Title
(EN) IMPROVED BEAM
(RU) УЛУЧШЕННАЯ БАЛКА
Abstract
(EN) FIELD: construction industry.SUBSTANCE: invention refers to construction industry, and namely to channel beam with hollow flanges located along opposite ends of beam web and passing from this web in one direction. Aim of this invention is to eliminate drawbacks of common all-service building beams. Channel beam with hollow flanges consists of flat web with two narrow rectangular cross-section flanges which are located along opposite edges of the above web and pass in one direction normal to surface of this web. Beam has the following optimum parameter ratios: Wf=(0.3)Db, Wf=(3.0)Df and Wf=(30)t.EFFECT: producing building beam being more useful for consumer in comparison to available all-service building beams.29 cl, 25 dwg, 3 tbl
(RU) Изобретение относится к области строительства, а именно к швеллерной балке с полыми полками, расположенными вдоль противоположных краев балочной стенки и проходящими от этой стенки в одном направлении. Целью данного изобретения является преодоление недостатков известных строительных балок универсального назначения и создание строительной балки, обладающей большей полезностью для потребителя по сравнению с существующими строительными балками универсального назначения. В изобретении предложена швеллерная балка с полыми полками, содержащая плоскую стенку с двумя узкими полками прямоугольного сечения, которые расположены вдоль противоположных краев указанной стенки и проходят в одном направлении перпендикулярно поверхности этой стенки. Балка имеет следующие оптимальные соотношения параметров: Wf=(0,3)Db, Wf=(3,0)Df и Wf=(30)t. 28 з.п. ф-лы, 23 ил., 3 табл.
