Description

Technical Field

[0001] The utility model belongs to the technical field of suspended formwork structures, in particular to a butterfly-shaped double-helix suspended formwork structure for a post-cast zone of a basement top plate. Background Art

[0002] The post-cast joint of the basement roof is a zone that temporarily divides the basement roof structure into several parts. After the internal shrinkage or settlement of the components, the concrete of the construction joint is poured after a certain period of time to connect the structure into a whole. Construction must be strictly in accordance with the drawings. During construction, plugging plates should be used. Natural slopes should not be left to avoid making the concrete less dense and failing to reach the design strength grade. The steel bars in the beams and slabs in the post-cast joint should not be cut. The reinforcement bars in the beams and slabs in this area should be set strictly according to the design drawings.

[0003] The post-cast strip suspended formwork construction utilizes screws to pull the upper and lower load-bearing steel pipes of the post-cast strip against each other, transmitting force to the top slab concrete. This supports the bottom formwork to withstand the post-cast strip concrete and construction loads. The number of screws is determined based on the thickness of the basement top slab and the spacing of the screws along the length of the post-cast strip. Through design calculations, the cast-in-place reinforced concrete floor slab and beam formwork support columns within the span of the post-cast strip are arranged within a spacing of ≤2m. Once the concrete strength reaches 50% or more of the design value, the upper spiral of the butterfly-shaped double-helix jacking support is adjusted to lower the main back rib bracket, allowing the early removal of the fiberglass reinforced plastic formwork and the primary and secondary back ribs. The post-removal slab and columns (support plates) are retained to support the cantilevered components on both sides of the post-cast strip. In actual use, the bracket is supported by a metal plate connected to the steel pipe. However, due to different construction processes and different spacing between the steel pipes, the bracket cannot be used, requiring the replacement of steel plates of different sizes, which in turn affects support efficiency.
