Description

  The present invention relates to a connecting structure of a vertical beam and a horizontal beam applied to a lattice door, a partition lattice door, a fence, a surface lattice, a gate, and the like.

  Conventionally, in lattice doors, partition lattice doors, fences, surface lattices, gates, etc., various structures have been proposed in which a vertical beam serving as a vertical member and a horizontal beam serving as a horizontal member are connected in a cross shape. .

  For example, in Patent Document 1 below, a notch recess that matches the cross-sectional shape of the horizontal beam is formed in the horizontal beam connecting portion of the vertical beam, and the longitudinal beam is used as the notch recess of the vertical beam. A connection structure of a vertical beam and a horizontal beam that are fitted in an intersecting manner is disclosed.
