Description

Technical Field

[0001] The invention relates to the technical field of formwork support, in particular to a device for removing a pair of intermediate standard sections. Background Art

[0002] Shallow silo refers to a cylindrical above-ground granary with a ratio of silo wall height to inner diameter less than 1.5. It has the advantages of small footprint, reasonable structural force, strong seismic resistance, and good sealing performance. In terms of basic structure, shallow silo is usually composed of silo bottom, silo wall, silo roof, etc. The silo bottom usually adopts reinforced concrete strip foundation; the silo wall adopts reinforced concrete structure; reinforced concrete spherical shell or cone shell structure is more common in the silo roof structure. Among them, the silo wall construction is generally carried out with sliding formwork technology, and the silo roof is mostly constructed with silo roof support system. The silo roof support system consists of truss operation platform system and central column support. The truss operation platform system is a key place for construction personnel to carry out various operations and material stacking, and it is also an important support for pouring cone shell structure concrete. It is like a fully functional "air base", providing a stable and reliable working environment for construction. On this platform, construction personnel can carry out various construction operations such as steel bar binding, formwork adjustment, concrete pouring, etc. in an orderly manner to ensure the smooth progress of the construction process. Moreover, the reasonable design and layout of the truss operating platform system fully considers the operating convenience and safety of construction workers, greatly improves the work efficiency of construction workers, and reduces construction delays and accident risks caused by inconvenient operation or safety hazards.

[0003] However, the dismantling of the silo roof support system faces great challenges. In the traditional dismantling process of the silo roof support system, the truss operating platform system is usually dismantled in pieces first, and then the central column support is gradually dismantled from high altitude.
