Description

Изобретение относится к области прокатки.The invention relates to the field of rolling.

Известны двутавтррые балки, содержащие волнистую стенку и полки £1],Known I-beams containing a corrugated wall and shelves £ 1],

Недостаток известного профиля потеря устойчивости при изгибе, для предотвращения которой увеличивается толщина стенки и как следствие возрастает расход металла.The disadvantage of this profile is the loss of stability during bending, to prevent which the wall thickness increases and, as a result, the metal consumption increases.

Целью изобретения является повышение жесткости и устойчивости балок при уменьшении толщины стенок.The aim of the invention is to increase the rigidity and stability of beams while reducing wall thickness.

Поставленная цель достигается тем, что в двутавровом профиле, включающем волнистую стенку и полки, согласно изобретению, волны по стенке выполняют по ее высоте с радиусами кривизны порядка толщины стенки, причем наружный радиус каждой волны больше ее внутреннего.This goal is achieved by the fact that in the I-beam profile comprising a corrugated wall and shelves, according to the invention, the waves along the wall are performed along its height with radii of curvature of the order of the wall thickness, and the outer radius of each wave is greater than its internal.

На чертеже представлен общий вид балки, где 1 - стенка, 2, 3 - полки, R - наружный радиус, R<- внутренний радиус.The drawing shows a General view of the beam, where 1 is the wall, 2, 3 are the shelves, R is the outer radius, R <is the inner radius.

Расположение волн по высоте стенки позволяет при меньшей ее толщйне обеспечить необходимую жесткость конструкции и устойчивость балки.The location of the waves along the height of the wall makes it possible to provide the necessary rigidity and stability of the beam at a lower thickness.

Claims

This invention relates to the field of rolling. There are two-beam beams, a corrugated wall and shelves flj. A disadvantage of the known bending buckling profile, for the prevention of which the wall thickness increases and, as a consequence, the metal consumption increases. The aim of the invention is to increase the rigidity and stability of the beams while reducing the wall thickness. This goal is achieved by the fact that in an I-profile, including by the wavy wall and shelves according to the invention, waves along the wall are made along its height with radii of curvature of the order of the wall thickness, and the outer radius of each wave is greater than its internal. The drawing shows a general view of the beam, where 1 is a wall, 2, 3 are shelves, R is the outer radius, the inner radius. The arrangement of the waves along the wall height allows, with a smaller thickness, to provide the necessary rigidity of the structure and stability of the beam. DETAILED DESCRIPTION OF THE INVENTION A double-T profile with a wavy wall and a shelf, characterized in that, in order to increase the rigidity and stability of the beams while reducing the wall wall tag, the wave on the steak is filled along its height with curvature radii of the order of the wall thickness, and the outer radius of each wave is larger her inner.
