Description

Technical Field

[0001] The present application relates to the field of waterstops, and more specifically, to a waterstop structure for a bridge expansion joint. Background Art

[0002] In order to meet the requirements of bridge deck deformation, expansion joints are usually set between the two beam ends, between the beam ends and the abutments, or at the hinged positions of the bridges, and waterstops need to be set in the expansion joints. The main function of the waterstops is to prevent water leakage when the building is subjected to deformation and vibration. It prevents water and other liquids from penetrating into the building by filling the gaps between the expansion joints. The patent document with the prior art publication number CN214831887U provides a bridge expansion joint waterstop structure. The device filters sand and gravel through the filter plate, so that rainwater flows into the drainage system from the filter holes and sand and gravel accumulate at the filter plate, preventing sand and gravel from entering the drainage system with rainwater and causing system blockage, thereby improving the practicality of the device.

[0003] With respect to the above-mentioned related technologies, the inventor believes that since filter plates are provided at both ends of the first waterstop body, the intercepted sand and gravel will accumulate in the first waterstop body and cannot be discharged, thereby rendering the first waterstop body ineffective and requiring increased maintenance frequency, which is not practical. Therefore, we propose a bridge expansion joint waterstop structure. Utility Model Content

[0004] In order to improve the problems raised in the above background technology, the present application provides a bridge expansion joint waterstop structure, which adopts the following technical solutions:

[0005] A waterstop structure for a bridge expansion joint includes a waterstop body, both ends of the waterstop body are fixedly connected to limit strips A, a plurality of through holes are opened in the middle of the waterstop body, and a drainage groove is provided on the lower side of the waterstop body, connecting strips are snap-fitted on both sides of the drainage groove, the connecting strips are fixedly connected to the waterstop body, a plurality of water guide plates are fixedly connected to the drainage groove, and the plurality of water guide plates are all arranged at an angle.

[0006] By adopting the above technical solution, after the waterstop body is installed in the expansion joint, rainwater and sediment on the bridge deck fall on the waterstop body and flow into the drainage trough through the through holes. The rainwater can wash away the sediment accumulated at the bottom of the drainage trough under the guidance of the water guide plate, so that the sediment can flow to both sides of the drainage trough faster, preventing the sediment from accumulating in the drainage trough, so that the service life of the waterstop body can be extended.

[0007] Optionally, one end of the connecting belt is fixedly connected to a limit strip B, and both sides of the drainage groove are fixedly connected to clamping grooves, and the limit strip B is clamped and matched with the clamping grooves.

[0008] By adopting the above technical solution, after the limit strip B is engaged with the card slot, the drainage groove is installed below the through hole of the waterstop belt body, and can be used to receive rainwater and sediment discharged from the waterstop belt body.

[0009] Optionally, a plurality of reinforcement rods are fixedly connected at equal intervals in the drainage trough.

[0010] By adopting the above technical solution, when the bridge drives the waterstop body to stretch, the connecting belt drives the drainage trough to deform. Under the limitation of the reinforcement rod, the drainage trough can be prevented from being deformed and damaged. At the same time, the strength of the waterstop body can be increased to avoid tearing when the through holes of the waterstop body are subjected to force.

[0011] Optionally, the plurality of water guide plates are arranged in two groups symmetrically and at equal intervals.

[0012] By adopting the above technical solution, after rainwater flows onto the water guide plate, under the inclined guidance of the water guide plate, the rainwater can flush the sediment accumulated at the bottom of the drainage trough to the two ports, so that the sediment can be discharged quickly.

[0013] Optionally, both ends of the drainage trough are fixedly connected with fixed plates, and the lower side of the fixed plate is provided with a baffle plate rotatably connected to the drainage trough.

[0014] By adopting the above technical solution, when there is rainwater in the drainage trough, the baffle can be driven to automatically open outward to drain rainwater and sediment. When the drainage trough is not draining, the baffle will close the drainage trough port under the action of gravity to prevent external foreign matter from entering the drainage trough.

[0015] In summary, the present application includes at least one of the following beneficial technical effects:

[0016] 1. When rainwater and sediment on the bridge deck flows onto the waterstop body, they can flow into the drainage trough through the through holes. Under the action of the guide plate, the rainwater can wash away the sediment accumulated at the bottom of the drainage trough, so that the sediment can be quickly discharged to both ends of the drainage trough, thereby avoiding the waterstop body from losing its function, prolonging the service life of the waterstop body, reducing the maintenance frequency, and having good practicality.

[0017] 2. When the drainage trough is not draining, the baffles at both ends close the port under the action of gravity, which can prevent external foreign matter from entering the drainage trough, thereby ensuring the drainage efficiency of the drainage trough. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present application is further described in detail below in conjunction with the accompanying drawings.

[0023] Reference Figure 1-3 The present application includes a waterstop body 1, both ends of which are fixedly connected to limit strips A2, a plurality of through holes 3 are opened in the middle of the waterstop body 1, and a drainage groove 4 is provided on the lower side of the waterstop body 1, and connecting strips 5 are snap-fitted on both sides of the drainage groove 4, and the connecting strips 5 are connected and fixed to the waterstop body 1, and a plurality of water guide plates 9 are fixedly connected to the drainage groove 4, and the plurality of water guide plates 9 are all inclinedly arranged. After the waterstop body 1 is installed in the expansion joint, rainwater and sediment on the bridge deck fall on the waterstop body 1 and flow into the drainage groove 4 through the through holes 3. The rainwater can wash away the sediment accumulated at the bottom of the drainage groove 4 under the guidance of the water guide plate 9, so that the sediment can flow to the two sides of the drainage groove 4 faster, preventing the sediment from accumulating in the drainage groove 4, so that the service life of the waterstop body 1 can be extended.

[0024] Reference Figure 2 One end of the connecting belt 5 is fixedly connected to a limiting strip B6, and both sides of the drainage groove 4 are fixedly connected to a slot 7. The limiting strip B6 is engaged with the slot 7. After the limiting strip B6 is engaged with the slot 7, the drainage groove 4 is installed below the through hole 3 of the waterstop belt body 1, and can be used to receive rainwater and sediment discharged from the waterstop belt body 1.

[0025] Reference Figure 3 There are multiple reinforcement rods 8 fixedly connected at equal intervals in the drainage groove 4. When the bridge drives the waterstop belt body 1 to stretch, the drainage groove 4 is deformed by the connecting belt 5. Under the restriction of the reinforcement rod 8, the drainage groove 4 can be prevented from being deformed and damaged. At the same time, the strength of the waterstop belt body 1 can be increased to avoid tearing when the through hole 3 of the waterstop belt body 1 is subjected to force.

[0026] Reference Figure 3 The plurality of water guide plates 9 are arranged in two groups symmetrically and at equal intervals. After the rainwater flows onto the water guide plates 9, the rainwater can flush the sediment accumulated at the bottom of the drainage trough 4 toward the two ports under the inclined guidance of the water guide plates 9, so that the sediment can be discharged quickly.

[0027] Reference Figure 3Both ends of the drainage trough 4 are fixedly connected with a fixing plate 10, and a baffle 11 rotatably connected to the drainage trough 4 is provided on the lower side of the fixing plate 10. When there is rainwater in the drainage trough 4, the baffle 11 can be driven to automatically open outward to drain rainwater and sediment. When the drainage trough 4 does not drain water, the baffle 11 is closed at the port of the drainage trough 4 under the action of gravity to prevent external foreign matter from entering the drainage trough 4.

[0028] The implementation principle of a bridge expansion joint waterstop structure in an embodiment of the present application is as follows: the waterstop body 1 is installed and connected to the expansion joint connector through a limit strip A2. When rainwater and sediment on the bridge deck flow onto the waterstop body 1, they flow into the drainage ditch 4 through the through hole 3. The rainwater changes its flow direction when passing through the guide plate 9, so that it flushes the sediment accumulated at the bottom of the drainage ditch 4 and is quickly discharged to both ends.
