Suspension connecting joint for large-span cantilever steel truss and construction method thereof

Abstract

The invention discloses a suspension connecting joint for a large-span cantilever steel truss and a construction method of the suspension connecting joint. The suspension connecting joint comprises steel pipe columns, cantilever main beams, temporary steel pull rods and fixing steel pull rods. Steel corbels are arranged at the side ends of the steel pipe columns, vertical column lug plates are arranged at the bottom ends of the steel corbels, and web plates are arranged at the ends, far away from the steel pipe columns, of the steel corbels. One end of each cantilever main beam is connected tothe corresponding web plate, and beam joints are arranged at the ends, far away from the steel pipe columns, of the cantilever main beams and used for being connected with edge beams which are perpendicular to the cantilever main beams. A beam lug plate is fixedly arranged at the top end of each cantilever main beam. Connecting plates are fixedly arranged at the two ends of each temporary steel pull rod, the two connecting plates of each temporary steel pull rod are fixedly connected with the corresponding column lug plate and the corresponding beam lug plate. The structure is constructed inthe forward direction from bottom to top, the temporary steel pull rods are adopted to assist in layer-by-layer installation and adjustment of the cantilever main beams, component hoisting is furtherprotected, an operator has a working face and safety protection, the suspension structure is constructed layer by layer from bottom to top in sequence, component installation is facilitated, and the efficiency is improved.

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...
