DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] In the present invention, the directions or positional relationships indicated by the terms "upper" and "lower" are based on the directions or positional relationships shown in the accompanying drawings. These terms are mainly used to better describe the present invention and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific direction, or to be constructed and operated in a specific direction.

[0034] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in this utility model can be understood according to specific circumstances.

[0035] In addition, the terms "disposed", "provided with", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0036] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0037] When the design of the cross-section connection node where multiple box-shaped steel pipes meet is usually faced with problems such as complex node connection, indirect force transmission of components and difficult design. In particular, in the spatial grid structure, there is usually one component as the main component, and other components are connected to the main component to form a connection node that meets. In the prior art, when designing the node connection, the connection is usually made by intersecting welding, that is, the main component is kept through, and other components are used as intersecting components. The intersecting components are cut along the intersection line (intersecting line) with the main component and then welded to the main component. In the case where multiple box-shaped components come from different planes and meet, for example, the box-shaped components come from the first plane and the second plane respectively, and the two planes meet at a certain angle. When the connection design of the components is carried out by the prior art, the flange of the box-shaped component will be welded to the side wall of the main component, and the internal force of the flange can only be transmitted to the main component by the weld through the out-of-plane transmission. However, this out-of-plane force transmission method of the component is an unreliable and indirect force transmission method, which will cause local stress concentration and local buckling, forming a weak part.

[0038] Based on this, the utility model provides a connection node of a spatial grid structure and a spatial grid structure, wherein a first component is extended along a first plane, and a second component is extended along a second plane, and the second plane is arranged at an angle to the first plane, and the cross-sectional shapes of the first component and the second component are both box-shaped. A force transmission component is arranged between the first component and the second component, and the cross-sectional shape of the force transmission component is a trapezoid, and the trapezoid has an upper base, a lower base, a first waist edge and a second waist edge, the first waist edge extends along the normal of the first plane, and the second waist edge extends along the normal of the second plane, the first component is connected to the first waist edge, and the second component is connected to the second waist edge. The utility model utilizes a force transmission component with a trapezoidal cross section to provide a fixed connection plane for box-shaped components from planes in two directions, so that the components are located in the same plane to establish a connection with the force transmission component, avoiding out-of-plane force transmission between components, making the connection between the components and the force transmission component smooth, and the force transmission is more direct, thereby avoiding local stress concentration and improving the reliability of the connection node.

[0039] The technical solution of the utility model will be further described below in conjunction with embodiments and drawings.

[0040] Please also read Figure 1 and Figure 2The embodiment of the utility model discloses a connection node 100 of a space grid structure 200, the connection node 100 comprises a first member 10, a second member 20 and a force transmission member 30, the first member 10 is extended along a first plane P1, and the cross-sectional shape of the first member 10 is box-shaped. The second member 20 is extended along a second plane P2, the second plane P2 is arranged at an angle with the first plane P1, and the cross-sectional shape of the second member 20 is box-shaped. The force transmission member 30 is located between the first member 10 and the second member 20, and the cross-sectional shape of the force transmission member 30 is a trapezoid 301, the trapezoid 301 has an upper base 301a, a lower base 301b, a first waist edge 301c and a second waist edge 301d, the first waist edge 301c extends along the normal direction of the first plane P1, the second waist edge 301d extends along the normal direction of the second plane P2, the first member 10 is connected to the first waist edge 301c, and the second member 20 is connected to the second waist edge 301d.

[0041] The first component 10 of the utility model is connected to the first waist edge 301c, and the second component 20 is connected to the second waist edge 301d, and the first waist edge 301c and the second waist edge 301d extend along the normal of the first plane P1 and the second plane P2 respectively. The force transmission component 30 with a trapezoidal cross-section 301 is used to provide a fixed connection plane for the box-type components from the two planes, so that the components are located in the same plane and connected to the force transmission component 30 to achieve in-plane force transmission, avoiding out-of-plane force transmission between the components, making the connection between the component and the force transmission component 30 smooth and the force transmission more direct, thereby avoiding local stress concentration and improving the reliability of the connection node 100.

[0042] In addition, compared with the method of intersecting welding, the connection node 100 of the present invention eliminates the design work of solving the intersection line and the processing work of cutting components along the intersection line, so that the connection node 100 of the components of the two planes adopts a unified design and processing method, which simplifies the design and processing of the connection node 100 as a whole, thereby improving the convenience of construction.

[0043] Optionally, the trapezoid 301 may be an isosceles trapezoid. Using an isosceles trapezoidal cross section as the cross section of the force transmission member 30 can facilitate the processing of the force transmission member 30 on the one hand, and on the other hand, ensure the consistency of force transmission between the first member 10 and the second member 20, so that the connection between the members is more coherent and smooth, thereby making the force transmission more direct and the force transmission effect better.

[0044] In some embodiments, see Figure 2The force transmission member 30 includes an upper flange 31, a lower flange 32, a first web 33 and a second web 34. The upper flange 31 and the lower flange 32 are arranged opposite to each other. The first web 33 and the second web 34 are arranged at intervals and connected between the upper flange 31 and the lower flange 32. The upper flange 31 and the lower flange 32 respectively form an upper bottom 301a and a lower bottom 301b of the trapezoid 301. The force transmission member 30 has two webs connected between the upper flange 31 and the lower flange 32, that is, the force transmission member 30 can be a box-type member. In the space grid structure 200 with a large span, as the main through-going main member, it has higher strength and rigidity.

[0045] As can be seen from the above, the cross-sectional shape of the first component 10 and the second component 20 is a box-shaped one, for example, a box-shaped steel pipe, that is, the cross-sectional shape of the first component 10 and the second component 20 can be a rectangle, then the first component 10 and the second component 20 also have two flanges and two webs, and the upper and lower flanges and the two webs together enclose the aforementioned rectangular cross-sectional shape. The flange and web of the first component 10 are both connected to the first waist edge 301c, and the flange and web of the second component 20 are both connected to the second waist edge 301d.

[0046] In order to enable the flanges of the first component 10 and the second component 20 to be directly connected to the flanges of the force transmission component 30, the force transmission is more direct. Optionally, the angle between the second plane P2 and the first plane P1 is the first angle, and the upper flange 31 and the lower flange 32 are respectively extended and arranged along the direction perpendicular to the angle bisector O of the first angle. In this way, the flange of the first component 10 can be directly connected to the flange of the force transmission component 30, and the flange and the web of the first component 10 are both located in the first plane P1 and connected to the force transmission component 30, so that the connection between the first component 10 and the force transmission component 30 is more coherent, and the internal force of the first component 10 can be directly transmitted. Similarly, the flange of the second component 20 can also be directly connected to the flange of the force transmission component 30, and the flange and the web of the second component 20 are both located in the second plane P2 and connected to the force transmission component 30, so that the connection between the second component 20 and the force transmission component 30 is more coherent, and the internal force of the second component 20 can be directly transmitted. As a result, the first component 10, the second component 20 and the force transmission component 30 from two different planes are smoothly connected, and the force transmission is direct.

[0047] In a possible implementation, the first web 33 and the second web 34 are both arranged in a direction parallel to the angle bisector O. That is, the cross section of the force transmission member 30 is not a completely closed space, and the outer contour of the cross section of the force transmission member 30 is a trapezoid 301, and the first web 33 and the second web 34, and part of the upper flange 31 and the lower flange 32 form a rectangle. In this way, the flange of the force transmission member 30 can be made wide and have a large lateral stiffness, and has a stronger bending resistance after being connected to the first member 10 and the second member 20 respectively.

[0048] Based on the above-mentioned first web 33 and second web 34 being arranged in a direction parallel to the angle bisector O, in order to ensure that the first member 10 and the second member 20 can be reliably connected to the force transmission member 30, see Figure 2 and Figure 3 , the connection node 100 may also include a first rib plate 40 and a second rib plate 50, the first rib plate 40 is connected to the first member 10 and the first web plate 33, the second rib plate 50 is connected to the second member 20 and the second web plate 34, and the first rib plate 40 forms the first waist side 301c of the trapezoid 301, and the second rib plate 50 forms the second waist side 301d of the trapezoid 301. That is, the first member 10 is connected to the force transmission member 30 through the first rib plate 40, and the second member 20 is connected to the force transmission member 30 through the second rib plate 50. In this way, the connection between the first member 10 and the force transmission member 30 is not only connected by the flange, but the web of the first member 10 can be connected to the first rib plate 40, so as to strengthen the connection strength between the first member 10 and the force transmission member 30. Similarly, the connection between the second member 20 and the force transmission member 30 is not only connected by the flange, but the web of the second member 20 can be connected to the second rib plate 50, so as to strengthen the connection strength between the second member 20 and the force transmission member 30. Thereby, the internal force transmission at the connection node 100 can be made more reliable.

[0049] Optionally, the first member 10 may be a box-shaped steel pipe having two webs, and when the first member 10 and the force transmission member 30 are connected, two first ribs 40 may be provided, and the two first ribs 40 respectively correspond to the two webs of the first member 10, that is, the two webs of the first member 10 are connected to the force transmission member 30 through the two first ribs 40. Similarly, the second member 20 may be provided in the same manner, which will not be described in detail herein.

[0050] It is understandable that, with the above-mentioned web design, an angle is formed between the web and the flange. In order to reasonably arrange the ribs, optionally, the first rib 40 is located between the upper flange 31, the lower flange 32 and the first web 33, and is connected to the three by fillet welding, and the second rib 50 is located between the upper flange 31, the lower flange 32 and the second web 34, and is connected to the three by fillet welding. In this way, the two-side space formed by the flange and the web of the force transmission component 30 can be reasonably utilized. For the ribs arranged under the space, it is more reasonable to adopt the connection method of fillet welds, and the fillet weld connection fuses a part of the connected component at the welding point, forming a more solid connection point, so that the connection between the ribs and the force transmission component 30 has higher reliability and stability.

[0051] In another possible implementation, see Figure 4 and Figure 5, the first web 33 and the second web 34 respectively form the first waist 301c and the second waist 301d of the trapezoid 301. That is, the cross section of the force transmission member 30 forms a completely closed space, and the shape of the space is a trapezoid 301. Such a closed cross-section design can effectively balance the internal forces of the components transmitted in different directions, and ensure the stability and safety of the entire connection node 100. In addition, the force transmission member 30 has better processing performance and welding performance, which can meet complex connection requirements. For example, the force transmission member 30 connects more components to form a more complex connection node 100.

[0052] When the first web 33 and the second web 34 respectively form the first waist 301c and the second waist 301d of the trapezoid 301, no ribs are required for connection, and the first component 10 and the second component 20 can be directly connected to the force transmission component 30. Specifically, Figure 5 As shown, the flange of the first member 10 can be directly connected to the flange of the force transmission member 30, and the web of the first member 10 can be connected to the first web 33. Similarly, the flange of the second member 20 can be directly connected to the flange of the force transmission member 30, and the web of the second member 20 can be connected to the second web 34.

[0053] In some embodiments, the first component 10 and the force transmission component 30, and the second component 20 and the force transmission component 30 are welded and / or bolted. Exemplarily, the flange of the first component 10 and the flange of the force transmission component 30, and the web of the first component 10 and the web of the force transmission component 30 can be directly connected by a butt weld connection, which is a strong connection method, to ensure the stability and reliability of the connection. When the first component 10 is connected to the force transmission component 30 through the first rib 40, a butt weld connection method can also be adopted. In this case, the web of the first component 10 and the first rib 40 need to be welded. Of course, in another example, the web of the first component 10 can be bolted to the first rib 40. In this case, the on-site welding work can be reduced, thereby simplifying the on-site installation work of the connection node 100. At the same time, the bolts can be used as a way to position and temporarily fix between components, which is more convenient for on-site construction.

[0054] Optionally, the number of the first component 10 and the second component 20 can be one, that is, the connection node 100 can be formed by the intersection of three components. Of course, the number of the first component 10 and the second component 20 can also be multiple, that is, the number of the first components 10 located in the first plane P1 and the number of the second components 20 located in the second plane P2 are not limited to one. For example, the number of the first component 10 and the second component 20 can be two, three, etc. These components and the force transmission component 30 converge to form the connection node 100. The connection method is the same as the above embodiment, and the specific number is not limited in the embodiment of the utility model.

[0055] For example, see Figure 6 and Figure 7 , the number of first components 10 from the first plane P1 is three, and these three components extend in different directions in the first plane P1, the number of second components from the second plane P2 is two, and these two components extend in different directions in the second plane P2, and the connection node 100 can be formed by the intersection of six components. It can be understood that the cross-sections of the components from the first plane P1 and the second plane P2 can both be rectangular, but the sizes of the rectangles can be different. Of course, rectangles of the same size can also be used, and the specific setting can be based on actual needs. The way in which multiple first components 10 and multiple second components 20 converge with the force transmission component 30 to form a connection node 100 is the same as the connection node 100 described in the above embodiment, and has the same or similar beneficial effects. For details, please refer to the description in the above embodiment, and the embodiments of the present application will not be repeated here.

[0056] The utility model discloses a space grid structure 200, see Figure 8 , including a plurality of connection nodes 100 as described above. Specifically, with the force transmission component 30 as the main component, a plurality of first components 10 and second components 20 intersect with the force transmission component 30, and extend in the first plane P1 and the second plane P2 respectively to form a spatial grid structure 200. It can be understood that the components in the first plane P1 and the second plane P2 form a spatial structure 200 with a folded surface, thereby making the force transmission at the connection node 100 more reliable and also facilitating the spatial grid structure 200 to present a unique shape. The spatial grid structure 200 having the above-mentioned connection node 100 also has other beneficial effects that are the same or similar to the connection node 100 in the above-mentioned embodiment, which can be specifically referred to the description in the above-mentioned embodiment, and the embodiments of the utility model will not be repeated here.

In summary, the content of this specification should not be understood as a limitation on the utility model.
