Moreover, the durability is poor, the adhesive sealing and anti-seepage effect is not good and it is prone to aging, and the weld joint is prone to corrosion failure. Utility Model Content

[0016] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please refer to Figures 1-4 A sawtooth anchored copper waterstop and rubber waterstop connection structure is characterized by comprising: a copper waterstop mounting plate 1, a rubber waterstop plate 3 installed on one side of the copper waterstop mounting plate 1, which is used to cooperate with the copper waterstop mounting plate 1 to achieve the waterstop function, and a stainless steel stabilizing plate 5 installed between the copper waterstop mounting plate 1 and the rubber waterstop plate 3 for overall connection.

[0018] Please refer to Figures 1-3 The auxiliary components are located on both sides of the copper waterstop mounting plate 1 and are used to fix the copper waterstop mounting plate 1 and the rubber waterstop plate 3. The auxiliary components include continuous sawtooth grooves 2 opened at both ends of the copper waterstop mounting plate 1 and grooves opened inside the rubber waterstop plate 3. One side of the copper waterstop mounting plate 1 and the two continuous sawtooth grooves 2 are inserted into the inside of the groove. A limiting component is also installed at the bottom of the copper waterstop mounting plate 1 for limiting the position of the copper waterstop mounting plate 1. First, the two ends of the copper waterstop mounting plate 1 are cut into continuous sawtooth grooves 2 using a tool. Then, the surface of the copper waterstop mounting plate 1 is galvanized for rust prevention. At the same time, grooves matching the copper waterstop mounting plate 1 and the continuous sawtooth grooves 2 are made inside the rubber waterstop plate 3 using a grooving tool, and the inside of the grooves is roughened. After roughening, urethane sealant is filled into the inside of the grooves. During installation, the continuous sawtooth grooves 2 are aligned with the grooves and pressed in until they are completely fitted, forming a mechanical interlocking flexible connection. At the same time, polyurethane sealant is applied to the interface between the copper waterstop mounting plate 1 and the rubber waterstop plate 3 and cured. Two stainless steel stabilizing plates 5 are placed at the top and bottom ends of the rubber waterstop plate 3, respectively. Then, holes are drilled on the surface. Finally, stainless steel fixing bolts 4 and fixing nuts 7 are used for locking. Polyurethane sealant is brushed onto the surface. The copper waterstop mounting plate 1 and the rubber waterstop plate 3 are effectively anchored through flexible mechanical interlocking. Through the polyurethane sealant in the groove and the external locking device, the overlapping part is effectively sealed, improving the anti-seepage overlapping effect.

[0019] Furthermore, such as Figure 5 As shown, the limiting component includes a limiting protrusion 6 fixedly connected to the bottom of the copper waterstop mounting plate 1 and a limiting groove installed on one side of the rubber waterstop plate 3. An adhesive layer 8 is fixed to the bottom of the limiting protrusion 6. Both the limiting protrusion 6 and the adhesive layer 8 are inside the limiting groove. A fixing component is provided between the copper waterstop mounting plate 1 and the stainless steel stabilizing plate 5 to fix the stainless steel stabilizing plate 5 and the copper waterstop mounting plate 1. Based on this, by placing the limiting protrusion 6 and the rubber waterstop plate 3 inside the limiting groove, the copper waterstop mounting plate 1 and the rubber waterstop plate 3 can be properly limited during installation, avoiding shaking and displacement of the copper waterstop mounting plate 1 and the rubber waterstop plate 3 during installation, thereby improving the waterproof effect of the copper waterstop mounting plate 1 and the rubber waterstop plate 3.

[0020] Furthermore, such as Figures 1-5As shown, the fixing assembly includes multiple stainless steel fixing bolts 4 mounted on the stainless steel stabilizing plate 5 and multiple mounting holes formed on the copper waterstop mounting plate 1, the rubber waterstop plate 3, and the stainless steel stabilizing plate 5. Each of the multiple stainless steel fixing bolts 4 passes through the mounting holes. Each of the multiple stainless steel fixing bolts 4 is equipped with a stabilizing component for stabilizing the stainless steel stabilizing plate 5 and the copper waterstop mounting plate 1. The stabilizing component includes fixing nuts 7 mounted on the multiple stainless steel fixing bolts 4, with the fixing nuts 7 located on the top of one of the stainless steel stabilizing plates 5. Therefore, when it is necessary to connect the copper waterstop mounting plate 1, the rubber waterstop plate 3, and the stainless steel stabilizing plate 5, firstly, one end of each of the multiple stainless steel fixing bolts 4 passes through the multiple mounting holes and extends to the outside of one of the stabilizing plates 5. Then, the multiple fixing nuts 7 are aligned with the multiple stainless steel fixing bolts 4. Subsequently, the fixing nuts 7 are rotated so that one side of the fixing nuts 7 rotates to a suitable position and fits tightly against the stainless steel stabilizing plate 5, thereby achieving the connection and installation between the copper waterstop mounting plate 1, the rubber waterstop plate 3, and the stainless steel stabilizing plate 5.

[0021] Furthermore, such as Figures 1-3 As shown, the rubber waterstop 3 has grooves, the groove depth is slightly greater than the tooth height, and the groove width is equal to the tooth base width. The serrations are pressed into the grooves to form a mechanical anchor. The continuous serrated groove 2 is an isosceles triangle with a tooth height of 5-8mm, a tooth pitch of 10-15mm, and a tooth tip angle of 60°-75°. The serrations are distributed in both directions to ensure that multiple teeth are simultaneously stressed during pull-out. The serration-groove interlocking provides pull-out resistance to meet the lap joint requirements. Based on this, the bidirectional distribution of the continuous serrated groove 2 ensures that the copper waterstop mounting plate 1 and the rubber waterstop 3 are simultaneously stressed during pull-out, thereby improving the overall stability of the copper waterstop mounting plate 1 and the rubber waterstop 3 and preventing them from shaking and falling off, which would affect the waterproofing effect of the copper waterstop mounting plate 1 and the rubber waterstop 3.

[0022] Furthermore, such as Figures 1-3 As shown, the groove length covers the overlap section of the copper waterstop mounting plate 1 by ≥150mm. The inside of the groove is filled with urethane sealant, and the urethane sealant is tightly bonded to the copper waterstop mounting plate 1. The connecting end surface of the rubber waterstop plate 3 is coated with 2mm thick polyurethane sealant, which forms a double waterproof barrier after compression. Based on this, by applying thick polyurethane sealant to the connecting end surface of the rubber waterstop plate 3, the copper waterstop mounting plate 1 and the rubber waterstop plate 3 can be effectively waterproofed and sealed, thereby improving the waterproof effect of the copper waterstop mounting plate 1 and the rubber waterstop plate 3.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
