[0020] like Figure 1 As shown, a parapet waterproof structure of a preferred embodiment of the utility model comprises: a wall 1, a beam 2, a Z-shaped flashing board 3, a roof panel 4, a first waterproof layer 5, a polyester cloth 6, a second waterproof layer 7 and a third waterproof layer 8; for the convenience of description, refer to Figure 1 , now define the length direction of the beam 2 as the first direction X, and the width direction of the beam 2 as the second direction Y, wherein the wall 1 is arranged vertically; the beam 2 extends along the first direction X and is arranged in contact with the first side wall 11 of the wall 1, and the first side wall 11 of the wall 1 is perpendicular to the first direction X, and the roof panel 4 is arranged on the beam 2. In order to avoid leakage at the joint between the roof panel 4 and the first side wall 11, one end of the roof panel 4 close to the wall extends upward to fit the first side wall 11, and extends back to the first direction X and is inserted into the wall 1; one end of the Z-shaped flashing plate fits the roof panel 4 and is inserted into the wall 1, and the lower end surface of the other end is in contact with the upper end surface of the roof panel 4, and one end of the Z-shaped flashing plate 3 is inserted into the wall 1, and the lower end surface of the other end is in contact with the upper end surface of the roof panel 4. After that, a multi-layer waterproof layer needs to be provided. Specifically, refer to Figure 1 A first waterproof layer 5, a polyester cloth 6, a second waterproof layer 7 and a third waterproof layer 8 are sequentially stacked on the upper end surface of the roof panel 4 and the first side wall 11, wherein the first waterproof layer 5 covers the Z-shaped flashing board 3, thereby realizing the laying of multiple layers of waterproof lines.

[0021] Specifically, the wall 1 is cast with concrete. In order to facilitate the positioning of the Z-shaped flashing plate 3 during installation, refer to Figure 1A mounting groove 12 is provided on the first side wall 11 of the wall 1 along the second direction Y, and the second direction Y is perpendicular to the first direction X. One end of the roof panel 4 and the Z-shaped flashing plate 3 are both clamped in the mounting groove 12, so that the Z-shaped flashing plate 3 and the roof panel 4 can be quickly positioned during installation. Specifically, in order to ensure that the Z-shaped flashing plate 3 has a certain anti-leakage effect after installation, the depth of the mounting groove 12 is greater than or equal to 30 mm, which can be adjusted according to actual waterproofing requirements. The Z-shaped flashing plate 3 is made of metal material, generally stainless steel or aluminum alloy, and has a good anti-corrosion effect. Furthermore, in order to reduce the size of the Z-shaped flashing plate 3, refer to Figure 1 The length of one end of the Z-shaped flashing plate 3 facing the beam 2 and extending along the first direction X is less than the length of the roof panel 4. When the beam 2 is arranged, in order to ensure the structural strength of the beam 2 and further reduce the weight of the beam 2, in this embodiment, the beam 2 is made of I-beam.

[0022] Furthermore, in this embodiment, the first waterproof layer 5, the polyester cloth 6, the second waterproof layer 7 and the third waterproof layer 8 are kept flush with the two ends of the wall 1, so as to completely cover the joint between the roof panel 4 and the first side wall 11, ensuring that each waterproof layer has a good anti-leakage effect. In this embodiment, the first waterproof layer 5 and the second waterproof layer 7 use base coatings, which can improve the adhesion of the upper attachments. The third waterproof layer 8 uses a surface coating, which is mainly in contact with external moisture and has the characteristics of aging resistance, pollution resistance, good mildew resistance, moisture resistance, etc. The thickness of each waterproof layer is between 1mm-5mm. A polyester cloth 6 is provided between the first waterproof layer 5 and the second waterproof layer 7, so that the water vapor formed by the temperature change of the waterproof layer can be discharged in time, thereby improving the service life of the waterproof layer. In addition, the strength and tensile crack resistance of the overall waterproof layer can be strengthened, and the overall waterproof structure is more stable and reliable. Furthermore, in order to improve the structural strength of the roof panel 4, the roof panel 4 is made of stainless steel or aluminum alloy.

[0023] The construction process of the utility model is as follows: the wall 1 is poured and the installation groove 12 is reserved, the roof panel 4 is laid after the crossbeam 2 is installed, one end of the Z-shaped flashing plate 3 is inserted into the installation groove 12, and the lower end surface of the other end is arranged in contact with the roof panel 4, and then the first waterproof layer 5 is coated on the first side wall 11 and the roof panel 4, so that the first waterproof layer 5 completely covers the Z-shaped flashing plate 3, and then the polyester cloth 6 is laid on the first waterproof layer 5, and the polyester cloth 6 completely covers the first waterproof layer 5, and then the second waterproof layer 7 and the third waterproof layer 8 are coated on the polyester cloth 6 in sequence. The overall structure is simple, the construction is convenient, and the durability is good.

[0024] In summary, the embodiment of the utility model provides a waterproof structure of a parapet, wherein one end of the roof panel 4 close to the wall 1 extends upward to fit the first side wall 11, and extends in the opposite direction to the first direction X to be inserted into the wall 1, one end of the Z-shaped flashing plate 3 fits the roof panel 4 and is inserted into the wall 1, and the lower end surface of the other end fits with the upper end surface of the roof panel 4, and the first waterproof layer 5, polyester cloth 6, second waterproof layer 7 and third waterproof layer 8 are stacked in sequence on the upper end surface of the roof panel 4 and the first side wall 11, and the first waterproof layer 5 covers the Z-shaped flashing plate 3 to prevent rainwater from leaking from the joint between the beam 2 and the first side wall 11, and at the same time, multiple waterproof layers are provided to form multiple waterproof lines to ensure the normal use of the building and improve the service life, with a simple structure, convenient construction and good durability.
