[0025] In the embodiment of the present invention, an arch support frame is used as the corner cantilever structure. On the premise of meeting the support requirements, the influence of the corner cantilever structure on the indoor space, functional layout, building lighting and appearance effect of the building can be further reduced, which will be specifically described below.

[0026] Figure 1 Structural schematic diagram of the corner cantilever structure provided by the embodiment of the present invention; Figure 2 Top view of the corner cantilever structure provided by the embodiment of the present invention. As Figure 1 and Figure 2 shown, the corner cantilever structure includes two corner columns 1, at least one arch support frame 2 and a first corner truss 4, wherein: the tops of the two corner columns 1 are connected by the first corner truss 4, and the two ends of the arch support frame 2 are respectively connected to the two corner columns 1, and the top of the arch support frame 2 is connected to the first corner truss 4.

[0027] Figure 3 Structural schematic diagram of the arch support frame in the corner cantilever structure provided by the embodiment of the present invention. As Figures 1 to 3As shown, in the corner cantilever structure, the corner column 1 plays a supporting role, and the cantilever structure is supported only by the corner column 1. The corner column 1 can be a square column, a circular column, etc. The arched support frame 2 has the advantages of strong spanning ability and high force transmission efficiency. However, when transmitting the vertical load, a large thrust will be generated at the arch feet of the arched support frame 2. Therefore, in the embodiment of the present invention, the arch feet are connected to the corner column 1. After the arch feet are subjected to the load, the load is transmitted to the corner column 1. When the load is small, the self-structure of the corner column 1 can offset the load. When the load is large, a first tie beam 3 can be provided at the arch feet for connection, so that the two arch feet are connected by the first tie beam 3. The arched support frame 2 and the first tie beam 3 form a self-balanced arch structure system, and the structure of the first tie beam 3 can eliminate part of the load. Among them, the first tie beam 3 can also be replaced by a cable or other structures with the same function.

[0028] As Figure 3 shown, due to the plane bending of the self-balanced arch structure system, a tipping trend opposite to the bending direction will be generated. In order to prevent the arched support frame 2 from tipping to one side and losing its bearing capacity, a second tie beam 9 is provided at the crown of the arched support frame 2. The first end of the second tie beam 9 is connected to the top of the arched support frame 2, and the second end is connected to the corner column 1. Preferably, the corner cantilever structure includes two second tie beams 9. The first ends of the two second tie beams 9 are both connected to the top of the arched support frame 2, and the second ends are respectively connected to different corner columns 1. The planes where the two second tie beams 9 are located are the same plane as the plane where the first corner truss 4 is located.

[0029] As Figures 1 to 3 shown, in the corner cantilever structure provided by the embodiment of the present invention, the first corner truss 4 includes an outer arched rod and an inner arched rod, and the outer arched rod and the inner arched rod are connected by a connecting rod. The corner column 1 includes an outer connection side and an inner connection side. The cantilever structure includes two arched support frames 2, namely an outer arched support frame and an inner arched support frame. The top of the outer arched support frame 2 is fixedly connected to the outer arched rod, and the two ends are respectively connected to the outer connection sides of the two corner columns. The top of the inner arched support frame is connected to the top of the inner arched rod, and the two ends are respectively connected to the inner connection sides of the corner columns. In the embodiment of the present invention, the first corner truss 4 is in an arched structure, with the inside being the inner side and the outside being the outer side within the arch. By adopting the support method on both the inner and outer sides, the support strength of the corner suspension structure can be further improved.

[0030] Figure 4 is a schematic structural diagram of the first corner truss and the second corner truss in the corner cantilever structure provided by the embodiment of the present invention. As Figure 1 、 Figure 2 and Figure 4As shown, the first corner truss 4 and the second corner truss 5 have a certain bending angle, and the height of the first corner truss 4 is higher than that of the second corner truss 5. In this embodiment, the second corner truss 5 is connected to both the inner side wall and the outer side wall of the corner column 1. The first corner truss 4 and the second corner truss 5 have the advantages of large in-plane stiffness and small out-of-plane structural height. The combination of the first corner truss 4 and the second corner truss 5 with the arched support frame 2 can not only help the self-balanced arch structure system establish out-of-plane stiffness, but also transfer the horizontal load borne in this area to the corner column 1 with greater stiffness.

[0031] As Figure 1 and Figure 2 shown, the truss structure further includes a plurality of diagonal tension rods 6. One end of the diagonal tension rod 6 is connected to the end of the second corner truss 5 far from the corner column 1, and the other end is connected to the corner column 1 or the first corner truss 4. The diagonal tension rod 6 can bear a certain load by itself. At the same time, it also transfers part of the load pressure to the second corner truss 5, and uses the second corner truss 5 to transfer it to the corner column 1. In the embodiment of the present invention, by adding the diagonal tension rod 6 to the corner suspension structure, the coverage range of the corner suspension structure can be further increased.

[0032] In the embodiment of the present invention, a building structure is further provided. The building structure includes the above-mentioned corner suspension structure, and the corner suspension structure is combined with the hoisting structure. Figure 5 is the structural schematic diagram of the building structure provided by the embodiment of the present invention; Figure 6 is the front view of the building structure provided by the embodiment of the present invention. As Figure 5 and Figure 6 shown, the hoisting structure includes a suspension column 7. One end of the suspension column 7 is connected to the first corner truss 4 or the second corner truss 5, and the other end is suspended. A plurality of floor beams 8 are arranged at intervals along the height direction of the corner column 1 on the suspension column 7. The floor beams 8 are horizontally arranged and are perpendicular to the suspension column 7. Figure 7 is the structural schematic diagram of the floor beam provided by the embodiment of the present invention. As Figure 7 shown, the floor beam 8 includes a main beam 81 and a secondary beam 82. The main beam 81 is connected to the suspension column 7 to form a frame structure; the main beams 81 are connected by intersecting secondary beams 82.

[0033] The sling 7 is connected to the second corner truss 5. The sling 7 can be in the form of a steel tie rod, a cable, a lattice or solid cross-section column, a steel plate combined sling 7, etc. Since the sling 7 only bears tension (vertical direction), it does not have the problem of instability, so the material strength utilization rate is higher. Compared with conventional compression structure columns, the sling 7 can adopt a smaller cross-section to obtain a more slender shape, so that the space occupied by the indoor structural columns of the building is smaller, and more usable area and a more transparent architectural effect are obtained. The floor beam 8 is arranged horizontally and hung on the sling 7. The floor beam 8 is also connected to the corner column 1. The building structure uses the floor beam 8 to transmit the horizontal force to the corner column 1.

[0034] In the building structure provided by the embodiment of the present invention, an independent rectangular support structure is formed by the arch support frame 2, the first corner truss 4 and the second corner truss 5, and the support structure can bear the vertical and horizontal loads of the hoisting structure. When performing on-site construction, the reverse method can be adopted, that is, the construction is carried out step by step from top to bottom, first completing the installation of the arch support frame 2, the first corner truss 4 and the second corner truss 5, and then gradually installing the hoisting structure below them. During the specific construction, various methods such as lifting, jacking, sliding, and in-situ assembly can be adopted; or the sequential method can be used for construction, and a full-hall support or a tire frame support is set according to the conventional construction method, and installed layer by layer from bottom to top.

[0035] In the corner cantilever structure and building structure provided by the present invention, the corner cantilever structure uses an arch support frame 2, which has the advantages of strong spanning capacity and high force transmission efficiency. At the same time, compared with the existing corner cantilever structure, the arch support frame occupies less space. Under the premise of meeting the support requirements, the arch support frame 2 further reduces the influence of the truss structure on the indoor space, functional layout, building lighting and appearance of the building.

[0036] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions may occur depending on design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
