Steel beam lifting point center moving type construction method
The invention provides a steel beam hoisting point center movable type hoisting construction method. Long steel beam components and short steel beam components are included. The long steel beam component comprises a long steel beam and a steel beam foundation. The inner end of the long steel beam is fixedly connected to the steel beam foundation. The short steel beam component comprises a short steel beam and a steel beam foundation. The inner end of the short steel beam is fixedly connected to the steel beam foundation. During construction, the short steel beam is adopted as the counter weight and is connected to the outer end of the long steel beam, so that when the long steel beam is hoisted, the center of a hoisting point moves to the outer side of an existing viaduct, interference of an existing bridge structure on installation is avoided, and the cost needed for manufacturing the counter weight is saved; meanwhile, the temporary supporting frame is erected on the outer side of the steel beam foundation of the long steel beam, the long steel beam can be used for temporarily supporting the long steel beam during installation, the long steel beam with the balance weight is not prone to deviation during installation, a constructor can conveniently adjust the position of the inner end of the long steel beam on the steel beam foundation, and therefore the effects of accurate installation and installation quality improvement are achieved.
本发明提出一种钢梁吊点中心移动式吊装施工方法，包括长钢梁构件以及短钢梁构件；长钢梁构件包括长钢梁和钢梁基础，长钢梁内端固定连接于钢梁基础上；短钢梁构件包括短钢梁和钢梁基础，短钢梁内端固定连接于钢梁基础上；施工时，本发明采用短钢梁作为配重，连接于长钢梁的外端，以使吊装长钢梁时，吊点中心移动至现有高架桥外侧，从而避免了现有桥梁结构对安装的干涉，且节约了制造配重所需的成本；同时，在长钢梁的钢梁基础外侧架设临时支撑架，长钢梁安装时可用于临时支撑长钢梁，使带有配重的长钢梁安装时不易发生偏移，以便施工人员调节长钢梁内端在钢梁基础上的位置，从而起到准确安装、提高安装质量的作用。
