Изобретение относитс к элементам строительных конструкций, нредназначенных дл работы на изгиб, -и может найти нримененне, нашример, в качестне ригелей междуэтажных перекрытий, стронильных балок, прогонов и других элементов .конструкций.The invention relates to elements of building structures designed to work in bending, and can be found, for example, as quality girders for interfloor overlappings, stronel beams, girders, and other elements of the structure.
Известны балки с перфорированной стенкой, однако при увеличении высоты стенки приходитс увеличивать ее толщину, что -приводит к йерациональному распределению материала но сечению и, следовательно, к его излишнему расходу.Beams with perforated walls are known, however, as the height of the wall increases, it is necessary to increase its thickness, which leads to an irational distribution of the material over the cross section and, consequently, to its excessive consumption.
Цель изобретени - уменьшить все балки.The purpose of the invention is to reduce all beams.
Это достигаетс тем, что балка выполнена составной по высоте с отдельными жестко соединенными между собой част ми, одна из которых , меньшего ноперечного сечени , выпол«ена из материала большей прочности, чем прочность материала другой части балки.This is achieved by the fact that the beam is made of composite height with separate rigidly interconnected parts, one of which, of smaller cross section, is made of a material of greater strength than the strength of the material of the other part of the beam.
Кроме того, отношение высоты одной части стенки балки к высоте стенки меньшего поперечного сечени 0,5-1.In addition, the ratio of the height of one part of the beam wall to the height of the wall of a smaller cross section is 0.5-1.
На фиг. 1 изображена предлагаема балка с пврфорированйой стенкой, фасад; на фиг. 2 - то же, поперечное сечение по Л-А на фиг. 1.FIG. 1 shows the proposed beam with a pre-wall wall, facade; in fig. 2 is the same, the cross section along A-A in FIG. one.
Балка выполнена составной из двух частейThe beam is made of two parts
1 и 2, жестко соединенвых между сабой сваркой 3.1 and 2, rigidly connected between welding 3.
Часть 2 балки, меньшего поперечного сечени , и примыкающий к ией по с 4 выполнены из материала большей прочности, например из низколегированной стали марки 1412, а часть / балки, большего поперечного сечени , и примыкающий к ней по с 5 выполнены из менее прочного материала, например из малоуглеродистой стали марки Ст 3.Part 2 of the beam with a smaller cross section and adjacent to it in c 4 is made of a material of greater strength, for example, low alloy steel 1412, and part / beams with a larger cross section and adjacent to it in c 5 are made of a less durable material for example, of mild steel grade St 3.
Отношение высоты части / стенки балки с большим попфечным сечение.м к части 2 степки с меньшим поперечным сечением 0,5 - 1.The ratio of the height of the part / wall of the beam with a large popsch. Section m to part 2 steep with a smaller cross-section of 0.5 - 1.
