[0002] In modern buildings, parapets, as an important part of the roof structure, not only play a role in beautifying the appearance, but also bear the important responsibility of waterproofing. However, due to various reasons, leakage problems often occur at the root of the parapet, posing a serious threat to the safety and service life of the building. Therefore, it is particularly important to research and develop an effective waterproof structure for the root of the parapet of the building roof.
[0003] When the parapet base waterproof structure is used, the following defects still exist: the waterproof membrane is exposed to the outside and is prone to aging and softening due to long-term exposure to the sun, thus affecting the waterproof effect; the waterproof membrane is prone to hollowing when laid to the inner corner of the parapet base, thus affecting the uniform coverage of the membrane; the waterproof membrane on the parapet is prone to curling for a long time, thereby allowing water to penetrate from the gaps and cause roof leakage.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Reference Figure 1-Figure 4 The utility model provides an embodiment: a waterproof structure for the parapet wall root of a building roof, comprising a parapet wall 1, a concrete line 2 is fixedly connected to the parapet wall 1, a water outlet 3 is arranged on the parapet wall 1, a filter screen 4 is fixedly connected to the water outlet 3, an arc angle 5 is arranged on the parapet wall 1, a roof 12 is fixedly connected to the parapet wall 1, a first layer 6 is arranged on the parapet wall 1, a second layer 7 is arranged on the first layer 6, a steel mesh 8 is arranged on the second layer 7, a protective layer 9 is arranged on the steel mesh 8, a pressing plate 10 is arranged on the steel mesh 8, and a rivet 11 is arranged on the pressing plate 10. When constructing the waterproof structure for the parapet wall root of the building roof, the water outlet 3 is used to ensure that rainwater can be discharged quickly and effectively when it accumulates, and the leakage problem of the roof 12 and the root of the parapet wall 1 caused by excessive water accumulation is prevented. The waterproof performance of the building is improved by multi-layered waterproof materials, thereby enhancing the durability of the building structure. The arc angle 5 is arranged at the base layer, which effectively avoids the problem of bubbling or hollowing of the waterproof layer, and ensures the firm bonding between the waterproof layer and the base layer.
[0023] A third layer 13 is provided on the roof 12, a fourth layer 14 is provided on the third layer 13, a fifth layer 15 is provided on the fourth layer 14, a steel mesh 17 is provided on the fifth layer 15, a protective layer 2 16 is provided inside the steel mesh 17, a separation seam 20 is provided on the steel mesh 17, a sealing paste 18 is provided on the separation seam 20, a sixth layer 19 is provided on the sealing paste 18, the first layer 6 is made of polymer modified asphalt waterproof coating, the second layer 7 is made of self-adhesive polymer modified asphalt waterproof membrane, the third layer 13 is made of non-curing rubber asphalt waterproof coating, the fourth layer 14 is made of elastomeric polymer modified asphalt waterproof membrane, the fifth layer 15 is made of B parapet 1 flame retardant extruded polystyrene board, and the sixth layer 19 is made of S BS self-adhesive waterproof membrane, rivet 11 is arranged at the upper end of the second layer 7, concrete line 2 is arranged at the upper end of rivet 11, sealing paste 18 is arranged in the partition joint 20, and the sixth layer 19 is arranged above the sealing paste 18. When constructing the waterproof structure of the parapet root of the building roof, the filter screen 4 on the downspout 3 effectively intercepts the garbage in the rainwater to prevent the blockage of the drainage pipe. The setting of the pressure plate 10 and the wire mesh 8 and the fixation by rivet 11 enhances the sealing of the structure, and further prevents rainwater from penetrating into the structure from the upper end of the second layer 7. The protective layer 9 applied on the outside of the wire mesh 8 and the setting of the concrete line 2 not only enhance the anti-aging performance of the structure, but also improve the water-retaining capacity of the building.
[0024] Working principle: before the roof 12 and the parapet 1 are poured with reinforced concrete, the downspout 3 should be pre-buried and fixed on the parapet 1, and the bottom of the downspout 3 should be placed according to the thickness of the waterproof layer made on the subsequent roof 12, so that after the construction of the waterproof layer and the protective layer is completed, the bottom of the downspout 3 and the surface layer of the steel mesh 17 are balanced, so that rainwater can be discharged outward in time when it rains to prevent excessive water accumulation from causing leakage of the roof 12 and leakage at the root of the parapet 1, and a filter 4 is provided on the downspout 3 to block garbage in the rainwater when draining outward to prevent garbage from clogging the queue pipe, thereby affecting the overall drainage effect. Before waterproofing, the surface of the roof 12 and the parapet 1 should be cleaned and preliminarily leveled, and then the parapet 1 and the roof should be leveled. A fifth layer 15 is made at the inner corner where the roof 12 intersects to prevent hollowing of the inner corner when the subsequent fourth layer 14 is laid and turned up, so that the bonding between the waterproof membrane and the base layer is not strong, resulting in bubbling or hollowing of the waterproof layer, which makes it easy for water to penetrate into the structure and affect the service life of the structure. After the base layer is processed, the third layer 13 and the first layer 6 are evenly applied on the roof 12 and the parapet 1. The material of the first layer 6 is polymer modified asphalt waterproof coating, which has excellent bonding performance and anti-seepage performance. The material of the third layer 13 is non-curing rubber asphalt waterproof coating, which has excellent waterproof performance. Then, the fourth layer 14 is first laid on the third layer 13. The material of the fourth layer 14 is elastomer polymer modified asphalt waterproof membrane, which has excellent waterproof performance , and when paving, it should be turned up on the parapet 1 and paved with a thickness greater than or equal to 300mm to prevent water from leaking from the junction of the parapet 1 and the roof 12 during subsequent precipitation, and then the second layer 7 is laid on the parapet 1. The material of the second layer 7 is a self-adhesive polymer modified asphalt waterproof membrane, which has excellent waterproof performance and is convenient to construct. Then the fifth layer 15 is laid on the fourth layer 14. The material of the fifth layer 15 is B parapet 1 grade flame retardant extruded polystyrene board. The fifth layer 15 can not only play a role in heat preservation, but also provide certain waterproof protection. Then, the second protective layer 16 is poured on the fifth layer 15. When pouring the second protective layer 16, a steel mesh 17 should be placed inside to prevent the surface of the subsequent second protective layer 16 from cracking. While water seeps downward, It is also easy to damage the waterproof layer. After the second protective layer 16 is poured, a separation joint 20 should be set on the second protective layer 16 to prevent the subsequent cracking of the second protective layer 16 due to thermal expansion and contraction, and the separation joint 20 is filled with a sealing paste 18, and a sixth layer 19 is laid on the sealing paste 18. The material of the sixth layer 19 is SBS self-adhesive waterproof membrane to prevent water seepage into the interior due to the setting of the separation joint 20. A steel mesh 8 is provided on the outer side of the second layer 7, and a pressing plate 10 is provided on the upper end of the second layer 7 to press the steel mesh 8 and the upper end of the second layer 7, and then fixed by a rivet 11 to prevent rainwater from penetrating from the upper end of the second layer 7 into the structure, thereby causing leakage, and then a protective layer 9 is applied on the outer side of the steel mesh 8 to protect the second layer 7.To prevent the second layer 7 from aging due to long-term exposure to the sun, thereby reducing its lifespan, a concrete line 2 is provided above the pressing plate 10, which has a certain water-blocking performance when it rains.
