TECHNICAL FIELD

[0001] The application belongs to the technical field of steel structure, and particularly relates to a connecting auxiliary device for a fabricated steel structure house special-shaped column and a welding process thereof. BACKGROUND

[0002] Steel structure is a structure composed of steel materials, and is one of main building structure types. The structure is mainly composed of members such as steel beams, steel columns and steel trusses made of profiled steel and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying and galvanizing. Welding seams, bolts or rivets are usually used to connect between various members or parts. The steel structure is widely used in fields such as large workshops, venues and super high-rise buildings due to its light weight and simple construction.

[0003] The special-shaped column refers to a column with different geometric section shapes such as T, L and Z cross-shaped section column under the premise of meeting the requirements of structural rigidity and bearing capacity according to the requirements of building use function and building design arrangement. Due to the existence of multiple limbs, the shear center of the special-shaped column is usually not coincided with the section centroid, and under the stress state, each limb generates warping normal stress and shear stress. Due to the shear stress, the column limb concrete cracks earlier than the ordinary rectangular column, that is, the web shear crack is generated, which makes the special-shaped column brittle and reduces the deformation capacity of the special-shaped column compared with the ordinary rectangular column.

[0004] In the prior art, the fabricated building pre-fabricates part or all of the members in the factory, and then transports them to the construction site for assembly. After the pre-fabricated members are transported to the construction site, the special-shaped column is overlapped and poured to ensure safety. However, during the entire fabricated building construction process, the entire special-shaped part is usually placed at the desired position by manual operation, and then assembled, which easily causes the positioning difficulty of the special-shaped column and reduces the shear and compression resistance of the steel structure.
