Изобретение относитс к строитель ству и используетс дл изготовлени предварительно напр женных железобетонных конструкций.The invention relates to construction and is used to manufacture prestressed reinforced concrete structures.
Целью изобретени вл етс повышение степени предварительного напр жени конструкции и ее прочности.The aim of the invention is to increase the degree of prestressing of the structure and its strength.
На чертеже показана напр гаема конструкци в форме во врем бетонировани , разрез.The drawing shows the stress structure in the mold during concreting, the slit.
Способ включает удлинение напр гаемой арматуры t, закрепленной анкерами 2 на подвижных торцовых щитах 3 замкнутой формы , снабженной вибропоршнем 5 с шарниром 6 и ограничител ми 7, установленной на вращатель йом стенде 8 и содержащей бетонную смесь 9.The method includes lengthening the tension fittings t fixed by anchors 2 on movable end shields 3 of a closed form, equipped with a vibrating piston 5 with a hinge 6 and limiting 7 mounted on a rotator with a stand 8 and containing a concrete mix 9.
Бетонна смесь 9, загруженна в быстро вращающуюс форму 4, под действием центробежных сил отбрасываетс к ее подвижным торцовым щитам 3, уплотн етс и раздвигает эти щиты, удлин закрепленную по концам анкеРедактор Н. ГорватConcrete mix 9, loaded into a rapidly rotating form 4, under the action of centrifugal forces, is thrown to its movable face shields 3, compacted and pushes these shields, the extension fixed at the ends of the anchor.
