Claims

[Scope of claims for utility model registration] (1) The frame is formed of a light metal frame material,
This is a light metal surface lattice in which crosspieces are assembled in a lattice shape within the opening surface of the frame, one of the crosspieces being a long crosspiece that continues in the longitudinal direction, and the other crosspiece being the long crosspiece. The short bar is divided at the joining part with the long bar, and one surface of the long bar has a continuous fin protruding in the longitudinal direction, and the end of the short bar is in contact with the fin of the long bar. A core material insertion part is formed in the short part and intersects the long part, and is continuous in the longitudinal direction. A light metal surface lattice with bars tied to a frame body or long bars. (2) Claim (1) in which the long and short bars are hollow pipes.
Light metal surface grating as described in . (3) The light metal surface lattice according to claim (1), wherein either the long bars or the short bars are plate-shaped. (4) The light metal surface grid according to claim (1), wherein the core material is a bolt, and the core material is screwed into a female thread formed in the core material insertion portion.
