Изобретение относитс к строительству , а именно, к короэиестойким строительным конструкци м npoNbauineH- ных зданий и сооружений.The invention relates to the construction, in particular, to the durable building structures of npoNbauineH buildings and structures.
Наиболее близким по технической сущности к изобретению вл етс предварительно напр женна балка, включающа бетонный сердечник имеющий поверху и понизу каналы с предварительно напр женной арматурой и армированную полимербетонную оболочКУ 1.The closest to the technical essence of the invention is a prestressed beam, comprising a concrete core having on top and bottom channels with prestressed reinforcement and reinforced polymer concrete sheath 1.
Известен также способ изготовлени предварительно напр женной балки , включающий сборку блоков и нат жение арматуры 2.A method of manufacturing a prestressed beam is also known, including the assembly of blocks and the tension of reinforcement 2.
Недостатком известного решени балки вл етс недолговечность конструкции .A disadvantage of the known beam solution is the fragility of the structure.
Цель изобретени - повышение прочности и долговечности конструкции.The purpose of the invention is to increase the strength and durability of the structure.
Поставленна цель достигаетс тем, что в предварительно-напр женной балке, включающей бетонный сердечник имеющий понизу и поверху каналы с предварительно напр женной арматурой, и армированную полимербетонную оболочку, бетонный сердечник выполнен составным по из блоков, внутренние торцы которыхThe goal is achieved by the fact that in a prestressed beam, including a concrete core, having lower and top channels with prestressed reinforcement, and a reinforced polymer concrete shell, the concrete core is made of composite blocks, the inner ends of which
снабжены закладными металлическими пластинами, выполненными по цилиндрической поверхности, а торцы сердечника - анкернь устройствами дл закреплени напр гаемой арматуры по KOHUciM балки.they are equipped with embedded metal plates made on a cylindrical surface, and the ends of the core are anchored with devices for fastening tensioned reinforcement along KOHUciM beams.
Кроме того, блоки снабжены цилиндрическими вкладышами из спирально армированного бетона, расположенными In addition, the blocks are equipped with cylindrical liners of spirally reinforced concrete, located
10 наклонно по сжатой диагонали в крайних блоках и горизонтально - в сжатой зоне промежуточного блока, а по раст нутой диагонали крайних блоков наклонной арматурой, приваренной к 10 obliquely along the compressed diagonal in the extreme blocks and horizontally in the compressed zone of the intermediate block, and along the extended diagonal of the extreme blocks with oblique reinforcement welded to
15 их торцам.15 of their ends.
Балка.изготовлена способом, включающим сборку блоков и нат жение арматуры , причем после сборки блоков закрепл ют нижнюю рабочую арматуру, The beam is made by a method including assembly of blocks and tension of reinforcement, and after assembling the blocks the lower working reinforcement is fixed,
20 а ее нат жение производ т за счет поперечного перемещени блоков вкладыша , приложенным в стыках поперечным усилием до соприкосновени блоков между собой на уровне верхней 20a, its tension is due to the transverse movement of the blocks of the liner, applied in the joints by a transverse force before the blocks touch each other at the level of the upper
