Description

Technical Field

[0001] This application relates to the technical field of roof waterproofing, and more specifically, to a roof waterproofing membrane fixing structure. Background Technology

[0002] Roofing waterproof membrane is the core material of roofing waterproofing projects. Its core function is to form a sealed waterproof layer through continuous laying to prevent rainwater penetration. According to the material, it can be divided into two main types: modified bitumen type and polymer type, which are suitable for different roof scenarios and waterproofing needs. Waterproof membrane is usually laid by hot melt method, which is operated by flame spray gun. The spray gun is 50-100mm away from the membrane and heats it at a uniform speed to melt the bitumen layer (to a glossy black color) and avoid scorching the membrane. One person pushes the roll and another person simultaneously compacts it to ensure that there are no air bubbles between the membrane and the base layer and the overlapping edges (rolling from the middle to both sides).

[0003] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: Existing hot-melt methods for laying waterproof membranes are prone to improper heating control. Overheating can lead to excessively high spray gun temperatures, causing carbonization and aging of the membrane's bitumen base material, resulting in loss of elasticity and subsequent cracking and leakage. Insufficient heating results in the bitumen layer not fully melting, leading to poor adhesion to the substrate or overlaps, creating hollow areas and loose bonding, allowing rainwater to easily seep in through gaps. Uneven heating causes localized scorching and incomplete melting, resulting in inconsistent membrane shrinkage, wrinkles, or poor sealing of overlaps. The hot-melted waterproof membrane cannot adhere tightly to the roof, easily leading to leaks and increased roof maintenance costs. Utility Model Content

A fixing plate is fixedly installed on the outside of the threaded sleeve through a connecting rod. Fixing rods are fixedly installed at both ends of the fixing plate through pads. A pressure hub is rotatably installed at the end of the fixing rod away from the fixing plate through a rotating rod.

[0007] Optionally, two identical sliding plates are fixedly installed on both sides of the middle of the vertical strip.

[0008] Optionally, two identical sliding rods are fixedly installed on both sides of the threaded sleeve. The sliding rods are O-shaped, and the side of the sliding rod away from the threaded sleeve is slidably inserted into the middle of the end of the base plate. The width of the threaded sleeve is smaller than the width of the power groove in the middle of the end of the base plate.

[0009] Optionally, the bottom of the lead screw is rotatably equipped with a bottom bracket, the top of which is fixedly mounted on the bottom of the base plate, and the bottom of the bottom bracket is higher than the lowest point of the pressure wheel hub.

[0010] Optionally, a first hydraulic rod is fixedly mounted on the middle of the upper surface of the base plate via a pad. A first limiting plate is fixedly mounted on the top of the first hydraulic rod. A transverse moving plate is fixedly mounted on the bottom of the first limiting plate.

[0014] In summary, this application includes the following beneficial technical effects: 1. This utility model, by setting up components such as a second hydraulic rod, vertical strips and retractable liquefied gas pipes, allows for flexible adjustment of the heating range by sliding a slide plate in the middle of the front track frame. This avoids localized scorching or incomplete melting, ensuring uniform melting of the asphalt layer of the roll material. It is suitable for roll materials of different widths, and the overlapping edges can be targeted for enhanced heating. This solves the problem of traditional handheld spray guns "missing some areas while focusing on others," and improves the bonding strength.

[0015] 2. This utility model incorporates components such as a lead screw, threaded sleeve, fixing plate, and pressure wheel hub. The pressure wheel hub rolls on the surface of the hot-melted waterproof membrane, ensuring that the gravity roller closely follows the hot-melt gun. This immediate compaction after heating prevents the adhesion from failing after the asphalt cools, reducing voids and loose adhesion from the source. The adjustable roller can adapt to different substrate flatness and membrane thickness, maintaining uniform pressure to ensure a tight fit between the membrane and the substrate. The arc-shaped support plate provides smooth support for the membrane, reducing friction during installation and allowing the membrane to unfold naturally, avoiding wrinkles caused by pulling. The integrated design reduces the need for multiple actions such as holding the spray gun, holding the roll, and compacting, lowering labor intensity and allowing even beginners to quickly get started.

[0020] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0021] The following is in conjunction with the appendix Figure 1 To be continued Figure 6 This application will be described in further detail.

[0022] This application discloses a roof waterproofing membrane fixing structure. For example... Figures 1 to 6 As shown, the system includes a base plate 1. A first hydraulic rod 11 is fixedly mounted on the middle of the upper surface of the base plate 1 via a pad. A first limiting plate 10 is fixedly mounted on the top of the first hydraulic rod 11. A transverse moving plate 3 is fixedly mounted on the bottom of the first limiting plate 10. Three identical vertical shafts 24 are fixedly mounted on the bottom of the transverse moving plate 3. An arc-shaped support plate 25 is fixedly mounted on the bottom of the vertical shafts 24. The outer side of the vertical shafts 24 is slidably inserted into the through hole in the middle of the base plate 1. A push handle 8 is fixedly mounted on the end of the upper surface of the base plate 1. Two identical extension plates 4 are fixedly mounted on both sides of the end of the base plate 1. A push handle 8 is fixedly mounted on the bottom of the extension plates 4. Three identical traveling wheels drive the first limiting plate 10 and the lower transverse moving plate 3 to move via the first hydraulic rod 11, thus activating the effect of adjusting the height of the arc-shaped support plate 25. When not in use, the arc-shaped support plate 25 can be retracted. The traveling wheels at the bottom ensure that the device can move to adapt to more working positions. The arc-shaped support plate 25 is set as a quarter circle arc, and the lowest point of the arc-shaped support plate 25 is horizontal with the lowest point of the pressure wheel hub 6. The bottom of the arc-shaped support plate 25 and the pressure wheel hub 6 are set at the same level to facilitate the compaction of the hot-melted waterproof membrane during movement, avoiding the failure of adhesion after the asphalt cools down, and reducing hollowness and loose adhesion from the source.

[0023] A front track frame 2 is fixedly installed at the front end of the bottom of the base plate 1. Two identical sliding grooves 22 are fixedly installed at the bottom of the inner wall of the front track frame 2. The inner wall of the sliding groove 22 is slidably connected to the bottom of the pulley frame 18. The sliding groove 22 is designed to prevent the pulley at the bottom of the pulley frame 18 from shifting during movement, making the vertical bar 17 in the middle move more stably. A sliding groove 22 is fixedly installed at the middle position of the bottom of the front track frame 2. A vertical bar 17 is slidably installed on the inner wall of the sliding groove 22. Two identical sliding plates 16 are fixedly installed on both sides of the middle of the vertical bar 17. The sliding plates 16 are "C" shaped and their inner walls are slidably fitted onto the upper and lower sides of the bottom of the front track frame 2. The width of the vertical bar 17 is smaller than the width of the sliding groove 22. A pulley frame 18 is fixedly installed at the top of the vertical bar 17. The bottom of the pulley frame 18 is slidably installed on the bottom of the inner wall of the front track frame 2 via pulleys. The vertical bar 17 is connected to the second hydraulic rod 1. The vertical bar 17 moves left and right under the action of 9, and at the same time drives the slide plate 16 to slide on the surface of the slide groove 22. Under the action of the slide plate 16, the vertical bar 17 can slide smoothly. The pulley frame 18 slides inside the front track frame 2 through the pulley at the bottom, ensuring that the vertical bar 17 can slide at a uniform speed. The bottom of the vertical bar 17 is fixedly provided with a nozzle 21. The middle of the nozzle 21 is connected to a liquefied gas pipe 20. The top of the liquefied gas pipe 20 extends to the upper part of the middle of the base plate 1. The liquefied gas pipe 20 is composed of a retractable corrugated pipe. The liquefied gas pipe 20 is connected to the external liquefied gas, so that the nozzle 21 sprays the material towards the bottom of the waterproof membrane. The vertical bar 17 drives the nozzle 21 to move, adapting to more hot-melt positions. A second hydraulic rod 19 is fixedly provided on one side of the top of the vertical bar 17. The end of the second hydraulic rod 19 away from the vertical bar 17 is fixedly provided to one end of the bottom of the inner wall of the front track frame 2 through a connecting plate.

[0024] A second limiting plate 12 is fixedly installed at the middle position of the upper surface of the end of the base plate 1. A lead screw 9 is rotatably installed at the middle position of the top of the second limiting plate 12. A bottom bracket 14 is rotatably installed at the bottom of the lead screw 9. The top of the bottom bracket 14 is fixedly installed at the bottom of the base plate 1. The bottom position of the bottom bracket 14 is higher than the lowest point of the bottom of the pressure hub 6. The bottom bracket 14 is located at the bottom of the lead screw 9 and provides support for the lead screw 9, ensuring that the lead screw 9 can rotate smoothly. A threaded sleeve 13 is threadedly connected to the middle of the lead screw 9. Two identical sliding rods 15 are fixedly installed on both sides of the threaded sleeve 13. The rod 15 is set in an "O" shape. The side of the sliding rod 15 away from the threaded sleeve 13 is slidably inserted into the middle of the end of the base plate 1. The width of the threaded sleeve 13 is smaller than the width of the power groove 23 in the middle of the end of the base plate 1. The threaded sleeve 13 moves under the action of the lead screw 9 and slides up and down at the end of the base plate 1 through the "O" shaped sliding rod 15 to prevent the threaded sleeve 13 from rotating with the lead screw 9. A fixing plate 7 is fixedly installed on the outside of the threaded sleeve 13 through a connecting rod. Fixing rods 5 are fixedly installed at both ends of the fixing plate 7 through pads. A pressure hub 6 is rotatably installed at the end of the fixing rod 5 away from the fixing plate 7 through a rotating rod.

[0025] The implementation principle of the roof waterproof membrane fixing structure in this application embodiment is as follows: the device can move as a whole through the walking wheels at the bottom of the extension plates 4 on both sides of the end of the base plate 1, adapting to different construction positions; the push handle 8 makes it easy for the operator to push the device to adjust the work point, meeting the construction needs of different areas of the roof. When the first hydraulic rod 11 in the middle of the upper surface of the base plate 1 is activated, it drives the first limiting plate 10 at the top and the horizontal moving plate 3 below to move up and down. The horizontal moving plate 3 drives the arc-shaped support plate 25 to move synchronously through the vertical shaft 24. During this process, the height of the arc-shaped support plate 25 can be adjusted, and it can be retracted when not in use. The arc-shaped support plate 25 is set as a quarter circle arc, and its lowest point is kept horizontal with the lowest point of the pressure wheel hub 6, providing smooth support for the roll material, reducing friction during laying, ensuring that the roll material unfolds naturally, and avoiding wrinkles caused by pulling. The groove 22 at the bottom of the inner wall of the front track frame 2 restricts the movement trajectory of the bottom pulley of the pulley frame 18 to prevent deviation. When the second hydraulic rod 19 extends or retracts, it drives the vertical strip 17 to move left and right along the groove 22 at the bottom of the front track frame 2. At the same time, the "C"-shaped sliding plates 16 on both sides of the vertical strip 17 slide along the upper and lower sides of the bottom of the front track frame 2. This, combined with the sliding of the bottom pulley of the pulley frame 18 at the bottom of the inner wall of the front track frame 2, ensures that the vertical strip 17 moves smoothly and at a constant speed. The nozzle 21 at the bottom of the vertical strip 17 moves synchronously with it. The nozzle 21 is connected to the external liquefied gas through a liquefied gas pipe 20 made of a retractable corrugated pipe. The liquefied gas is sprayed out as a flame through the nozzle 21 to heat melt the bottom of the waterproof membrane. By adjusting the left and right position of the nozzle 21, it can flexibly adapt to membranes of different widths and heat the overlapping edges in a targeted manner to ensure that the asphalt layer of the membrane melts evenly and avoids local scorching or incomplete melting. Rotating the screw 9 at the top of the second limiting plate 12 causes the bottom of the screw 9 to rotate on the bottom frame 14. As the screw 9 rotates, the threaded sleeve 13, connected in the middle, moves up and down along the screw 9 under the constraint of the "O"-shaped sliding rod 15. The threaded sleeve 13 drives the fixing plate 7 and the fixing rods 5 at both ends to move synchronously via the connecting rod. The pressure hub 6 at the end of the fixing rod 5 adjusts its height according to the fixing plate 7. The pressure hub 6 closely follows the hot-melt nozzle 21, immediately rolling and compacting the surface of the roll material after hot melting, using gravity to ensure a tight bond between the roll material and the base layer. By adjusting its height, the pressure hub 6 can adapt to different base layer flatness and roll material thicknesses, preventing adhesion failure after asphalt cools and reducing hollow areas and loose adhesion from the source.
