Parapet 2 may be a lining structure secured to structural layer 1. The parapet wall 2 is arranged at the outer edge of the structural layer 1, and the parapet wall 2 is perpendicular to the structural layer 1. The waterproof layer 3 is arranged on one side of the structural layer 1 far away from the indoor space. The waterproof layer 3 is used for waterproofing the structural layer 1, so that the structural layer 1 is not easy to generate water seepage.

The waterproof layer 3 includes a waterproof paint layer 31 and a waterproof roll layer 32. The waterproof paint layer 31 and the waterproof roll layer 32 are sequentially arranged along the direction far away from the structural layer 1. The waterproof coating layer 31 is mainly formed by coating asphalt polyurethane waterproof coating, and has strong toughness, strong adaptability to base layer expansion or cracking and high tensile strength. The waterproof roll layer 32 is mainly formed by laying a self-adhesive waterproof roll. Usually, the waterproofing of the structural layer 1 is mainly performed by the waterproofing roll layer 32, and if the waterproofing roll layer 32 has defects such as being locally punctured in the production process or the construction process, the structural layer 1 can still perform the waterproofing function through the waterproofing coating layer 31, so that the waterproofing effect of the waterproofing layer 3 is more reliable.

And a leveling layer 4 is arranged between the waterproof coating layer 31 and the structural layer 1. The leveling layer 4 is mainly formed by laying fine aggregate concrete. Because the screed 4 still needs to bear load, the compressive strength grade of the screed 4 should be higher, so that the screed 4 can be made of C25 fine-stone concrete. Leveling layer 4 is used for making level to structural layer 1 to make waterproof coating layer 31's construction plane more level and smooth, thereby make waterproof coating layer 31's shaping effect better.

One end of the waterproof layer 3 close to the parapet wall 2 is provided with an extension part 5 fixedly connected with the parapet wall 2. The extension 5 conforms to the structure of the waterproof layer 3. When the waterproof coating layer 31 is used for coating construction, the asphalt polyurethane waterproof coating is extended and coated on the parapet wall 2, then the waterproof roll material layer 32 is used for laying construction, the self-adhesive waterproof roll material is extended, adhered and fixed on the parapet wall 2, and the extension part 5 can be machined and molded. The extension part 5 is used as a waterproof structure at the joint of the parapet wall 2 and the structural layer 1, so that water seepage is not easily generated at the joint of the parapet wall 2 and the structural layer 1.

After the construction of the extension part 5 is completed, the fastener 51 is firstly penetrated through the extension part 5 and is nailed into the groove wall of the open groove 21, and then the coating construction of the filling layer 7 is carried out. The fastening member 51 serves to enhance the coupling effect between the extension portion 5 and the parapet wall 2, thereby making it more difficult for the end of the extension portion 5 to be warped or the like.

And a protective layer 8 is arranged on one side of the waterproof layer 3, which is far away from the structural layer 1. The protective layer 8 is coated with cement mortar. After the waterproof layer 3 is constructed, the protective layer 8 can be coated on the waterproof layer 3. The protective layer 8 serves as a peripheral protective structure of the waterproof layer 3, so that the waterproof layer 3 is not easily damaged and the waterproof effect of the waterproof layer 3 is not deteriorated. When the protective layer 8 is constructed, the protective layer 8 is extended and coated on the parapet wall 2, and the filling layer 7 is embedded and filled in the open slot 21, namely the protective layer 8 and the filling layer 7 are of an integral structure.
