Title:
HOLLOW FORMWORK FOR USE IN CONSTRUCTION
Document Type and Number:
WIPO Patent Application WO/2022/073258
Kind Code:
A1
Abstract:
A hollow formwork for use in construction comprises an upper base (11) of the formwork and a peripheral side wall (12) connected to the upper base (11). The hollow formwork further comprises a perpendicularly extending edge (3) connected to the peripheral side wall (12). A through-hole (31) is provided on the perpendicularly extending edge (3). The perpendicularly extending edge (3) of the hollow formwork is used as a connecting edge to connect to a ribbed-beam template etc. A connecting hole provided on the perpendicularly extending edge prevents putty used in subsequent construction from corroding a connector, and improves construction precision and quality. The perpendicularly extending edge (3) of the hollow formwork has an increased thickness, allowing for various loads during construction. The hollow form can be quickly manufactured, and has low costs and good performance.
