DETAILED DESCRIPTION
[0023] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the specific implementation modes of the present invention will be clearly and completely described below.
[0024] The present application discloses a tube truss 100 and an assembly method thereof, which includes a tube truss chord 11, a web member 13, a reinforcing rod 14 and a fixing rod 15. The tube truss chord 11 includes at least two tube truss chords, the two tube truss chords 11 are crossed and arranged in the horizontal direction, a reinforcing member 12 is arranged at the intersection of the two tube truss chords 11, and a plurality of inwardly recessed sockets are arranged on the reinforcing member 12. The two tube truss chords 11 are crossed and a reinforcing member 12 is arranged at the intersection to fix the two tube truss chords 11, and such an arrangement forms the basic framework of the tube truss 100. The web members 13 include at least two, and plugs 131 corresponding to the sockets are provided at both ends of the web members 13. The web members 13 are arranged in the vertical direction and extend into the reinforcement member 12 and are inserted into the sockets of the tube truss chord 11 through the plugs 131. Each of the at least two web members 13 forms a triangular pyramid structure with both sides of the crossed tube truss chord 11, and at least two web members 13 are inserted into the sockets to form a triangular pyramid with two vertices connected. One end of the reinforcing rod 14 is fixedly connected to the web member 13, and the other end of the reinforcing rod 14 is fixedly connected to another adjacent web member 13. The web member 13 is fixed by the reinforcing rod 14. The reinforcing rod 14 includes a plurality of web members. When constructing the web members 13, the number of reinforcing rods 14 used can be appropriately selected according to the use conditions and scenes. The reinforcing rod 14 and the web members 13 on both sides form a triangular structure to support the tube truss 100 and prevent the tube truss 100 from deforming. One end of the fixing rod 15 is provided with a chord rod collar 151 of the same shape as the tube truss chord rod 11, and the other end of the fixing rod 15 is provided with a reinforcing collar 152 of the same shape as the reinforcing rod 14. The chord rod collar 151 includes a left chord rod collar 1511 and a right chord rod collar 1512. The left chord rod collar 1511 is fixedly connected to the fixing rod 15. Both sides of the left chord rod collar 1511 and the right chord rod collar 1512 are respectively provided with penetrating chord rod collar 151 through holes. The fixing bolt passes through the chord rod collar 151 through holes to fix the left chord rod collar 151. 511 and the right chord sleeve 1512, the reinforcement sleeve 152 includes a left reinforcement sleeve 1521 and a right reinforcement sleeve 1522, the left reinforcement sleeve 1521 is fixedly connected to the fixing rod 15, and penetrating reinforcement sleeve 152 through holes are respectively provided on both sides of the left reinforcement sleeve 1521 and the right reinforcement sleeve 1522, and the fixing bolts pass through the through holes of the reinforcement sleeve 152 to fix the left reinforcement sleeve 1521 and the right reinforcement sleeve 1522, the chord sleeve 151 is fixed to the tube truss chord 11, and the reinforcement sleeve 152 is fixed to the reinforcement rod 14.The web member 13 is inserted into the socket of the tube truss chord 11 through the plug 131. However, when the tube truss 100 is installed and used, the web member 13 may fall off from the tube truss chord 11. The present application uses a fixing rod 15 to detachably connect the reinforcing rod 14 that fixes two adjacent web members 13 to the tube truss chord 11. On the one hand, it can prevent the web member 13 from falling off from the tube truss chord 11, and on the other hand, it can further increase the overall support effect of the tube truss 100 and increase the support capacity of the tube truss 100. The tube truss 100 of the present application is formed by the basic frame formed by the crossed tube truss chord 11 and the reinforcement 12, plus the triangular cone structure formed by the web member 13, and the triangular support formed by the reinforcing rod 14, which together constitute an extremely stable structural system. This design can effectively disperse the load and improve the overall rigidity and stability of the tube truss 100 structure. The use of a quick connection method between the plug 131 and the socket makes on-site installation simple and quick. Through the connection of the chord ring 151 and the reinforcement ring 152 on the fixing rod 15 and the fixing bolts, a detachable connection between the components is achieved, which is convenient for reuse and maintenance. The design of the tube truss 100 allows the selection of a suitable number of reinforcement rods 14 according to actual use conditions and scenarios, so that the tube truss 100 can be flexibly applied to construction projects of different scales and purposes to meet diverse needs. The design of the fixing rod 15 not only prevents the risk of the web member 13 falling off the tube truss chord 11, but also enhances the supporting capacity of the entire tube truss 100, ensuring the reliability and safety of the structure when subjected to external loads. The present application can completely avoid the use of welding for connection, which can prevent the chord from moving closer to the direction of weld contraction and avoid the reduction in the processing accuracy of the tube truss 100 due to welding.
[0025] As an embodiment, the angle α between at least two intersecting tube truss chords 11 is greater than or equal to 50° and less than or equal to 70°. The angle between the intersecting tube truss chords 11 is the most stable when it is in a triangular shape during assembly, and the fixing effect of an equilateral triangle is the best among the triangles. In the present application, the angle α between the two intersecting tube truss chords 11 is set to be greater than or equal to 50° and less than or equal to 70°, so that the triangle between the intersecting tube truss chords 11 is closest to an equilateral triangle when the tube truss 100 is finally assembled. Preferably, the angle α between the two intersecting tube truss chords 11 is 60°. There are at least six sockets arranged at the intersection of the two tube truss chords 11, the extension direction of the socket is the extension direction of the socket, the extension direction of the tube truss chord 11 is the extension direction of the tube truss chord 11, and the angle β between the extension direction of the socket and the extension direction of the tube truss chord 11 is greater than or equal to 45° and less than or equal to 90°. At least six sockets are evenly distributed at the intersection of the two tube truss chords 11 at an interval of 60°, and the angle β between the extension direction of the socket and the extension direction of the tube truss chord 11 is greater than or equal to 45° and less than or equal to 90°. This arrangement can form a triangular cone between each socket and the web 13 matched with the socket and the two tube truss chords 11. Preferably, the angle β between the extension direction of the socket and the extension direction of the tube truss chord 11 is 60°, and a regular triangular cone is formed between the web 13 and the two tube truss chords 11.
[0026] As an implementation mode, the web member 13 has the same length as the tube truss chord 11 on the adjacent side of the intersection of the two tube truss chords 11, and any web member 13 and the two tube truss chords 11 form a regular triangular pyramid. The geometric properties of the regular triangle provide natural stability. When the web member 13 and the two tube truss chords 11 form a regular triangular pyramid, this structure can evenly disperse the force and reduce the risk of single-point failure. The triangle is the most basic stiffness unit in the plane, and the triangular pyramid in three dimensions can provide stronger structural stiffness. The design of any web member 13 and the two tube truss chords 11 forming a regular triangular pyramid can effectively transfer the load to the support point, reducing the use of materials while maintaining strength.
[0027] As an implementation method, the shape of the socket provided at the intersection of the two tube truss chords 11 is polygonal, and the shape of the plugs 131 provided at both ends of the web member 13 corresponds to the shape of the socket. Compared with a circle or other simple geometric shapes, the contact area between the polygonal socket and the plug 131 is larger, which can increase the friction between the two, making it difficult for the plug 131 to slide or rotate under the action of external force, and preventing the chord from rotating unnecessarily at the connection, thereby maintaining the overall stability of the structure and the expected function.
[0028] As an implementation method, the diameter and wall thickness of the tube truss chord 11 are greater than those of the web member 13. The tube truss chord 11 has a larger section moment of inertia, which can significantly improve the load-bearing capacity and bending resistance of the tube truss chord 11, making the tube truss chord 11 more suitable for bearing larger loads. A thicker tube truss chord 11 can provide better structural stability, especially when encountering lateral force or torsional force, and can better resist deformation.
[0029] As an embodiment, the reinforcement member 12 is spherical and solid. The spherical reinforcement member 12 can provide the same mechanical properties in all directions, can resist external forces in any direction without producing obvious weakened areas, and can withstand loads in non-directional or random directions.
[0030] As an implementation method, the pipe truss chord 11, the reinforcement 12, the web 13 and the fixing rod 15 are fixed and then welded at the connection. The components of the pipe truss 100 of the present application are first plugged and fixed through the holes, and the components of the pipe truss 100 are connected and fixed through the holes, and then fixed by a welding machine. Because the interaction between the components is fixed, the pipe truss chord 11 is fixed by other original parts during welding, which avoids the pipe truss chord 11 moving closer to the shrinkage direction of the weld, thereby reducing the processing accuracy.
[0031] As an implementation method, S1: prepare the required number of tube truss chords 11, web members 13, reinforcement rods 14 and fixing rods 15, and ensure that all components meet the design specifications, S2: cross two tube truss chords 11 and place them in the horizontal direction so that they form a certain angle α, and install reinforcement members 12 at the intersection, S3: drill a plurality of plug holes on the tube truss chords 11 at the intersection so that the angle β between the extension direction of the plug holes and the extension direction of the tube truss chords 11, S4: insert the web member 13 with the corresponding plug 131 into the reinforcement member 12 from the vertical direction, and insert it into the pre-punched plug hole , S5: Fix one end of the reinforcing rod 14 to a tube truss chord 11, and fix the other end to another adjacent tube truss chord 11, S6: Align the chord sleeve 151 on one end of the fixing rod 15 with a tube truss chord 11, and fix the two with fixing bolts through the through holes on the chord sleeve 151, align the reinforcing sleeve 152 on the other end of the fixing rod 15 with a reinforcing rod 14, and fix the two with fixing bolts through the through holes on the reinforcing sleeve 152, S7: Check whether each component is installed correctly, S8: After all components are fixed, weld at each connection.
[0032] As an embodiment, the lengths between the tube truss chords 11 are the same, and the lengths between the web members 13 are the same. The tube truss chords 11 and the adjacent web members 13 can form an isosceles triangular pyramid and a regular triangular pyramid, which can provide better support for the tube truss 100.
[0033] As an embodiment, the shape of the tube truss chord 11 is one of a straight line or an arc. The straight line or arc shape of the tube truss chord 11 can be more suitable for various applicable situations. When some installation positions are occupied, the arc-shaped tube truss chord 11 can be used to avoid them. The arc-shaped tube truss chord 11 can better adapt to situations where space is limited or obstacles exist. When there are other structures or equipment around the installation location, the arc-shaped chord can bypass these obstacles to avoid collision or interference. In some cases, the arc-shaped chord can provide better structural stability. For example, when it is necessary to resist lateral force or bending force, the arc-shaped chord can better disperse stress and reduce stress concentration. The arc design can provide smoother lines and increase the beauty of the structure. For projects that focus on appearance design, such as public buildings, bridges, etc., the arc-shaped chord can become a highlight in the design.
