Title
(EN) METHOD OF JOINING STEEL PRODUCTS, METHOD OF PROCESSING JUNCTION SURFACES OF STEEL PRODUCTS, AND REINFORCING MEMBER
(FR) PROCEDES DE JONCTION DE PIECES D'ACIER ET DE TRAITEMENT DES SURFACES DE JONCTION DE PIECES D'ACIER, ET PIECES DE RENFORT
Abstract
(EN)
It is arranged that a steel structure can be strongly assembled. In order to join two steel products, which form a steel structure or reinforcing members therefor, the junction surfaces of one and/or the other steel product are formed with a slip suppression-processed surface having one or a plurality of crests and grooves in a concentric circle, and the two steel products are clamped by means of connecting members extending through connecting holes in such a manner that the first and second slip suppression-processed surfaces are engaged with each other or are not engaged with each other, whereby the joining proof stress between the junction surfaces is increased.
(FR)
La présente invention concerne un procédé d'assemblage solide pour une structure d'acier. Le procédé concerne plus particulièrement la jonction de pièces d'acier constitutives d'une structure d'acier ou de pièces de renfort destinées à une telle structure. A cet effet, on forme sur les surfaces de jonction de l'une et/ou de l'autre pièce d'acier une surface dépolie portant au moins une crête et une rainure en cercle concentrique. On prend ensuite les deux pièces d'acier que l'on serre l'une contre l'autre au moyen de pièces de liaison passant par des trous de liaison de façon que les deux surfaces dépolies se touchent ou ne se touchent pas. Cela permet d'augmenter la contrainte de résistance à la jonction entre les surfaces de jonction.
