Technical Field
The invention relates to the field of building construction, in particular to a steel pipe truss supporting system on the top of a silo and a supporting method thereof.
Background
Silos are generally tall and cylindrical in shape. In the prior art, when silo top construction is required, the silo top construction is usually carried out in a mode of arranging a floor scaffold. However, this construction method has problems that a large amount of materials such as steel pipes are consumed and that installation is time-consuming and labor-consuming.
Disclosure of Invention
The invention aims to provide a steel pipe truss supporting system for a silo roof and a supporting method thereof, and aims to solve the problems that the construction mode of the existing silo roof construction consumes more materials such as steel pipes and the like, and the erection consumes time and labor.

a steel pipe truss supporting system for the top of a silo comprises a steel pipe truss, a flower basket frame, a supporting rod, a threaded pull rod and a circle of climbing rods reserved on the upper portion of the silo;
the steel pipe truss is a spatial double-layer truss structure formed by steel pipes, and the flower basket frame is a steel pipe frame structure connected to the middle position of the lower end of the steel pipe truss;
the steel pipe truss is positioned on the inner side of the top of the silo, and the upper chord member and the lower chord member of the steel pipe truss are respectively and fixedly connected to an upper embedded part which is pre-embedded in the inner side wall of the top of the silo; the lower end of the supporting rod is fixed to a lower embedded part which is embedded in the inner side wall of the silo and is positioned below the upper embedded part, the supporting rod obliquely extends upwards to a lower chord member supported on the steel pipe truss, and the supporting point is positioned between the periphery of the steel pipe truss and the periphery of the flower basket;
the upper end of the threaded pull rod is connected with the climbing rod and is obliquely and downwards connected to the periphery of the lower end of the flower basket frame; the support rods and the threaded pull rods are crossed into an X-shaped position relation, and the steel pipe truss and the flower basket frame are combined into a whole and fixed in a silo in an upward-pulling and downward-supporting mode.
Through the silo top steel pipe truss support system of the silo top plate in the scheme, the construction of a floor type steel pipe scaffold can be omitted, and the construction template can be directly laid on the steel pipe truss. And the structure has extremely high stability and ensures the construction safety by arranging the space steel pipe truss and the flower basket frame below the space steel pipe truss and fixing the space steel pipe truss and the flower basket frame in the silo in an X-shaped pull-up and pull-down manner through the supporting rod and the threaded pull rod.
