Description
Предлагаемый способ возведени сводов и арок заключаетс в закладке нат жении арматуры дл создани пфедварительно напр женных железобетонных участков сводов н арок в местах возможного по влени раст гивающих усилий.The proposed method of erecting arches and arches consists in laying down the tension of the reinforcement to create reinforced concrete reinforced sections of the arches of the arches in the places of the occurrence of tensile forces.
Особенность этого сносо,ба состоит в том, что бетонирование (кладка) свода п нат женне арматуры ведетс секцн ми, нричем, бетонирование очередно секции нроизводитс носле нат :Ке1н-1 арматуры предыдундей секции.The peculiarity of this demolition, ba, is that the concreting (laying) of the roof of the reinforcement is carried out by sections, and concreting of the next section is produced nosle nat: Ke1n-1 reinforcement of the previous section.
Такой снособ дает возможность нримепить в сводах нр молинейиую арматуру, упростить нат жение и создать нредваритслькое напр жение в своде.Such a method allows the installation of moline reinforcement in arches, simplifying the tension and creating a moderate stress in the roof.
На чертеже изображен предварителыю напр женный свод с арматурой .The drawing shows a prestressed arch with reinforcement.
В опору закладываютс пр мые стержни 1 из стали Дл нат жени секции 2 свода- От п ты до аикерных колонок 3 стержни арматуры вставл ютс в трубки. Затем устанав.чиваютс стержни 4 арматуры дл второй секции свода 5. Арматура изолируетс трубкой от сцеплени с кладкой. После того как кладка первой секции свода доcTiiiTieT достаточно прочности, нат же 1ие арматур во второй секции, причем реакци передаетс на кладку, чем создаютс 1редварительные сжимающие напр жени в секции. В зависимости от размеров и радиуса кривизны свода назначаетс количество подлежащих армироваии о клиньев в п те (в обычных с.туча х не более двух).Straight rods 1 of steel are put in the support. To tension section 2 of the roof - From the end to the active columns, 3 reinforcement rods are inserted into the tubes. Then, the reinforcement rods 4 for the second section of the roof 5 are installed. The reinforcement is insulated by a tube from the bond with the masonry. After the masonry of the first section of the arch is sufficiently strong, tension is only one of the fixtures in the second section, and the reaction is transferred to the masonry, which creates preliminary compressive stresses in the section. Depending on the size and radius of curvature of the roof, the number of wedges to be fixed in fi is assigned (in ordinary c. Tires no more than two).
Одновременно с этим ведетс работа но кладке свода в ключе, последовательно в направлении к п там.At the same time, work is being carried out on the laying of the vault in the key, successively in the direction to the n.
Таким образом, кладка сводов ироизводитс одновременно у обеих п т свода и в ключе.Thus, the laying of the vaults is produced simultaneously in both of the n and v keys in the key.
После того, как R. наибольших раст гивающих напр жений в п тах и в кл че-свола возведены предварительно напр женные секции, участок свода б гежду ними заполн етс бетонной или каменной кладкой без -п-редвари|ельного напр жени . After the R. of the greatest tensile stresses in the heights and in the Chevola region, the prestressed sections were erected, the section of the arch between them is filled with concrete or masonry non-redundant tension.
По предлагаемому-способу своды могут быть выполнены посто нной толщины, так как напр жени в н тах будут регулироватьс предварительным напр жением.In the proposed method, the arches can be made of constant thickness, since the stresses in the stresses will be adjusted by the prestressing.
Предмет изобретени Subject invention
Способ возведени предварительно напр женных железобетонных или железокаменных сводов и арок с нат жением арматуры после отвердени бетона или каменной кладки, отличающийс тем, что бетонирование (Котадку) свода или арки и нат жение арматуры производ т последовательными секци ми (клинь ми), причем бетонирование (кладку) каждой секции нроизвод т после нат жени арматуры соседней секции.A method of erecting prestressed reinforced concrete or iron-stone arches and arches with tensioning the reinforcement after the concrete or masonry has hardened, characterized in that the concrete (arch) or arch and tension of the reinforcement are produced by successive sections (wedges), and the concrete ( laying) of each section is produced after tensioning the reinforcement of the adjacent section.
