Description

Technical Field

[0001] This application relates to the field of building construction, and in particular to a waterproof and thermally insulated roof structure. Background Technology

[0002] A roof refers to the surface of a building's roof, and also the area between the ridge and the eaves. Roofs are generally divided into concrete roofs and metal roofs; public buildings with large roof areas typically use metal roofs.

[0003] Currently, a standing seam roof is disclosed, comprising a support layer, an insulation layer, and a waterproof and breathable membrane layer connected sequentially from bottom to top. Multiple purlins are spaced apart on the side of the waterproof and breathable membrane layer away from the support layer, and purlin supports are fixedly connected to the bottom side of each purlin and the support layer. The purlin supports penetrate the insulation layer and the waterproof and breathable membrane layer. Multiple support plates are fixedly installed on the top side of each purlin support, spaced apart along the length of the purlin. A drainage channel is provided between two adjacent support plates on the same purlin. A star-shaped bracket is fixedly installed on the top side of each support plate, and an arc plate is fixedly installed on the top edge of the drainage channel, covering the star-shaped bracket. Wind-resistant clamps are provided on the support plates to clamp the star-shaped bracket and the arc plate, thereby installing the drainage channel between two support plates. During rain, rainwater enters the drainage channel and is then discharged through the channel's guide. Meanwhile, the drainage trough is installed on the plum blossom head by wind-resistant clips, which reduces the possibility of the drainage trough being blown away by the wind, and at the same time facilitates the thermal expansion and contraction of the drainage trough along its length.

[0004] Regarding the aforementioned technologies, the inventors believe that due to damage from sun exposure or construction errors, some rainwater may enter the waterproof and breathable membrane layer from the drainage channel. The waterproof and breathable membrane layer prevents water from entering the insulation layer, thus reducing the likelihood of the insulation layer absorbing water and becoming damaged. However, the insulation layer is relatively soft, and when rainwater falls into the waterproof and breathable membrane layer, it compresses the membrane layer, causing indentations. Subsequently, the accumulated rainwater damages the waterproof and breathable membrane layer, thus affecting the roof's waterproofing performance. Summary of the Invention

[0005] To improve the waterproofing performance of roofs, this application provides a waterproof and thermally insulated roof structure.

[0006] This application provides a waterproof and thermally insulated roof structure, which adopts the following technical solution:

[0007] A waterproof and thermally insulated roof structure includes a support layer, a thermal insulation layer, and a waterproof and breathable membrane layer connected sequentially from bottom to top. Multiple purlins are spaced apart on the side of the waterproof and breathable membrane layer away from the support layer. A water-blocking plate is provided on the side of the waterproof and breathable membrane layer away from the support layer. Purlin supports are fixedly connected to the bottom side of each purlin and the support layer, and the purlin supports penetrate the thermal insulation layer and the waterproof and breathable membrane layer. Multiple pressure plates are provided on the top side of each purlin, and the pressure plates are spaced apart along the length of the purlin. The water-blocking plate is located between the pressure plates and... Between the purlins, the pressure plate is provided with a first bolt, which passes through the pressure plate and the baffle plate. The first bolt thread passes through the purlin. A support plate is fixedly installed on the side of the pressure plate away from the baffle plate. A drainage trough is provided between two adjacent support plates located on the same purlin. A star-shaped head is fixedly installed on the top side of the support plate. An arc plate is fixedly installed on the top edge of the drainage trough. The arc plate covers the star-shaped head. The star-shaped head is provided with a clamping assembly for clamping the star-shaped head and the arc plate.

[0008] By adopting the above technical solution, after rainwater enters the drainage channel, it is guided out through the channel. If the drainage channel is damaged and leaks, the rainwater will fall into the baffle plate. The baffle plate provides a second layer of waterproofing, reducing the possibility of rainwater directly falling into the waterproof and breathable membrane layer, thereby improving the roof's waterproof performance. The baffle plate is located below the drainage channel, reducing the risk of damage from sun exposure. The clamping assembly clamps the curved plate and the star-shaped head, installing the drainage channel between two support plates. When the drainage channel is exposed to sunlight, it can expand and contract along its length, reducing the risk of damage from sun exposure. The thermal insulation layer improves the roof's thermal insulation performance.

[0009] Optionally, the support layer includes multiple horizontal and vertical beams connected in a crisscross pattern. The support layer also includes multiple first placement plates, which are fixedly installed on the top side of the longitudinal beams. The first placement plates are arranged sequentially along the length of the longitudinal beams, and the purlins pass through the first placement plates and are connected to the longitudinal beams.

[0010] By adopting the above technical solution, the horizontal and vertical beams provide support, thereby reducing the likelihood of roof collapse. Simultaneously, the first placement plate covers the gap formed by the horizontal and vertical beams, facilitating the installation of the insulation layer onto the support layer.

[0011] Optionally, side plates are fixedly installed on both sides of the first placement plate, and the two side plates are inclined away from each other. A second placement plate is fixedly installed between the sides of two adjacent side plates away from the first placement plate. The first placement plate and the side plates are provided with multiple ventilation holes, which are evenly distributed on the first placement plate and the side plates. A vapor barrier layer is fixedly installed on the side of the insulation cotton layer near the support layer. The vapor barrier layer is used to block water vapor and is in contact with the side of the second placement plate away from the support layer.

[0012] By adopting the above technical solution, the vapor barrier prevents moisture from entering the insulation layer, thereby improving the roof's thermal insulation performance. Simultaneously, the vents allow air to pass through the supporting layer, further enhancing the roof's ventilation performance.

[0013] Optionally, the baffle plate is bent to form multiple water guide channels, and the distance between the two side walls of the water guide channels gradually increases from bottom to top.

[0014] By adopting the above technical solution, rainwater falling into the baffle plate enters the water guide channel for collection, and then the rainwater is discharged through the guide channel, thereby reducing the occurrence of rainwater accumulation on the baffle plate.

[0015] Optionally, the clamping assembly includes a second bolt and two clamping blocks arranged opposite each other. Each of the two clamping blocks has a clamping groove on one side opposite to the other for the spline head to enter. The second bolt is located on the side of the spline head away from the support plate. Each of the two clamping blocks has a through hole for the bolt to pass through.

[0016] By adopting the above technical solution, after the arc plates located on both sides of the support plate cover the plum blossom head, two clamping blocks are placed on both sides of the plum blossom head, allowing the plum blossom head to enter the clamping groove. Then, a second bolt is passed through the through hole and tightened, thereby clamping the arc plates and the plum blossom head together, and the drainage trough is installed between the two support plates. When the drainage trough undergoes thermal expansion and contraction, it can slide on the plum blossom head via the arc plates, facilitating thermal expansion and contraction along its length and reducing the likelihood of damage to the drainage trough after exposure to sunlight.

[0017] Optionally, the bottom of the drainage trough is bent away from the support layer to form multiple telescopic parts, which are spaced apart along the width direction of the drainage trough.

[0018] By adopting the above technical solution, when the roof area is large, the amount of rainwater inside the drainage trough is large after rain, which causes the trough to be subjected to downward pressure from the rainwater. The telescopic part allows the trough to bend downward under the pressure of rainwater, thereby increasing the amount of rainwater that the drainage trough can hold and reducing the occurrence of rainwater overflowing from the drainage trough.

[0019] Optionally, the drainage trough is internally equipped with multiple horizontal bars, which are spaced apart along the length of the drainage trough. Each horizontal bar has a vertical bar at both ends, and the vertical bars are fixedly connected to the ends of the horizontal bars and the inner wall of the drainage trough. A clamping assembly is installed on each horizontal bar. The clamping assembly is used to compress the bottom of the drainage trough.

[0020] By adopting the above technical solution, when the wind speed on the roof is high, the side and bottom walls of the drainage trough will repeatedly bend and recover after being blown by the wind, thus causing the entire roof to vibrate. By reinforcing the side walls of the drainage trough with vertical rods and pressing the bottom of the drainage trough with clamping components, the vibration of the drainage trough can be reduced.

[0021] Optionally, there are multiple clamping components, which are spaced apart along the length of the horizontal bar. Each clamping component includes a first connecting rod, a first sleeve, and a pressure block. One end of the first connecting rod is fixedly connected to the body of the horizontal bar. The first sleeve is threaded onto the first connecting rod. The pressure block is fixedly installed on the end of the first sleeve away from the horizontal bar. The side of the pressure block away from the first sleeve abuts against the inner bottom wall of the drainage trough.

[0022] By adopting the above technical solution, the first sleeve is rotated and moved on the first connecting rod, causing the pressure block to move. When the drainage trough is installed between the two support plates, rotating the first sleeve allows the pressure block to abut against the drainage trough body, thereby reducing the likelihood of the bottom of the drainage trough bending under wind. Simultaneously, the pressure block abuts against part of the bottom of the drainage trough body, facilitating rainwater drainage.

[0023] Optionally, multiple first reinforcing plates are fixedly installed on both outer side walls of the drainage trough. The first reinforcing plates are spaced apart along the length of the drainage trough. A second reinforcing plate is provided between the first reinforcing plates on both sides of the drainage trough. The first reinforcing plates have sliding openings along the height direction for the second reinforcing plates to pass through. A guide rod is fixedly installed between the inner walls of the two ends of the sliding opening. A spring is sleeved on the guide rod. The second reinforcing plate has a guide hole for the guide rod to pass through. The spring abuts against the side of the second reinforcing plate away from the drainage trough. The spring is used to drive the second reinforcing plate to press tightly against the outer bottom wall of the drainage trough.

[0024] By adopting the above technical solution, the first reinforcing plate is used to strengthen the sidewall of the drainage ditch, thereby reducing the occurrence of repeated bending and recovery of the sidewall under wind. When there is a lot of rainwater inside the drainage ditch, the bottom of the drainage ditch bends downward. The second reinforcing plate is pressed tightly against the outer bottom wall of the drainage ditch by a spring, thereby reducing the bending amplitude of the bottom of the drainage ditch and thus reducing the possibility of rainwater damaging the drainage ditch.

[0025] Optionally, a sliding rod is provided between the drainage trough and the baffle plate. Multiple second connecting rods are fixedly installed on the body of the sliding rod. The end of the second connecting rod away from the sliding rod passes through the baffle plate and is fixedly connected to the purlin. A third connecting rod is fixedly installed on the bottom surface of the second reinforcing plate. A second sleeve is threaded onto the third connecting rod. A hook is fixedly installed on the end of the second sleeve away from the second reinforcing plate. The hook hooks the sliding rod.

[0026] By adopting the above technical solution, in the event of damage to the clamping component, the hook tightens the sliding rod, thereby reducing the possibility of the drainage tank being blown away by the wind. Simultaneously, the hook slides on the sliding rod, facilitating the thermal expansion and contraction of the drainage tank along its length.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. After the drainage channel leaks, the rainwater first falls into the baffle plate, which blocks the rainwater and reduces the possibility of rainwater falling directly into the waterproof and breathable membrane layer. At the same time, the baffle plate is located below the drainage channel, so it is not easily damaged by sun exposure, thereby improving the waterproof performance of the roof.

[0029] 2. By pressing the bottom of the drainage trough with the clamping component, the wind resistance of the drainage trough is improved, thereby reducing the vibration of the drainage trough after being blown by the wind. Attached Figure Description

[0044] The following is in conjunction with the appendix Figure 1-13 This application will be described in further detail.

[0045] Example 1.

[0046] This application discloses a waterproof and heat-insulating roof structure.

[0047] Reference Figure 1 , Figure 2 A waterproof and heat-insulating roof structure includes a support layer 4, a vapor barrier layer 1, a heat insulation cotton layer 2, and a waterproof and breathable membrane layer 3 connected sequentially from bottom to top.

[0048] Reference Figure 3 , Figure 4The support layer 4 includes a first placement plate 41, a crossbeam 42, and a longitudinal beam 43. There are multiple crossbeams 42 and longitudinal beams 43, which are connected in an alternating pattern, with the longitudinal beams 43 located on the top side of the crossbeams 42. The first placement plate 41 is parallel to the crossbeams 42, and the first placement plate 41 is spaced apart along the length of the longitudinal beams 43.

[0049] Reference Figure 3 , Figure 4 Side plates 5 are fixedly installed on both sides of the first placement plate 41, and the two side plates 5 are set at an angle away from each other. A second placement plate 6 is fixedly installed between the sides of two adjacent side plates 5 that are away from the first placement plate 41. The insulation cotton layer 2 is placed on the second placement plate 6. Both the first placement plate 41 and the side plates 5 have multiple ventilation holes 7, which are evenly and densely distributed on the first placement plate 41 and the side plates 5.

[0050] Side panel 5 elevates the second placement plate 6 away from the first placement plate 41, creating a space between the insulation layer and the first placement plate 41 for ventilation. Air from inside the building enters the insulation layer 2 through vents 7 and then exits through the waterproof and breathable membrane layer 3, thus improving the roof's breathability. Horizontal beams 42 and longitudinal beams 43 provide support, reducing the likelihood of roof collapse. The vapor barrier 1, made of spun polyethylene and polytetrafluoroethylene, prevents moisture from entering the insulation layer while allowing air to pass through, thus protecting the insulation layer 2.

[0051] Reference Figure 2 , Figure 3 A purlin 8 is provided on the top side of the longitudinal beam 43, and multiple purlin supports 9 are fixedly installed between the purlin 8 and the longitudinal beam 43. The purlin supports 9 are spaced apart along the length of the longitudinal beam 43. The purlin supports 9 penetrate the vapor barrier layer 1, the thermal insulation layer 2, and the waterproof and breathable membrane layer 3.

[0052] Reference Figure 5 The top surface of the waterproof and breathable membrane layer 3 is at a height less than or equal to the top side of the purlin 8.

[0053] Reference Figure 6 , Figure 7 A water baffle 10 is provided on the side of the waterproof and breathable membrane layer 3 away from the insulation cotton layer 2. The water baffle 10 is bent to form multiple water guiding channels 11, and the distance between the two side walls of the water guiding channels 11 gradually increases from bottom to top. The water guiding channels 11 are spaced apart along the length of the longitudinal beam 43.

[0054] Reference Figure 6 , Figure 7Multiple pressure plates 12 are provided on the top side of the purlin 8. The pressure plates 12 are spaced apart along the length of the purlin 8 and abut against the side of the baffle plate 10 away from the purlin 8. A first bolt 13 is provided on the pressure plate 12. The first bolt 13 passes through the pressure plate 12 and the baffle plate 10 and is screwed into the purlin 8. Tightening the first bolt 13 allows the pressure plate 12 to press the baffle plate 10 against the top side of the purlin 8, thereby connecting the baffle plate 10 and the purlin 8.

[0055] After rainwater falls into the baffle plate 10, it is guided out by the drainage channel 11. The baffle plate 10 protects the waterproof and breathable membrane layer 3, thereby reducing the occurrence of rainwater falling into the waterproof and breathable membrane layer 3 and improving the waterproof performance of the roof.

[0056] Reference Figure 7 , Figure 8 The baffle plate 10 has multiple drainage channels 14 on the side away from the purlin 8, and the drainage channels 14 are spaced apart along the length of the purlin 8. A support plate 15 is fixedly installed on the side of the pressure plate 12 away from the purlin 8, and a drainage channel 14 is located between each two adjacent support plates 15 on the same purlin 8. A perforated head 16 is fixedly installed on the top side of the support plate 15, and an arc plate 17 is fixedly installed on the top edge of the drainage channel 14. The arc plate 17 covers the perforated head 16, thus allowing the drainage channel 14 to hang between two support plates 15.

[0057] Reference Figure 8 , Figure 9 The support plate 15 is equipped with a clamping assembly 18, which includes a second bolt 181 and two clamping blocks 182, arranged opposite to each other. Each clamping block 182 has a clamping groove 19 on its opposite side for the sprite head 16 to enter. The second bolt 181 is located on the side of the sprite head 16 away from the support plate 15, and each clamping block 182 has a through hole 20 for the second bolt 181 to pass through. After the arc plates 17 on both sides of the support plate 15 enclose the sprite head 16, the two clamping blocks 182 press against the sprite head 16 and the sliding plate. Then, the second bolt 181 is tightened through the through hole 20, thereby clamping the sprite head 16 and the sliding plate, thus allowing the drainage trough 14 to be installed between the two support plates 15. During thermal expansion and contraction, the drainage trough 14 expands and contracts along its length, reducing the risk of damage after exposure to sunlight.

[0058] The width of the clamping block 182 gradually increases from one side near the purlin 8 to the other, which helps to increase the clamping force of the clamping block 182 on the sprite head 16 and the arc plate 17. Of the two clamping blocks 182, one clamping block 182 is fixedly equipped with a locking block 22, and the other clamping block 182 has a locking groove 23 for the locking block 22 to pass through. The locking block 22 and the locking groove 23 cooperate to facilitate the alignment of the two clamping blocks 182 with each other.

[0059] Reference Figure 8 The bottom of the drainage trough 14 bends away from the supporting layer 4, forming multiple expansion joints 21. These expansion joints 21 are spaced apart along the width of the drainage trough 14. During rain, the roof area is large, and the rainfall is heavy, potentially increasing the amount of rainwater inside the drainage trough 14. The bottom of the drainage trough 14 is compressed downwards by the rainwater, and the expansion joints 21 cause the drainage trough 14 to bend downwards, thereby increasing its capacity and reducing the possibility of rainwater overflowing. Simultaneously, the bending of the drainage trough 14 helps reduce the risk of excessive rainwater damaging it. Roofs are generally constructed with some slope, and the water guide trough 11 and drainage trough 14 are sloped downwards from one end to the other.

[0060] The implementation principle of a waterproof and thermally insulated roof structure according to this application embodiment is as follows: When it rains, rainwater enters the drainage channel 14, which drains the rainwater from the roof. When the drainage channel 14 leaks, the rainwater falls into the baffle plate 10 and is discharged after being collected in the water guide channel 11, thereby reducing the occurrence of rainwater directly falling into the waterproof and breathable membrane layer 3. At the same time, the baffle plate 10 is located below the water guide channel 11, thereby reducing the occurrence of damage to the baffle plate 10 after exposure to sunlight. By reducing the amount of rainwater falling into the waterproof and breathable membrane layer 3, the occurrence of the waterproof and breathable membrane layer 3 sinking and accumulating rainwater under the weight of the rain is reduced, thereby improving the waterproof performance of the roof. At the same time, the thermal insulation performance of the roof is improved by the thermal insulation cotton layer 2.

[0061] Example 2.

[0062] This application discloses a waterproof and heat-insulating roof structure.

[0063] Reference Figure 10 , Figure 11 The difference between the waterproof and thermally insulated roof structure of this application embodiment and Embodiment 1 is that multiple horizontal rods 24 are provided inside the drainage channel 14, and the horizontal rods 24 are spaced apart along the length of the drainage channel 14. The ends of the horizontal rods 24 face the side wall of the drainage channel 14. Vertical rods 25 are provided at both ends of the horizontal rods 24, and the ends of the horizontal rods 24 are fixedly connected to the bodies of the vertical rods 25. The bodies of the vertical rods 25 are also fixedly connected to the inner side wall of the drainage channel 14.

[0064] Wind speeds are generally high on the roof surface and low below the drainage channel 14, creating a negative pressure that pushes the drainage channel 14. Under this negative pressure, the drainage channel 14 continuously bends and deforms before returning to its original shape, causing the entire roof to vibrate. By reinforcing the sidewalls of the drainage channel 14 with vertical rods 25, the occurrence of this bending and deformation under negative pressure is reduced, thus decreasing roof vibration. Reducing roof vibration decreases the likelihood of the clamping assembly 18 detaching from the spline head 16 and causing leakage from the drainage channel 14, thereby improving the roof's waterproofing capability.

[0065] Reference Figure 10 , Figure 11 The horizontal bar 24 is equipped with multiple clamping components 26, which are spaced apart along the length of the horizontal bar 24. Each clamping component 26 includes a first connecting rod 261, a first sleeve 262, and a pressure block 263. One end of the first connecting rod 261 is fixedly connected to the body of the horizontal bar 24, and the first sleeve 262 is threaded onto the first connecting rod 261. The pressure block 263 is fixedly installed at the end of the first sleeve 262 away from the horizontal bar 24. When the drainage trough 14 is installed between the two support plates 15, rotating the first sleeve 262 causes the pressure block 263 to press against the inner bottom wall of the drainage trough 14. The pressure block 263 restricts the upward bending deformation of the inner bottom wall of the drainage trough 14 due to negative pressure, thereby reducing the occurrence of roof vibration caused by repeated bending of the bottom of the drainage trough 14.

[0066] Reference Figure 12 , 13 Multiple first reinforcing plates 27 are fixedly installed on both outer side walls of the drainage trough 14, and the first reinforcing plates 27 are spaced apart along the length of the drainage trough 14. The first reinforcing plates 27 on both sides of the drainage trough 14 correspond one-to-one. The first reinforcing plates 27 are used to reinforce the side walls of the drainage trough 14, thereby reducing the occurrence of the side walls of the drainage trough 14 continuously bending and deforming and then recovering under the push of negative pressure, and thus reducing the occurrence of roof vibration.

[0067] A second reinforcing plate 28 is disposed between the two first reinforcing plates 27. The first reinforcing plates 27 have sliding openings 29 along their height for the second reinforcing plate 28 to pass through. Guide rods 30 are fixedly installed between the inner walls of both ends of the sliding openings 29, and springs 31 are sleeved on the guide rods 30. The second reinforcing plate 28 has guide holes 32 for the guide rods 30 to pass through, and the springs 31 abut against the side of the second reinforcing plate 28 away from the drainage trough 14. The springs 31 are used to drive the second reinforcing plate 28 to press tightly against the outer bottom wall of the drainage trough 14. When rainwater accumulates inside the drainage trough 14, the bottom side of the drainage trough 14 bends downwards. The second reinforcing plate 28 supports the bottom of the drainage trough 14, thereby reducing the possibility of damage due to excessive bending of the drainage trough 14.

[0068] Reference Figure 12 , 13 A sliding rod 33 is provided between the water guide channel 11 and the baffle plate 10. Multiple second connecting rods 34 are fixedly installed on the body of the sliding rod 33. The end of each second connecting rod 34 away from the sliding rod 33 passes through the baffle plate 10 and is fixedly connected to the purlin 8. A third connecting rod 35 is fixedly installed on the bottom surface of the second reinforcing plate 28. A second sleeve 36 is threaded onto the third connecting rod 35. A hook 37 is fixedly installed on the end of the second sleeve 36 away from the second reinforcing plate 28. The hook 37 is used to hook the sliding rod 33.

[0069] Hook 37 hooks onto sliding rod 33. When the drainage tank 14 expands and contracts due to heat, hook 37 slides on sliding rod 33, thus facilitating the expansion and contraction of the drainage tank 14. When the drainage tank 14 is blown open by the wind, hook 37 hooks onto sliding rod 33, thus facilitating the temporary fixation of the drainage tank 14 for maintenance.

[0070] The implementation principle of the waterproof and thermally insulated roof structure in this application embodiment is as follows: the air velocity above the drainage channel 14 is generally greater than the air velocity below the drainage channel 14, thereby subjecting the drainage channel 14 to an upward negative pressure. When the drainage channel 14 is subjected to an upward negative pressure, the pressure block 263 compresses the inner bottom wall of the drainage channel 14, and the first reinforcing plate 27 and the vertical rod 25 reinforce the side wall of the drainage channel 14, thereby reducing the occurrence of repeated bending and recovery of the drainage channel 14 under the influence of negative pressure, and thus reducing the occurrence of roof vibration.

[0071] 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.
