Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figure 1 , 2 shown, a waterproof structure for a building structure expansion joint includes: a positioning mechanism 1, the positioning mechanism 1 is arranged at the top of the expansion joint, the positioning mechanism 1 includes a reaction plate 11, and the reaction plate 11 is arranged on both sides of the expansion joint; a locking mechanism 2, the locking mechanism 2 is connected to the reaction plate 11 through a spring 211, and the bottom of the locking mechanism 2 presses against the side wall of the expansion joint; a sealing mechanism 3, the sealing mechanism 3 is arranged in the expansion joint, the sealing mechanism 3 includes a waterstop belt 31, and the waterstop belt 31 is arranged at the bottom of the locking mechanism 2; a cover plate mechanism 4, the cover plate mechanism 4 is arranged above the expansion joint, and the cover plate mechanism 4 is detachably connected to the positioning mechanism 1.

[0024] The positioning mechanism 1 further includes a slideway plate 12, a pressing strip 13, and a counterweight 14. The slideway plate 12 is arranged above the expansion joint, both sides of the slideway plate 12 are erected on the floor on the side of the expansion joint, several slideways are opened on the slideway plate 12, the pressing strip 13 is arranged on both sides of the slideway plate 12, the counterweight 14 is arranged at both ends of the pressing strip 13, the counterweight 14 provides gravity to fix the positions of the pressing strip 13 and the slideway plate 12, the reaction plate 11 is arranged between the two pressing strips 13, and the bottom of the reaction plate 11 is located above the plate surface.

[0025] The top of the counterweight block 14 is a threaded rod 141. The threaded rod 141 penetrates through the pressing strip 13. A fastening button 142 is screwed on the upper end of the threaded rod 141. The gravity of the counterweight block 14 is large and its position is fixed, and the counterweight block 14 will not pierce the waterproof coiled material 411 on the roof surface, preventing water from seeping into the roof through the holes. By turning the fastening button 142 to press the pressing strip 13, the slideway plate 12 fits more tightly with the floor slab surface. When settlement occurs on both sides of the expansion joint, the pressing strip 13 is bent to press the slideway plate 12 by turning the fastening button 142.

[0026] The locking mechanism 2 includes a slider 21, a compression plate 22 and a waterproof strip 23. The slider 21 is slidably connected to the slideway. The bottom surface of the slider 21 and the bottom surface of the slideway are on the same horizontal plane. The slider 21 is connected to the reaction plate 11 through a spring 211. The compression plate 22 is arranged at the bottom of the slider 21. The waterproof strip 23 is arranged on the outer wall of the compression plate 22. The spring 211 is in a stretched state. The spring 211 pulls the slider 21 and the compression plate 22 to move towards the reaction plate 11, so that the compression plate 22 drives the waterproof strip 23 to move towards the inner wall of the expansion joint and fit tightly with the expansion joint. After the compression plate 22 fits tightly with the expansion joint, the locking mechanism 2 and the positioning mechanism 1 are fixed again under the action of friction. The compression plate 22 can adapt to expansion joints of different widths. Only by pushing the slider 21 can the locking mechanism 2 and the positioning mechanism 1 be disassembled. Cooperating with the counterweight block 14 eliminates the need for bolts to pass through the waterproof coiled material 411 for fixation, improving the overall waterproof effect.

[0027] The compression plate 22 is L-shaped. The corner of the compression plate 22 fits with the corner of the expansion joint. The top surface of the compression plate 22 is arranged on the floor slab. Under the action of the pressing strip 13, the waterproof strip 23 fits tightly with the floor slab. Thus, the waterproof strip 23 is squeezed on the upper part and the top surface of the expansion joint, preventing water from flowing into the expansion joint from the side of the expansion joint.

[0028] The closing mechanism 3 further includes an installation channel 32 and a pressing rod 33. The installation channel 32 is arranged at the bottom of the compression plate 22. The length of the installation channel 32 is the same as the length of the compression plate 22. The length of the water stop belt 31 is greater than or equal to the length of the installation channel 32. Both sides of the water stop belt 31 are slidably connected to the installation channel 32. The middle part of the water stop belt 31 droops downward under the action of gravity. The water stop belt 31 can prevent the water flowing down from the slideway from continuing to flow into the expansion joint. The bottom of the pressing rod 33 presses the top of the water stop belt 31. The pressing rod 33 makes the water stop belt 31 move downward by relying on its own gravity. Thus, the side wall of the water stop belt 31 fits tightly with the installation channel 32.

[0029] The installation channel 32 is provided with a groove 321. The side wall of the water stop belt 31 penetrates into the groove 321. The opening area of the groove 321 is smaller than the inner wall area of the groove 321. Under the pressure of the pressing rod 33, the side wall of the water stop belt 31 presses the opening of the groove 321, preventing water from flowing into the expansion joint from the opening of the groove 321.

[0030] The pressing rod 33 is in an inverted T shape. The top of the pressing rod 33 penetrates through the slideway plate 12. The pressing rod 33 is slidably connected to the slideway plate 12 and can only move vertically. The gravity of the pressing rod 33 is less than the pulling force of the spring 211. When the spring 211 drives the compression plate 22 to expand to both sides, the bottom surface of the waterstop 31 that droops rises, and the waterstop 31 will drive the pressing rod 33 to rise when the opening of the groove 321 is blocked.

[0031] The cover plate mechanism 4 includes a closing plate 41, positioning pins 42 and inspection windows 43. The closing plate 41 covers the expansion joint. The positioning pins 42 penetrate through the closing plate 41 and are screwed to the pressing strip 13, thereby connecting the closing plate 41 and the pressing strip 13 into a whole. The inspection window 43 is arranged above the fastening button 142. A leak-proof plate is slidably connected to the inspection window 43. The fastening button 142 is below the inspection window 43. After settlement occurs on both sides of the expansion joint, the leak-proof plate can be opened to tighten the fastening button 142, avoiding disassembling the closing plate 41.

[0032] The side of the closing plate 41 is beveled, and waterproof coiled materials 411 are laid on the side and the surface of the closing plate 41. The waterproof coiled materials 411 seal the gap between the closing plate 41 and the floor slab, preventing water from flowing into the expansion joint from the gap between the floor slab and the closing plate 41.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
