[0028] The technical solutions of this application will be further described below in conjunction with embodiments and the accompanying drawings.

[0029] Please refer to Figure 1 and Figure 2 , in a first aspect, an embodiment of this application provides a support truss structure 10, including a chord member assembly 11 and a connection assembly 12; the chord member assembly 11 includes an upper chord 14 and a lower chord 15 arranged oppositely; the connection assembly 12 includes a plurality of connecting rods, and the plurality of connecting rods are used to connect the upper chord 14 and the lower chord 15 to form a basic support truss structure 10.

[0030] In some embodiments, the upper chord 14 is formed by sequentially connecting a plurality of spliced members 111, and the lower chord 15 is also formed by sequentially connecting a plurality of spliced members 111. The spliced member 111 includes a first member 1112 and a second member 1113. The first member 1112 is fixedly connected to the second member 1113, and the cross-sectional area of the first member 1112 is smaller than that of the second member 1113. Compared with using a continuous steel member with a relatively large cross-sectional area as the chord in the current industry, such a spliced member 111 not only reduces the weight of the support truss structure 10 but also saves material costs. In addition, compared with using a chord with a continuously varying cross-sectional area, the present application does not require additional customization of a chord with a variable cross-sectional area. Only ready-made members with different cross-sectional areas need to be selected and spliced according to actual requirements for use. The manufacturing and processing method is relatively simple, with low costs and strong flexibility.

[0031] In some embodiments, the distance between the connection node of the upper chord 14 and the connecting member and the connection point of the first member 1112 and the second member 1113 is 100 mm to 500 mm, and the distance between the connection node of the lower chord 15 and the connecting member and the connection point of the first member 1112 and the second member 1113 is 100 mm to 500 mm. This can optimize the force distribution, reduce stress concentration, improve the overall stability and load-bearing capacity of the spliced member 111, ensure the load-bearing capacity of the spliced member 111 while saving material costs, and is beneficial to improving the structural stability and structural safety of the support truss structure 10 and extending the service life of the support truss structure 10.

[0032] In some embodiments, the second member 1113 includes a member body 11132 and a transition plate 11133. The transition plate 11133 is disposed at the end of the member body 11132; the transition plate 11133 is arranged in a plate-like structure, and the thickness of the transition plate 11133 is 6 mm to 20 mm. One end of the first member 1112 close to the second member 1113 abuts against the transition plate 11133 and is fixedly connected to the transition plate 11133, thereby realizing the fixed connection between the first member 1112 and the second member 1113.

[0033] In some embodiments, the transition plate 11133 and the member body 11132 are integrally formed, which is beneficial to strengthening the structural strength of the second member 1113, reducing the number of parts, and facilitating the on-site assembly of the support truss structure 10. In some embodiments, the transition plate 11133 is full-welded to the first member 1112. The transition plate 11133 provides an additional support and connection surface, which is beneficial to the stable connection between the first member 1112 and the second member 1113. In other embodiments, the transition plate 11133 can also be fixedly connected to the first member by, for example, mechanical bolt connection, riveting, or other welding methods, etc., and is not limited thereto.

[0034] In this embodiment, the cross-sectional area of the transition plate 11133 has the same shape and size as that of the rod main body 11132. In other embodiments, the shape of the cross-sectional area of the transition plate 11133 and that of the rod main body 11132 may be different, as long as the cross-sectional area of the transition plate 11133 is larger than that of the rod main body 11132 and the transition plate 11133 can cover the end of the rod main body 11132.

[0035] In some embodiments, the connection assembly 12 includes a plurality of first connecting rod members 121 and a plurality of second connecting rod members 122; the plurality of first connecting rod members 121 are arranged longitudinally and are spaced along the length directions of the upper chord 14 and the lower chord 15; the second connecting rod members 122 are arranged obliquely relative to the first connecting rod members 121 and are disposed on the sides of the first connecting rod members 121. In some embodiments, the included angle formed by the second connecting rod member 122 and the upper chord 14 or the lower chord 15 is 30°-45°.

[0036] In this embodiment, one first connecting rod member 121 and two second connecting rod members 122 disposed at the upper chord 14 or the lower chord 15 form a connection node structure; and the plurality of first connecting rod members 121, second connecting rod members 122, upper chord 14 and lower chord 15 together form a plurality of triangular-like grid units, and such triangular-like grid units can improve the stiffness and stability of the structure. In other embodiments, the connection node structure at the upper chord 14 or the lower chord 15 may also be composed of one first connecting rod member 121 and three or four second connecting rod members 122, and thus it is not limited thereto.

[0037] In this embodiment, one end of the first connecting rod member 121 is fully welded to the upper chord 14, and the other end of the first connecting rod member 121 is fully welded to the lower chord 15; one end of the second connecting rod member 122 is fully welded to the upper chord 14, and the other end of the second connecting rod member 122 is fully welded to the lower chord 15; which is beneficial to enhancing the connection strength of the support truss structure 10. In other embodiments, the first connecting rod member 121 and the second connecting rod member 122 may be fixedly connected to the upper chord 14 and the lower chord 15 by other welding methods, and thus it is not limited thereto.

[0038] In some embodiments, the support truss structure 10 further includes a strengthening assembly 13; the strengthening assembly 13 includes a plurality of first strengthening members (not shown in the figure) and a plurality of second strengthening members 131. The first strengthening members are disposed on the side of the upper chord 14 facing the lower chord 15, and the plurality of first strengthening members are sequentially and spacedly disposed on the upper chord 14. The second strengthening members 131 are disposed on the side of the lower chord 15 facing the upper chord 14, and the plurality of second strengthening members 131 are sequentially and spacedly disposed on the lower chord 15. One end of the connecting member close to the first strengthening member is fixedly connected to the first strengthening member, and one end of the connecting member close to the second strengthening member 131 is fixedly connected to the second strengthening member 131. The first strengthening member can disperse the stress at the connection node of the upper chord 14 where the connecting member is disposed, reduce stress concentration, reduce the risk of deformation of the upper chord 14 caused by excessive local stress on the upper chord 14, and improve the connection strength. The second strengthening member 131 can disperse the stress at the connection node of the lower chord 15 where the connecting member is disposed, reduce stress concentration, reduce the risk of deformation of the lower chord 15 caused by excessive local stress on the lower chord 15, and improve the connection strength, thereby improving the overall structural stability and structural safety of the support truss structure 10.

[0039] In this embodiment, the first strengthening member is full-welded to the upper chord 14, and the second strengthening member 131 is full-welded to the lower chord 15, which is beneficial to improving the connection strength of the support truss structure 10. In other embodiments, the first strengthening member can also be fixedly connected to the upper chord 14 by, for example, mechanical bolt connection, riveting or other welding methods, and the second strengthening member 131 can also be fixedly connected to the lower chord 15 by, for example, mechanical bolt connection, riveting or other welding methods, so it is not limited thereto.

[0040] As mentioned above, the connection assembly 12 includes a plurality of first connecting members 121 and a plurality of second connecting members 122, wherein the second connecting members 122 are disposed obliquely relative to the first connecting members 121. In some embodiments, the dimension of the portion of the first strengthening member outside the second connecting member 122 is 20 mm to 200 mm, and the dimension of the portion of the second strengthening member 131 outside the second connecting member 122 is 20 mm to 200 mm. This can avoid the problem that the welding area is too close to the edges of the first strengthening member and the second strengthening member 131 when the second connecting member 122 is welded to the first strengthening member and the second strengthening member 131, resulting in poor welding quality and insufficient connection strength. It helps to ensure that the stress distribution at the welded joint is more uniform, thereby improving the bearing capacity and strength of the welded joint, preventing local stress concentration, and enhancing the overall structural stability of the support truss structure 10. In addition, it helps to increase the operating space during the construction process, enables the welding work to proceed more smoothly, reduces construction difficulties and operation risks.

[0041] In some embodiments, the upper chord 14, the lower chord 15, the first reinforcing member, and the second reinforcing member 131 are all made of stainless steel. Using members of the same material can avoid stress concentration or deformation problems caused by differences in the thermal expansion coefficients between different materials, and improve the welding quality.

[0042] In some embodiments, the upper chord 14, the lower chord 15, the first connecting member 121, and the second connecting member 122 are all square tubes; in other embodiments, the upper chord 14, the lower chord 15, the first connecting member 121, and the second connecting member 122 can also be set as round tubes, so this is not limited thereto.

[0043] The support truss structure 10 provided in this application reduces the materials required for the upper chord 14 and the lower chord 15 and reduces the material cost by setting the splicing member 111 to include a first member 1112 and a second member 1113 that are fixedly connected, and the cross-sectional area of the first member 1112 is smaller than the cross-sectional area of the second member 1113. And a first reinforcing member is added at the connection node between the upper chord 14 and the connecting member, and a second reinforcing member 131 is added at the connection node with the connecting member, so as to disperse the stress at the connection nodes of the upper chord 14 and the lower chord 15, and evenly distribute the connecting member load to the upper chord 14 and the lower chord 15, avoiding local overstress and deformation of the upper chord 14 and the lower chord 15, and improving the overall structural safety of the support truss structure 10.

[0044] In a second aspect, please refer to Figure 2 , embodiments of the present application further provide a building, which includes but is not limited to a factory building, a stadium, a large shopping mall, and a high-speed railway station, etc. In some embodiments, the building includes support columns 20, a plurality of purlins 30, a roof structure 40, and the support truss structure 10 as described above; the support truss structure 10 is fixedly arranged on the upper part of the support columns 20, and the roof structure 40 is fixedly arranged on the top of the support truss structure 10 through a plurality of purlins 30. Since the support truss structure 10 has high structural safety, a building with the support truss structure 10 provided in this application can achieve a larger span.

[0045] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0046] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
