A top frame 5 is fixedly arranged on the middle top surface of the longitudinal beam assembly 1.

[0044] The longitudinal beam assembly 1 provided by the present application is a bidirectional variable cross-section longitudinal beam, so that the cross-sectional area of the longitudinal beam assembly 1 in the transverse direction and the longitudinal direction is not the same, thereby better bearing the longitudinal and transverse forces, thereby improving the carrying capacity of the whole frame. The top frame structure 5 provided by the present application can improve the torsional performance of the whole frame in combination with the longitudinal beam assembly 1, and also strengthen the local strength of the transition roof.

[0045] In the embodiment of the present application, referring to the drawings Figure 3As shown, the longitudinal beam assembly 1 of the present application comprises a left longitudinal beam 11, a right longitudinal beam 12 and a first rectangular tube 13 fixed between the left longitudinal beam 11 and the right longitudinal beam 12 to make the left longitudinal beam 11 and the right longitudinal beam 12 symmetrically arranged, the number of the first rectangular tube 13 used in the present application is not less than 8, and the width between the left longitudinal beam 11 and the right longitudinal beam 12 of the present application is 2000mm. Since the first rectangular tube 13 of the present application is a rectangular tube profile, and the first rectangular tube 13 is vertically arranged to the left longitudinal beam 11 and the right longitudinal beam 12 respectively, the stiffness and bending resistance of the frame are improved.
