Abstract
Description
Technical Field
[0001] The utility model relates to the field of building structures, in particular to a deformation joint waterproof structure. Background Art
[0002] Buildings often deform under the influence of external factors, leading to cracks or even damage. In addition, deformation joints are reserved in buildings because of reasons such as excessive length or the inability of the connecting passages between two buildings to effectively coordinate the deformation on both sides. When the deformation joint is in contact with the covering soil or water source, a certain waterproof structure needs to be adopted for the deformation joint for waterproofing requirements. In the existing deformation joint waterproofing construction method, since the rubber water stop and the anchor bars on both sides of the seam occupy a certain space, this waterproofing structure can be applied to wall panel-type connecting passages, beams or column wall side cantilevers and other parts. However, when the beam or column wall side cannot be cantilevered and the beams and columns and walls are separated by only the width of the deformation joint, the waterproofing structure will cut off the stirrups in the beam and the vertical longitudinal bars in the column wall, and this waterproofing structure affects the structural force. And when there is a height difference between the building objects on both sides of the deformation joint, the existing deformation joint waterproofing structure cannot meet the waterproofing requirements. Utility Model Content

[0011] Furthermore, the first building body and the second building body are beam, column and wall structures.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.
[0022] like Figure 1As shown, the utility model discloses a deformation joint waterproof structure, including a first building body 11 and a second building body 21, and a first deformation joint 12 located between the first building body 11 and the second building body 21, a first extension body 13 is arranged along the water-facing surface of the first building body 11, a second extension body 23 is arranged along the water-facing surface of the second building body 21, a second deformation joint 22 is reserved between the first extension body 13 and the second extension body 23, a first sealing component is arranged in the first deformation joint 12, a second sealing component is arranged in the second deformation joint, and a third sealing component covers the first extension body 13, the second extension body 23 and the water-facing surface of the second deformation joint 22, and extends to the first building body 11 and the second building body 21. The deformation joint waterproof structure of the utility model does not need to expand the spacing of the original building, effectively increases the use space inside the deformation joint, and reduces the impact on the original building function; the extension waterproof structure forms a natural height difference with the buildings on both sides, and the water flow will be preferentially discharged to the floor slabs on both sides, effectively reducing the service time of the waterproof structure, thereby improving the life and durability of the waterproof structure.
[0023] Specifically, the first sealing component includes a flexible waterproof sealant 36, which fills the first deformation joint 12. The second sealing component is located inside the second deformation joint 22, including a rubber water stop 33 located in the middle of the second deformation joint 22, a first sealant 31 located at one end of the second deformation joint 22 and a second sealant 35 located at the other end, and a first polystyrene strip 32 located between the first sealant 35 and the rubber water stop 33, and a second polystyrene strip 34 located between the second sealant 35 and the rubber water stop 33. The rubber water stop 33 penetrates and extends into the first extension body 13 and the second extension body 23 on both sides along the cross section of the second deformation joint 22. The third sealing component includes a waterproof roll reinforcement layer 41, a top plate waterproof layer 42, a foam plastic rod 43 and a protective layer 44 from the inside to the outside of the first extension body 13, the second extension body 23 and the second deformation joint 22. The waterproof coiled material reinforcement layer 41 covers the water-facing surface of the first extension body 13, the second extension body 23 and the second deformation joint 22, the top plate waterproof layer 42 and the protective layer 44 cover the water-facing surface of the first extension body 13, the second extension body 23 and the second deformation joint 22 and extend to the first building body 11 and the second building body 21, and the waterproof coiled material reinforcement layer 41 and the top plate waterproof layer 42 reserve a position for setting the foam plastic rod 43 outside the second deformation joint 22. By filling the first and second sealing components inside the deformation joint, and covering the third sealing component outside the deformation joint and extending to the building body, the water seepage path is effectively extended, and the waterproof effect is better.
[0024] Furthermore, the first extension body 13 is provided with a first stress-bearing reinforcement 14 extending from the first building body 11 to the first extension body 13, and the second extension body 23 is provided with a second stress-bearing reinforcement 24 extending from the second building body 21 to the second extension body 23, and the rubber water stop 33 avoids the first stress-bearing reinforcement 14 and the second stress-bearing reinforcement 24. The stress-bearing reinforcement and the rubber water stop are provided in the extension body to achieve waterproofing, and the rubber water stop avoids the stress-bearing reinforcement in the extension body, and the original main structural components do not need to be modified or avoided, which greatly simplifies the design; for projects with a tight construction period, stress-bearing reinforcement can be reserved during the construction of the building body, and the subsequent secondary construction can greatly speed up the construction progress.
[0025] Combination Figures 1 to 3 As shown, the first building body 11 and the second building body 21 are beam, column and wall structures. When the utility model is applied to the basement column side, the distance between the two columns is effectively reduced, which can effectively reduce the construction space of the basement or reduce the impact on the column side parking space. In one embodiment, Figure 2 As shown, the beam, column and wall structures on either side of the first building body 11 and the second building body 21 include a cantilever plate 51. The remaining waterproof sealing structures are the same.
[0026] like Figure 3 As shown, in another embodiment, there is a height difference between the water-facing surfaces of the first building body 11 and the second building body 21, the first extension body 13 extends along a first direction, and the second extension body 23 extends along a second direction, forming a second horizontal deformation joint 22. The rest of the waterproof sealing structures are the same.
[0027] During construction, the first building body 11 and the second building body 21 are constructed first, and the first force-bearing reinforcement 14 and the second force-bearing reinforcement 24 are reserved to speed up the construction progress. After the first building body 11 and the second building body 21 reach a certain strength, the flexible waterproof sealant 36 can be constructed; then the second sealant 35, the second polystyrene strip 34, the rubber waterstop 33, the first polystyrene strip 32, and the first sealant 31 are installed and constructed, and then the first epitaxial body 13 and the second epitaxial body 23 are cast; after the first epitaxial body 13 and the second epitaxial body 23 reach a certain strength, finally the waterproof membrane reinforcement layer 41, the top plate waterproof layer 42, the foam plastic rod 43 and the protective layer 44 are constructed.
[0028] In summary, the expansion joint waterproof structure of the utility model has mature technology, convenient materials, relatively low cost, and is easy to promote.
