Primary and secondary beam rigid connection joint for wave web steel structure
The invention discloses a primary and secondary beam rigid connection joint for a wave web steel structure, belongs to building structural components, and particularly relates to a steel structure connecting joint. The primary and secondary beam rigid connection joint for the wave web steel structure comprises a wave web steel structure primary beam, wave web steel structure secondary beams and a joint bolt connecting structure. The primary beam and the secondary beams are connected in a flush joint mode, and the top face of a primary beam upper flange plate is flush with the top faces of secondary beam upper flange plates. A flange plate connecting plate is arranged at the connecting position of the primary beam and the secondary beams, secondary beam flange plates and the connecting plate are connected through high-strength bolts, and accordingly the secondary beam bending moment can be transmitted. A primary beam wave web is provided with vertical bar-shaped holes and is welded with a joint plate at the connecting position, and the ends of secondary beam wave webs are connected with the joint plate via a flat web through high-strength bolts. According to the primary and secondary beam rigid connection joint for the wave web steel structure, the wave webs have small compressive rigidity in the corrugated direction, the normal force can be rarely borne, and bending under the axial load effect is avoided; large lateral rigidity is achieved in the direction perpendicular to the corrugated direction, and the overall anti-bending and anti-shearing bearing capacity of a steel beam under the vertical load effect can be improved obviously.
