Description

Technical Field

[0001] The utility model relates to the technical field of water-stop screw rods, in particular to a water-stop screw rod which is convenient for assembly and disassembly. Background Art

[0002] At present, underground structure penetration has always been a very troubling problem. In concrete structure construction, the penetration problem is also very prominent. Waterstop screws are generally used in the pouring of shear walls and civil defense walls to fix the formwork and serve as a formwork reinforcement tool to control the thickness of concrete pouring.

[0003] Chinese patent publication number CN210483052U discloses a seven-section water-stop screw, including an externally connected turnover rod, which is a long circular rod and has two groups of externally connected turnover rods, which are distributed at both ends of the entire device, and the two groups of externally connected turnover rods are fixedly installed with screws at the ends away from each other, and the screws are sleeved with mountain-shaped cards, which are equipment for fastening building casting templates, and the mountain-shaped cards have a mountain-shaped appearance, and a circular through hole is horizontally opened in the middle of the mountain-shaped cards, and the two groups of mountain-shaped cards are sleeved on the two groups of screws through the circular through holes in a mountain-shaped manner facing each other, and the two ends of the two groups of screws are threadedly connected with fixing nuts, which are used to fix the entire device, and the two groups of externally connected turnover rods are far away from each other. A connecting cylinder is arranged on the screw side, and the connecting cylinder is a hollow cylinder and an internal thread is arranged on the inner wall on the right side of the connecting cylinder. The external circulating rod is inserted into the inside of the connecting cylinder by external stamping, and a main rod is horizontally arranged in the middle position of the two groups of the external circulating rods. The main rod is a cylindrical long rod. Although the water-stop screw can squeeze the mountain-shaped card by rotating the fixing nut, the mountain-shaped card squeezes the wall to fix the entire water-stop screw. The external circulating rod and the conical sleeve are connected separately to form a whole, which can be disassembled for easy turnover, simplifying the difficulty of using the equipment and making the water-stop screw more convenient to use. However, the length of common water-stop screws is mostly fixed, which is not easy to adjust and has low adaptability, so it needs to be improved. Utility Model Content

[0011] Preferably, the support frames are distributed in a circumferential array on the surface of the water stop plate, and the reinforcing ribs are made of martensitic stainless steel. Here, martensitic stainless steel has high hardness and wear resistance and can provide high support.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, when installing the water stop screw, first take out the screw body, then hold the conical pad, make the conical pad opposite to one end of the screw body, and rotate the conical pad. Since the conical pad and the screw body are threadedly connected, the conical pad moves toward the water stop plate until the conical pad moves to the innermost end. At this time, the conical pad is installed on the other end of the screw body, and then the handle is picked up, the hand is inserted into the groove, the handle is held, and the sleeve is opposite to the screw body, and the connecting block is opposite to the connecting port. At this time, the handle is rotated, the handle drives the sleeve to rotate, the sleeve drives the connecting block to move, and the connecting block then enters the connecting port. In the interface, since the connecting block and the connecting port are meshed, the connecting block moves along the thread toward the inside of the connecting port. At the same time, the sleeve is threadedly connected to the surface of the screw body, so the sleeve moves on the surface of the screw body until the connecting block completely enters the connecting port. At this time, the sleeve can be installed on the other end of the screw body. In the utility model, the length of the water-stop screw is conveniently adjusted by arranging the turning handle, the sleeve, the connecting port and the connecting block. The position of the sleeve on the surface of the screw body can be adjusted by turning the turning handle, thereby improving the adaptability of the water-stop screw. At the same time, the water-stop screw can also be conveniently disassembled, thereby improving portability. The structure is simple and practical.

[0014] 2. In the utility model, when the screw body is placed in concrete, the concrete will more or less squeeze the screw body. At this time, the support frame and the reinforcing ribs can increase the supporting strength of the screw body to prevent the screw body from breaking, thereby improving the service life of the screw body to a certain extent and reducing the cost of use.

[0028] Embodiment 2

[0029] See also Figure 5-6 A support frame 11 is fixedly installed on the surface of the water stop plate 2, and a reinforcing rib 12 is fixedly installed on the surface of the support frame 11. One end of the support frame 11 is fixedly connected to the water stop plate 2, and the other end of the support frame 11 is fixedly connected to the screw body 1, which can improve the strength of the screw body 1 and prevent breakage. The support frame 11 is distributed in a circular array on the surface of the water stop plate 2, which protects the water stop plate 2 and reduces the probability of breakage of the water stop plate 2. The material of the reinforcing rib 12 is martensitic stainless steel. Martensitic stainless steel has high hardness and wear resistance, and can provide better support effect, thereby extending the service life of the water stop plate 2 and the screw body 1.

[0030] Working principle: When installing the water-stop screw, first take out the screw body 1, and then hold the conical pad 3, so that the conical pad 3 is opposite to one end of the screw body 1, and rotate the conical pad 3. Since the conical pad 3 and the screw body 1 are threadedly connected, the conical pad 3 moves toward the water-stop plate 2 until the conical pad 3 moves to the innermost end. At this time, install the conical pad 3 on the other end of the screw body 1, and then pick up the turning handle 6, insert the hand into the groove 9, hold the turning handle 6, and then make the sleeve 5 opposite to the screw body 1, and make the connecting block 8 opposite to the connecting port 4. At this time, rotate the turning handle 6, the turning handle 6 drives the sleeve 5 to rotate, and the sleeve 5 drives the connecting block 8 to move, and the connecting block 8 then enters the connecting port 4. Since the connecting block 8 and the connecting port 4 are meshed, the connecting block 8 moves along the thread toward the inside of the connecting port 4. At the same time, the sleeve 5 and the surface of the screw body 1 are threadedly connected, so the sleeve 5 moves on the surface of the screw body 1 until the connecting block 8 completely enters the connecting port 4. At this time, the sleeve 5 can be installed on the other end of the screw body 1. When disassembling the water-stop screw, it is only necessary to manually rotate the handle 6, the handle 6 drives the sleeve 5 to move, the sleeve 5 drives the connecting block 8 to move, and the connecting block 8 then moves in the opposite direction along the thread from the connecting port 4. At the same time, the sleeve 5 moves in the opposite direction on the surface of the screw body 1 until the connecting block 8 is separated from the connecting port 4. At this time, the sleeve 5 is also separated from the surface of the screw body 1. Then the conical pad 3 is rotated and the conical pad 3 is removed from the surface of the screw body 1 to complete the disassembly. When the screw body 1 is placed in concrete, the concrete will more or less squeeze the screw body 1. At this time, the support frame 11 and the reinforcing ribs 12 can increase the supporting strength of the stop screw body 1 to prevent the screw body 1 from breaking, thereby improving the service life of the screw body 1 to a certain extent.
