Description

Technical Field

[0001] This application relates to the technical field of roof waterproofing, and particularly to a waterproof structure for roof deformation joints. Background Art

[0002] During the use of a building, it is affected by various natural factors such as temperature, humidity, and foundation settlement, which causes additional stress and deformation inside the structure. Therefore, during the construction process, deformation gaps are reserved between its walls to provide a certain deformation space for the building. Since the gap part is exposed to water for a long time, rainwater leakage is very likely to occur. The existing waterproof structure for roof deformation joints can refer to a method for waterproofing roof deformation joints with the publication number CN110512806A. During the construction process, before bonding the PVC waterproof coiled material to the concrete edge of the deformation joint, an epoxy mortar is first coated on the concrete edge. Since the epoxy mortar is made by mixing epoxy resin and mortar, the mortar has strong adhesion to the concrete, and the epoxy resin has strong adhesion to the PVC waterproof coiled material. Therefore, an adhesive such as epoxy mortar is made by mixing materials with strong adhesion to both, so that the PVC waterproof coiled material can be firmly adhered to the concrete. However, in the existing technology, water accumulation is likely to occur near the deformation gap. If there is too much water accumulation, it will cause the water to penetrate into the deformation gap.

[0003] Therefore, how to reduce the water accumulation phenomenon in the deformation gap has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0012] In a possible implementation manner, it further includes: a top surface protection layer; the top surface protection layer covers the first thermal insulation layer, the waterproof layer and the expansion joint device on the two concrete panels.

[0013] In a possible implementation manner, the expansion joint device includes two bases, a central cover plate and a spring sliding rod assembly; the two bases are symmetrically arranged on the two waterproof platforms respectively; the central cover plate is embedded on the two bases, and the spring sliding rod assembly penetrates through the central cover plate.

[0020] Advantages of the present application

[0021] The waterproof platform is closely combined with the concrete panel, thus forming an effective waterproof barrier. The waterproof platform is higher than the horizontal plane where the concrete panel is located, avoiding rainwater from penetrating into the expansion joint gap from the edge of the concrete panel or accumulating water near the expansion joint gap. At the same time, the waterproof platform provides a stable support surface for the expansion joint device.

[0022] By providing a slope-finding layer, a gentle slope is formed between the waterproof platform and the concrete panel, so as to ensure that rainwater can flow to both sides along the gentle slope, avoiding the accumulation of rainwater near the expansion joint gap and thus preventing rainwater from penetrating into the expansion joint gap, reducing the leakage risk caused by water accumulation.

In some instances, methods, means, elements, and circuits well-known to those skilled in the art are not described in detail to highlight the gist of the present application.

[0033] The present application provides a waterproof structure for a roof deformation joint, as Figures 1 to 3 shown, including: two concrete panels 100, a deformation joint device 200, an isolation layer, a drainage device 300, and a water drainage device 400; a deformation gap 160 is provided between the two concrete panels 100, and waterproof platforms 110 are provided on one side of each of the two concrete panels 100 facing the deformation gap 160; the deformation joint device 200 is arranged on the top surfaces of the two waterproof platforms 110, and one side of the deformation joint device 200 extends into the deformation gap 160 and is applicable to cover the deformation gap 160; leveling layers 120 are arranged between the two waterproof platforms 110 and the top surfaces of the two concrete panels 100 and are applicable to form a gentle slope between the waterproof platforms 110 and the concrete panels 100; the isolation layer covers the top surfaces of the leveling layers 120 and the waterproof platforms 110; the drainage device 300 is arranged in the deformation gap 160 and is applicable to drain the water flowing into the deformation gap 160; the water drainage device 400 is arranged on the bottom surfaces of the two waterproof platforms 110, and the water receiving side of the water drainage device 400 faces the deformation gap 160.

[0034] It should be noted here that a deformation gap 160 is provided between the two concrete panels 100, and the deformation gap 160 is applicable to provide a certain deformation space for the building. The waterproof platforms 110 and the concrete panels 100 are integrally formed, ensuring the tight combination of the waterproof platforms 110 and the concrete panels 100, thereby forming an effective waterproof barrier. The waterproof platforms 110 are higher than the horizontal plane where the concrete panels 100 are located, avoiding rainwater from penetrating into the deformation gap 160 from the edges of the concrete panels 100 or water accumulation near the deformation gap 160. At the same time, the waterproof platforms 110 provide a stable support surface for the deformation joint device 200. The deformation joint device 200 is fixedly installed on the top surfaces of the two waterproof platforms 110. By providing the deformation joint device 200, the stress concentration phenomenon caused by structural deformation when the two concrete panels 100 undergo relative displacement under the action of factors such as temperature, humidity, and load can be avoided, ensuring that the concrete panels 100 and the internal structure are not damaged. Through the design of extending into the deformation gap 160, the deformation joint device 200 can effectively cover the gap and prevent water penetration.

[0035] The slope layer 120 is laid on the top surface of the concrete panel 100 and is fixedly connected to the side of the waterproof platform 110 away from the deformation gap 160. By setting the slope layer 120, a gentle slope is formed between the waterproof platform 110 and the concrete panel 100, so that rainwater can flow to both sides along the gentle slope, avoiding rainwater from gathering near the deformation gap 160 and causing rainwater to penetrate into the deformation gap 160, thereby reducing the risk of leakage caused by water accumulation. The isolation layer is suitable for preventing rainwater from penetrating into the deformation gap 160. The drainage device 300 is fixedly installed on both sides of the deformation gap 160 and fixedly connected to the waterproof platform 110 at both ends. The drainage device 300 drains the water flowing into the deformation gap 160, avoiding the leakage caused by water accumulation in the deformation gap 160. The drainage device 400 is fixedly arranged at the bottom of the two waterproof platforms 110. The drainage device 400 is suitable for collecting and discharging the water flowing into the deformation gap 160. Among them, the slope layer 120 is composed of foam concrete.

[0036] Further, such as Figure 1 , Figure 2 As shown, a first slope angle α is provided between the slope surface of the slope layer 120 and the horizontal plane where the concrete panel 100 is located. The slope layer 120 provides a basic drainage slope for the overall structure. Through its preset first slope angle α, the slope layer 120 can effectively guide rainwater near the deformation gap 160 to flow to both sides along the gentle slope, thereby avoiding water accumulation near the deformation gap 160, which may cause rainwater to penetrate into the deformation gap 160.

[0037] Preferably, the value range of the first slope-finding angle α is: 30°<α<45°. Preferably, the value of the first slope-finding angle α is: 30°.

[0038] In one possible implementation, Figure 1 , Figure 2As shown in the figure, the isolation layer includes a waterproof layer 130 and a first insulation layer 140. The waterproof layer 130 covers the top surfaces of the slope-forming layer 120 and the waterproof platform 110, thereby forming a continuous waterproof barrier. The waterproof layer 130 closely adheres to the top surfaces of the slope-forming layer 120 and the waterproof platform 110. The waterproof layer 130 is suitable for preventing rainwater from penetrating through the slope-forming layer 120 or the waterproof platform 110 into the deformation gap 160. By setting the waterproof layer 130, it can effectively prevent the slope-forming layer 120 and the waterproof platform 110 below the waterproof layer 130 from being eroded by rainwater, and extend the service life of the overall structure. The deformation joint device 200 contacts and connects with the waterproof layer 130 on the top surfaces of the two waterproof platforms 110. The first insulation layer 140 covers the waterproof layer 130, and the first insulation layer 140 closely adheres to the waterproof layer 130. By setting the first insulation layer 140, the structural deformation or cracks of the waterproof layer 130 caused by temperature difference are avoided, the risk of rainwater leakage is reduced, and the waterproof effect of the waterproof layer 130 is enhanced. At the same time, the waterproof layer 130 provides a dry and leak-free environment for the first insulation layer 140, ensuring that the first insulation layer 140 can fully play its insulation role.

[0039] Preferably, the first insulation layer 140 is made of a polystyrene foam plastic board, and the thickness of the first insulation layer 140 is: 100 mm. The waterproof layer 130 is made of a self-adhesive polymer modified asphalt waterproofing membrane, a double-sided self-adhesive polymer modified asphalt waterproofing membrane, and a non-curing rubber asphalt waterproof coating. The thickness of the self-adhesive polymer modified asphalt waterproofing membrane is 3 mm, the thickness of the double-sided self-adhesive polymer modified asphalt waterproofing membrane is 1.5 mm, and the thickness of the non-curing rubber asphalt waterproof coating is 2 mm.

[0040] Furthermore, the first insulation layer 140 and the waterproof layer 130 are connected by a laying method, and the waterproof layer 130 covers the slope-forming layer 120 by a self-adhesive paving method.

[0041] In a possible implementation manner, as Figure 1 、 Figure 2 shown, it also includes a top surface protection layer 150. The top surface protection layer 150 covers the first insulation layer 140 of the two concrete panels 100, the waterproof layer 130 of the two waterproof platforms 110, and the deformation joint device 200. The top surface protection layer 150 is suitable for protecting the internal structure from the influence of the external environment. The slope-forming layer 120, the waterproof layer 130, the first insulation layer 140, and the top surface protection layer 150 are arranged in sequence from bottom to top. This layered design enables each layer to work together, ensuring the stability and durability of the overall structure.

[0042] Further, the top surface protective layer 150 is provided with a second slope angle, where the second slope angle refers to the ratio between the height of the inclination of the top surface protective layer 150 and the horizontal plane where the first insulation layer 140 is located. By setting the second slope angle, the second slope angle of the top surface protective layer 150 can further ensure that rainwater can drain smoothly during the process of flowing through the roof, reducing the possibility of water accumulation. The design of the second slope angle of the top surface protective layer 150 can also be coordinated with the overall style of the building, thereby enhancing the aesthetics of the building.

[0043] Preferably, the ratio between the height of the inclination of the top surface protective layer 150 and the horizontal plane where the first insulation layer 140 is located is 1:12.

[0044] Further, the top surface protective layer 150 is made of fine aggregate concrete, and the value of the thickness of the top surface protective layer 150 is: 50 mm.

[0045] In a possible implementation manner, as Figures 1 to 3 shown, the expansion joint device 200 includes two bases 210, a center cover plate 220, and more than two spring slider assemblies 230. The two bases 210 are respectively symmetrically arranged on the two waterproof platforms 110. The center cover plate 220 is embedded on the two bases 210. The spring slider assemblies 230 are arranged through the center cover plate 220, and more than two slider assemblies are arranged along the longitudinal direction of the center cover plate 220.

[0046] It should be noted here that the two bases 210 are respectively placed on the waterproof layer 130 on the top surfaces of the two waterproof platforms 110. The first expansion bolt 260 passes through the base 210, the waterproof layer 130, and the waterproof platform 110 in sequence, so as to fixedly install the base 210 on the waterproof layer 130 on the top surface of the waterproof platform 110. The base 210 serves as the basic support of the expansion joint device 200, bears the weight and deformation force from the upper structure, and transfers them to the waterproof platform 110. The center cover plate 220 is embedded on the two bases 210 and covers the deformation gap 160. The spring slider assemblies 230 are suitable for connecting the center cover plate 220 with the two bases 210, ensuring the stability of the overall structure of the expansion joint device 200. More than two spring slider assemblies 230 arranged along the longitudinal direction of the center cover plate 220 can more effectively disperse the deformation force generated by the building structure, avoiding damage to a single spring slider assembly 230 due to excessive pressure, and ensuring the safety of the overall building structure.

[0047] Preferably, the distance between more than two spring slider assemblies 230 is equal, and the distance between every two adjacent spring slider assemblies 230 is 500 mm.

[0048] Further, as Figure 3As shown, the spring slide bar assembly 230 includes a spring 232, a slide bar 231, a fastening bolt 233 and a fastening nut 234. On the opposite sides of the two bases 210, there are slide grooves 211 which extend along the body length direction of the base 210. The two ends of the slide bar 231 are slidably arranged in the slide grooves 211, and the body length direction of the slide bar 231 forms a 45° angle with the body length direction of the slide groove 211. The spring 232 is fixedly connected to the slide bar 231 and the body length direction of the spring 232 is perpendicular to the body length direction of the slide bar 231. The spring 232 is adapted to convert the externally applied deformation force into the elastic potential energy inside the spring 232. When the spring 232 deforms, a reaction force will be generated, and the reaction force cancels out the deformation force, avoiding the deformation force directly acting on the building structure. The fastening bolt 233 sequentially passes through the center cover plate 220, the slide bar 231 and the spring 232 and then is connected to the fastening nut 234. When the expansion joint device 200 is subjected to a deformation force, the expansion joint device 200 converts the deformation force into the sliding movement force of the slide bar 231. The center cover plate 220 displaces as the slide bar 231 slides in the slide grooves of the two bases 210, thereby absorbing and alleviating the deformation force, thus avoiding damage to the overall building structure and ensuring the integrity and safety of the building structure.

[0049] Preferably, the slide bar 231 is a stainless steel slide bar of model M6 in the prior art.

[0050] In a possible implementation manner, as Figure 3 shown, a seal 240 is embedded at the gap between the center cover plate 220 and the two bases 210. The seal 240 is located on both sides of the center cover plate 220 and is in close contact with the center cover plate 220 and the base 210 respectively. Among them, the seal 240 is made of an elastic material. By providing the seal 240, a tight sealing barrier is formed between the center cover plate 220 and the two bases 210, ensuring that the expansion joint device 200 can still maintain the sealing effect of the overall structure during deformation, avoiding rainwater from penetrating into the expansion joint 160 through the gap between the center cover plate 220 and the base 210, and ensuring the waterproof performance of the expansion joint device 200.

[0051] Preferably, the seal 240 is a foam plastic rod.

[0052] In a possible implementation manner, as Figure 1 、 Figure 2As shown, the drainage device 300 includes a waterstop 310 and a waterproof belt 320 ; the waterstop 310 and the waterproof belt 320 are both tubular structures with a U-shaped cross-section, and the opening sides of the waterproof belt 320 and the waterstop 310 are both facing the deformation joint device 200 . It should be noted here that the two ends of the waterstop 310 are respectively fixed between the base 210 and the waterproof layer 130 on the top surface of the waterproof platform 110, and the waterstop 310 is located inside the deformation gap 160. If a small amount of water leaks into the deformation gap 160, the waterstop 310 is suitable for preventing the water in the deformation gap 160 from penetrating into the interior of the building. The waterproof belt 320 is located on the side away from the opening of the waterstop 310. The waterproof belt 320 and the waterstop 310 form a double waterproof protection, which further enhances the waterproof performance of the deformation gap 160. A first preset distance is set between the waterproof belt 320 and the waterstop 310. By setting the first preset distance, the waterstop 310 and the waterproof belt 320 can have a certain degree of freedom when they are subjected to deformation force, thereby avoiding damage caused by mutual squeezing or stretching.

[0053] In one possible implementation, Figure 2 As shown, the drainage device 400 has a cross-sectional structure and the opening of the drainage device 400 faces the deformation joint device 200. A drainage vertical pipe 440 is provided at the bottom of the drainage device 400, and the drainage vertical pipe 440 is connected to the drainage device 400.

[0054] It should be noted here that the drainage device 400 is installed at the bottom of the two waterproof platforms 110 through the pressure strip 410, the first pad 420 and the second pad 430, and the bottom of one of the waterproof platforms 110 is provided with a pressure strip 410 and a first pad 420, one end of the pressure strip 410 is tightly fitted with the bottom of the waterproof platform 110, the first pad 420 is tightly fitted with the pressure strip 410 and is located on the side away from the waterproof platform 110, and the other end of the pressure strip 410 is set at a second preset distance from the waterproof platform 110, and the second bolt assembly passes through the first pad 420, the pressure strip 410, the drainage device 400 and the bottom of the waterproof platform 110 in sequence. One end of the drainage device 400 is clamped in the second preset distance formed between the pressure strip 410 and the bottom of the waterproof platform 110, the second pad 430 is tightly fitted with the other end of the drainage device 400 and is located on the side away from the bottom of the waterproof platform 110, and the second bolt assembly is sequentially arranged through the second pad 430, the drainage device 400 and the bottom of another waterproof platform 110, so that the drainage device 400 is fixedly installed to the bottom of the two waterproof platforms 110, and the drainage device 400 with a "J" structure can form a certain water seal effect, thereby preventing external water from flowing back through the drainage device 400 into the deformation gap 160. The drainage vertical pipe 440 is arranged at the bottom of the drainage device 400 and is connected to the drainage device 400, and the drainage device 400 guides the water flow to the drainage vertical pipe 440 to discharge the water in the drainage device 400.

[0055] Further, the drainage device 400 is a drainage ditch made of aluminum alloy material, and the slope of the drainage device 400 relative to the plane where the bottom of the waterproof platform 110 is located is 1%.

[0056] In a possible implementation manner, a fireproof belt 340 is further included; the fireproof belt 340 is arranged in the deformation gap 160 and located between the drainage device 300 and the drainage device 400. It should be noted here that the main structure of the fireproof belt 340 is a tubular structure with a U-shaped cross-section and the opening side faces the drainage device 400. The two sides of the fireproof belt 340 are respectively fixedly arranged on the inner side walls of the deformation gap 160 and are in close contact with the inner side walls of the deformation gap 160. The fireproof belt 340 is suitable for blocking the spread of fire and high-temperature smoke, and buying time for fire fighting and rescue. The design of the U-shaped tubular structure helps the fireproof belt 340 to better fit closely with the inner side walls of the deformation gap 160, so that the fireproof belt 340 can effectively prevent the spread of fire, high-temperature smoke or external fire sources through the deformation gap 160, and improve the overall fireproof performance of the building. The opening side of the fireproof belt 340 faces the drainage device 400, and this design is conducive to guiding the accumulated water in the deformation gap 160 to flow towards the drainage device 400, and avoiding the erosion effect of the accumulated water on the fireproof belt 340 and the building structure. Preferably, the fireproof belt 340 is made of aluminum silicate refractory fiber and metal thin plate.

[0057] In a possible implementation manner, a second thermal insulation layer 330 is arranged in the deformation gap 160, and the second thermal insulation layer 330 is located between the drainage device 300 and the fireproof belt 340. It should be noted here that filling the second thermal insulation layer 330 at the deformation gap 160 can reduce the thermal stress caused by temperature difference, thereby protecting the building structure from the influence of temperature change and humidity erosion, reducing the risk of damage to the building structure, and enhancing the durability of the overall structure. Preferably, the second thermal insulation layer 330 is made of polystyrene foam plastic board.
