Description

Technical Field

[0001] The utility model relates to the technical field of waterproof coiled materials, in particular to an edge sealing structure of a waterproof coiled material. Background Art

[0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc. It is a flexible building material product that can be rolled into a roll to resist the seepage of external rainwater and groundwater. As a leak-free connection between the project foundation and the building, it is the first barrier to waterproofing the entire project and plays a vital role in the entire project.

[0003] In the field of waterproof membrane manufacturing technology at home and abroad, although the existing technology can make the membrane itself have good water resistance, the waterproofing of the joints between different plate structures usually uses sealing gaskets and sealants to seal the edges of the membrane. Although the combination of sealing gaskets and sealants can provide a certain sealing effect in the short term, the sealant may age, shrink or fail over time, resulting in a decrease in sealing performance and a risk of leakage. Therefore, it is necessary to redesign the edge sealing structure of the waterproof membrane to address the above problems. Utility Model Content

The outer walls of the sliders and the inner walls of the connecting grooves are both T-shaped, and the outer walls of the sliders contact the inner walls of the connecting grooves.

[0007] Preferably, a side groove is formed on a side wall of the connection groove, and a skirt is formed on an outer wall of one side of the sliding block.

[0008] Preferably, the outer walls of the two groups of sliders are provided with insertion holes, and the outer wall of the fixed gasket is fixedly connected with two groups of insertion rods, the positions of the two groups of insertion rods correspond to the positions of the sliders, and are inserted into the insertion holes and contact the inner walls of the insertion holes.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4The waterproof membrane edge sealing structure includes two groups of membranes 1 and sealing gaskets 2 and fixing gaskets 3. The sides of the two groups of membranes 1 are provided with fixing grooves 4 and are interconnected. The fixing gaskets 3 are slidably connected inside the fixing grooves 4 and contact the inner walls of the fixing grooves 4. The inner walls of the fixing grooves 4 are provided with connecting grooves 9. Two groups of sliders 8 are fixedly connected below the sealing gaskets 2. The two groups of sliders 8 slide on the inner walls of the connecting grooves 9 respectively. The outer walls of the sliders 8 and the inner walls of the connecting grooves 9 are both T-shaped, and the outer walls of the sliders 8 contact the inner walls of the connecting grooves 9.

[0022] The T-shaped slider 8 and the connecting groove 9 are closely matched to form a continuous mechanical locking structure, which greatly enhances the sealing performance.

[0023] Reference Figure 2 and Figure 4 , a side groove 7 is provided on the side wall of the connecting groove 9, a skirt is provided on one side outer wall of the slider 8, a plug hole 5 is provided on the outer wall of the two groups of sliders 8, two groups of plug rods 6 are fixedly connected to the outer wall of the fixed gasket 3, the positions of the two groups of plug rods 6 correspond to the positions of the slider 8, and are inserted into the inside of the plug hole 5 and contact the inner wall of the plug hole 5;

[0024] The design of the socket 5 and the plug rod 6 improves the connection strength between the slider 8 and the fixed gasket 3, increases the stability of the overall structure, and the plug-in design ensures accurate alignment during installation, prevents structural dislocation, and ensures construction quality.

[0025] The horizontal height of the upper end surface of the sealing gasket 2 is higher than the height of the two sets of coils 1, and the edge of the upper end surface of the sealing gasket 2 is smoothly transitioned. There is a certain gap between the skirt of the slider 8 and the side groove 7. The sealing gasket 2 and the fixed gasket 3 are both made of EPDM rubber material;

[0026] The height of the sealing gasket 2 is higher than the coil 1, which helps water to flow out from the surface of the coil 1 smoothly and prevents water accumulation. The smooth transition reduces the accumulation of dirt and debris at the edge and keeps the coil 1 clean.

[0027] In the utility model, the specific function of the device is: when using the device, spray the sealant on the side groove 7, then splice the two groups of coils 1 together, then align the two groups of sliders 8 at the lower end of the sealing gasket 2 with the connecting groove 9 on the outer wall of the two groups of coils 1, and insert the sealing gasket 2 into the connecting groove 9. At this time, there is a certain gap between the skirts on both sides of the sealing gasket 2 and the side grooves 7. The skirts are pressed downward to make the skirts contact with the side grooves 7. After the initial sealing during the plug-in process, double sealing can be achieved by spraying the sealant and pressing the skirts. The sealant fills the tiny gap, and the pressing of the skirts further ensures the continuity and reliability of the seal. At the same time, the sealant also helps to fill the small gaps that may exist due to material deviations or installation errors, thereby ensuring the overall sealing effect.

[0028] Subsequently, the sealant is sprayed on the inner wall of the fixing groove 4, the fixing gasket 3 is held and aligned with the insertion hole 5, and the provided insertion rod 6 is inserted into the inside of the insertion hole 5 to achieve the connection and fixation between the fixing gasket 3 and the sealing gasket 2 and the two groups of coils 1, forming an overall stable structure, thereby increasing the durability and stability of the system.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
