Description

Technical Field

[0001] This application relates to the field of building waterproofing, and in particular to a waterproof sealing structure for roofs and walls. Background Technology

[0002] In the construction industry, waterproofing and sealing of roofs and walls has always been a crucial aspect. A good waterproof sealing structure can effectively prevent rainwater penetration, protect the building structure from moisture erosion, and avoid problems such as mold and peeling walls, thereby ensuring the safety and comfort of the building.

[0003] Currently, the industry mainly offers the following solutions for waterproofing the connection between roofs and walls: First, hot-melt application of asphalt-based waterproof membranes, where heating causes the membrane to bond to the substrate; second, multiple coats of polymer cement waterproof coatings to form a continuous waterproof layer; and third, the use of prefabricated metal flashing in conjunction with sealant. However, asphalt membrane application requires open flame work, posing safety hazards, and is prone to dripping in high-temperature environments; waterproof coatings require a high degree of substrate flatness, and their thickness is difficult to control; metal flashings are greatly affected by temperature deformation, and sealant is prone to aging and cracking.

[0004] In response to the aforementioned technologies, the inventor provides a waterproof sealing structure for roofs and walls. Utility Model Content

[0005] To improve the waterproofing effect between the roof and the wall, this application provides a waterproof sealing structure between the roof and the wall.

[0006] The waterproof sealing structure for roofs and walls provided in this application adopts the following technical solution: A waterproof sealing structure for a roof and wall includes a parapet wall, a canopy roof arranged vertically on the parapet wall, and support columns for supporting the canopy roof. The parapet wall is provided with a waterproof membrane extending to the top of the parapet wall. A fixing assembly for fixing the waterproof membrane is provided at the top of the parapet wall. The fixing assembly includes an embedded part installed in the parapet wall, a fixing member for pressing the waterproof membrane against the parapet wall, and a first sealing strip installed in the fixing member and sealingly engaging with the waterproof membrane. A filling layer, which is a polyurethane foam filling material, is provided between the fixing member and the waterproof membrane.

[0007] By adopting the above technical solution, the basic framework of the waterproof and sealing structure is formed by setting up parapet walls, canopy roofs and supporting columns. Waterproof membrane is installed on the parapet walls and extends to the top. The waterproof membrane is fixed with fixing components, which can effectively prevent rainwater penetration. The embedded parts, fixing parts and the first sealing strip in the fixing components can ensure that the waterproof membrane is firmly fixed and well sealed. A polyurethane foam filling layer is set between the fixing parts and the waterproof membrane to fill the gaps and enhance the waterproof effect.

[0008] Optionally, the fixing component includes a fixing seat installed on the parapet wall and cooperating with the embedded part, and a fixing cover plate installed on the side of the fixing seat facing away from the parapet wall. The fixing seat and the fixing cover plate are connected by a locking structure. The locking structure includes a locking groove opened in the fixing seat, an installation groove opened in the fixing cover plate, and a locking component installed in the installation groove and cooperating with the locking groove. The inner side of the fixing cover plate has a second sealing strip that abuts against the fixing seat.

[0009] By adopting the above technical solution, the specific structure of the fastener is disclosed. The fixing cover plate is connected to the fixing seat through the locking structure, making the fastener installation more stable. The locking component cooperates with the locking groove to achieve locking, which facilitates the installation and disassembly of the fixing seat and the fixing cover plate. The second sealing strip abuts against the fixing seat, which enhances the sealing performance of the fastener, reduces the possibility of rainwater penetrating into the interior of the parapet wall, and further improves the waterproof effect of the roof and wall waterproof sealing structure.

[0010] Optionally, the locking assembly includes a locking housing mounted in the mounting slot, a locking member slidably mounted in the locking housing, and a locking spring mounted in the locking housing and driving the locking member to always be driven away from the locking housing. The locking housing has a locking opening, and one end of the locking spring is connected to the locking housing and the other end is connected to the locking member.

[0011] By adopting the above technical solution, the specific structure of the locking assembly is disclosed. Through the cooperation between the locking housing, locking element, and locking spring of the locking assembly, the fixing seat and the fixing cover plate are stably connected. The locking spring drives the locking element away from the locking housing and engages with the locking groove, enhancing the stability of the connection between the fixing seat and the fixing cover plate. This ensures the compression effect on the waterproof membrane and improves the waterproof performance of the waterproof sealing structure. Simultaneously, a second sealing strip is provided on the inner side of the fixing cover plate to further enhance the waterproof sealing effect.

[0012] Optionally, the top surface of the fixed cover plate has a guide slope that is arranged to be inclined downwards away from the fixed cover plate.

[0013] By adopting the above technical solution, the setting of the guide slope on the top surface of the fixed cover plate can guide rainwater to flow away from the fixed cover plate, avoid rainwater accumulation on the fixed cover plate, and further improve the waterproof performance.

[0014] Optionally, the top of the parapet wall is provided with pressing grooves spaced apart along the length of the parapet wall, and a sealing strip is provided in the pressing groove for pressing the waterproof membrane into the pressing groove. The sealing strip is arranged between the waterproof membrane and the fastener. When the sealing strip is arranged in the pressing groove, the top surface of the sealing strip is flush with the top surface of the parapet wall.

[0015] By adopting the above technical solution, the waterproof membrane can be pressed into the pressing groove by setting the pressing groove and the sealing strip, which enhances the adhesion between the waterproof membrane and the parapet wall and improves the waterproof effect. In addition, the sealing strip is arranged between the parapet wall and the fastener and its top surface is flush with the top surface of the parapet wall, making the structure flatter and facilitating the subsequent installation of the fastener. At the same time, it avoids the sealing strip protruding and affecting the stability of the waterproof sealing structure.

[0016] Optionally, the connection between the parapet wall and the canopy roof is an arc transition, and a buffer layer is also provided at the connection between the parapet wall and the canopy roof. The buffer layer includes a waterproof coating, a non-woven fabric layer and a waterproof coating in sequence from the connection away from the parapet wall and the canopy roof.

[0017] By adopting the above technical solution, the parapet wall and the canopy roof are connected by an arc transition, which can reduce rainwater accumulation. The buffer layer is set at the connection between the two and is composed of a waterproof coating, a non-woven fabric layer and a waterproof coating, which can enhance the waterproof performance of the connection. At the same time, the non-woven fabric layer can play a buffering role and reduce the impact of structural deformation and other factors on the waterproof performance.

[0018] Optionally, the top surface of the canopy roof is provided with guide grooves spaced apart along the length of the canopy roof.

[0019] By adopting the above technical solution, a drainage channel is opened on the top surface of the canopy roof, which allows rainwater on the canopy roof to flow along the drainage channel, effectively guiding rainwater discharge, preventing rainwater from accumulating on the canopy roof, enhancing the roof's drainage capacity, and improving the waterproof effect of the waterproof sealing structure between the roof and the wall.

[0020] Optionally, the height of the waterproof membrane shall not be less than 250 mm.

[0021] By adopting the above technical solution and installing waterproof membrane with a height of not less than 250mm, the waterproof performance at the junction of the roof and the wall can be enhanced, effectively preventing rainwater from penetrating into the wall.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. This application constructs a basic framework for a waterproof and sealed structure by setting up a parapet wall, a canopy roof, and supporting columns. A waterproof membrane is installed on the parapet wall and extends to the top. The waterproof membrane is fixed with fixing components, which can effectively prevent rainwater penetration. The embedded parts, fixing parts, and first sealing strip in the fixing components can ensure that the waterproof membrane is firmly fixed and well sealed. A polyurethane foam filling layer is set between the fixing parts and the waterproof membrane to fill the gaps and enhance the waterproof effect. 2. The locking assembly, through the cooperation of its locking housing, locking element, and locking spring, ensures a stable connection between the fixing seat and the fixing cover. The locking spring drives the locking element away from the locking housing and into the locking groove, enhancing the stability of the connection between the fixing seat and the fixing cover. This ensures effective compression of the waterproof membrane and improves the waterproof performance of the waterproof sealing structure. Furthermore, the fixing cover has a second sealing strip on its inner side, further strengthening the waterproof sealing effect. 3. By fixing the arrangement of the top surface of the cover plate and setting the drainage channel on the roof of the canopy, the probability of rainwater accumulation is reduced, thereby improving the waterproof effect.

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses a waterproof sealing structure for roofs and walls. (Refer to...) Figure 1 A waterproof sealing structure for a roof and walls includes a parapet wall 1, a canopy roof 2 perpendicularly arranged on the parapet wall 1, and support columns 3 arranged parallel to the parapet wall 1 for supporting the canopy roof 2. A waterproof membrane 11 is provided on the top surface of the parapet wall 1, with one end extending to the top of the parapet wall 1 and the other end positioned on the top surface of the canopy roof 2. The height of the waterproof membrane 11 is not less than 250 mm. In this embodiment, the height of the waterproof membrane 11 is 250 mm.

[0031] Reference Figure 2 To achieve a sealed fixation of the waterproof membrane 11 on the parapet wall 1, the waterproof membrane 11 is fixed to the parapet wall 1 with screws, and the screw locations are filled with sealant. Simultaneously, a fixing assembly 4 for fixing the waterproof membrane 11 is provided at the top of the parapet wall 1. The fixing assembly 4 includes an embedded part 41 installed at the top of the parapet wall 1, a fixing member 42 for pressing the waterproof membrane 11 against the parapet wall 1, and a first sealing strip 43 installed on the fixing member 42 and sealingly engaging with the waterproof membrane 11. The fixing member 42 includes a fixing seat 421 installed on the parapet wall 1 and engaging with the embedded part 41, and a fixing cover plate 422 installed on the side of the fixing seat 421 facing away from the parapet wall 1. The fixing seat 421 has a U-shaped cross-section with an downward opening, thus pressing the waterproof membrane 11 against the top surface of the parapet wall 1. The embedded part 41 has an external thread structure, and the fixing seat 421 and the embedded part 41 are connected and fixed by a nut, with a washer placed between the nut and the fixing seat 421.

[0032] Reference Figure 2 and Figure 3 The fixing base 421 and the fixing cover plate 422 are connected by a locking structure. The locking structure includes locking grooves 4211 on both sides of the fixing base 421, a mounting groove 4221 on the fixing cover plate 422, and a locking assembly 5 installed in the mounting groove 4221 and cooperating with the locking groove 4211. The locking assembly 5 includes a locking housing 51 installed in the mounting groove 4221, a locking member 52 slidably installed in the locking housing 51, and a locking spring 53 installed in the locking housing 51. The locking housing 51 has a locking opening 511. One end of the locking spring 53 is connected to the inner wall of the locking housing 51, and the other end is connected to the locking member 52, causing the locking member 52 to always tend to disengage from the locking housing 51. To reduce the probability of rainwater seeping into the wall, a second sealing strip 4222 is provided on the inner side of the fixing cover plate 422 to abut against the fixing base 421.

[0033] Reference Figure 2 In order to reduce the probability of rainwater accumulating on the top of the fixed cover plate 422, the top surface of the fixed cover plate 422 has a guide slope 4223 that is arranged to be inclined downward away from the fixed cover plate 422.

[0034] Reference Figure 2 To improve the sealing effect between the fastener 42 and the waterproof membrane 11, a filling layer 12 is provided between the fastener 42 and the waterproof membrane 11. The filling layer 12 is a polyurethane foam filling material. Polyurethane foam is a flexible material with a closed-cell structure. After being compressed by the fastener 42, it will undergo recoverable elastic deformation, which allows it to continuously and tightly fill all the gaps between the fastener 42 and the irregular membrane surface, forming an impeccable seal and effectively reducing the probability of water vapor intruding from all directions.

[0035] Reference Figure 2 To further improve the fit between the waterproof membrane 11 and the parapet wall 1, a pressing groove 13 is provided at intervals along the length of the parapet wall 1 at its top. A sealing strip 131 is provided within the pressing groove 13, and the sealing strip 131 is positioned between the waterproof membrane 11 and the fixing seat 421 of the fixing component 42. The sealing strip 131 helps to press the waterproof membrane 11 tightly within the pressing groove 13, achieving initial fixation of the waterproof membrane 11 on the parapet wall 1, which facilitates subsequent cooperation between the waterproof membrane 11 and the fixing component 4. When the sealing strip 131 is positioned within the pressing groove 13, its top surface is flush with the top surface of the parapet wall 1, reducing the impact of the sealing strip 131 on the stability of the waterproof structure.

[0036] Reference Figure 4 To improve the connection strength between the parapet wall 1 and the canopy roof 2, the connection between the parapet wall 1 and the canopy roof 2 is a rounded transition. In addition, a buffer layer 14 is provided at the connection between the parapet wall 1 and the canopy roof 2. The buffer layer 14 includes a waterproof coating 141, a non-woven fabric layer 142 and a waterproof coating 141 in sequence, which helps to enhance the waterproof performance of the connection. At the same time, the non-woven fabric layer 142 can play a buffering role and reduce the impact of structural deformation and other factors on the waterproof performance.

[0037] Reference Figure 5 In order to guide the discharge of rainwater on the roof 2, the top surface of the roof 2 is provided with guide channels 21 at intervals along the length of the roof 2.

[0038] The implementation principle of a waterproof sealing structure for a roof and wall in this application embodiment is as follows: The basic framework of the waterproof sealing structure is formed by setting up a parapet wall 1, a canopy roof 2, and a support column 3. A waterproof membrane 11 is set on the parapet wall 1 and extends to the top. The waterproof membrane 11 is fixed with the fixing component 4, which can effectively prevent rainwater penetration. The setting of the embedded part 41, the fixing part 42, and the first sealing strip 43 in the fixing component 4 can ensure that the waterproof membrane 11 is firmly fixed and well sealed. A polyurethane foam filling layer 12 is set between the fixing part 42 and the waterproof membrane 11 to fill the gaps and enhance the waterproof effect. Furthermore, the setting of the top surface guide slope 4223 of the fixed cover plate 422 and the guide groove 21 on the canopy roof 2 helps to reduce the probability of rainwater accumulation, further improving the waterproof effect of the roof and wall.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
