Description

Technical Field

[0001] This invention relates to the technical field of waterproof membrane laying, and in particular to a roof structure for laying thermoplastic polyolefin waterproof membrane and its laying method. Background Technology

[0002] In the field of building roofing engineering, waterproofing performance is one of the core indicators for measuring the quality of roof structure. At present, roof waterproofing construction generally adopts the method of laying waterproof membranes. Common types of membranes include modified bitumen waterproof membranes and synthetic polymer waterproof membranes. However, waterproof membranes made of a single material often cannot simultaneously achieve weather resistance, mechanical strength and ease of construction in practical applications.

[0003] For example, while modified bitumen roofing membranes are easy to apply with self-adhesive materials, they have poor aging resistance and puncture resistance. Polymer roofing membranes, although having excellent weather resistance, usually require adhesives for application, which is complex and carries the risk of peeling. In addition, roof structures are prone to stress caused by cracking of the base layer or temperature changes during long-term use, leading to bulging, cracking, or detachment of the overlapping edges of the roofing membrane, which in turn can cause leakage hazards.

[0004] To improve the performance limitations of single-layer waterproof membranes, multi-layer composite waterproof membranes have been gradually promoted and applied in recent years. However, multi-layer composite structures have also brought new construction challenges: due to the increased overall thickness and rigidity of the membrane, higher requirements have been placed on the unwinding resistance, clamping force, and surface condition of the substrate during the unwinding and laying process.

[0005] The existing device works as follows: first, the waterproof membrane is pulled out from the rolled raw material roll. During the unloading process, in order to ensure that the membrane has a certain tension, a certain resistance is applied to the contact between the membrane and the roof and the unloading time, so that the waterproof membrane is in a taut state. This can effectively prevent the laid waterproof membrane from having hollow spots and wrinkles. However, when the waterproof membrane is laid thickly, the suspended part of the waterproof membrane exerts a greater tensile force on the laid waterproof membrane due to its thickness. The resistance to applying tension to the waterproof membrane needs to be increased accordingly. The membrane in contact with the roof is prone to misalignment and movement under the resistance, and the membrane will shift accordingly.

[0006] Therefore, a roof structure for laying thermoplastic polyolefin waterproof membrane and its laying method are proposed to solve the above problems. Summary of the Invention

[0007] To address the aforementioned problems, this invention provides a roof structure for laying thermoplastic polyolefin waterproof membrane and a method for laying the same.

The side of the breathable dust collection box away from the cover box is designed to be breathable, and one end of the breathable dust collection box can be opened. It also includes a dust extraction and transfer component, which is installed at one end of the cover box. The air extraction end of the dust extraction and transfer component passes through the cover box and provides suction to the dust extraction box. The other end of the dust extraction and transfer component is connected to the ventilated dust storage box. The dust extraction and transfer component draws the impurities from the lower side into the dust extraction box and then sends them into the ventilated dust storage box. The cover box is located on the side of the pressure roller near the roll clamping assembly, and a roof grinding and cleaning wheel that can be powered to rotate is installed at the lower end of the cover box near the pressure roller.

[0015] Optionally, a vertical plate is vertically installed at one end of the telescopic pressing plate near the axis of the conveyor belt. The telescopic pressing plate can be elastically extended, and multiple telescopic pressing plates are evenly distributed on the surface of the conveyor belt. During the movement of the conveyor belt, the number of telescopic pressing plates located on the lower side of the conveyor belt is at least two. The bottom surface of the suspension support is equipped with a flat push plate, which is set horizontally and located on the inner ring side of the conveyor belt.

[0018] Optionally, a damping plate is provided on the upper side of the upper support wheel, and a pressure elastic telescopic rod is fixed on the upper surface of the damping plate. The upper end of the pressure elastic telescopic rod is connected to one side of the lower frame.

[0019] In summary, the present invention includes at least one of the following beneficial technical effects: This invention relates to a waterproof membrane composed of a thermoplastic polyolefin surface layer, a reinforcing layer, and a self-adhesive bitumen underlayer. This composite material achieves complementary advantages of different material properties. The thermoplastic polyolefin surface layer provides the membrane with excellent weather resistance, chemical corrosion resistance, and reflective heat insulation. The reinforcing layer enhances the overall mechanical strength, tear resistance, and dimensional stability of the membrane. The self-adhesive bitumen underlayer ensures a strong bond between the membrane and the leveling layer, facilitating easy construction and achieving high bonding strength. The protective surface layer protects the waterproof membrane from direct ultraviolet radiation and mechanical damage, further extending the service life of the roof structure.

[0020] This invention applies pressure to the roofing membrane by using a roll membrane anti-lateral displacement component. When the roll membrane encounters resistance, the pressure applied by the roll membrane anti-lateral displacement component prevents the rolled membrane from moving due to the increased resistance caused by the increase in thickness. At the same time, it ensures that the roll membrane has sufficient tension, effectively preventing wrinkles and air bubbles in the roll membrane.

[0021] In this invention, the telescopic pressing plate, vertical plate, and conveyor belt work together. After the telescopic pressing plate rotates to the underside of the conveyor belt, it applies pressure to the upper surface of the roll material through compression. At the same time, the conveyor belt drives the connected telescopic pressing plate to match the speed of the telescopic drive frame and the released roll material, ensuring that there is no relative displacement between the telescopic pressing plate and the laid roll material during contact. At the same time, at least two telescopic pressing plates are in contact with the roll material, ensuring that there is no gap in the pressing of the roll material by the telescopic pressing plate during the rotation of the conveyor belt.

[0022] This invention utilizes a combination of a breathable dust collection box, a dust extraction box, a transfer plate, and transfer slots. The air pump's suction end provides airflow to the dust extraction box through the corresponding transfer slots and suction connecting pipe, drawing dust from the bottom of the dust extraction box into the corresponding transfer slots. The breathable baffle plate blocks impurities within the transfer slots. As the transfer plate rotates, the transfer slot containing impurities rotates until it connects with the air pump's exhaust end. The airflow from the air pump then blows the impurities from the transfer slots into the breathable dust collection box through the exhaust connecting pipe, completing the collection. This allows the transfer slots to continuously store and transfer impurities as the transfer plate rotates.

[0023] This invention utilizes a grinding and cleaning wheel. As the cover box moves along with the telescopic drive frame, the grinding and cleaning wheel first contacts and rotates to grind the roof surface that the roof roll has not yet touched, smoothing out uneven areas. At the same time, the grinding and cleaning wheel can block larger particles of impurities that cannot be adsorbed inside the cover box, preventing larger impurities from remaining on the roof surface and causing bumps and hollows when the laid roof roll covers the surface of the impurities.

[0026] The following is in conjunction with the appendix Figures 1-10 The present invention will be described in further detail below.

[0027] like Figure 1 As shown, this embodiment of the invention discloses a roof structure for laying thermoplastic polyolefin waterproof membrane, including a roof structure layer 11, and further comprising: Leveling layer 12 is provided on roof structural layer 11; Waterproof membrane layer 13 is provided on leveling layer 12. Waterproof membrane layer 13 is a laminated composite material, including thermoplastic polyolefin top layer 131, reinforcing layer 132 and asphalt self-adhesive bottom layer 133. The reinforcing layer 132 is one of polyester base, glass fiber mesh or polypropylene fiber cloth, and the asphalt self-adhesive base layer 133 is one of modified asphalt, rubber asphalt or polymer asphalt self-adhesive layer. The protective surface layer 14 is applied on the waterproof membrane layer 13.

[0028] like Figure 2 As shown in the figure, this invention also discloses a method for laying thermoplastic polyolefin waterproof membrane in a roof structure, comprising the following steps: S1. Lay a leveling layer 12 on the roof structure layer 11, and after it has cured, treat the surface to form a roughened bonding interface. S2. Move the waterproof membrane layer 13 along the laying path using the laying device to bond the asphalt self-adhesive bottom layer 133 to the surface of the leveling layer 12, and compact and vent air. S3. During the laying of the roll material, the waterproof roll layer 13 is simultaneously subjected to continuous hot air welding, and after melting, it is pressed together to form an integrated waterproof layer. S4. At the edge of the roof, the edge of the waterproof membrane layer 3 is mechanically pressed and locked by pre-embedded anchoring components; like Figures 3-4 As shown, the laying device in step S2 includes: It includes a telescopic drive frame 1, a roll clamping assembly 2, a roll resistance limiting wheel set 3, a roll anti-lateral displacement assembly 4, and a debris handling and storage assembly 5.

[0029] The telescopic drive frame 1 includes an upper frame 1.1 and a lower frame 1.2. A telescopic drive component 1.3 is provided between the upper frame 1.1 and the lower frame 1.2. The telescopic drive component 1.3 can drive the lower frame 1.2 to move relative to the upper frame 1.1. The upper frame 1.1 is equipped with a moving wheel 1.4 that can contact the ground and move, and the moving wheel 1.4 drives the overall movement of the equipment.

[0030] The telescopic drive component 1.3 can be a hydraulic telescopic rod, which drives the upper frame 1.1 and the lower frame 1.2 by extending and retracting the telescopic rod.

[0031] When the moving wheel 1.4 on the upper frame 1.1 touches the ground, the extension and retraction of the telescopic rod will drive the lower frame 1.2 to move; When the lower frame 1.2 touches the ground, the extension and retraction of the telescopic rod will cause the upper frame 1.1 to move.

[0032] In addition, a handrail 1.5 is installed on the upper frame 1.1 to facilitate the user's movement.

[0033] The roll clamping assembly 2 is installed on one side of the lower frame 1.2, and the roll resistance limiting wheel group 3 is installed on the movable side of the lower frame 1.2. The roll resistance limiting wheel group 3 limits the movement trajectory of the roll and applies resistance to the movement of the roll.

[0034] The roll resistance limiting wheel group 3 is located between the roll clamping assembly 2 and the roll anti-lateral displacement assembly 4. The roll anti-lateral displacement assembly 4 is installed on one side of the lower frame 1.2. The roll anti-lateral displacement assembly 4 can adapt to the moving speed of the telescopic drive frame 1 and follow the movement to apply pressure to the laid roll.

[0035] In this embodiment, with the combined use of the roll resistance limiting wheel set 3 and the roll anti-lateral displacement component 4, the roll can be subjected to sufficient tensile force, keeping the roll taut during installation.

[0036] The debris handling and storage assembly 5 is capable of evacuating air. The air evacuation port of the debris handling and storage assembly 5 faces downward. The debris handling and storage assembly 5 is installed on one side of the lower frame 1.2 and is located below the roll material resistance limiting wheel assembly 3.

[0037] like Figures 3-6 As shown, in this embodiment, the roll clamping assembly 2 includes two telescopic clamping discs 21. The two clamping discs 21 are coaxially arranged, and the ends of the two clamping discs 21 that are far apart from each other are connected to the movable side of the lower frame 1.2. When the two clamping discs 21 rotate relative to the telescopic drive frame 1, the length of the telescopic part of the clamping disc 21 is adjusted by the tightness of the bolts.

[0038] In use, depending on the length of the roll, first loosen the bolts of the clamping disc 21 so that the roll is located between the two clamping discs 21. After tightening the two bolts, fix the length of the extended clamping disc 21 and fix the roll wheel between the two clamping discs 21. When the roll is pulled out from the roll wheel, it drives the two clamping discs 21 to rotate.

[0039] The roll resistance limiting wheel assembly 3 includes an upper support wheel 31 and a lower pressure wheel 32.

[0040] The upper support wheel 31 is connected to one side of the lower frame 1.2 at both ends, and the upper support wheel 31 can rotate relative to the lower frame 1.2. The lower pressure wheel 32 is connected to the lower frame 1.2 at both ends, and the lower pressure wheel 32 can rotate relative to the lower frame 1.2.

[0041] In use, the pulled-out roll passes through the upper support roller 31, then through the lower pressure roller 32 near the side of the debris handling and storage component 5, and then passes through the lower pressure roller 32 and under the roll anti-lateral displacement component 4.

[0042] A damping plate 33 is provided on the upper side of the upper support wheel 31. A pressure elastic telescopic rod 34 is fixed on the upper surface of the damping plate 33. The upper end of the pressure elastic telescopic rod 34 is connected to one side of the lower frame 1.2.

[0043] During use, the roll material passes between the damping plate 33 and the upper support wheel 31. The elastic pressure of the pressure elastic telescopic rod 34 pushes the damping plate 33 to apply pressure to the roll material, thus resisting the movement of the roll material.

[0044] like Figures 7-8 As shown, in this embodiment, the roll material anti-lateral displacement assembly 4 includes a suspension support 41, a transmission wheel set 42, a transmission rope 43, and a telescopic pressing plate 44.

[0045] The suspension support 41 is installed on one side of the lower frame 1.2. There are two transmission wheel sets 42, which are rotatably connected to the lower end of the suspension support 41. The transmission wheel sets 42 rotate relative to the suspension support 41. There are two conveyor belts 43. The two transmission wheel sets 42 are respectively engaged with one end of the inner side of the two conveyor belts 43. The two transmission wheel sets 42 drive the two conveyor belts 43 to rotate as they rotate. There are multiple telescopic pressing plates 44. One telescopic end of the telescopic pressing plate 44 is fixed to the two conveyor belts 43.

[0046] In use, the telescopic drive frame 1 moves downward through the suspension support 41, controlling the height of the transmission wheel set 42 and the conveyor belt 43. As the transmission wheel set 42 drives the conveyor belt 43 to rotate, the telescopic pressing plate 44 rotates along with the conveyor belt 43. The speed at which the conveyor belt 43 drives the telescopic pressing plate 44 to move is matched with the moving speed of the telescopic drive frame 1. The telescopic pressing plate 44 does not move relative to the rolled material it is in contact with. When the telescopic pressing plate 44 rotates to the lower side of the conveyor belt 43, the elasticity of the telescopic pressing plate 44 applies pressure to the rolled material on the lower side, pressing the rolled material laid on the roof tightly against the roof. This effectively prevents the rolled material from shifting relative to the roof under the resistance on the upper side, allowing the suspended rolled material to withstand greater tensile resistance and ensuring that the rolled material of sufficient thickness is taut and laid.

[0047] A vertical plate 45 is vertically installed at one end of the telescopic pressing plate 44 near the axis of the conveyor belt 43. The telescopic pressing plate 44 can be elastically extended. Multiple telescopic pressing plates 44 are evenly distributed on the surface of the conveyor belt 43. When the conveyor belt 43 moves, the number of telescopic pressing plates 44 located on the lower side of the conveyor belt 43 is at least two.

[0048] The equidistant telescopic pressing plates 44 can apply pressure evenly to the roll material. At the same time, the design of at least two plates located under the conveyor belt 43 ensures that sufficient pressure can be applied to the roll material. Furthermore, as the conveyor belt 43 rotates, not all telescopic pressing plates 44 will be detached from the roll material, thus maintaining stable pressure on the roll material.

[0049] A flat push plate 46 is installed on the bottom surface of the suspension support 41. The bottom surface of the flat push plate 46 is horizontally set and is located on the inner ring side of the conveyor belt 43. When the telescopic pressing plate 44 moves to the lower side of the conveyor belt 43 along with the conveyor belt 43, the bottom surface of the flat push plate 46 contacts the vertical plate 45. The telescopic pressing plate 44 connected to the vertical plate 45 that contacts the flat push plate 46 is in a vertical state.

[0050] The telescopic pressing plate 44 moves to the lower side of the conveyor belt 43 and the vertical plate 45 connected to the flat push plate 46 comes into contact with the flat push plate 46. The flat push plate 46 and the vertical plate 45 are in a parallel state, which interlocks and drives the telescopic pressing plate 44 to be perpendicular to the flat push plate 46, so that the telescopic pressing plate 44 does not deflect when it comes into contact with the roll material, and steadily applies pressure to the roll material.

[0051] like Figures 9-10 As shown, in this embodiment, the debris handling and storage component 5 includes a cover box 51, a dust extraction box 52, a breathable dust storage box 53, and a dust extraction and transfer component 54.

[0052] The two ends of the cover box 51 are fixed to one side of the lower frame 1.2. The cover box 51 is located under the upper support wheel 31. The dust collection box 52 is located inside the cover box 51. The lower ends of both the dust collection box 52 and the cover box 51 are open. The cover box 51 is located on the side of the lower pressure wheel 32 near the roll clamping assembly 2. The lower end of the cover box 51 near the lower pressure wheel 32 is equipped with a roof grinding and cleaning wheel 55 that can be powered to rotate.

[0053] During use, when the telescopic drive frame 1 controls the pressure roller 32 and the telescopic pressing plate 44 to contact the upper surface of the roll material, the roof grinding and cleaning wheel 55 contacts the roof. When the telescopic drive frame 1 drives the cover box 51 to move above the roof, the lower side of the roof grinding and cleaning wheel 55 rotates relative to the roof in the opposite direction of the movement direction to clean the impurities attached to the roof surface and grind the protruding parts of the roof, blocking the impurities inside the cover box 51 and preventing the impurities from moving between the laid roll material and the roof.

[0054] The ventilated dust collection box 53 is installed on the outside of the cover box 51. The side of the ventilated dust collection box 53 away from the cover box 51 is ventilated. One end of the ventilated dust collection box 53 can be opened, and the airflow blown into the ventilated dust collection box 53 can be discharged, blocking impurities inside the ventilated dust collection box 53. After the ventilated dust collection box 53 is opened, the impurities accumulated inside can be taken out.

[0055] The dust extraction and transfer assembly 54 is installed at one end of the cover box 51. The suction end of the dust extraction and transfer assembly 54 passes through the cover box 51 and provides suction force to the dust extraction box 52. The other end of the dust extraction and transfer assembly 54 is connected to the ventilated dust collection box 53. The dust extraction and transfer assembly 54 draws the impurities from the lower side into the dust extraction box 52 and then sends them into the ventilated dust collection box 53.

[0056] The dust extraction and transfer assembly 54 includes a closed disc cover 541, an air extraction connecting pipe 542, an exhaust connecting pipe 543, a transfer disc 545, and an air pump 547.

[0057] The closed disc cover 541 is installed outside the cover box 51. The two ends of the exhaust connecting pipe 542 pass through the closed disc cover 541 and the outer side of the cover box 51, respectively. The exhaust connecting pipe 542 is located inside the cover box 51 and is fixed to the dust collection box 52. The two ends of the exhaust connecting pipe 543 pass through the breathable dust collection box 53 and the outer side of the cover box 51, respectively.

[0058] The transfer disk 545 is rotatably inserted into the closed disc cover 541. The transfer disk 545 rotates relative to the closed disc cover 541. The end face of the transfer disk 545 has multiple transfer slots 546. A breathable blocking disk 544 is inserted into the inner side of each transfer slot 546. The suction pipe 542 and the exhaust pipe 543 are respectively connected to the adjacent transfer slots 546. The breathable blocking disk 544 allows airflow to pass through while blocking impurities in the transfer slots 546.

[0059] Both the suction end and the exhaust end of the air pump 547 penetrate the outer side of the enclosed disc cover 541. Both the suction end and the exhaust end of the air pump 547 are equipped with pressure valves. The pressure valves ensure that when the transfer slot 546 connected to the suction end and the exhaust end of the air pump 547 cannot flow smoothly, the airflow is connected to the external environment through the pressure valves, preventing the air pump 547 from being damaged. The suction connecting pipe 542 is connected to the suction end of the air pump 547 through the corresponding connected transfer slot 546, and the exhaust connecting pipe 543 is connected to the exhaust end of the air pump 547 through the corresponding connected transfer slot 546.

[0060] Multiple transfer slots 546 are evenly distributed in a circumferential array around the axis of transfer disk 545. Exhaust connecting pipe 543 and suction connecting pipe 542 are evenly distributed in a circumferential array around the axis of transfer disk 545. Suction connecting pipe 542 and exhaust connecting pipe 543 are not connected to the same transfer slot 546 to prevent the outlet and exhaust ends of air pump 547 from being connected to the same transfer slot 546 and thus preventing the transfer of impurities inside.

[0061] During use, the suction end of the air pump 547 provides airflow suction to the dust collection box 52 through the corresponding transfer slot 546 and the suction connecting pipe 542. The airflow carries the impurities on the lower side of the dust collection box 52 into the corresponding transfer slot 546 through the suction connecting pipe 542. The ventilated baffle plate 544 blocks the impurities in the transfer slot 546. Then, as the transfer plate 545 rotates, the transfer slot 546 containing impurities rotates to connect with the exhaust end of the air pump 547. The airflow ejected by the air pump 547 blows the impurities in the transfer slot 546 into the ventilated dust collection box 53 through the exhaust connecting pipe 543 for collection. This allows the transfer slot 546 to continuously store and transfer impurities as it rotates with the transfer plate 545.

[0062] In this embodiment, the lower telescopic part of the telescopic drive frame 1 is equipped with a power box that provides rotational power to the transfer disc 545, the transmission wheel set 42 and the roof grinding and cleaning wheel 55, and the speed of the power box is adjustable so that the telescopic pressing plate 44 is adapted to the moving speed of the telescopic drive frame 1 under the drive of the conveyor belt 43.

[0063] The power box is composed of power transmission components such as motors, gears, and conveyor belts, and is used to transmit rotational power.

[0064] In use, after the thermoplastic polyolefin waterproof membrane is laid on the roof, it is hot-air welded to the roof by a hot air treatment device. The hot air treatment device follows behind the membrane anti-lateral displacement component 4. While the membrane anti-lateral displacement component 4 is pressing the membrane, the laid membrane is hot-air welded in time to prevent the membrane from being laid too long and shifting again due to external force. At the same time, the timely heating of the membrane effectively prevents elastic deformation and rebound during pulling.

[0065] In this embodiment, an adhesive application assembly can be installed between the pressure roller 32 and the cover box 51 to apply adhesive to the part of the roof roll that is in contact with the cleaned roof roll, further preventing the roll from moving due to elastic deformation and further increasing the firmness of the bond between the roll and the roof during hot air welding.

[0066] The working principle is as follows: In the non-working state, the telescopic drive frame 1 retracts to drive the roll material anti-lateral displacement component 4 to detach from the ground, which facilitates the transfer of the equipment. In the working state, the roll material clamping component 2 clamps the two ends of the roll material coaxially. The operator first controls the roll material to be laid on the roof from the underside of the roll material anti-lateral displacement component 4. Then, the lower telescopic part of the telescopic drive frame 1 controls the roll material anti-lateral displacement component 4 to contact the laid roll material. As the telescopic drive frame 1 moves as a whole, the roll material is gradually laid on the roof. The roll material anti-lateral displacement component 4 applies pressure to the roll material laid on the roof. The roll material resistance limiting wheel group 3 limits the movement trajectory of the suspended part of the roll material and applies resistance to the roll material, so that the roll material is released in a stable taut state. Meanwhile, as the telescopic drive frame 1 moves the entire equipment, the debris handling and storage component 5 removes and cleans the impurities that are about to be laid, ensuring the cleanliness of the roof surface that the roll material comes into contact with and reducing the probability of the roll material becoming hollow or wrinkled.

[0067] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
