WONG WAI HONG

The present invention provides a hollow floorslab formwork, a hollow floorslab structure and a construction method of hollow floorslab. The hollow floorslab structure is formed by splicing together a plurality of hollow floorslab formworks, and the hollow floorslab formworks each comprise a flat plate portion (1). A lower portion of the flat plate portion is provided with a plurality of supporting legs (4), and an outer edge of the flat plate portion is provided with a frame (2) comprising a plurality of protective plates (21, 22, 23,24). The protective plates are each provided with a reversely-fastened plate (31, 32), and adjacent hollow floorslab formworks are spliced together by fastening the reversely-fastened plates on the protective plates. The construction method comprises the following steps: a first hollow floorslab formwork is laid first; other periphery on a former hollow floorslab formwork, except the periphery provided with a reversely-fastened plate, is spliced with a latter hollow floorslab formwork, and the reversely-fastened plate of the latter hollow floorslab formwork is fastened on the protective plate of the former hollow floorslab formwork.
