Description
Изобретение относитс к области строительства и может быть использовано при разработке конструкций ферм с по сом из гнутых пустотелых профилей.The invention relates to the field of construction and can be used in the development of structures for trusses with catfish of bent hollow profiles.
Известна ферма из гнутых замкнутых профилей, включающа верхний и нижний по са с продольными выступами на их стенках, расоложенными симметрично относитель но центральных осей, и раскосную решетку.The known truss is of bent closed profiles, including the upper and lower sa with longitudinal protrusions on their walls, symmetrically disposed relative to the central axes, and a diagonal lattice.
Известна ферма обладает тем недостатком, что нерационально осуществлено примыкание элзментов раскосной решетки к верхнему и нижнему по сам.Known farm has the disadvantage that inefficiently carried out the junction of the ellipse diagonal lattice to the upper and lower themselves.
Цель изобретени - повыгление жесткости конструкции фермы и . обеспечение возможности использовани выступов дл опирани кровли .The purpose of the invention is to increase the rigidity of the truss structure and. enabling the use of protrusions to support the roof.
Достигаетс это тем, что продольные выотупы выполнены о плоскии опорным столикой и расположены на вертикальных стенках ниже горизонтальной оси симметрии.This is achieved by the fact that the longitudinal outcrops are made on a flat supporting table and are located on the vertical walls below the horizontal axis of symmetry.
На фиг, I изображена предложенна ферма (примыкание раскосов к верхнему по су)} на фиг. 2 то же, (примыкание раскосов к нижнему по су) на фиг. 3 - верхний по с, поперечное сечение.Fig. I shows the proposed truss (junction of the diagonals to the upper cus)} in fig. 2 is the same, (junction of braces to the lower in cus) in FIG. 3 - upper along with cross section.
Ферма из гнутых замкнутых профилей включает верхний I и нижний 2 по са, центр т жести которых смешен к нижним стенкам, к которым примыкают раскосы 3, Боковые стенг кй 4 гнутых профилей имеют продольные выступы 5 с плоскими опорными столиками б.The farm of bent closed profiles includes the upper I and lower 2 portions, the center of the plate of which is mixed to the lower walls, to which the braces 3 are adjacent. The lateral walls of the 4 curved profiles have longitudinal projections 5 with flat supporting tables. B.
За счет снижени центра т жес ти раскосы 3 сближаютс , обеспечива оптимальные услови примыкани а у нижнего по са раскосы раздви гаюто на величину, достаточную дл примыкани непосредственно к стенке по са стойки 7, При этом соблюдаетс условие пересечени By reducing the center of gravity, the braces 3 approach each other, providing optimal conditions for abutment and at the lower section, the braces are spread out by an amount sufficient to adhere directly to the wall of the post 7. At the same time, the condition of intersection
