Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane technology, and in particular to a high-durability, root-penetration-resistant PVC waterproof membrane. Background Technology

[0002] Waterproof membrane is a material widely used in building waterproofing projects. It plays a vital role in preventing building leaks and is an important component of building materials. It is mainly used in building walls, roofs, tunnels, highways, landfills, etc. Root penetration resistant waterproof membrane is placed between the planting soil and the roof structure, providing a dual guarantee of preventing plant roots from penetrating and waterproofing.

[0003] However, existing waterproof membranes do not have snap-fit ​​functionality on their sides. They are usually joined by cold bonding or hot fusion. Sun and rain can corrode the joints of adjacent membranes, leading to water seepage. Therefore, a high-durability, root-penetration-resistant PVC waterproof membrane is proposed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the above-mentioned traditional technologies and provide a highly durable, root-penetration-resistant PVC waterproof membrane.

[0005] The objective of this utility model is achieved through the following technical measures:

[0006] A high-durability, root-penetration-resistant PVC waterproof membrane includes a membrane body, the membrane body includes an abrasion-resistant layer, a PVC base layer is provided on top of the abrasion-resistant layer, a root-penetration-resistant layer is provided on top of the PVC base layer, an ultraviolet protection layer is provided on top of the root-penetration-resistant layer, and an edging is provided on the outside of the membrane body, with a first mounting plate and a second mounting plate fixedly provided on the edging.

[0007] As a further description of the above technical solution: the top of the roll body is provided with multiple water-blocking strips, and two adjacent water-blocking strips form a water guide channel.

[0008] As a further description of the above technical solution: the bottom of the wear-resistant layer is provided with anti-slip texture, and the depth of the anti-slip texture is one centimeter.

[0009] As a further description of the above technical solution: the bottom of the first mounting plate is provided with multiple insertion holes and slots, and the top of the second mounting plate is fixedly provided with multiple insertion rods and clips.

[0010] As a further description of the above technical solution: the insertion hole is provided with a first protrusion, and the insertion rod is provided with a second protrusion on the outside.

[0011] As a further description of the above technical solution: the first mounting plate, the second mounting plate, the first protrusion, the second protrusion, the locking strip and the insertion rod are all made of rubber, the locking strip and the locking groove are adapted to each other, and the insertion rod and the insertion hole are adapted to each other.

[0012] As a further description of the above technical solution: the thickness of the edging is five millimeters, and the edging is made of rubber.

[0013] This utility model has the following beneficial effects:

[0014] By setting up a first mounting plate, a second mounting plate, insertion holes, a first protrusion, a insertion rod, a second protrusion, a locking strip, and a locking groove, during installation, multiple insertion holes are fitted onto multiple corresponding insertion rods, the locking groove is aligned with the locking strip, and then the first mounting plate is pressed down so that the locking strip is inserted into the locking groove. The first and second protrusions contact each other, and the second protrusion slides above the first protrusion. After installation, the first and second mounting plates are attached. The cooperation of the insertion rod and insertion hole can achieve the initial positioning of the first and second mounting plates, and the cooperation of the locking groove and locking strip can achieve secondary positioning and sealing functions, which can effectively prevent water seepage at the splice of adjacent rolls. By setting the edge binding, not only can the edge strength be guaranteed and the roll be prevented from being torn, but the waterproof performance of the roll can also be optimized. The setting of multiple water-blocking strips can form multiple water guiding channels, which can efficiently collect and guide the water accumulated on the surface of the roll. When rainfall or other water accumulation occurs, the water will flow quickly into the water guiding channel along the slope of the roll, instead of accumulating or spreading on the surface of the roll. This effectively prevents water from soaking the membrane for extended periods, avoiding aging and damage caused by water erosion, thus extending the service life of the waterproof membrane.

Detailed Implementation

[0019] Example: Refer to Figures 1 to 3This utility model provides a high-durability, root-penetration-resistant PVC waterproof membrane: it includes a membrane body 1, a wear-resistant layer 2, and anti-slip texture 15 at the bottom of the wear-resistant layer 2, the depth of which is one centimeter. A PVC base layer 3 is provided on top of the wear-resistant layer 2, a root-penetration-resistant layer 4 is provided on top of the PVC base layer 3, and an ultraviolet protection layer 5 is provided on top of the root-penetration-resistant layer 4. The ultraviolet protection layer 5 can effectively absorb and reflect ultraviolet rays, preventing the membrane from aging and degrading due to ultraviolet radiation, and significantly improving the weather resistance and durability of the membrane. The outer side of the membrane body 1 is provided with an edge banding 7, the thickness of which is five millimeters, and the edge banding 7 is made of rubber.

[0020] To prevent water seepage at the joints, a first mounting plate 8 and a second mounting plate 9 are fixedly mounted on the edging 7. The bottom of the first mounting plate 8 has multiple insertion holes 10 and slots 16, while the top of the second mounting plate 9 has multiple insertion rods 12 and locking strips 14. Each insertion hole 10 has a first protrusion 11, and each insertion rod 12 has a second protrusion 13. The first mounting plate 8, second mounting plate 9, first protrusion 11, second protrusion 13, locking strips 14, and insertion rods 12 are all made of rubber. The locking strips 14 and slots 16 are compatible, and the insertion rods 12 and insertion holes 10 are compatible. During assembly, the multiple insertion holes 10 are... The first mounting plate 8 is then pressed down onto the corresponding insert rods 12, aligning the slots 16 with the strips 14. The first mounting plate 8 is then pressed down, causing the strips 14 to lock into the slots 16. The first protrusion 11 and the second protrusion 13 come into contact, and the second protrusion 13 slides above the first protrusion 11. After installation, the first mounting plate 8 and the second mounting plate 9 fit together. The cooperation between the insert rods 12 and the insertion holes 10 enables the initial positioning of the first mounting plate 8 and the second mounting plate 9. The cooperation between the slots 16 and the strips 14 enables secondary positioning and sealing, effectively preventing water seepage at the joints of adjacent rolls.

[0021] To improve water conductivity, the top of the membrane body 1 is equipped with multiple water-retaining strips 6. Adjacent water-retaining strips 6 form water-guiding channels, which can efficiently collect and guide water accumulated on the surface of the membrane. When rainfall or other water accumulation occurs, the water will quickly flow into the water-guiding channels along the slope of the membrane, instead of accumulating or spreading on the surface of the membrane. This can effectively prevent water from soaking the membrane for a long time, avoid aging and damage to the membrane due to water erosion, and thus extend the service life of the waterproof membrane.

[0022] Working principle: When laying the waterproof membrane, the first roll is laid on the surface. When laying the second roll, multiple insertion holes 10 are fitted onto the corresponding insertion rods 12, aligning the slots 16 with the clips 14. Then, the first mounting plate 8 is pressed down, causing the clips 14 to engage with the slots 16. The first protrusion 11 and the second protrusion 13 come into contact, and the second protrusion 13 slides above the first protrusion 11. After installation, the first mounting plate 8 and the second mounting plate 9 are fitted together, and the engagement of the insertion rods 12 and the insertion holes 10 achieves the desired effect. The initial positioning of the first mounting plate 8 and the second mounting plate 9, along with the cooperation of the slot 16 and the strip 14, enables secondary positioning and sealing, effectively preventing water seepage at the joints of adjacent membrane rolls. The rubber edging 7 allows for deformation under different environments while maintaining edge strength. The UV protection layer 5 effectively absorbs and reflects ultraviolet rays, preventing the membrane from aging and degrading due to UV radiation, significantly improving the membrane's weather resistance and durability. Multiple water-blocking strips 6 form multiple water channels, efficiently collecting and guiding water accumulation on the membrane surface. In the event of rainfall or other water accumulation, water will quickly flow into the water channels along the slope of the membrane, rather than accumulating or spreading on the surface. This effectively prevents prolonged immersion of the membrane in water, avoiding aging and damage due to water erosion, thereby extending the service life of the waterproof membrane.
