[0002] After the construction of the building roof structure layer is completed, it is necessary to lay the roof waterproof layer, among which the waterproofing at the root of the roof parapet is a weak link; when laying the roof waterproof layer, the roof waterproof layer should be turned up to the parapet facade by no less than 250 mm. In order to protect this part of the waterproofing and avoid water accumulation at the root of the parapet, an arc-shaped flashing protective layer is formed at the root of the parapet. This part of the turned-up protective layer adopts fine stone concrete to prevent the damage and aging of the root of the roof parapet and leakage; the existing flashing protective layer structure is constructed by manual labor. First, the root of the parapet is cast into a small slope concrete layer shape with fine stone concrete, and then the arc surface is formed by manual labor. When the flashing protective layer is applied at the root of the inner corner of the 90-degree corner of the roof parapet, the corner wall hinders the use of manual tools, resulting in a longer application time for the flashing protective layer, and the arc surface forming effect is very poor. The flashing protective layer at the inner corner is prone to form pores and hollowing, which becomes a hidden danger with a high probability of leakage. Summary of the invention
