Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane installation technology, specifically a waterproof membrane suspension and fixing device. Background Technology

[0002] Waterproof membrane is a type of sheet material made from polymer materials using advanced manufacturing processes to prevent liquid leakage and gas evaporation. It plays a crucial role in engineering fields such as construction, water conservancy, and transportation. It effectively prevents groundwater and rainwater from seeping into the internal structure of a project, avoiding damage due to long-term water erosion and thus ensuring the durability and safety of the project. For example, in underground engineering, waterproof membranes prevent groundwater from seeping into underground building spaces, ensuring a dry interior and providing a good environment for personnel activities and equipment operation. In water conservancy projects, waterproof membranes can be used in dams, canals, and other structures to prevent water leakage and ensure the normal operation and stability of water conservancy facilities.

[0003] In practical engineering applications, waterproof membranes cannot be directly laid on the base surface in many scenarios and need to be installed by suspension. For example, in tunnel construction, the tunnel wall surface is irregular, and to meet the space requirements of subsequent construction and ensure waterproofing effectiveness, the waterproof membrane needs to be kept at a certain distance from the tunnel wall. Suspension allows the waterproof membrane to be laid flat in the designed position, forming a continuous and closed waterproof barrier. In the construction of underground utility tunnels, to facilitate pipe installation and maintenance while ensuring waterproofing effectiveness, the waterproof membrane also needs to be suspended and fixed in a suitable position on the tunnel wall. In addition, some special building structures or complex terrain conditions also require the waterproof membrane to be installed by suspension to ensure that it fits tightly against the structural surface and fully exerts its waterproofing function.

[0004] According to the search, Chinese patent document CN208236443U discloses a tunnel composite waterproof membrane suspension and fixing device. The composite waterproof membrane has a strap on the back, and the other end of the strap is fixed to the shotcrete structure. A positioning groove is opened inside the shotcrete structure, and a hanger is embedded in the positioning groove. A hanging ring is provided on the side of the hanger near the strap, and the strap is tied and fixed to the hanging ring.

[0005] The aforementioned patent documents disclose a method for suspending and fixing waterproof membranes by adding hangers and connecting them with straps. However, in actual use, the binding connection requires individual operation, involves many operation points, is cumbersome, and has low construction efficiency. Furthermore, the binding is prone to loosening due to external forces, affecting the connection effect. Therefore, how to achieve a firm connection and improve construction efficiency are urgent problems to be solved. Utility Model Content

[0027] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0028] Figures 1-9 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-9 The present invention will be further described below.

[0029] See attached document Figures 1-9 This utility model discloses a waterproof membrane suspension and fixing device, including a waterproof membrane 1, geotextile 3, and self-adhesive tape 2, and further including: connecting strips 4, which are arranged in a linear array along the outer wall of the waterproof membrane 1, and connecting boxes 5 are snapped onto the connecting strips 4 and inserted into the concrete layer; the connecting boxes 5 are symmetrically arranged at both ends inside the connecting boxes 5 for clamping and limiting the connecting strips 4, and the limiting structures include two symmetrically arranged locking blocks 14, with torsion springs 15 fixed on both sides of the locking blocks 14; it also includes a pushing component, which pushes... The moving part is used to push the card block 14 to rotate it; the connecting box 5 is also symmetrically arranged with locking structures for blocking and locking the card block 14. The locking structure includes a moving frame 9, a plug-in part and a locking part. The moving frame 9 pushes the plug-in part and the locking part to limit the card block 14. The self-adhesive tape 2 is fixed on the outside of the waterproof membrane 1 and there are multiple linear arrays. The geotextile 3 is set on the inside of the tunnel. The self-adhesive tape 2 is adhered to the surface of the geotextile 3. The geotextile 3 has through holes that are compatible with the connecting box 5.

[0030] Specifically, the connecting strip 4 is fixed to the outer wall of the waterproof membrane 1, the connecting box 5 has a groove adapted to the connecting strip 4, and multiple connecting rods 6 are fixed to the rear side of the connecting box 5. The connecting box 5 and the connecting rods 6 are embedded in the tunnel concrete layer. The connecting strip 7 is fixed above and below the connecting strip 4, and the locking strip 7 is locked into the groove.

[0031] In this embodiment, the connecting rod 6 and the connecting box 5 are embedded in the concrete layer of the tunnel for subsequent connection. When in use, the connecting strip 4 and the locking strip 7 are locked into the groove. The connection between the locking strip 7 and the groove is used to further limit the connection of the connecting strip 4 and improve the connection effect between the connecting strip 4 and the groove.

[0032] Specifically, one end of the locking block 14 is locked onto the connecting strip 4, and the connecting strip 4 has a locking groove adapted to the locking block 14; the pushing component includes a connecting frame 17, a stop block 16, and a protruding plate 18. The connecting frame 17 is horizontally arranged in a T-shape. The longer end of the connecting frame 17 is located outside the two stops 16 away from the end of the connecting strip 4. The stops 16 are symmetrically fixed above and below the longer end of the connecting frame 17. When the locking block 14 is not locked onto the connecting strip 4, the stops 16 abut against the locking block 14. The middle part and the shorter end of the connecting frame 17 are located between the upper and lower locking blocks 14. There are two protruding plates 18, which are symmetrically fixed above and below the middle part of the connecting frame 17. The shorter end of the connecting frame 17 extends into the groove; the limiting structure also includes two vertically symmetrically arranged fixing frames 19. The two fixing frames 19 are symmetrically arranged outside the middle part of the connecting frame 17 above and below, and are located between the two locking blocks 14.

[0033] In this embodiment, the fixing frame 19 is used in conjunction with the protruding plate 18 to limit the movement range of the connecting frame 17 when the connecting frame 17 moves horizontally. The shorter end of the connecting frame 17 extends into the groove, so that when the connecting strip 4 is stuck in the groove, it squeezes the connecting frame 17, causing the connecting frame 17 to move. The stop block 16 squeezes the locking block 14, causing the locking block 14 to rotate toward the stop block 16 until the stop block 16 and the locking block 14 separate. Under the action of the torsion spring 15, the locking block 14 resets and is stuck in the slot, limiting the movement of the connecting strip 4.

[0034] Specifically, the movable frame 9 includes a horizontal plate and a linear array of rods on the side near the connecting bar 4. The movable frame 9 is slidably connected to a mounting frame 8, which is fixed inside the connecting box 5. The plug-in component includes a plug rod 10 and a plug block 11. The plug rod 10 is fixed on the side of the horizontal plate away from the rod, and the plug block 11 is fixed on the mounting frame 8. The plug rod 10 is inserted into the plug block 11. The locking component includes a crank rod 12 and a baffle 13. One end of the crank rod 12 is hinged to one end of the baffle 13. The other end of the baffle 13 passes through the mounting frame 8 and extends between the locking block 14 and the stop block 16. The other end of the crank rod 12 is hinged to the horizontal plate.

[0035] In this embodiment, the horizontal plate and the rod are an integral structure. The rod extends to the outside of the connecting box 5. When the locking structure is not in use, the insertion rod 10 is not connected to the insertion block 11, and the insertion block 11 does not have an insertion hole. The insertion block 11 is made of wood, and the baffle 13 is not moved between the stop block 16 and the locking block 14. When in use, the rod is hammered from the outside of the waterproof plate 1, so that the insertion rod 10 is inserted into the insertion block 11. The horizontal plate moves, and the baffle 13 is pushed horizontally by the curved rod 12. The baffle 13 moves between the locking block 14 and the stop block 16, locking and limiting the locking block 14, ensuring that the locking block 14 limits the connection of the connecting strip 4, thereby ensuring the connection effect between the connecting strip 4 and the connecting box 5, realizing the suspension and fixation of the waterproof plate 1, and preventing it from falling off.

[0036] In use, the connecting box 5 and the connecting rod 6 are embedded into the tunnel concrete layer. Then, the geotextile 3 is installed. When installing the waterproof membrane 1, the self-adhesive tape 2 is attached to the geotextile 3 to pre-install the waterproof membrane 1. Then, a hammer is used to tap the connecting strip 4 from the inside of the waterproof membrane 1, so that the connecting strip 4 and the locking strip 7 are locked into the groove. During the tapping process, the connecting strip 4 squeezes the connecting frame 17, so that the stop block 16 and the locking block 14 are separated. Under the action of the torsion spring 15, the locking block 14 retracts and is locked into the slot on the connecting strip 4. Then, the rod body is tapped, so that the horizontal plate drives the insertion rod 10 to move. The insertion rod 10 is inserted into the insertion block 11. At the same time, the curved rod 12 pushes the baffle 13 to move horizontally. The baffle 13 moves between the locking block 14 and the stop block 16 to lock and limit the locking block 14. When the rod body is completely moved into the connecting box 5, the same operation is performed on the other multiple connecting strips 4 to achieve the suspension and fixation of the waterproof membrane 1.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
