JPH10235497A - Backing by nonscallap process - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide the shape and structure of a backing by which nonscallap process is applicable according to the shape of the backing, the required space for this welding is secured between the beam flange and a web subjected to edge preparation, and mounting at one operation is easily available. SOLUTION: A backing 6 provided with the radius of fillet and opening according to the size of a wide-flange shape steel 5 is mounted with the flat bar. Mounting the backing 6 makes needles the scallap process which has been deemed necessary, and the one operation mounting makes shortening of work available.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a special shape and structure of a backing metal used for a beam end weld of a column / beam joint.

[0002]

2. Description of the Related Art In a conventional backing hardware, a scallop method is used for manufacturing a column / beam welding connection having a steel structure.

[0003]

The conventional metal backing requires a scalloping method in order to avoid the intersection of the meat welding lines, which leads to a decrease in the cross-section and the deformation performance. Now that the quality of steel and welding consumables has been significantly improved and welding techniques have been advanced, the necessity has become less clear.

An object of the present invention is to use a non-scallop construction method according to the shape of a backing metal, and further secure a space for main welding between a beam flange and a web that has been subjected to beveling, thereby facilitating one-touch operation. It is an object of the present invention to provide a shape and a structure of a backing hardware that can be attached to the backing.

[0005]

Means for Solving the Problems In order to achieve the above object, in the present invention, a radius is provided partially along a fillet of an H-shaped rope, and a space for main welding is secured. Leave a flat part without having a radius as much as necessary.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 2, a flat bar (1) is provided in the direction of the arrow to secure a main welded portion.

[0007]

Since the present invention is configured as described above, it has the following effects.

By mounting the backing hardware of the present invention, the work can be shortened by one-touch mounting without the need for the scalloping method which has been required up to now.
