Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane laying technology, and in particular to a waterproof membrane laying and fixing device with positioning effect. Background Technology

[0002] In building waterproofing projects, waterproof membranes are widely used in the construction of waterproofing layers on concrete structural surfaces such as roofs and basements due to their excellent waterproofing performance. Currently, the laying and fixing of waterproof membranes often adopts the full-adhesion method or spot-adhesion method. These methods are not only costly in terms of materials and complex in terms of construction, but are also greatly affected by the flatness of the substrate and the ambient temperature, which can easily lead to problems such as hollow areas and water seepage.

[0003] To improve construction efficiency and reliability, mechanical fastening has become an important technical means. Current technologies often involve directly driving fasteners into the substrate and then using pressure plates to secure the roofing membrane. However, this method has significant shortcomings: First, the holes created by the fasteners piercing the membrane become potential water seepage channels, and even with sealant, long-term sealing reliability and durability are difficult to guarantee; second, the single clamping force is prone to stress relaxation or slippage of the membrane under changes in ambient temperature or external loads, affecting the long-term stability of the fastening effect; third, the lack of effective sealing and anchoring between the fasteners and the concrete hole walls allows moisture to penetrate, corroding the fasteners or the substrate and leading to loosening of the fastener.

[0004] Therefore, there is an urgent need in this field for a waterproof membrane laying and fixing device that can achieve efficient and reliable multi-point positioning and fixing, fundamentally solve the problem of sealing the fixing points, and enhance the overall stability of the system. Summary of the Invention

[0005] In order to overcome the shortcomings mentioned in the background art, the present invention provides a waterproof membrane laying and fixing device with positioning effect.

[0006] Technical Solution: A waterproof membrane laying and fixing device with positioning effect includes a positioning rod, an extension plate, a clamping ring, a gasket, a positioning screw, a sealing ring, and a sealing component. The positioning rod is inserted into a pre-drilled slot in the concrete layer. An extension plate is connected to the outer edge of the upper end of the positioning rod, and the extension plate fits against the top surface of the slot. The waterproof membrane is laid on the surface of the concrete layer. The positioning screw penetrates the waterproof membrane and is inserted into the inner cavity of the positioning rod. A gasket and a clamping ring are sequentially fitted on the upper part of the positioning screw. A first threaded groove is machined on the upper part of the inner cavity of the positioning rod, and the positioning screw is threadedly engaged with the first threaded groove. A sealing ring is fixedly connected to the inner cavity of the positioning rod below the first threaded groove, and the sealing ring is sealed with the positioning screw. A sealing component is provided at the lower part of the positioning rod.

[0007] Furthermore, it is particularly preferred that the sealing assembly includes a lifting sleeve and a silicone ring, with the lifting sleeve slidably connected to the lower end of the positioning rod, the inner wall of the lifting sleeve being machined with a second threaded groove, the positioning screw forming a threaded engagement with the second threaded groove, and a silicone ring sleeved on the outer side of the lifting sleeve, the outer surface of the silicone ring being flush with the outer wall of the positioning rod.

[0008] Furthermore, it is particularly preferred that the sealing ring is made of fluororubber.

[0009] In addition, it is particularly preferred that a sealing gasket is included, with an annular sealing gasket embedded at the bottom of the compression ring.

[0010] Furthermore, it is particularly preferred that the extension disc also includes raised rings, with a plurality of raised rings spaced apart along the diametrical direction on the top of the extension disc.

[0011] Furthermore, it is particularly preferred that the device also includes a puncture rod, with the bottom end of the positioning screw connected to the puncture rod.

[0012] Beneficial effects: 1. The device integrates multiple sealing structures. The sealing ring inside the positioning rod seals the micro-gap between it and the positioning screw, and the sealing gasket at the bottom of the clamping ring enhances the sealing performance with the contact surface of the roll material. Together with the dynamic sealing of the sealing component, they form a tight waterproof barrier at the fixing point, ensuring that the waterproof layer is continuous and impermeable.

[0013] 2. This device achieves mechanized multi-point anchoring of waterproof membrane by cooperating with multiple positioning rods and positioning screws pre-installed in the concrete layer. Tightening the positioning screws will press the membrane down evenly through the clamping ring, effectively avoiding the problems of membrane wrinkles, displacement or loose laying that may occur in traditional processes, and significantly improving the flatness of the paving and the reliability of the fixation.

[0014] 3. By screwing in the positioning screw, the lifting sleeve is driven to move upward, squeezing the silicone ring to make it expand radially and tightly fill the gap between the positioning rod and the concrete groove. This structure not only achieves excellent sealing performance, but also provides strong frictional anchoring force, effectively resisting the loosening of the positioning rod caused by external loads or vibrations, and improving long-term stability.

[0022] Example: A waterproof membrane laying and fixing device with positioning effect, such as Figures 1-6 As shown, the assembly includes a positioning rod 4, an extension disc 5, a convex ring 6, a sealing gasket 7, a clamping ring 8, a gasket 9, a positioning screw 10, a piercing rod 11, a sealing ring 12, and a sealing component. Multiple slots 3 are pre-drilled at intervals in the concrete layer 1 according to the installation requirements of the waterproof membrane 2. The positioning rod 4 is inserted into the slots 3. An extension disc 5 is connected to the outer circumferential edge of the upper end of the positioning rod 4, and the extension disc 5 fits against the top surface of the slot 3. The waterproof membrane 2 is laid on the surface of the concrete layer 1. The positioning screw... A piercing rod 11 is connected to the bottom end of the positioning screw 10. The positioning screw 10 pierces the waterproof membrane 2 through the piercing rod 11 and inserts into the inner cavity of the positioning rod 4. A washer 9 and a clamping ring 8 are sequentially fitted on the upper part of the positioning screw 10, with the washer 9 positioned above the clamping ring 8 to enhance the clamping force between the clamping ring 8 and the positioning screw 10. A first threaded groove 15 is machined on the upper part of the inner cavity of the positioning rod 4. The positioning screw 10 is threaded into the first threaded groove 15. By tightening, the clamping ring 8 holds the waterproof membrane 2 in place. Material 2 is pressed against the area around the slot 3 at the corresponding point to achieve multi-point positioning of the waterproof membrane 2. The inner cavity of the positioning rod 4 is fixed with a sealing ring 12 below the first threaded groove 15. After the positioning screw 10 is inserted, it passes through the inner hole of the sealing ring 12. After tightening, the sealing ring 12 fills the micro gap between it and the screw, improving the connection sealing and waterproof performance. The sealing ring 12 is made of fluororubber, which has excellent weather resistance, high temperature resistance and chemical media resistance. It can maintain elasticity and sealing performance for a long time, significantly improving the sealing life and reliability of the fixing point in harsh environments. The lower part of the positioning rod 4 is equipped with a sealing component. The bottom of the clamping ring 8 is embedded with an annular sealing gasket 7. When the clamping ring 8 presses the waterproof membrane 2, the sealing gasket 7 enhances the sealing of the contact interface. The top of the extension disc 5 is provided with multiple convex rings 6 at intervals along the diameter direction. After the waterproof membrane 2 is laid, the convex rings 6 contact its bottom surface, increasing the friction and improving the fixing stability on the concrete layer 1.

[0023] like Figures 2-4 and Figure 6 As shown, the sealing assembly includes a lifting sleeve 13 and a silicone ring 14. The lifting sleeve 13 is slidably connected to the lower end of the positioning rod 4. The inner wall of the lifting sleeve 13 is machined with a second threaded groove 16. The positioning screw 10 and the second threaded groove 16 form a threaded engagement relationship. The silicone ring 14 is sleeved on the outer side of the lifting sleeve 13. The outer surface of the silicone ring 14 is flush with the outer wall of the positioning rod 4. When the positioning screw 10 is screwed into the inner cavity of the positioning rod 4 and continues to push downward, it engages with the second threaded groove 16, driving the lifting sleeve 13 to move upward, squeezing the silicone ring 14 to deform it and tightly fit the inner wall of the slot 3, thereby achieving a sealed connection between the positioning rod 4 and the slot 3, effectively preventing moisture intrusion and loosening of the positioning rod 4.

[0024] When using this device, firstly, according to the design requirements for the installation of the waterproof membrane 2, several slots 3 are drilled at intervals on the concrete layer 1. The positioning rod 4 is inserted into the slot 3, ensuring that the extension plate 5 fits against the top surface of the slot 3. Then, the waterproof membrane 2 is laid on the surface of the concrete layer 1. The gasket 9 and the clamping ring 8 are fitted onto the positioning screw 10. The piercing rod 11 is used to pierce the waterproof membrane 2 and insert into the inner cavity of the positioning rod 4. The positioning screw 10 is screwed on so that it engages with the first threaded groove 15. During the screwing process, the positioning screw 10 passes through the sealing ring 12. Finally, it is tightened so that the clamping ring 8 presses the waterproof membrane 2, and the gasket 9 increases the pressure. The clamping force between the clamping ring 8 and the positioning screw 10, and the sealing gasket 7 enhance the sealing effect between the clamping ring 8 and the roll material. At the same time, the convex ring 6 is embedded in the bottom surface of the waterproof roll material 2, increasing friction to improve the overall stability of the system. As the positioning screw 10 continues to screw in, its bottom end engages with the second threaded groove 16 of the lifting sleeve 13, pushing the lifting sleeve 13 to move upward, squeezing the silicone ring 14 to expand it and press it tightly against the inner wall of the slot 3, thus achieving sealing and anchoring between the positioning rod 4 and the hole wall. When disassembling, the positioning screw 10 is screwed out in the opposite direction, driving the lifting sleeve 13 to move downward, and the silicone ring 14 is released from stress and springs back to its original position, facilitating disassembly.
