Technical Field

[0001] The utility model relates to the technical field of foundation, in particular to a foundation structure. Background Art

[0002] In construction projects, the foundation is the basis of the building, and the stability and safety of its structure are crucial to the safety of the entire building. With the development of construction technology and the continuous emergence of high-rise buildings, the requirements for the strength, stability and durability of the foundation structure are becoming higher and higher. Therefore, a foundation structure that is fast, stable and easy to construct is needed.

The bottom of the reinforced steel frame arranged in the concrete wall is fixedly connected to the steel base arranged in the base layer, so that the structure is firm and stable. However, when pouring concrete, the foundation structure requires a support formwork to limit the concrete. After the concrete solidifies, the support formwork needs to be removed. The process of installing and removing the support formwork is relatively cumbersome. Utility Model Content
