A Structure for Preventing Roughness and Fall-off between Concrete Slab Form Panels with Celling Finish

摘要

PURPOSE: An apparatus is provided to realize the smoothness of the ceiling face by removing the step between panels and to prevent the displacement or lowering of panels in the construction of a concrete slab mold used as a ceiling finishing material. CONSTITUTION: A crosswise groove(3) of 2-10mm of width is installed in the middle of an edge bar of a panel. An I-shaped iron(4) lower(5) is inserted to the crosswise grooves abutting between the panels to avoid vertical displacement of the panels in a facing portion. An upper(6) of the iron is buried in concrete to be grouted. Thereby, a concrete slab mold is fixed for long time.
