Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of drainage devices, and more specifically, it relates to a drainage device for treating leakage in expansion joints. Background Technology
[0002] Expansion joints are a general term encompassing expansion joints, settlement joints, and seismic joints. Buildings often deform under external influences, leading to cracking and even damage. Expansion joints are structural joints designed to address this. Expansion joints are structural joints designed to prevent the expansion and contraction of building components due to changes in temperature and humidity. To address this, vertical gaps are typically installed at appropriate locations within the building, separating the walls, floors, roof, and other structural components above the foundation, thus dividing the building into several independent parts. Joints designed to overcome excessive temperature differences may not require interruption of the foundation; instead, they may be installed along the structural line from the top of the foundation to the roof.
[0003] Currently, the construction process for expansion joints involves numerous steps, making quality control difficult. Leakage frequently occurs after the top slab backfilling is completed, and repeated treatments are often insufficient to completely eliminate the problem. Leakage repair is costly, and the intercepting channels are typically fixed beneath the installation, making disassembly extremely difficult and impacting worker efficiency. Furthermore, water flowing into the intercepting channels may contain impurities, which can hinder drainage. Therefore, a leakage interception and diversion device for expansion joints is needed.

The diversion device includes a structural beam, a fixed rod fixedly connected to the lower surface of the structural beam, an angle steel bracket slidably connected to the outer surface of the fixed rod, a groove inside the fixed rod, a sliding groove on the inner side wall of the groove, a sliding plate slidably connected to the inner wall of the sliding groove, a first spring fixedly connected to one side of the sliding plate, one side of the first spring fixedly connected to the groove, a water interception groove connected to the lower surface of the angle steel bracket by bolt thread, an inclined plate fixedly connected to the upper surface of the water interception groove, and a limit block fixedly connected to one side of the sliding plate.

[0013] (III) Beneficial Effects

[0015] 1. By setting a fixed rod, the angle steel bracket slides on the outer surface of the fixed rod.

[0016] 2.

[0026] Please see Figures 1-5 A leakage interception and diversion device for expansion joints includes a structural beam 1. A fixed rod 2 is fixedly connected to the lower surface of the structural beam 1. An angle steel bracket 3 is slidably connected to the outer surface of the fixed rod 2. A groove is formed inside the fixed rod 2. A sliding groove is formed on the inner side wall of the groove. A sliding plate 4 is slidably connected to the inner wall of the sliding groove. A first spring 5 is fixedly connected to one side of the sliding plate 4. One side of the first spring 5 is fixedly connected to the groove. A water interception groove 6 is connected to the lower surface of the angle steel bracket 3 by bolt thread. An inclined plate 7 is fixedly connected to the upper surface of the water interception groove 6. A limit block 17 is fixedly connected to one side of the sliding plate 4.
[0027] Specifically, by setting the fixed rod 2, the angle steel bracket 3 slides on the outer surface of the fixed rod 2, and the elasticity of the first spring 5 causes the limiting block 17 to extend and retract within the fixed rod 2. Then the limiting block 17 limits and fixes the angle steel bracket 3, which facilitates the disassembly of the water interception channel 6 and the maintenance of the water interception channel 6. This can effectively solve the problem of deformation joint leakage that is difficult to deal with after delivery.
[0028] Please see Figures 1-5A water outlet pipe 8 is fixedly connected to the lower surface of the water intercepting trough 6. A circular groove 9 is formed on the upper surface of the water intercepting trough 6. An installation rod 10 is fixedly connected to the upper surface of the circular groove 9. A placement groove is formed on the inner wall of the installation rod 10. A sliding groove is formed on the inner wall of the placement groove. A moving plate 11 is slidably connected to the inner wall of the sliding groove. A second spring 12 is fixedly connected to one side of the moving plate 11. One side of the second spring 12 is fixedly connected to the placement groove. A locking block 13 is fixedly connected to one side of the moving plate 11. An installation ring 14 is slidably connected to the outer surface of the installation rod 10. A filter screen 15 is fixedly connected to one side of the installation ring 14. A locking groove 16 is formed on the upper half surface of the installation ring 14.
[0029] Specifically, through the setting of the water interception trough 6, and the cooperation between the water outlet pipe 8, circular groove 9, mounting rod 10, moving plate 11, second spring 12, locking block 13, mounting ring 14, filter screen 15 and locking groove 16, the filter screen 15 filters impurities from the water outlet pipe 8. Then, by pressing the locking block 13 inward, the locking block 13 is retracted into the mounting rod 10, and the mounting ring 14 and filter screen 15 can be disassembled for easy cleaning and replacement, thus addressing the problem of leakage in the expansion joint.
[0030] In summary, when the entire equipment is in use: The fixed rod 2 is used, and the angle steel bracket 3 slides on the outer surface of the fixed rod 2. The elasticity of the first spring 5 causes the limiting block 17 to extend and retract within the fixed rod 2. The limiting block 17 then limits and fixes the angle steel bracket 3, facilitating the disassembly and maintenance of the intercepting trough 6. This effectively solves the problem of leakage from expansion joints that is difficult to handle after delivery. The intercepting trough 6, through the coordinated arrangement of the outlet pipe 8, circular groove 9, mounting rod 10, moving plate 11, second spring 12, locking block 13, mounting ring 14, filter screen 15, and locking groove 16, further enhances the overall functionality. First, by pressing the locking block 13 inward, the locking block 13 is retracted into the mounting rod 10. Then, the mounting ring 14 with the filter screen 15 is slid out from the outer surface of the mounting rod 10. The filter screen 15 is then disassembled for cleaning or replacement. After that, the new filter device is installed into the circular groove 9 through the mounting rod 10. Then, the elasticity of the second spring 12 drives the moving plate 11 and the locking block 13 to move, fixing the mounting ring 14. This makes it easy to disassemble the mounting ring 14 and the filter screen 15. The filter screen 15 filters impurities from the water outlet pipe 8, making it easy to clean and replace, and to address the problem of leakage in the expansion joint.
