Description
Technical Field
[0001] The utility model relates to the technical field of boiler flue gas monitoring, and particularly relates to a steel plate water stop belt structure. Background Technique
[0002] Steel plate water stop belt: also known as water stop steel plate; in a box foundation or basement, the concrete of the floor slab, exterior wall slab, and roof slab is poured separately. When pouring the wall slab concrete next time, there will be a construction cold joint. When the position of this joint is below the groundwater level line, water seepage is likely to occur. Therefore, this joint needs to be technically treated. There are many treatment methods, and the more common method is to set a water stop steel plate. The connection between the steel plate water stop belts is usually achieved by overlapping two steel plate water stop belts and then fixing the two steel plate water stop belts by means of bolt fastening or rivet anchoring to complete their connection. However, this method requires pre-drilling holes in the steel plate water stop belt, and it is not easy to control the size and position accuracy. There are large errors or variables during construction and installation, and the risk of water seepage at the bolt holes is relatively high. For this reason, we propose a steel plate water stop belt structure. Content of the Utility Model
[0003] The utility model provides a steel plate water stop belt structure, which solves the problems raised in the above background technique.
[0004] To achieve the above object, the utility model is realized through the following technical solutions: a steel plate water stop belt structure, including steel plate water stop belts, two steel plate water stop belts overlap each other. Corrugated connecting parts are arranged on the inner side of one end of the steel plate water stop belt and the outer side of the other end of the steel plate water stop belt. The connecting parts on the two steel plate water stop belts correspond to and fit with each other. A threaded column is fixedly installed near the middle of the steel plate water stop belt. The threaded column passes through the overlapping steel plate water stop belt, and a connecting nut is connected to the end of the threaded column passing through the steel plate water stop belt.
[0005] Optionally, an annular lock is fixedly connected to the steel plate water stop belt corresponding to the threaded column. The threaded column passes through the middle of the annular lock, and inclined ratchet teeth are provided on the side of the annular lock close to the threaded column.
[0006] Optionally, a limiting lock ring is movably connected to the side of the connecting nut close to the annular lock. The limiting lock ring is hollow, and the threaded column passes through the middle of the limiting lock ring and is threadedly connected to the connecting nut.
[0007] Optionally, a limiting spring is fixedly connected to the side of the limiting lock ring close to the inside of the connecting nut. One end of the limiting spring is fixedly connected to the inside of the connecting nut.
[0008] Optionally, ratchet teeth staggered with the threaded column are provided on the side of the limiting lock ring close to the annular lock, and the threaded column is engaged with the limiting lock ring.
[0009] Optionally, a connection positioning plate is fixedly connected to the inner side of the steel plate waterstop, and one side of the connection positioning plate abuts against one side of another overlapping steel plate waterstop.
[0010] The utility model has the following beneficial effects:
[0011] 1. For the structure of the steel plate waterstop, through the corrugated connection mode between the connecting parts, the connection length between them can be extended, so that their connection is tighter, the waterproof effect is better, and through the threaded posts fixed on the steel plate waterstop, the steel plate waterstops can be fixed, and the holes through which the threaded posts pass are close to the connection positioning plate, so that the flow path still needs to pass through the corrugated path between the steel plate waterstops, thus making the waterproof effect better.
[0012] 2. For the structure of the steel plate waterstop, by restricting the movement of the limiting lock ring, the connecting nut can be smoothly screwed and installed with the threaded post, and under the action of the spring force of the limiting spring, the limiting lock ring can finally engage with the annular lock catch, thereby locking the position of the connecting nut and preventing the connecting nut from loosening during vibration, so that the connection between them is more firm.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0020] Please refer to Figures 1 to 5 , a steel plate waterstop structure, including a steel plate waterstop 1. Two steel plate waterstops 1 overlap each other. Corrugated connecting parts 6 are provided on the inner side of one end of the steel plate waterstop 1 and the outer side of the other end of the steel plate waterstop 1. The connecting parts 6 on the two steel plate waterstops 1 correspond to and fit each other. Through the corrugated connection method between the connecting parts 6, the connection length between them can be extended, thereby making their connection tighter and the waterproof effect better. A threaded post 2 is fixedly installed near the middle of the steel plate waterstop 1. The threaded post 2 passes through the overlapping steel plate waterstop 1, and a connecting nut 4 is connected to one end of the threaded post 2 passing through the steel plate waterstop 1. Through the connection between the threaded post 2 and the connecting nut 4, the two steel plate waterstops 1 can be fixed to each other. And the position of the threaded post 2 makes the position where the threaded post 2 passes through be at the end of the connection between the steel plate waterstops 1. The flow path through the threaded post 2 still needs to pass through the corrugated path between the steel plate waterstops 1, so as to make the waterproof effect better.
[0021] Please refer to Figures 1 to 4 , an annular lock 5 corresponding to the threaded post 2 is fixedly connected to the steel plate waterstop 1. The threaded post 2 passes through the middle of the annular lock 5, and inclined ratchet teeth are provided on one side of the annular lock 5 close to the threaded post 2.
[0022] Please refer to Figures 1 to 4 , a limiting lock ring 7 is movably connected to one side of the connecting nut 4 close to the annular lock 5. The limiting lock ring 7 can move along a fixed track inside the connecting nut 4. Then when the connecting nut 4 is screwed, the limiting lock ring 7 can contact the annular lock 5, and then the limiting lock ring 7 can move relative to the connecting nut 4. The limiting lock ring 7 is hollow, and the threaded post 2 passes through the middle of the limiting lock ring 7 and is threadedly connected to the connecting nut 4, so that the connecting nut 4 can be smoothly screwed and installed on the threaded post 2.
[0023] Please refer to Figures 1 to 4, a limiting locking ring 7 is fixedly connected to the side close to the inside of the connecting nut 4, and one end of a limiting spring 8 is fixedly connected to the inside of the connecting nut 4. Under the action of the elastic force of the limiting spring 8, the limiting locking ring 7 can always be in contact with the annular locking buckle 5, and when the connecting nut 4 is installed, the limiting spring 8 can push the limiting locking ring 7 to engage with the annular locking buckle 5, giving the connecting nut 4 a locking force against reverse rotation, so that the installation of the connecting nut 4 is more firm.
[0024] Please refer to Figures 1 to 5 , on the side of the limiting locking ring 7 close to the annular locking buckle 5, there are ratchet teeth staggered with the threaded post 2, and the threaded post 2 is engaged with the limiting locking ring 7. Through the limitation between the limiting locking ring 7 and the annular locking buckle 5, when the connecting nut 4 rotates, the connecting nut 4 will drive the limiting locking ring 7 to rotate, and then through the limitation of the limiting locking ring 7, the connecting nut 4 is locked.
[0025] Please refer to Figures 1 to 5 , a connecting positioning plate 3 is fixedly connected to the inner side of the steel plate waterstop 1, and one side of the connecting positioning plate 3 abuts against one side of another overlapping steel plate waterstop 1. Through the abutment of the connecting positioning plate 3, the overlapping connection length between the steel plate waterstops 1 can be determined, so that the connection between the steel plate waterstops 1 is more standardized, and under the action of the connecting positioning plate 3, it can play a role in extending its flow path, thus playing a certain waterproof effect.
[0026] In summary, for this steel plate waterstop structure, during use, one end of the steel plate waterstop 1 is opposed to and in contact with the connecting positioning plate 3 on another steel plate waterstop 1, and then the connecting part 6 on the steel plate waterstop 1 is overlapped and fitted. The threaded post 2 passes through another steel plate waterstop 1, and then the connecting nut 4 is screwed onto the threaded post 2. The connecting nut 4 is gradually screwed onto the threaded post 2, and the limiting locking ring 7 is in contact with the annular locking buckle 5. As the connecting nut 4 is screwed, the limiting locking ring 7 moves relatively inside the connecting nut 4. When the connecting nut 4 is fully screwed, the limiting locking ring 7 engages with the annular locking buckle 5, thereby limiting the connecting nut 4.
