[0031] Grouting assembly is arranged at the top of adaptive assembly, sealing assembly is arranged at both ends of adaptive assembly, and supporting piece 13 is arranged at the bottom of adaptive assembly.

[0032] The support 13 comprises an adjusting assembly arranged at the bottom of the adapting assembly and a pressing member arranged outside the adjusting assembly.

[0033] The components arranged in the docking assembly 1 can realize stable and firm docking, and meanwhile, the stability of the water stop steel plate body 2 during use is enhanced.

[0034] Preferably;

[0035] As shown in Figure 3 The adapting assembly comprises a connecting plate 11 and a docking groove 111, the connecting plate 11 is arranged outside the water stop steel plate body 2, and the outer end of the connecting plate 11 is provided with the docking groove 111, so as to facilitate the insertion of the water stop steel plate body 2 to realize mutual adaptation.

[0036] Further;

[0037] As shown in Figure 4 The pouring assembly comprises a communication hole 14 and a grouting hole 15, the top of the connecting plate 11 is provided with the communication hole 14 and the grouting hole 15, the communication hole 14 and the grouting hole 15 are communicated, and the pouring operation is facilitated to facilitate the flow into the inner cavity of the connecting plate 11.

[0038] Still further;

[0039] As shown in Figure 2 and 3 The sealing assembly comprises an anti-skid line 16 and a sealing strip 17, the inner side wall of the connecting plate 11 is provided with the sealing strip 17, and the inner side wall of the connecting plate 11 is also provided with the anti-skid line 16, so as to facilitate the anti-skid and the sealing property when the water stop steel plate body 2 is inserted.

[0040] Among them

[0041] As shown in Figure 4 The locking member 12 comprises a locking bolt and a threaded hole, the outer side of the connecting plate 11 is provided with the threaded hole, and the inside of the threaded hole is threadedly connected with the locking bolt, so as to realize the function of bolted fixation, so as to ensure that the water stop steel plate body 2 is stably fixed at the preset position.

[0042] In addition;

[0043] As shown in Figure 3 The support 13 comprises an adjusting screw 132 and a nut 133, the adjusting screw 132 is fixedly installed at the bottom of the connecting plate 11, and the nut 133 is threadedly connected outside the adjusting screw 132, so as to realize the support of the above-mentioned components, and also realize the function of stable locking fixation.

[0044] Finally;

[0045] As shown in the figure, the clamping component includes a clamping piece 131 and anti-slip teeth. The clamping piece 131 is sleeved on the outside of the adjusting screw 132, and the inner side of the clamping piece 131 is engraved with anti-slip teeth, which can increase the clamping effect when fixed.

[0046] Based on the above;

[0047] When in use, insert the waterstop steel plate body 2 into the docking groove 111, fix the waterstop steel plate body 2 in the docking groove 111 by rotating the locking bolt, and then adjust the nut 133 on the support 13 to make the clamp 131 tightly clamp the steel frame, thereby fixing the docking assembly 1.

[0048] Grouting or adhesive is injected into the connecting component 1, i.e., the connecting plate 11, through the grouting hole 15. The grout will flow into the grouting cavity between the two connecting grooves 111 through the connecting hole 14, thereby ensuring the sealing between the water-stop steel plate body 2 and the connecting groove 111, and further improving the waterproof performance of the joint.

[0049] like Figure 1 As shown, the clip 131 is clamped and fixed on the preset reinforcing bar, and the bottom of the preset reinforcing bar is provided with a base plate for supporting and fixing several groups of reinforcing bars.

[0050] The groove wall of the mating groove 111 away from the sealing strip 17 is provided with anti-slip texture 16. These anti-slip textures 16 can increase the friction between the waterstop steel plate body 2 and the mating groove 111, allowing the waterstop steel plate body 2 to slide within the mating groove 111, thereby improving the stability of the structure. At the same time, the inner side of the clamp 131 is also provided with anti-slip texture 16 to increase the friction with the steel reinforcement frame and ensure a stable connection between the support member 13 and the steel reinforcement frame.

[0051] The above embodiments are mainly for locations containing right-angle corners. Example 2

[0052] like Figure 5 As shown in the figure, in this embodiment, the connection angle of the two connecting plates 11 can be designed according to the connection position of the two waterstop steel plates. When connecting two waterstop steel plates in the same direction, the connection angle of the two connecting plates 11 is 180°.

[0053] The implementation principle of a waterproofing structure at the joint between old and new concrete in this application embodiment is as follows:

[0054] When in use, insert the water-stop steel plate into the docking groove 111, and fix the water-stop steel plate in the docking groove 111 by rotating the locking bolt. Then, adjust the nut 133 on the support 13 to make the clamp 131 tightly clamp the steel frame. Grout is injected into the docking groove 111, and the grout will fill the grouting cavity, further enhancing the sealing between the water-stop steel plate and the docking assembly 1.

[0055] In the above two embodiments, the grouting structure can be omitted, that is, the grouting hole 15 and the communication hole 14 are not arranged on the butt joint assembly 1, and the rubber sealing strip 17 does not need to be arranged in the butt joint groove 111, and the simplified structure is suitable for some occasions with low requirements on waterproof performance, and the production cost and construction difficulty can be reduced.

[0056] The above are preferred embodiments of the application, and do not limit the protection scope of the application, so: any equivalent changes made on the structure, shape, principle of the application should be covered within the protection scope of the application.
