Vous êtes-vous déjà demandé comment les gratte-ciel se tiennent debout et solides ? Cet article explore les merveilles des poutres en H standard américaines, en mettant l'accent sur leur conception, leurs types et leurs applications. Vous apprendrez comment ces géants d'acier contribuent à la construction moderne grâce à leur solidité et à leur efficacité. Rejoignez-nous pour découvrir les secrets de ces merveilles d'ingénierie !
La poutre en H standard américaine est conforme à la norme ASTM, avec trois qualités principales : A36, A572 et A992.
Par exemple, les matériaux A36 et A572 sont des aciers de construction au carbone, tandis que le matériau A992 est un acier faiblement allié.
La poutre H standard américaine est un profilé haute performance avec une surface de section optimisée et un rapport résistance/poids plus raisonnable, nommé d'après sa section transversale en forme de H.
En raison de sa disposition à angle droit dans toutes ses parties, la Poutre en H Il présente une forte résistance à la flexion, une construction simple, un bon rapport coût-efficacité et une structure légère, ce qui le rend largement applicable.
Le processus consiste à libérer l'acier en fusion lorsque sa température et sa composition répondent aux spécifications du type d'acier à affiner. Lors du soutirage de l'acier, il faut veiller à ce que le laitier ne pénètre pas dans la poche de coulée.
Les additifs utilisés pour ajuster la température, la composition et la désoxydation de l'acier en fusion sont ajoutés à la poche ou au flux d'acier pendant le taraudage, également connu sous le nom d'alliage de désoxydation.
1) Soulager les stress interne de la matière
2) Ajuster la dureté du matériau (généralement pour l'augmenter) avec une légère réduction de la plasticité.
Il s'agit d'une préparation en vue d'un traitement ultérieur. Il a un effet similaire à celui de recuitmais vise à améliorer l'efficacité et à réduire les coûts.
