Description

Technical Field

[0001] This utility model relates to the field of truss technology, and in particular to a steel building support truss. Background Technology

[0002] Steel building support trusses are lattice-type load-bearing structures made of steel. They optimize solid steel beams or columns into a series of interconnected triangular units, significantly reducing the structure's self-weight while maintaining load-bearing capacity. Their core working principle utilizes the inherent geometric stability of triangles to transform the load applied to the structure into axial forces within the members, thereby achieving the purpose of spanning large spaces or providing strong support. Due to their high strength, lightweight, and flexible design, they are widely used in industrial plants, stadiums, bridges, and roofs of large-span buildings, making them an indispensable backbone component in modern architecture. However, existing steel building support trusses still suffer from relatively low overall connection strength and limited flexibility in expansion.

[0003] Therefore, it is essential to invent a steel building support truss. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a steel building support truss, solving the issues of low overall connection strength and inflexible expansion inherent in existing steel building support trusses. A steel building support truss includes truss support rods, reinforcing support rods, mounting holes, reinforcing plates, connecting nodes, and extension brackets. The reinforcing support rods are fixedly installed on the inner side of the truss support rods, and the mounting holes are located inside both ends of the truss support rods. The reinforcing plates are fixedly installed on the inner sides of both ends of the truss support rods. The connecting nodes are slidably installed inside the mounting holes and fixedly installed together with the reinforcing plates. The extension brackets are fixedly installed on the outer side of the truss support rods.

[0005] The connection node includes a support base, an extension connector, a connecting pin, and bolt holes. The extension connector is fixedly mounted on the reinforcing plate through its internal bolt holes and bolts. The extension connector is fixedly mounted on the outside of the support base. The connecting pin is fixedly mounted on both sides of the extension connector and slidably mounted inside the mounting holes.

[0006] The extension bracket includes a supporting outer frame, a thickened base, connecting bolts, an extension block, and an extension connecting frame. The thickened base is fixedly installed on the outside of the supporting outer frame and connected to the truss support rod by connecting bolts. The extension block is fixedly installed on the surface of the supporting outer frame, and the extension connecting frame is fixedly installed on the top of the extension block.

[0007] The connection nodes are in four sets, and the supporting base is made of several sets of steel metal blocks with the same shape as the reinforcing plate, which connect the two sets of reinforcing plates on the two sets of trusses together; the connecting pins are two steel metal columns that are mirrored on the extended connecting body and are slidably embedded into the interior of the mounting hole.

[0008] The internal support frame of the extension bracket is made of several sets of rectangular steel metal frames, and the extension block and extension connecting frame are made of a set of steel metal brackets. The extension block and extension connecting frame can be connected to other external steel structures. The extension bracket can move in the truss support rod and its position is fixed by connecting bolts.

[0009] The truss support rod and mounting holes are connected together, and the truss support rod is made of high-strength steel profile; the mounting holes are through holes or blind holes precisely drilled at specific positions at both ends of the truss support rod, and their positions correspond to the connecting pins on the connection nodes. Compared with the prior art, the present invention has the following beneficial effects: 1. The connection node of this utility model, through the coordinated cooperation of its supporting base, extension connector, connecting pin and bolt connection hole, firstly uses the connecting pin to slide into the installation hole to achieve rapid and accurate positioning and guidance between truss support rods, and then uses bolts to fasten the extension connector to the reinforcing plate, thereby firmly connecting the ends of the two sets of truss support rods into a whole, and distributing the force to the key area reinforced by the reinforcing plate, ultimately significantly improving the strength, stiffness and stability of the connection point of the entire truss structure.

[0010] 2. The extension bracket of this utility model, through the combination of its supporting outer frame, thickened base, connecting bolts, extension block and extension connecting frame, provides an external connection hub for the truss support rod with a flexible position adjustment; its whole can move on the truss support rod and be fixed in the optimal position by connecting bolts, and finally achieve a reliable connection with other external steel structures through the extension connecting frame, which greatly improves the adaptability and expandability of the entire support system.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0016] As attached Figure 1 To be continued Figure 4 As shown.

[0017] This utility model provides a steel building support truss, including a truss support rod 1, a reinforcing support rod 2, mounting holes 3, a reinforcing plate 4, a connecting node 5, and an extension bracket 6. The reinforcing support rod 2 is fixedly installed inside the truss support rod 1, and the mounting holes 3 are located inside both ends of the truss support rod 1. The reinforcing plate 4 is fixedly installed inside both ends of the truss support rod 1. The connecting node 5 is slidably installed inside the mounting holes 3 and fixedly installed together with the reinforcing plate 4. The extension bracket 6 is fixedly installed on the outside of the truss support rod 1.

[0018] The connecting node 5 includes a support base 51, an extension connector 52, a connecting pin 53, and a bolt connection hole 54. The extension connector 52 is fixedly installed on the reinforcing plate 4 through the bolt connection hole 54 inside it and bolts. The extension connector 52 is fixedly installed on the outside of the support base 51. The connecting pin 53 is fixedly installed on both sides of the extension connector 52 and slidably installed inside the mounting hole 3.

[0019] The extension bracket 6 includes a supporting outer frame 61, a thickened base 62, connecting bolts 63, an extension block 64, and an extension connecting frame 65. The thickened base 62 is fixedly installed on the outside of the supporting outer frame 61 and connected to the truss support rod 1 by the connecting bolts 63. The extension block 64 is fixedly installed on the surface of the supporting outer frame 61, and the extension connecting frame 65 is fixedly installed on the top of the extension block 64.

[0020] The connecting nodes 5 are in four groups, and the supporting base 51 is made of several groups of steel metal blocks with the same shape as the reinforcing plate 4, and the two groups of reinforcing plates 4 on the two trusses are connected together; the connecting pin 53 is made of two steel metal columns that are mirrored on the extended connecting body 52 and are slidably embedded into the interior of the mounting hole 3.

[0021] The inner support frame 61 of the extension bracket 6 is made of several sets of rectangular steel metal frames, and the extension block 64 and the extension connecting frame 65 are made of a set of steel metal brackets. The extension block 64 and the extension connecting frame 65 can be connected to other external steel structures. The extension bracket 6 can move in the truss support rod 1 and its position is fixed by the connecting bolts 63.

[0022] The core working principle of this steel building support truss lies in its modular assembly and adjustable expansion. Its force and transmission path is as follows: the core load-bearing structure is supported by truss support rod 1, with internal reinforcing support rods 2 used to enhance the rigidity and stability of truss support rod 1, preventing instability. When connecting truss units, the connecting node 5 plays a crucial role: first, the connecting pin 53 on the connecting node 5 is aligned and slidably embedded into the mounting hole 3 at the end of the truss support rod 1 of another truss unit, achieving rapid and accurate initial positioning; then, bolts are passed through the bolt connection holes 54 of the extended connecting body 52 on the connecting node 5, fastening it together with the reinforcing plate 4 fixed to the inner side of the end of the truss support rod 1, thereby firmly clamping the reinforcing plates 4 on both sides of the supporting base 51 of the connecting node 5, ultimately forming a high-strength, high-rigidity integral node, with the load effectively distributed and transmitted through the reinforcing plates 4. Meanwhile, the extension bracket 6 serves as an external connection interface. Through its thickened base 62 and connecting bolts 63, it slides on the outside of the truss support rod 1 and locks itself in any desired position. Finally, it is flexibly connected to other external steel structures through the extension connecting frame 65 at the top of its extension block 64, thereby achieving a high degree of adaptability of the entire support system in complex construction environments.

[0023] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
