Description

Connecting node of corridor steel beam and main body structure Technical Field The utility model relates to the field of steel structure buildings, in particular to a connecting node of a corridor steel beam and a main body structure. Background Along with the high-speed development of the economy and the change of the social demands of China, the building design of the high-rise building structure is developed from single-function application to comprehensive multipurpose while the high-rise building structure is developed towards high-level, high-strength, combined structure and the like. The use of multiple functions and the aesthetic requirements of buildings necessarily lead to complex variability in the structural body and form, especially in the planar and elevational body forms of high-rise buildings. In recent years, a plurality of steel structural bodies of a large chassis are connected with each other by a corridor steel girder in an increasing number of structural forms. In the prior art, the vestibule girder steel all overlap joint is on the plummer of steel construction major structure, when the vestibule girder steel span is great and/or set up highly higher, all put forward very high requirement to the bearing capacity of plummer and the reliability of being connected of vestibule girder steel and plummer, especially when the vestibule girder steel sets up the position higher, under the effect of strong wind etc., the vestibule girder steel can take place to rock, exists the possibility of collision with steel construction major body, makes the stability that the vestibule girder steel is connected receive certain influence, exists the potential safety hazard.
