Technical Field
The utility model relates to a special landing leg structure of creeping formwork force bearing support especially relates to the creeping formwork system of curved surface wall concrete pouring construction field.
Background
The creeping formwork system is an important formwork system for vertical concrete structure construction, and has been widely used in various vertical concrete structure constructions of hydropower stations, bridge towers, high-rise buildings and the like due to the advantages of large bearing capacity, high construction speed, simple and convenient construction operation, good formwork integrity, good concrete forming quality and the like. The system finally transmits various loads to the surface of a poured concrete structure through the anchoring points of the creeping formwork supports and the supporting legs, and plays a key role in construction safety, construction efficiency and project progress control. However, when the creeping formwork system is applied to the construction of curved surface wall structures such as tail water piers, gate piers and the like of hydropower stations, industrial curved surface silos and the like, because the supporting leg bearing plate of the creeping formwork bearing support is of a flat plate structure and cannot be tightly attached to the curved surface concrete structure surface, in order to ensure that the load can be reliably transmitted to the concrete structure surface through the supporting leg of the bearing support, the construction site can only adopt various wedge blocks to fill the gap between the flat plate bearing plate and the curved surface wall to solve the problem. This temporary solution presents the following problems: 1. manufacturing wedges with different sizes according to curved walls with different sizes on site; 2. the customized wedge block basically belongs to a wear-out part and cannot be used in circulation in the construction of curved wall concrete with different sizes. 3. If certain construction errors are generated in the field construction process, the customized wedge block and the surface of the formed concrete curved wall still have the problem that the customized wedge block and the surface of the formed concrete curved wall cannot be attached tightly.
