Description

Technical Field

[0001] This utility model belongs to the field of waterproof construction technology, specifically involving the structural optimization of a waterproof membrane laying device. Background Technology

[0002] In building waterproofing projects, plastic-modified waterproof membranes (such as APP modified bitumen membranes) are widely used. Traditional construction methods typically employ the hot-melt method, which involves heating the membrane and substrate with a flame torch and then pressing them together. This method is not only inefficient, labor-intensive, and poses safety hazards, but the quality of the work is also highly susceptible to the skill level of the workers.

[0003] To address this, some mechanized laying devices have emerged in the existing technology. For example, Chinese patent CN223177159U discloses a waterproof membrane laying device, which automatically releases the membrane via moving wheels and compacts it with pressure rollers, thus improving efficiency to some extent. However, this device has significant drawbacks: firstly, it is only applicable to self-adhesive waterproof membranes with their own adhesive, and cannot solve the construction problem of plastic-modified membranes that require additional application of cold primer or adhesive, thus limiting its application scope.

[0004] Therefore, there is an urgent need for a new type of laying device that can achieve automatic glue application and more flexible laying operation to overcome the shortcomings of the existing technology. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this invention is to provide a plastic-modified waterproof membrane laying device. Through structural optimization, it aims to achieve automatic application of adhesive, thereby significantly improving construction efficiency and quality.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A plastomeric modified waterproof membrane laying device includes a frame, a fixing structure mounted on the frame, a laying structure mounted on the frame, and an adhesive coating structure mounted on the frame; the waterproof membrane is rotatably connected to the fixing structure, and the end of the waterproof membrane is connected to the laying structure and laid along the movement direction of the frame under the guidance of the laying structure; along the laying direction of the waterproof membrane, the adhesive coating structure is located at the front end of the laying structure; The adhesive coating structure includes an adhesive container mounted on the frame, an adhesive nozzle mounted at the lower end of the adhesive container and passing through the frame, and a scraper mounted on the frame; along the laying direction of the waterproof membrane, the adhesive nozzle is located at the front end of the scraper.

[0007] As a further preferred embodiment of the present invention, the glue container includes a container body, a glue outlet disposed at the lower end of the container body and communicating with the glue outlet nozzle, an opening disposed at the upper end of the container body, a piston plate slidably connected to the container body, and a control rod disposed at the upper end of the piston plate and extending through the opening to the outside of the container body.

[0008] As a further preferred embodiment of this invention, there are at least two adhesive coating structures, which are spaced apart along a direction of movement perpendicular to the frame; and a drive crossbar is provided that is connected to the control vertical rods on all the adhesive coating structures.

[0009] As a further preferred embodiment of this invention, it also includes a drive component disposed on the frame and having its output end connected to the drive crossbar to drive the drive crossbar to rise and fall.

[0010] As a further preferred embodiment of the present invention, the glue container further includes a limiting ring disposed on the inner circumference of the opening; the inner diameter of the limiting ring is smaller than the outer diameter of the piston plate.

[0011] As a further preferred embodiment of the present invention, the laying structure includes a strip hole disposed on the frame, a laying roller disposed at the lower end of the frame and located below the strip hole, and a drive motor disposed on the frame for driving the laying roller to rotate.

[0012] As a further preferred embodiment of the present invention, the laying structure further includes a guide strip disposed on the inner sidewall of the long side of the strip hole.

[0013] As a further preferred embodiment of the present invention, the laying structure further includes two fixed frames disposed at the lower end of the frame and arranged opposite to each other, and a tensioning roller connected at both ends to the two fixed frames and located at the upper end of the laying roller.

[0014] As a further preferred embodiment of the present invention, the laying structure further includes a sliding hole disposed on the fixed frame and slidably connected to the roller shaft of the tension roller, an external thread disposed on the roller shaft of the tension roller, and a fixed internal thread ring that matches the external thread and is used to abut against the fixed frame.

[0015] As a further preferred embodiment of this utility model, the inner wall of the sliding hole is provided with a plurality of limiting grooves that are adapted to the roller shaft of the tensioning roller.

[0016] The beneficial effects of this utility model are: The adhesive coating structure provided by this utility model can automatically complete the process of applying adhesive liquid to the base layer before laying the roll material, which perfectly solves the problem that traditional plastic modified roll material cannot be mechanically constructed, and broadens the application range of the equipment.

[0017] The adhesive coating structure provided by this utility model provides a uniform and stable adhesive output. When used with a scraper, it can form an adhesive layer of consistent thickness, effectively ensuring the bonding quality between the roll material and the substrate and overcoming the defects of uneven manual coating.

[0018] The laying structure provided by this utility model uses an independent drive motor to control the unwinding of the waterproof membrane, which makes the movement of the frame and the laying of the membrane two relatively independent actions. Operators can move the frame freely for positioning without releasing the membrane, and can also start or stop laying at any time as needed, greatly improving the flexibility and convenience of construction.

[0026] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, terms such as "set" and "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] As attached Figure 1 Appendix Figure 2 As shown, this embodiment provides a plastic modified waterproof membrane laying device, including a frame 100, a fixing structure 200 disposed on the frame 100, a laying structure 300 disposed on the frame 100, and an adhesive coating structure 400 disposed on the frame 100.

[0028] The frame 100 includes at least a flat plate for mounting the structure, four casters at the lower end of the plate, and a handle on one side of the upper end of the plate. The fixing structure 200 is used to mount the roll formed from the waterproof membrane, and includes at least a support frame and a roll shaft rotatably connected to the support frame for mounting the roll. Pulling the end of the roll causes the roll shaft to rotate on the support frame, thereby unwinding the waterproof membrane. The frame 100 and the fixing structure 200 can directly adopt existing technology, and therefore will not be described in detail.

[0029] The laying structure 300 is mainly installed on the lower surface of the flat plate and is used to guide the waterproof membrane to be laid in a specified direction (the direction of movement of the frame 100). Along the laying direction of the waterproof membrane, the adhesive coating structure 400 is located at the front end of the laying structure 300.

[0030] Specifically, as shown in the attached document Figure 3As shown, the adhesive application structure 400 includes an adhesive container 410 mounted on a frame 100, an adhesive nozzle 420 located at the lower end of the adhesive container 410 and passing through the frame 100, and an adhesive scraper 430 mounted on the frame 100; along the laying direction of the waterproof membrane, the adhesive nozzle 420 is located at the front end of the adhesive scraper 430. The adhesive container 410 is used to hold the adhesive liquid for bonding the waterproof membrane. The specific structure of the glue container 410 includes a container body 4101, a glue outlet 4102 located at the lower end of the container body 4101 and communicating with the glue outlet 420, an opening 4103 located at the upper end of the container body 4101, a piston plate 4104 slidably connected inside the container body 4101, a control rod 4105 located at the upper end of the piston plate 4104 and extending through the opening 4103 to the outside of the container body 4101, and a limiting ring 4106 located on the inner circumference of the opening 4103; the inner diameter of the limiting ring 4106 is smaller than the outer diameter of the piston plate 4104. The glue outlet 4102 can be sealed with an interference fit to the glue nozzle 420. The outer diameter of the piston plate 4104 is approximately the same as the inner diameter of the barrel 4101, thus achieving a sliding and sealed connection between the piston plate 4104 and the barrel 4101. The limiting ring 4106 is mainly used to prevent the piston plate 4104 from being excessively lifted and detached from the barrel 4104. However, to facilitate glue replenishment to the barrel 4101, the limiting ring 4106 can be made of a flexible sealing material, such as rubber, allowing the piston plate 4104 to detach from the barrel 4101 for easy glue replenishment. The outlet of the glue nozzle 420 is close to the ground to guide the glue to a position close to the ground, while the structure of the scraper 430 can refer to existing technology to scrape the flowing glue evenly. For ease of maintenance, the scraper 430 and the frame 100 can be detachably connected by bolts, snap-fit ​​connections, or other detachable methods.

[0031] To ensure effective roll material laying, at least two gluing structures 400 are spaced apart along a direction perpendicular to the frame 100. Multiple dispensing nozzles 420 ensure that the width of the glue after leveling is comparable to the laid width of the roll material, guaranteeing a good laying effect. To facilitate synchronized glue dispensing from the gluing structures 400, a drive crossbar 440 connected to the control vertical rods 4105 on all gluing structures 400 is provided. A drive component 450, mounted on the frame 100 and connected to the drive crossbar 440 at its output end, is also included to raise and lower the drive crossbar 440. The drive component 450 can be a common drive mechanism such as a cylinder, hydraulic cylinder, or electric actuator. The frame 100 should also be equipped with a mobile power supply, controller, solenoid valve, and other common components connected to the drive component 450 to ensure the device is not limited by location and can be used flexibly.

[0032] As some preferred embodiments, see the appendix. Figure 1 and attached Figure 2As shown, the laying structure 300 includes a strip hole 310 disposed on a frame 100, a laying roller 320 disposed at the lower end of the frame 100 and located below the strip hole 310, a drive motor 330 disposed on the frame 100 for driving the laying roller 320 to rotate, and guide strips 340 disposed on the inner sidewall of the long side of the strip hole 310. There are two guide strips 340 arranged symmetrically. The two guide strips 340 can make the strip hole 310 form a V-shape or similar V-shape with a wider upper end and a narrower lower end, thereby facilitating precise guidance of the roll material and preventing it from deviating. The drive motor 330 drives the laying roller 320 to rotate. Compared to the existing technology (CN223177159U) where the roll release and the moving wheel are rigidly mechanically linked, the movement of the frame inevitably leads to roll laying, making it impossible to move the frame independently under no-load conditions (such as for pre-construction positioning or crossing obstacles). This solution can independently control the roll release, thus separating the movement of the frame 100 from the roll laying, improving the flexibility of the device. Furthermore, the drive motor 330 can also be connected to a power supply accessory configured with the drive unit 450. It should be noted that the drive motor 330 and the drive unit 450 are independently controlled. This configuration avoids the use of an additional power source and has the advantages of being economical and compact.

[0033] In some preferred embodiments, the laying structure 300 further includes two fixed frames 350 disposed at the lower end of the frame 100 and arranged opposite to each other, and a tension roller 360 connected at both ends to the two fixed frames 350 and located at the upper end of the laying roller 320. The tension roller 360 is parallel to the laying roller 320, which can both redirect the roll material and improve the tension of the roll material on the laying roller 320, ensuring that the laying roller 320 can effectively drive the unwinding of the roll material.

[0034] Furthermore, as shown in the appendix Figure 4 As shown, the laying structure 300 also includes a sliding hole 370 disposed on the fixed frame 350 and slidably connected to the roller shaft of the tension roller 360, an external thread 380 disposed on the roller shaft of the tension roller 360, and a fixed internal thread ring 390 that matches the external thread 380 and is used to abut against the fixed frame 350. By moving the roller shaft back and forth in the sliding hole 370, the tension of the roll material can be adjusted. By fixing the internal thread ring 390 and the external thread 380 by screwing them together, the position of the roller shaft in the sliding hole 370 can be fixed, thereby ensuring that the tension of the roll material is constant during unwinding, thus ensuring the laying effect of the roll material.

[0035] Furthermore, the inner wall of the sliding hole 370 is provided with a plurality of limiting grooves 3701 that are adapted to the roller shaft of the tension roller 360. The limiting grooves 3701 can cooperate with the roller shaft to provide multiple preset fixing positions, thereby enhancing the stability of the fixing.

[0036] It is understandable that, in order to ensure the cleanliness of the construction substrate, a cleaning brush can be installed at the very front of the moving direction. This is existing technology, so it will not be discussed further.

[0037] The working principle of this device is as follows: During construction, the device is first moved to the starting point. The drive unit 450 is activated, pushing the piston plate 4104 downwards steadily and continuously, squeezing the adhesive from the adhesive container 410 through the dispensing nozzle 420 onto the substrate. As the frame 100 moves forward, the adhesive flows along its path, and the scraper 430 further spreads the adhesive evenly. The drive motor 330 is then activated, rotating the laying roller 320 to smoothly lay the waterproof membrane onto the adhesive-coated substrate. By controlling the speed of the drive motor 330 to match the forward speed of the frame 100, high-quality continuous construction can be achieved. When no-load movement is required, simply turn off the drive motor 330; the movement of the frame 100 will not cause the membrane to be released. When no adhesive application is needed, simply turn off the drive unit 450.

[0038] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
