DETAILED DESCRIPTION
[0011] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.
[0012] Based on the stress mode of the lightweight partition wall steel frame and the grid structure, when the plane positions of the partition wall and the upper and lower chords of the grid do not correspond, the connection method between the wall steel frame and the grid becomes a problem. The purpose of the present invention is to make the connection between the lightweight partition wall steel frame and the grid structure simple and convenient to achieve and ensure the reliability of the connection.
[0013] Embodiment.

[0016] The transverse steel beam 12 and the longitudinal steel beam 13 are square steel tube structures.
[0017] Based on the principle that the rods of the grid structure cannot be bent and the external force must be applied to the ball nodes, transverse and longitudinal steel beams are added at the ball nodes of the upper and lower chords of the grid through the conversion of hanging supports, and the longitudinal steel beams are used as the fulcrums of the lightweight partition keel columns, and the partition keel columns are fixed to the longitudinal steel beams through connecting plates and bolts. In addition, the transverse and longitudinal steel beams are both made of square steel pipes, which can better solve the problem of bending resistance inside and outside the plane.
