DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] Example: The present invention provides a parapet waterproof structure to prevent cracking, see Figure 1-Figure 5 The invention comprises a parapet 200 disposed on the top of the roof 100, a waterproofing membrane 300 is laid between the parapet 200 and the top of the roof 100, a first waterproof layer 400 is disposed on the outside of the waterproofing membrane 300, a protective layer 500 is disposed on the outside of the first waterproof layer 400, and an anti-cracking net 600 is sandwiched inside the protective layer 500; a positioning groove 210 is disposed on the side of the parapet close to the waterproofing membrane 300, the positioning groove 210 is disposed horizontally, and at least one group is disposed along the vertical direction; a positioning assembly 700 is disposed in the positioning groove 210 for fixing the protective net. The present application can further improve the waterproofing effect of the parapet by disposing the first waterproof layer 400 on the outside of the waterproofing membrane 300. At the same time, by disposing the anti-cracking net 600 in the protective layer 500 and by fastening and fixing the anti-cracking net 600 with the positioning assembly 700, the problem of cracking and delamination of the protective layer 500 can be reduced, thereby improving the overall waterproofing effect of the parapet.

[0027] The lower and upper sidewalls of the positioning groove 210 are each formed with a limit strip 220. The inner wall of the positioning groove 210 is paved with a waterproofing membrane 300. A concrete layer 230 is cast inside the positioning groove 210 and within the waterproofing membrane 300, with the limit strip 220 located inside the concrete layer 230. One end of the positioning assembly 700 is embedded in the concrete layer 230, and the other end is connected to the protective net. This arrangement allows the waterproofing membrane 300 to bypass the positioning groove 210 from the bottom, achieving waterproofing at the positioning groove 210. At the same time, the positioning assembly 700 is located outside the waterproofing membrane 300. While securing the anti-cracking net 600, the positioning assembly 700 does not penetrate the waterproofing membrane 300, thereby preventing it from damaging the waterproofing effect of the waterproofing membrane 300. At the same time, the limiting strip 220 formed on the inner wall of the positioning groove 210 can strengthen and fix the concrete layer 230 poured in the positioning groove 210, so that the concrete layer 230 and the waterproof membrane 300 are kept in close fit. At the same time, a certain pulling force can be provided to the positioning component 700, so that it can further fix the anti-cracking net 600.

[0028] The positioning assembly 700 includes a positioning sleeve 710 and a positioning member 720. A first positioning plate 730 is integrally formed at one end of the positioning sleeve 710, which is provided with a plurality of connecting holes 731. The other end of the positioning sleeve 710 is positioned outside the concrete layer 230. The positioning member 720 includes a connecting rod 721, one end of which is threaded into the positioning sleeve 710 and the other end passes through the anti-crack net 600. A fixing plate is provided, comprising a cross-shaped connecting rod 722 and a fixing ring 723 located outside the connecting rod 722. This arrangement not only strengthens the fixation of the anti-crack net 600 but also further reduces delamination.

[0029] A second waterproof layer 410 is integrally formed within the positioning groove 210 and outside the concrete layer 230. The second waterproof layer 410 is integrally cast with the first waterproof layer 400. A second positioning plate 740 is provided within the second waterproof layer 410 and is threadedly connected to the outside of the positioning sleeve 710. The outer end of the positioning sleeve 710 is located within the first waterproof layer 400. The second positioning plate 740 is used to pull the second waterproof layer 410 together, providing a pulling force between the second waterproof layer 410 and the first waterproof layer 400, thereby improving the tightness between the first waterproof layer 400, the second waterproof layer 410, and the waterproof membrane 300 and reducing delamination between them. Furthermore, the second waterproof layer 410 further waterproofs the positioning groove 210, preventing water from penetrating into the positioning groove 210.

[0030] A top baffle 240 is cast on the top of the parapet 200 , and a side end of the top baffle 240 protrudes from the parapet 200 .

[0031] A waterproof closing 250 is formed on one side of the parapet 200 close to the waterproof membrane 300 and on one end close to the top baffle 240; the upper ends of the waterproof membrane 300, the first waterproof layer 400, the protective layer 500 and the anti-cracking net 600 are all located on the inner side of the waterproof closing 250; a fastening assembly 800 is arranged in the waterproof closing 250.

[0032] Fastening assembly 800 includes a vertically positioned reinforcing rib 810, one end of which is prefabricated within parapet 200 and the other end is located inside waterproofing closure 250. A V-shaped plate 820 is positioned inside waterproofing closure 250, with one side of V-shaped plate 820 abutting the upper end of waterproofing closure 250 and the other side abutting protective layer 500. A fixing layer 830 is also cast within waterproofing closure 250.

[0033] The V-shaped plate 820 includes a horizontally disposed first abutment plate 821 and an obliquely disposed second abutment plate 822. The first abutment plate 821 abuts against the upper side of the waterproof closure 250, while the second abutment plate 822 abuts against the protective layer 500. A plurality of interlocking grooves 823 are spaced apart on the first and second abutment plates 821, 822. The reinforcing ribs 810 pass through the interlocking grooves 823 and are fixedly connected to the fixing layer 830. After the fixing layer 830 is cast, the fixing layer 830 is interlocked and fixed to the reinforcing ribs 810. Simultaneously, the fixing layer 830 passes through the interlocking grooves 823 and is bonded to the protective layer 500. The fixing layer 830 also forms a limiting effect on the V-shaped plate 820, allowing the V-shaped plate 820 to press the upper ends of the waterproof membrane 300, the first waterproof layer 400, the protective layer 500, and the anti-cracking net 600.

[0034] A retaining edge 260 is formed on the upper side of the parapet and outside the waterproof closing 250, and the lower end of the retaining edge 260 abuts the outside of the protective layer 500. The retaining edge 260 can prevent rainwater from entering the waterproof closing 250 along the edge of the parapet and prevent rainwater from penetrating into the parapet from the end.

[0035] More preferably, a first reinforcement cage 900 is formed inside the parapet 200, and a second reinforcement cage 910 is disposed within the roof 100, with the first and second reinforcement cages 900 and 910 connected. Multiple reinforcement bundles 920 are horizontally formed within the first reinforcement cage 900, with the bundles 920 positioned between adjacent positioning slots 210 and spaced apart. The arrangement of the first and second reinforcement cages 900, 910, and the reinforcement bundles 920 further enhances the strength of the parapet and improves its protective effectiveness.

[0036] The present invention provides a crack-resistant parapet waterproof structure. By disposing a first waterproof layer 400 on the outside of a waterproof membrane 300, the waterproofing effect of the parapet can be further improved. Simultaneously, by disposing an anti-crack net 600 within a protective layer 500 and securing the anti-crack net 600 with a positioning assembly 700, the problem of cracking and delamination of the protective layer 500 can be reduced, thereby improving the integrity and waterproofing performance of the parapet. Furthermore, the present invention achieves waterproofing at the positioning groove 210 by allowing the waterproof membrane 300 to bypass the positioning groove 210 from the bottom. Furthermore, the positioning assembly 700 is located on the outside of the waterproof membrane 300. While securing the anti-crack net 600, the positioning assembly 700 does not penetrate the waterproof membrane 300, thereby preventing the waterproofing effect of the waterproof membrane 300 from being compromised. At the same time, the limiting strip 220 formed on the inner wall of the positioning groove 210 can strengthen and fix the concrete layer 230 poured in the positioning groove 210, so that the concrete layer 230 and the waterproof membrane 300 are kept in close fit. At the same time, a certain pulling force can be provided to the positioning component 700, so that it can further fix the anti-cracking net 600.
