The connecting position is connected to one end of the inclined beam 112, the second connecting position is connected to one end of the cross beam 113, and the other end of the inclined beam 112 is connected to the other end of the cross beam 113 to form a triangular truss structure, and the two truss beams 11 are symmetrically arranged on the main beam 12 On both sides, the symmetrical structure can carry loads more reasonably, so that the superstructure has higher stability; the connection between the truss beam 11 and the main beam 12 is realized through the detachable connection between the connecting body 111 and the main beam 12 .

As shown in Figure 1 or Figure 3, in order to further strengthen the load bearing capacity of the stability of the upper structure, several vertical purlins 114 are also arranged between the inclined beam 112 and the cross beam 113, and between the first connection position and the second connection position The distance between them is greater than the height of the vertical purlins 114. Specifically, the crossbeam 113 is arranged perpendicularly to the connecting body 111, and the inclined beam 112 is arranged obliquely to the connecting body 111, that is, the distance between the inclined beam 112 and the crossbeam 113 is the largest on the connecting body 111 side, and the distance decreases along the length direction of the crossbeam 113. Through the arrangement of the vertical purlins 114 , a grid structure is formed, which shares the vertical load on the inclined beams 112 and improves the stability and bearing capacity of the truss beam 11 structure.
