Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a sealing water-stopping mechanism for preventing leakage of a water-stopping joint. Background Art

[0002] In construction engineering, a water stop is a device used to connect pipes on the upper and lower floors of a building. When installing, it is no longer necessary to reserve holes during the construction process. It is a device that is cast and formed at one time with the cast-in-place slab during construction.

[0003] When existing building water-stop joints are in use, in order to improve the sealing effect of the combination between the main body and the concrete structure, an uneven structure is set on the outside of the water-stop joint. However, due to the difference in material structure between concrete and the water-stop joint after construction, cracks may still appear at the joint between concrete and the water-stop joint after concrete shrinkage and other phenomena occur. In addition, the existing water-stop joints are mainly fixed to the bottom wooden formwork through screws and other structures during arrangement. When the bottom wooden formwork is removed after the construction of the floor concrete structure is completed, it is necessary to separate the formwork from the screws with force. At this time, the water-stop joint is subjected to a large tensile force, which is likely to further affect the sealing effect of the water-stop joint and the concrete structure, making it inconvenient to use.

The inner circumference surface of the fixing ring 6 away from the inner thread is set as a conical structure, which is convenient for the fixing ring 6 to press and connect the elastic rubber sleeve 5 with the clamping ring of the connecting ring 3;

[0042] A lifting assembly is provided to perform concave deformation treatment on the elastic rubber sleeve 5, the lifting assembly is vertically plugged into the combination ring 2 above the water stop joint main pipe 1, the lifting assembly includes a synchronous ring 13 and a plurality of plugging pull rods 11, the lower ends of the plurality of plugging pull rods 11 respectively penetrate the combination ring 2 above the water stop joint main pipe 1 and are provided with a first pull rope 14, and one side of the first pull rope 14 is connected to one side of the elastic rubber sleeve 5, the water stop joint main pipe 1 is located above the combination ring 2 and a plurality of guide blocks 9 are horizontally symmetrically provided above the combination ring 2, a plurality of combing tubes 8 are provided in a vertical annular array in the combination ring 2 above the water stop joint main pipe 1, and the synchronous ring 13 is horizontally sleeved with the water stop At the upper end of the section main tube 1, a plurality of plugging rods 11 are vertically symmetrically arranged below the synchronization ring 13, a guide groove is opened through the center of the guide block 9, and the lower ends of the plurality of plugging rods 11 are respectively movably passed through the plurality of guide blocks 9 and movably inserted into the plurality of combing tubes 8, and elastic blocks 12 are horizontally arranged on one side of the guide groove of the guide block 9, and a plurality of annular grooves are opened on the plugging rods 11, and one side of the elastic block 12 is inserted into one of the annular grooves of the plugging rods 11, and an annular sealing ring can be arranged on the side of the plugging rod 11 inserted into the combing tube 8 to avoid pressurization failure of the chamber composed of the combination ring 2 and the elastic rubber sleeve 5 in the later stage;

[0043] The elastic rubber sleeve 5 is located between the two combination rings 2 and has a plurality of pull plates 15 symmetrically arranged horizontally on one side thereof. A plurality of first pull ropes 14 are respectively arranged at the lower end of the sealing pull rod 11 inserted into the combing tube 8. A plurality of first pull ropes 14 pass through one side of the combing tube 8 and are respectively bent and connected with the plurality of pull plates 15 on the inner circumference of the elastic rubber sleeve 5. The height of the lower end of the combing tube 8 is slightly higher than the center line of the elastic rubber sleeve 5 where the pull plate 15 is arranged. When the first pull rope 14 pulls the pull plate 15, it is pulled horizontally. In addition, a grouting joint 35 is connected to one side of the upper end of the combination ring 2 above the water stop joint main pipe 1. The grouting joint 35 is plugged with a disposable one-way valve or a one-way valve that is threaded and reusable.

[0044] In this embodiment: through the elastic characteristics of the elastic rubber sleeve 5, the elastic rubber sleeve 5 is first put on the two combined rings 2, and then the two sides of the elastic rubber sleeve 5 are respectively inserted into the built-in groove 4 of the connecting ring 3. At this time, the fixing ring 6 is connected to the connecting ring 3 through the internal and external threads, and the fixing ring 6 cooperates with the clamping ring to clamp and fix the elastic rubber sleeve 5. At this time, the blocking rod 11 and the first pull rope 14 are pulled up by the synchronous ring 13, so that the elastic block 12 is engaged with the annular groove of the blocking rod 11, and the center of the elastic rubber sleeve 5 is kept concave toward the side of the water stop joint main pipe 1, so as to increase the contact area between the cast-in-place floor slab and the device. When the cast-in-place floor slab is vibrated and solidified When it has been solidified for more than 6 hours and has not completely solidified, cement slurry is injected into the chamber surrounded by the two combined rings 2 and the elastic rubber sleeve 5 under high pressure through the grouting joint 35. At this time, the cement slurry fills the combined ring 2 and the elastic rubber sleeve 5. The elastic rubber sleeve 5 is compressed and combined with the external concrete structure under the action of the internal high pressure. At the same time, under the action of the overflow groove 7 set in the fixed ring 6, a small amount of cement slurry flows out of the elastic rubber sleeve 5 through the built-in groove 4 position of the connecting ring 3 and the overflow groove 7 position. At this time, the slight gap between the elastic rubber sleeve 5 and the external cast-in-place floor slab concrete can be strengthened and compensated by the pressurized cement slurry to improve the sealing and water-stopping effect.

[0045] Embodiment 2: On the basis of embodiment 1, a matching component is provided to facilitate fixing the water stop joint main pipe 1 to the bottom wooden formwork of the cast-in-place floor slab. The matching component is horizontally arranged in the fixed foot 17 by releasing the component. The matching component includes two matching lap plates 21. A fixing screw 25 is inserted and inserted vertically through the center of the fixed foot 17, and the fixing screw 25 is located between the two matching lap plates 21. The fixed foot 17 is provided with an operating cavity 18. A cushion block 19 is horizontally arranged at the lower end of the center of the operating cavity 18. Two support shafts 20 are symmetrically arranged on one side of the upper end of the cushion block 19. The two support shafts 20 are both rotatably provided with matching lap plates 2 1. An operation opening is provided on one side of the upper end of the fixed foot 17. A removal groove 24 is provided through the pad 19 located just below the operation opening. Two matching lap plates 21 are provided with lap grooves 22 located above one side of the operation opening. A clearance groove 23 is provided through the lower ends of the two lap grooves 22. A fixing screw 25 is vertically inserted in the removal groove 24. The screw head of the fixing screw 25 is inserted into the two lap grooves 22 of the two matching lap plates 21. There is a certain distance between the two matching lap plates 21. When the two matching lap plates 21 are in a parallel state, the virtual axes of the two lap grooves 22 are coaxial with the clearance groove 23 and the operation opening.

[0046] The screw head diameter of the fixing screw 25 is larger than the combined diameter of the two easing grooves 23, and a sealing cap 34 is inserted into the operating port of the fixing foot 17. When the fixing screw 25 passes through the operating port and penetrates the easing groove 23 to connect with the wooden template, the screw head of the fixing screw 25 is inserted into the lap grooves 22 of the two matching lap plates 21. At this time, the water stop joint main pipe 1 cannot move left and right and up and down. There is a certain gap between the screw head of the fixing screw 25 and the lower end of the lap groove 22 of the matching lap plate 21 to avoid friction and prevention of movement caused by the later movement of the matching lap plate 21, thereby ensuring that after the fixing screw 25 is inserted into the fixing foot 17, the water stop joint main pipe 1 will not shake significantly up and down.

[0047] Embodiment 3: On the basis of embodiment 2, a release assembly is provided for controlling the release of the connection between the water stop joint main pipe 1 and the fixing screw 25, and the release assembly includes a push plate 26, a pull plate 27 and a second pull rope 32. One side of the push plate 26 is movably connected to two matching lap plates 21, and the second pull rope 32 is connected to the first pull rope 14 on one side. Two sides of the cushion block 19 are horizontally movably connected with two synchronous guide rods 28. The two synchronous guide rods 28 penetrate the two sides of the cushion block 19 and are respectively provided with a push plate 26 and a pull plate 27. Two push grooves 29 are provided on both sides of the push plate 26, and two matching lap plates are provided. The outer side of 21 is horizontally provided with a connecting ear 30, and a release rod 31 is horizontally connected between the push groove 29 and the connecting ear 30 on the same side through a pin shaft. The lower end of the combined ring 2 located below the water stop joint main pipe 1 is provided with an annular clamping plate 16, and a spacing layer is provided between the annular clamping plate 16 and the water stop joint main pipe 1. The operating chamber 18 is connected with the spacing layer. The lower end of the second pull rope 32 passes through the combined ring 2 below the water stop joint main pipe 1 and is movably inserted into the spacing layer. A reversing rod 33 is horizontally provided on one side of the spacing layer in the operating chamber 18, and the second pull rope 32 is connected to one side of the pulling plate 27 after overlapping the reversing rod 33;

[0048] The degree of the center depression of 5a can be controlled by pulling through the up and down movement of 13a. After the external concrete of the water stop joint main pipe 1 is poured, the synchronous ring 13 is further pulled to control the lifting of the first pull rope 14 and the second pull rope 32. At this time, the center of the elastic rubber sleeve 5 is further sunken inward, and the second pull rope 32 pulls the pulling plate 27 to move. At this time, the pulling plate 27 pulls the push plate 26 to move synchronously through the synchronous guide rod 28. When the push plate 26 moves to the position of the matching lap plate 21, a release device is arranged horizontally between the push plate 26 and the matching lap plate 21. Rod 31, at this time, releasing rod 31 will push the matching lap plate 21 to rotate along the supporting shaft rod 20, the two matching lap plates 21 are opened to both sides, and the fixing screws 25 are separated from the enclosure of the two matching lap plates 21. The fixing screws 25 cannot be lifted under the downward pressure of the upper concrete at this time, and cannot move left and right under the limiting effect of the fixing screws 25. When it is necessary to remove the wooden formwork under the water stop joint main pipe 1, the fixing screws 25 can be directly connected and removed without forceful disassembly, which affects the connection and sealing effect between the water stop joint main pipe 1 and the cast-in-place floor slab;

[0049] The diameter of the removal slot 24 is larger than the head diameter of the fixing screw 25 , and the first pull rope 14 and the second pull rope 32 can be thin steel wire ropes.
