Description

Technical Field

[0001] The utility model relates to the technical field of sliding form construction, in particular to a disassembly-free steel pipe truss sliding form platform. Background Art

[0002] Slipform construction is a construction process for cast-in-place concrete engineering. Compared with conventional construction methods, this construction process has the advantages of fast construction speed, high degree of mechanization, saving materials and labor required for supporting formwork and erecting scaffolding, and being able to disassemble and flexibly assemble the formwork more conveniently and reuse it. This construction method is often used in reinforced concrete chimneys and circular structures. The lifting power of the slipform construction process generally adopts a hydraulic device, that is, a hydraulic jack. At present, many slipform projects use large-tonnage hydraulic jacks. The invention patent with the current patent publication number CN108952145A discloses a formwork frame that uses a slipform outer platform to support the cantilevered eaves gutter outside the silo. The present invention relates to the field of construction engineering technology; it comprises a rectangular steel truss slipform outer platform, angle steel and bolts; wherein the inner sides of the upper chord and the lower chord of the rectangular steel truss slipform outer platform are fixed with angle steel, and the other end of the angle steel is fixed to the slipform gantry column on one side of the slipform gantry by bolt connection. Its construction is simpler and safer, and can meet the height space of the eaves gutter bottom plate construction, while meeting the height requirements and safety guarantees of the warehouse wall slipform, and is more practical.

[0003] During the jacking process of the existing silo slipform platform, the hydraulic rod needs to be connected to the support rod of the silo. When the slipform platform is jacked up, the entire weight of the slipform platform will be concentrated on the connection between the hydraulic rod and the support rod. The fixing holes of the support rod are subjected to greater pressure, which will cause the support rod to deform, causing the slipform platform to tilt and reducing the safety of the slipform construction. To solve the above problems, the present application proposes a disassembly-free steel pipe truss slipform platform. Utility Model Content
