Description

Technical Field

[0001] This application relates to the field of building construction, and in particular to a waterproof membrane laying device and construction process. Background Technology

[0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, highways, landfills, etc. It is a flexible building material that can be rolled up to resist external rainwater and groundwater seepage. It is the first line of defense for waterproofing the entire project and plays a vital role in the overall project.

[0003] In modern housing construction, roofing membranes are often installed to reduce leaks. Current techniques involve applying adhesive to the ground or the membrane itself before manually rolling it along a baseline. After installation, tools are used to press the membrane to remove air bubbles.

[0004] These processes require the cooperation of multiple workers, are time-consuming and labor-intensive, and the long hours spent bending or squatting to lay the waterproof membrane have a significant impact on the workers' health. Summary of the Invention

[0005] To facilitate the laying of waterproof membrane, this application provides a waterproof membrane laying device and construction process.

[0006] Firstly, this application provides a waterproof membrane laying device, which adopts the following technical solution:

[0007] A waterproof membrane laying device includes a movable frame, a rolling element, an unwinding roller, a liquid leakage assembly, and a coating roller. The rolling element is connected to the lower end of the movable frame. The unwinding roller is rotatably connected to the movable frame about its own axis. The liquid leakage assembly includes a liquid leakage tank, a liquid leakage pipe, and a liquid leakage valve. The liquid leakage tank is connected to the movable frame, the liquid leakage pipe is connected to the liquid leakage tank, and the liquid leakage valve is connected to the liquid leakage pipe and is used to control the opening and closing of the liquid leakage pipe. The coating roller is rotatably connected to the movable frame about its own axis and is located between the unwinding roller and the liquid leakage assembly. The rotation axis of the coating roller is parallel to the rotation axis of the unwinding roller.

[0008] By adopting the above technical solution, the rolling element facilitates the movement of the mobile frame. While the mobile frame moves, the adhesive stored in the leakage tank is opened, the leakage valve is opened, and the adhesive leaks out of the leakage pipe. The spreading roller rolls and pushes the adhesive to make the adhesive evenly distributed. The unwinding roller releases the waterproof membrane, and the waterproof membrane is fixed to the leveling layer by the adhesive. The operation can be completed simply by pushing the mobile frame, which facilitates the laying of the waterproof membrane and improves the laying efficiency.

[0009] Preferably, a waterproof membrane laying device further includes a lifting component, the movable frame is provided with a placement opening, both ends of the coating roller are coaxially fixedly connected to a fixed shaft, the fixed shaft is located inside the placement opening, the lifting component is connected to the inner wall of the placement opening, and the lifting component is used to lift the fixed shaft.

[0010] By adopting the above technical solution, after the waterproof membrane is laid, the lifting component will lift the fixed shaft so that the coating roller cannot contact the ground, reducing the probability of the coating roller sticking to the ground for a long time, and making it easier for the mobile frame to be transferred to the next work location.

[0011] Preferably, the lifting component includes a lifting spring and a lifting plate. One end of the lifting spring is connected to the inner wall facing upwards from the placement opening, and the other end of the lifting spring is connected to the lifting plate. The lifting plate is slidably connected to the inner wall of the placement opening, and the upper end of the lifting plate abuts against the outer wall of the fixed shaft.

[0012] By adopting the above technical solution, the lifting spring supports the support plate and the coating roller. Changing the pressure on the upper part of the support plate can change the height of the coating roller. The placement port guides the sliding of the support plate, which facilitates the stable up and down sliding of the support plate.

[0013] Preferably, a waterproof membrane laying device further includes a limiting plate, the inner wall of the placement opening is provided with a sliding opening, the length direction of the sliding opening is parallel to the axial direction of the fixed shaft, the limiting plate is slidably connected to the inner wall of the sliding opening, the lower end of the limiting plate abuts against the outer wall of the fixed shaft, and the diameter of the fixed shaft increases as it moves away from the coating roller.

[0014] By adopting the above technical solution, during the sliding process of the limiting plate, due to the different diameters of the fixed shafts, the distance from the outer wall of the coating roller to the ground is different. The limiting plate and the lifting spring work together to control the coating roller to contact the ground when pushing the adhesive, and to separate from the ground when the coating roller does not need to push the adhesive.

[0015] Preferably, a waterproof membrane laying device further includes a rotating shaft, a sliding ring, a first hinge rod, and a second hinge rod. The rotating shaft is rotatably connected to a movable frame around its own axis. The rotation axis of the rotating shaft is parallel to the rotation axis of the coating roller. The sliding ring is coaxially slidably sleeved on the outer wall of the rotating shaft. The outer wall of the sliding ring is coaxially provided with an annular groove. The rotating ring is coaxially rotatably embedded in the annular groove. One end of the first hinge rod is hinged to the outer wall of the rotating shaft, and the other end of the first hinge rod is hinged to one end of the second hinge rod. The other end of the second hinge rod is hinged to the outer wall of the rotating ring. The unwinding roller is connected to the rotating shaft through a transmission assembly.

[0016] By adopting the above technical solution, the unwinding roller drives the rotating shaft to rotate through the transmission assembly. During the rotation of the rotating shaft, centrifugal force is generated. The first hinge rod, the second hinge rod, and the rotating ring rotate with the rotating shaft. The centrifugal force causes the first hinge rod and the second hinge rod to expand outward, and the sliding ring to slide, which facilitates the movement of other components through the sliding of the sliding ring.

[0017] Preferably, a waterproof membrane laying device further includes a connecting rod, one end of which is connected to a limiting plate, and the other end of which is connected to a sliding ring.

[0018] By adopting the above technical solution, the sliding ring slides through the connecting rod to drive the limiting plate to slide, thereby realizing automatic control of the contact between the coating roller and the ground. When the unwinding roller rotates, the coating roller contacts the ground. When the unwinding roller does not rotate, the lifting spring resets, causing the coating roller to separate from the ground, and the sliding ring resets. The structure is simple, making it easy to control the up and down sliding of the coating roller in a timely manner, which facilitates the laying of waterproof membrane and improves work efficiency.

[0019] Preferably, a waterproof membrane laying device further includes a rack and a gear, the leakage valve is a ball valve, the valve stem of the leakage valve is coaxially fixedly connected to the gear, the rack is fixedly connected to the sliding ring, and the gear meshes with the rack.

[0020] By adopting the above technical solution, the sliding ring drives the leakage valve to rotate through the rack and gear. When the unwinding roller rotates, the leakage valve opens to release the adhesive. When the unwinding roller stops rotating, the leakage valve closes. This facilitates automatic control of the opening and closing of the leakage valve, makes operation simple, facilitates the laying of waterproof membrane, and improves work efficiency.

[0021] Preferably, the transmission assembly includes a transmission plate, a rotating column, a coupling ring, a first synchronous pulley, a second synchronous pulley, and a synchronous belt. The transmission plate is fixedly connected to the movable frame. The rotating column is rotatably connected to the transmission plate around its own axis. The rotation axis of the rotating column is collinear with the rotation axis of the unwinding roller. One end of the coupling ring is slidably connected to the rotating column, and the other end of the coupling ring is slidably connected to the unwinding roller. The first synchronous pulley is coaxially fixedly connected to the rotating column, and the second synchronous pulley is coaxially fixedly connected to the rotating shaft. The synchronous belt is sleeved on the outer wall of the first and second synchronous pulleys.

[0022] By adopting the above technical solution, it is easy to replace the unwinding roller. When a roll of waterproof membrane is finished, the new unwinding roller is installed on the rotating column through the coupling ring, which facilitates the replacement of the unwinding roller and the laying of waterproof membrane.

[0023] Preferably, the rolling element includes a fixed block and a swivel wheel, the fixed block being fixedly connected to the lower end of the movable frame, and the swivel wheel being fixedly connected to the lower end of the fixed block.

[0024] By adopting the above technical solution, the casters make it easy to move the device to the correct position, making it convenient for staff to handle and use.

[0025] Secondly, this application provides a waterproof membrane construction process, which adopts the following technical solution:

[0026] A waterproof membrane construction process includes the following steps:

[0027] Leveling layer drying test;

[0028] Choose suitable weather for construction;

[0029] Clean the leveling layer;

[0030] Mark the baseline for the roll material application on the leveling layer;

[0031] Basic treatment agent application;

[0032] Enhancement treatment for complex areas;

[0033] Apply adhesive;

[0034] Lay waterproof membrane;

[0035] Compacting and venting of the roll material;

[0036] Treatment of roll material joints.

[0037] By adopting the above technical solutions, cleaning the leveling layer reduces the probability of external debris reducing the sealing performance between the waterproof membrane and the leveling layer; complex reinforcement treatment reduces the probability of house leaks; and the adhesive ensures that the waterproof membrane is stably connected to the leveling layer, further reducing the probability of house leaks.

[0038] In summary, this application includes at least one of the following beneficial technical effects:

[0039] 1. The rolling mechanism facilitates the movement of the mobile frame. As the mobile frame moves, the adhesive stored in the leakage tank is opened, the leakage valve opens, and the adhesive leaks out through the leakage pipe. The spreading roller rolls and spreads the adhesive, ensuring even distribution. The unwinding roller releases the waterproof membrane, which is then fixed to the leveling layer by the adhesive. The operation can be completed simply by moving the mobile frame, making it easy to lay the waterproof membrane and improving laying efficiency.

[0040] 2. The sliding ring slides through the connecting rod to drive the limiting plate to slide, thereby realizing automatic control of the contact between the coating roller and the ground. When the unwinding roller rotates, the coating roller contacts the ground. When the unwinding roller does not rotate, the lifting spring resets, causing the coating roller to separate from the ground, and the sliding ring resets. The structure is simple, which makes it easy to control the up and down sliding of the coating roller in a timely manner, which facilitates the laying of waterproof membrane and improves work efficiency.

[0041] 3. The sliding ring drives the leakage valve to rotate via the rack and gear. When the unwinding roller rotates, the leakage valve opens to release the adhesive. When the unwinding roller stops rotating, the leakage valve closes. This facilitates automatic control of the opening and closing of the leakage valve, making operation simple, convenient for laying waterproof membrane, and improving work efficiency.

[0069] The implementation principle of a waterproof membrane laying device in this application embodiment is as follows: the handle 14 is held to push the moving frame 1 to move. The rolling element 2 makes the moving frame 1 easy to move. During the movement of the moving frame 1, the unwinding roller 31 rotates to release the waterproof membrane. After the waterproof membrane passes over the guide roller 32, it is pressed to the ground by the pressure roller 34. The exhaust plate 41 presses against the upper surface of the waterproof membrane to release air. The unwinding roller 31 drives the rotating shaft 71 to rotate through the transmission component 8. The rotation of the rotating shaft 71 generates centrifugal force. The first hinge rod 75 expands outward so that the sliding ring 72 approaches the fixed ring 74. The sliding ring 72 slides and drives the connecting rod 91 to slide, so that the limiting plate 63 presses down on the fixed shaft 611. The lifting plate 622 slides down and the coating roller 61 contacts the ground. The sliding ring 72 slides so that the rack 92 slides synchronously. The gear 93 meshes and drives the leakage valve 53 to open. When the unwinding roller 31 stops rotating, the reset spring 77 makes the sliding ring 72 reset and the leakage valve 53 close. The lifting spring 621 makes the coating roller 61 separate from the ground.

[0070] This application also discloses a waterproof membrane construction process. The waterproof membrane construction process includes the following steps;

[0071] For the leveling layer drying test, the standard is that the base surface turns white. Spread 1 square meter of the roll material flat and dry on the base surface, let it stand for 3 to 4 hours, then peel it off and check. If there are no watermarks on the base covered area and the roll material, it meets the requirements.

[0072] Choose suitable weather for construction. Construction is prohibited in winds exceeding level 5 or in abnormal weather such as rain or snow. Waterproof membrane construction should be carried out when the temperature is below 0 degrees Celsius.

[0073] Cleaning the leveling layer requires removing all debris, dust, and spilled mortar to prevent affecting the bonding strength between the membrane and the substrate.

[0074] Mark the baseline for the roll material application on the leveling layer;

[0075] Basic treatment agent application;

[0076] For complex areas, additional layers are added at the eaves of the gable wall, downspouts, pipe openings on the roof, gutters, and other flashing areas.

[0077] When applying adhesive, except for the first roll of material at the inside corner where the parapet wall and the base of the wall meet, which must be fully coated with adhesive, leave a 100 mm width uncoated on both the long and short sides of the remaining rolls when applying adhesive.

[0078] Waterproof membrane is laid using a method perpendicular to the roof ridge, depending on the roof slope.

[0079] Compacting and venting of the roll material;

[0080] Treatment of roll material joints, cleaning of dust from the ends of the roll material, bonding and sealing of the ends.

[0081] The implementation principle of the waterproof membrane construction process in this application embodiment is as follows: the three steps of applying adhesive, laying waterproof membrane, and membrane pressure venting are completed simultaneously using a waterproof membrane laying device, which improves the laying efficiency.

[0082] 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.
