Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane technology, specifically a spliced ​​waterproof membrane. Background Technology

[0002] Waterproof membrane is a seepage-proof material made from high molecular polymers. It can prevent liquid leakage and gas evaporation, and is widely used in construction, transportation, subway, tunnel and engineering projects.

[0003] In the process of developing this utility model, the inventors discovered the following problems with the existing technology: 1. When installing existing waterproof membranes, it is usually necessary to use various auxiliary tools and bolts to install and fix the waterproof membrane, which greatly reduces the convenience of installation. Moreover, the bolts are prone to stripping after long-term use and are also prone to corrosion, which affects the installation strength of the waterproof membrane and thus reduces the waterproof effect; 2. When existing waterproof membranes are spliced ​​and installed, each waterproof membrane is installed separately, resulting in gaps at the joints between the waterproof membranes. When external floods impact the membranes, the flood may leak from the gaps between the waterproof membranes, thus failing to meet people's usage needs. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a splicing waterproof board, including a shell assembly 1 and a connecting block 2. A slot 3 is provided on one side of the connecting block 2, and a cavity 4 is provided inside the connecting block 2. A connecting shaft 5 is provided at both ends of the cavity 4 through bearings. Several cams 6 are provided on the outside of the connecting shaft 5. Slide grooves 7 are provided on the two inner walls of the cavity 4. A slider 8 is provided inside the two slide grooves 7. A moving plate 9 is provided between the two sliders 8. Several positioning rods 10 are provided on one side of the moving plate 9. Springs 11 are provided on the outside of the several positioning rods 10. A slot 12 is provided on one side of the top of the connecting block 2. A support plate 13 is provided on the top of the outside of the connecting shaft 5. A knob 14 is provided on the top of the support plate 13.

[0021] In this embodiment, as Figure 1 As shown, the outer casing assembly 1 includes a waterproof membrane body 101, a waterproof baffle 102 is provided on one side of the waterproof membrane body 101, and an insert block 103 is provided on the side of the waterproof membrane body 101 away from the waterproof baffle 102. A plurality of positioning grooves 104 are provided on one side of the insert block 103.

[0022] In this embodiment, as Figure 1 As shown, the positioning groove 104 and the positioning rod 10 are designed with a snap-fit ​​structure; this enables the waterproof membrane to be quickly spliced ​​and installed, greatly improving the convenience of splicing and installing the waterproof membrane, solving the problem that the bolts will rust and affect the installation strength of the waterproof membrane due to long-term use of bolt installation, thereby greatly increasing the waterproof effect of the waterproof membrane.

[0023] In this embodiment, as Figure 1 As shown, the internal dimensions of slot 3 are consistent with the external dimensions of insert block 103; this effectively prevents external floodwater from flowing into underground locations through the connection gaps between the waterproofing membranes, significantly improving the flood protection effect of the waterproofing membranes and avoiding the problem of floodwater leakage from the connection gaps between the waterproofing membranes, thus meeting the requirements for waterproofing membranes used for flood control.

[0024] In this embodiment, as Figure 3 As shown, the slider 8 and the groove 7 are connected by a sliding connection; this increases the stability of the moving plate 9 during movement, thereby preventing the moving plate 9 from shifting or tilting during movement.

[0025] In this embodiment, as Figure 2 As shown, several wear-resistant pads are embedded in the side of the movable plate 9 away from the positioning rod 10; this prevents the cam 6 from rubbing against the movable plate 9 for a long time, thus increasing the service life of the movable plate 9.

[0026] In this embodiment, as Figure 3 As shown, a snap-fit ​​structure is provided between the knob 14 and the slot 12; this fixes the connecting shaft 5 after the rotation angle, preventing the positioning rod 10 from disengaging from the positioning slot 104 due to the rotation of the connecting shaft 5 during use, thereby increasing the fixing effect between the connecting block 2 and the insert block 103.

[0027] The method of use and advantages of this utility model: When using this type of spliced ​​waterproof board, the working process is as follows:

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, firstly, the insert 103 on one side of the waterproof membrane body 101 is inserted into the slot 3 on one side of the connecting block 2. The cooperation of the insert 103, slot 3, and waterproof baffle 102 effectively prevents external floodwater from flowing into the underground site through the gaps between the waterproof membranes, significantly improving the floodproof effect of the waterproof membrane and avoiding the problem of flood leakage from the gaps between the waterproof membranes. Then, the handle is rotated, causing the connecting shaft 5 to rotate. The connecting shaft 5 drives several cams 6 to rotate. When the highest point of several cams 6 contacts one side of the moving plate 9, the moving plate 9 moves towards one side of the cavity 4 under the cooperation of the slider 8 and the slide groove 7. At this time, the moving plate 9 drives the four positioning rods 10 to move, and simultaneously, the moving plate 9 synchronously compresses the four springs 11 until the four positioning rods 10 are engaged with one side of the insert 103. The four positioning slots 104 are connected to the positioning rod 10, forming a snap-fit ​​structure. This enables rapid splicing and installation of the waterproof membrane, greatly improving the convenience of splicing and installation. It solves the problem of bolt corrosion affecting the installation strength of the waterproof membrane due to long-term use of bolt installation, thus significantly increasing the waterproof effect of the waterproof membrane. After the waterproof membrane is installed and fixed, the knob 14 is rotated, so that the knob 14 is snapped into the slot 12 under the thread engagement of the support plate 13, and a snap-fit ​​structure is formed between the slot 12 and the knob 14. This fixes the connecting shaft 5 after rotation, preventing the positioning rod 10 from disengaging from the positioning slot 104 due to the rotation of the connecting shaft 5 during use. This increases the fixing effect between the connecting block 2 and the insert block 103, thus meeting the requirements of the waterproof membrane for flood control.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
