Description

Technical Field

[0001] The utility model belongs to the technical field of factory building construction, and in particular relates to a truss connection structure for factory building construction. Background Art

[0002] During the construction of a factory building, a large number of trusses are generally used and arranged on the top of the factory building frame. The two ends of the trusses are generally fixed to the upper side of the main beam by bolting and welding. During the construction of a factory building, a large number of steel frame structures are used. Due to the deformation during erection and the differences between the steel frame structures themselves, the trusses spanning the upper side of the main beams on both sides will have certain differences in height. This will have a certain adverse effect on the laying of the top beam on the upper side of the truss, and will cause some of the lower trusses to fail to support the top of the factory building in place in the later stage.
