Technical Field

[0001] This utility model belongs to the field of basement waterproofing technology, specifically relating to a waterproofing structure for basement structural joints. Background Technology

[0002] A basement is a room in a building located below the outdoor ground level. Constructing a basement below the ground floor improves land use efficiency. Some high-rise buildings have very deep foundations; utilizing this depth to build a basement offers excellent economic and practical benefits. Basements can be categorized by function (ordinary basements and air-raid shelters), by structural materials (brick and concrete), and by construction method (full basements and partial basements).

[0003] Existing basement structural waterproofing structures are prone to accidental deformation and damage to the upper fixing plate and other structures due to trampling or other reasons. Furthermore, users cannot easily observe leaks in a timely manner, thus reducing the structure's workability. In addition, the structure cannot expand the coverage area under the base slab when needed, making it difficult to adapt to different basement structures or underground conditions, thereby reducing the structure's practicality. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1 Please see Figure 1-4 The present invention provides the following technical solution: a waterproof structure for basement structural joints, including a lower fixing plate 5, the lower fixing plate 5 being disposed below a base plate 1, an upper fixing plate 7 being disposed on the top of the base plate 1, the lower fixing plate 5 and the upper fixing plate 7 being connected by a bolt assembly 4, a sealing assembly 3 being disposed between the lower fixing plate 5 and the upper fixing plate 7 and located on the inner side of the base plate 1 and the outer side of the bolt assembly 4, a protective warning device 2 being disposed above the upper fixing plate 7, and auxiliary shielding devices 6 being disposed at both ends of the lower fixing plate 5; The protection and early warning device 2 includes an annular plate 22. The annular plate 22 is arranged above the upper fixed plate 7. The protective plate 25 is arranged above the annular plate 22. An elastic rubber cylinder 24 is fixedly connected between the annular plate 22 and the protective plate 25. Multiple dampers 23 are fixedly connected between the annular plate 22 and the protective plate 25 and located inside the elastic rubber cylinder 24. An early warning component 26 is fixedly installed on the outer side of the annular plate 22.

[0018] Specifically, a threaded ring 21 is fixedly installed above the upper fixing plate 7 and inside the annular plate 22.

[0019] By adopting the above technical solution, users can connect or separate the upper fixing plate 7 and the annular plate 22 through the threaded ring 21 when needed, thereby facilitating the installation and removal of structures such as the annular plate 22 by the staff.

[0020] Specifically, an elastic rubber ring 27 is fixedly installed at the bottom of the annular plate 22.

[0021] By adopting the above technical solution, the structure can prevent gaps between the annular plate 22 and the upper fixed plate 7 through the elastic rubber ring 27, thereby reducing the possibility of water leakage and better meeting the needs of the work.

[0022] Specifically, the warning component 26 includes a transparent box 261, which is fixedly installed on the outside of the annular plate 22. Two threaded covers 262 are threadedly installed on the top of the transparent box 261, and a mesh ring 264 is fixedly installed on the bottom of the transparent box 261. Color-changing silica gel desiccant 263 is filled inside the transparent box 261 and between the two threaded covers 262 and the mesh ring 264.

[0023] By adopting the above technical solution, users can determine the leakage situation by observing the changes in the color-changing silica gel desiccant 263, which facilitates timely maintenance and better meets the needs of the work.

[0024] In this embodiment, when constructing a basement structure, the user uses bolt assembly 4 to assemble and install the sealing assembly 3, lower fixing plate 5, and upper fixing plate 7 onto the gap in the basement structure's floor slab 1. Then, the annular plate 22 in the protective warning device 2 is installed on the outside of the threaded ring 21 on the upper fixing plate 7 via threads. The damper 23 and elastic rubber cylinder 24 between the protective plate 25 and the annular plate 22 can buffer against personnel stepping on them, thereby reducing the possibility of structural deformation and damage to the upper fixing plate 7. The elastic rubber ring 27 can play an auxiliary sealing role. When there is an accidental water leak and it is about to seep into the structure, some water will pass through the mesh ring 264 in the warning assembly 26 and be absorbed by the color-changing silica gel desiccant 263 in the transparent box 261, causing the color-changing silica gel desiccant 263 to change, allowing the user to observe it in time and carry out maintenance. When necessary, the staff can unscrew the threaded cap 262 to replace the color-changing silica gel desiccant 263.

[0025] Example 2 The difference between this embodiment and embodiment 1 is that the auxiliary shielding device 6 includes a mounting plate 61, and mounting plates 61 are provided at both ends of the lower fixing plate 5. Fixing frames 64 are fixedly installed on both sides of the two mounting plates 61 that are far apart from each other. A movable block 65 is provided on the inner side of the fixing frame 64. A screw 63 is installed on one side of the movable block 65 and below the lower fixing plate 5 through a bearing.

[0026] By adopting the above technical solution, users can expand the shielding range of the structure below the base plate 1 when needed by cooperating with the screw 63 and the moving block 65, thereby better adapting to different basement structures or underground conditions.

[0027] Specifically, the inner side of the fixed frame 64 and the outer side of the movable block 65 are fitted together.

[0028] By adopting the above technical solution, the structure can prevent gaps from appearing between the inner side of the fixed frame 64 and the outer side of the moving block 65, thereby reducing the possibility of water seepage and better meeting the needs of the work.

[0029] Specifically, the lower fixing plate 5 is connected to the two mounting plates 61 by two screws 62.

[0030] By adopting the above technical solution, users can connect or separate the lower fixing plate 5 and the two mounting plates 61 with two screws 62 when needed, which facilitates the installation and removal of the two mounting plates 61 and their structures by the staff.

[0031] In this embodiment, during the assembly of the structure, the worker can connect the mounting plate 61 on the two fixed frames 64 to the lower fixed plate 5 using the two screws 62 in the auxiliary shielding device 6. Then, the worker can rotate the two screws 63 respectively. The screws 63 are threadedly connected to the fixed frames 64, and the screws 63 are bearing connected to the moving blocks 65. The outer side of the moving blocks 65 is in contact with the inner side of the fixed frames 64. Therefore, the two screws 63 drive the two moving blocks 65 to move, thereby expanding the shielding range of the structure below the base plate 1 and better adapting to different basement structures or underground conditions.

[0032] The structure and principle of the base plate 1 and its upper structure, the sealing assembly 3 composed of sealing elements, steel plates, positioning grooves, water-swellable strips and elastic metal skeleton, the bolt assembly 4 composed of countersunk holes, fastening bolts and fastening nuts, the lower fixing plate 5, and the upper fixing plate 7 of this utility model have been disclosed in a waterproof structure for basement expansion joints disclosed in announcement number CN212175873U. Its working principle is that the sealing elements, together with the steel plates and water-swellable strips, construct multiple sealing defense lines, which can effectively prevent water below the expansion joint from flowing through the expansion joint to the top of the base plate.

[0033] The structure and principle of the damper 23, which consists of a cylinder, piston rod, piston, first pressure plate, second pressure plate, damping shaft, viscous fluid, first hollow screw, second hollow screw, pressure block, spring, first outer hole, first inner hole, second outer hole, second inner hole, pressure-bearing middle part, first pressure-bearing end, second pressure-bearing end, first guide part, second guide part, shaft body, direct flow channel, first head and second head, have been disclosed in the speed-adjustable damper disclosed in announcement number CN215673334U. Its working principle is that a uniform speed shaft is set on the piston to achieve a stable damping effect. A variable speed shaft is set on the piston, and the cross-sectional area of ​​the variable speed channel is set to be inversely proportional to the pressure value. This makes the cross-sectional area of ​​the variable speed channel smaller when the pressure increases, making it more difficult for the viscous fluid to flow, and ultimately resulting in a better damping effect.

[0034] The working principle and usage process of this utility model are as follows: When constructing a basement structure, the user uses bolt assembly 4 to assemble and install the sealing assembly 3, lower fixing plate 5, and upper fixing plate 7 onto the gap of the basement structure's bottom plate 1. Then, the annular plate 22 in the protective warning device 2 is installed on the outside of the threaded ring 21 on the upper fixing plate 7 via threads. The damper 23 and elastic rubber cylinder 24 between the protective plate 25 and the annular plate 22 can buffer against people stepping on it, thereby reducing the possibility of structural deformation and damage to the upper fixing plate 7. The elastic rubber ring 27 can play an auxiliary sealing role. When there is an accidental water leak and it is about to seep into the structure, some water will pass through the mesh ring 264 in the warning assembly 26 and be absorbed by the color-changing silica gel desiccant 263 in the transparent box 261, thereby preventing water leakage. The color-changing silica gel desiccant 263 changes, allowing users to observe and perform maintenance promptly. When necessary, staff can unscrew the threaded cap 262 to replace the color-changing silica gel desiccant 263. During structure assembly, staff can connect the mounting plates 61 on the two fixed frames 64 to the lower fixed plate 5 using the two screws 62 in the auxiliary shielding device 6. Then, they can rotate the two screws 63, which are threadedly connected to the fixed frames 64 and bearing-connected to the moving blocks 65. The outer side of the moving blocks 65 fits against the inner side of the fixed frames 64, so the two screws 63 drive the two moving blocks 65 to move, thereby expanding the shielding range of the structure below the base plate 1 and better adapting to different basement structures or underground conditions.
