Description

Technical Field

[0001] This utility model belongs to the field of building structure technology, and in particular relates to a sliding connection structure between a retaining wall and the main structure. Background Technology

[0002] As living standards improve, people's demands for quality of life are also constantly increasing, leading to the emergence of many "small but exquisite" commercial complexes. These complexes often feature landscaped green spaces, have steep site slopes, and typically include retaining walls for the above-ground portion of the main structure. This results in the overall structure having significantly greater stiffness on the side with the retaining wall than on the side without, severely impacting structural safety under earthquake conditions.

[0003] The current common handling method is as follows: Figure 1 As shown, the reinforced concrete retaining wall is rigidly connected to the main structure. When the main structure has a retaining wall on only one side, this connection method results in the overall structure having a much greater stiffness on the side with the retaining wall than on the side without the retaining wall. This makes it difficult to pass the structural calculation indicators and affects the structural safety.

[0004] To address this, a design was developed for a sliding connection between the retaining wall and the main structure, which can satisfy both the requirements for retaining soil and waterproofing the building, as well as the requirements for structural safety. Utility Model Content

[0005] The purpose of this utility model is to overcome the problems of the prior art by disclosing a sliding connection structure between the retaining wall and the main structure. Through the structural design of the sliding connection structure of this application, the situation in which the stiffness of the overall building structure on the side with the retaining wall is much greater than that on the side without the retaining wall is avoided.

[0006] The objective of this utility model is achieved through the following technical solution:

[0010] According to a preferred embodiment, when the gap between the retaining wall and the frame beam corresponding to the main structure is greater than a preset value, a cast-in-place concrete structure is provided at the corresponding gap position; the cast-in-place concrete structure is connected to the main structure and is connected to the polytetrafluoroethylene plate on the side.
