Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method for connecting a grid body, such as a fence, a gate, etc., in which a plurality of vertical grids are arranged on a horizontal frame.

(Prior Art) Conventionally, when fixing the horizontal and vertical lattices in this type of lattice body, it has generally been done by welding or screwing the mounting walls of the vertical lattice and the mounting surface of the rim. In the case of welding, skill is required, and in the case of screw fastening, the number of parts increases, so both of them have the drawbacks of high costs and poor workability.

Recently, a method has been proposed in which a cut-and-raised piece is provided on the vertical beam, and the cut-and-raised piece is inserted into a groove provided in the mounting portion of the horizontal beam and then bent to fix the piece. This method has the disadvantage that the processing is extremely complex and requires high accuracy in preprocessing.

(Objective of the Invention) The present invention has been made in view of the above points, and has a good appearance without exposing machining marks etc. to the outside, and also makes it possible to easily assemble horizontal and vertical lattices. The purpose of this study is to propose a method for combining lattice bodies.

(Means for Achieving the Object) A method for joining a lattice body according to the present invention provides a lattice body in which a plurality of vertical lattices are arranged in front of upper and lower horizontal beams, the vertical lattice having a square pipe shape, The upper and lower horizontal beams have a structure that includes a mounting side member and a closing member that can be fitted into each other, and the mounting wall of the vertical lattice and the mounting portion of the mounting side member are cut and raised with a jig with the mounting part of the mounting side member brought into close contact with each other. Along with pressing the pieces,
The cut-and-raised pieces of the mounting portion of the mounting-side member embrace the cut-and-raised pieces of the mounting wall of the vertical lattice, and are joined together by bending the arms while coming into close contact with each other, and are further closed to the engagement convex portion of the mounting-side member. It is characterized in that the engaging recesses of the members are fitted.
