Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a supporting formwork system suitable for the outer wall of a basement in a narrow space. Background Art

[0002] In construction projects, especially when constructing basement exterior walls in narrow spaces, traditional support formwork systems often have problems such as difficult installation, limited operating space, and unstable support effects. The narrow space restricts the operation of construction workers, making it difficult to fix and support the formwork, which in turn affects the construction quality and progress. Therefore, how to design a support formwork system suitable for basement exterior walls in narrow spaces has become a technical problem that needs to be solved urgently.

[0003] For example, a Chinese patent (CN110761189B) discloses a formwork support system for building concrete structures in narrow spaces, including a construction process, which includes cleaning the top surface of the pedestal, measuring and setting out, erecting a support, manufacturing and transporting steel bars, binding steel bars for the pier body, formwork processing and debugging, installing embedded parts, installing pier body formwork, mixing and transporting concrete, pouring pier body concrete, making concrete specimens, curing concrete, and removing formwork. The multi-blade stirring of the invention improves the mixing degree of concrete and the quality of concrete production. The reasonable construction method improves the construction safety factor and facilitates effective concrete building formwork support in narrow spaces.

[0004] The above scheme also has the following technical defects: the above scheme is not convenient for disassembling the supporting frame and the formwork, and the supporting frame is not convenient for folding. Due to the narrow construction space, it is difficult to carry the supporting frame and the formwork into the construction space at the same time. The formwork and the supporting frame need to be disassembled and moved into the construction space. At the same time, the above supporting frame is not convenient for folding and storage. Based on this, a supporting formwork system suitable for the exterior wall of a basement in a narrow space is proposed. Utility Model Content
