Description

Technical Field

[0001] The utility model discloses a concrete outer wall screw hole anti-leakage plugging structure, belonging to the technical field of wall reserved hole plugging construction. Background Art

[0002] A large number of through-the-wall screws are used in the construction of the exterior walls of shear walls and frame-shear structures. The sealing of through-the-wall screw holes involves the risk of leakage in the exterior walls and must be taken seriously during construction. In the case of exterior wall leakage, a large part is caused by the loose sealing of the screw holes. The traditional methods of sealing the screw holes in the exterior walls are: flushing out the PVC pipe and cleaning it; first filling the interior walls with cement sand; filling the expansion cement mortar from the outside to the inside, inserting steel bars, smoothing the surface, and then applying cement-based waterproof coating. This method is not easy to operate, the depth of cement mortar insertion cannot be controlled, and the sealing does not meet the requirements.

[0003] Chinese patent number: CN215563434U, mentions a device for plugging screw holes in external walls, which is provided with screw holes and connecting rods, the outer end of the screw holes is provided with installation slots, and the connecting rods are provided with a dense component for sealing the screw holes, and a pressure piece installed on the head and adapted to the installation slots. By providing a dense component and a pressure piece located at the head on the connecting rod, external force is applied to the pressure piece to gradually push it toward the inside of the screw hole, which can effectively ensure the dense anti-leakage effect of the device, but the device has a simple structure, is not well adapted to screw holes of different sizes, and requires multiple use of disposable materials, which is relatively wasteful.

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1-Figure 5 The utility model provides a technical solution: a concrete external wall screw hole anti-leakage plugging structure, including a first installation shell 1, a second installation shell 2 and a square block 17, the first installation shell 1 is fixedly connected with a screw 3 at the right end, the annular side of the screw 3 is screwed with an internal thread column 4, the annular side of the internal thread column 4 is fixedly connected with a sealing gasket 5, the second installation shell 2 is respectively penetrated and slidably installed with a moving column 15 on the upper, lower, left and right sides, and the outer ends of the plurality of moving columns 15 are respectively installed with a resistance block 14, and the outer sides of the plurality of resistance blocks 14 are commonly sleeved with a toughness sealing ring 8, and the inner ends of the plurality of moving columns 15 are respectively installed with a spring 18, and the upper and lower sides of the square block 17 are respectively installed with a spring 18. The four sides are respectively installed with inclined slide grooves 16, and movable plates 19 are respectively installed in the slide grooves of the multiple inclined slide grooves 16. Multiple springs 18 are respectively connected to the multiple movable plates 19. A square shell 11 is installed on the left end of the second mounting shell 2, and an inner sealing ring 9 is sleeved on the right end of the square shell 11. An external threaded tube 10 is sleeved on the outer periphery of the square shell 11. The annular side of the external threaded tube 10 is screwed with an internal threaded tube 6, and the right end of the internal threaded tube 6 is fixedly connected with an external sealing ring 7. This design solves the problems that the original device has a simple structure, cannot be well adapted to screw holes of different sizes, and needs to use disposable materials many times, which is relatively wasteful.

[0020] The left end of the square block 17 is provided with a handle 12, and the left end of the handle 12 is slidably provided with a block 13, which facilitates pushing and pulling the square block 17, and facilitates cooperating with a plurality of blocking plates 20 to limit the handle 12. A plurality of blocking plates 20 are installed on the inner wall below the square shell 11.

[0021] The block 13 can move up and down relative to the handle 12. When moving up, the block 13 can smoothly pass through the blocking plate 20. When moving down, the block 13 is embedded between the two blocking plates 20 to be locked.

[0022] The front and rear sides of the handle 12 are respectively slidably connected to the inner wall of the square shell 11. By slidably connecting the front and rear sides of the handle 12 to the inner wall of the square shell 11, the handle 12 is pulled more stably. The left end of the first mounting shell 1 is butted with the right end of the second mounting shell 2. By butting the left end of the first mounting shell 1 with the right end of the second mounting shell 2, it is convenient to insert the screw hole, and the other end of the hole is sealed by the sealing gasket 5. The block 13 is made of iron material, and magnetic plates are respectively embedded in the plurality of blocking plates 20. By making the block 13 of iron material, it is convenient to cooperate with the magnetic plates embedded in the plurality of blocking plates 20, so that the connection between the block 13 and the plurality of blocking plates 20 is more stable.

[0023] The working principle of the utility model is as follows: when in use, first unscrew the internal thread column 4 at the right end of the device, and then insert the right end of the device into the screw hole. If the screw hole penetrates the wall, then the screw 3 will extend from the other end of the screw hole, and then the internal thread column 4 is screwed with the screw 3, so that the internal thread column 4 is reset, and then the sealing gasket 5 is tightly attached to the wall;

[0024] If the screw hole does not penetrate the wall, there is no need to reset the internal threaded column 4, then unscrew the internal threaded tube 6, push the handle 12, so that the multiple inclined slide grooves 16 and the multiple movable plates 19 slide relative to each other, the positions of the multiple movable plates 19 are constantly changing, and the multiple springs 18 are compressed, so the multiple movable columns 15 drive the corresponding resistance blocks 14 to lift the tough sealing ring 8, so that the tough sealing ring 8 is close to the inner wall of the end of the screw hole, and then press the card block 13 to move the card block 13 downward so that it is located between the two nearest blocking plates 20 and fits with the blocking plates 20, so as to limit the handle 12, and at this time the inner sealing ring 9 is close to the wall, and then the internal threaded tube 6 is reset and tightened, so that the threaded tube 6 drives the outer sealing ring 7 to approach the inner sealing ring 9, squeezes the inner sealing ring 9, and forms a multiple blocking effect.
