[0025] Combined with Figure 1 , Attachment Figure 2 , Attachment Figure 3 As shown, a building expansion joint waterproof structure comprises two building walls 1, an expansion joint 2 is arranged between the two building walls 1, a waterproof coiled material 3 is laid on the building wall 1, one end of the waterproof coiled material 3 extends into the expansion joint 2, three U-shaped plates 4 are arranged in the expansion joint 2, sleeves 5 are arranged on both sides of the U-shaped plate 4, a sliding column 6 is slidably arranged in the sleeve 5, a fixed plate is arranged at one end of the sliding column 6, the fixed plate is abutted against the building wall 1, and an adjustment mechanism 7 is provided on the U-shaped plate 4 to make the sliding column 6 close to the building wall 1;

[0026] The waterproof membrane 3 is slidably provided with sliders 27 on both sides of the expansion joint 2, one end of the slider 27 is an arc-shaped surface, and the arc-shaped surface faces the outside of the expansion joint 2. A drainage groove 37 is provided below the slider 27 on the building wall 1, and a triangular plate 8 is slidably provided on the slider 27. A plurality of fixed blocks 35 are provided on the slider 27, and a slide groove 2 cooperating with the fixed block 35 is provided on the bottom surface of the triangular plate 8. A spring 5 36 is provided between the fixed block 35 and the inner wall of the slide groove 2, and a synchronization mechanism 9 is provided between the slider 27 and the slide column 6, which drives the slider 27 to move synchronously with the slide column 6.

[0027] Working principle: In the initial state, the spring 5 36 is in a relaxed state. The three U-shaped plates 4 are placed in the expansion joint 2 to a suitable position. The fixed plate at one end of the slide column 6 is made to be in close contact with the building wall 1 through the adjustment mechanism 7. The slider 27 is placed on the expansion joint 2. The slider 27 is connected to the slide column 6 through the synchronization mechanism 9. At this time, the installation is completed. When it rains, rainwater will fall on the triangular plate 8 and then on the slider 27. Since the surface of the slider 27 is an arc, rainwater will not enter the expansion joint 2 from between the triangular plate 8 and the slider 27. Then, the rainwater falls from the slider 27 to the waterproof membrane 3. When the rainwater enters between the slider 27 and the waterproof membrane 3, it will fall into the drainage trough 37 and then be discharged, thereby achieving a waterproof effect.

[0028] When the expansion joint 2 contracts or expands, the building wall 1 will move, and the adjustment mechanism 7 will push the sliding column 6 to move, so that the fixed plate at one end of the sliding column 6 is always in close contact with the building wall 1, and then the sliding column 6 drives the slider 27 to slide through the synchronization mechanism 9, and the slider 27 extends outward or inward. Since one end of the slider 27 is an arc surface, during the movement, rainwater cannot enter the expansion joint 2 from the gap between the slider 27 and the triangular plate 8, and part of the rainwater entering from between the waterproof membrane 3 and the slider 27 will be discharged through the drainage groove 37.

[0030] Working principle of adjustment mechanism 7: In the initial state, spring 11 is in a relaxed state, then the fixing plate is squeezed, spring 11 is compressed, and then the U-shaped plate 4 is placed in the expansion joint 2 to a suitable position, the fixing plate is loosened, and spring 11 pushes the fixing plate to move, the fixing plate fits the surface of the building wall 1, and the U-shaped plate 4 is located in the middle position of the expansion joint 2, and then the threaded sleeve 15 is rotated, the threaded sleeve 15 moves downward, thereby driving the ring 14 to move downward, and the ring 14 drives the connecting column 10 to slide in the sleeve 5 through the connecting rod 12, the spring 11 is compressed, and the threaded sleeve 15 stops after rotating a suitable number of circles. At this time, the fixation is completed, and then the above operation is followed to complete the fixation of the other two U-shaped plates 4.

[0033] Working principle of synchronization mechanism 9: In the initial state, spring 24 is in a compressed state, and torsion spring 39 is in a relaxed state. When U-shaped plate 4 is fixed, slide block 27 is lifted, and driving mechanism 21 is moved to make block 20 slide, so as not to block fixed rod 18 from entering the slot. Then, the slot on slide block 27 is aligned with fixed rod 18. During the lowering process of slide block 27, fixed rod 18 enters the slot. When the top of fixed rod 18 fits with the top surface of the slot, drive mechanism 21 is released, and drive mechanism 21 drives block 20 to slide, and block 20 enters the slot 19, completing the alignment between slide block 27 and fixed rod 18.

Under the gravity of the triangular plate 8 and the slider 27 and the elastic force of the spring 24, the slider 27 is tightly fitted with the waterproof membrane 3 to complete the fixation of the slider 27. When the expansion joint 2 expands or contracts, the building wall 1 moves, the sliding column 6 moves with the building wall 1, the sliding column 6 drives the extension rod 16 to move, the extension rod 16 drives the fixing rod 18 to move, and the fixing rod 18 drives the slider 27 to move.

[0034] Combined with Figure 1 , Attachment Figure 3 , Attachment Figure 7 As shown, the driving mechanism 21 includes a plug post 28 movably plugged into the slider 27, a spring 29 is provided between the plug post 28 and the slider 27, a connecting block 30 is provided at one end of the clamping block 20, and the other end of the connecting block 30 is fixedly connected to the plug post 28.

[0035] Working principle of driving mechanism 21: in the initial state, spring three 29 is in a relaxed state, pressing the plug post 28, spring three 29 is compressed, the plug post 28 drives the connecting block 30 to move, and the connecting block 30 drives the clamping block 20 to move, so as not to hinder the fixing rod 18 from entering the slot. When the end of the fixing rod 18 is in contact with the top surface of the slot, release the plug post 28, spring three 29 pushes the plug post 28 to reset, and the clamping block 20 enters the clamping slot 19, completing the fixation of the fixing rod 18 and the slider 27.

[0036] Combined with Figure 1 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 7 As shown, the transmission mechanism 38 includes a driving block 31 slidably set in the slot 19, one side of the driving block 31 is arc-shaped, an extension column 32 is provided on the bottom surface of the driving block 31, a spring 33 is provided between the end of the extension column 32 and the driving block 31, and an L-shaped plate 34 passing through a sliding hole is provided at one end of the extension column 32, and the L-shaped plate 34 abuts against the wedge-shaped structure at the end of the push rod 25.

[0037] The working principle of the transmission mechanism 38 is as follows: in the initial state, the spring four 33 is in a relaxed state. When the card block 20 enters the card slot 19, the card block 20 contacts the driving block 31 and then pushes the driving block 31 to move downward. The spring four 33 is compressed, and the driving block 31 drives the extension column 32 to move downward. The extension column 32 drives the L-shaped plate 34 to move downward. The downward movement of the L-shaped plate 34 drives the push rod 25 to rotate through the wedge-shaped structure, so that the limit plate 26 on the push rod 25 is separated from the extension plate 22.

[0038] In specific use, first, a drainage groove 37 is opened on the building wall 1, and then the waterproof membrane 3 is laid, and then the three U-shaped plates 4 are respectively placed in the expansion joint 2, and the fixing plate is made close to the building wall 1 through the adjustment mechanism 7, and then the slider 27 is placed, and the slot on the slider 27 is aligned with the fixing rod 18, and then the block 20 is clamped in the slot 19 through the driving mechanism 21, and the push rod 25 is rotated through the transmission mechanism 38, so that the spring 24 pushes the fixing rod 18 to move downward, so that the slider 27 is close to the surface of the waterproof material. At this time, the installation is completed. When it rains, rainwater falls on the triangular plate 8, then falls on the arc surface of the slider 27, and then falls on the waterproof membrane 3. For part of the rainwater entering between the slider 27 and the waterproof membrane 3, it is discharged through the drainage groove 37. When the expansion joint expands and contracts, the sliding column 6 will move accordingly, and be synchronized to the slider 27 through the synchronization mechanism 9, so that the slider 27 moves accordingly, thereby adapting to expansion joints 2 of different widths.
