[0029] Example 1

[0030] Combined with Figure 1-7 The combinable waterstop strip of this embodiment includes a first waterstop component 1 and a second waterstop component 2. The first waterstop component 1 includes a first waterstop member 11 and a clamping member 12. The clamping member 12 has an open end 121 and a closed end 122. The closed end 122 is connected to the first waterstop member 11. A cavity 123 is formed between the open end 121 and the closed end 122. The second waterstop component 2 includes a second waterstop member 21 and a clamping protrusion 22 connected to the second waterstop member 21. The clamping protrusion 22 is movably and rotatably matched with the cavity 123. The clamping protrusion 22 is an expansion strip or a grouting pipe. During the first phase of construction, the first water stop 11 is first installed in the embedded structural member (such as a steel cage), and then the first phase of concrete pouring is carried out. During the second phase of construction, the latching protrusion 22 of the second water stop 21 enters the cavity 123 through the open end 121 and cooperates with the cavity 123 of the clamping member 12, and then the second phase of concrete pouring is carried out. By first disassembling the first water stop 11 and the second water stop 21 for the first phase of construction, and then combining the first water stop 11 and the second water stop 21 for the second phase of construction, the defects of the conventional integrated waterproof belt are effectively avoided. In addition, the detachable combination structure of the first water stop and the second water stop is also suitable for the situation where the construction joint space in special parts (such as the construction joint close to the foundation pit retaining structure) is narrow, which broadens the application range of the water stop structure and improves the reliability of joint water stopping.

[0031] Example 2

[0032] Combined with Figure 1 and 4 Compared with the technical solution of Example 1, the modular water stop strip of this embodiment can be improved as follows: the end of the first water stop 11 away from the clamping member 12 is provided with a first limiting member 13, and the first limiting member 13 is connected to the first fixing plate 4; the end of the second water stop 21 away from the clamping protrusion 22 is provided with a second limiting member 23, and the second limiting member 23 is connected to the second fixing plate 5; the first water stop 11 and the second water stop 21 are both made of rubber, and the first fixing plate 4 and the second fixing plate 5 are both made of steel. The first limiting member 13 and the second limiting member 23 play a good limiting role, preventing the first water stop 11 and the second water stop 21 from displacement, and the first fixing plate 4 and the second fixing plate 5 respectively increase the stability of the connection between the first water stop 11 and the second water stop 21 and the concrete structure.

[0033] Example 3

[0034] Combined with Figure 1 and 4Compared with the technical solutions of Embodiment 1 or 2, the modular water stop of this embodiment can be improved as follows: the diameter of the first limiting member 13 gradually decreases from the end close to the clamping member 12 to the end close to the first fixing plate 4, and the diameter of the second limiting member 23 gradually decreases from the end close to the clamping protrusion 22 to the end close to the second fixing plate 5. Both the first limiting member 13 and the second limiting member 23 are conical or hammer-shaped structures, the end with a larger diameter is convenient for limiting, and the end with a smaller diameter is convenient for connecting with the first fixing plate 4 or the second fixing plate 5.

[0036] Combined with Figure 1 and 4 Compared with any one of the technical solutions in Examples 1-3, the modular water stop of this embodiment can be improved as follows: the first stopper 13 is provided with a first slot, the length of the first fixing plate 4 entering the first slot is greater than half of the length of the first stopper 13, the second stopper 23 is provided with a second slot, the length of the second fixing plate entering the second slot is greater than half of the length of the second stopper 23. This is conducive to the first fixing plate 4 being firmly connected to the first stopper 13, and the second fixing plate 5 being firmly connected to the second stopper 23.

[0037] Example 5

The bending setting of the first bending portion 14 and the second bending portion 24 is not only conducive to the compactness of the concrete pouring directly below the water stop, but also increases the stability of the first water stop 11 and the concrete poured in the early construction stage, and increases the stability of the second water stop 21 and the concrete poured in the later construction stage.

[0039] Example 6

[0040] Combined with Figure 4, compared with any one of the technical solutions of embodiments 1-5, the modular water stop of this embodiment can be improved as follows: the lower end surface of the opening end 121 is coaxially arranged with the first water stop 11, and the opening angle of the opening end 121 is 30-40°. When the water stop is used for the side wall, the second water stop 21 abuts against the lower end surface of the opening end 121, and the first water stop 11 and the second water stop 21 are in a straight line shape. When the water stop is used for the top plate or the bottom plate, the second water stop 21 abuts against the upper end surface of the opening end 121, and the first water stop 11 and the second water stop 21 are in a V shape, that is, the rotation angle of the second water stop 21 in the cavity 123 is 30-40°, and the rotation angle can be 30°, 35°, and 40°, which is convenient for flexibly adjusting the setting angle between the second water stop 21 and the first water stop 11 according to actual conditions, which is beneficial to the compactness of the concrete pouring directly below the water stop, and further improves the water stopping effect of the water stop structure. The opening angle of the open end 121 is α.

[0041] Example 7

[0042] Combined with Figure 5 and 6 Compared with any one of the technical solutions of embodiments 1-6, the modular water stop strip of this embodiment can be improved as follows: the center line of the opening end 121, the first water stop member 11, and the second water stop member 21 are coaxially arranged, and the opening angle of the opening end 121 is 80-100°. The opening angle of the opening end 121 is large, which facilitates the first water stop member 11 made of rigid material to enter the cavity 123, and the opening angle can be 80°, 90°, or 100°.

[0043] Example 8

[0044] Combined with Figure 1-3 , compared with any one of the technical solutions of Examples 1-7, the combinable water stop strip of this embodiment can be improved as follows: it also includes an air bag 3, the air bag 3 has an inflated state and a deflated state, when the air bag 3 is in the inflated state, the air bag 3 is located inside the cavity 123, and the clamping protrusion 22 is separated from the cavity 123; when the air bag 3 is in the deflated state, the air bag 3 is separated from the cavity 123, and the clamping protrusion 22 is rotationally matched with the cavity 123. During the first phase of construction, it is necessary to pre-embed the first water stop 11 in the building, place the air bag 3 in the clamping part 12, and pour concrete after inflating the air bag 3. The inflated air bag 3 is located in the cavity 123 of the clamping part 12 to prevent the clamping part 12 from being squeezed and deformed when the concrete is poured during the first phase of construction. During the second phase of construction, it is only necessary to deflate and remove the protective air bag 3, match the clamping protrusion 22 of the second water stop 21 with the cavity 123 of the clamping part 12, and then pour concrete. The shape of the airbag 3 matches the shape of the cavity 123 , so that the clamping member 12 forms a solid cylinder, a cube or other shapes.

[0045] Example 9

[0046] Combined with Figure 6 , the modular water stop of this embodiment can be improved as follows compared with any of the technical solutions of embodiments 1-8: the first water stop 11 is provided with a first groove 15 and a first slot 16 along the length direction, the first groove 15 is connected to the first slot 16, the second water stop 21 is provided with a second groove 25 and a second slot 26 along the length direction, the second groove 25 is connected to the second slot 26, the first groove 15 and the second groove 25 are both used for steel bars to pass through, and the first slot 16 and the second slot 26 are both used for binding steel bars. When the water stop conflicts with the longitudinal and transverse steel bars of the structure at a special construction joint, the steel bars can pass through the first groove 15 or the second groove 25 and be bound in the first slot 16 or the second slot 26, so as to facilitate the smooth installation of the first water stop and the second water stop. In other embodiments, the first water stop 11 may not need to be provided with the first groove 15, and the second water stop 21 may not need to be provided with the second groove 25.

[0047] The above schematically describes the present invention and its implementation methods, which are not restrictive.
