Description
В существующих напр женно армированных железобетонных конструкци х с арматурой из проволоки, устанавливаемой до бетонировапи , закрепление арматуры производитс при помощи системы анкеров или без анкеров, но с применением высокопрочной проволоки диаметром не более 2,5 мм и бетона высоких марок.In existing reinforced reinforced concrete structures with wire reinforcement installed before concreting, the reinforcement is fixed using anchors or without anchors, but using high-strength wire with a diameter of not more than 2.5 mm and high-grade concrete.
В первом случае изготовление элементов усложн етс необходимостыо устройства анкеров. Во втором случае требуетс значительный расход высокосортного цемента.In the first case, the manufacture of elements complicates the need for anchors. In the second case, a significant consumption of high-grade cement is required.
Особенностью предлагаемой конструкции вл етс то, что на трубчатой части фланцев, установленных i:a концах элемента, сделаны выступы (колки), на которые наматываетс при изготовлении непрерывна продольна арматура элемента.A feature of the proposed design is that on the tubular part of the flanges installed i: a the ends of the element, protrusions (grooves) are made on which a continuous longitudinal reinforcement of the element is wound during manufacture.
На фиг. 1 изображен конец трубчатого элемента, вид в перспективе; на фиг. 2 - элемент в поперечном сечении при формовке.FIG. 1 shows the end of the tubular element, a perspective view; in fig. 2 - element in cross section during molding.
Трубчатый элемент состоит из фланцев / с косынками 2 и патрубками 3, к которым приварены колки 4 дл намотки напр женной арматуры 5. Во врем изготовлени трубчатых элементов фланцы с патрубками и колками через установочное кольцо 6, болты 7 и вкладыши 8 опираютс на кассету 9. На колки 4 навиваетс напр женна арматура 5. Усили от нат нутой арматуры в процессе изготовлени элемента передаютс -кассете. После бетонировани трубы на станке и предварительцого твердени бетона кассета удал етс . Дл этого с помощью домкрата подт гиваетс установочное кольцо 6, разболчиваютс болты 7, убираютс БКладЫЩи 8; затем кольцо 6 удал етс . Стыкование железобетонных труб в процессе их мо тажа производитс путем фланцев.The tubular element consists of flanges / with kerchiefs 2 and nozzles 3, to which pegs 4 are welded for winding tensioned reinforcement 5. During the manufacture of tubular elements the flanges with nozzles and pegs through the adjusting ring 6, the bolts 7 and liners 8 rest on the cartridge 9. The armature 5 is wound on the pegs 4. The forces from the tensioned armature during the manufacturing process of the element are transferred to the cassette. After the concrete has been concreted on the machine and the concrete has previously hardened, the cassette is removed. To do this, use a jack to tighten the adjusting ring 6, loosen the bolts 7, remove the attachment 8; then ring 6 is removed. The joining of reinforced concrete pipes during their assembly is carried out by means of flanges.
Предварительно напр женный железобетонный трубчатый элемент с металлическими фланцами, к которым присоединена продольна армаПредмет изобретени Pre-stressed reinforced concrete tubular element with metal flanges to which a longitudinal armature is attached.
