The invention discloses a suspension connection node for a large-span cantilevered steel truss and a construction method thereof. The bottom end of the steel corbel is provided with vertical column lugs, the end of the steel corbel away from the steel pipe column is provided with a web, one end of the cantilevered main beam is connected to the web, and the end of the cantilevered main beam is far away from the steel pipe column There are beam joints, which are used to connect the side beams perpendicular to the cantilevered main girder. The top of the cantilevered main girder is fixed with beam ear plates, and the two ends of the temporary steel tie rods are respectively fixed with connecting plates. The two connecting plates are respectively It is fixedly connected with the column ear plate and the beam ear plate, and the structure is constructed from bottom to top. Temporary steel tie rods are used to assist in the layer-by-layer installation and adjustment of the cantilevered main beam. And safety protection, the suspension structure is constructed layer by layer in a bottom-up order, which is convenient for component installation and improves efficiency.
Description
technical field [0001] The invention belongs to the field of large-span cantilevered steel truss suspension structures, and particularly relates to a large-span cantilevered steel truss suspension connection node and a construction method thereof. Background technique [0002] With the development of the construction industry, more and more architects have broken the tradition and pursued the design of houses with large overhangs, large spaces, and high permeability. The structural system of steel trusses on the whole floor of the roof and high-strength steel rods at the ends of the trusses suspends three-story large cantilevered steel beams and floor slabs. The cross-section is optimized, and at the same time, it satisfies the permeability of the building's interior space and facade, creating a large column-free space for the interior. [0003] According to the mechanical characteristics of the suspended structure system, the traditional construction sequence is to complet...
