Steel structure box beam connection joint assembling device and an assembling method thereof

Abstract

The invention discloses a steel structure box girder connection node assembling device, Including box girder, box corbel, Webs, connecting plates and mounting bolts, The box girder and the web of thebox corbel are provided with mounting bolt holes adapted to the connecting plate and the mounting bolts, and the connecting plate is arranged on the inner side of the web, and the top and bottom of the box girder and the top and bottom of the box corbel are respectively welded with an upper flange plate and a lower flange plate, which relate to the technical field of construction. A method for assemble that connecting joint of the steel structure box gird it avoids that the positioning of the connection between the corbel and the box girder depends on the skill level and experience of the operator, After temporary positioning, local adjustment is carried out by means of crowbars and other tools, and initial fixation is carried out by spot welding, so as to ensure the connecting quality ofthe box-shaped corbel and the box-shaped beam, thereby preventing the groove assembly size of the connecting joint and the integral welding quality from being affected, and facilitating the weld formation of the lower flange plate at the same time.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to an assembling device and an assembling method for connecting nodes of steel structure box girders. Background technique [0002] The cross-sectional shape of a box girder is the same as that of a normal box, so it is called a box girder. It is generally composed of a cover plate, a web, a bottom plate and a partition. When it is large, the box girder is the best structural form. Its closed thin-walled section has a large torsional rigidity, which is beneficial to curved bridges and bridges constructed with cantilever construction. Both the top and bottom plates have large areas and can effectively resist Positive and negative bending moments meet the needs of reinforcement, with good dynamic characteristics and small shrinkage deformation. In recent years, large-span complex public buildings such as stadiums, conference and exhibition centers, airport terminals, high-rise an...
