Abstract
Description
Technical Field
[0001] This utility model relates to the field of building technology, and in particular to a waterproof structure for expansion joints at the junctions of building elevation differences. Background Technology
[0002] The Lingnan region has a humid and rainy climate, and residential buildings and public spaces often employ elevated and corridor-connected space design techniques to meet the architectural needs of the region. However, the intersection and connection between elevated corridors and buildings and the connecting passageways usually have different building elevations and require expansion joints, which are often "weak points" in the waterproofing structure.
[0003] Existing waterproofing measures for expansion joints have many shortcomings. For example, poor construction worker quality, complex construction processes, and the tendency of waterproofing materials to fail over time or due to natural wear and tear all contribute to frequent rainwater leakage problems. This is especially true in areas with frequent heavy rainfall, where waterproofing is particularly problematic. Relying solely on a waterproofing layer is insufficient to completely solve the waterproofing and drainage functions of expansion joints, causing inconvenience for building users. To address these issues, current construction techniques lack an effective, economical, and long-term solution that combines structural components with waterproofing methods at the junctions of building corridors with elevation differences. This solution would improve the waterproofing performance of these areas and effectively address problems and deficiencies caused by poor construction, weather conditions, aging, and human factors, thereby resolving rainwater leakage issues in areas with frequent heavy rainfall.

[0037] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0038] Example 1
[0039] Please refer to Figure 1 or Figure 2 A waterproof structure for an expansion joint at the junction of building height differences includes an expansion joint body, which is located at the junction between a first building and a second building, and includes a horizontal expansion joint 400 and a vertical expansion joint 300; in this embodiment, the first building can be an elevated corridor and the second building can be a high-rise building.
[0040] The first waterproof layer 500 is disposed within the transverse expansion joint 400;

The first structure 210, the second structure 220 and the third structure 230 are continuously and uninterruptedly arranged.
[0043] Through the above structural design, by setting a vertical support 120 and a horizontal shielding part 110 on one of the building structures, with the horizontal shielding part 110 located on top of the vertical support 120 and extending towards the other building structure, a height difference is created, effectively achieving the rainproof function of the top. The first waterproof layer 500 is the first object to block rainwater from entering; it is set within the horizontal expansion joint 400, filling the gaps in the horizontal cavity. The second waterproof layer 600 is set within the vertical expansion joint 300, filling the gaps in the vertical expansion joint 300, which is beneficial for further waterproofing. This effectively enhances the waterproofing performance at the junction of the elevated corridor and the building height difference, physically preventing rainwater from entering the expansion joint. byWhile accommodating deformation at the junction of the elevated walkway and the building's height difference, it not only prevents rainwater leakage but also effectively addresses the issue of water loss in the waterproofing materials caused by construction, weather, or aging, thus ensuring the waterproofing safety of this area in frequent rainy weather. The first structure 210 wraps around the entire first waterproof layer 500, further preventing rainwater infiltration. The second structure 220 extends upward from the first waterproof layer 500 along the transverse expansion joint 400, and the third structure 230 extends downward from the first waterproof layer 500 along the transverse expansion joint 400, which helps prevent rainwater penetration.

A vertical expansion joint 300 is formed between the vertical support part 120 and the outer surface of the building construction layer 800.
[0045] Through the above structural design, a vertical support 120 and a horizontal shield 110 are provided on the first building. The horizontal shield 110 is located on the top of the vertical support 120 and extends towards the building structure layer 800 to form a height difference, effectively realizing the rain protection function of the top.
[0046] Specifically, the second structure 220 of the first waterproof layer 200 is disposed on the inner side of the transverse blocking portion 110 of the structural layer 100 and extends to the outer side and upper surface of the transverse blocking portion 110; the third structure 230 of the first waterproof layer 200 is disposed on the top surface of the building structure layer 800 and extends to the inner side and upper surface.
[0047] Specifically, the outer side and upper surface of the transverse shielding portion 110 of the structural layer 100 are provided with at least one second waterproof layer 130, and the inner side and upper surface of the building structure layer 800 are provided with at least one third waterproof layer 140.
[0048] The second waterproof layer 130 and the third waterproof layer 140 are used to further enhance the waterproof function.
[0049] Specifically, the lateral shielding portion 110 and the vertical support portion 120 of the structural layer 100 are integrally formed.
[0050] Through the above structural design, the materials used to manufacture the lateral shielding part 110 and the vertical support part 120 can be cement.
[0051] Specifically, the first waterproof layer 500 is a polyethylene foam rod.
[0052] Through the above structural design, the polyethylene foam rod has an extremely low water absorption rate, almost no water absorption, and can effectively block rainwater from entering.
[0053] Specifically, a sealant 700 is provided at the connection between the first waterproof layer 500 and the transverse expansion joint 400.
[0054] Through the above structural design, the sealant 700 is an elastic paste-like building sealant material used to fill building joints, which has waterproof and airtight functions and can effectively increase the sealing performance.
[0055] Example 2
[0056] The waterproof structure of the building elevation difference junction expansion joint provided in Example 1 is further optimized, specifically, as follows: Figure 1 or Figure 2 As shown, the second waterproof layer 600 abuts against the two horizontal surfaces of the vertical expansion joint 300.
[0057] The above structural design achieves a good sealing effect.
[0058] Example 3
[0059] The waterproofing structure of the expansion joint at the junction of building elevation differences provided in Embodiment 1 or 2 is further optimized, such as... Figure 1 or Figure 2 As shown, the second waterproof layer 600 is a polystyrene foam board.
[0060] Through the above structural design, polystyrene foam boards have a closed-cell structure, low water absorption, and excellent water resistance, which can further effectively prevent rainwater from entering.
[0061] Specifically, a brick base 900 is provided on the top surface of the horizontal shielding part 110.
[0062] The above structural design allows for easy passage of people at the 900mm brick base, and the design can be adjusted according to actual conditions.
[0063] The application process of the waterproof structure for the building elevation difference junction expansion joint provided by this utility model is as follows:
[0064] By installing vertical support parts 120 and horizontal shielding parts 110 on the building structure, and installing a first waterproof layer 500 and a second waterproof layer 600 in the horizontal expansion joint 400 and the vertical expansion joint 300 respectively, the waterproof performance at the junction of the elevated corridor and the building height difference can be effectively enhanced. This physically prevents rainwater from entering the expansion joint, so that while meeting the deformation requirements at the junction of the elevated corridor and the building height difference, it not only prevents rainwater leakage, but also effectively addresses the problem of water loss of each layer of waterproof material caused by construction, weather or aging, thereby ensuring the waterproof safety of this part in the context of frequent rainstorms.
