Description

Technical Field

[0001] This utility model relates to the technical field of building waterproofing structures, and in particular to a waterproofing structure for building foundation slabs. Background Technology

[0002] Current corridor construction methods include cantilevered corridors and recessed corridors. A cantilevered corridor refers to a horizontal traffic space that extends beyond the building's exterior wall; while a recessed corridor, borrowing the concept of a recessed balcony, is a horizontal traffic space recessed into the building's exterior wall. Currently, high-rise residential buildings commonly use cantilevered corridors. Although they are more expensive, they offer more reasonable unit layouts, ensuring cross-ventilation in middle units, which is beneficial for product segmentation and pricing.

[0003] In recent years, most high-rise residential building corridors have been designed to be open-plan. This is partly because an open design facilitates ventilation for middle units; and partly because enclosed corridors require fire-fighting smoke extraction systems and additional smoke extraction shafts, increasing the shared area, construction costs, and overall expenses. A cantilevered corridor can be considered an unenclosed balcony, lacking any protective structure except for railings or balustrades.

[0004] Currently, the top surface of the retaining wall of many high-rise residential corridors is too low compared to the finished floor surface, creating a stepping surface that poses a serious safety hazard. Furthermore, during heavy rain or storms, water leaking into the corridors cannot be effectively drained, leading to extensive flooding of the corridor floor, which can easily cause damage and affect usability.

[0005] Currently, no effective solution has been proposed to address the problems of water accumulation and large-scale flooding of connecting corridors in related technologies. Utility Model Content

[0144] The method of using this utility model is as follows:

[0146] Placement element 21 is placed in cavity element 13 and fixed to transverse main body element 11 by bolts;

[0147] During the process, the first conveying element 41 is inserted into the drainage element 14 so that the first conveying element 41 and the drainage element 14 are connected;

[0148] Place the cover element 51 in the cavity element 13 and engage the second snap-fit ​​element 53 with the first snap-fit ​​element 23.

[0152] (III) Cleanup Operation

[0153] The cover plate element 51 is lifted and moved laterally by the third through slot element 54, which causes the second snap-fit ​​element 53 to move upward and in the length direction along the height direction of the first snap-fit ​​element 23 until the second snap-fit ​​element 53 is disengaged from the first snap-fit ​​element 23, so as to separate the cover plate element 51 from the placement element 21.

[0154] Finally, the open end of the placement element 21 is exposed to clean the first drainage element 32.

[0155] The advantages of this invention are that it utilizes a placement unit to provide a stable placement space for the diversion and conveying units, fixing them within the corridor structure and preventing displacement or damage to the drainage facilities due to external impacts or vibrations. This ensures long-term stable operation of the drainage facilities, guaranteeing the continuous drainage function of the corridor, even in inclement weather or during periods of high pedestrian traffic. The coordinated use of the diversion and conveying units transports the diverted water to the drainage channel, ensuring timely drainage of accumulated water and resolving the problem of ineffective water removal, thus guaranteeing the normal use of the corridor and preventing water accumulation from affecting pedestrian safety. The cover plate unit seals the top of the placement unit, protecting the diversion and conveying units placed within. It also prevents debris from entering the drainage system, preventing leaves, garbage, and other contaminants from clogging the drainage pipes and ensuring smooth drainage. The obstruction of debris reduces wear and corrosion inside the drainage facilities, extending the service life of the conveying and diversion units and reducing maintenance costs and frequency.
