FORMWORK
Document Type and Number:
WIPO Patent Application WO/2018/061075
Kind Code:
A1
Abstract:
Provided is formwork that does not require a screw hole to be formed in a concrete column and has excellent mounting workability on site. A formwork 1 comprises an upper member 11 and a lower member 12 that are fixed to each other by a bolt-and-nut 5. The upper member 11 is provided with hook parts 111 that each engage with a bottom-side flange 21a of an adjacent steel H-beam 21. The lower member 12 covers a gap 4 that is formed between a lower end of a steel beam 2 having a precast concrete part 2b and an upper end of a reinforced concrete column 3 at the site where the steel H-beams 21 intersect. Because the formwork 1 comprises the hook parts 111, a screw hole does not need to be formed in a reinforced concrete column 3 and mounting workability on site is excellent.
