The awning structure is an important component of a stadium, not only meets the using function of a building, but also is an important carrier for forming the building shape and building the building originality. Commonly used stadium awning structure systems are divided into two major categories, namely rigid (space or plane cantilever truss structures and arch truss structures) and flexible (integral tensioning structures and mast diagonal structures).

The rigid system of the cantilever truss in a single space or plane is adopted, the length of the cantilever is not too large due to the limitation of the stress form characteristics of the truss, and the building shape is relatively simple. The conventional awning of the cantilever truss solves the problems of bearing capacity and rigidity only through root bending resistance, belongs to a typical cantilever beam stress mode, and the control on the deflection depends on a root bending resistance mechanism and the rigidity distribution of the cantilever truss. According to the relation between the awning supporting point and the lower concrete stand, the awning is divided into a single-fulcrum type and a double-fulcrum type, the single-fulcrum type is that the awning is separated from the stand, the single point is rigidly connected to the ground or a platform, the safety degree is low, and the overhanging length can reach 30 m. The double-pivot type is that a lower stand structure or the ground and the like provide two pivots for the awning, so that the overturn-resisting force arm is increased, the stress tends to be reasonable, and the cantilever length can reach 40 m. The single arched rigid system, the flexible integral tensioning system and the mast cable-stayed system are adopted, the requirement on building modeling is high, the arched system needs large height loss, the mast needs a special tensioning space, the integral tensioning system roof is relatively gentle in requirement, although the advantages of materials are fully exerted, the cantilever length can reach 40-60 m, and the flexible and changeable building modeling requirement cannot be met.

Therefore, how to satisfy the performance requirement of the architectural modeling on the awning structure while increasing the overhanging height and the span becomes a technical problem to be solved in the field.

According to another aspect of the present application, there is provided a building, wherein the building comprises the awning cantilever structure of the present application.

The torsional trusses 110 form a cross support structure by torsional crossing, thereby taking up vertical loads and providing a primary side force resistance effect, increasing the span of the cantilever. The roofing exit suspension truss 200 effectively increases overall vertical stiffness, cantilever height, and effectively transfers force through the cross-twist truss sections 100 and the support columns 300. Consequently, the structure of encorbelmenting of awning of this application can satisfy and guarantee holistic stability when more encorbelment height, span.

Specifically, the spatial crossed rhombic grids are formed by twisting, and each twisting truss 110 has a cross supporting effect, so that vertical load can be borne, a lateral force resisting effect can be provided, and the spatial performance of the awning cantilever structure is enhanced. And, when promoting overall stability, can increase overhanging height and span.

The torsional trusses 110 may be arranged in segments for ease of arrangement in a cross-twisted fashion. Specifically, as shown in fig. 3, the torsion truss 110 may include a floor cross section 111 and an overhanging cross section 112 connected above the floor cross section 111, the floor cross section 111 forms a diamond grid of the floor cross, the overhanging cross section 112 forms a diamond grid of the overhanging cross, and the roof-out suspension truss 200 is disposed on the overhanging cross section 112. Wherein, the overhanging span of the roof-out suspension truss 200 can be consistent with the overhanging end span of the correspondingly connected torsion truss 110. For example, the maximum span of the cantilevered end of the lattice 110 may be up to 50m, and the span of the cantilevered end of the roof suspension truss 200 may also be up to 50 m.

In order to increase the overall stability of the cross-twisted truss structure 100, the overhanging cross-section 112 includes a first portion 112a connecting the landing cross-section 111 and a second portion 112b extending from the first portion 112a in an overhanging manner, the first portion 112a and the second portion 112b are demarcated by outer ring intersections of overhanging crossed rhombus meshes, and the cross-twisted truss structure 100 includes an outer ring truss 120 connecting the transverse intersections of the rhombus meshes of the landing cross, an intermediate ring truss 130 connecting the outer ring transverse intersections of the rhombus meshes of the overhanging cross, and an inner ring truss 140 connecting the inner ring transverse intersections of the rhombus meshes. Thus, the torsion truss 110 can be spatially hooped by the outer ring truss 120, the intermediate ring truss 130, and the inner ring truss 140, and the overall stability of the cross torsion truss portion 100 can be ensured.

Wherein, the out-of-roof suspension truss 200 can increase the cantilever height on the one hand, and effectively increase the vertical rigidity on the other hand. Specifically, the upper chord 210 is under tension, the lower chord 220 is under compression, and the axial force of the web member 230 is directly transmitted to the cross torsion truss portion 100, so that the force transmission is clear, safe and reliable.

The out-roof suspension truss 200 may be arranged in sections for ease of installation. Specifically, as shown in fig. 10, the roof-out suspension truss 200 includes a first section 200a extending from the outer ring truss 120 to the intermediate ring truss 130 and a second section 200b extending from the intermediate ring truss 130 to the inner ring truss 140, and the roof-out suspension truss 200 reaches a maximum arching height at the intermediate ring truss 130.

For added stability, the unitary shroud 400 may span within 20m and the shroud 400 may be configured as a planar truss to transfer vertical and wind loads.

According to needs, the awning overhanging structure of the application can be provided with a corresponding decorative structure. For example, the awning cantilever structure may include decorative grills disposed on both sides of the out-roof suspension truss 200. The decorative grid is only used for decoration and does not bear acting force, and the decorative grid can be designed into a triangular space truss by adopting square steel pipes according to pull rods, so that a structure which is arched upwards from the roof-out suspension truss 200 is formed.
