Description

Technical Field

[0001] This application relates to the technical field of building walls, and particularly to a sealing structure for the exterior wall of an existing sunken courtyard. Background Art

[0002] The design of the exterior wall of a sunken courtyard is an important part of the sunken courtyard concept. A sunken courtyard, also known as the "Garden Level", is a design technique where, in areas with a height difference in terrain, through artificial treatment of the height difference and landscaping, a part of the original basement space is transformed into an open space facing the garden. This design not only releases the auxiliary area functions of the traditional basement, such as equipment rooms and servants' quarters, but also adds functional areas such as family entertainment and outdoor activity and leisure to the basement, greatly improving the comfort and practicality of living.

[0003] When canceling the through-length sunken courtyard in an existing building, the conventional method is to implant steel bars around the door and window openings of the exterior wall of the basement and pour concrete at the door opening to achieve sealing.

[0004] The above method can achieve the sealing effect to a certain extent, but there are many problems and deficiencies. For example, the number of implanted steel bars is relatively large, which not only increases the construction difficulty but also may damage the original concrete wall, affecting the stability of the building structure. And the pouring construction difficulty is relatively high, and it is difficult to ensure the quality of concrete pouring. Utility Model Content

[0017] Optionally, the eaves include structural steel bars implanted in itself, the structural steel bars penetrate and are fixedly connected to the original wall, and the eaves are implanted into the original wall through the structural steel bars.

[0018] By adopting the above technical solution, by implanting the structural steel bars of the eaves into the original structure, the stability and safety of the eaves on the original wall and the retaining wall can be improved.

[0019] Optionally, a thermal insulation and waterproof board is fixedly connected to the outer wall of the retaining wall.

[0020] By adopting the above technical solution, by setting a thermal insulation and waterproof board on the outer wall of the retaining wall, the temperature transfer efficiency can be reduced, and the rainwater outside the retaining wall can be isolated, thereby further improving the thermal insulation performance and waterproof performance of the building.

[0021] Optionally, a protective board is fixedly connected to the side of the thermal insulation and waterproof board facing away from the retaining wall.

[0022] By adopting the above technical solution, the thermal insulation and waterproof board and the retaining wall can be protected by the protective board, thereby further improving the service life of the thermal insulation and waterproof board and the durability of the building.
