Description

Technical Field

[0001] This utility model relates to the field of building component technology, specifically to a tubular truss connection structure. Background Technology

[0002] A tubular truss is a lattice structure composed of round members connected at their ends. The round tubular members make truss structures economical in terms of material usage, lightweight, and easy to form into various shapes to suit different applications, such as simple trusses, arches, frames, and towers. Tubular trusses are one of the most commonly used structural forms in large-span buildings, widely used in stadiums, airports, railway stations, theaters, large-span factories, and bridges—buildings with high space requirements. The truss structure has a rational form, a clear force transmission path, and members are mostly based on the load-bearing axis, thus saving steel compared to other structural forms.

[0003] In existing technologies, members from multiple directions converge at connection nodes, resulting in complex assembly processes, low construction efficiency, insufficient node connection strength, and weak resistance to deformation. Summary of the Invention

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a tubular truss connection structure.

[0005] The purpose of this utility model is achieved through the following technical solution: a tubular truss connection structure, including a main truss tube and left and right web members symmetrically welded to the left and right sides of the main truss tube. At the connection between the left web member and the main truss tube, a left middle support member is welded inclined to the left front, a left upper support member is welded inclined to the left front upper, and a left lower support member is welded inclined to the left front lower. At the connection between the right web member and the main truss tube, a right middle support member is welded inclined to the right front, a right upper support member is welded inclined to the right front upper, and a right lower support member is welded inclined to the right front lower.

At the connection between the upper and lower ends of the main truss tube and the truss tube, multiple reinforcing blocks are welded in a circular array.

[0006] Furthermore, the left and right web members are respectively provided with a first bevel at one end near the main truss tube, which matches the arc-shaped surfaces on both sides of the main truss tube. The left and right web members are respectively welded to both sides of the main truss tube through the corresponding first bevels.

[0007] Furthermore, the left middle support rod has a second bevel at one end near the main truss tube that matches the connection between the left web member and the main truss tube, and the left middle support rod is welded to the connection between the left web member and the main truss tube through the second bevel; the right middle support rod has a third bevel at one end near the main truss tube that matches the connection between the right web member and the main truss tube, and the right middle support rod is welded to the connection between the right web member and the main truss tube through the third bevel.

The upper right support and the lower right support are respectively welded to the connection between the right web member and the main truss tube through the corresponding fifth bevel.

[0010] Furthermore, the second bevel has the same structure as the third bevel, and the fourth bevel has the same structure as the fifth bevel.

[0011] Furthermore, the upper left support rod and the lower left support rod are symmetrical about the transverse plane containing the central axis of the middle left support rod, and the central axes of the middle left support rod, the upper left support rod, and the lower left support rod are located in the same plane.

[0012] Furthermore, the upper right support rod and the lower right support rod are symmetrical about the transverse plane containing the central axis of the middle right support rod, and the central axes of the middle right support rod, the upper right support rod, and the lower right support rod are located in the same plane.

Detailed Implementation

[0019] To facilitate understanding by those skilled in the art, the following description is provided in conjunction with embodiments and appendices. Figure 1-2 The present invention will be further described below. The content mentioned in the embodiments is not intended to limit the present invention.

[0020] See Figure 1-2 A tubular truss connection structure includes a main truss tube 1 and left web members 2 and right web members 3, which are symmetrically welded to the left and right sides of the main truss tube 1. At the connection points between the left web member 2 and the main truss tube 1, a left middle support member 4 is welded at an angle to the left front, a left upper support member 41 is welded at an angle to the left front upper, and a left lower support member 42 is welded at an angle to the left front lower. At the connection points between the right web member 3 and the main truss tube 1, a right middle support member 5 is welded at an angle to the right front, and a right upper support member 3 is welded at an angle to the right front upper. The upper right support rod 51 is connected to the lower right support rod 52 which is welded to the lower right front. The left web rod 2, right web rod 3, left middle support rod 4, right middle support rod 5, upper left support rod 41, lower left support rod 42, upper right support rod 51 and lower right support rod 52 are all provided with plug joints 7 for welding after being inserted into the truss tube 6 at the ends away from the main truss tube 1 and at the upper and lower ends of the main truss tube 1. Multiple reinforcing blocks 8 are welded in a ring array at the connection between the upper and lower ends of the main truss tube 1 and the truss tube 6.

[0021] The tubular truss connection structure of this utility model achieves rapid positioning and welding by setting standardized plug joints 7 at one end of all members, thereby improving assembly efficiency. The setting of reinforcing blocks 8 can enhance the structural strength of the welded joints. The symmetrical layout of the left and right web members 3 and multi-directional supports forms a three-dimensional spatial truss system. The load is dispersed through the synergistic effect of supports in different directions, which significantly improves the resistance to bending, torsion and lateral displacement.

[0022] In this embodiment, the left web member 2 and the right web member 3 are respectively provided with a first bevel 21 at their ends near the main truss tube 1, which matches the arc-shaped surfaces on both sides of the main truss tube 1. The left web member 2 and the right web member 3 are welded to both sides of the main truss tube 1 through the corresponding first bevel 21. The shape of the first bevel 21 closely fits the arc-shaped surfaces on both sides of the main truss tube 1, so that the welding area forms a continuous and deep-penetrated fillet weld. Compared with planar butt joints, this significantly increases the effective weld cross-sectional area and improves tensile and shear strength.

[0023] In this embodiment, the left middle support 4 has a second bevel 43 at its end near the main truss tube 1, which matches the connection between the left web member 2 and the main truss tube 1. The left middle support 4 is welded to the connection between the left web member 2 and the main truss tube 1 through the second bevel 43. The right middle support 5 has a third bevel 53 at its end near the main truss tube 1, which matches the connection between the right web member 3 and the main truss tube 1. The right middle support 5 is welded to the connection between the right web member 3 and the main truss tube 1 through the third bevel 53. The shapes of the second bevel 43 and the third bevel 53 match the contour of the connection, making the weld area transition smoothly. Furthermore, the deep penetration weld formed by the second bevel 43 and the third bevel 53 creates a rigid connection between the left middle support 4, the right middle support 5, the web member, and the main truss tube 1, significantly improving the overall stiffness of the node and suppressing the micro-vibration of the truss under dynamic loads.

[0024] In this embodiment, the upper left support 41 and the lower left support 42 are each provided with a fourth bevel 44 at the end near the main truss tube 1, which matches the connection between the left web member 2 and the main truss tube 1. The upper left support 41 and the lower left support 42 are welded to the connection between the left web member 2 and the main truss tube 1 through the corresponding fourth bevel 44. By providing the fourth bevel 44, the upper left support 41 and the lower left support 42 can be tightly connected to the connection between the left web member 2 and the main truss tube 1, significantly improving the overall stiffness of the node and suppressing the micro-vibration of the truss under dynamic loads.

[0025] In this embodiment, the upper right support 51 and the lower right support 52 are each provided with a fifth bevel 54 at the end near the main truss tube 1, which matches the connection between the right web member 3 and the main truss tube 1. The upper right support 51 and the lower right support 52 are welded to the connection between the right web member 3 and the main truss tube 1 through the corresponding fifth bevel 54. By providing the fifth bevel 54, the upper right support 51 and the lower right support 52 can be tightly connected to the connection between the right web member 3 and the main truss tube 1, significantly improving the overall stiffness of the node and suppressing the micro-vibration of the truss under dynamic loads.

[0026] In this embodiment, the second bevel 43 and the third bevel 53 have the same structure, and the fourth bevel 44 and the fifth bevel 54 have the same structure. The identical bevel design simplifies the manufacturing process and facilitates welding.

[0027] In this embodiment, the upper left support rod 41 and the lower left support rod 42 are symmetrical about the transverse plane containing the central axis of the middle left support rod 4, and the central axes of the middle left support rod 4, the upper left support rod 41, and the lower left support rod 42 are located in the same plane. The middle left support rod 4, the upper left support rod 41, and the lower left support rod 42 form a symmetrical triangular support structure in the same plane, which can resist shear forces in the plane and significantly improve the stiffness and deformation resistance in that plane direction.

[0028] In this embodiment, the upper right support rod 51 and the lower right support rod 52 are symmetrical about the transverse plane containing the central axis of the middle right support rod 5, and the central axes of the middle right support rod 5, the upper right support rod 51, and the lower right support rod 52 are located in the same plane. The upper right support rod 51, the lower right support rod 52, and the middle right support rod 5 form a symmetrical triangular support structure in the same plane, which can resist shear forces in the plane and significantly improve the stiffness and deformation resistance in that plane direction.

[0029] In this embodiment, the angle between the upper left support rod 41 and the middle left support rod 4 is 30-50°, and the angle between the upper right support rod 51 and the middle right support rod 5 is 30-50°. To achieve the best performance of this invention, the angle between the upper left support rod 41 and the middle left support rod 4 is set to 40°, and the angle between the middle right support rod 5 and the upper right support rod 51 is also set to 40°.

[0030] In this embodiment, the angle between the left middle support rod 4 and the right middle support rod 5 is 110-130°. To achieve the best performance of this invention, the angle between the left middle support rod 4 and the right middle support rod 5 is set to 120°.

[0031] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this utility model are within the protection scope of this utility model.
