. There is no need to worry about a lot of waste material. Further, in FIG. 1, the structure is such that the heat insulating material 6 is provided under the existing waterproof layer 4, but for example, in the case where the waterproof sheet 4a which is the existing waterproof layer 4 is provided directly on the base 5. The repair support stand 1 can be stably installed and fixed on the base 5 without removing the existing waterproof layer 4, and it is not always necessary to partially remove the existing waterproof layer 4 in the repair waterproof structure of the present invention. is not. When the existing waterproof layer 4 and the heat insulating material 6 around the repair support frame 1 are partially removed as shown in FIG. 1, the space around the repair support frame 1 is filled with the heat insulating material 8 or the like.

既設防水層4と新設防水層2との間には絶縁層7が敷設されることが好ましい。絶縁層7としては絶縁シートや無機質板などを用いることができる。また防水シート2aと側板1a−2とを水密状態に接合するため、改修用支持架台1は少なくともその表面が防水シート2aと密着性のよいものからなることが好ましい。例えば、防水シート2aがポリ塩化ビニル系樹脂製のものであれば、改修用支持架台1の表面はポリ塩化ビニル系樹脂で覆われていることが好ましい。
なお、新設防水シート2aと改修用支持架台1の接合端縁部等にはシーラー等による端末処理を施しても良い。
It is preferable that the insulating layer 7 is laid between the existing waterproof layer 4 and the new waterproof layer 2. As the insulating layer 7, an insulating sheet, an inorganic plate, or the like can be used. Further, since the waterproof sheet 2a and the side plates 1a-2 are joined in a watertight state, it is preferable that at least the surface of the repair support pedestal 1 has good adhesion to the waterproof sheet 2a. For example, if the waterproof sheet 2a is made of a polyvinyl chloride resin, it is preferable that the surface of the repair support frame 1 is covered with the polyvinyl chloride resin.
The joint end edge of the new waterproof sheet 2a and the repair support frame 1 may be terminally treated with a sealer or the like.
