Description
Известно, что сварные соединени железобетонных конструкций при статической нагрузке имеют высокую прочность, что обеспечивает достижение равнонрочности узлов и стыков в сварной арматуре. Однако прочность таких соединений нри неременной нагрззке недостаточна, что обусловливаетс геометрической формой сварных соединений, отличающихс наличием довольно острых концентраторов напр жений.It is known that welded joints of reinforced concrete structures under static load have high strength, which ensures the uniformity of the nodes and joints in the welded reinforcement. However, the strength of such joints at the inadequate load is insufficient, which is due to the geometric shape of the welded joints, characterized by the presence of rather sharp stress concentrators.
Предлагаемый способ контактной сварки арматурных стержней встык или вкрест новышает вибрационную прочность сварного соединени по сравнению с известными способами.The proposed method of resistance welding of reinforcing bars butt or cross-wise increases the vibration strength of the welded joint in comparison with known methods.
Это достигаетс тем, что перед сваркой или после сварки сварное соединение подвергают обжатию в формах, придающих местам усиле-. ни сечени плавные очертани .This is achieved by the fact that, before welding or after welding, the welded joint is subjected to compression in forms that give the places strength. no section smooth outlines.
Способ может быть выполнен в двух вариантах.The method can be performed in two versions.
На фиг. 1 приведена схема, по сн юща осуществление способа по одному варианту; на фиг. 2 и 3-схемы, по сн ющие осуществление способа по другому варианту.FIG. 1 is a schematic diagram explaining the implementation of the method according to one embodiment; in fig. 2 and 3 diagrams explaining the implementation of the method in another embodiment.
Контактна сварка по первому варианту производитс следующим образом. Сварка стыков арматурных стержней / и 2 вынолн етс в два этажа на модернизированных контактных стыковых мащинах, снабженных формующим устройством 3. Вначале производитс контактна сварка стержней 1 и 2 (позици а па фиг. 1), а затем сваренный и наход щийс в раскаленном состо нии стык обжимаетс с помощью усилий Р формующим устройством 3. При эгом стыку придаетс форма с плавными переходами, котора обеспечивает устранение острых концентраторов напр жений. Формовка может производитьс с дополнительным нагревом стыка током стыковой машины.Contact welding in the first embodiment is as follows. The welding of the joints of reinforcing rods / and 2 is carried out in two floors on modernized contact butt masks equipped with a forming device 3. First, contact welding of rods 1 and 2 (position pa in Fig. 1) is performed, and then welded and in a hot condition. The junction is crimped using the forces P of the forming device 3. In this way, the junction is shaped with smooth transitions, which ensures the elimination of sharp stress concentrators. Forming can be done with additional heating of the joint by the current of the butt machine.
Контактна сварка цо второму варианту осуществл етс следующим путем.Contact welding tso the second option is carried out in the following way.
Арматурные стальные стержни 4 и 5 в местах сварки утолщаютс , а утолщенные части стержней формуютс (фиг. 2, позиции аи в). Затем стержни свариваютс в местах утолщени (фиг. 2, позиции б и г). В результате неровности сварных соединений оказываютс расположенными в усиленном сечении, и при переменной нагрузке эти соединени болееReinforcing steel rods 4 and 5 at the weld sites are thickened, and the thickened parts of the rods are molded (Fig. 2, positions a and c). The rods are then welded at the thickening sites (Fig. 2, positions b and d). As a result, the irregularities of the welded joints are located in a reinforced section, and at variable load these joints are more
