A TYPE OF SHEET STEEL JOINTING METHOD
Document Type and Number:
Japanese Patent JP2001220861
Kind Code:
A
Abstract:
To provide a type of method for jointing two sheets of steel such as galvanized sheet steel more firmly thereby increasing the strength, improving the conventional joints by bending the interlocking portions of each sheet twice thereby eliminating the defects of the conventional roof sheet steel such as peeling-off of joint portions and the galvanized sheet steel from the roof sheathing when strong wind blows.
In this method, two sheets of steel to be jointed are bent twice to the inner side at the jointing position. In this way, the strength of the jointing portion increases and the two sheets of steel can be jointed easily.
