Description

Technical Field

[0001] This invention relates to the field of waterproof membrane laying technology, and specifically to a waterproof membrane laying device. Background Technology

[0002] Waterproof membrane is a flexible building material used in building walls, roofs, tunnels, highways, landfills, etc., to resist external rainwater and groundwater seepage. Its main products include asphalt waterproof membrane and polymer waterproof membrane.

[0003] Chinese patent document CN216973982U discloses a waterproof membrane laying and fixing device for waterproof construction in building engineering. The device includes a box, on which the membrane is placed on a support column at the top of the box. The membrane is pulled out and laid on the ground between two rolling tubes. It moves backward so that the rolling roller presses on the membrane. At the same time, several flame-spraying tubes fixed on one side of the box spray flames outward to heat-melt the membrane. The rolling roller rolls on the heat-melted membrane to firmly lay the membrane on the ground.

[0004] However, in the above scheme, the fixed setting of the flame tube for point heating may cause local overheating of the waterproof membrane, resulting in burn-through or uneven melting of the adhesive, which will affect the bonding strength between the membrane and the substrate. Summary of the Invention

[0005] This invention provides a waterproof membrane laying device to solve the problems of local overheating of the membrane leading to burn-through or uneven melting of the adhesive in the prior art.

[0006] In a first aspect, the present invention provides a waterproof membrane laying device, comprising: a trolley, a membrane roller, a pressing assembly, and a heating assembly; the membrane roller is rotatably mounted on the trolley and is used to install waterproof membrane; the pressing assembly includes a mounting frame and a pressing roller, the mounting frame is mounted on the trolley, the pressing roller is rotatably mounted on the mounting frame, the central axis of the pressing roller is parallel to the central axis of the membrane roller, and the pressing roller is used to press the waterproof membrane onto the ground; the heating assembly is disposed on the side of the mounting frame near the membrane roller, the heating assembly includes a flame gun, a moving assembly, and a transmission assembly, the transmission assembly is disposed between the moving assembly and the pressing roller, the flame gun is disposed at the drive end of the moving assembly, and the pressing roller drives the moving assembly through the transmission assembly to drive the flame gun to reciprocate along the axial direction of the pressing roller.

[0007] Beneficial Effects: The waterproof membrane is installed on a roll roller. After the membrane passes over the pressure roller, it is pressed onto the ground substrate. Pulling the trolley causes the friction on the membrane surface to rotate the pressure roller, thus rolling and laying the membrane. During this laying process, a transmission component converts the rotational motion of the pressure roller into linear motion of a moving component. This moving component drives a flame torch to reciprocate along the axial direction of the pressure roller, allowing the flame torch to dynamically and evenly heat the adhesive on the inside of the membrane. This melts the adhesive and allows it to adhere to the ground substrate, preventing localized overheating that could lead to perforation or uneven adhesive melting. This effectively improves the bonding strength between the membrane and the ground substrate. The waterproof membrane laying device provided by this invention solves the problems of localized overheating leading to burn-through or uneven adhesive melting in existing technologies.

[0008] In one optional embodiment, the moving assembly includes: a housing, a reciprocating screw, a limiting rod, a moving block, and a first drive assembly. The housing is disposed on the mounting frame, and the opening of the housing faces towards the roll material roller. The reciprocating screw is rotatably disposed within the housing and is connected to the transmission assembly. The limiting rod is fixedly disposed within the housing and is parallel to the reciprocating screw. The moving block is sleeved on the reciprocating screw and the limiting rod, and is threadedly connected to the reciprocating screw and slidably connected to the limiting rod. The flame gun is disposed on the moving block.

[0009] Beneficial effects: The housing provides mounting conditions for the movable components on the mounting frame. During the laying of the waterproof membrane, the pressure roller drives the reciprocating screw to rotate through the transmission component. The movable block, threadedly connected to the reciprocating screw, converts the rotational motion of the reciprocating screw into linear motion under the action of the limiting rod. The movable block drives the flame nozzle to move smoothly back and forth along the axial direction of the pressure roller, so that the flame gun can dynamically and evenly bake and heat the adhesive on the inside of the waterproof membrane. The housing is oriented towards the membrane roller, which allows the heat from the flame gun to be concentrated on the waterproof membrane, improving heating efficiency and safety.

[0010] In one optional embodiment, the transmission assembly includes: a first pulley and a first transmission belt, wherein the ends of the reciprocating screw and the pressure roller are each provided with the first pulley, and the first transmission belt is sleeved between the two first pulleys.

[0011] Beneficial effects: During the installation of waterproof membrane, as the trolley is pulled, the friction of the surface of the waterproof membrane drives the pressure roller to rotate. The first pulley at the end of the pressure roller transmits kinetic energy to the first pulley at the end of the reciprocating screw through the first transmission belt. Through the transmission cooperation of the first pulley and the first transmission belt, the pressure roller drives the reciprocating screw to rotate. The reciprocating movement of the flame gun can be realized without a motor or external power supply, reducing manufacturing and operating costs.

[0012] In one alternative embodiment, the mounting frame is movably connected to the trolley, and the mounting frame is provided with an elastic rod. The end of the elastic rod away from the mounting frame is connected to the trolley, and the elastic rod has an elastic force that drives the mounting frame to press the pressure roller toward the ground.

[0013] Beneficial effects: The elastic bar, through the mounting frame, continuously and elastically applies pressure towards the ground to the clamping roller, ensuring that the clamping roller maintains a tight and firm grip on the waterproof membrane even when encountering minor ground undulations, preventing air pockets caused by pressure fluctuations. The elastic bar also acts as a buffer element; when the clamping roller encounters hard protrusions on the ground, the elastic bar can absorb the impact and retract appropriately, protecting the structure of the mounting frame and trolley while preventing rigid compression damage to the waterproof membrane from the clamping roller.

[0014] In one alternative embodiment, the mounting frame is further provided with a vibration assembly for driving the pressure roller to apply vibration to the waterproof membrane.

[0015] Beneficial effects: During the process of compacting the waterproof membrane with the pressure roller, the vibration component transmits the vibration to the pressure roller through the mounting frame. The pressure roller applies high-frequency micro-vibration to the waterproof membrane, which helps to expel residual air from the waterproof membrane and allows the molten adhesive to fill the fine pits in the base layer more fully, further enhancing the adhesion density.

[0016] In one optional embodiment, the vibration assembly includes: a base frame, a rotating rod, a connecting rod, a striking hammer, and a drive assembly. The base frame is disposed on the side of the mounting bracket away from the heating assembly. The rotating rod is rotatably mounted on the base frame. Multiple connecting rods are rotatably disposed on the outer surface of the rotating rod via a torsion shaft. The striking hammer is disposed at the end of the connecting rod away from the rotating rod and is used to strike the bottom of the base frame. The drive assembly is drively connected to the rotating rod and is used to drive the rotating rod to rotate, thereby driving the striking hammer to rotate via the connecting rod.

[0017] Beneficial effects: During the installation of the waterproof membrane, the drive assembly drives the rotating rod to rotate, which in turn drives the hammers to rotate via the connecting rod. Under the action of centrifugal force, multiple hammers continuously strike the base frame, generating vibrations. These vibrations are transmitted to the pressure roller through the mounting frame, causing the pressure roller to apply high-frequency micro-vibrations to the waterproof membrane during compaction. When the hammers impact the surface of the base frame, the torque shaft is stressed, causing the connecting rod to deflect and preventing the hammers from jamming with the base frame. After the hammers finish their impact, the torque shaft resets the connecting rod, allowing the hammers to continue rotating around the rotating rod in preparation for the next impact.

[0018] In one optional embodiment, the drive assembly includes: a second pulley and a second transmission belt, wherein the ends of the rotating rod and the pressing roller are both provided with the second pulley, and the second transmission belt is sleeved between the two second pulleys.

[0019] Beneficial effects: During the installation of waterproof membrane, the second pulley at the end of the pressing roller transmits kinetic energy to the second pulley at the end of the rotating rod through the second transmission belt. Through the transmission cooperation of the second pulley and the second transmission belt, the pressing roller drives the rotating rod to rotate, thus enabling the vibration component to operate without a motor or external power supply.

[0020] In one alternative embodiment, the trolley is provided with an adjustment assembly connected to the elastic rod, the adjustment assembly being used to adjust the vertical height of the mounting frame.

[0021] Beneficial effects: The adjustment component adjusts the height of the mounting frame in the vertical direction and the distance between the pressure roller and the ground substrate to accommodate waterproof membranes of different thicknesses or ground flatness.

[0022] In one optional embodiment, the adjusting assembly includes: a horizontal plate, a lifting screw, and a movable plate. The horizontal plate is fixedly mounted on the vertical frame of the trolley. The lifting screw is rotatably mounted on the horizontal plate, and a rocker wheel is provided at the top end of the lifting screw. Limit sleeves are provided at both ends of the movable plate, and the limit sleeves are slidably mounted on the vertical frame of the trolley. The movable plate is provided with threaded holes that are threadedly connected to the lifting screw. The movable plate is connected to the mounting frame through the elastic rod.

[0023] Beneficial effects: By rotating the lifting screw with the rocker wheel, the movable plate is threadedly connected to the lifting screw. Under the limiting and guiding action of the limiting sleeve, the rotational motion of the lifting screw is converted into the linear motion of the movable plate, so that the movable plate moves up and down along the vertical frame of the trolley, adjusting the height of the mounting frame in the vertical direction, thereby adjusting the distance between the pressing roller and the ground base.

[0024] In one alternative embodiment, the mounting frame is provided with a limiting roller, and a guide gap is provided between the limiting roller and the pressing roller for the waterproof membrane to pass through.

[0025] Beneficial effects: The waterproof membrane passes through the guide gap between the limiting roller and the pressing roller, which can not only regulate the feeding direction of the waterproof membrane, but also help to limit the vertical movement of the waterproof membrane, ensuring that the laying path is straight and reducing the amount of manual correction work.

[0026] In one alternative embodiment, a cleaning brush is provided on the side of the mounting bracket away from the roll material, and the end of the cleaning brush is in contact with the ground.

[0027] Beneficial effects: Between heating and pressing the waterproof membrane, the cleaning brush can pre-clean the surface of the ground substrate of dust or impurities, avoiding problems such as poor adhesion or blistering of the waterproof membrane later due to contamination of the interlayer.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] The following is combined with Figures 1 to 7 The following describes embodiments of the present invention.

[0033] According to an embodiment of the present invention, a waterproof membrane laying device is provided, comprising: a trolley 1, a membrane roller 2, a pressing assembly 3, and a heating assembly 4; the membrane roller 2 is rotatably mounted on the trolley 1 and is used for laying waterproof membrane; the pressing assembly 3 includes a mounting frame 31 and a pressing roller 32, the mounting frame 31 is mounted on the trolley 1, and the pressing roller 32 is rotatably mounted on the mounting frame 31, the central axis of the pressing roller 32 is parallel to the central axis of the membrane roller 2, and the pressing roller 32 is used for laying waterproof membrane. The waterproof membrane is pressed firmly onto the ground. The heating component 4 is located on the side of the mounting frame 31 near the membrane roller 2. The heating component 4 includes a flame gun 41, a moving component 42, and a transmission component 43. The transmission component 43 is located between the moving component 42 and the pressing roller 32. The flame gun 41 is located at the drive end of the moving component 42. The pressing roller 32 drives the moving component 42 through the transmission component 43 to move the flame gun 41 back and forth along the axial direction of the pressing roller 32.

[0034] In use, the waterproof membrane is installed on the membrane roller 2. After the waterproof membrane passes over the pressure roller 32, it is pressed onto the ground substrate by the pressure roller 32. Pulling the trolley 1 moves the membrane, and the friction of the membrane surface drives the pressure roller 32 to rotate, allowing it to roll and lay the membrane. During the laying process, the transmission component 43 converts the rotation of the pressure roller 32 into the linear motion of the moving component 42. The moving component 42 drives the flame gun 41 to reciprocate along the axial direction of the pressure roller 32, so that the flame gun 41 can dynamically and evenly heat the adhesive on the inside of the waterproof membrane, melting it and bonding it to the ground substrate. This prevents localized overheating of the waterproof membrane due to fixed-point heating, which could lead to perforation or uneven melting of the adhesive, effectively improving the bonding strength between the membrane and the ground substrate. The waterproof membrane laying device provided by this invention solves the problems of local overheating of the membrane leading to burn-through or uneven melting of the adhesive in the prior art.

[0035] Specifically, the mounting frame 31 is configured as a portal frame, and the pressure roller 32 is rotatably disposed between the two side plates of the portal frame that are opposite to each other.

[0036] Specifically, the trolley 1 is equipped with rollers at the bottom.

[0037] In one embodiment, the moving component 42 includes: a housing 421, a reciprocating screw 422, a limiting rod 423, a moving block 424, and a first drive component 55. The housing 421 is disposed on the mounting bracket 31, and the opening of the housing 421 is oriented towards the direction close to the roll material 2. The reciprocating screw 422 is rotatably disposed within the housing 421 and is connected to the transmission component 43. The limiting rod 423 is fixedly disposed within the housing 421 and is arranged parallel to the reciprocating screw 422. The moving block 424 is sleeved on the reciprocating screw 422 and the limiting rod 423, and is threadedly connected to the reciprocating screw 422 and slidably connected to the limiting rod 423. The flame gun 41 is disposed on the moving block 424. The cover 421 provides mounting conditions for the movable component 42 on the mounting frame 31. During the laying of the waterproof membrane, the pressure roller 32 drives the reciprocating screw 422 to rotate through the transmission component 43. The movable block 424, threadedly connected to the reciprocating screw 422, converts the rotational motion of the reciprocating screw 422 into linear motion under the action of the limiting rod 423. The movable block 424 drives the flame nozzle to move smoothly back and forth along the axial direction of the pressure roller 32, so that the flame gun 41 can dynamically and uniformly bake and heat the adhesive on the inside of the waterproof membrane. The cover 421 is oriented towards the membrane roller 2, which allows the heat from the flame gun 41 to be concentrated on the waterproof membrane, improving heating efficiency and safety. Alternatively, as an alternative embodiment, the cover 421 can also be a vertical mounting plate.

[0038] Specifically, the cover 421 is configured as a C-shaped plate.

[0039] Specifically, the reciprocating screw 422 has two threaded grooves with the same pitch but opposite directions on its surface. These two grooves are connected by a curve to form a closed helical track. Each threaded groove has a thread or pin embedded in the helical track. When the reciprocating screw 422 rotates, without changing its rotation direction, the side of the helical groove applies a thrust to the moving block 424, causing the moving block 424 to reciprocate along the axial direction.

[0040] In one embodiment, the transmission assembly 43 includes a first pulley 431 and a first transmission belt 432. The reciprocating screw 422 and the pressure roller 32 are both equipped with the first pulley 431 at their ends, and the first transmission belt 432 is sleeved between the two first pulleys 431. During the waterproof membrane laying process, as the trolley 1 is pulled, the friction of the waterproof membrane surface drives the pressure roller 32 to rotate. The first pulley 431 at the end of the pressure roller 32 transmits kinetic energy to the first pulley 431 at the end of the reciprocating screw 422 via the first transmission belt 432. Through the transmission cooperation of the first pulley 431 and the first transmission belt 432, the pressure roller 32 drives the reciprocating screw 422 to rotate. This eliminates the need for a motor and external power supply, enabling the reciprocating movement of the flame gun 41 and reducing manufacturing and operating costs. Alternatively, as an alternative implementation, the transmission assembly 43 can also be configured as a worm gear structure, that is, worm gears are provided at the ends of the reciprocating screw 422 and the pressure roller 32, and the worm gear transmission assembly is disposed between the two worm gears.

[0041] In one embodiment, the mounting frame 31 is movably connected to the trolley 1. An elastic rod 33 is provided on the mounting frame 31, with one end of the elastic rod 33 connected to the trolley 1. The elastic rod 33 has an elastic force that drives the mounting frame 31 to press the pressure roller 32 towards the ground. The elastic rod 33 continuously and elastically provides downward pressure to the pressure roller 32 through the mounting frame 31, ensuring that the pressure roller 32 can always press the waterproof membrane firmly against the ground even when encountering minor undulations, preventing air pockets due to pressure fluctuations. The elastic rod 33 not only provides continuous pressure but also acts as a buffer element. When the pressure roller 32 encounters a hard protrusion on the ground, the elastic rod 33 can absorb the impact and retract appropriately, protecting the structure of the mounting frame 31 and the trolley 1 while preventing rigid compression damage to the waterproof membrane from the pressure roller 32. Alternatively, as an alternative, the mounting frame 31 can also be fixedly connected to the trolley 1.

[0042] Specifically, the elastic rod 33 is configured as a spring rod.

[0043] Specifically, multiple elastic rods 33 are evenly arranged on the top surface of the mounting bracket 31.

[0044] In one embodiment, the mounting frame 31 is further provided with a vibration component 5, which drives the pressure roller 32 to apply vibration to the waterproof membrane. During the process of the pressure roller 32 compacting the waterproof membrane, the vibration component 5 transmits vibration to the pressure roller 32 through the mounting frame 31. The pressure roller applies high-frequency micro-vibration to the waterproof membrane, which helps to expel residual air as the waterproof membrane is laid, and allows the molten adhesive to more fully fill the fine depressions in the substrate, further enhancing the adhesion. Alternatively, as an alternative implementation, the vibration component 5 can be omitted, and a separate vibratory rolling device can be used in conjunction with the waterproof membrane laying device.

[0045] In one embodiment, the vibration assembly 5 includes: a base frame 51, a rotating rod 52, a connecting rod 53, a striking hammer 54, and a drive assembly 55. The base frame 51 is disposed on the side of the mounting bracket 31 away from the heating assembly 4. The rotating rod 52 is rotatably disposed on the base frame 51. Multiple connecting rods 53 are rotatably disposed on the outer surface of the rotating rod 52 via a torsion shaft. The striking hammer 54 is disposed at the end of the connecting rod 53 away from the rotating rod 52, and the striking hammer 54 is used to strike the bottom of the base frame 51. The drive assembly 55 is drively connected to the rotating rod 52, and the drive assembly 55 is used to drive the rotating rod 52 to rotate, thereby driving the striking hammer 54 to rotate via the connecting rod 53. During the installation of the waterproof membrane, the drive assembly 55 drives the rotating rod 52 to rotate. The rotating rod 52 drives the striking hammers 54 to rotate via the connecting rod 53. Under the action of centrifugal force, multiple striking hammers 54 can continuously strike the base frame 51 to generate vibration. The vibration is transmitted to the pressing roller 32 through the mounting frame 31, so that the pressing roller 32 applies high-frequency micro-vibration to the waterproof membrane during the compaction process. When the striking hammers 54 impact the surface of the base frame 51, the torsion shaft is subjected to force, causing the connecting rod 53 to deflect, preventing the striking hammers 54 from getting stuck with the base frame 51. After the impact action of the striking hammers 54 ends, the torsion shaft can reset the connecting rod 53, so that the striking hammers 54 continue to move in a circular motion around the rotating rod 52 with the connecting rod 53, preparing for the next impact. Alternatively, as an alternative implementation, the vibration component 5 can also be equipped with a vertical drive mechanism, which drives the hammer 54 to strike the mounting bracket 31 to generate vibration.

[0046] Specifically, the torque shaft is usually a hinge assembly with a built-in torsion spring, belonging to the category of hinge reset elements.

[0047] In one embodiment, the drive assembly 55 includes a second pulley 551 and a second transmission belt 552. The ends of both the rotating rod 52 and the pressure roller 32 are provided with the second pulley 551, and the second transmission belt 552 is sleeved between the two second pulleys 551. During the laying of the waterproof membrane, the second pulley 551 at the end of the pressure roller 32 transmits kinetic energy to the second pulley 551 at the end of the rotating rod 52 via the second transmission belt 552. Through the transmission cooperation of the second pulley 551 and the second transmission belt 552, the pressure roller 32 drives the rotating rod 52 to rotate, enabling the vibration assembly 55 to operate without a motor or external power supply. Alternatively, as an alternative embodiment, the drive assembly 55 can also be equipped with a motor.

[0048] Specifically, a first pulley 431 is provided at one end of the shaft of the pressure roller 32, and a second pulley 551 is provided at the other end of the shaft. The pressure roller 32 simultaneously drives the reciprocating screw 422 and the rotating rod 52 to rotate, adapting to the working environment where there is no power supply at the construction site. In addition, as an alternative embodiment, the first pulley 431 and the second pulley 551 are arranged sequentially at the same end of the shaft of the pressure roller 32.

[0049] In one embodiment, the trolley 1 is equipped with an adjustment component 34, which is connected to the elastic rod 33. The adjustment component 34 is used to adjust the vertical height of the mounting frame 31. By adjusting the height of the mounting frame 31 in the vertical direction, the adjustment component 34 adjusts the distance between the pressure roller 32 and the ground substrate to accommodate waterproof membranes of different thicknesses or ground flatness. Alternatively, as an alternative embodiment, the adjustment component 34 can be omitted, and the end of the elastic element away from the mounting frame 31 is fixedly connected to the trolley 1.

[0050] In one embodiment, the adjustment assembly 34 includes: a horizontal plate 341, a lifting screw 342, and a movable plate 344. The horizontal plate 341 is fixedly mounted on the vertical frame of the trolley 1. The lifting screw 342 is rotatably mounted on the horizontal plate 341, and a rocker wheel 343 is provided at the top end of the lifting screw 342. Both ends of the movable plate 344 are provided with limit sleeves 345, which are slidably mounted on the vertical frame of the trolley 1. The movable plate 344 is provided with threaded holes that are threadedly connected to the lifting screw 342. The movable plate 344 is connected to the mounting frame 31 through the elastic rod 33. The lifting screw 342 is rotated by the rocker wheel 343. The movable plate 344 is threadedly connected to the lifting screw 342. Under the limiting and guiding action of the limiting sleeve 345, the rotational motion of the lifting screw 342 is converted into the linear motion of the movable plate 344, causing the movable plate 344 to move up and down along the vertical frame of the trolley 1, adjusting the height of the mounting frame 31 in the vertical direction, thereby adjusting the distance between the pressing roller 32 and the ground base. Alternatively, as an alternative embodiment, the limiting sleeve 345 can be omitted, and a limiting groove is provided on the vertical frame of the trolley 1, with protrusions at both ends of the movable plate 344 that slide in conjunction with the limiting groove.

[0051] In one embodiment, the mounting frame 31 is provided with a limiting roller 35, and a guide gap is provided between the limiting roller 35 and the pressing roller 32 for the waterproof membrane to pass through. The waterproof membrane passes through the guide gap between the limiting roller 35 and the pressing roller 32, which not only regulates the feeding direction of the waterproof membrane but also helps to limit its vertical movement, ensuring a straight laying path and reducing the amount of manual correction work. Alternatively, as an alternative embodiment, the limiting roller 35 can be omitted, and the straight laying of the waterproof membrane is maintained by the tension between the pressing roller 32 and the membrane roller 2.

[0052] In one embodiment, a cleaning brush 6 is provided on the side of the mounting bracket 31 away from the roll material roller 2, and the end of the cleaning brush 6 contacts and engages with the ground. Between the heating and pressing of the waterproof membrane, the cleaning brush 6 can pre-clean the surface of the ground substrate of floating dust or impurities, avoiding problems such as poor adhesion or blistering of the waterproof membrane later due to interlayer contamination. Alternatively, as an alternative embodiment, the cleaning brush 6 can be omitted, and the ground substrate can be cleaned manually or with separate cleaning equipment before laying the waterproof membrane.

[0053] How to use: In use, the waterproof membrane is installed on the membrane roller 2. After passing through the guide gap between the limiting roller 35 and the pressing roller 32, the waterproof membrane is pressed under the pressing roller 32. The lifting screw 342 is rotated by the rocker wheel 343. The lifting screw 342 drives the movable plate 344, which is threaded to it, to move downward. The movable plate 344 pushes the mounting frame 31 downward as a whole through the elastic rod 33, so that the pressing roller 32 presses the waterproof membrane firmly on the ground. At this time, the trolley 1 can be pulled to lay the waterproof membrane. During the laying process, the elastic rod 33 always applies downward pressure to the pressing roller 32 to maintain the pressing effect of the pressing roller 32 on the waterproof membrane.

[0054] During the moving and laying process of the waterproof membrane, the friction of the surface of the waterproof membrane drives the pressure roller 32 to rotate. The pressure roller 32 drives the reciprocating screw 422 to rotate through the first transmission belt 432 and the first pulley 431. The reciprocating screw 422 drives the moving block 424 to drive the flame gun 41 to move back and forth, so that the flame gun 41 can dynamically and evenly bake and heat the adhesive on the inside of the waterproof membrane, so that the adhesive melts and adheres to the ground, effectively improving the bonding strength between the waterproof membrane and the ground base.

[0055] Simultaneously, the pressing roller 32 drives the rotating rod 52 to rotate via the second transmission belt 552 and the second pulley 551. The rotating rod 52 drives the striking hammer 54 to rotate via the connecting rod 53. Multiple striking hammers 54 continuously strike the base frame 51 to generate vibration. The vibration is transmitted to the pressing roller 32 through the mounting frame 31. During the compaction process, the pressing roller 32 applies high-frequency micro-vibration to the waterproof membrane, which helps to expel residual air under the waterproof membrane and allows the molten adhesive to more fully fill the fine pits in the base layer, further enhancing the adhesion density.

[0056] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
