DETAILED DESCRIPTION

[0027] In the implementation manner of the present invention, the function of the arch support frame is the same as that of the existing truss, but the arch support frame occupies a smaller space. Therefore, the arch support frame provided in the implementation manner of the present invention can further reduce the influence of the truss structure on the indoor space, functional layout, building lighting and appearance of the building while meeting the support requirements, which is explained in detail below.

[0028] Figure 1 A schematic structural diagram of a truss structure provided in an embodiment of the present invention; Figure 2 Schematic diagram of the structure of the arch support frame 2 provided in the embodiment of the present invention. Figure 1 and Figure 2 As shown, the truss structure includes at least two columns 1 arranged at intervals, and adjacent columns 1 are connected by an arch support frame 2; both ends of the arch support frame 2 are respectively connected to the columns 1, and the top of the arch support frame 2 is not higher than the top of the column 1. In this embodiment, the top of the arch support frame 2 is flush with the top of the column 1, and two arch support frames 2 arranged side by side are arranged between two adjacent columns 1.

[0029] In the truss structure, the column 1 plays the role of the main support. The column 1 can be a square column, which includes four corner posts 11 arranged at the four corners and an intermediate post 12 located between adjacent corner posts 11. A plurality of transverse support rods 13 are connected to the corner posts 11 and the intermediate posts 12. The plurality of transverse support rods 13 are arranged at intervals along the height direction of the square column, and an oblique support rod 14 is arranged between adjacent transverse support rods 13. In the truss structure, only the column 1 is used as a structure connected to the ground, and the rest of the structures are arranged on the column 1.

[0030] like Figure 2As shown, the arch support frame 2 has the advantages of strong spanning ability and high force transmission efficiency; however, when transmitting vertical loads, a large thrust will be generated at the arch foot of the arch support frame 2. Therefore, in the embodiment of the present invention, the arch foot is connected to the column 1. After the arch foot is subjected to the load, it is transferred to the column 1. In this way, when the load is small, the column 1 itself offsets the load. When the load is large, a tension beam 3 can be set at the arch foot to connect the two arch feet through the tension beam 3. The arch support frame 2 is combined with the tension beam 3 to form a self-balancing arch structure system, and the tension beam 3 structure can eliminate part of the load. Among them, the tension beam 3 can also use a cable or other structure that can generate tension.

[0031] Figure 3 This is a schematic diagram of the structure of a plane truss provided in an embodiment of the present invention. Figure 1 and Figure 3 As shown, the truss structure also includes a first plane truss 4 and two second plane trusses 5, and the first plane truss 4 and the second plane trusses 5 are arranged at intervals along the height direction of the column 1; the two ends of the first plane truss 4 are respectively connected to the opposite surfaces of two adjacent columns 1, and the first plane truss 4 is located at the top of the column 1, and the first plane truss 4 is fixedly connected to the top of the arch support frame 2; the two second plane trusses 5 are respectively connected to the inner side and outer side of the two adjacent columns 1.

[0032] The first plane truss 4 and the second plane truss 5 have the advantages of large in-plane stiffness and small out-of-plane structural height. The first plane truss 4 and the second plane truss 5 are combined with the arch support frame 2, which can not only help the self-balancing arch structure system to establish out-of-plane stiffness, but also transfer the horizontal load borne in this area to the column 1 with greater stiffness.

[0033] In the embodiment of the present invention, the connection between the transverse support rod 13 and the angle rod 11 or the middle rod 12 is the installation position of the column 1, and the two ends of the arch support frame 2, the first plane truss 4 and the second plane truss 5 are connected to the installation position of the column 1. The strength of the installation position on the column 1 is higher, and a stronger force can be borne here.

[0034] Figure 4 A side view of a truss structure provided by an embodiment of the present invention. Figure 1 and Figure 4 As shown, the truss structure further includes a plurality of inclined rods 6, one end of the inclined rods 6 is connected to the end of the second plane truss 5 away from the column 1, and the other end is connected to the column 1 or the first plane truss 4. The inclined rods 6 can bear a certain load, and at the same time, transfer part of the load pressure to the second plane truss 5, and then transfer it to the column 1 through the second plane truss 5. In the embodiment of the present invention, by adding inclined rods 6 to the truss structure, the coverage of the truss structure can be further increased.

[0035] In an embodiment of the present invention, a building structure is further provided. The building structure includes the above-mentioned truss structure, and the truss structure is combined with the hoisting structure. Figure 5 A schematic diagram of a building structure provided for an embodiment of the present invention; Figure 6 A front view of a building structure provided by an embodiment of the present invention; Figure 7 A side view of a building structure provided by an embodiment of the present invention. Figures 5 to 7 As shown, the hoisting structure includes a hanging column 7, one end of which is connected to the first plane truss 4 or the second plane truss 5, and the other end is suspended. Multiple layers of floor beams 8 are arranged on the hanging column 7 at intervals along the height direction of the column 1. The floor beams 8 are horizontally arranged and perpendicular to the hanging column 7. Figure 8 Schematic diagram of the structure of the floor beam 8 provided in the embodiment of the present invention. Figure 8 As shown, the floor beam 8 includes a main beam 81 and a secondary beam 82 . The main beam 81 is connected with the suspension column 7 to form a frame structure. The main beams 81 are connected by intersecting secondary beams 82 .

[0036] The sling 7 is connected to the second plane truss 5. The sling 7 can be in the form of steel tie rods, cables, lattice or solid cross-section columns, steel plate combined slings 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 column 1. The building structure uses the floor beam 8 to transfer the horizontal force to the column 1. The position of the floor beam 8 can be in the same plane as the horizontal support rod 13 on the column 1.

[0037] 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 plane truss 4 and the second plane 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 plane truss 4 and the second plane truss 5, and then gradually installing the hoisting structure below. 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.

[0038] In the truss structure and building structure provided by the present invention, the truss uses an arched support frame 2, which has the advantages of strong spanning capacity and high force transmission efficiency. At the same time, compared with the existing truss structure, it occupies less space. Under the premise of meeting the support requirements, the arched support frame 2 further reduces the influence of the truss structure on the indoor space, functional layout, building lighting and appearance of the building.

[0039] 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.
