The main structure 20 includes a structural body 21 and a first cross brace 22 connected to the structural body 21, one end of the first cross brace 22 is connected to the truss 10, and the main structure 20 provides the truss 10 with an oblique supporting force inclined with respect to the longitudinal direction of the truss 10 through the first cross brace 22. Specifically, an end of the first cross brace 22 facing away from the truss 10 extends toward a side away from the truss 20 in a direction in which the truss 10 is directed toward the main body structure 20. Thus, the diagonal support provided by the first cross diagonal brace 22 is more stable and has a better effect on the truss.
It should be noted that, in the embodiment of the present application, referring to fig. 1, in the vertical direction, that is, the direction perpendicular to the paper plane, the truss 10 has a first plane a and a second plane B, and the first plane a and the second plane B are disposed at an angle, so that the direction in which the truss 10 points to the main body structure 20 may be the direction in which the horizontal left or right direction of the first plane a in the drawing points to the main body structure 20, or the direction in which the horizontal direction of the second plane B in the drawing points to the main body structure 20, and therefore, the direction in which the truss 10 points to the main body structure 20 is determined according to the shape of the truss 10, so that there are cases of multiple pointing directions, and the specific pointing direction is determined according to the position of the first cross brace relative to the truss 10.
In the embodiment of the present application, the structural body 21 is a reinforced concrete structure. It should also be noted that, since the main structure 10 is a unitary structure, the first cross brace 22 is not independent from the exterior of the structural body 21, but is integral with the structural body 21.
In this way, by providing the first cross diagonal brace 22, the diagonal resistance of the main structure 20 can be enhanced, so that the diagonal component force of the truss 10 acting on the main structure 20 can be balanced by the first cross diagonal brace 22, thereby eliminating the design of deformation joints and sliding supports, rigidly connecting the large-span truss 10 and the main structure 20, and further not affecting the building facade. In addition, the deformation joint is eliminated, so that the influence on the attractiveness of the building is avoided, the cost caused by the deformation joint treatment is saved, the service life of the sliding support usually cannot reach the service life of the main structure 20, particularly the service life of the main structure 20 is 100 years, and therefore the whole service life of the large-span truss structure system 100 can be prolonged by eliminating the sliding support, and the safety of the main structure is guaranteed.

Specifically, when the building floor is sufficiently high, the single brace 221 may be used, and when the building floor is insufficiently high, the V-shaped brace 222 may be used. As such, the first cross brace 22 can be adaptively adjusted according to different application scenarios.
In some embodiments, the main structure 20 includes a steel reinforced concrete beam 23, the steel reinforced concrete beam 23 is connected to the structural body 21, and the main structure 20 resists a tensile force from the girder 10 through the steel reinforced concrete beam 23. Specifically, one end of the steel reinforced concrete beam 23 is connected to the girder 10, and the steel reinforced concrete beam 23 extends in parallel with a direction in which the girder 10 is directed toward the main body structure 20.
It should also be noted that one end of the steel reinforced concrete beam 23 is connected to the chord member 11 of the truss 10, and the pulling force of the truss 10 on the main structure 20 is provided by the chord member 11.
In addition, the specific pointing direction is determined according to the position of the steel reinforced concrete beam 23 with respect to the girder 10.

Referring again to fig. 2, in some embodiments, the end of the first cross brace 22 intersects the end of the steel reinforced concrete beam 23 at the truss 10 side. Thus, the two structures can be combined to support each other, and the combined acting force resists the acting force of the truss 10 respectively and is stronger and stable.
