Embodiment Construction
[0036] The present invention will be described in further detail below in conjunction with specific embodiments.
[0037] Such as figure 1 As shown, the prefabricated double-sided slab-type all-bolt steel coupling beam of the present invention includes a multi-cavity concrete-filled steel pipe composite column 5, and two horizontally fixed side plates 6 are arranged opposite to each other and symmetrically on a pair of multi-cavity steel-filled concrete composite columns 5. , the side plate 6 is connected to a full-bolt steel composite beam through a number of shear bolts 7 .
[0038] Such as figure 2 As shown, the all-bolt shaped steel composite beam of the present invention comprises an H-shaped steel beam 1, and two stiffening plates 4 are respectively arranged between the shaped steel flanges at both ends of the H-shaped steel beam 1, and the stiffening plates 4 are fixed on the H-shaped steel beam. Both sides of the web of beam 1. Channel steel 3 is respectively welde...

The invention discloses a fabricated double-side-plate full bolt steel coupling beam which comprises a pair of multi-cavity steel pipe concrete combination columns, two side plates fixed horizontally are oppositely and symmetrically arranged on the pair of multi-cavity steel pipe concrete combination columns correspondingly, and the side plates are connected with a full bolt type steel combination beam through a plurality of shear resistance bolts. The fabricated double-side-plate type full bolt steel coupling beam has seismic performance, has necessary strength, good deformability and energy dissipation capacity and is high in degree of assembly, high in energy dissipation capacity and good in ductility.
Description
technical field [0001] The invention relates to an assembled double-side plate type all-bolt steel connecting beam, which is mainly applied to the steel connecting beam of multi-storey and high-rise buildings in building structures. Background technique [0002] In recent years, with the acceleration of my country's reform and opening up, many complex high-rise buildings have emerged. Reinforced concrete structures have been widely used in such buildings. Reinforced concrete structures have the advantages of high rigidity, low cost, high strength, and flexible layout. A high-rise building structure system in line with my country's national conditions. However, shear failure often occurs in reinforced concrete coupling beams, resulting in serious degradation of strength, stiffness and energy dissipation capacity after failure. [0003] It is a new type of structure to use steel connecting beams instead of concrete connecting beams. Relevant test and theoretical research concl...
