Horizontal frame and vertical frame connection structure of T-shaped steel joist
Provided is a horizontal frame and vertical frame connection structure of a T-shaped steel joist. The problems that the deformation caused by the whole welding of the T-shaped steel joist occurs, and the strength in large wind load positions cannot meet engineering requirements are solved. The horizontal frame and vertical frame connection structure comprises a T-shaped steel joist horizontal frame composed of a horizontal frame end plate and a horizontal frame rib plate, a T-shaped steel joist vertical frame composed of a vertical frame end plate and a vertical frame rib plate and pins. The horizontal frame and vertical frame connection structure is characterized in that cool-roll steel sheets with equivalent thickness are adopted for the section bars of the horizontal frame rib plate, the vertical frame rib plate, the horizontal frame end plate and the vertical frame end plate, the end portions of adjacent horizontal frame rib plates are provided with horizontal blind holes with built-in springs, the horizontal blind holes and through holes of the vertical frame rib plate are on the same axis, and the pins are utilized to be aligned and connected with the horizontal blind holes at the end portions of the horizontal frame rib plates to enable the inner side surfaces of the rib plates connected with each other to be on the same plane and the outer side surfaces of the end plates connected with each other to be on the same plane. The horizontal frame and vertical frame connection structure is reasonable in structural design, convenient and quick to operate and reliable and regular in connection, reduces cost, improves working efficiency, meets engineering requirements of the joist strength and improves appearance aesthetics of the joist serving as an indoor visible joist.
